SEMARNAT to existing emissions standards regulating particulate matter (PM), nitrogen oxides (NOX), hydrocarbons (HC) and carbon monoxide (CO) from heavy-duty diesel

Jakarta’s expanding fleet of motor vehicles is a key target of urgently needed actions to curb the city’s dangerous air pollution. This briefing paper highlights technologies and

The introduction of mandatory CO2 standards for passenger cars in the European Union led to a significant decrease in the level of CO2 emissions for new vehicles, as well an increased deployment of vehicle efficiency technologies.

As regulatory agencies in the U.S. work on the second phase of heavy-duty vehicle greenhouse gas (GHG) and efficiency standards, one of the key decisions they face concerns the regulatory certification pathways.

This paper assesses the status of fuel consumption (FC) levels and fuel efficiency technology adoption in China’s light commercial vehicle (LCV) market in 2010, focusing on the differences among vehicle sub-categories and manufacturers.

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

A detailed but accessible overview of the concept of indirect land use change and the way that ILUC emissions are estimated. Identifies factors that determine the size of ILUC effects when biofuel demand increases and shows how they are handled in the most important models used in the U.S. and EU.

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.
