You may also have problems if you're connecting through corporate firewall. I won't name a certain Chinese well-known corporation using certain McAfee shitware that managed to block ExpressVPN and VyprVPN within a week for me, making it significantly more difficult to do my job there.

If you are flying in through HK get a china unicom hk cross border SIM. Somewhat expensive data but a life saver in those situations since there is no firewall.

I did for the second half of the stay. Absolute lifesaver.

Aren't they building nuclear plants now?

A few, not enough to make a dent in coal usage. And I'm not sure how many self-heated homes in the villages can be converted from coal to nuclear (electric heating is too inefficient...but maybe they can use a waste core like they did in the Martian?).

Electric-powered heat pumps are much more efficient than any kind of coal burning - they run at 500%+ efficiency (they move heat around instead of generating it).

Seems like a nice solution for the future...efficient heat pumps are kind of new technology.

Also, more insulation would be nice. China housing is very substandard in the villages.

That's just CO2. What about sulphur oxides, particulate matter, and the like? "Pollution" is a general term.

Better late than never: it's hard to get reliable data on such things, CO2 estimates are probably at least somewhat correct.

The larger point being that you have to take into account how many people live in a country, you can't just compare countries without that.
