There is a 55 page pdf proposed low carbon development plan for China by a research group of Chinese economists 50 Forum There are several versions of the plan. I picked up a 128 page copy in Hong Kong and amazon has a longer hard cover version on sale. The longer versions go into more details. The plan was made and presented before the failed Copenhagen climate talks. China is still pursuing increasing energy efficiency needed to generate GDP and making coal plants more efficient and building up nuclear and renewable energy. However, not to the extent proposed in this plan.
They talk about getting to 90% lower carbon than was used in 2005 by 2050.
