This brief presents the technical details and benefits of leapfrogging to Euro VI heavy-duty emission standards and Euro 6 light-duty emission standards rather than progressing through Euro 5/V.

Heavy Duty Vehicles conforming to Euro IV and V standards frequently show poor real-world NOx emissions performance. Evidence indicates that new certification protocols in Euro VI resolve this problem, and Euro VI-compliant HDV NOx emissions meet expectations.

On December 1, 2014, COMARNAT, the national regulatory committee of the Secretariat of Environment and Natural Resources (SEMARNAT), approved a proposed update by
SEMARNAT to existing emissions standards regulating particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC) and carbon monoxide (CO) from heavy-duty diesel

This study, a meta-analysis of PEMS data from EU (Euro 6) and US (Tier 2 Bin 5/ULEV II) diesel passenger cars, documents the wide discrepancy that exists between official certification or type-approval emissions of nitrogen oxides (NOx) from new diesel passenger cars and actual NOX emissions from those vehicles during real-world, everyday operat

Mexico is planning to revise its existing emissions standards for diesel heavy-duty vehicles (HDVs). The existing regulation, Norma Oficial Mexicana 044 (NOM 044), requires new vehicles to meet either U.S. Environmental Protection Agency (EPA) 2004 or Euro IV standards.
