The Biden administration recently unveiled a new vehicle emission rule that is not as stringent as originally proposed. The rule stipulates that fuel economy will increase by 2 percent per year for passenger cars for model years 2027-2031, while light trucks will see a 2 percent increase for model years 2029-2031. These changes are expected to raise the average light-duty vehicle fuel economy to approximately 50.4 miles per gallon by 2031.
This new rule is a departure from President Biden’s initial proposal in 2022, where passenger vehicles were supposed to achieve an average of 55 miles per gallon by 2026. Additionally, the National Highway Traffic Safety Administration (NHTSA) had previously suggested raising Corporate Average Fuel Economy (CAFE) requirements by 2 percent per year for passenger cars and 4 percent per year for light-duty trucks from 2027 through 2032. However, these figures have now been scaled back significantly.
The automotive industry has welcomed the new CAFE standards, describing them as “good and appreciated.” However, there are concerns about the necessity of these standards in an industry moving rapidly towards electrification. On the other hand, some environmental groups have criticized the less stringent regulations but acknowledge that they will lead to reduced pollution and cleaner vehicles. Katherine García, the director of the Sierra Club’s Clean Transportation for All Campaign, sees the new standards as a positive step towards improving gas mileage, reducing the burden of high gas prices, and cutting the nation’s oil consumption.
Ongoing Challenges and Barriers
Despite improvements in fuel economy over the years, the United States still struggles to meet impending deadlines. The country’s preference for large trucks and SUVs has put domestic automakers at a disadvantage compared to their global competitors in terms of achieving higher miles per gallon.
The Biden administration’s new vehicle emission rule represents a compromise between industry interests and environmental concerns. While the revised standards may not be as ambitious as initially proposed, they are a step in the right direction towards cleaner and more efficient vehicles. The challenge now is for automakers to adapt to these new regulations and continue to innovate towards a more sustainable future.
