China is the world's largest carbon emitter and coal de-capacity is a policy with immediate and substantial CO2 reduction effects. However, the carbon emission reduction and health co-benefits arising from the coal de-capacity are often ignored. Here, we assessed the carbon emission reductions and quantified the health co-benefits from coal de-capacity based on an analysis of the spatial and temporal distribution characteristics of the mine closures and phase out during 2016-2022. Our findings show that China had closed/phased out a total of 4027 mines with a total de-capacity of 8.75 x 108 t, spatially concentrated in Southwest and North China from 2016 to 2022. The coal life cycle emitted 1859 million t of carbon during the coal de-capacity. Importantly, 11,775 premature deaths were avoided during 2016-2022 due to reduced PM2.5 exposure as a result of coal mining. This study highlights the significant effects of coal de-capacity on carbon reduction and health co-benefits in China and provides scientific evidence and data to support the achievement of the sustainable development goals and the 'dual carbon goals'. |
