There is widespread fear that Chinese coal consumption — which nearly rivals the entire rest of the world combined — will undo our efforts to combat climate change. Last week, I suggested that the only way to prevent that happening was to lead by example , cutting our own emissions in a way that was unambiguously aimed at fighting climate change:
The Chinese state isn't necessarily adverse to following the lead of the West in cutting carbon emissions, so long as its clear that we actually are doing it to fight climate change. That's an argument for installing carbon capture and sequestration technology, for instance, because that's something which has no other purpose. Of course, such technology needs to improve its efficiency — both in how much carbon it can scrub, how long it can store it, and how much it costs to do — but to do so would send an unequivocal message that the fight was one we wanted part of.
But it may not even come to that. The other trend I discussed — that of developed nations cutting coal usage for reasons unrelated to climate change — looks like it's about to hit China to. Grist's David Robert's writes :
Most projections  (PDF) have coal use in China continuing to increase for decades to come. But there are reasons  to think those projections overstate demand — that China’s appetite for coal may peak sooner than expected. For one thing, the Chinese government is signalling that the country’s coal consumption will peak by 2015 , at 4 billion tonnes.
Obviously, a "non-binding" plan to make a plan to cap coal use is not the same as actually doing it. But not only does the Chinese government have good reason to do so — coal is a horrible pollutant, and China already has noted problems with air quality  — the counterpoints are rapidly fading away. Much of the fear of ever-expanding coal use was based on an assumption of ever-expanding GDP. That assumption is being tested , and has given rise to fears of a "hard landing". But whether or not the Chinese economy crashes to the floor or gently glides to a less frenetic plateau, some of that slowdown will result in a natural reduction of the increase in coal use.
The bigger problem, Roberts points out, is the fact that the central government doesn't have the best control over the actions of the provinces. That's an issue which impacts on almost every issue in China, and fighting climate change is no exception. But if Chinese officials really are saying they will do "whatever it takes ", then maybe it can be overcome.
