Air Pollution and GHGs: Emissions

The China Project research on emission inventories and trends is complemented by research on atmospheric transport and chemistry described here, and atmospheric field observation described here.

Former post-docs ZHAO Yu and LEI Yu brought research capacities in bottom-up emission inventories to the China Project, and their application in analyses of environmental impacts of emission trends and controls (Zhao et al. 2014; Zhao et al. 2013a; Zhao et al. 2013b; Zhao et al. 2013c; Lei et al. 2013a; Lei 2013b; Zhao et al. 2012aZhao et al. 2012bLei et al. 2011aLei et al. 2011bZhao et al. 2011aZhao et al. 2011bZhao et al. 2011cZhao et al. 2010). Zhao continues to lead research in the China Project as a professor in the School of Environment, Nanjing University, and Lei continues to collaborate as Associate Research Fellow and Assistant Director of the Atmospheric Environmental Institute of the Chinese Academy of Environmental Planning, Beijing.

Zhao has also analyzed effects of emission control policies on acid precipitation in China, estimating how growth in NOx and other species could be canceling all benefits to acidification of China's aggressive and successful SO2 control policy (Zhao et al. 2009). The policy implications of these results brought news coverage in Environmental Science & TechnologyA newer paper by Zhao et al. shows how control of particulate matter, comprised in part of neutralizing base cations, may also limit recovery from soil and ecosystem acidification (Zhao et al. 2011b). These studies emphasize the need for a multi-pollutant perspective.

The emission inventories are part of an initiative integrating most of the China Project's major research capacities in assessment of the total costs and benefits of emission control and energy policy options in China. This new effort is described in a separate link here.
