Fourteen U.S. states recently pledged to adopt limits on automobile greenhouse gases (GHGs) per mile in an effort to reduce GHG emissions. We show that, because of interactions between this effort and the federal CAFE standard, 70-80 percent of the emissions reductions from new cars in adopting...

Fourteen U.S. states recently pledged to adopt limits on greenhouse gases (GHGs) per mile of light-duty automobiles. Previous analyses predicted this action would significantly reduce emissions from new cars in these states, but ignored possible offsetting emissions increases from policy-induced...

We propose a novel mechanism for coalitional policies in a climate coalition. In our proposed setup, national (unilateral) and federal (multinational) emission policies coexist. A joint federal institution, appointed by all members, sets a joint emission policy for its members and must attain...
