US EPA Weakens Auto Emissions Standards
4 Dec
Summary
- Transportation emissions are the biggest source of greenhouse gases in the US.
- New standards propose 34.5 mpg by 2031, down from 50 mpg.
- Policy change may increase fuel costs and pollution for families.

Transportation is the largest contributor to U.S. greenhouse gas emissions, representing over 28% in 2022. The National Highway Traffic Safety Administration has proposed significantly less stringent fuel efficiency standards for automakers. The revised target is approximately 34.5 miles per gallon by the 2031 model year, a substantial reduction from the prior 50 miles per gallon goal.
Furthermore, the administration is discontinuing a program that allowed manufacturers to purchase credits from more efficient carmakers, like Tesla. This program was cited as artificially supporting the electric vehicle market. Critics argue these changes will lead to increased greenhouse gas emissions and higher expenses for families at the pump.
Environmental advocates warn that loosening these standards will prolong the presence of polluting vehicles, negatively impacting public health, especially for vulnerable populations. However, some industry representatives, such as Ford's CEO, view the revised regulations as appropriate, stating they align with current consumer preferences and represent a prudent adjustment for the automotive sector.
