Over the past decade, China has made remarkable progress in controlling air pollution. Today, China has embarked on a new journey to fight for its blue sky, and a new road map of blue sky is being rolled out. Looking ahead, we hope to see more joint efforts by the government, enterprises and the public to draw on the successful experience of air pollution control over the past decade, including monitoring and infomation disclosure. We also hope to see multiple stakeholders leverage the huge impetus from the dual carbon targets on structural adjustment and low-carbon transition, vigorously promote the synergies of carbon reduction and pollution reduction so as to ensure that air quality is further improved while high-quality carbon peaks are achieved before 2030. These efforts will promote the building of a beautiful China and alllow the country to share its wisdom and strength to the building of a beautiful world.

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.

IPE looked at all the progress that China has made since 2014 in terms of early warning smog alerts and the identification of pollution sources and key emissions reductions. Policy recommendations have also been put forward around the scope of monitoring, improved air quality forecasting capabilities, expanded real-time disclosure of online monitoring, and the Shandong model of establishing an environmental protection micro-reporting system at four administrative levels.
