Podcasts about green software

Host Anne Currie is Joined by the esteemed Charles Humble, a figure in the world of sustainable technology. Charles Humble is a writer, podcaster, and former CTO with a decade's experience helping technologists build better systems—both technically and ethically. Together, they discuss how developers and companies can make smarter, greener choices in the cloud, as well as the trade-offs that should be considered. They discuss the road that led to the present state of generative AI, the effect it has had on the planet, as well as their hopes for a more sustainable future.

In deze aflevering spreken we met Wilco Burggraaf over een onderwerp dat steeds relevanter wordt: green software development. Wat betekent dat eigenlijk, en hoe kunnen developers concreet bijdragen aan duurzamere digitale oplossingen?We verkennen:Het verschil tussen energie-efficiënte en duurzame softwareHoe je als developer groene keuzes maakt in code, architectuur én cloudgebruikWelke tools er zijn (denk aan Cloud Carbon Footprint en The Green Software Foundation)Of duurzaamheid ook kostenbesparing oplevertEn... hoe LLM's zoals GPT-4 in dit plaatje passenWilco deelt zijn inzichten uit de praktijk, en natuurlijk bespreken Dibran en Remco ook hun technische highlights — van cloud-agnostische keuzes tot AI-tools die developers slimmer maken.

Chris Adams sits down in-person with Max Schulze, founder of the Sustainable Digital Infrastructure Alliance (SDIA), to explore the economics of AI, digital infrastructure, and green software. They unpack the EU's Energy Efficiency Directive and its implications for data centers, the importance of measuring and reporting digital resource use, and why current conversations around AI and cloud infrastructure often miss the mark without reliable data. Max also introduces the concept of "digital resources" as a clearer way to understand and allocate environmental impact in cloud computing. The conversation highlights the need for public, transparent reporting to drive better policy and purchasing decisions in digital sustainability.

A year ago, Building Green Software was released by O'Reilly. Since Tim Frick's book “Designing for sustainability” (8 years ago!), O'Reilly didn't publish anything fully focusing on sustainability. So, it's a fair statement that this book was long awaited. But a year is an eternity in IT. This is why Sarah Hsu, one of its 3 co-authors as well as the chair of the Green Software Foundation's Principles of Green Software committee, joined the show to talk about the trends she witnesses first hand in the green software engineering field and how she would envision a v2. More specifically she talked about:

Host Anne Currie is joined by the seasoned Chris Liljenstolpe to talk about the latest trends shaping sustainable technology. They dive into the energy demands of AI-driven data centers and ask the big question around nuclear power in green computing. Discussing the trajectory of AI and data center technology, they take a look into the past of another great networking technology, the internet, to gain insights into the future of energy-efficient innovation in the tech industry.

In this episode, Chris Skipper takes us backstage into the Green Software Patterns Project, an open-source initiative designed to help software practitioners reduce emissions by applying vendor-neutral best practices. Guests Franziska Warncke and Liya Mathew, project leads for the initiative, discuss how organizations like AVEVA and MasterCard have successfully integrated these patterns to enhance software sustainability. They also explore the rigorous review process for new patterns, upcoming advancements such as persona-based approaches, and how developers and researchers can contribute.

For this 100th episode of Environment Variables, guest host Anne Currie is joined by Holly Cummins, senior principal engineer at Red Hat, to discuss the intersection of AI, efficiency, and sustainable software practices. They explore the concept of "Lightswitch Ops"—designing systems that can easily be turned off and on to reduce waste—and the importance of eliminating zombie servers. They cover AI's growing energy demands, the role of optimization in software sustainability, and Microsoft's new shift in cloud investments. They also touch on AI regulation and the evolving strategies for balancing performance, cost, and environmental impact in tech.

Have you ever heard “The complaint of the lonely sustainability champion”? Its IT sector version? Here it is “I listen to the Green IO podcast and others as well, I read newsletters and articles from CAT, GWF, Boavizta, Greenit.fr, GSF, etc. But I'm isolated as a green software champion. I have the feeling that I cannot achieve much by myself. How could we actually do green software in my company?” This episode is all about sharing one concrete use case of someone, Annie Freeman, who achieved to build and deploy an internal tool monitoring carbon emissions in a SaaS company, Xero, with more than 4M users of its accounting software across a dozen countries. This achievement, among others, has won her to be named a finalist in the New Zealand Sustainable Business Network Awards in 2024 And she started it all by herself when she raised her voice in 2022 at a Xero's internal technology conference despite having joined the company as a software engineer just a few months ago. In this episode, Annie Freeman shares great insights with host Gaël Duez on:

A recent study by Nielsen IQ found that 78% of us consumers say that a sustainable lifestyle is important to them. And while attractions have been great at a wide range of initiatives to improve their sustainability, this year's Visitor Attraction Website Survey will show that as a sector, we're lagging behind on digital sustainability. Paul Marden: So in today's episode, I'm going to talk about the learning journey I've been on personally, along with my colleagues at Rubber Cheese, to understand digital sustainability and how to affect real change. Paul Marden: I'll talk about what I've learned from hosting this podcast and how we've started to make real changes to our processes and our client sites to make them more sustainable. Welcome to Skip the queue. I'm your host, Paul Marden. Paul Marden: Back in April, I spoke to Polly Buckland from The Typeface Group about the importance of sustainability reporting. Polly Buckland: There's buckets of research out there as to the relationship between consumer behaviour and sustainability. So McKinsey did a study. “60% of customers actively prioritise purchasing from sustainable businesses.” Capgemini, “77% of customers buy from and remain loyal to brands that show their social responsibility.” I could literally keep quoting stats as to why businesses should take their sustainability goals very seriously and the communication of their sustainability initiatives very seriously, because it's becoming clearer. There was another stat about primarily women making the decisions based on sustainability of a business, and Millennials and Gen Z being sort of high up the list of people that are taking sustainability creds into consideration when they're making a purchase. So, I mean, it's a barrel load of stats that suggest if you don't have your eye on sustainability reporting and communicating your sustainability goals, you perhaps should have. Paul Marden: Of course, many attractions have been blazing a trail on the subject of sustainability for years. Going back in the archives of Skip the Queue to 2021, Kelly spoke to Lucy Downing, the Head of Marketing, and Sue Penlington, the Sustainability Manager for the Holkham Estate. First, let's hear from Kelly and Lucy. Kelly Molson: Lucy, I wondered if you could just give us an overview of Holkham Estates for our listeners that might not be aware of you or visited there themselves. Lucy Downing: So if you sort of picture it, most of the time when you think about stately homes, you picture a stately home with a garden. At Holkham, we are very much a landscape with a stately home. So 25,000 acres. We have a national nature reserve. A beach, b eautiful beach. It's been in Shakespeare in love. If you know the final scenes of Gwyneth Paltrow walking across the sands, that's Holkham, a bsolutely stunning. We're a farm, but at the centre of that, we've also got our 18th century palladian style mansion and that's home to Lord Lady Leicester and their family. They live in the halls. It's a lived in family home. But then we also have all of our visitor facing businesses. Lucy Downing: So we've got the hall, our Holkham stories experience, which is an attraction museum telling us all history and the now and the future of Holkham. Lucy Downing: We've got a high ropes course, cycle hire, boat hire, normally a really buzzing events calendar. We have accommodations. We've got Victoria Inn, which is near the beach. We've also got Pine Woods, which is a holiday park with caravans and lodgers. We have our self catering lodges, which within the park. And then we've got farming, conservation, gamekeeping, land and properties. We've got nearly 300 properties on the estate that are tenanted. A lot of those people work for Holkham, or if not, they work in the local community. We've got forestry and then we've also officiated and it's won lovely awards for the best place to work in the UK. It's a stunning landscape that surrounds it and we've got. I don't know if you've heard of her, but Monica Binnedo, which