About Filecoin Green 

Filecoin Green is our effort to make rich environmental accounting a Web3 Superpower. We're doing this by building the tools to measure the environmental impacts of Filecoin and verifiably drive them below zero, building infrastructure along the way that can be leveraged by anyone to make transparent and substantive environmental claims for their own operations.
