Relaxing New Vehicle Fuel Efficiency Standards Sparks Environmental Controversy

On December 3 local time, U.S. President Donald Trump announced the termination of stringent fuel economy standards established during the Biden administration. The new vehicle fuel efficiency requirement for 2031 will be relaxed from 4.7 liters per 100 kilometers to 6.9 liters per 100 kilometers. This move has drawn strong opposition from environmental organizations. Transportation is the largest source of greenhouse gas emissions in the United States, accounting for 25%-30% of total emissions. Critics argue the policy will increase greenhouse gas emissions, threaten public health, and cause the U.S. to fall behind in the race for green automotive technology.
