Emissions cap shows Beijing's 'sincerity'

Experts say plans to reduce carbon intensity key to long-term growth

Some cities in East China have started planning how to cap their greenhouse gas emissions, and their experiences will act as an example for other cities, a climate change expert has said.

China has set a national target to cut carbon intensity emissions per unit of GDP by 40 to 45 percent between 2005 and 2020. Determining how to achieve this target is to be decided by local governments.
