Long-term Trends of Impacts of Global Solid Biofuel Emissions on Air Quality and Human Health during 2000-2019

Previous studies have shown that global solid biofuel emissions play an important role in air quality and human health. However, the global long-term trends of impacts of solid biofuel emissions on air quality and human health are still not well understood. In this study, we use the Community Atmosphere Model version 6, coupled with chemistry (CAM6-Chem) within the Community Earth System Model version 2 to investigate the long-term trends of impacts of solid biofuel emission on atmospheric chemistry, air quality and human health for the period of 2000-2019. We will quantify the trends of regional and global annual total emissions of aerosol and trace gas species from the solid biofuel sector during 2000-2019. The subsequent air quality and human health impacts will be quantified, with a focus on PM2.5 (particulate matter with aerodynamic diameters ≤ 2.5 µm) and ozone. Our study has significant implications for regional and country-level environmental justice associated with human health impacts for the residential emission sector.
