The U.S. Environmental Protection Agency published its revised vehicle emissions requirements Monday.
The U.S. EPA’s stricter new vehicle emissions requirements call for a 5 to 10 percent increase in emissions reductions for each vehicle model year between 2023 and 2026 until an eventual fleetwide average fuel economy of 55 mpg is achieved by 2026. The proposed new rules undo the looser fuel economy/emissions standards set forth by the Trump Administration, which would have seen fuel economy standards rise by just 1.5 percent within the same timeframe, reaching an eventual average of 40.4 mpg by 2026.
These new vehicle emissions requirements are expected to speed up the adoption of EVs domestically. According to the EPA, consumer adoption of plug-hybrids and EVs will jump from a predicted 7 percent of market share in 2023 to 17 percent in 2026. The Biden Administration hopes stricter regulations on ICE vehicles, coupled with attractive incentives for union-built American EVs, will help electrified vehicles make up 50 percent of new vehicle market share by 2030.
“We followed the science, we listened to stakeholders, and we are setting robust and rigorous standards that will aggressively reduce the pollution that is harming people and our planet — and save families money at the same time,” EPA Administrator Michael Regan said in a prepared statement released Monday.
The EPA outlined slightly less strict vehicle emissions requirements back in August, which set the standard about 6 percent lower than this latest iteration of the rules. Additionally, this latest ruleset is stricter than the Obama-era emissions regulations that the Trump Administration had previously undone.
The Biden Administration previously laid out a goal for the United States to achieve net-zero carbon emissions economy-wide by no later than 2050. This is a sentiment shared by General Motors, which previously outlined a plan for its business to be fully carbon neutral by 2050 before bumping the deadline forward to 2040 earlier this year. GM will also slowly transition to a full battery-electric product portfolio over the next 15 years or so and will phase out petroleum-powered passenger cars and trucks completely by 2035.
