EPA finalized a rule updating the MATS (mercury and air toxics) limits for certain fossil-fuel-fired power plants in May 2024. These limits were issued pursuant to Section 112(d)(6) of the Clean Air Act, which gives EPA authority to update regulations based on improvements in processes and control technologies. Policy Integrity submitted an amicus brief in merits litigation before the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) in which we responded to Petitioners’ false assertions that the Rule has no public health benefits and EPA improperly considered the costs and benefits of the Rule.

In May 2023, the NYPSC initiated a process regarding the CLCPA's Zero Emissions Target, and the early phases of that process have focused on interpreting the 2040 goal, which is fraught with ambiguity. To date, this process has included two requests for public comment as well as a Department of Public Service technical conference. Policy Integrity has made comments throughout, and hosted a conference on state-level pathways to zero-emissions electric grids, focusing in significant part on this statutory requirement. On November 4, DPS Staff filed a document proposing definitions of key terms that aligns with Policy Integrity's recommendations and approach in key respects.

The National Environmental Policy Act requires agencies to take a hard look at the environmental impacts of their decisions, prior to acting. In this case, the Surface Transportation Board, after conducting an environmental review, permitted a proposed railway that would transport oil in Utah’s Uinta Basin. The D.C. Circuit found that the Board’s environmental analysis failed to properly consider the indirect effects of the railway, including increased drilling and pollution impacts in the Gulf Coast, due to an influx of crude oil and increased refinery operations. The Supreme Court granted certiorari in June 2024 on the question “whether the National Environmental Policy Act requires an agency to study environmental impacts beyond the proximate effects of the action over which the agency has regulatory authority.” We argue the Court should affirm the D.C. Circuit’s ruling and interpret NEPA–in line with longstanding precedent–to require agencies to consider reasonably foreseeable effects. 

EPA finalized greenhouse gas emission limits for existing coal-fired and new natural gas-fired power plants in May 2024. These limits were issued under authority from Section 111 of the Clean Air Act. Policy Integrity submitted an amicus brief in merits litigation before the U.S. Court of Appeals for the D.C. Circuit, addressing the relationship between regulation of new and existing sources under Section 111 of the Clean Air Act and the applicability of this Court’s past decisions reviewing EPA’s discretion on technical findings under Section 111.

The Institute for Policy Integrity submitted comments in the New York Public Service Commission’s Proceeding on Motion of the Commission in Regard to Gas Planning Procedures, responding to a notice posing various questions about non-pipeline alternatives (NPAs). Our comments focused on how NPAs can be compared fairly to conventional infrastructure alternatives.

In August 2024, the U.S. Army Corps of Engineers released a Draft Integrated Material Management Plan and Environmental Impact Statement as part of its Lower Columbia River Channel Maintenance Plan. In the EIS the Corps cited values for the social cost of greenhouse gases (SC-GHG) from the calculator on Policy Integrity’s Cost of Carbon Website. The Corps also citied our Cost of Carbon website when describing the SC-GHG in the Draft EIS.

In response to congressional interest in marine carbon dioxide removal (mCDR) the Congressional Research Service prepared a brief report on the subject. In the document, CRS cited our recent report on expert consensus about carbon dioxide removal to support that claim that “[some stakeholders] may invoke a moral hazard argument against CDR because they prefer policies and actions to reduce GHG emissions prioritized over those aimed at removing emitted GHG from the atmosphere.”

In March 2024, the Securities and Exchange Commission (SEC) finalized its rules on The Enhancement and Standardization of Climate-Related Disclosures for Investors (Rules). The Rules will require public companies in the United States to make certain climate-related disclosures in their registration statements and annual reports, giving investors critical information to better balance risk in their portfolios. Immediately following the Rules’ release, industry actors and a coalition of states filed lawsuits seeking to vacate the Rules. We filed an amicus brief in the Eighth Circuit, supporting these important Rules. Our brief argues that the petitioners’ economic arguments about the Rules’ costs and benefits suffer from fundamental flaws.

On July 29, 2024, the Workshop Facilitator for the Illinois Commerce Commission finalized its Future of Gas Phase 1 Workshops Facilitator Report to the Commission. The final report incorporated several recommendations that Policy Integrity made in comments responding to presentations and draft documents during the course of Phase 1.
