International comparison of Brazilian regulatory standards for light-duty vehicle emissions

This paper aims to inform the next phase of PROCONVE for LD vehicles by assessing important components of PROCONVE L6 and their relative strengths and weaknesses compared with similar programs in the United States and the European Union. The U.S. and EU programs were selected for this comparison because they have progressed furthest in controlling emissions from motor vehicles, and are often models for other countries implementing vehicle emission control programs.
