The Bitcoin community supporting environmental causes is nothing new. Just a few months ago Genercoin was released by Arterran Renewable Fuels. The basis of Genercoin was a new biofuel developed in the Arterran labs. Each Genercoin represented a certain amount of the fuel, based on British Thermal Units (BTUs). One Genercoin might be worth 10,000 BTUs for instance. But a new development is completely different and might have a significant effect on carbon emissions.
For the tree hugger in you.