is global jewellery brand, she's based at Longlands at the offices. Lucy Downing: She decided a few years back to base her whole business there. She got all of her shops around the world, but that's where her business is. And I think she's ahead of the times, ahead of this year. She sort of knew how wonderful it would be to be working, I suppose, and not in a city centre, so I hope that gives you a flavour. But, yeah, I think it's 25,000 acres of beauty, landscapes with a house in the middle and lots of wildlife. Kelly Molson: I mean, it really is one of the most beautiful places and that stretch of the world holds a really special place in our hearts. It's somewhere that we visit very frequently and it's stunningly beautiful. Paul Marden: Later in that episode, Sue shared her insights on their sustainability strategies. Sue Penlington: So we've got three main themes. One is pioneering environmental gain I, which is all about connecting ecosystems and biodiversity and habitats. One is champion low carbon living, which is all about carbon emissions, our impact on construction and housing, our leisure operations. That sort of thing, and farming. And then the last one is the one that we always talk about. Tread lightly, stamp out waste. So that's all about recycling, reducing single use plastics and that sort of thing. So those three themes are what we're running with for 2021. We've got three goals, which are quite ambitious as well. And for me, I just see 2021 as that year of change where we'll make an impact. So we've done quite a lot of talking, and rightly so, and we want to take our visitors on that journey and really start to chip away at those goals. Paul Marden:  Now, let's talk a little bit about the fears around talking about sustainability. I think one of the things that is getting in the way of an open discourse around digital sustainability is fear. We're afraid of being judged by our actions and our intentions. In a recent survey by Unilever of social media influencers, 38% were afraid to openly discuss sustainability for fear of being accused of greenwashing. Again, let's hear from Polly, which is. Polly Buckland: Why, again, that storytelling part of the impact reporting is really important for me, because I will say we are not perfect. These are the things that we know we need to work on, but these are the things we've done better. And that's what I really like. The BCorp BIA assessment and their framework is because it takes you across five categories of measurement, and no one's perfect in any of them, but what it does do is it provides a framework for you to better. Paul Marden: Yes, absolutely. Polly Buckland: And measure yourself against. Yeah, I think if. I think the messaging behind your sustainability is really important. If you're professing to be perfect and you're not, you will get stung, because I think people can see through that. But if you are showing that you're trying to better, I don't think many people could argue with that. Paul Marden: Now, let's rewind a little and talk about my interest in digital sustainability. When I spoke to James Hobbs of the aer studios about digital sustainability back in July, we talked about my ignorance. So my background was at British Airways and I was there for ten years. It really wasn't that hard to spot the fact that environmentally, that we have a challenging problem, because when you stood on the end of Heathrow Runway, you can see what's coming out the back end of a 747 as it takes off. But I don't think I ever quite understood the impact of what I do now and how that's contributing more to CO2 emissions than what I was doing previously, which, yeah, I just don't think there's an awareness of that more broadly. James Hobbs: No, yeah, I'd agree. And it's complicated. Paul Marden: In what way? James Hobbs: I guess it's complicated to quantify the carbon impact of the type of work that we do in the digital industry because I guess there's what we're shipping to end users, which is one thing, but most modern websites and applications and stuff are built on a big tower of cloud services providers and all of their equipment has to be manufactured which has a carbon impact and rare earth metals need to be mined out of the grid. All of that stuff. Theres a big supply chain backing all this stuff and we can influence some of that directly, but a large chunk of it, we cant. So it makes choosing your suppliers quite important. Paul Marden: But in a presentation by my friend Andy Eva-Dale, now CTO of the agency Tangent, he opened my eyes to the impact that the digital sector has on the environment. The Internet consumes 1021 terawatt hours of electricity per year. That's more than the entire United Kingdom. Globally, the average webpage consumes approximately 0.8 grammes of CO2 per page view. For a website with 10,000 monthly page views, that's 102 kilos of CO2 per year. And as we'll see in a bit, the Rubber Cheese Visitor Attraction Website Survey shows this year that the websites in our sector are anything but average. But let's talk about my learning journey. I've used this podcast as a way to learn about the sector and to drill down into sustainability itself. My interviews with Polly and James taught me a lot. It's one of the real benefits of running a podcast. Paul Marden: I can sit and ask people questions that in real life they may not want to talk about. Beginning from absolute first principles. Following the advice from James in the podcast, I've gone and studied the online materials published by the Green Software foundation, including their green software practitioners certificate. Some of that is quite technical, but a lot of what's in there is a real interest to a lot of people. Now let's talk a little bit about what I've learned along that journey. In an interesting conversation with Andy Povey the other day, he talked about people's innate reaction to digital sustainability and that for many people, the move to digital feels sustainable. I'm not printing things out anymore, so it must be sustainable. Of course, all that computation and networking has a massive global impact on greenhouse gas emissions, so not every website is sustainable. Paul Marden: In another conversation I had recently, someone said to me, why does all of this digital sustainability stuff matter? If I host my site on a green hosting server, there's no harmful emissions from the server. But that's only one part of a complex web. The power needed to connect up all the servers in the world and to all of the endpoint devices is immense. Of course, the carbon emitted to generate power varies country by country as well as by time. And that's not really in our control. But we can definitely control the impact our website has on all of that infrastructure. As the web page is in flight over the Internet to somebody's mobile device, the power it uses and consequently the carbon emitted along the way is therefore something that's definitely in our control. Paul Marden: The other source of learning for us this year has been the sustainability elements of the rubber cheese survey of visitor attraction websites. We made sustainability a core theme of this year's survey and we found some really interesting things. 80% of attractions in our survey have got some sort of sustainability policy, which is an amazing achievement and sets a benchmark for the sector. Also, a number of attractions are taking active steps to improve the sustainability of their website. But we found that this isn't necessarily being done in a framework of measuring and monitoring the sustainability of their website. So the changes that people are making could be making improvements to the sustainability of their site, but at worst, some of the techniques being used could actually harm the performance and sustainability of the website. Paul Marden: The thing is, if you're not testing and measuring, you can't ever know whether the changes that you're making are effective. The Green Business Bureau talk about how benchmarks provide a reference point to assess trends and measure progress and baseline global data. They say, "Companies have begun measuring sustainability performance, which allows them to make continuous assessments, evaluate where they lie on the sustainability agenda and make data driven decisions and policies. Measuring sustainability requires proper selection of key sustainability metrics and a means of making effective process improvements. These measures provide real time data and much needed quantitative basis for organisations to strategise and mitigate environmental and social and economic risks." I'll come back to making process improvements later, but for now let's just stick with measures. Back to James Hobbs, who talked about the ways in which you can measure the CO2 emissions on our website. James Hobbs: There are some tools out there that you can use to help you quantify the carbon impact of what you've got out there in the wild now. So the big one that most people talk about is websitecarbon.com, which is the website carbon calculator that was built by, I think a combination of an agency and some other organisations come up with an algorithm, it's obviously not going to be 100% accurate because every single website app is slightly different and so on, and as a consistent benchmark for where you are and a starting point for improvement. Tools like that are really good. Ecograder is another one. Those offer non technical routes to using