One of the biggest obstacles imo to designing and implementing a successful money exchange paradigm is: creating value. Especially with a topic like climate change where adopters aren't likely to see tangible benefits due to the issue of greenhouse gases in the atmosphere being completely invisible to human eyes. We don't see the issue, we only feel the side effects.
There are plenty of projects focusing upon planting trees and minimizing deforestation.
Perhaps it might bode well to focus more on the human element. Its less saturated and the potential for gains more tangible. In practice the way this might work is.
Early adopters and end users of the coin would be entered in a lottery. Periodically, a number of them would become eligible to win solar panels, batteries, electric vehicles, organic plant growing equipment. Items which could enhance their capacity to reduce carbon footprint, reduce greenhouse gas emissions and help combat climate change. With information and experiences being shared, documented and updated. All to empower others to do the same.
That could be a more effective way of producing tangible value, that people would see firsthand moreso than they would with seed planting runs and such. Of which I've never seen much documentation on at all.
