That's laughable. There is no evidence whatsoever that China will reduce its Co2 emissions anytime soon. The trajectory of Chinese total emissions right now is up and almost exponentially up.China is investing a fortune in green technology. It plans to reduce its emissions by 65% by the end of the decade. More electric vehicles are sold in China than in the rest of the world.
While it is true to say China has been the biggest culprit in recent years due to its fast growth, it is also true to say that China recognises the need to change its energy profile and is investing heavily to do so. Primarily, it sees an economic advantage in doing this before the rest of the world.
I think Just Stop Oil and XR can continue to focus on the UK. It being their country of residence and all that.
A major achievement for China would be if it reduced the rate that it was increasing its total emissions. It can't reduce total emissions until that happens so a 65% fall in total emissions is just again laughable. I'd be surprised if it happened within 50 years.
UK emissions meanwhile ARE falling and they've been falling since the late 90's. Our total emissions are equivalent to what they were in the late 1800's, they're almost negligible. If the UK stopped all activity and became carbon zero then nothing whatsoever would change with respect to the global problem.
However, if China halted its activities and did the same then the problem of climate change would be resolved almost immediately. That's the difference and it's why protesting in the UK is just utterly stupid. China is unfortunately contributing the most to this problem and that contribution is increasing.