them. Paul Marden: Now, both of these websites use similar technologies and methodologies to understand the CO2 emissions of a website. But the survey shows more than half of attractions have never tested the CO2 emissions of their site. This got me thinking. If it's that easy to test the sustainability of a single webpage and you can run them on any website, but most attractions aren't doing it, then what can we as Rubber Cheese do to help? So in this year's survey, we've run the largest audit of visitor attraction sustainability scores that we're aware of. So working with our lovely podcast producer Wenalyn, who also supports me with the survey, firstly, I run a proof of concept gathering and comparing data for a small number of attractions in our database this year. Paul Marden: Once we began to better understand the data, Wenalyn went and ran this against all of the sites that were in our database. With this, we hope to support the sector with a benchmark of webpage sustainability that can be used by anyone in the sector. And what this has shown us is that 58% of attraction websites are rated f by Website Carbon. That's 8% worse than the general population of all websites. But the sobering thing for me as an agency owner is that the sites that we build were in that 58%. The work that we've been doing recently isn't good enough from a sustainability perspective. So this triggered a number of projects internally for us to improve the sustainability posture of the sites that we design and build. Paul Marden: So I'm going to dig into one of those sites and the journey we've been on to remediate the sustainability of their site, because I think it can give a really nice understanding of the journey that you have to go on, the changes that you can make, and what the impact of those changes could be. Now, we started by benchmarking the scores for the site in question from Website Carbon and Ecograder. And this site was a grade F and marked 51 out of 100 by Ecograder. From there, we drove our improvements off of the feedback that Ecograder gave us. We worked as a team to estimate the work involved in the feedback from Ecograder to identify the tasks with the lowest estimated effort and the highest potential impact. Paul Marden: Essentially going for the quick wins, we implemented a number of really simple measures, we implemented lazy loading of images. This is making the browser only download images when they're just about to show on screen. If you don't lazy load an image on a page, then when the webpage opens, the browser will go and grab the image, calculate the size, and redraw the webpage with that image in it, even though the image is off screen. If the user then clicks something in the top part of the screen, maybe in the top navigation, and they never scroll down, they will never see that image. So all that network traffic that was used, all the computation in the browser to be able to figure out the size and paint the screen, was completely wasted because the user never got to see the image. Paul Marden: So by lazy loading, it means that if a person doesn't scroll all the way down the page, then an image near the bottom of the page will never get loaded. And it's an incredibly simple code change that you can write in now. This used to be something that you had to write custom code to implement, but most browsers now support lazy loading, so it should be really easy for people to implement that. Paul Marden: Another thing that we did was to correctly size images. We found that, but with best rule in the world, our editors were uploading images that were very high resolution, very big images, even though on screen we might only show a thumbnail. By resizing the images inside WordPress, we've made it easy for our editors to upload whatever size image that they like. But we only share the smaller image when somebody views the webpage, again, cutting down network traffic as a result of that. One other thing that we made a change on was to make the website serve more modern image formats. Paul Marden: Again, we used a WordPress package to do this, called imagify, and it means that our editors can upload images using the file formats that they're familiar with, like JPEG, GIF and PNG, but that we convert them to more modern formats like WebP inside WordPress. And that has better compression, making the images smaller without any discernible loss of quality, and making the whole webpage smaller, lighter, faster as a result of it, which has the impact of reducing the CO2 emissions that are needed to be able to use that webpage just as a guide. We measure everything that we do in the business in terms of the time it takes us to do things. So we're real sticklers for time tracking, but it was really important in this project for sustainability to work out what the differences were that were making. Paul Marden: So these changes, those three that I just outlined there cost us about a day and a half of development effort and much of that was done by one of our junior developers. So it wasn't hugely complex work that was done by an expensive, experienced developer. But in return for those changes, that one and a half days of effort, we've seen an improvement in rating by website carbon from F  to B and on eco grader from 54 out of 100 to 83 out of 100. This puts the site well into the realm of better than most websites on the Internet and better than 84% of attractions in this year's survey. Is it enough? No, of course not. We can do more and in fact, there are still technical improvements that we can make that don't impinge at all on the user's experience. Paul Marden: We can and we will make more changes to move the site from B to A or even to A+. But there's no doubt that following the old 80-20 rule, these marginal gains will be progressively harder and more costly to achieve. And there may be changes that are needed that will impinge on the user experience. Some things you cannot improve from a sustainability perspective without changing what the user is going to experience. If you've got an auto playing video on your website that consumes bandwidth, it generates network traffic. You cannot remove that video without removing the video entirely and changing it to be something that isn't autoplay but plays w hen a button presses that will have an impact on the user experience. Not everyone will click that button. Paul Marden: Not everyone will watch that video and say not everyone will necessarily have the same feeling about the attraction that they got when there was an autoplay video in place. But there are undoubtedly lots of things that can be done that don't impact the user experience of the site. One of the changes that we still haven't made, which is a little bit more effort, it's a little bit more complexity, and adds a little bit of costs to the hosting of the website is the introduction of a Content Delivery Network or CDN. Here's James Hobbs again from aer. James Hobbs: From a technical angle, I think one of the most impactful things you can do, beyond making sure that your code is optimised and is running at the right times, at the right place, is simply to consider using a content delivery network. And for your listeners who aren't familiar with a content delivery network, a CDN is something that all of us have interacted with at one point or another, probably without realising. In the traditional way of serving or having a website, you've got some service somewhere in a data centre somewhere. When someone types your website address in, it goes and fetches that information from the web server and back comes a web page in the simplest sense. James Hobbs: Now, if your website servers live in Amsterdam and your users on the west coast of America, that's a big old trip for that information to come back and forth, and it's got to go through lots of different hops, uses up lots of energy. A Content Delivery Network is basically lots and lots of servers dotted all over the planet in all of the major cities and things like that can keep a copy of your website. So that if someone from the West Coast of America says, "Oh, I'm really interested in looking at this w ebsite.", types the address in, they get the copy from a server that might be 10,20, 50 miles away from them, instead of several thousand across an ocean. James Hobbs: So it loads quicker for the user, which is great from a user experience, SEO, but it's also great from an energy point of view, because it's coming from somewhere nearby and it's not having to bounce around the planet. That's one thing that you could do that will make a massive and immediate impact commercially and from a sustainability point of view. Paul Marden: So there's another example of something that you can do that has very little impact on the experience of the website. In fact, it massively improves the user experience of the website, takes relatively little effort, but offers a huge improvement. Those are all things that we've done to one individual website. Let's talk a little bit about how we bake that into our process. In a 2022 article in the Harvard Business Review about how sustainability efforts fall apart, they recommend embedding sustainability by design into every process and trade off decision making. I found that language really interesting. It's similar to the language used widely in technology and security that was popularised during the launch of the EU General Data Protection Legislation, which talks a lot about having