This is a timeline of pollution in Beijing, attempting to describe progression in coping with all kinds of pollution in the city.

Big picture

Time period Development summary
1970s Environmental protection starts in the late decade in China and Beijing.[1]
1980s Beijing starts to build its air quality monitoring system.[1] Air pollution starts becoming a major problem in northern China. The city already experiences photochemical smog.
1990s Air pollution in Beijing becomes very severe.[2] By the late decade, the ambient concentrations of pollutants including sulfur dioxide and total suspended particles in Beijing seriously exceed Chinese national air quality standards.[1] The first local government air pollution control program in China is introduced in the city. Multiple emission standards start being introduced.
2000s Air pollution remains a serious problem in Beijing during the decade, marked by very frequent pollution episodes, especially during the winter.[3] Air quality in Beijing improves significantly during and after the Summer Olympic Games, but most of the effect fades away by the end of October 2009.[4]
2010s Air quality monitoring stations aire introduced. Beijing issues red alerts for severe pollution in 2015, the first since the emergency alert system was established. Toward the second half of the decade, emissions of PM2.5, sulfur dioxide, and nitrogen oxide are found to be reduced by 97%, 98% and 86% respectively compared with 20 years earlier, resulting in significant environmental and health benefits.[1]
