Abstract:

Controlling emissions from the in-use fleet, particularly from high emitters and older vehicles, can immediately alleviate urban air pollution. As pressure to address China's air quality issues builds, Guangdong Province has taken several steps toward that end. This report summarizes best practices for these in-use control programs, and is intended to serve as guidelines for policymakers seeking to design, implement, and improve their programs at the local level. In addition, the report evaluates in-use vehicle emission control programs in four cities in Guangdong’s Pearl River Delta region: Guangzhou, Shenzhen, Foshan, and Dongguan. The best practices discussed in this report are experiences that policymakers can learn from rather than strict rules for implementation. Effective in-use vehicle emission control is a collective result from various programs. The report concludes by suggesting detailed actions that Guangdong Province or its cities can take to enhance in-use vehicle emission control programs at the local level.
