Coal-fired power plants (which I believe that China will cut-back on in order to reduce air pollution) are not the only source of Chinese GHG emissions.
The first linked article and associated extracts indicate that that China's plan to build 50 new coal to gas projects will increase CO₂ emissions (compared to coal fired power plants), will increase radiative forcing by a reduction of reflected solar radiation associated with aerosols (produced by current coal-fired power plants), while still producing large amount of NOX that will still damage the health of local Chinese (it seems difficult to imagine a worse policy from a climate change, and a public health, point of view):http://www.greenpeace.org.uk/newsdesk/energy/news/china%E2%80%99s-planned-coal-gas-emit-over-1-billion-tons-co2
Extract: "There could be 50 coal-to-gas projects operational within the next decade, producing 225 billion cubic metres of synthetic natural gas [SNG] per year, if all of the planned ones go ahead, according to comprehensive new research by Greenpeace China.
These 50 would emit around 1.087 billion tons of CO2 per year if they are developed, according to the new analysis. To put this in perspective, it is around one eighth of China’s CO2 emissions in 2011 (8.71 billion tons), and much more than the CO2 cuts from coal control measures by 2020 (655 million tons).
But researchers at Tsinghua University have warned (Report on China’s Low-carbon Development, 2014 [in Chinese]) that the coal-to-gas technology may not effectively lower the emission of air pollutants such as NOx - the main contributor to China’s smog problem."
The second linked article indicates that the increasing use of refrigeration (particularly in China) is a major source of concern with regards to anthropogenic GHG emissions (and could account for up to 50% of GHG emissions by 2050 if not adequately regulated [I am sure that China says that they will regulate these super greenhouse gas refrigerants; however, we will need to see how effective any regulations are that they decide to implement):http://www.nytimes.com/2014/07/27/magazine/what-do-chinese-dumplings-have-to-do-with-global-warming.html?_r=0
Extracts: "Calculating the climate-change impact of an expanded Chinese cold chain is extremely complicated. Artificial refrigeration contributes to global greenhouse-gas emissions in two main ways. First, generating the power (whether it be electricity for warehouses or diesel fuel for trucks) that fuels the heat-exchange process, which is at the heart of any cooling system, accounts for about 80 percent of refrigeration’s global-warming impact (measured in tons of CO2) and currently consumes nearly a sixth of global electricity usage.
But the other problem is the refrigerants themselves: the chemicals that are evaporated and condensed by the compressors in order to remove heat and thus produce cold. Some of that refrigerant leaks into the atmosphere as a gas — either a little (roughly 2 percent a year from the most up-to-date domestic refrigerators) or a lot (on average, 15 percent from commercial refrigerated warehouses). In addition, different refrigeration systems use different refrigerants, some of which, like ammonia, have a negligible global-warming impact. But others, like the hydrofluorocarbons that are popular in China, are known as “supergreenhouse gases,” because they are thousands of times more warming than CO2. If current trends in refrigerant usage were to continue, experts project that hydrofluorocarbons would be responsible for nearly half of all global greenhouse-gas emissions by 2050."
