green cryptocurrencies!!!

Let's use this amazing innovation system to support the world we would like to create!
Id like to use this as a platform to discuss cryptocurrencies that have a positive environmental impact!

so far on my radar is

1. Power Ledger- ideally paying in crypto for energy generated via solar panels and sold to the market.

2. Evergreen Coin- seems to be oriented towards co-ops and farmers, with a focus on water, renewables, and cannabis!

now, these are really the only ones I've found and it's still unclear if they are actualy doing any good for the environment, yet, still, This is the paradigm I want to see in the world: a focus on our food and our relationship to the earth!!!!

So my question to you all out there is this: what other cryptos have you been researching that have inspired you with their technology, their message, or their mission?

Also, I'm wondering how we get more people from developing nations involved. they can have so many environmental issues without the resources or the voice to be heard. who knows where your charity money actually goes but what if you could pay the child who put together your iPhone directly with crypto. it might not make sense now but in time, these people's lives would change, hopefully for the betterment of all.
