Bitcoin is Fueling the Climate Crisis: Greenpeace USA 

Greenpeace USA – an environmental advocacy group – is calling out Bitcoin for having what it calls an “outdated and efficient” code system. 

In a tweet on Thursday, the organization doubled down on claims that Bitcoin’s proof of work mechanism is contributing to the climate crisis. Instead, it suggested that the code be swapped out for a less energy-intensive mechanism like proof of stake.

The advocacy group’s statements were in response to Ether proof of work chains, such as Ethereum Classic.
