Gauthier Roussilhe, researcher and Head of R&D at Hubblo focused on digital sustainability, breaks down why IT-for-green claims need careful reading. He explores remote work’s modest climate gains, the surprising limits of office energy savings, dynamic line rating benefits, rebound effects, and why context shapes whether tech truly helps the transition.

Does it really make sense to measure carbon per gigabyte?Or should we be adapting our sustainability metrics to focus on more meaningful elements of the digital streaming supply chain?Here to discuss many common misconceptions around network energy consumption, is Dom Robinson. Dom is the founder and CSO at Greening of Streaming, an organisation brining together tech providers and media companies with the aim of reducing our environmental impact. He’s steadfast in his belief that we can better engineer and design digital networks to achieve that goal, without hindering speeds, availability or the overall user experience.From radio to streaming, Dom provides an easy to follow, insider’s guide to the different types of digital networks, and how they consume energy. He also shares insights on how we can better scale our networks and why Big Tech’s digital sustainability efforts are often profit-driven.Gaël and Dom also discuss:◼️ Retiring the mantra of ‘use less data to save the planet’◼️ Do modern networks really use less power?◼️ How much impact will ‘AI’ have on networks?◼️ Attribution model vs consequential analysis◼️ More efficient network design And much, much more.❤️ Like and subscribe so you never miss an episode.---Connect with Dom Robinson:◼️ LinkedIn: https://www.linkedin.com/in/domrobinson/ Connect with Gaël and Green IO:◼️ Website: https://greenio.tech ◼️ YouTube: Green IO ◼️ Slack: https://greenio-podcast.slack.com◼️ Gaël: https://www.gaelduez.com---Referenced in this episode:◼️ Paper: Position Paper on AI in Streaming Sustainability ◼️ Article: The carbon footprint of streaming video: fact-checking the headlines – Analysis - IEA ◼️ Article: Factcheck: What is the carbon footprint of streaming video on Netflix? - Carbon Brief ◼️ Article: The Shift Project a-t-il vraiment surestimé l’empreinte carbone de la vidéo en ligne ? - The Shift Project ◼️ Interview: The Impact of AI on the Network ◼️ Talk: The Internet is getting emptier; that's a sustainability problem by Romain Jacob (Green IO Paris 2025)---🎁 Want to accurately measure your team’s environmental impact?

We’re facing an existential environmental threat - but is there enough time to fight back against the increasing momentum of tech-related planetary collapse? That’s the 8 billion-person question. And here to help us answer it is a returning Gerry McGovern, back to share everything he’s learned during the making of his new book, ‘99th Day: A Warning About Technology’. Throughout this insightful discussion, Gaël and Gerry wrestle with a central thought: Does technological advancement automatically mean societal and environmental decline?The pair discuss Gerry’s unique writing style, his journey from rock’n’rolla to technology journalist, how he found his calling and hopes for the future. Gerry McGovern and Gaël also dive into:Is digital still a positive transformer for the environment?Lessons we can learn from indigenous societiesIs ‘AI’ a useful tool, or a crude chainsaw?The second order effects of miningWhat is the ‘Growth Death Cult’?Can we turn it all around? And much, much more. ❤️ Like and subscribe so you never miss an episode.---Connect with Gerry McGovern:◼️ Website: Home Connect with Gaël and Green IO:◼️ Website: https://greenio.tech ◼️ YouTube: Green IO ◼️ Slack: https://greenio-podcast.slack.com◼️ Gaël: https://www.gaelduez.com---Referenced in this episode:◼️ Book: 99th Day: A Warning About Technology ◼️ Book : World Wide Waste ◼️ Article: Doughnut | Kate Raworth ◼️ Study: (PDF) The information catastrophe ---🎁 Want to accurately measure your team’s environmental impact?

Sustainability data isn’t just for the marketing department - it’s becoming an increasingly important element for regulatory compliance.So how easy is it for your business to report and that information?On today’s special episode (recorded live at Green IO Paris), Gaël is joined by Chris Adams, Director of Tech and Policy at the Green Web Foundation. He’s here to tell us about carbon.txt, a new tool from the GWF that aims to make sustainability data transparent, easy to share and verify. Hopefully this can spark few conversations around new norms for digital sustainability. Gaël and Chris also discuss:What it now means to be a responsible technologistWhy data transparency matters for sustainabilityIncentivising Big Tech to change (for good)The thinking behind Carbon.txtAnd much, much more.If you’re listening to this, be sure to check out the full video version on Spotify or YouTube, at the links below.❤️ Like and subscribe so that you never miss an episode.📧 Each month our readers get carefully curated news on digital sustainability, packed with exclusive Green IO content.

Cathleen Berger, a sustainability researcher and former head of sustainability at Mozilla, dives deep into Big Tech's emissions reporting. She discusses why accurate data is crucial and how many companies misreport figures to downplay their emissions. The conversation touches on the challenges posed by geopolitical factors and AI hype, and critiques methods used to obscure true impacts, especially around scope 3 emissions. Cathleen highlights companies that excel in transparency, like Apple, while revealing the pitfalls of others, including Microsoft and Meta.

Mark Butcher, an expert in green operations and sustainable IT, and Wilco Burggraaf, a Dutch advocate for green software, explore the environmental impact of Generative AI. They debate the validity of recent studies, including Google's Gemini report, and discuss how to prevent waste in GenAI operations. Mark raises concerns about the social implications of AI, while Wilco emphasizes the importance of sustainable coding practices. Both highlight the need for actionable strategies to reduce GenAI's footprint and ensure better accountability in environmental reporting.

The potential impact of Artificial Intelligence on our worsening climate crisis is certainly a hot topic, pardon the pun. Fortunately, we have an expert on today’s show to help us make sense of it all. Iuna Tsyrulneva is one of the leading voices in AI and sustainability. Well versed on both topics, Iuna holds a PhD in materials science, and works at Earth Observatory of Singapore with an interdisciplinary approach. She’s full of interesting insights, and brings a dynamic approach to thinking about the larger issue.For example, did you know that saying “thank you” after every prompt actually contributes to AI energy usage? And they say kindness costs nothing…As you’ll hear from Iuna, optimisation is the key to affecting sustainability in Artificial Intelligence. And that goes beyond ‘clean code’. Throughout our conversation, Iuna unpacks the end-to-end scope of optimisation, or what she calls her ‘four pillars’ of sustainable AI, that being algorithmic, hardware, data center and usage optimisation. In this episode, Gaël and Iuna also discuss:Sustainable AI vs AI for SustainabilityHow (if at all) can we mitigate Jevons paradox?Tackling the financial incentive vs sustainability in AIWhy she’s optimistic about the future of sustainable AIUsing more energy efficient languages to build next-gen AILeveraging open-source frameworks to lower resource costsPractical tips on how to make AI models more energy efficientAnd much more!❤️ Like and subscribe so that you never miss an episode.📧 Each month our readers get carefully curated news on digital sustainability, packed with exclusive Green IO content.
