I don’t think it follows from that that “the actual climate change problem isn’t getting people in the UK to use less“. China has 31 provinces, so if you look at China’s emissions by province, there will be quite a few that are at the level of CO2 emissions of the UK or below it. By your logic, that would mean the actual climate change problem isn’t getting people in those provinces to use less.
If so, who has to do something?

If we can do that, we can cut the UK’s emissions, too.
I also think it’s not about ‘raising’ the world to what the west currently does, but about changing western standards of living. I think there’s substantial room for decreasing CO2 emissions without decreasing well-being (thought experiment: would people be less happy if the airplane hadn’t been invented? If we had run out of oil in 1980?)
You are ignoring the important part of why he divides people into "China" and the "UK". It's not an arbitrary distinction it's the unit with which laws get enacted and have affect. And China can set laws that affect all provinces. If the UK cuts climate change by enacting local laws it'll make the UK worse off, and the rest of world marginally better off. So the smart thing to do from the UK side is not to focus on local laws that reduce carbon footprint but on items that have global reach, such as treaties and technology.
Re: well being, I think it’s a losing argument. Efficiency and better technologies are more likely to happen than mass enlightenment. I think it depends on what you mean by well being. I suspect people are generally happier for the progress that’s been made in reducing extreme poverty globally, which couldn’t have happened without a cheap and efficient portable energy source like oil. If you’re only measuring western upper middle class educated folks, I’ll wager their well being is worse. But I think you can’t separate the two - the lifting of billions out of extreme poverty and the enshittification of middle class life in the west. But whether you can or not, oil bootstrapped us to this point. But I think we’re demonstrably past bootstrapping and we absolutely must do something different.
