The Biden administration has announced the introduction of strict vehicle exhaust emission regulations. According to the latest regulations released by the U.S. Environmental Protection Agency (EPA), by 2026, the new rules will reduce the average vehicle emissions by nearly half compared to the current standard. According to the new regulations, 7.2 billion tons of CO2 emissions are expected to be reduced between now and 2055.
The new rules require a cap of 85 g/mile (1 mile = 1.609 km) of CO2 emissions from tailpipes in the U.S. by 2032, down from 170 g/mile by 2027 shown by the model.
According to U.S. Environmental Protection Agency modeling data, automakers may need to increase their EV sales to 56% of total U.S. sales by 2032, with plug-in hybrids accounting for 13% and conventional combustion vehicles accounting for only 29%.
Manish Babner, president of the Natural Resources Defense Council, said the new rules target the largest single source of carbon pollution in the United States and will reduce carbon sources by one-fifth. In the long run, the new rules will cut more carbon dioxide emissions than the United States combined. After the implementation of the new regulations, it will not only reduce gasoline consumption, but also reduce exhaust pollution.
"With the implementation of the new regulations, cleaner cars, more plug-in hybrids, and more electric vehicles are expected to emerge in the United States. Manish Babner told reporters.
Industry experts generally believe that although the new regulations are the strictest vehicle pollution standards in U.S. history, the Biden administration has relaxed fuel economy standards compared to previous industry expectations, a move that will slow the transition from gasoline vehicles to electric vehicles.
The EPA's initial recommendation was that battery electric vehicles would account for 60% of total vehicle sales by 2030 and 67% by 2032. Currently, electric vehicles account for less than 8% of U.S. car sales, while plug-in hybrids account for less than 2%.
