It's a dickmove however you look at it. What we do in the UK in global terms is a fleck compared to the emerging economies, who have already emitted more in the last couple of decades than we have in total since the industrial revolution. China has pumped our more pollution in 8 years than we have in 220.
We are among several countries who have already halved our emmissions.
What politicians currently are doing is a balanced, sensible move to net zero. You can't just STOP OIL. Our entire way of life depends on oil or oil derivatives.
If the government said tomorrow, you can no longer drive your car, have only one child, eat only vegetables, only use electricity for two hours a day. Ban imports from high emmittors, so no tech, and no electricity to run it anyway. All your jobs would collapse, everyone would be destitute, how would you feel about that.
