Recent headline-worthy air pollution events across China make evident that the monitoring and regulation of pollution sources are lacking and that enforcement must be improved. Legal professionals, including judges and lawyers, as well China’s NGO community can play an important part in increasing the enforcement of environmental regulations. From November 30 to December 4, the USAID-supported US-China Partnership for Environmental Law at Vermont Law School and its local partner trained 35 judges, 19 lawyers, 7 environmental protection officers, and 20 NGO representatives on the latest legal and policy developments. In-depth case studies were used to illustrate common errors in enforcement and weaknesses in law. On the final day, NGO personnel engaged in an exercise applying the lessons learned during the training. Environmental policy and law reforms are happening rapidly in China and trainings like this help to provide multiple stakeholders with the tools they need to effectively engage in environmental enforcement.
