This is a preview to a longer summary that we will publish for the 1,181-page rule finalized by the EPA, limiting greenhouse gas and criteria pollutant emissions from light- and medium-duty vehicles. If you are interested in future updates, sign up to the “5-min Monthly” below.
As in the past, the EPA rule establishes separate CO2 limits for passenger cars and light-duty trucks, as shown in the figure below. OEMs have to meet the fleet averaged requirements based on footprint curves for their vehicles sold.
Much more to come – the projected electrification, treatment of plug-in hybrids, criteria pollutant limits (NOX, PM). If interested in further updates, sign-up below.
