EU lawmakers on Thursday shot down a Green Party proposal to research alternatives to the proof-of-work (PoW) mining that underpins bitcoin (BTC).
The Green Party effort followed an unsuccessful attempt by some members of the European Parliament to impose restrictions on the energy-intensive PoW consensus mechanism that some had characterized as a bitcoin ban.
Ernest Urtasun, a Spanish member of the parliament’s Green caucus, told the Economic and Monetary Affairs Committee he was “disappointed” by the decision of lead lawmaker Stéphanie Yon-Courtin to effectively kill the idea by withdrawing her support.
The green proposal, said Urtasun, “by no means interferes” with separate legislation known as the Markets in Crypto Assets Regulation (MiCA) – a law requiring licenses for crypto providers whose details were tentatively agreed upon in June.

“It’s designed as a follow up to that regulation with the aim of supporting the [European] Commission’s future work on that issue,” Urtasun said, shortly before committee members voted to reject his plans.
“There is evidence that crypto-assets can cause significant harm on the climate and environment,” said the amendment put forth by Urtasun, which called for 800,000 euros (US$803,000) of public money to be committed to developing a scientific way to measure the environmental impact of mining and identifying greener alternatives.
Urtasun was seeking to hook his plans into an opinion produced for the parliament’s budget committee, which takes the lead in negotiating how the EU’s overall budget – roughly 185 billion euros per year – should be spent.
