Abstract
There are significant co-benefits to reducing black carbon emissions for air quality, human health and the climate; yet the pollutant has not yet received sufficient policy attention in China. Overall, realizing co-benefits is complicated by the fact that climate and air quality policy goals have been pursued separately from each other. In this article, we explore the current policy and legal status of black carbon emissions across the domains of air pollution prevention and control, and climate change with a view to identify synergies and opportunities for an integrated approach. We suggest three ways to strengthen the policy, legal and institutional nexus of air pollution and climate change to reduce black carbon emissions in China: improving scientific knowledge and the science-policy interface, increasing policy and legal connections between air quality and climate portfolios, and enhancing institutional linkages. For instance, we argue that more interdisciplinary cooperation and improvements to the black carbon inventory as well as a closer science-policy relationship are necessary. From a legal and policy angle, we identify clear openings through which to integrate reduction of black carbon emissions into the air pollution prevention and control agenda. Institutionally, the recent government reform brings air quality and climate portfolios under the supervision of the same ministry but their integration is still to be ensured. In addition, vertical linkages between different levels of environmental governance - central, provincial and municipal - need to be addressed.
