Transitioning the Ethereum blockchain from proof-of-work to proof-of-stake has reduced its energy usage by more than 99% — and many climate activists have called for Bitcoin to follow suit.
In a Thursday notice following the Merge, the United States-based Environmental Working Group, or EWG, announced it would be starting a $1-million campaign aimed at urging Bitcoin (BTC) to go green as opposed to using an “outdated protocol” like PoW. The announcement came amid environmental activity group Greenpeace launching a petition directly at Fidelity Investments to facilitate the transition to PoS.
“Other cryptocurrency protocols have operated on efficient consensus mechanisms for years,” said Michael Brune, director of the EWG campaign. “Bitcoin has become the outlier, defiantly refusing to accept its climate responsibility.”
