On June 20, 2025, the Supreme Court issued it opinion in Diamond Alternative Energy v. EPA, holding fuel producers had standing—and had specifically demonstrated redressability—to challenge California-specific regulations EPA approved under the Clean Air Act.  The Court’s opinion  reversing and remanding to the D.C. Circuit left the merits of the case for another day, but acknowledged that the regulations at issue may be rescinded shortly, mooting most, if not all, of the parties’ controversy. Read More »

In March 2024, the County of Bucks filed a controversial suit under state law against a number of large oil companies alleging the County was injured because of the companies’ deceptive conduct with respect to their impact on climate change. The Defendants filed various preliminary objections including lack of subject-matter jurisdiction, arguing that despite the County’s effort to focus the complaint on fraudulent practices, the case at bottom alleged harm from severe weather allegedly due to air emissions, which are governed exclusively by federal law. On May 16, 2025, the Bucks County Court of Common Pleas issued an opinion agreeing with the Defendants and dismissing the case entirely.  See Bucks County v. BP P.L.C., et al., No. 2024-01836 (Bucks Cty. Com. Pl. May 16, 2025). Read More »

On July 18, 2024, in Shirley v. Pennsylvania Legislative Reference Bureau, No. 85 MAP 2022, 2024 WL 3450536 (Pa. July 18, 2024), the Pennsylvania Supreme Court reversed the denial of three nonprofit organizations’ application to intervene in the litigation challenging the Pennsylvania Department of Environmental Protection (PADEP) regulation implementing Pennsylvania’s participation in the Regional Greenhouse Gas Initiative (the RGGI Regulation).  After rejecting several arguments regarding the appealability of the order denying intervention, the Court found that the nonprofits’ interest in defending the RGGI Regulation under the Pennsylvania Constitution’s Environmental Rights Amendment (ERA) was not adequately represented by the PADEP and therefore the lower court erred in denying intervention.  Because of this ruling, the three nonprofit organizations (Citizens for Pennsylvania’s Future, Clean Air Council, and the Sierra Club) (Nonprofits) are now able to pursue an appeal of the Commonwealth Court’s final order permanently enjoining the RGGI Regulation from going into effect.  Read More »

The Eleventh Circuit recently addressed the standing requirements for a procedural-rights claim, in this case one arising from an agency’s alleged failure to comply with the National Environmental Policy Act (“NEPA”).  In a split 2-1 decision in Center for a Sustainable Coast v. U.S. Army Corps of Engineers, the court held that standing to challenge an agency’s alleged violation of NEPA does not require a showing that a procedural do-over would necessarily redress a substantive injury. No. 22-11079, 2024 WL 1918733 (11^th Cir. May 2, 2024). Read More »

On September 14, 2023, in Conservation Law Foundation v. Academy Bus, a Massachusetts District Court held that the members of the Conservation Law Foundation (the “Foundation”) lacked standing to challenge the idling of buses under the Clean Air Act (“CAA”).  Conservation Law Found. v. Acad. Express, LLC., No. 20-10032-WGY, 2023 WL 5984517, at *1 (D. Mass. Sept. 14, 2023). Specifically, the court held that simply breathing in polluted air, without any concrete injury that is fairly traceable to the defendant, is not sufficient to prove an actual injury under the CAA.

On July 5, 2023, the United States Department of the Interior’s Bureau of Ocean Energy Management (BOEM) approved the largest offshore wind energy project to date—known as Ocean Wind 1—which will entail the construction of up to 98 wind turbines and up to 3 offshore substations off the coast of New Jersey over the next two years.  Ocean Wind 1, financed by the Danish company Orsted, is the third offshore wind energy project to gain approval by the Biden administration, following the Vineyard Wind project off the coast of Massachusetts and the South Fork Wind project off the coast of Rhode Island and New York, which are both currently under construction.

Over the last week, pre-enforcement challenges to two separate federal government actions have been dismissed for lack of standing.  In Commonwealth of Kentucky et al. v. EPA, et al., No 3:23-cv-00007-GFVT, 2023 WL 2733383 (E.D. Ky. March 31, 2023), the Honorable Gregory F. Van Tatenhove of the United States District Court for the Eastern District of Kentucky dismissed without prejudice claims brought by the Commonwealth of Kentucky (the “Commonwealth”) and private-sector plaintiffs challenging the United States Environmental Protection Agency’s (“EPA”) and Army Corps of Engineers’ rule redefining “waters of the United States” under the Clean Water Act.  Five days later, in The State of Louisiana, et al. v. Joseph R. Biden, Jr., et al., No. 22-30087, 2023 WL 2780821 (5th Cir. April 5, 2023), the Honorable Jacques L. Wiener, Jr. of the United States Court of Appeals for the Fifth Circuit dismissed states’ challenges to President Biden’s social cost of greenhouse gases established pursuant to Executive Order No. 13990 (the “Executive Order”).  Both cases demonstrate the importance of alleging sufficient harm to confer federal court jurisdiction.

That federal agencies enjoy numerous advantages in defending against legal challenges to their administrative decision-making is a fact of administrative law.  But these advantages extend beyond the favorable standards of review that typically apply to their decisions.  An agency can, for example, sometimes short circuit what might be a meritorious appeal by seeking a “voluntary remand” from the Court, thereby potentially affording itself more control over any reconsideration while avoiding creating unfavorable precedent.  As a reminder of this, the Sixth Circuit recently held that EPA was entitled to reconsider one of its Clean Air Act (CAA) rulemakings, namely its decision to remove the air nuisance rule (ANR), a broad standard that generally prohibited nuisance emissions that endangered the “health, safety, or welfare of the public,” from Ohio’s State Implementation Plan (SIP), without the Court vacating EPA’s underlying decision.  Sierra Club et al. v. EPA, No. 21-3057, 2023 WL 1873168, at * 1 (6th Cir. Feb. 10, 2023).    Read More »

In Curtis v. 7-Eleven, No. 21-cv-6079, 2022 WL 4182384, at * 1 (N.D. Ill. Sept. 13, 2022), the Honorable Steven C. Seeger of the United States District Court for the Northern District of Illinois delivered an eminently readable and entertaining decision, granting in part and dismissing in part 7-Eleven’s motion to dismiss a number of “greenwashing” claims brought against it by putative class representative, Devon Curtis.  Greenwashing is defined as “the act or practice of making a product, policy, activity, etc. appear to be more environmentally friendly or less environmentally damaging than it really is.” In her complaint, Curtis alleges that she purchased foam plates, foam cups, party cups, and freezer bags from 7-Eleven.  Even though these products were labeled “recyclable”, Curtis alleges that they never really were, either because very few recycling facilities accept these products or because some of the products lacked markings, known as RIC numbers, which recycling facilities use to sort products by plastic type.   Read More »

Before neighboring property owners can intervene to challenge a consent decree in a remediation action, they must establish Article III standing. On August 5, 2022, The United States Court of Appeals for the Eighth Circuit affirmed the ruling of the United States District Court for the District of Minnesota and held that neighboring property owners of a chemical plant undergoing environmental remediation lacked constitutional standing to intervene to oppose an amended consent decree and remedial action plan. United States v. Reilly Tar & Chem. Corp., Slip Op. No. 20-2786 (8^th Cir. Aug. 5, 2022). The court reasoned that the entry of the amended consent decree was not a causal link of the proposed intervenors’ harm because it did not require the chemical plant to clean-up chlorinated volatile organic compounds (CVOCs) and perchloroethylene (PCE) and therefore did not alter the chemical plant’s preexisting duties regarding PCE. Id.
