Xinhua: China will implement carbon tax

China, the nation that emits more carbon dioxide from industrial and other sources than any other in the world, will soon implement policies that would create a financial disincentive to add greenhouse gas pollution to the air.

Xinhua reported Tuesday that the world's most populous country will impose an "environmental protection" tax policy that will include assessments on carbon dioxide emissions.

The story did not indicate when the emissions tax would be put into effect.
