    Recalibrating the Discount Rate for the Social Cost of Greenhouse Gases (Working Paper)

    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 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 working paper 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.

  • Comments to EPA on Proposed Rescinding of Clean Air Act Benefit-Cost Rule

    In May, EPA announced its intention to rescind a 2020 rule entitled "Increasing Consistency and Transparency in Considering Benefits and Costs in the Clean Air Act Rulemaking Process." Policy Integrity submitted comments in support of this decision based on the view that the 2020 rule is unnecessary, unsupported by any evidence of need, and inconsistent with best practices for cost-benefit analysis. We attached joint comments that Policy Integrity submitted during the original rulemaking which made these arguments in addition to demonstrating specifically how the rule broke from cost-benefit best practices by (1) devaluing indirect benefits, (2) subjecting benefit calculations to stricter standards than cost calculations, and (3) raising the bar for evidence of causality in a manner that excludes studies highly significant to EPA’s cost-benefit analysis.
