In January, the Council on Environmental Quality published interim guidance providing best practices to federal agencies on the consideration of climate change in environmental reviews conducted under the National Environmental Policy Act. The guidance provides helpful direction to agencies on assessing how proposed actions and their alternatives (1) will contribute to climate change through their greenhouse gas emissions; and (2) will potentially be affected or have their environmental consequences exacerbated by climate change impacts. Our comment commends CEQ on its thorough guidance and provides recommendations to strengthen both areas. 

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.

We submitted comment letters to the Department of Energy (DOE) on its proposed rules to strengthen energy conservation standards for general service lamps and distribution transformers. Our comments applaud the agency for appropriately applying the social cost of greenhouse gases to estimate the climate benefits of the proposed standards. We also suggest that DOE apply additional analysis to each rule using draft updated climate-damage valuations that the Environmental Protection Agency released in November 2022.

In December 2021, the Environmental Protection Agency finalized a regulation to strengthen its greenhouse gas emission standards for light-duty vehicles. Although regulated automakers support EPA’s approach, a group of states and oil-and-gas companies have challenged the standards in the U.S. Court of Appeals for the D.C. Circuit, claiming that the standards misapply economic principles and violate the major questions doctrine. In our amicus brief, we explain that EPA’s regulation is consistent with sound economics and established practice.

We submitted comments to the Department of Energy (DOE) on its proposed rule to strengthen energy conservation standards for new and renovated federal buildings. Our comments offer support for the agency's choice to apply the social cost of greenhouse gases to estimate the climate effects of the proposed standards. We also suggest that DOE apply additional analysis using draft updated climate-damage valuations that the Environmental Protection Agency recently released.

This month, EPA restored the legal foundation for regulating emissions of mercury and other hazardous air pollutants (HAPs) from coal- and oil-fired power plants under section 112 of the Clean Air Act. Policy Integrity has long recommended that EPA adopt such an approach that considers unquantified and ancillary effects, as is consistent with the best economic practices and the law, including through our comments on the 2022 proposed rule and an amicus brief opposing the 2020 finding. 

We submitted comments to the Federal Acquisition Regulatory Council (FAR Council) on ways to strengthen its proposed rule that would require certain categories of federal contractors to disclose their greenhouse gas emissions and climate-related financial risk, and in some cases set science-based targets to reduce their greenhouse gas emissions.

Together with a coalition of environmental groups, we submitted comments to EPA on its draft update to the social cost of greenhouse gas estimates of climate damage. We commended the agency's extraordinary advances and recommended ways to further improve the accuracy of the metrics.
