But the energy from windmills doesn't have a CO2 tax (it did at some point) and it frequently provides most, if not all, of the Danish energy (electricity) consumption. There's ONE coal fired power plant left in the country and it's scheduled to close in 2028. I get that we then have gas and garbage incinerators for heating, but we are getting electrification and lower prices.

I frankly don't care what the US and China is doing, because they're doing the wrong thing. You're arguing that because you neighbour is throwing trash in the street you want to be able to do the same. I'd much rather make environmental demands of the products being sold to be from else where, and have them live by the same rules, allowing everyone to benefit.

Co2 tax is just an indirect subsidy for renewables. When prices are low those are subsidized through cfds. When high- through merit order artificially pumped by co2 tax. This isn't bad per se but it affects negatively final consumer prices and industry which is bad.

Problem is not about the neighbors throwing trash. Unilateral co2 tax means industry relocates to regions where it's not present. In your analogy it would look like you are sending trash to US to deal with it.

DK is lucky to be able to get firming from nordics, but not everyone can do this. And from what I remember Norway already said one of the interconnectors will not have extended license at EOL
