Major Fuel Economy Boost
Envisioned by Obama Administration
The Obama administration is considering a new fuel economy standard that would require cars and light trucks to achieve an average of 56.2 miles per gallon by 2025
, an ambitious target that would reduce greenhouse gas emissions but drive up the cost of automobiles. While still a starting point in negotiations, the new target — which was proposed during separate meetings between U.S. officials and General Motors, Ford, and Chrysler — gives an early indication of administration goals as it begins to set fuel economy standards for 2017-2025. Last year, the Transportation Department and the U.S. Environmental Protection Agency (EPA) said they would look at a standard between 47 and 62 mpg; today’s fuel economy standard is 25 mpg and will change to 35.5 in 2016. According to a government analysis, achieving the upper end of the 2025 target would require that half of the nation’s new vehicles be gas-electric hybrids and would add $2,100 to $2,600 to the price of a car. Last week, a group of moderate Republicans — including four former EPA administrators — urged the administration to impose tougher emissions standards
for cars and light trucks.
