2060?

After dominating the world in carbon emissions? Too little, too late ...

Climate change: China aims for 'carbon neutrality by 2060': 

China is the world's biggest source of carbon dioxide, responsible for around 28% of global emissions.

With global climate negotiations stalled and this year's conference of the parties (COP26) postponed until 2021, there had been little expectation of progress on the issue at the UN General Assembly.

"We aim to have CO2 emissions peak before 2030 [meaning lots more concrete, lots more coal burnt] and achieve carbon neutrality before 2060." [By which time the planet will be cooked and Xi will be 100+ (read, almost certainly dead)]
