Sumario: | Rural residential energy consumption in China is experiencing a rapid transition towards clean energy, nevertheless, solid fuel combustion remains an important emission source. Here we quantitatively evaluate the contribution of rural residential emissions to PM(2.5) (particulate matter with an aerodynamic diameter less than 2.5 μm) and the impacts on health and climate. The clean energy transitions result in remarkable reductions in the contributions to ambient PM(2.5), avoiding 130,000 (90,000–160,000) premature deaths associated with PM(2.5) exposure. The climate forcing associated with this sector declines from 0.057 ± 0.016 W/m(2) in 1992 to 0.031 ± 0.008 W/m(2) in 2012. Despite this, the large remaining quantities of solid fuels still contributed 14 ± 10 μg/m(3) to population-weighted PM(2.5) in 2012, which comprises 21 ± 14% of the overall population-weighted PM(2.5) from all sources. Rural residential emissions affect not only rural but urban air quality, and the impacts are highly seasonal and location dependent. |
