BEIJING, June 3 (Xinhua) -- Automotive vehicles have emerged as a major source of China's air pollution, according to a report released by the Ministry of Environmental Protection (MEP) on Saturday.

China had 295 million automotive vehicles on its roads as of the end of last year, emitting pollutants weighing about 44.725 million tonnes, down 1.3 percent year on year, the report showed.

Analysis of air pollutants of 15 major Chinese cities showed that local mobile emitters, a category that includes vehicles, contributed to about 13.5 percent to 41 percent of total fine particle concentration, according to Liu Bingjiang, a senior official with MEP.

The MEP will enhance supervision on the production, use and elimination of automotive vehicles to reduce air pollution, Liu added.
