New Fuel Economy Standards—Keeping Up with the Real World?

In April, the U.S. Department of Transportation proposed a rule to ramp up fuel economy (CAFE) standards over the years 2011-2015, reaching an average of 31.6 miles per gallon in 2015. The rule represents the first phase in implementing the requirement in the Energy Independence and Security Act of 2007 that new cars and trucks reach at least 35 miles per gallon by 2020, an increase of 40% over today's levels.

Fuel Economy Rule Promises Substantial Efficiency Gains Fumbles on Climate Protection

Washington, D.C. — The American Council for an Energy-Efficient Economy (ACEEE) expressed optimism regarding the car and light truck fuel economy requirements proposed today by the U.S. Department of Transportation (DOT), but denounced DOT's continuing attempts to interfere with states' climate protection efforts. The DOT rule would be the first step towards meeting the increase in CAFE (Corporate Average Fuel Economy) standards mandated by the Energy Independence and Security Act of 2007.

Natural Gas and Hybrid Vehicles Still Stars Diesels Still No-Shows in Annual Ranking of Top Eco-Friendly Vehicles

Washington, D.C. — With the auto world focused on fuel efficiency in the face of $100-per-barrel oil, new fuel economy requirements, and concern about climate change, the American Council for an Energy-Efficient Economy (ACEEE) today named the year's "greenest" and "meanest" vehicles, along with environmental scorings of all model year 2008 cars and passenger trucks. This announcement marks the eleventh year ACEEE has published its widely-respected rankings.

CAFE Bills Brewing in Congress

At long last, an increase in car and light truck fuel economy standards has passed the U.S. Senate. The Senate energy bill (an amendment to H.R.6) raises the standards to 35 miles per gallon by 2020—up from today’s average of 24.6 miles per gallon. But the bill also hands the Department of Transportation discretion to lower these targets if they’re not “cost-effective,” a major weakness given DOT’s record of timid fuel economy rulemaking.

CAFE Percolating Again

Prospects for substantially higher vehicle fuel economy standards are looking up, thanks in part to the White House. President Bush’s State of the Union proposal to reduce gasoline consumption twenty percent by 2017 was met with skepticism by many due to its heavy reliance on unspecified “alternative” fuels.

Trends Away From Efficiency

A simple equation can help explain America's increasing use and dependence on oil: (stagnating fuel economy) * (increasing miles traveled) = (rising petroleum use).

Attribute-Based CAFE Standards: A Primer

 Several current legislative proposals for increasing car and light truck fuel economy requirements call for changing the structure of the policy to one based on "vehicle attributes." What exactly does that mean?
