Specifically, in this action, NHTSA is affirming that its statutory authority to set nationally applicable fuel economy standards under the express preemption provisions of the Energy Policy and Conservation Act (EPCA) dictates that such state and local programs are preempted. criteria pollutants—is not affected by the action.

The E10 fuels were blended together in four equal parts to create the final E10 fuel. The E15 fuel was created by splash-blending denatured ASTM D4806 fuel grade ethanol with the final E10 fuel. The test fleet showed statistically significant effects for some pollutants, but not for others.

Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 Of the non-road modes (rail and air), light aircraft showed the worst performance per PKT. Chester and Horvath (2009). Click to enlarge.

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

NO x is a precursor for both ground level ozone and secondary PM 2.5 A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks. —MECA Executive Director, Rasto Brezny.

The bill also directs the President to work with the relevant Federal agencies and California to harmonize, to the maximum extent possible, the federal fuel economy standards, any emission standards promulgated by EPA, and the California standards for light-duty vehicles. light duty vehicles—e.g.,

Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. We estimate ozone and SOA formation potential. Widespread adoption of new engine technologies raises concerns about changes in emissions and their effects on air quality and the climate.