a security by design approach. Paul Marden: So taking this idea of designing sustainability into every process and trading off the decision making, we've incorporated it into our sales proposal, writing, designing and testing processes. Our people responsible for selling need to bake sustainability into the contract. We want to hold ourselves and our clients accountable for the sometimes difficult decisions around meeting a sustainability target. So we'll discuss that target at the beginning of the project and then hold ourselves to that throughout the design and build process, thereby not needing to do all the remediations that we've just done on the other website, because it's typically much easier, quicker, cheaper for us to implement a lot of those things. The first time through the project, as opposed to as a remediation at the end. We've also baked sustainability testing into our process. Paul Marden: No site goes live without having been tested by both website carbon and eco grader to make sure that the site meets the criteria that we set out at the beginning of the work. So we've thought a lot about how we can improve what we do and we've started to go back and remediate over some of the work that we've done more recently to make improvements. But my learning journey hasn't been entirely smooth. There are challenges that I've hit along the way. I think there's a few interesting challenges that are to be expected as you're going about learning things that I wanted to share. For example, we've done work to remediate the scores of one of our sites and been super excited with the impact score. Paul Marden: I mean, went from bottom of the Fs to A+, only to deploy those changes into production and it didn't move the dial at all on the production website. And that was heartbreaking. Once we looked into that in more detail, thinking that we've done loads of changes, move the dial such a dramatic amount, only to launch it into the wild and it barely touched things. What we realised that in the test environment that we used, we had password protection in place and the website carbon and Ecograder were testing the password screen, not the actual homepage underneath it. So there was a lesson learned for us. The other area where we've made lots of learnings is during the survey when we created our sustainability benchmark. We've seen test results so good that they can't be explained. We've seen somebody hitting 100 on Ecograder. Paul Marden: We've also seen scores that were contradictory on Ecograder and Website Carbon, and also scores that have dropped dramatically. When we first tested in August and did a validation test checked last week, we're still working our way through these wrinkles and I think some of it is because we're looking at many hundreds of websites rather than trying to learn by testing and improving just one site. But beyond the kind of technical challenges, there remain some things that I simply don't understand. And my mission going forward is to fill those gaps. Firstly, while both Ecograder and Website Carbon use the same underlying principles and tools to calculate CO2 emissions, they often can and do give different results. Paul Marden: Not just in the fact that one is A+, a F score and the other is out of 100, but that the basic page sizing in kilobytes and consequently the CO2 can and often is different depending on which tool you look at. And I don't understand why that is, and I need to look into that. And I'm sure we'll come back to the podcast and talk more about that once I do understand it better. But the other problem is that I'm struggling with the size of the problem and the size of the prize. There's no doubt in my mind that making these improvements is the morally right thing to do, and commercially it's right as well, because it improves your outcomes on the website as well as the sustainability. Paul Marden: I'm just struggling with the business case, because if I had an unlimited budget, I do make every change in business that improves the sustainability posture of the business. But most marketers, most people that listen to this podcast don't have an infinite budget. They have a very finite budget, and so they have to put their budget to work where it's going to have the most impact. And what's the return on investment of spending 5k on improving the website versus changing light bulbs to leds, or moving away from gas powered water heaters in the outside toilets by the penguins? It's really difficult at the moment for me to be able to understand where this is the right and sensible investment of sustainability funding within an organisation. So I've shared my learning journey over the year. What about you? What can you do next? Paul Marden: For one last thought, let's head back to the conversation between Kelly and Lucy and Sue from Holkham. Kelly Molson: Are there any advice that you could share with our listeners in terms of how they start or begin to look at sustainability? Lucy Downing: Interesting. I was chatting with Lord Leicester yesterday about the subject and were sort of agreeing that I think you definitely need to know where you are, particularly as a business. You know where you are, because then you can set your goals in a realistic fashion. And I think the one thing to remember is that it has to be realistic, because you need to set goals that you can financially deliver, because if they're not financially viable, then you're not going to be here as a business to deliver them. And what we're also finding and talking to other businesses that actually quite a lot of the sustainability gains that you can make are actually in financial ones too, because you probably cut down on some of your resources that you're using, you'll think better, you'll work smarter. Lucy Downing: So it's just, I think that's something to definitely remember, that it has to be sustainable in all ways, socially, financially and environmentally. That's definitely some key advice. And I think be authentic. There's a lot of talk around greenwashing. Don't be guilty of thinking, wow, this is something we really should do and we're going to do it and just talk about it. It has to be authentic. So really think about where you can make the biggest changes environmentally for sustainability and focus on those and just make sure. Yeah, it's like us really. We're saying we're launching our sustainability strategy, but actually for the past ten years, we've now we've got 100 acre solar farm, we've got anaerobic digester, we heat the hall and all of our businesses with woodchip, so we've got our biomass boilers. Lucy Downing: So we've been doing it for quite a long time without telling anyone. But what we're now doing is saying, actually, that's not even enough, we need to up it further. So, yeah, that's the thing. I think it just has to be authentic and realistic. Sue Penlington: Yeah. And from my point of view, I'm a bit of a doer do and not a talker, so don't get bogged down. It could be absolutely overwhelming. And I think when I was first approached by my boss here, I was just like, wow. Because it isn't just rubbish, it's every single business. Sue Penlington: It's huge. But from my point of view, small differences can make a really big impact and keep chipping away at it because solutions are out there. There's loads of people doing really cool things. And, you know, every night I'm on Google looking up something else or going down another rabbit hole because I've seen something on Twitter. So for me, every day is a school day. But, yeah, get stuck in and collaborate with other like minded people. You know, nowadays you're not considered swampy because you're talking about sustainability. Sue Penlington: Well, you know, it's totally on brand, isn't it? And let's not reinvent the wheel. If we can learn from other people, then let's do that. I mean, go for it. Literally, every single individual can make a difference. Kelly Molson: Oh, Sue, that's. Yeah, you've just got me right there, sue. And I think what you said about collaborating and learning from people, that has been something that's so key this year. People are so willing to share their plans, they're so willing to share what they're doing and how they're doing things. Especially within this sector, there's always somebody that's doing or, you know, a couple of steps ahead of you that you can learn from. And people are so willing to kind of give up that advice and their time at the moment as well. So definitely that's a key one for me. Ask people. Ask people for help. Ask people how to do things. Paul Marden: I'd like to thank everyone that contributed to this episode, including Kelly, Lucy and Sue at Holkham, Polly at TFG and James at aer. Thanks to everyone that's helped me with this journey in the last year, the lovely clients we've talked to, the survey respondents, and my team at Rubber Cheese, Steve, Ben, Tom, Sinead, Wenalyn, and Oz, who've all worked really hard to benchmark the sector and to make continuous improvements to our client's sustainability. As you know, we're really experimenting with the podcast format at the moment, and if you like this or any of the other changes, I'd love to hear. And if you don't, then tough, go make your own podcast. Only joking. I'd love to hear. If you think we can make improvements, you can find me on X, @paulmarden and also on LinkedIn. Paul Marden: If you're at VAC this week, the Visitor Attraction Conference, then I'll be there with Oz and Andy.

