Back in April, the Environmental Protection Agency (EPA) announced new vehicle emissions standards for new light- and medium-duty vehicles produced between the 2027 and 2032 model years, proposing some of the strictest emissions standards yet. The new standards are intended to accelerate all-electric vehicle adoption. However, despite its aggressive EV transition plans, GM is now pushing back on the EPA’s latest proposal, stating that the new rules could pose a challenge, even in light of GM’s stated goal of eliminating tailpipe emissions from its light-duty vehicles by the 2035 calendar year.
Per a recent report from Reuters, GM submitted comments to the EPA outlining its concerns with the regulatory body’s latest emissions proposal. According to GM, there are six state and federal regulations that “could require each automaker to exceed 50 percent EVs in at least a dozen vehicle averaging sets” by 2030. Additionally, GM cites a “potential lack of clarity or a lack of coordination across the agencies” that could hinder automakers’ compliance year to year, despite meeting the overall EV targets.
GM told the EPA that while it was confident it would reach 50 percent EV sales by 2030 and 100 percent by 2035, its “ability to meet such precise EV shares in every applicable averaging set in each model year is less clear.”
The EPA previously announced standards for the 2027 through 2032 model years that include an 18-percent combined fleet year-over-year reduction in C02 emissions for the 2027 model year, followed by further cuts each subsequent year, including a 13-percent cut for 2028, a 15-percent cut for 2029, an 8-percent cut for 2030, a 9-percent cut for 2031, and an 11-percent cut for 2032.
The EPA projects that the new rules could prevent 7.3 billion tons of carbon emissions by 2055. Additionally, the EPA projects that the proposed standards could result in 60 percent of new vehicles sold by 2030 to be all-electric, rising to 67 percent by 2032.
Just last week, the Alliance for Automotive Innovation, an automotive lobbying group of which GM is a member, published a series of suggested changes to the new EPA standards. GM has also stated that it supports the “original goals” outlined by the Biden administration calling for 50 percent of new vehicle sales being EVs or plug-in hybrids by 2030.
