The European Commission issued an 800,000 euro ($842,000) contract on Tuesday as it seeks to mitigate what it calls “significant harm” of crypto on the environment.
The study, for which bids close on Nov. 10, will develop standards that feed into potential future EU policies to curb the impact of crypto on climate change, and to new energy efficiency labels for blockchains.
“There is evidence that crypto-assets can cause significant harm on the climate and environment,” potentially undermining the bloc’s goal to cut greenhouse gas emissions, the European Commission said in tender documents, which suggest that new sustainability standards may be taken up in future laws.
EU lawmakers worry about the energy-intensive proof-of-work consensus mechanism that underpins blockchains such as Bitcoin.
During negotiations last year on the bloc’s Markets in Crypto Assets regulation, they came close to approving green controls that some characterized as a bitcoin ban. Though the final text doesn’t go that far, MiCA does require issuers to declare environmental impacts, using a method that still has to be nailed down.
The EU study, to be produced over the course of a year, will look at green issues like crypto’s use of water, waste products and natural resources as well as energy, the commission said.
