I believe this news shows how political and economical all this "carbon" discussion is, and not really ecological.
Curious is that bitcoin is not being banned from Switzerland. Probably eletric cars consume much more energy there.
Europe is going through a whole lot of energy crisis and they are taking drastic actions to ensure that available energy is used efficiently. Switzerland main source of power is hydropower but the country has to rely on imported gas for heating during summer. And report shows that 43% of this imported gas comes from Russia. As European nations try to boycott Russian supplies there is need to make sacrifices to achieve this aim. The swiss government is even considering regulating sports, the theatre and even crypto mining. Currently European nations' main priority is survival and not the environment. When this crisis is over, the voices of the protectors of the environment would become louder, but for now, they need to live to fight for mother earth.
