Accelerate deployment of tighter diesel fuel quality standards to reduce emissions of black carbon and other short-lived climate pollutants


Extending the vehicle emissions and fuel-quality standards already in force in the largest vehicle markets throughout the rest of the world could reduce the number of premature deaths caused annually by vehicle fine particle emissions by 75% in 2030. Additionally, doing so would have the added benefit of reducing near-term climate impacts through reductions in black carbon and other short-lived climate pollutants, to the equivalent of 710 million metric tons of CO2 annually.

Status of deployment:

Historically, technical interventions to control diesel black carbon emissions in developed countries have relied on fuel quality improvements and vehicle emissions standards.  Black carbon emissions are projected to decline due to policies implemented in the United States, Canada, Europe, and Japan; however, global emissions are projected to increase in the next decade as vehicle activity increases, particularly in East and South Asia.
