Clean Air China (CAC) Consolidation Phase
Air pollution poses a significant challenge to public health, environmental sustainability and the climate particularly in Asian countries such as China. Knowing the sources of pollution is essential to formulate adequate policies. The Swiss Paul Scherrer Institute (PSI) together with its Chinese partners from the Institute of Earth Environment (IEE) will transfer an innovative air pollution source identification model developed under phase 1 and capacitate the cities to run the model independently.

- A real-time source apportionment model has been developed under the lead of PSI in collaboration with the (IEE).
- Using the model, city reports were produced analyzing the sources of pollution in Beijing, Xi’an, Wuhan, Chongqing, Langfang and Shijiazhuang.
- Based on the results, the city of Xi’an adjusted its policies on the burning of biomass fuel.
- Due to Covid-O restrictions in China, the model during phase 1, could not fully be transferred to the end beneficiaries i.e. selected municipal Environment and Ecology Bureaus (EEBs).

Contexte |
Air pollution is a major threat to public health causing between 1.5 and 2.2 million premature deaths per year in China only. The pollutants also affect the climate. China like other countries and cities around the world is confronted with the challenge of adopting effective science-based policies to improve air quality. Understanding the sources of pollutants is particularly difficult in the case of secondary pollutants. They are concerning as they can be formed from various combination of many different compounds. The PSI plays a leading role worldwide in developing specific scientific models tracing back the sources of secondary pollutants and the conditions of their formation in real time. Developed through a collaboration between Swiss and Chinese institutes, the model from phase 1 of the DEZA-PMF project is now ready for transfer to cities. |
Objectifs | Relevant chinese authorities are equipped and can run a scientific model allowing to trace back the sources of secondary pollutants in real time, allowing them ultimately to take appropiate measures to accelerate their fight against air pollution. |
Groupes cibles |
Direct: The male and female employees of the municipal Environment and Ecology Bureaus (EEBs) of Beijing, Xi’an, Chongqing and Wuhan in charge of air quality control. Indirect: 80 million inhabitants of the 4 cities who will benefit from improved air quality in the long term (beyond project timeline) due to policies adopted based on the scientific data given by the model. |
Effets à moyen terme | The four targeted cities in China have improved their capacities to identify the sources of pollution. |
Résultats |
Principaux résultats attendus: Output 1 Enabling model optimization and validation for training and demonstration. Output 2 Training and documentation to ensure that real-time source apportionment is integrated into the monitoring frameworks of the pilot cities. Output 3 The knowledge and experience developed by the project are effectively disseminated and used. Principaux résultats antérieurs: |
