Green IO Newsletter - December 2025
Building a greener digital world, one byte at a time
Hello responsible technologist!
The last newsletter of the year is often an opportunity for some introspection. After 5 conferences and 20 podcast episodes, I realized over this year how I was obsessed with waste. Of course physical waste has always been at the top of my mind, but the advent of the attention economy has shifted my attention toward the time we spend doing things. I reckon that some listeners have spent more than a day listening to the podcast this year, and some attendees several days of their life (yes we do have technologists attending several Green IO conferences per year!). I now better understand why I am focusing so much on the ROTI (Return On Time Invested). The last edition of Green IO Paris was no exception. Of course, just gathering ~800 responsible technologists to meet and mingle is an achievement in its own right, and the same goes with offering almost 20 European NGOs a room to work together for an entire day. Many thanks to all speakers, MCs, volunteers, sponsors and participants for making it such as success. But, what about the talks ? Did people truly get new insights? Did perspectives change thanks to feedback? Were there benefits from having a majority of non-French speakers? This is why I was asking seasoned green IT experts all around the venue “how is the conference going for you so far?”, and I was relieved that the feedback went beyond the usual politeness and was illustrated by clear examples.