I'm your host, Paul Marden. The last twelve months have been the warmest of any twelve month period since records began. And while over 70% of attractions have a sustainability policy, only 12% have actually tested the CO2 emissions of their website. In today's episode, we're joined by James Hobbs, Head of Technology at Air Studios and a member of the Umbraco Community Sustainability Team. James shares some easily actionable tips to reduce the emissions of your website. Paul Marden: James, welcome to skip the queue. Lovely to have you. James Hobbs: Thanks for having me. Paul Marden: So we always start with some icebreaker questions. So it would be unfair if I didn't inflict the same pain on you. James Hobbs: Go for it. Paul Marden: Let's start with a nice one, I think. What actor would you want to play you in a film about your life? James Hobbs: I mean, instinctively, I'd say someone like Jack Black. Just think he's really funny. A lot more funny than me. I'm not sure how much of a resemblance there is. He's got a much better beard than I do someone. Yeah. If there's gonna be an adaptation, I'd like it to be funny. Paul Marden: I like the idea of that one. I think I'd struggle with that one. I'd struggle to pick. Yeah, you know, it's gotta be an archetypal geek that would play me in the story of my life. I'm not sure who that would be. James Hobbs: Not John Cena or something like that. Paul Marden: So the next one, I'd say this one I found really hard, actually. What was your dream job when you were growing up? James Hobbs: Oh, okay. So I can answer that one easily because my parents still take the Mickey out of me for it. So when I was quite young, I told them very kind of certified. When I grow up, I want to be part time mechanic, part time librarian. Paul Marden: Well, that's an interesting job, shed. James Hobbs: Yeah, it's really random, I think, because I like, I love books. I love reading. Did back then, still do now. I also like dismantling things. I was never very good at putting them back together and then continuing to work. But, yeah, that was my aspiration when I was a kid. Paul Marden: I remember going to careers advisors and just some of the tosh, they would tell you. So everybody was told they could be an undertaker and you got your typical finance jobs. But I really. I desperately wanted to be a pilot. And I was told by the optician I couldn't because of eyesight, which was nonsense. But actually, I couldn't have done the job because I have a zero sense of direction. So later in life, when I trained for my private pilot's license, I got hopelessly lost a couple of times. The RAF are very helpful, though, when that happens. James Hobbs: They come up, fly alongside you and tell you to get out of their airspace. Paul Marden: They don't like people invading the Heathrow airspace. And I was dangerously close to it at the time. James Hobbs: Nice. Paul Marden: That's another story, though. But no, they sent me from my work experience to work in the local council finance department. Department, which I don't think could be more different than being a pilot if you actually tried. James Hobbs: I mean, it's not the most glamorous, I mean, it's important, but, you know, it's not quite Top Gun, is it? Paul Marden: No, no. Exactly. There you go. Tom Cruise. That can. He can play me in the film of my life. James. So we want to talk a little bit about digital sustainability. So I thought it'd be quite nice for you to tell the listeners a little bit about your background in digital and more specifically the stuff that you've been doing more recently in digital sustainability. James Hobbs: Okay, I'll give you the most succinct property history I can. So I guess my background 15, 16 years ago started off as a developer, not a very good one. And since then I've worked for a range of different sorts of organisations. So everything from a local council, national charity, global manufacturing company, and then two digital agencies. For the last ten years or so, I've been more in leadership positions, obviously have to stay close to the technology. And in more recent years, one of the big passions of mine, I suppose, or something I'm really interested is the sustainability side of digital, because I think it's interesting and that we can make a massive impact, which I'm sure we'll talk about at some point. James Hobbs: But my current role is I'm Head of Technology at a creative technology studio called Air Studios, who also share my enthusiasm for sustainability. So I'm excited to do some work there. Paul Marden: Yeah. And my background stalking of you told me that air does some work in the attraction sector as well, doesn't it? So you work with a few attractions? James Hobbs: Yes, that's right. Yeah, we've got a few. Paul Marden: So there's some form here. James Hobbs: Yeah, I would say so. Paul Marden: Cool. One of the things that I know that you've been working with is so we're both. We've spent a lot of time in the Umbraco community, and Embraco is a content management system that a few attractions use not many, but some tend to be larger organisations that use Umbraco typically. But we've both spent time in the Umbraco community going to lots of events and talking to a lot of people. But one of the contributions you've made over the recent period is joining the Umbraco Sustainability Team. What is it, what does it do and who's involved in it? James Hobbs: Okay, so the Umbraco has this concept of community teams, which I think is a, Umbraco is a very unique organisation. Anyway, you know this because you're part of community as well, but they have a very strong connection and link with the community of developers. And not just developers, anyone who has anything to do with Umbraco and works with it. And the sustainability team is one of the several community teams that exist. The idea is that it brings together people from Umbraco's and people from the community who have a shared passion in something relevant to Umbraco to help steer it, share knowledge, and ultimately achieve a goal. And for the sustainability community team, the goal is to, I guess it's multifaceted. Firstly to make Umbraco as a product more sustainable, which is brilliant. James Hobbs: Secondly, to raise awareness of what organisations or individuals need to do to be able to improve the sustainability posture of whatever they're up to, which is brilliant as well. So there's a very umbraco focused side to it, but there's also a wider kind of awareness raising, educational side of it too, because this is a very, its a quite a new, say, it's a relatively new thing. I think digital sustainability as a concept completely hasn't really existed for that long, unfortunately. But now it does. Paul Marden: Yeah, exactly. And theres been some impact as well that the team has had on the product and the direction of the product isn't there. James Hobbs: Yeah. So and again, this is, there's several of us in this community team and I want to make it really clear that like a lot of work's gone on. It's not just me doing it. So we've managed to achieved a few things. So first of all, the Umbraco website, they launched a new website a little while ago. Its sustainability posture wasn't great. So we've worked with them, people that internally built that to improve it, and that's made a massive difference. Paul Marden: Excellent. James Hobbs: It's gone from being dirtier than a large majority of websites to being cleaner than most, which is great. We've pulled together some documentation for covering all sorts of areas from front end, back end development, content editing and so on, to educate people on how to build more sustainable websites. And some of the team members as well have built an Umbraco package, an open source package that you can install into Umbraco, and it will advise you in terms of the pages that you're making, whether they are good from a carbon footprint point of view or not. And we'll give you a rating, which is superb because it brings that whole thing in much closer to the end users who'll be making the pages. So that was a really nice piece of work. And on top of that, we do appear on things like this. Do webinars and talk at conferences and stuff. Paul Marden: Yeah, and I think Andy Evadale from Tangent is one of the members of the team. And honestly it was Andy who totally opened my eyes to this whole subject when I first started seeing him talk about it and giving some stats, and we'll talk a little more about those later on. There's definitely an impact that the team is having and it's really weird, isn't it? I mean, I don't want to geek out too much about Umbraco and the community, but there is something quite special about this commercial organisation that has open source software that gets given away for free, that collaborates with the community to build a product which is easy to use, pretty cool, really effective, but also sustainable as well. There's not many organisations that work in that way. James Hobbs: Yeah, it's unique and I love it. I think it's great. It just shows you it's possible to run a business and make money, but also have a really engaged community of passionate people and work together. I think it's brilliant. Paul Marden: Look, let's just take a step back from geeking out about Umbraco. Then I want to set the scene. Longtime listeners will know that Rubber Cheese run a visitor attraction website survey. We've done it for two years in a row. This year we simplified the survey down to make space for some more questions. And one of the key questions we've talked about is Sustainability. We are still just over the halfway point of the survey period, so there are still lots of responses coming in. But based on the data that we've got so far, we know that 72% of attractions in the current survey have got a sustainability policy, but only 12% of attractions have ever tested the CO2 emissions of their website. And we'll come to in a minute why we think the measurement and focusing on CO2 emissions in digital is important. Paul Marden: But whilst very few are actually testing their site, nearly half of all of the respondents so far have attempted something to reduce the CO2 emissions of their website. So there's clearly action going on, but it's not necessarily driving in a coherent