The role of fuel economy and GHG standards in reaching zero emissions by 2050


1:40pm - 3:00pm


Remote instruction


Light-duty fuel economy and greenhouse gas standards have cost-effectively improved the energy efficiency and reduced the CO2 emissions of passenger cars and light trucks. Fuel economy improvements since 1975 have saved over two trillion gallons of gasoline, and the resulting net savings have had a progressive effect on household income. As a result, the standards have enjoyed strong public support for decades. This seminar addresses how that has been possible and what the role of fuel economy and GHG standards should be in achieving deep decarbonization of light-duty vehicle transportation by 2050.
