U of Toronto study finds US electrification of LDV fleet not a silver bullet for tackling climate change in vehicle sector

Green Car Congress

A new study by researchers at the University of Toronto has found that current US policies are insufficient to remain within a sectoral CO 2 emission budget for light-duty vehicles that is consistent with preventing more than 2?°C GtCO 2 (28% of the projected 2015–2050 light-duty vehicle fleet emissions). C global warming.

EPA: US GHG emissions up 6% in 2021 from 2020

Green Car Congress

Fuel economy of light-duty vehicles is another important factor. The decline in new light-duty vehicle fuel economy between 1990 and 2004 reflected the increasing market share of light-duty trucks, which grew from about 29.6% Emissions from petroleum consumption for transportation decreased by 4.0%

EPA, NHTSA issue One National Program Rule; EPA withdraws CA waiver for GHG and fuel economy

Green Car Congress

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. Earlier post.)

UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

The gasoline direct injection (GDI) engine is one of the most prominent technologies car manufacturers adopted to achieve the fuel economy and carbon dioxide emission goals established in 2012 by the US Environmental Protection Agency. A strong absorber of solar radiation, black carbon exhibits significant climate warming properties.

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

Green Car Congress

In the US, Model Year (MY) 2018 vehicle fuel economy was 25.1 Since MY 2004, CO 2 emissions have decreased 23%, or 108 g/mi, and fuel economy has increased 30%, or 5.8 Average estimated real-world CO 2 emissions are projected to fall 6 g/mi to 346 g/mi and fuel economy is projected to increase 0.4

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e., passenger cars and light-duty trucks) increased by 48% from 1990 to 2019; VMT by medium- and heavy-duty trucks increased 109% over the same period.

Researchers find consumers compensate for fuel-efficient car by buying bigger second vehicle; losing 60% of fuel economy savings

Green Car Congress

An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%.
