    AI & Sustainability: follow the money! with Boris Gamazaychikov and Sasha Luccioni | #79

    What if the biggest barrier to sustainable AI isn't carbon — it's the economics? ... again! On today's episode of Green IO, Gaël is joined by Boris Gamazaychikov and Sasha Luccioni, two leading voices at the intersection of AI, energy, and sustainability, who recently left their roles at major tech companies to tackle these questions head-on. Together they unpack the financial architecture driving the AI infrastructure boom — and why understanding the money is the key to understanding everything else. From the jaw-dropping revenue margins of hyperscale data centres to the hidden lifecycle of GPU hardware, Boris and Sasha make a compelling case that the AI industry is entering a decisive new phase — one where enterprises are finally gaining the leverage to demand transparency, efficiency, and genuine accountability from the companies selling them AI.

    Can AI be applied for Sustainability? It’s complicated… with Jeremy Tamanini | #78

    Is AI genuinely helping us build a more sustainable world — or are we papering over inconvenient trade-offs with a shiny new tool? On today's episode of Green IO, Gaël is joined by Jeremy Tamanini, a researcher and consultant who has spent years investigating applied AI for sustainability use cases. Jeremy brings a refreshingly grounded perspective to one of the most hyped conversations in tech: can AI actually move the needle on environmental and social outcomes, or does the framing of "AI for good" obscure more than it reveals? Together, Gaël and Jeremy resist the temptation of easy answers. Rather than cheerleading or catastrophising, they dig into concrete examples — from carbon accounting platforms embedding AI to cut compliance workloads, to satellite imagery married with machine learning to illuminate Scope 3 emissions that would otherwise remain invisible. The conversation is a careful, honest attempt to map where the evidence points, where it is still missing, and why that distinction matters enormously.

    The dilemma of using AI for sustainable software engineers, with Natasha Ann Lum | #77

    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.

    Streaming, Networks and Sustainability, with Dom Robinson | #74

    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.

    #73 Gerry McGovern vs the Growth Death Cult

    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 societies Is ‘AI’ a useful tool, or a crude chainsaw? The second order effects of mining What is the ‘Growth Death Cult’? Can we turn it all around? And much, much more. ❤️ Like and subscribe so you never miss an episode.
