1. The EU to consider an EU-level ban on the energy-intensive mining method proof of work. There are other methods for mining crypto-assets, that could also be used for Bitcoin and Ethereum, that are estimated to reduce energy consumption by 99.95% with maintained functionality.
2. Sweden to meanwhile introduce measures that halt the continued establishment of crypto-mining production using energy-intensive methods.
3. That companies who trade and invest in crypto-assets, that were mined using the proof of work method, cannot be allowed to describe or market themselves or their activities as sustainable.''
''A ban on the proof of work mining method within the EU could be an important first step in a global move towards a greater use of more energy-efficient crypto mining methods.''

Edit:
Changed the topic
''Why are they against PoW?''
to
''They will try to stop Bitcoin''
- that is my opinion -
... or the topic could be:
The topic of this thread should be : "they wish they could stop Bitcoin"
Much better, I tend to agree with you.
