The United States consumed more petroleum-based liquid fuel per capita than any other OECD-high-income country - 30 percent more than the second-highest country (Canada) and 40 percent more than the third-highest (Luxemburg). This paper examines the main channels through which reductions in U.S....

A low carbon fuel standard (LCFS) seeks to reduce greenhouse gas emissions by limiting a fuel producer's carbon emissions per unit of output. California has launched an LCFS for transportation fuels; others have called for a national LCFS. We show that this policy decreases production of...

Instead of efficiently pricing greenhouse gases, policy makers have favored measures that implicitly or explicitly subsidize low carbon fuels. We simulate a transportation-sector cap & trade program (CAT) and three policies currently in use: ethanol subsidies, a renewable fuel standard (RFS),...
