Along these lines, roughly a decade ago I filed a patent for selective routing to data centers for purposes of power control and environmental impact [1]. While I've left Juniper since, if there were interest, they may be willing to assign the IPR to IETF if asked nicely.
That said, this patent somewhat missed the claim. What's really needed is power-based routing in general (not just to data centers), whereby how green the power is matters. Of course, getting routers to accurately testify the greeness of their power source could be difficult...

I think it is an interesting topic and very much on topic for us to think about. And a topic where potential savings could be significant. IT is a huge energy consumer (as well as a producer of short-lived gadgets). IT also has the potential to help optimise many non-IT processes, and therefore directly reduce energy consumption and waste.
But of course this is also complex topic and not one where only IETF or only standards help. And a topic where continuous improvements in compute and comms are often offset by more high res videos and ever growing software packages (as well as auto-play and zillions of adverts, placed on my screen after way too much ML analysis).
I’d be eager to work on this, assuming we can come up with proposals that can have an impact.
