Modeling Indirect Effects of Remote Work

The sustainability story of IT is deeper than you realise.

And in order for us to find the real answers, we need to read between the lines.

On today’s episode of Green IO, Gaël is joined by Gauthier Roussilhe, an out-of-the-box thinker, researcher and head of R&D at Hubblo. Gauthier takes us on a deep dive into the findings of one of his latest environmental studies… and explains why we need to embrace a counter-intuitive approach when looking at the data.

During this conversation, Gaël and Gauthier also talk about:
▪️ Unpacking the environmental impact of remote work
▪️ Tracing the origins of IT of Green (IOG)
▪️ The hidden data we’re overlooking
▪️ The rebound effect
▪️ Why context is key

And much, much more.
