Yesterday night when I was lying half awake in my bed I was thinking/dreaming of a carbon neutral blockchain.
Question: has anyone seen one or knows of someone who is trying to build one?

#2Nah.
Longer version: Proof or work wastes energy by design, and while proof of stake is less wasteful, it is still not remotely as efficient or performant as modern banking systems. Proof of (hard drive) Capacity is wasteful of device production and running energy, and proof of elapsed time seems to be a lottery system, which looks likely to be difficult to secure in practice.

Exactly what I came here to say, thank you.

#4Chia is about as close as you can get. Created by the guy who wrote Bittorrent.

#5Hyperledger ecosystem might be of interest, Fabric uses Proof of Authority by default

#7Blockchain itself cannot be carbon negative or neutral. Miners choose what energy source they use for mining, which can be anything from fossil fuels to geothermal energy from volcanoes.

#8Blockchains that don't use proof of work are as wasteful as any other electronic platform
Also proof of work can be translated into anything, like serving websites, images, processing video, and in that case is equivalent to any cloud or hosting provider
