Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.

NO x is a precursor for both ground level ozone and secondary PM 2.5 Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

Development of sustainable communities strategies can also provide an opportunity for associated criteria pollutant emission reductions that will be needed to attain air quality standards for ozone and particulate matter as well as reduce near-roadway exposures.

On the production side, options exist for improving technologies in terms of new feedstocks and conversion technologies as well as more efficient use of biomass. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials.

Next-generation standards would target new reductions in emissions of NO x and non-methane hydrocarbons (HC), which are precursors to ozone and secondary particulate matter. Baseline and Accelerated Policy timeline for light-duty vehicles. exposure in urban areas will increase 50% by 2030, compared to 2013. Chambliss et al.
