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.
New Fuel Economy Standards & Other Energy Efficiency Policies Coming to a Vote Soon on Capitol Hill!
After months of work on its substance, and weeks of speculation about which provisions would ultimately be included, an energy bill is expected to be unveiled today.
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.
Washington, D.C. — Amid numerous industry claims of eco-friendly vehicles and rising public concern about U.S. oil dependence, 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 2007 cars and passenger trucks. This announcement marks the tenth year ACEEE has published its widely respected rankings.
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.
A simple equation can help explain America's increasing use and dependence on oil: (stagnating fuel economy) * (increasing miles traveled) = (rising petroleum use).

Washington, D.C. — Plug-in hybrid vehicles could contribute greatly to reducing automobile oil consumption and emissions, but reaching those goals requires major progress in key areas. According to a report released today by the American Council for an Energy-Efficient Economy, the environmental and economic appeal of plug-in hybrid vehicles will depend heavily upon cleaner power sources and further battery advances.
