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 beneath the 2015 Paris Local weather 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 companies.

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 operating of cryptocurrency-exchange companies – has seen producers turning their consideration elsewhere.
This consists of 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 obtainable to us will likely 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 includes contributing laptop 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 ‘gasoline’, the price of which is ready by the miners based on the provision and demand on the community. The extra highly effective the pc, the extra possible a miner will obtain a coin.
However this course of additionally calls for an enormous quantity of power. In line with 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 attainable 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 on daily basis. This isn’t an inexpensive use of our renewable power”.

Various 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 impression. Nonetheless, they notice that neither of those choices are wish to sort out the quick drawback, 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 forestall firms 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 nations with a friendlier stance on cryptocurrencies however little or no entry to renewable power sources, Thedéen and Risinge say “it will be important that Sweden and the EU cleared the path and set an instance with a view to maximize our possibilities of assembly the Paris Settlement,” they usually name on different international authorities to comply with go well with.
They add: “A ban on the proof of labor mining methodology throughout the EU may very well be an essential first step in a worldwide transfer in the direction of a larger use of extra energy-efficient crypto mining strategies.
“It could additionally imply that our renewable power is used as effectively as attainable with a view to assist the transition in the direction of local weather neutrality.”
