There's stats about greenhouse gasses that adjust for exports and imports.

This has traditionally made China look slightly better and the countries that buy their exported goods slightly worse.

But if you buy an EV built in China you're investing some carbon and then every mile you drive reducing carbon compared with an ICE equivalent. Solar panels and wind turbines are similar.

I saw someone claim that Chinese green tech exports in 2024 caused a 1% drop in global emissions which is an absolutely wild number and presumably if counted towards China means they are already on the downslope of carbon and not on a plateau as they are if you consider only their territorial emissions.
