EPA proposes stringent new emissions standards for light-, medium-, heavy-duty vehicles for MY 2027 and beyond

Green Car Congress

The US Environmental Protection Agency (EPA) announced two new proposed federal emissions standards spanning light-, medium- and heavy-duty vehicles for model year 2027 and beyond. The light-duty vehicle category includes passenger cars and light trucks consistent with previous EPA criteria pollutant and GHG rules.

Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).
