Appropriately designed renewable support policies can play a leading role in promoting renewable expansions and contribute to low emission goals. Meanwhile, ill-designed policies may distort electricity markets, put power utilities and generation companies on an unlevel playing field and, in turn, cause inefficiencies. This paper, forthcoming in IEEE Transactions on Power Systems, proposes a framework to optimize policymaking for renewable energy sources, while incorporating conflicting interests and objectives of different stakeholders.

This report analyzes a key issue in U.S. transportation policy: the energy efficiency gap. We discuss the market failures that cause it, and recommend that the Biden administration continue the longstanding practice of incorporating private fuel savings in any evaluation of the costs and benefits of stronger standards for cars and trucks.

We conducted a large-sample global survey on climate economics, which we sent to all economists who have published climate-related research in the field’s highest-ranked academic journals; 738 responded. To our knowledge, this is the largest-ever expert survey on the economics of climate change. The results show an overwhelming consensus that the costs of inaction on climate change are higher than the costs of action, and that immediate, aggressive emissions reductions are economically desirable.

This Issue Brief highlights key takeaways from the survey. A more detailed report is available here.

The Covid-19 pandemic has led federal, state, and municipal policymakers to adopt a number of measures that suspended, delayed, or relaxed a variety of environmental safeguards. Our report analyzes these pandemic-related policy shifts and their impacts on public health and the environment. We also provide guidance on how agencies can increase transparency about these actions, counteract detrimental effects, and preemptively create guidelines to improve responses in a future emergency.
