Considering the rebound in pollution over the autumn and winter months, how to effectively "differentiate" management strategies and prevent polluters from reverting back to old practices is a major challenge facing key regions and industries, one that will influence the success or failure of the battle for blue skies.

This report mainly focuses on the Air Quality Transparency Index (AQTI) assessment of 120 cities nationwide. The results indicate that the rate at which cities lack PM10 data and data on other air quality indicators is relatively high, and that data from municipal- and county-level monitoring stations is not disclosed in some key areas for pollution control. The "blank space" where monitoring stations are not publishing their data is not conducive to effectively reducing emissions.
