PROCONVE
Open-knowledge reference entry
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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “PROCONVE”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 10, 2025. The linked authority identifier is Q10354379. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012, 2015, 2022 and 2023.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
