This brief aims to highlight some of the difficulties involved in elaborating a working border carbon adjustment (BCA) regime. It demonstrates both the tensions between the various possible BCA objectives and the necessarily imperfect options that are available for bridging the tension between...

The EU is considering implementing a Carbon Border Adjustment Mechanism. To inform the policy decision, we assess eight energy-intensive trade-exposed sectors in depth to distill what their characteristics imply for the shape of an ideal mechanism. The results highlight the difficulty of finding...

For Canadian policy makers, the relatively straightforward economics of a border carbon adjustment (BCA) is complicated in practice by four challenges. First, Canadian carbon-pricing regimes have been developed from the bottom up, being primarily designed at the provincial rather than the...

Most CO2 abatement policies reduce the demand for fossil fuels and therefore their price in international markets. If these policies are not global, this price decrease raises emissions in countries without CO2 abatement policies, generating "carbon leakage". On the other hand, if the countries...

This paper studies the optimal transition from existing coal power plants to gas and renewable power under a carbon budget. It solves a model of polluting, exhaustible resources with capacity constraints and adjustment costs (to build coal, gas, and renewable power plants). It finds that optimal...

Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...
