BEIJING China will spend 350 billion yuan ($56 billion) by 2015 to curb air pollution in major cities, the environmental watchdog said on Wednesday.
Local governments will fund most of the programs aimed at cutting the level of harmful particles in the air in 117 cities by at least 5 percent between 2011 and 2015, the Ministry of Environmental Protection said in a statement on its website.
Doctors warn that the tiny floating PM 2.5 particles, named for their less than 2.5 micrometer diameter, can settle in the lungs and cause respiratory problems and other illnesses.
China began publishing data on the amount of such pollution earlier this year in an effort to address concerns from residents that pollution readings were grossly understated.
Chinese officials have acknowledged that the thick cocktail of smokestack emissions, vehicle exhaust, dust and aerosols that often fills the air in many cities is a growing concern to increasingly prosperous urban residents.
Many Chinese in Beijing refer to an air pollution index published by the U.S. embassy, a move that has drawn the ire of Chinese officials who have called it unscientific.
Those measurements, based on U.S. standards, appear much grimmer than those of the city government's and often list pollution levels as hazardous at prolonged exposure.
China has cited its ongoing reliance on heavy industry as the reason it failed to meet some of its 2011 air and water pollution reduction targets.
Earlier government projections gave more ambitious pollution reduction targets. State radio reported in February that Beijing would reduce PM 2.5 levels by 15 percent by 2015 compared with 2010 levels, and cut overall air pollution levels by 30 percent over the same period.
