To support policy makers, port officials, and key researchers in formulating a pragmatic and effective work plan for controlling air emissions from shipping and ports, the Natural Resources Defense Council (NRDC) organized a series of roundtable meetings between international port experts and key stakeholders, including senior officials and researchers from the transport, maritime, and environmental protection agencies in the national government and key port provinces and cities, as well as port officials and academics in Beijing, Tianjin, Shanghai, and Guangzhou on September 21-25, 2015. The meetings were planned to share how air pollution from shipping and ports are controlled and mitigated in the U.S. and EU, and to discuss the range of measures that can be taken to enable the Chinese port and shipping sectors to maintain growth while simultaneously reducing air emissions from these activities. This document summarizes the insights shared during these meetings.
