Environmental Groups to Spend Another $1M on Ads for Bitcoin Code Change After the Merge

Environmental groups pledged to spend another $1 million on online ads to pressure the bitcoin community to change the network's code in order to reduce energy consumption.

Earlier on Thursday, the Ethereum blockchain – which underpins the world's second largest cryptocurrency – changed its consensus mechanism from proof-of-work (PoW) to proof-of-stake (PoS), doing away with the need for energy-intensive computing power. Bitcoin, a PoW network, has been facing mounting criticism over its energy use, which is on par with some small countries. These criticisms were echoed in part in a report on bitcoin mining published by the White House last week.

"Ethereum’s energy-efficient ‘merge’ leaves bitcoin as lone cryptocurrency climate polluter," wrote Environmental Working Group (EWG) in a Thursday statement, which along with Greenpeace USA, Ripple co-founder Chris Larsen and other small environmental organizations launched a campaign to change the bitcoin code earlier this year.

On top of the new ad funds, Greenpeace USA started an online petition calling on multi-trillion-dollar asset manager Fidelity Investments to help take the lead in pushing Bitcoin to switch to PoS.
