Long-Term Impacts of Global Solid Biofuel Emissions on Ambient Air Quality and Human Health for 2000-2019.

Globally, solid biofuels (SB) have been widely used for household cooking and energy production for decades due to electricity shortages and socio-economic barriers to adopting renewable energy alternatives. This has detrimental effects on air quality, human health, and climate through trace gas and aerosol emissions. Despite numerous studies, the long-term consequences of SB emissions remain poorly understood.

The short-term comprehensive impact of the phase-out of global coal combustion on air pollution and climate change.

With the continuous intensification of global warming, the reduction and ultimate phase-out of coal combustion is an inevitable trend in the future global energy transformation. This study comprehensively analyzed the impact of phasing out coal combustion on global emissions and concentrations of air pollutants, radiative fluxes, meteorology and climate using Community Earth System Model 2 (CESM2). The results indicate that after the global phase-out of coal combustion, there is a marked decrease in the concentrations of sulfur dioxide (SO), nitrogen oxides (NO) and fine particulate matter (PM), with some regions experiencing a reduction of exceeding 50%.
