Venue Matters: Supreme Court Clarifies Where Clean Air Act Cases Belong

On June 18, the U.S. Supreme Court issued two decisions that clarify a deceptively simple question under the Clean Air Act: Where should lawsuits challenging EPA actions be filed?

The rulings – EPA v. Calumet Shreveport Refining LLC and Oklahoma et al. v. EPA – do not change the substance of environmental law, but they do shape how and where that law gets litigated. And that matters.

At the heart of both cases is a venue provision in the Clean Air Act, which …

Decoding a Landmark Case: Environmental Laws and Legal Strategy in New Jersey’s PFAS Trial against DuPont

A high-stakes environmental trial is unfolding in New Jersey, where the state is taking on E.I. DuPont de Nemours and its related entities over widespread PFAS contamination at the former Chamber Works facility in Salem County. The outcome of this case — one of the most closely watched environmental proceedings in the country — could have a significant ripple effect on how other states pursue PFAS-related claims and how corporate defendants approach these increasingly high-profile cases.

In this case, New Jersey alleges that DuPont and …

Navigating Environmental Jurisdiction: DOJ’s Challenge to State Climate Superfund Laws

The U.S. Department of Justice filed lawsuits against New York and several other states, challenging their newly enacted state Superfund laws (Superfund lawsuits). The laws aim to address the environmental damages attributed to climate change by requiring fossil fuel companies to contribute to state-managed funds designated for climate adaptation and cleanup efforts. The lawsuits raise questions about state and federal authority to regulate environmental matters.

Climate Superfund laws at the state level are modeled after the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), …

Earth Day 2025: States Step Up for Biodiversity Amid Global Goals

As we reflect on environmental stewardship this week, the accelerating loss of biodiversity remains one of the most critical challenges facing our planet. Healthy ecosystems provide essential services – clean air and water, pollination, climate regulation, and more – underpinning human well-being and economic stability. While international efforts aim to address this crisis, action within the United States increasingly relies on state-level leadership and legal innovation.

Globally, the primary framework for conservation is the UN Convention on Biological Diversity (CBD). In 2022, parties to the …

New Jersey Proposal Transitions PFAS Criteria to Enforceable Remediation Standards

In March, the New Jersey Department of Environmental Protection (NJDEP) proposed to formally add GenX, PFNA, PFOA, PFOS — all PFAS compounds — and methanol to the list of regulated contaminants under various statutes.

This includes the Ground Water Quality Standards (GWQS), Remediation Standards, and Technical Requirements for Site Remediation.

The proposed amendments establish a specific ground water quality criterion for GenX, as well as soil and soil leachate remediation standards for PFNA, PFOA, PFOS, GenX, and methanol. Each of these contaminants were previously regulated …

Is Environmental Activism Litigation in Trouble?

In a landmark decision, a North Dakota jury has ordered Greenpeace to pay over $660 million in damages to Energy Transfer, the company behind the Dakota Access Pipeline (DAPL). This verdict stems from Greenpeace’s involvement in the 2016-2017 protests against the pipeline’s construction near the Standing Rock Indian Reservation. Energy Transfer accused Greenpeace of defamation, trespassing, nuisance, and civil conspiracy, alleging that the organization orchestrated violent protests and disseminated false information about the pipeline, leading to significant financial losses.

New Strategy is Embraced for Product Identification in Multidistrict PFAS Litigation

The Aqueous Film-Forming Foam (AFFF) MDL has taken a significant step forward with the introduction of a new case management program intended to streamline the complex process of product identification. The program’s structured approach is designed to enhance efficiency and accuracy in identifying the sources of contamination, thereby facilitating more effective legal proceedings.

The AFFF MDL is a multidistrict litigation that consolidates thousands of lawsuits across the United States concerning exposure to per- and polyfluoroalkyl substances (or PFAS). Due to its motility and unique chemical properties, …

California Withdraws EPA Waiver Request for Zero-Emission Advanced Clean Fleet Regulations

California’s Air Resources Board (CARB) on Jan. 13 sent a letter to withdraw its request to the Environmental Protection Agency pursuant to Sections 209(b) of the Clean Air Act (CAA) for a federal waiver that would require commercial truckers to switch to using zero-emissions vehicles in accordance with the CARB’s Advanced Clean Fleets regulation (ACF).

Had it been granted a waiver, CARB would have been allowed to put into effect the drayage and “high priority fleets” provisions of the ACF. CARB first requested this wavier …
