IEA Lowers Projected Carbon Emissions

A New York Times article about an IEA report on future carbon emissions. They are lowering projections due to slower growth worldwide and Chinese efforts to reduce energy intensity. I've been thinking the same thing myself. I didn't buy into the Garnaut Review's idea that business as usual emissions would rise faster than the IPCC previously expected. Though the problem now is distinguishing between business as usual and "business unusual". Is China going for renewable and nuclear energy to reduce imports of fossil fuels and local air pollution or because it expects to eventually to be subject to binding restrictions on greenhouse gas emissions? Or because it wants to be a leader in selling the technology to the rest of the world? All of the above, I think.
