Moore’s law is dead! Long live Eroom’s law! This provocative statement from Tristan Nitot highlights the pivotal role of software engineers in our journey as an industry toward a sustainable and more frugal digital world. The majority of our old devices, from smartphones to desktop, still work. How come that we waste such a massive gathering of precious resources such as minerals, energy, water and even our human time which we use to manufacture and maintain them? What should we do to break the trend of electronic waste and the ever-increasing footprint of the IT sector on our physical world? Gael Duez sat down with Tristan Nitot to start answering these questions in this Green IO episode where we covered: ⚖️ Why Wirth’s law matters more than Moore’s law 🗑️ How the Auvergnat cultural aversion for waste accelerated the birth of the Eroom’s law 🔎 How to find (sustainability) weakness in your software, 🐍 Why Python is not (always) guilty of being resource hungry and how to embrace a wise use of alternative libraries such as Polars, ✨The real ROII of using AI to optimize software.

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: 💪 How two motivated engineers can start a movement in a 4K employees company, 🔎 Tracking the cultural change signals, 🔄 Bringing carbon awareness in existing process rather than creating new ones, 🎓🛠️ Making Community of Practices & tooling working hands in hands, 📊 How Data management primes over UI when deciding to build a carbon dashboard, 🎙️ Why listening to Green IO actually helps (not Gaël saying 😉).

3 billion gamers worldwide, billions of devices, terabytes of data streamed, the gaming industry comes with pretty big numbers starting with its $455 billion sales in 2023. Is its environmental footprint as big? (Not) fun fact, not a single executive in this sector could answer the question. A new non-profit initiative, the Sustainable Gaming Alliance, is trying to get these numbers right and to equip the industry with the right framework. Its Managing Director, Maria Wagner, and its Research and Standard lead, Dr Benjamin Abraham joined this Green IO episode where great insights were shared on: 👿 The periodic table of torture for gaming device, 🖼️ The Gaming industry dependency on graphics to boost its sales 🕹️ Why “this game is beautiful” should be replaced as a praise by “this game is so enjoyable” 📋 Why GHG protocol is not adapted to the gaming industry 🌋 How to shake up a multi-billions industry in 10 weeks ? 🔄 Why the project mode in the game industry - and elsewhere? - doesn’t help a GreenOps culture to flourish 😴 Energy consumption at idle state

They both went to this job interview to hone their skills, and got a dream job at Microsoft! In its fast-growing and AI-pioneered Azure division.

How do we tackle the Green IT blind spot? 🏞️ In many big corporations, IT is never number one, number two, even number three for GHG emission sources (and other environmental factors). But everyone working in the digital sustainability sector knows that, actually, little streams make big rivers with the digital sector accouting for around 4% of global emissions. 📏 In this episode we explore a very concrete case of measuring IT footprint in a massive corporation: ABB Motion with Thomas Mosser (ABB) and Fiona Leibundgut (SparkIT Consulting). How to kick start, how to leverage the Resilio tool which they chose, how to scale, etc. And the insights shared can be used in smaller organisations as well!

0.9g of CO2e. It’s pretty ridiculous when you think about it. According, the French SRI association this is the carbon footprint for a 10K prints digital campaign with a 200k image. So not a big deal? Not that simple because we’re talking about volumes in trillions per day here. So maybe it’s a good idea to dive a little deeper on the environmental impact of digital marketing after all. Hence we brought 2 experts in AdTech with a soft spot for Sustainability: Diarmuid Gill is Criteo’s CTO since 2019 and has been in Digital Advertising for more than 15 years. Audrey Danthony has also a long career in AdTech, she started her first company, Oxeva, during the dot-com boom when she was still a student at engineering school. And 2 years ago she pivoted and founded with 2 partners Impact+ with the aim of reducing Greenhouse Gas emissions in digital advertising. ❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode! 📧 Once a month, we deliver carefully curated news on digital sustainability packed with exclusive Green IO contents in your mailbox, subscribe to the Green IO newsletter here.
