Capitalism is the cause of climate change. Corporations are interested only in max profits. This won’t change under capitalist countries, ever. Study socialism and join a local org or party that you ideologically support.
China is controlled by the communist party and its policies aren’t driven by short-term profits. There are corporations but they can’t go against the interests of the Chinese society, unlike the USA. Look at how China generates more clean energy than the UK total electricity output.
