These real-time progress trackers use data from China’s official air quality monitoring stations to show which priority regions are on track to meet their air quality targets for the autumn-winter action plan period from October 2020 to March 2021. The targets are set separately for the fourth and the first quarter. Read more about the targets and policies in our briefing.
Note: The average PM2.5 concentrations are calculated from hourly real-time air quality data published by the Ministry of Ecology and Environment, aiming to follow the ministry’s standards for calculating averages for regions and over periods of time. The data can differ from official numbers published by the ministry, but it is reflective of overall trends.
