The United States Environmental Protection Agency is proposing new and significantly more stringent vehicle emissions rules that would make electric vehicles up to 67 percent of light-duty model sales by the 2032 model year. The EPA projects that this would reduce the fleet average greenhouse gas emissions by 56 percent versus the 2026 standards. The EPA projects these changes would reduce oil imports by 20 billion barrels and save between $850 billion and $1.6 trillion from 2027 to 2055.
The proposed emissions regulation changes for light- and medium-duty models would take effect for the 2027 model year and run through 2032. By the end, CO2 emissions would fall to 82 grams per mile. The required reductions would happen year-by-year. This would include drops of 18 percent in 2027, 13 percent in 2028, 15 percent in 2029, 8 percent in 2030, 9 percent in 2031, and 11 percent in 2032.
