Or soon will be.

That of course is why they were exempted from Kyoto:

SHANGHAI, China (AP) - China will pass the United States as the world’s biggest source of greenhouse gasses this year, an official with the International Energy Agency was quoted as saying.

China had been forecast to surpass the U.S. in 2010, but its sizzling economic growth has pushed the date forward, the IEA’s chief economist, Fatih Birol, was quoted as saying in an interview appearing in Tuesday’s Wall Street Journal newspaper.

“In the past couple of months, economic growth and related coal consumption has grown at such an unexpected rate,” Birol was quoted as saying. China’s rising emissions will effectively cancel out attempts by other countries to reduce their own, he said.

China is a signatory to the Kyoto Protocol on reducing greenhouse gasses, but is exempt from its restrictions because it is a developing country.

Good thing the whole global warming thing is a big lie because there’s nothing we could do to stop it.

Small wonder that China signed the treaty.  That gives them a huge advantage over the suckers that are abiding by the treaty.
