The U.S. Court of Appeals for the D.C. Circuit unanimously struck down the Trump administration’s toothless replacement of the Obama-era Clean Power Plan, which sought to reduce greenhouse gas emissions from the nation’s power sector. Richard Revesz and Dr. Burçin Ünel’s article on energy storage and greenhouse gas emissions was cited in the court’s opinion.

The Office of the Comptroller of the Currency (OCC) proposed a rule that would preclude banks from taking climate risks into account when making decisions regarding the provision of financial services. We submitted joint comments explaining how OCC fails to consider or justify serious costs imposed by the rule. Climate risks pose a significant threat to the economic and operational health of firms in the energy sector and to the stability of the financial system as a whole.

The Department of Health and Human Services (HHS) proposed Patient Protection and Affordable Care Act benefit and payment parameters for the 2022 coverage year that could cause significant health costs. We submitted comments on several elements of the proposed rule, including (1) its authorization of entirely privatized insurance marketplaces; (2) its promotion of the use of private enrollment websites by enrollment assisters; (3) its reduction of marketplace user fees; and (4) its continued reliance on a 2019 change to the formulas used to calculate premium-adjustment percentages and cost-sharing limits for consumers.

In April, the Environmental Protection Agency (EPA) and Army Corps of Engineers published the Navigable Waters Protection Rule, which considerably restricts the waters and wetlands that are federally protected under the Clean Water Act. We filed briefs in the Northern District of California and District of South Carolina focusing on the agencies’ economic analysis, which the agencies use to obscure the rule’s anticipated harms. We later filed in the Tenth Circuit Court of Appeals, the Northern District of New York, the District of Massachusetts, and the District of Maryland.

Our comments on the Revised Cross-State Air Pollution Rule Update for the 2008 Ozone NAAQS identify critical flaws in the proposal's design and regulatory impact analysis. The Environmental Protection Agency's (EPA) unreasonably low valuation of climate effects also contributes to its selection of an inefficient policy alternative. We submitted joint comments detailing how EPA's flawed analysis harms public health and the environment.

The Environmental Protection Agency (EPA) recently finalized revisions to New Source Performance Standards for methane and volatile organic compound (VOC) emissions from the oil and natural gas sector. We filed an amicus brief in the U.S. Court of Appeals for the D.C. Circuit, focusing on EPA's flawed legal and economic justifications for the rule. 

The Department of Health and Human Services (HHS) has proposed to retrospectively and prospectively establish an "expiration date" for each of its regulations. Under the proposed rule, regulations would be automatically rescinded unless HHS first completes a restrospective review of the regulation's effects on small entities pursuant to the Regulatory Flexibility Act. We submitted comments criticizing the proposal, which is neither lawful nor rational.

The Environmental Protection Agency and National Highway Traffic Safety Administration used several gimmicks and faulty assumptions to skew the analysis of the rollback rule, obscuring just how harmful it is to the American public. We published a series of reports examining several of the flaws.

The U.S. Court of Appeals for the Ninth Circuit ruled that the Department of Homeland Security’s “Public Charge” rule is both contrary to statute and arbitrary and capricious. Our amicus brief in the case played a key role in shaping the decision. The Ninth Circuit adopts our core arguments, emphasizing how Homeland Security fails to assess the rule's harms and draws conclusions that are contradicted by the record.
