Investigated the impacts of updating three standards in Mexico to align with the international best practices employed in the rest of North America: gasoline and diesel sulfur standards, passenger vehicle emissions standards, and truck and bus emissions standards.
Actions that reduce or eliminate HFC-134a emissions can make an important contribution toward lowering the overall climate impact of the global auto fleet. This paper assesses alternate refrigerant emissions and their climate impacts.
This paper was submitted to the UNECE GRPE informal subgroup on the development of a worldwide harmonized light vehicles test procedure (WLTP-DTP) on the issue of inertia classes to be used in the development of the WLTP.
Case study demonstrates how metrics that include vehicle and/or fuel weight could relax incentives for manufacturers to devote technological improvements to reducing fuel consumption rather than boosting performance.
Surveys the range of test cycles used to evaluate the efficiency of vehicles—including passenger cars and trucks, motorcycles, heavy-duty trucks and buses, and marine vessels—in order to inform ICAO discussion of a CO2 certification procedure.
