China launches new air quality plan

China announced a new action plan aimed at sustainably improving air quality. The plan includes tightening standards for fine particulate matter "PM 2.5" and imposing more stringent restrictions on other pollutants such as "PM 10," sulfur dioxide, and nitrogen oxides. Measures will be tailored to local conditions, with strict controls remaining in key areas like Beijing-Tianjin-Hebei and the Yangtze River Delta, focusing on upgrading industrial, energy, and transportation structures, as well as updating emission standards and supportive policies. China has made significant progress in reducing air pollution, with the average concentration of "PM 2.5" decreasing by 59% since 2013, reaching the lowest levels of heavily polluted days.
