Bitcoin mining may soon be reducing more emissions than its energy sources produce according to Daniel Batten, cofounder of CH4Capital. Batten is a partner in a fund raising $400 million to fund projects mitigating vented methane from landfills by using the gas to mine bitcoin.

“Once fully deployed, we will have enough capital to take the entire Bitcoin Network carbon negative,” Batten told me in our interview, a claim that flies in the face of recent high profile bitcoin critics.
