PROCONVE

Programa de Controle da Poluição do Ar por Veículos Automotores - PROCONVE (automobiles) and PROMOT (motorcycles) is a division of IBAMA that regulates vehicular emissions in Brazil.

The European emission standards (used in many Latin American countries) are taken as a reference.

Standards for light vehicles are indicated by the letter 'L'. For heavy vehicles, 'P' is used (pesados). A number indicates an increasingly stricter norm for each class. Currently Ln pairs up with Pn+1.
