The paper shows that economic models of climate change produce climate dynamics inconsistent with current climate science models: (i) the delay between CO2 emissions and warming is much too long and (ii) positive carbon cycle feedbacks are mostly absent. These inconsistencies lead to biased economic policy advice. Controlling for how the economy is represented, different climate models result in significantly different optimal CO2 emissions. A long delay between emissions and warming leads to optimal carbon prices that are too low and attaches too much importance to the discount rate. Similarly, the authors find that omitting positive carbon cycle feedbacks leads to optimal carbon prices that are too low. They conclude it is important for policy purposes to bring economic models in line with the state of the art in climate science and we make practical suggestions for how to do so.
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.
