Abstract
Abstract. Multi-year inventories of anthropogenic black carbon emissions, including both fuel consumption and biomass open burning, at a high spatial resolution of 0.25°×0.25° have been constructed in China using GIS methodology for the period 1980–2009, based on official statistical data and time-varying emission factors. Results show that black carbon emissions increased from 0.87 Tg in 1980 to 1.88 Tg in 2009 with a peak in about 1995, and had been continually increasing in the first decade of the 21 century. Residential contribution to the total BC emissions declined from 82.03% in 1980 to 42.33% in 2009 at a continuous diminishing trend, but had always been the dominant contributor in China. While contributions from industry and transportation sectors had increased notably. BC emissions were mainly concentrated in the central eastern districts, the three northeastern provinces and the Sichuan Basin, covering 22.30% of China's territory, but were responsible for 43.02%, 50.47%, 50.69% and 54.30% of the national black carbon emissions in 1985, 1995, 2005 and 2009, respectively. Besides, China made up 70%–85% of BC emissions in East Asia, half of the emissions in Asia, and accounted for averagely 18.97% of the global BC emissions during the estimation period.
Highlights
Black carbon (BC) emissions have caught extensive concern among the scientific community as a major contributor to global warming and a well established health hazard (Zhang et al, 2010)
Historical black carbon emissions including five sources were estimated for the period 1980 to 2009, as presented in www.atmos-chem-phys.net/12/4825/2012/
Chinese multi-year black carbon emission inventories including fossil fuel consumption, biofuel consumption and biomass open burning were constructed for the period 1980–2009
Summary
Black carbon (BC) emissions have caught extensive concern among the scientific community as a major contributor to global warming and a well established health hazard (Zhang et al, 2010). Even though climate change and air pollution are closely linked, they have been addressed separately in applied scientific research and political negotiations previously (Swart et al, 2004). Well-known air pollutants such as BC, which are shortlived climate forcing agents, are attracting increasing scientific interests, considering that their reduction can have both climate and health benefits, especially in developing countries with large BC emissions and relatively low abatement costs (Rypdal et al, 2009). To scientifically understand the contribution of Chinese BC emissions to both regional and global air quality, premature mortality and climate effects, and to build the scientific foundation for bringing out global cost-effective measures to achieve simultaneous control of climate change and air pollution, it is significant to develop complete and reliable tempo-spatial Chinese BC emission inventories
