Swedish authorities have referred to as for an EU-wide ban on energy-intensive cryptocurrency mining, which they are saying threatens targets to restrict international warming to 1.5°C underneath the 2015 Paris Settlement.

In an open letter to the European Union, Erik Thedéen, director of the Swedish Monetary Supervisory Authority, and Björn Risinger, director of the Swedish Environmental Safety Company, warned that the mining of cryptocurrencies like Bitcoin and Ethereum had sparked a rise in power consumption within the nation amounting to “a number of hundred %”.

This cryptocurrency mining is more and more drawing on Sweden’s renewable power sources, which Thedéen and Risinge say is “urgently required for the event of fossil-free metal, large-scale battery manufacturing and the electrification of our transport sector,” in addition to different important providers.

China’s current cryptocurrency crackdown – which incorporates an outright ban on any exercise referring to the issuing or buying and selling of digital tokens or the working of cryptocurrency-exchange companies – has seen producers turning their consideration elsewhere.

This contains the Nordic area, the place costs and taxes are extra beneficial and there’s a plentiful provide of renewable power to faucet into. 

“If we had been to permit in depth mining of crypto-assets in Sweden, there’s a threat that the renewable power out there to us can be inadequate to cowl the required local weather transition that we have to make,” Thedéen and Risinge warn.

The letter particularly requires a Europe-wide ban on the cryptocurrency mining mechanism often known as “proof of labor”, which entails contributing pc processing energy to unravel mathematical puzzles on the community and validate transactions on the blockchain.

On the Ethereum community, the computational efforts required to carry out transactions are often known as ‘fuel’, the price of which is about by the miners in response to the provision and demand on the community. The extra highly effective the pc, the extra doubtless a miner will obtain a coin.

However this course of additionally calls for an enormous quantity of power. In response to Thedéen and Risinge, electrical energy consumption for Bitcoin mining in Sweden now quantities to 1 Terawatt-hour (TWh) yearly – equal to the electrical energy required to energy 200,000 households.

“It’s at present potential to drive a mid-size electrical automotive 1.8 million kilometres utilizing the identical power it takes to mine one single Bitcoin,” they are saying. “That is the equal of forty-four laps across the globe. 9-hundred Bitcoins are mined daily. This isn’t an affordable use of our renewable power”.

Numerous coverage choices are proposed by Thedéen and Risinge to curb energy-intensive crypto mining, together with taxes on cryptocurrency manufacturing and higher communication about its environmental affect. Nonetheless, they observe that neither of those choices are prefer to sort out the rapid downside, significantly “given the speedy progress and demand for crypto-assets.”   

The letter, due to this fact, calls on the EU to introduce measures to halt crypto-mining manufacturing that use energy-intensive strategies, and for laws to stop corporations that commerce and put money into crypto-assets to explain themselves or their enterprise as environmentally sustainable.

Whereas this might result in crypto-producers relocating to international locations with a friendlier stance on cryptocurrencies however little or no entry to renewable power sources, Thedéen and Risinge say “it will be significant that Sweden and the EU paved the way and set an instance with the intention to maximize our possibilities of assembly the Paris Settlement,” and so they name on different international authorities to observe go well with.

They add: “A ban on the proof of labor mining methodology inside the EU may very well be an essential first step in a worldwide transfer in direction of a higher use of extra energy-efficient crypto mining strategies.

“It might additionally imply that our renewable power is used as effectively as potential with the intention to help the transition in direction of local weather neutrality.”
