Ask HN: Low-Carbon VPS Hosting?

Recently, we (a small digital agency working mostly with non-profit orgs) are getting asked more and more often about low/no-carbon hosting. We currently host all our production sites on Digital Ocean and staging sites on Hetzner, I've reached out to DO in the past about green hosting options but it's apparently not something they're particularly interested in. I know of some green hosting options for bare metal, but I'm having a hard time finding anything DOish, VPS that we can spin up and kill at will. Anyone have any recommendations?
