Yes they are - they've been routinely beating their targets for achieving carbon neutrality
Their targets were less aggressive than ours, but there are very different challenges in achieving it at the same time as developing their economy and taking millions of people every year out of subsistence farming.
They planned to peak emissions in 2030, but will now achieve it in 2025.
Targets for amount of renewable power coming on board there are also 5 years ahead of schedule, and dwarf any other country in the world.
Chinese developments in perovskite/silicon solar cells can produce solar cells that are 50% cheaper and produce 50% more energy, and will transform the market in the next few years.
They are the biggest market for electric vehicles, selling more than the rest of the world put together - 22% of new vehicles there were electric.
They are reforesting huge areas, pledging to plant 70 billion trees in the next 5 years.
Their planned date for carbon neutrality is 2060 vs our 2050, but they are ahead of schedule.
They don't need to do any of this to win votes, or due to international pressure, they're doing it because they can also see that it is the right thing to do.
