摘要

The use of coal briquettes and improved stoves by Chinese households has been encouraged by the government as a means of reducing air pollution and health impacts. In this study we have shown that these two improvements also relate to climate change. Our experimental measurements indicate that if all coal were burned as briquettes in improved stoves, particulate matter (PM), organic carbon (0C), and black carbon (BC) could be annually reduced by 63 ± 12%, 61 ± 10%, and 98 ± 1.7%, respectively. Also, the ratio of BC to 0C (BC/OC) could be reduced by about 97%, from 0.49 to 0.016, which would make the primary emissions of household coal combustion more optically scattering. Therefore, it is suggested that the government consider the possibility of: (ⅰ) phasing out direct burning of bituminous raw-coal-chunks in households; (ⅱ) phasing out simple stoves in households; and, (ⅲ) financially supporting the research, production, and popularization of improved stoves and efficient coal briquettes. These actions may have considerable environmental benefits by reducing emissions and mitigating some of the impacts of household coal burning on the climate. International cooperation is required both technologically and financially to accelerate the emission reduction in the world.
