- Wisdom of the Experts – The social cost of carbon (SCC) and the climate-economic models underlying this prominent US climate policy instrument are heavily affected by modeler opinion and therefore may not reflect the views of most climate economists. To test whether differences exist, we recalibrate key uncertain model parameters using formal expert elicitation: a…
- Implementing NEPA in the Age of Climate Change – Under the National Environmental Policy Act, agencies must consider the environmental impacts of major federal actions before they can move forward. But agencies frequently downplay or ignore the climate change impacts of their projects in NEPA analyses, citing a slew of technical difficulties and uncertainties. This article, published in the…
- Gauging Economic Consensus on Climate Change – Issue Brief – 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…
- Broadening the Use of the Social Cost of Greenhouse Gases in Federal Policy – …government should apply the social cost of greenhouse gases beyond regulatory cost-benefit analysis. It is organized under the framework of “decision-making, budgeting, and procurement” laid out in the President’s executive order, identifying a number of relevant actions—like environmental reviews conducted under NEPA and the assessment of royalty rates for federal…
- Strategically Estimating Climate Pollution Costs in a Global Environment – …Working Group on the Social Cost of Greenhouse Gases provides compelling justifications to focus on global estimates. Based on a wide range available evidence, the Working Group should consider recommending a domestic valuation of at least 75% or more of the global values for optional use as a lower-bound estimate…
- About Time – …appropriate for calculating the social cost of greenhouse gases could be conservatively estimated as between 0.5%-2.5%, with a central estimate of 1.5%. Agencies should follow the Interagency Working Group’s guidance on applying new social cost of greenhouse gas estimates based on updated discount rates—and will need to justify their choices,…
- Expert Elicitation and the Social Cost of Greenhouse Gases – …Working Group on the Social Cost of Greenhouse Gases can use the findings from expert elicitations to improve the U.S. federal government’s social cost of greenhouse gas estimates, which are used in regulatory cost-benefit analysis and other policy contexts. Our report highlights several component updates, incorporating data from expert elicitations,…
- Playing with Fire – …regulations or administrative actions that apply the Working Group’s social cost valuations. Given its expertise, the Working Group should consider providing such responses now, so that agencies can then incorporate them into future actions. This working paper offers a blueprint for those responses.
- Climate-Society Feedback Effects – …is critical to understand social-ecological system 〈SES〉 feedbacks, including how humans change the climate by reacting to a changing climate. Building on recent scholarly work on the topic, this article describes SES interactions and how they can be incorporated into climate policy tools such as the social cost of carbon.…
- Costs, Confusion, and Climate Change – …that a “marginal abatement cost” (MAC) could be used as an alternative to the social cost of carbon (SCC). This article provides conceptual clarity about these metrics, focusing on how a MAC-based threshold could sensibly be used in climate policy, and explaining why it is not a substitute for the…
