Together with partner groups, we submitted joint comments to the Department of Energy (DOE) on its proposed rule to strengthen energy conservation standards for consumer furnaces. Our comments applaud the agency for appropriately applying the social cost of greenhouse gases to estimate the climate benefits of the proposed standards, even though the standards would be cost-benefit justified without considering any climate benefits. We also expand upon DOE's justifications for adopting a global damages valuation and for the range of discount rates it applies to climate effects.

Together with partner groups, we submitted joint comments to the Department of Energy (DOE) on its proposed rule to strengthen energy conservation standards for dedicated purpose pool-pump motors. Our comments applaud the agency for appropriately applying the social cost of greenhouse gases to estimate the climate benefits of the proposed standards, even though the standards would be cost-benefit justified without considering any climate benefits. We also encourage DOE to expand upon its rationale for adopting a global damages valuation and for the range of discount rates it applies to climate effects.

The SEC has proposed a series of new disclosures for investment companies regarding their Environmental, Social, and Governance (ESG) activities. These disclosures would reduce "greenwashing" - a practice where companies misrepresent the sustainability of their investments in order to advertise to investors looking to invest in green funds - by providing investors with comparable and decision-useful information about fund practices. We submitted comments on the SEC's economic analysis of the Proposed Rule. We commend the Commission for complying with relevant case law and internal guidance on cost-benefit analysis and recommend steps that the SEC could take in the final rule to provide additional clarity and context regarding its findings.

The SEC has proposed a rule that would better align the names of investment companies with investor expectations, including for Environmental, Social, and Governance (ESG) investment funds, by requiring portfolio distribution requirements for funds whose name connotes a particular investment strategy. We submitted comments on the SEC's economic analysis of the Proposed Rule. We commend the Commission for complying with relevant case law and internal guidance on cost-benefit analysis and recommend steps that the SEC could take in the final rule to provide additional clarity and context regarding its findings.

Together with partner groups, we submitted joint comments to the Department of Energy (DOE) on its proposed rule to strengthen energy conservation standards for commercial water heating equipment. Our comments applaud the agency for appropriately applying the social cost of greenhouse gases to estimate the climate benefits of the proposed standards, even though the standards would be cost-benefit justified without considering any climate benefits. We also encourage DOE to expand upon its rationale for adopting a global damages valuation and for the range of discount rates it applies to climate effects.

Together with the Environmental Defense Fund and Professor Madison Condon of Boston University School of Law, we submitted three sets of comments to the Securities and Exchange Commission (SEC) in support of its Proposed Rule on the Enhancement and Standardization of Climate-Related Disclosures for Investors (Proposed Rule). The Proposed Rule would require publicly traded companies to disclose important information about the extent to which climate change is already affecting their financial performance, their approach to climate-related risk management, their climate-relevant governance structures, and their greenhouse gas emissions, which serve as a proxy for exposure to risk from policy- and market-driven shifts to a clean-energy economy.

In February 2022, the Environmental Protection Agency (EPA) proposed: (1) to revoke its May 2020 finding that it is not appropriate and necessary to regulate coal- and oil-fired electric utility steam generating units (EGUs) under Clean Air Act (CAA) Section 112 (2020 Action), and (2) to reaffirm the Agency's April 2016 finding that it remains appropriate and necessary to regulate hazardous air pollutant (HAP) emissions from EGUs after considering cost (2016 Supplemental Finding). Our comments on the Proposal explain why EPA should finalize both these actions as consistent with the Clean Air Act, case law, executive directives, principles of sound economic analysis, and past agency practice.

The Environmental Protection Agency (EPA) recently proposed airplane pollution standards that will have no effect on emissions and require no technological improvements. We filed comments urging EPA to evaluate a full suite of regulatory alternatives, including more stringent standards that would reduce emissions, and recommend that EPA conduct a distributional analysis to evaluate the impacts of the Proposed Rule and the relative distributional consequences for each regulatory alternative.

These comments were co-written with Clinical Associates Jenna Pearlson and Tanya Shahjanian.
