Air quality and health benefits of achieving carbon-neutrality in building sector over Beijing, China.

To meet the goal of the Paris Agreement, China pledges to realize the "Dual Carbon" targets by 2060. As the capital of China, Beijing plays a leading role in becoming zero-emission or carbon neutral in the future. We project the pollutants emissions of building sector based on current strict clean air policies (PO scenario) and China's carbon neutrality target by 2060 (CN scenario) from 2019 to 2050. Results show that PM _2.5 concentration will increase by 2.62 μg/m ³ under PO scenario; under the CN scenario, ozone concentration will increase by 2.53 μg/m ³ but PM _2.5 concentration will reduce by 9.04 μg/m ³ . It is projected that China carbon neutrality goals could avoid 11.12% of PM _2.5 -related health burden; With strict clean air policies, health burdens of ozone (3.9%) and PM _2.5 (4.1%) could be avoided, respectively. This study highlights the importance of achieving co-benefits of air quality and public health.
