BitGreen BITG proof of work?

I've been looking for green crypto coins and see there is one that doesn't use electricity to make.
It looks like it's made with good deeds. Proof of work.

Has anyone looked into this?
Am I looking at it right?
Can it be tied into the PEP SKIP stuf?

I have not, but have wondered about the use of a token on an existing blockchain to use as an intermediate currency within a permaculture-oriented community (conversions between any of: (1) produce/yield, (2) token, and (3) regional fiat currency can all take place).  Tokens are granted based on yield from the land (so... proof-of-yield?), but since they piggyback on top of an existing ledger system you've got all the proof-of-xyz that comes with that.  Telos might work, still need to evaluate.

Let me know if you're game for bouncing ideas around and I'll be happy to share.  So far no plans to actually implement it, but I don't mind putting the idea out there for anyone else to run with.