direction because there's no clear benchmarking and target setting and retesting. So I think what I'd like to cover today is for us to understand that a little bit more, get under the skin of it a little bit, and then talk a little bit about how we can actually reduce the CO2 emissions, how can we actually make things different and why we might want to do it. Because it's more than just kind of the ethical, we all should be doing something. There were some real business benefits to it as well. My next question, without stating the bleeding obvious. Paul Marden: Okay, why do you think digital sustainability matters? I mean, the obvious answer is just because it does. But it's important, isn't it, as a contributor to global warming? James Hobbs: Yeah. So, I mean, there's lots of statistics knocking around, one of which I think it shows you the scale of the impact of the digital industry is. I think the total carbon footprint emissions of the digital industry is greater than global air traffic. And if you go and look on something like Flightradar or Skyscanner or whatever, and look at how many planes are in the air at any given moment in time, that's a pretty sobering statistic. There's lots of other ones as well, in terms of the amount of electricity that's being used, and water compared to even small countries like New Zealand. So we are generating a hell of a lot of carbon directly and indirectly, by doing all the things that we do. James Hobbs: And every time you hold up your phone and you load up Instagram or TikTok or download something, there's a massive disconnect cognitively, because it's just there and it just works and it doesn't feel like it's using up electricity and so on, but it is. There's a whole massive supply chain behind all of the lovely things we like to do on our devices that is hungry for electricity and generates pollution and that kind of thing. Paul Marden: Yeah. So my background was at British Airways and I was there for ten years. It really wasn't that hard to spot the fact that environmentally, that we have a challenging problem. Because when you stood on the end of Heathrow Runway, you can see what's coming out the back end of a 747 as it takes off. But I don't think I ever quite understood the impact of what I do now and how that's contributing more to CO2 emissions than what I was doing previously, which. Yeah, I just don't think there's an awareness of that more broadly. James Hobbs: No, yeah, I'd agree. And it's complicated. Paul Marden: In what way? James Hobbs: I guess it's complicated to quantify the carbon impact of the type of work that we do in the digital industry, because I guess there's what we're shipping to end users, which is one thing. But most modern websites and applications and stuff are built on a big tower of cloud services providers, and all of their equipment has to be manufactured which has a carbon impact. And rare earth metals need to be mined out of the grid. All of that stuff. There's a big supply chain backing all this stuff and we can influence some of that directly, but a large chunk of it we can't. So it makes choosing your suppliers quite important. Paul Marden: Yeah, absolutely. So if you're going down the road, if you accept the premise that this is a big contributor and making small gains on any of the stuff that is of interest to us and marketers who are owning websites attractions, I think for me, probably the first step is testing and trying to figure out where you are. Do you think that's a useful first step? Is that important as far as you're concerned, James? James Hobbs: I think it's important because with any sort of improvement, whether it's related to sustainability or not, I think quantifying where you are at the start and having a benchmark allows you to see whether you're going in the right direction or not. And improvement doesn't always go in one direction the whole time. There might be a two steps forward, one step back, depending on what you're doing. But I think without measuring where you are, and ideally regularly measuring your progress, it's hard to say what impact you've had and you might be going in the wrong direction and bumping up the wrong tree or whatever. So I think it's important. Paul Marden: Yeah, it's super important. And is it something that marketers themselves can do, or is this something that only a sustainability consultant can do, or is there somewhere in between? Is it the techy geeks that run the website that do this? Or is it a little bit of all of those things? James Hobbs: Well, that's a really good question. So I think this is still quite a new kind of industry. There are some tools out there that you can use to help you quantify the carbon impact of what you've got out there in the wild now. So the big one that most people talk about is websitecarbon.com, which is the website carbon calculator that was built by, I think a combination of an agency and some other organisations come up with an algorithm. It's obviously not going to be 100% accurate because every single website app, it's slightly different and so on. But as a consistent benchmark for where you are and a starting point for improvement, tools like that are really good. Ecograder is another one. Those offer non technical routes to using them. James Hobbs: So for the website carbon calculator, you just plunk a website address in hit go and it'll run off and tell you that's not very scalable. If you've got a 10,000 page website, or if you've got a large digital estate, there are also API level services that are provided that might make that easier to automate. But again, you then need someone who knows how to do that sort of thing, which raises the barrier to entry. I think what I would like to see is more and more vendors building carbon dashboards into their products and services so that the rest of us don't have to run around and build this stuff from scratch. Azure, for example, Microsoft's cloud platform, has a carbon dashboard that is scoped to your resources. That's really interesting and useful to see. James Hobbs: The stuff I mentioned about what we're doing with Umbraco and building a sustainability package, we're hoping to get that built into the core product. And again, the idea being that if you're a content editor or a marketer, you shouldn't have to know how to wire up APIs and do all this stuff, you should be able to see at a glance. Okay, well, that page I've just built actually is a little bit on the heavy side. Maybe I need to look at that. So I think the way to democratize it is to make it easier to do the right thing. Paul Marden: Yeah, absolutely. So these tools are giving you, they're giving you a grading? Yeah. So some of them are like a to f. I think it is for Website Carbon, Ecograder gives you a score out of 100. I think it is. Are there any advantages to one or the other? Or is it a good idea for people to use both of them and see the differences that the two different tools can give you? James Hobbs: I think it will come down to, well, for me anyway, I think using a tool in the first place is a step forward from what the vast majority of people are doing currently, which are not even thinking about it. So in many ways it doesnt really matter. I think it will depend on what people find easier to use. I think when people start to integrate this sort of sustainability measurements into their build pipelines, for example, release pipelines. That's where you will need to maybe think more carefully about the kind of data that you're interested in and what criteria you want to look at. Because, for example, at the moment, a lot of organisations who write software, hopefully their developers, will be writing some unit tests. And if the tests fail, then you don't deploy the website that should fail the build. James Hobbs: I think it would be good to move to a world where if your sustainability posture regresses and gets worse than similar things. There are other tools outside of those websites that we've been talking about, though. So there's an organisation called the Green Web Foundation, a nonprofit who do a lot of work in this space. And they've created a couple of tools. One's called CO2.js, which you can integrate directly into your website that can actually be a bit more accurate than the carbon stuff. And they've also built a tool called the Grid Intensity CLI. And without going into loads of horrible detail, what that is, essentially it knows when the electricity grid is at its most, what's the right word? At its most pollutant. When it's generating the most carbon. James Hobbs: So you can use that to figure out when to run background jobs or do lots of processing. You can do it when the grid is at its most renewable. So there's things like that as well. There's lots of options out there. You can go deep as you want. Paul Marden: Amazing. One thing that you just mentioned that I thought, oh, that's really interesting. I've never thought of that before, is the idea that you can drop a URL into Website Carbon or Ecograder and it will give you the score of that page. But actually, if you've got lots of pages on your website, you need to be testing across multiple pages. That should never occur to me before. James Hobbs: Yeah, because I think a lot of people plunk the homepage in and go, cool. It's a. I guess it's effort versus reward thing. No one's going, well, hopefully no one's going to spend time manually entering 10,000 website URL's into a tool like that. Not least because it would probably take the tool down. There are probably better ways of doing it than that. And also, homepages are typically quite different to the rest of a website. It serves a different purpose. So I think testing a representative portion of your digital services is probably the way to go. Paul Marden: Yeah, absolutely. I've been wondering recently whether buyers should be thinking about this as something that's part of the requirements of a new website. So if you're going out to tender and buying a new website, oftentimes you and I will both see requests for proposal that have accessibility requirements in them. But I genuinely don't remember a time that I've ever seen an RFP say, “You must achieve grade c or above on website carbon across the majority of the pages on the site.” And I think when buyers start to