International Comparison of Brazilian Regulatory Standards for Light-Duty Vehicle Emissions

This white paper compares regulatory standards for light-duty (LD) vehicle emissions in the U.S., Europe, and Brazil. The standards examined are Brazil's Programa de Controle de Poluição do Ar por Veículos Automotores (PROCONVE) L6 standards, U.S. Tier 2 and 3, and EU Euro 6 programs. First the authors look at motor vehicles and air quality in Brazil and provide a characterization of the Brazilian LD vehicle fleet. Data includes annual average fine particulate matter (PM2.5) concentrations in 40 Brazilian cities. In all cities except one, PM2.5 levels exceed World Health Organization (WHO) air quality guidelines. Next, regulatory standards are compared between European programs and the U.S., examining emission limits, regulated pollutants, durability requirements, evaporative emission standards, dynamometer test cycles, and on-board diagnostic system specifications. Finally, areas where PROCONVE L6 lags behind international best practices are outlined along with policy recommendations to improve PROCONVE L7.
