Authors Christoph Böhringer and Thomas Rutherford evaluate the efficacy of imposing carbon tariffs on U.S. imports as an alternative to U.S. participation in the Paris Agreement. The authors warn that carbon tariffs on the United States could lead to a tariff war that ultimately hurts China, in particular, and the European Union more than the United States.

In pursuit of a workable successor to the Kyoto Protocol, this study offers a framework of formulas that produces precise numerical targets for emissions of carbon dioxide (CO2) and other greenhouse gases, in all regions of the world in all decades of this century....Firms, consumers, and researchers base their current decisions to invest in plant and equipment, consumer durables, or new technological possibilities on the expected future price of carbon: If government commitments are not credible from the start, then they will not raise the expected future carbon price.