do that you'll begin to see agencies doing more of this sort of stuff. I think baking it into contracts will make a big difference. James Hobbs: Yeah, yeah and it's that kind of selective pressure isn't it? Clients start requiring this stuff, then agencies will have to step up. And it's unfortunate that might well be the catalyst but actually I don't care what the catalyst is as long as we're going in the right direction. Its the main thing really, which is lessening our impact. Yeah absolutely. But yeah that whole supply chain thing is huge. That's one way we can make a big impact is by mandating certain things. And there's actually a certification, a green software engineering certification. It's offered for free that developers or technical architects can go through to educate them a bit on green software engineering techniques and things like that. James Hobbs: And that's the kind of thing that hopefully in the future companies who are putting RFPs out might say, “We want your engineering team to be aware of green computing techniques” and so on and be able to prove it. Paul Marden: Yeah, I wouldn't be surprised as well that it gets legislated for as well. So in the same way as you know, public sector bodies have got to meet certain accessibility requirements. I would not be surprised if we enter a world soon where there's a statutory obligation for these things to be done in a sustainable way as well. James Hobbs: Yeah. Paul Marden: So getting your act together now is a really good thing to do because there's going to be less work later on when you've got no choice but to do it. James Hobbs: Exactly. Get ahead of the game now. Paul Marden: So we've made the case, people have bought into it, they're going to go and do some testing and they realise that they've got a smelly, polluting, rich website. What can they do next? How can your average head of marketing, head of digital influence their website to get better? James Hobbs: Yeah. Okay, so this is where I think there's a really nice angle here. We did talk about this earlier on, but there is a fairly close link between the things that will make doing the things that will make your website, your digital services more sustainable and kind of KPI's and metrics that will probably make it more commercially successful as well, depending on what you're doing, with a bunch of caveats that I won't go into. So, for example, sustainable websites are typically lightweight, they're fast, they're optimised for getting the right things in front of the user as quickly as possible, which can include everything from content delivery networks to optimising images to a whole host of stuff. Doing all of those things will also typically positively impact your search engine optimisation, positively impact your conversion. James Hobbs: Because if you look at Google's guidance, Lighthouse guidance, the different things it looks at and so on, it's very clear that fast, relevant websites are what get prioritised and what Google's looking for. Fast, relevant websites that are served from locations close to the user are also likely to be sustainable. So there is a link there. And what that means is there's a built in business case for doing the sustainability stuff. James Hobbs: So if you've got a hard nosed suite of executives who couldn't care less about the planet, not that I'm saying that's what everyone's like, but, you know, the commercial world that we live in, it's a hell of a lot easier to sell this stuff in by saying, “You know what as well, like we can do an MVP or a pilot and we're confident that we might be able to improve conversion by 0.1%, 0.5%”, whatever it might be. It's also typically a good way to save money by being smarter about what you're computing and where and when and using some of those tools that I've talked about, you can save yourself potentially a bunch of money as a business, which again, is a commercial win. James Hobbs: So I think whilst the ethical side of it is really important, and, you know, none of us want to be boiling to death in 50 years time because we've ruined the planet. Making small changes in digital can have a massive impact because the amount of people that are using them. And I think it's easier to sell in because of the commercial. Paul Marden: Yeah, absolutely. So I'm guessing there's stuff that you can do at key stages in the design and development of a site. So what are the things that people should be thinking about during the design of the site that could make it more sustainable? James Hobbs: So, okay, so that's a really good question. So this is a huge topic. So I can give you some examples of the kind of things you should be thinking about. So. And I guess we could divide them up into two sections. So when we're designing a website. There's how it looks and how the user experience work. There's also the technical design. As with anything, the further, the earlier you start thinking about this kind of stuff, the easier it is. Crowbarring in. It's a bit like accessibility, you know this, try and crowbar it in the last week of the project, it's not going to work. So from a design point of view, and some of this stuff is difficult to quantify its impact in detail, but things like not having massive 4k full bleed videos at the top of your webpage. James Hobbs: So being very careful and intelligent use of things like that, because they are large, they have to be transferred from wherever you're serving them from to the user. There's a big energy cost associated with that, not using loads and loads of external dependencies on your web pages. And that could be anything from fonts to JavaScript libraries to the vast myriad of tools that are being used. The more things you're throwing down the pipe to your end user, especially if your hosting infrastructure is not set up in a distributed way, the more energy intensive that thing is. You can even go as far as looking at the color choices that you're using. So certain darker themes are typically less energy intensive. Yeah, because of how OLED screens and modern screens work. Again, very hard to quantify. James Hobbs: And then we go down the rabbit hole of yeah, but where does the electricity that charges my phone come from? And you try and quantify all that stuff, it gets very head explodey. But there are things you can do in that sense. Some of them are easier to quantify than others. The weight of the page is a very easy thing to measure. If you keep that low, it will be easier to cache, it will load quicker for users, it will better for SEO, and faster pages tend to have better conversion. James Hobbs: And that works whether you're selling things from an e commerce point of view or you're trying to register interest, whatever it might be, from a technical angle, I think one of the most impactful things you can do, beyond making sure that your code is optimised and is running at the right times, at the right place, is simply to consider using a Content Delivery Network. And for your listeners who aren't familiar with a content delivery network, a CDN is something that all of us have interacted with at one point or another, probably without realising in the traditional way of serving or having a website, you've got some service somewhere, in a data centre somewhere. When someone types your website address in, it goes and fetches that information from the web server and back comes a web page in the simplest sense. James Hobbs: Now, if your website servers live in Amsterdam and your users on the west coast of America, that's a big old trip for that information to come back and forth. And it's got to go through lots of different hops, uses up lots of energy. A content delivery network is basically lots and lots of servers dotted all over the planet, in all of the major cities and things like that can keep a copy of your website. So that if someone from the west coast of America says, “Oh, I'm really interested in looking at this website,” types the address in, they get the copy from a server that might be 1020, 50 miles away from them, instead of several thousand across an ocean. James Hobbs: So it loads quicker for the user, which is great from a user experience, SEO, all that stuff I talked about, but it's also great from an energy point of view, because it's coming from somewhere nearby and it's not having to bounce around the planet. That's one thing that you could do that will make a massive and immediate impact commercially and from a sustainability point of view. Paul Marden: So you get those kind of performance improvement for the people all the way around the world accessing the site, but it's going to take load off of the server itself, so you might need less powerful servers running. One of the big issues that attraction websites have got is that it's such a cyclical market. The people that, you know,James Hobbs: Spiky.Paul Marden: Exactly when the Christmas meet Santa train is released at an attraction, or the traffic to the website is going to peak. If you can keep some of that traffic off of the web server by using that Content Delivery Network instead, you're going to be able to withstand those really peak times on the website without having to spend lots and lots of money on improving the resilience of the service. So it really is a win win win, isn't it? James Hobbs: I think so. And also it can help potentially avoid things like the dreaded queue where you log on to a website that's busy and it sticks you in a queue and you're 41,317th queue or whatever. Exactly like you say. If you can leverage this tech to take the load off your back end systems and I, you'll be delivering a better user experience. Paul Marden: One of the measures that I know a lot of the algorithms that are assessing CO2 emissions look at is the type of hosting that you use. So they talk about green hosting. What is green hosting? And is all green hosting the same? James Hobbs: No. So yeah, again, this is a big topic. So I guess hosting generally runs the spectrum all the way from kind of one boutique sort of providers who can set up VMS or private servers or whatever all the way through to the big goliaths of the Internet, the AWS and Azure and so on and everything in between. So green hosting is broadly hosting that is carbon neutral, powered by renewables, that sort