Yep, China are following the “developed” world’s example.
To be fair, China is doing it slightly better. For instance, they have by far the fastest deployment of wind and solar electricity generation. The expansion of coal is more for smelting than for electricity, and that goes against central government policy – big place, China, and local authority often prevails over the national government.
And it must be remembered that much of China’s emissions are from industry for export – China is the manufacturing hub of the world, so although the emissions occur in China, the actual consumption and the money to pay for it are Western.
But no, it’s not remotely sustainable. China is an offender along with all the other major governments – just somewhat less so, particularly on a per-capita reckoning.
