Transport sector policies already contribute to moderating greenhouse gas emissions from road vehicles. They are increasingly designed to contribute to overall societal targets to mitigate climate change. While abatement costs in transport are relatively high, there are plausible arguments in...

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

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...
