ted at the province level in China, the researchers used waste gas emissions, available from China's state environmental protection administration reports, as a proxy for CO2 emissions in this paper.
Moreover, the researchers said, the majority of other studies forecasting China's CO2 emissions relied upon information from nearly a decade ago. During the 1990s, per capita income was growing faster than the use of energy in China, which typically relates to slower growth in carbon emissions.
"A notable shift occurred in China around the year 2000, around the time when hope for an agreement with the U.S. on the Kyoto Protocol began to diminish along with external pressure for China to reduce its emissions," said Carson. "Energy use started to grow faster than income, and much of the energy that was used wasn't efficient."
The authors also pointed out that after 2000, China's central government began shifting the responsibility for building new power plants to provincial officials who had less incentive and fewer resources to build cleaner, more efficient plants, which save money in the long run but are more expensive to construct.
"Government officials turned away from energy efficiency as an objective to expanding power generation as quickly as they can, and as cheaply as they can," said Carson. "Wealthier coastal provinces tended to build clean-burning power plants based upon the very best technology available, but many of the poorer interior provinces replicated inefficient 1950s Soviet technology."
"The problem is that power plants, once built, are meant to last for 40 to 75 years," said Carson. "These provincial officials have locked themselves into a long-run emissions trajectory that is much higher than people had anticipated. Our forecast incorporates the fact that much of China is now stuck with power plants that are dirty and inefficient."
