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. 2013a; Zhao et al. 2013b; Lei et al. 2013; 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 additionally 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 & TechnologyAnother paper led by Zhao 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.

Zhao continues to lead emissions research in the China Project as a collaborating professor based in the School of Environment, Nanjing University (Zhao et al. 2015aZhao et al. 2015bCui et al. 2015Zhao et al. 2014Zhao et al. 2013c). The emission inventories developed and continually refined by Zhao and colleagues are a central element of China Project initiatives integrating most of the Project's major research capacities in assessment of the total costs and benefits of emission control and energy policy options in China. These efforts are described in a separate research page on the China Project's recent book Clearer Skies over China and continuing interdisciplinary research.

Recent visiting scholars to the China Project have contributed collaborative research on other dimensions of emissions and their environmental effects, including WANG Haikun of the School of Environment of Nanjing University (Wang et al. 2015Zhang et al. 2015Zhang et al. 2014) and WANG Shuxiao of the School of Environment of Tsinghua University (Wang et al. 2014).
