20 14 is the second year of implementing the new air quality standards in China, and it is also the second year of monitoring PM2.5 in cities. On February 2nd, the Ministry of Environmental Protection released the air quality status of 74 cities including Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, municipalities directly under the central government, provincial capitals and cities with separate plans in 20 14. The monitoring results show that, compared with 20 13, in 20 14, the number of cities meeting the standards in 74 cities increased from 3 to 8. Beijing-Tianjin-Hebei is still the most polluted area, and the average annual concentration of PM2.5 is 93 μ g/m3, exceeding the standard by more than 1.6 times. In the ranking of cities with relatively poor air quality in China, eight cities were selected as the ten cities with the worst air quality in China.
Among the air, water and soil pollution in China, the cost of air pollution is the highest. From 2000 to 20 10, the cost of air pollution accounted for 6.5% of GDP, water pollution accounted for 2. 1%, and soil pollution degradation accounted for 1. 1%.
In recent years, China government has implemented some air pollution control policies similar to those of other industrialized economies, including providing subsidies for alternative energy sources and compulsory use of certain renewable energy sources; Compulsory scrapping of automobiles, boilers and industrial facilities with high pollution emissions; Install pollution control devices on key pollution sources and vehicles.
The report affirmed China's efforts and achievements in preventing and controlling air pollution, but said that if we want to further improve air quality to a level that does not endanger people's health, these measures are still insufficient and more active policies need to be implemented.
