I have been led to believe two things: One is that as a nation, the UK is responsible for less than 2% of global pollution. (Check out South America, India, Russia etc.) Two: China has had a massive growth in ICE car ownership over the last 10yrs, and it is recent history that the Chinese govt was ripped off over subsidies for EV sales. (I do not factor Chinese production pollution levels, as almost every European country and the US has out-sourced their polluting production to China.)
We cannot tell the rest of the world they should be making an effort if we are not making an effort ourselves.
China came to an industrial revolution only relatively recently, we stupidly, were happy to let them do our manufacturing for us, now we cry our eyes out because they have learned to manufacture far better than we could ever do.
I saw some information the other day they are creating windfarms faster than us or the EU.
We are so far behind, we guarantee stupid electricity prices to owners of windfarms to get them built, then start arguing about how to get the electricity onto the grid. Why, because the grid is now privately owned.
Natural or man made, we know the world is heating up, we know this means wilder more extreme weather, so we want to expand the grid with overhead cables!
All that is needed is humanity to learn to live more efficiently in energy terms, then no matter who was wrong or right about global warming we all gain.
