Why reduce UK emissions when countries like China produce loads more CO2 than we do?

China is currently the largest greenhouse gas emitter in the world, but it is decarbonising much faster than countries like the US. China generates almost half of the world’s installed offshore wind, with 26 gigawatts of a total of 54 gigawatts worldwide in 2021. Last year China had an estimated 2.7 million people employed in the solar energy sector, making up more than half of the world’s 4.3 million solar jobs. Source: Harvard.
