Green IO

Sasha Luccioni, responsible AI researcher and Sustainable AI Group co‑founder. Boris Gamazaychikov, sustainability and data center economics expert and co‑founder of Sustainable AI Group. They trace the money driving AI infrastructure. They unpack data center margins, GPU replacement cycles, grid constraints and why enterprise demand could force transparency and efficiency in AI supply chains.

Jeremy Tamanini, a researcher and consultant on applied AI for sustainability and contributor to IEEE environmental indicators, explores where AI genuinely helps and where claims fall short. He discusses AI for carbon accounting, satellite computer vision for Scope 3 visibility and carbon credits, the trade-offs between efficiency gains and real climate outcomes, and when simpler fixes beat complex models.

Do software engineers still have the choice of not using AI? The numbers speak volumes and the short answer is ...no. For the environmentally-aware developer, this is a daily dilemma. In this episode of Green IO, Gaël is joined by Natasha Ann Lum, co-founder of the RagTech podcast and MC at Green IO Singapore 2026. She practices AI-assisted coding every day. But here’s the catch - she’s doing so by ‘embracing the discomfort of AI’, warts and all. That means jumping in, finding the relevant use cases for AI in her daily workflow, and mitigating its costs.Natasha’s approach comes from a place of advocacy that many other responsible technologists can relate to; data sovereignty, minimising environmental impacts and finding ways to speak truth to power. And behind it all is a decision-making framework that threads everything together. Gaël and Natasha dive into:▪️The need to push for decentralised technology▪️Her systematic approach to ‘intentional AI’▪️Challenges facing the broader tech sector▪️How we aren’t powerless to enact change▪️Natasha’s personal daily tech stackAnd much, much more.❤️ Like and subscribe so that you never miss an episode.---Connect with Natasha Ann Lum:▪️LinkedIn: https://www.linkedin.com/in/natashaannn/▪️Podcast: https://www.youtube.com/@ragTechDev Connect with Gaël and Green IO:▪️Green IO Website: https://greenio.tech▪️Green IO Slack: https://greenio-podcast.slack.com▪️Green IO YouTube: https://www.youtube.com/@greenio877 ▪️Gaël’s website: https://www.gaelduez.com---Referenced in this episode:▪️Green IO Singapore 2026: https://greenio.tech/conference/18/singapore-2026-april ▪️Pragmatic Engineer's 2026 study: https://newsletter.pragmaticengineer.com/p/ai-tooling-2026 ▪️AI Energy Score: https://huggingface.co/AIEnergyScore ▪️Electricity Maps: https://www.electricitymaps.com/---🎁 Want to accurately measure your team’s environmental impact?

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?
