Keep in mind that the UK has reduced greenhouse gas emissions by 45% between 1990 - 2020, presumably more by now. And one of the UK's leading emitters - the Port Talbot steelworks - has recently announced closure. Only six countries globally are ahead of the UK on this - Sweden, Norway, Denmark, Switzerland, Austria and Finland - all of which have much smaller populations than the UK. So there's no need to beat-up on the UK. This country is more than doing it's share in the continuing drive to reduce pollution.
