Green IO Newsletter - May 2025
Building a greener digital world, one byte at a time
Hello responsible technologist!
Welcome to our US-based and Canada-based new readers
Welcome to all the 163 new readers who attended Green IO New York 3 weeks ago and wanted to stay informed about IT & Sustainability. In case of mistake / no time / 2nd thought / etc. please unsubscribe here! And no hard feelings. 🙂
And if you prefer to try out our Monthly newsletter first, no worries, the unsubscribe button is also at the end.

Green IO New York, ICT4S, GreenForum Berlin, Green IO Munich, … Eventually responsible technologists have more and more places to meet, learn, share, and grow our community. A world of opportunities and … frustrations because many of us cannot attend all these great conferences. This is why, starting this month, we created a new section in our newsletter “Couldn’t attend?… we’ve got it covered for you” where members of the Green IO community share their main takeways of a conference. Let us know what you think about the initiative, and feel free to reach out to us if you attend a conference and want to contribute.

# Couldn’t attend?… we’ve got it covered for you
# Couldn’t attend Green IO New York?… Nolwenn got it covered for you
Green IO New York was nothing short of energizing — a gathering filled with insight, candor, and real-world impact. Our speakers (from veterans to trailblazers) didn’t just share best practices, strategies, and tools — they brought vulnerability, hard-won lessons, and truth about the real challenges our community is facing. Sometimes with humor 😀. Below are my main takeaways. For additional details, check the presentations on the Green IO New York website and check the conference booklet for an overview.
🌱 From Awareness to Action: Operationalizing Sustainable Tech
Sustainability is not just an ethical concern — it's a practical, financial, and strategic imperative. Moving from intention to implementation requires measurable actions, tools, and organizational buy-in.
GreenOps as a repeatable operational model (Thoughtworks, Mastercard)
Learn–Measure–Reduce frameworks (Green Software Foundation)
Tools like Cloud Carbon Footprint, Electricity Maps, Boavizta, CodeCarbon, AI Energy Score, Ecograder and AIWattch <span">are useful to raise awareness of compute intensity, track and reduce emissions.
"Sustainability isn’t a checklist — it’s a mindset embedded in decisions and systems."

# Couldn’t attend GreenTech Festival Berlin?… Wilco got it covered for you
If I would tell you that Green Tech, Formula 1, and sustainability have something in common, you would probably think I am lying or just plain nuts. And honestly, I would not blame you. But stay with me, because that connection is real, and it is where the story of the GreenTech Festival begins.

# Listen… We’re all ears
EV comes up trumps again with E107 on cloud infrastructure, efficiency & sustainability, and E108 on hardware standards. And as our energy systems become more distributed, electrified, and digitally connected, this episode from The Inevitable podcast discusses how to protect critical infrastructure from cyber attacks, resonating nicely with our E35 (with Mary Prokhorova and Michael J.Oghia) which explored the intricate relationship between cyber security and environmental sustainability.
# Read… Our coffee-break reading this month
The excellent MIT Technology Review supertopic series entitled Power Hungry: AI and our energy future details the state of AI's energy and resource usage, where it is now, where it is headed in the years to come. A must-read for anyone working in Green IT.
The much awaited V2 of the Climate Product Management Playbook dropped earlier this month, containing case studies and best practices organized in 6 chapters (including the addition of an AI-specific chapter). Exode released ‘Green IT, Purchasing Guide’ by Janne Kalliola, which details procurement issues- software, hardware, services- plus the importance of working with suppliers, reporting and much more. Listen to Janne in our E40 too, where he talks about green software, and how to trigger positive actions in the Tech sector.
And finally, a huge collaborative win, as the GSF working group have published their Green AI Position Paper, which defines a shared understanding of what Green AI means and how we can apply it in practice.
# Tools… Skill-up for a sustainable future
Claiming ‘medium is the new large’, the French Mistral Medium 3 has been released, pushing efficiency and usability of language models even further - but watch out for a ‘large’ release later this year… And check out the new suite of Wave Accessibility Tools featuring useful panels and icons aims to increase accessibility of any web content. Plus, for all you budding researchers out there, the Digital Humanities Climate Coalition has just released a toolkit aimed at making research practices more environmentally responsible (you can also get involved through Github.)
# Participate… One byte at a time
If you are a startup needing some advice on how to navigate the complex conundrum of growth, innovation and sustainability, then Remission and SparkIT’s forthcoming publication might be just what you need - help shape the guide and get the heads-up on its publication here.
