Members of the European Parliament have voted against an amendment to the Regulation on Markets in Crypto-assets (MiCA) which would ban mining proof-of-work cryptocurrencies in the European Union[1].
Authors of the amendment argued that mining proof-of-work cryptocurrencies consumed too much energy. Approving the amendment would in fact mean the ban on mining a range of cryptocurrencies, such as bitcoin, ether and litecoin, until they switch to less energy-intensive consensus mechanisms, e.g. proof-of-stake.
As a result of rejecting the amendment, the Committee on Economic and Monetary Affairs of the European Parliament agreed to ask the European Commission to include cryptocurrency mining in the EU taxonomy for sustainable activities by 2025 to reduce carbon footprint.
