I wonder how much CO2 impact the CI revolution in open source really has. While I see how this is convenient, I sometimes wonder if we really need to spin up a 30min build for every PR/commit. I have never heard the community reflect on the impact it has with all the convenient cloud computing. Just spin up a ton of hosts to do your thing, yes? If you can pay for it, its OK? I guess owners of fossil-fuel consuming vehicles think the same. So, where are the environmental activists in the open source area pointing fingers at CI usage?
