Smoggy Beijing

The Chinese government is about to put its money where everyone's mouth (and nose, for that matter) is by enforcing an automobile-pollution refueling tax in the notably polluted city of Beijing, Gasgoo says, citing Xcar.

Beijing will be China's first city to enact such a pollution tax when it does so within the next 12 months. With the tax in effect, gas taxes will total ten yuan ($1.62) per liter. Current taxes run one yuan per liter plus 0.1 percent for construction and educational funding.

In January, it was reported that pollution levels on some days in Beijing were reaching 10 to 15 times what the World Health Organization considers the level where fine airborne particulates can pose health risks. As a result, Beijing will attempt to remove as many as 180,000 older vehicles from the roads while cutting dependency on coal-burning heaters.

Additionally, Reuters reported in March that the Chinese government will put into place the country's first-ever fleetwide fuel-economy standard of about 34 miles per gallon by 2015.
