Recent Projects

In March 2024, the Department of Transportation (DOT) proposed a multifaceted regulation that would facilitate greater access to air transportation for passengers with disabilities, particularly those who depend on wheelchairs and other assistive devices. Policy Integrity submitted comments to the agency arguing that, while DOT persuasively shows that the Proposed Rule carries many important benefits, the agency should improve upon its proposal and the accompanying benefit-cost analysis in several ways

On April 24, 2024, DOT issued a final rule on airline ticket refunds which, among other things, will require airlines to offer refunds when a passenger’s itinerary is significantly changed or delayed, and will require that passengers be given a ticket voucher if a serious communicative disease prevents them from flying. We submitted comments to DOT in November 2022 explaining that, in our view, DOT’s benefit-cost analysis was underestimating the benefits of these policies. DOT’s finalized analysis discusses our comments extensively, and implements many of our suggestions.

In August, the National Highway Traffic Safety Administration (NHTSA) proposed to strengthen vehicle fuel-economy standards. Since then, the Environmental Protection Agency has finalized its update to the social cost of greenhouse gases and the Office of Management and Budget has finalized its revisions to Circular A-4. In light of these updates, we submitted a supplemental comment letter reasserting our call for NHTSA to assess regulatory impacts using the best available economics.

In August 2023, the National Highway Traffic Safety Administration (NHTSA) proposed a regulation to strengthen corporate average fuel economy standards for passenger cars, light trucks, and heavy-duty pickup trucks and vans. In a comment letter, we explain that while the Proposed Rule and its accompanying regulatory impact analysis offer useful starting points, NHTSA should take further steps to ensure the complete presentation of regulatory benefits and costs and should select a regulatory option that best promotes social welfare, consistent with the agency’s legal obligations. We also submitted joint comments with a coalition of other environmental groups on NHTSA’s use of the social cost of greenhouses gases in the Proposed Rule.

In May 2022, the National Highway Traffic Safety Administration (NHTSA) finalized a rule to increase its corporate average fuel economy (CAFE) standards for passenger cars and light trucks for model years 2024–2026. A group of fuel and petrochemical manufacturers and states challenged the standards in the U.S. Court of Appeals for the D.C. Circuit, arguing primarily that the Energy Policy and Conservation Act bars NHTSA from including electric vehicles in the analytical baseline for the new standards. Our amicus brief explains that longstanding administrative guidance and case law direct agencies to develop baselines that reflect their best assessment of the real world absent any new agency action. In the context of this rulemaking, that guidance and case law required NHTSA to project how many and what kinds of vehicles—including electric (and plug-in hybrid electric) vehicles—would be built and sold if it did not issue new CAFE standards, which is what NHTSA did here. Our amicus brief also explains that NHTSA has consistently prepared baselines for prior CAFE standards in this manner.

DOT recently proposed a rule that would require airlines to issue refunds or non-expiring vouchers to consumers whose flights are significantly delayed or canceled or who decide not to travel for certain health reasons. Policy Integrity submitted comments in support of the proposal, and made recommendations to clarify and strengthen the final rule.

We submitted comments on NHTSA's proposed car standards, recommending ways that the agency could improve its modeling and address inconsistences between its and EPA's analyses. We also submitted joint comments on NHTSA's use of the social cost of carbon, recommending that the agency expand its justification of its discount rates and inclusion of global damages in the SCC.

The National Highway Traffic Safety Administration ("NHTSA") sets corporate average fuel economy ("CAFE") standards for light-duty vehicles, and penalizes automobile manufacturers who fail to meet applicable standards. In January 2021, NHTSA issued an Interim Final Rule repealing the inflation-adjusted penalty increase for Model Years 2019-2021, which we commented was untimely and disregarded critical environmental harms. 

In August 2021, NHTSA proposed to rescind the Interim Final Rule. We filed comments supporting the proposal for complying with inflation-adjustment obligations, driving fuel savings, and reducing pollution.

The National Highway Traffic Safety Administration's interim final rule delays the application of its 2016 inflation adjustment of the penalty for violating the corpoate average fuel-economy (CAFE) standards. We submitted comments explaining that the rule is untimely under the Inflation Adjustment Act, whose deadlines to amend the intial catch-up inflation adjustment expired years ago.

We filed an amicus brief explaining how NHTSA and EPA's decision to finalize a rule that, even under their own analysis, will be net-costly to society, is arbitrary and capricious.
