I would also recommend a potentially different name than sustainability or expand it to something like environmental-sustainability. I know it aligns with the effort, but in OSS, "sustainability" is associated much more with contributor or project health than environmental/economic impact. I could see significant confusion otherwise =/
Given that this proposal has to do with environmental sustainability, I don't see a place for it in Contributor Strategy.
I agree that the name should be workshopped to avoid that confusion in the future.
