The paper examines an integrated framework to understand the emissions impact of unilateral overlapping policies within a carbon-pricing system. “Internal carbon leakage” captures emissions displacement within the system (e.g., due to greater product imports from a neighbouring country). The waterbed effect captures the policy’s interaction with the system’s overall emissions cap. Current market rules in the reformed EU ETS, California’s carbon market and RGGI feature “punctured” waterbeds that allow overlapping policies to affect aggregate emissions. The paper presented in this Research Seminar presents simple formulae to estimate internal carbon leakage for different types of policy such as a carbon price floor (perhaps with a border tax adjustment), an energy efficiency program, and renewables support. The sign and magnitude of the climate benefit from an overlapping policy varies widely depending on its design, location and timing. Punctured waterbeds raise the stakes: well-designed overlapping policies can be much more climate-effective but others now backfire.
Environmental, energy, and ecological problems have grown faster than their solutions. Economists have an important role to play to address these issues by using the latest science, rigorous methods and innovative policy solutions. The SWEEEP webinar series aims to convene the academic community to contribute to the scientific, economic, and policy discourses on important environmental and energy issues.
The seminar presentations are scheduled to last 60 minutes, with questions at the end.
The European Institute on Economics and the Environment is a partnership between Resources for the Future and Foundation CMCC. EIEE’s impartial economic and environmental research aims to facilitate the transition to a sustainable, inclusive society.

The ZEW – Leibniz Centre for European Economic Research is a leading German economic policy institute and a member of the Leibniz Association. ZEW's applied research aims to study and help design well-performing markets and institutions in Europe. In particular, it seeks to understand how to create a market framework that will enable the sustainable and efficient development of European economies.

The Centre for Energy Policy and Economics (CEPE) was established in 1999 to complement the natural science and technical-oriented disciplines at ETH Zurich, by contributing to research and teaching in energy policy and economics. Through rigorous application of modern empirical methods, the goal of CEPE is to make critical contributions to the design and evaluation of energy and climate policy instruments.
