The “more stringent” standards released by the agency would induce a 56% decrease in greenhouse gas emissions for light-duty vehicles as well as a 44% decrease for medium-duty vehicles, while similar standards were introduced for heavy-duty vehicles. The regulations would seek to change market conditions such that electric vehicles constitute two-thirds of new sales for light-duty vehicles and nearly half of new sales for medium-duty vehicles by 2032.
“By proposing the most ambitious pollution standards ever for cars and trucks, we are delivering on the Biden-Harris administration’s promise to protect people and the planet, securing critical reductions in dangerous air and climate pollution and ensuring significant economic benefits like lower fuel and maintenance costs for families,” EPA Administrator Michael Regan said in a press release. “These ambitious standards are readily achievable thanks to President Biden’s Investing in America agenda, which is already driving historic progress to build more American-made electric cars and secure America’s global competitiveness.”
The proposals follow aggressive regulations and legislative packages from the White House over the past two years in favor of electric vehicles and an overall transition toward renewable energy. The Biden administration, which has established a “whole-of-government effort” to reduce carbon emissions and incentivize renewables, has also introduced new emissions rules for gas stoves, air conditioners, and mobile homes.
