Research Questions for the Midterm CAFE Review: The Fuel Efficiency Gap

This is the second in a series of blog posts by RFF’s transportation team that will address some of the key research questions for the midterm CAFE review. As the first post in this series described, US standards for passenger vehicle fuel economy and greenhouse gas emissions are slated to tighten steeply. By 2025, the […]

Gauging the Distributional Consequences of Public Policies

Although we know that public policies have different effects across a population, examination of the distributional effects has been largely neglected. Instead, the principal criteria now used in public policy assessments are measurements of net benefits, which estimate the sum of a policy’s benefits minus its costs, and benefit–cost ratios. But using these criteria can […]

Research Questions for the Midterm CAFE Review

Our country is about to enter the most important period this decade for the future of transportation and its associated greenhouse gas (GHG) emissions. Fuel economy and GHG standards for both light-duty vehicles and heavier trucks are slated to tighten, reducing not only oil use but also GHG emissions. There is significant uncertainty about how […]

Update on Ending the Export Ban: What It Means for US Gasoline Prices

Data aficionados among our readers will appreciate that it is best to analyze price movements using as disaggregated data as possible, both temporally and spatially. In the original version of our recent issue brief, we used annual data.  But with more time to acquire data, we found monthly data series.  Importantly, these new data include […]

Using Natural Gas to Lower Fuel Costs

With low-cost, abundant natural gas now available in the United States and the promise of new fuel and vehicle technologies on the rise, an opportunity may soon exist for industry (and consumers) to expand the use of natural gas in the form of a liquid fuel for passenger cars and trucks. In new research, RFF’s […]

Ending the Export Ban: What It Means for US Gasoline Prices

Last week, top Democrats on the Senate Energy and Natural Resources Committee requested a comprehensive review of what would happen—in terms of energy prices, consumer prices, and more—if the US were to lift its ban on oil exports. In a new RFF issue brief, together with Stephen Brown, Charles Mason, and Jan Mares, we tackle […]

How Have Recent Fuel Economy and GHG Standards for New Passenger Vehicles Affected the US and European Markets?

In the second post of a two-part series, RFF Fellow Joshua Linn examines how recent standards have affected the type and rate of technology adoption in new vehicles. Click to read the first installment. Concerns about global warming and energy security have caused many countries to tighten passenger vehicle standards for greenhouse gases and fuel […]

Understanding the Tradeoffs of CAFE Standards

In the first of a two-part series, RFF Fellow Joshua Linn explains how vehicle manufacturers respond to tightening fuel economy standards. Click to read the second installment. Though the Corporate Average Fuel Economy (CAFE) standards have been regulating the fuel economy of US vehicles since 1978, the levels of the standards were pretty much flat […]

Market Shares and Technology Driving Up Fuel Economy in New Vehicles

From the late 1980s to about 2004, the average fuel economy of new passenger vehicles in the United States declined gradually. Then, over the past 10 years, fuel economy jumped suddenly, up almost 20 percent by 2012. In a recent paper, my colleague Shefali Khanna and I ask which end of the production line explains […]

Shale Gas Development Linked to Traffic Accidents in Pennsylvania

Pennsylvania has seen the development of more than 5,000 7,000 hydraulically fracked shale gas wells since 2004. The fracking process itself requires water and other liquids to work, not to mention rigs, other equipment, and labor, to fully develop the well. The water used in hydraulic fracturing is primarily brought to and from a well via […]
