Growing uneasiness about U.S. oil dependence means interest is high once again in energy legislation and petroleum legislation in particular. Upward fuel price trends of recent months, reflecting both turmoil in the Middle East and North Africa, plus the gradual recovery of the global economy, have prompted calls for decisive action by policymakers. At such a time, it is important to be clear on the range of policy options available to address the problem and how effective these policies might be.
How does where we build our homes, businesses, and transportation infrastructure impact our energy use? A recent U.S. Environmental Protection Agency report attempts to tackle just that question. The report analyzes the energy use associated with different housing and neighborhood types. It also serves as a concise and readable primer on research related to the energy implications of “location efficiency.”
UPDATED: February 16, 2011 — Due to a mistaken vehicle emissions specification, our Greenest List inadvertently omitted the Mazda 2 (manual transmission), which beats the Chevrolet Volt by a hair. Both vehicles have Green Scores of 48. Hence this year’s Greenest List now features 13 vehicles, instead of the customary dozen. We regret the error.
Washington, D.C. — Today the U.S. Environmental Protection Agency and the Department of Transportation proposed the first-ever fuel efficiency and greenhouse gas emissions standards for medium- and heavy-duty trucks and buses. The affected vehicles, ranging from large pickup trucks to big rigs, today consume about 2.5 million barrels of oil per day, one-fifth of total transportation oil use in the U.S.
Washington, D.C. – Making good on a commitment made by President Obama in May, the Environmental Protection Agency and the Department of Transportation today announced progress in developing standards that will dramatically reduce the fuel consumption and greenhouse gas emissions of cars, SUVs, and pickup trucks in model years 2017 to 2025. The announcement follows the adoption earlier this year of standards boosting average fuel economy to 34.1 miles per gallon by 2016.
On April 1st, USDOT’s National Highway Traffic Safety Administration (NHTSA) and the EPA issued harmonized fuel economy and greenhouse gas (GHG) emissions standards for cars and light trucks of model years 2012 through 2016. The joint rulemaking marks the first major increase in fuel economy standards in three decades, and the first national GHG standards for vehicles.
