According to http://www.wri.org/sites/default/files/pdf/global_coal_risk_..., they plan to build 'only' about 40% of new coal plant capacity, with India taking another 35%.

So, not that that matters for the absolute pollution, but if that >50% is correct, their mix will improve.

Also, they try to build those plants far away from cities. That, hopefully, will spread pollution.

That PDF also states that those plans may not be implemented, as a) coal companies lose money in China because the government fixed electricity prices and b) the public doesn't want their pollution.

On the negative side, their absolute pollution will likely go up, and the gap with the western world will go up even more (elsewhere, new coal plants will often replace older, more polluting ones)
