Thank you for making this proposal. I think making the network carbon neutral is a great first step. We have been dedicated to a similar cause at earthwallet.io (the first self custody wallet for the IC), and recently partnered with klimadao (the largest crypto carbon credit dao) to make this a reality by offering users a way to purchase carbon credits to offset their txs.
What I would suggest is the IC does something similar to Polygon, where we can do a shared analysis on the network usage, then commit to purchasing enough klimadao credits to make the network carbon neutral.
As we proposed earlier in the year, this would also be a good strategy for the wrapped Bitcoin. But generally we are happy to support this initiative from a product/design/engineering standpoint if approved.
