What? But China ratified the Kyoto protocol and pledged to reduce their pollution. This can't be true! It's almost as if the country completely disregarded the treaty to grow their economy at any expense.
EDIT: and, of course, it was about CO2, not particulates. A country can make certain trade-offs about different types of pollution (particulates v. CO2 v. NOX).
Per-capita emissions are one way of accounting for the obvious fact that if Denmark (a nation of 5 million people) generated as much CO2 per year as Germany does (a nation of 80 million people), Denmark would in this hypothetical be more blameworthy, and it would be fair to ask Denmark to reduce its emissions more than Germany, as it would already be emitting far out of proportion to its size. Put differently, if every country reduced their per-capita emissions to China's level, we'd actually be in great shape. That suggests that China is not the main problem.
In 2012 they emission of carbon dioxide raised by 3%, but that increase was at least lower than in previous years, where it oscillated around 10% (http://www.bbc.co.uk/news/science-environment-24742770)
29 of 71 nuclear reactors that under currently under construction are being built in China (http://world-nuclear.org/info/Facts-and-Figures/World-Nuclea...), they also have similar numbers for hydropower (see the previous link).
