Carbon dioxide (CO2) emissions by Chinese power plants are expected to surpass U.S. utilities' emissions of the main greenhouse gas by 2017, according to the Center for Global Development.
U.S. utilities spew out some 2.8 billion tons of CO2 annually while Chinese power plants are emitting 2.7 billion tons a year, according to the CGD study. The survey ranked individual power plants in different countries according to their CO2 emissions. "Globally, power generation emits nearly 10 billion tons of CO2 per year. The U.S. with over 8,000 power plants out of more than 50,000 worldwide, accounts for about 25% of that total," the survey found.
The report claimed that the biggest U.S. CO2 emitter is Southern Co. whose power plants belch out 172 million tons of the principal greenhouse gas annually, followed by American Electric Power Company Inc., Duke Energy Corp., and AES Corp. The state with the biggest CO2 emissions from electricity generation is Texas which accounts for 290 million tons of emissions, followed by Florida (157 million tons) and Indiana (137 million tons).
China's largest emitter is Huaneng Power International which accounts for 292 million tons of CO2 emissions.
Researchers said U.S. emissions were high partly due to high living standards, but also differences in energy policy. "Europeans, with comparable living standards, emit less than half the power sector CO2 of the average American," said CGD president Nancy Birdsall.
The researchers, who want to speed the shift to less carbon-intensive power generation and minimize global warming, created a data base from their findings. The online data base called CARMA (Carbon Monitoring for Action) can be accessed at www.carma.org.
