    Expert Elicitation and the Social Cost of Greenhouse Gases

    The Interagency 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, that the Working Group should consider during its current update of the social cost of greenhouse gas estimates.

    Recalibrating the Discount Rate for the Social Cost of Greenhouse Gases

    In light of recent evidence, a new range of discount rates 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, including any departures from prior practices.

  • Strategically Estimating Climate Pollution Costs in a Global Environment Cover

    Strategically Estimating Climate Pollution Costs in a Global Environment

    Debate has reemerged about whether federal agencies’ policy analyses should focus on those climate pollution costs that will occur only within U.S. borders, rather than on the full global valuation of climate damages. The Interagency 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 5 a lower-bound estimate in sensitivity analysis.

  • Broadening the Use of the Social Cost of Greenhouse Gases in Federal Policy Cover

    Broadening the Use of the Social Cost of Greenhouse Gases in Federal Policy

    Our report highlights numerous areas in which the federal 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 land-management. In short, application of the social cost of greenhouse gases would be extremely beneficial for any executive branch decision with significant greenhouse gas implications.

  • Comments to SEC on Climate Change Disclosure

    Climate change presents grave risk across the U.S. economy, including to corporations, their investors, the markets in which they operate, and the American public at large. The Securities and Exchange Commission (SEC) recently requested public input on climate change disclosures, posing several questions related to the development of new disclosure regulations and the enforcement of existing regulations. We worked with several partners to submit comments to the SEC, providing 15 major recommendations.

  • Policy Integrity and Partners Form New Initiative on Climate Risk and Resilience Law

    As the climate crisis intensifies, it is crucial that policymakers strengthen protections from the dangers of climate change to our nation’s financial system and the millions of people who rely on it to sustain the American economy. The Institute for Policy Integrity, alongside several partners, has founded the Initiative on Climate Risk and Resilience Law to advocate for smarter policies on this issue.

  • Comments to New Jersey on Solar Incentives

    The New Jersey Board of Public Utilities (BPU) released a straw proposal for its Solar Successor Program. We submitted comments addressing a question about solar projects' potential benefits to environmental justice (EJ) communities. Our comments encourage BPU to consider the inclusion of an environmental justice adder and reommend that BPU explore an adder that would deliver material benefits to EJ communities.

  • Comments to DOE on Process Rule for New Energy Conservation Standards

    The Department of Energy proposed revisions to its procedures and policies for considering new energy conservation standards across a range of consumer products and commercial equipment. We submitted comments offering support for the proposed revisions and making additional recommendations. Our recommendations include weighing a full range of environmental and consumer effects, incorporating the consideration of distributional justice, and reviewing the selection of discount rates.

  • Comments on Greenhouse Gas Emission Offsets from Rail Tie Wind Project

    The Rail Tie Wind Project would offset approximately 900,000 metric tons of carbon dioxide emissions annually compared to typical U.S. electric generation. We submitted comments encouraging the Western Area Power Administration to provide context for those emission offsets by using the social cost of greenhouse gases.