of thing. So in theory shouldn't be pumping more pollutants into our atmosphere than it's saving. So if we look at the big cloud providers initially, so they've all made some commitments in terms of improving their sustainability posture. And this is really good because when one does it, the other one has to do it too. And obviously there's Google Cloud platform as well and they're doing similar sorts of things. James Hobbs: But it's almost this, I like the competitive angle of this because all it means is the sustainability posture of all of them will get better quicker. So it's good. So for example, I'll try and do this off the top of my head, you should check yourselves. But Azure and AWS and Google all have some pages that talk about their commitments and primarily they're focused on carbon neutrality and using renewable electricity. Aws have done a good job of that. So in certain AWS regions the year before last, they were completely 100% renewable powered, which is brilliant. Paul Marden: Really. James Hobbs: Yes. Not everywhere. Azure are going down a similar path and they've made the same commitment in terms of the year when they're going to hit renewable powered everything. They've also made commitments to water positivity. Enormous amounts of water are used during the operation of data centers and there are a lot of these data centres. So they've made commitments I think by 2035 or 2040 please double check to be net water positive, which is great. And the other thing that people don't think about, and this is I guess the supply chain thing I was talking about earlier, all those servers got rare metals in them. They've got all kinds of stuff in them thats been dug out of the ground, often in areas where there's a lot going on from a human point of view. James Hobbs: So Amazon, AWS, Google, et cetera, they're looking at that angle too. How can they keep servers in commission for longer so they don't need to be replaced as often? Where are they getting their materials from, et cetera, all that kind of stuff, because they're not just a computing company know they're invested in the hardware and getting this stuff out of the ground and manufacturing it and all the rest of it's a very big operation. So that's something we can't influence beyond pressuring them as consumers, but it is something that they're doing something about, which is great. Paul Marden: Yeah, absolutely. And if we go back to that point I made earlier on, buyers are in control of this. If they are choosing to include that in their contracts to buy new web services, that it needs to be green by offsetting or green by using 100% renewable power, then that drives change, doesn't it? Procurement managers drive change through that kind of thing. James Hobbs: Yeah, absolutely. And just one final point on the greenhosting the Green Web foundation, who I mentioned earlier, the nonprofit who work in this space, they maintain a list of green web hosts. So hosts that are known to be green that you can use without having to worry too much. So it's worth looking at that as well. And it's a kind of impartial list. Paul Marden: Excellent. Do you think this is a story that attraction should be telling? So they're going to be, we're hoping that people are going to become energised by this and they're going to want to go on a digital sustainability journey. Do you think that is that something that they could be shouting about? James Hobbs: I think so, if done in the right way. Obviously, you've got to be careful of the sort of, we planted some trees and now everything's fine, because I don't think that's necessarily the case. But I think talking about it in the right way, which is we know we're not perfect, but we're doing something about it, and this is our plan, and being transparent about it, I think, is a good thing. I think it will also foster competition between different attractions, and everyone's a winner, really, because it will make everyone more sustainable. Paul Marden:  Yeah. James Hobbs: And yeah, I don't see why you shouldn't talk about it. I think its something thats important. And to your point earlier about consumers being able to influence some of this stuff, I really, truly hope that the generation of youngsters that are coming up now are going to be more hyper aware of this sort of thing, and they're going to care a lot more because it's likely to affect them more than it will us. So I would like to think that they will be selecting products, services, attractions, whatever it might be that can demonstrate that they're actually doing something to lessen the impact of their operations. James Hobbs: I've got two relatively young children, and I can already see them asking questions and being interested in this kind of stuff in a way that wouldn't have occurred to me when I was a kid, just didn't think about it. I cant change that. But what we can do is try and improve the world that were going to be leaving to the the youngs.Paul Marden: Yeah, absolutely. So, one last question for you. Is there anything. Is there anything happening in this space that you think is really cool and interesting to think about? James Hobbs: That's a good question. I mean, like, I hope this isn't a non answer. I think the thing. The thing that is exciting me most is that more and more people are talking about this stuff. More and more people are asking questions about this stuff and I've done a lot of talks and webinars and things on this topic and the thing that really makes me feel positive and excited about it is that nearly all of them afterwards, people come up to you, they message you and say, “I just didn't realise.” The fact that we're able to raise awareness is brilliant because we can start to build up a bit of momentum. I think the thing that. I think I mentioned it earlier, products and services, building this sort of stuff into their platforms in terms of helping users use their services more efficiently, I think that's the area that I'm most excited about, because otherwise it's people kind of hacking stuff together. I think it should be a first class part of any solution, really is like, carbon impact of what I'm doing. That's what I'm probably most keen to see more of. Paul Marden: James, thank you. One last thing. We always ask our guests for a book recommendation and you've already said you're an avid reader, so no pressure, but I'm quite excited to hear about this one. James Hobbs: Well, there's two and I thought I'd just make the decision when you asked me the question about which one to recommend. So I'm going to go with my legitimately favourite book, which is the Player of Games by Iain M Banks. It's part of the culture series of novels and I'm a bit upset because Elon Musk has been talking about it. I feel like he's tarnished it slightly. A magnificent series of novels. I remember finishing the 10th one and sadly, the author died a while ago and I genuinely felt slightly bereft that there weren't going to be any more of them. It's a brilliant book. It's exciting. Yeah, it's exciting. It's so creative and inventive. It makes you think differently about things. It's definitely not one for children. James Hobbs: You know, there's a lot of violence and all kinds of other things in there. But it's a fascinating book. All of his books are fascinating. My favourite author. So if you're going to, if you think about getting into his books and specifically the culture novels, that's a great point to jump in at. It's accessible and it's absolutely brilliant. I love it. Paul Marden: That's quite the recommendation. So, listeners, if you want to get into this culture series of books, then when we post the show notice on X, get over there and retweet the message and say, “I want James's book.” And the first person to do that will get that sent to them. James, this has been brilliant. There's a couple of takeaways I want people to go and think about, one from me, which is go and test your site and then jump into the Rubber Cheese website survey. Paul Marden: Go to rubbercheese.com/survey, tell us all about your attractions website and one of those questions will be about have you tested the CO2 emissions of your site and have you done anything about it? The more we understand what the sector is doing, then the more we can understand how we can all help and improve things. Paul Marden: James, you had one idea of a place where people could go and find out more about this sort of stuff. James Hobbs: Yeah, I mean, there's some organisations that I mentioned. So the Green Web Foundation is one that's got lots of interesting material on there, both tools that they've made, but also they fund research in this space, which is really important. It should be treated like a specific discipline. I suppose they're doing some great stuff there. There's the Green Software foundation, which confusingly similar name, doing some good work in this space. There's also lots of interesting groups on discord forums that are out there. I guess my main message would be we're all learning more about this field. No one has all the answers, but there are organisations out there that you can come and speak to that can help you understand where you are currently. James Hobbs: And I definitely encourage you guys to fill in the surveys, Paul said, because the more information that we've got, you know, the better we can understand where things are. Paul Marden: James, this has been a lot of fun and really interesting.

Für diese Folge von Shift Happens haben Miriam und Léa einen neuen Titelsong generiert – mit einem neuen KI-Tool namens Udio. Wie auch bei anderen KI-Tools stellt sich für sie die Frage, wo beim Einsatz der Anwendungen die Grenzen von Ethik und Kunst verlaufen. Zum Glück hat ABBAs Björn Ulvaeus eine Antwort für sie. Außerdem sprechen die beiden über den weitestgehend verborgenen Stromverbrauch von Software und stellen fest, dass einige Websites viel mehr Strom verbrauchen als andere. Noch viel höher ist der Energieverbrauch von KI-Sprachmodellen. Miriam und Léa erklären, inwiefern Green Software und kleinere Spezialmodelle eine Lösung darstellen könnten. Zuletzt führt Miriam Léa mit einer neuen und geschickt platzierten Art der Werbung an der Nase herum – die ausnahmsweise nicht die Augen und Ohren anspricht, sondern den Geruchssinn.
