... did you link the correct article? It seems quite critical of China's emissions?

None of the world's biggest emitters -- China, the United States, the European Union and India -- have reduced their emissions enough to meet the Paris Agreement goals.

Over the past two decades, China’s emissions have surged as the country has developed economically at a breakneck pace. Mainly because of its reliance on coal, one of the highest-emitting fuels, China now accounts for almost a third of all human-caused greenhouse gases — more than the United States, Europe and Japan combined.

Granted, the article says that China's emissions are projected to peak in 2025, but that still means emissions are estimated to increase every year for another 3 years. They have not (yet) actually reduced their annual emissions, let alone achieved anything close to net-zero.

According to projections from Climate Action Tracker and other monitoring organizations, China’s emissions are nearing their peak, years ahead of when China’s government had pledged to reach that goal. Analyses show China’s rate of emissions neither growing nor declining from now until 2025, before gradually dropping off. China’s peak will occur at a far lower per capita emissions level than countries like the United States.

The goal that China has beaten, it would seem, is their own internal peak date goal. It's good that they set and kept a goal, but keeping an internal goal is not the same thing as keeping the Paris Accord goals. The Paris Accord represents the bare minimum for avoiding a climate catastrophe and should continue to be the primary bar which we measure countries against.

Fair enough if we're going just on pledges on total emissions change by 2030 than China and many other countries like India, Sweden, Denmark and Morocco are in line for the pledges taken. This is just a component of the Paris Accords the main pledge was to take action to limit warming well under 2 degrees. No countries action or policies are in line to meet that pledge. That can be seen in the article you linked showing how far off all four emitters are to 1.5.

Climate action tracker and the CCPI they put out are the best sources for accurately tracking countries actions. China and pretty much all other countries fall down on their net zero targets rooted in fiction and missing NDC targets.
