EPA trends report finds MY 2021 fuel economy remained flat at a record high while CO2 levels hit new low

Green Car Congress

The US Environmental Protection Agency (EPA) released its annual Automotive Trends Report , which shows that model year (MY) 2021 vehicle fuel economy remained at a record high—but flat with MY 2020 fuel economy—while CO 2 emission levels reached a new record low. Estimated real-world fuel economy and CO 2 emissions.

TRUE US database shows emissions characteristics of US fleet

Green Car Congress

To complement its work on real-world emissions in Europe, TRUE has compiled remote sensing data from the states of Colorado and Virginia and the University of Denver to investigate the emissions of US light-duty vehicles. Measured deterioration rates are much higher than projections submitted to the US EPA by manufacturers.

EPA’s annual automotive trends report shows slight increase in fuel economy from MY2017 to MY2018

Green Car Congress

In model year 2018, the average estimated real-world CO2 emission rate for all new vehicles fell by 4 grams per mile (g/mi) to 353 g/mi, the lowest level measured since 1975, when EPA data collection began. Since MY 2004, CO 2 emissions have decreased 23%, or 108 g/mi, and fuel economy has increased 30%, or 5.8 Source: EPA.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications. trillion) in 2014.

EPA: preliminary data show average fuel economy of new light-duty vehicles reached a record high of 25.7 MPG in 2020

Green Car Congress

The period from 1975–1987 was marked by a rapid increase in average fuel economy, followed by a gradual decrease in fuel economy from 1988–2004. Other major highlights from the Trends Report include: MY 2019 new vehicle estimated real-world CO 2 emissions increased slightly from the record low for MY 2018. Fuel economy decreased by 0.2
