End of an (Endangerment) Era

February 23, 2026 — Sukhmani K. Singh, Christopher P. Colyer & Sean M. Sherlock - Snell & Wilmer
On February 12, 2026, the U.S. Environmental Protection Agency (EPA) announced the repeal of the 2009 Greenhouse Gas (GHG) Endangerment Finding and the elimination of all federal GHG emission standards for motor vehicles and engines.1 The EPA characterized the action as the “single largest deregulatory action in U.S. history.”2 This development marks a fundamental shift in federal climate policy under the Clean Air Act (CAA) and is expected to trigger immediate and extensive litigation. In Massachusetts v. EPA, the U.S. Supreme Court held that GHGs qualify as “air pollutants” under the CAA and that the EPA must determine whether emissions from new motor vehicles cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare under CAA Section 202(a).3 Following this decision, on December 7, 2009, the EPA issued two findings. First, the EPA classified six different GHGs as threatening public health and welfare. Second, the EPA determined that emissions from new motor vehicles contribute to that endangerment.4 Although the findings themselves imposed no direct regulatory requirements, they served as the legal predicate for GHG emission standards for light-duty and heavy-duty vehicles, and later for other CAA programs affecting statutory sources. In 2012, the U.S. Circuit Court of Appeals for the District of Columbia upheld the Endangerment Finding and related regulations.5 Reprinted courtesy of Sukhmani K.

California’s Retention Reform on Private Construction Projects

February 17, 2026 — Michael McKeeman - The Construction Seyt
Retention has long been a contentious issue in California construction. Traditionally, owners withheld retention of 10% from each progress payment until completion, arguing it was necessary to ensure performance, quality and timely delivery. Contractors and subcontractors, however, often struggled with cash flow, payroll, and material costs while waiting months—sometimes even years—for withheld retention. Recognizing the financial challenges contractors and subcontractors face, the California legislature passed Senate Bill 61 (“SB 61”), now codified under California Civil Code Section 8811 and effective January 1, 2026, limiting retention to 5% on private works of improvement, aligning with the public works standard in place since 2012. The law’s intent is clear—ease financial strain on contractors and subcontractors while still providing owners with security (albeit reduced) with respect to project completion.

Are Robotic Coworkers Soon a Reality in Construction?

March 24, 2026 — Aarni Heiskanen - AEC Business
General-purpose humanoid robots are in the headlines, but is the hype justified? What’s the point of having a robot home assistant when it still needs a “guy behind the curtain” to control it remotely? Despite the challenges, robots, even those that look like humans, are seriously considered as future coworkers in business environments. According to the McKinsey report ‘Will embodied AI create robotic coworkers?‘ the idea that AI-powered robots will become general-purpose coworkers is grounded in real technological progress, but not an overnight reality.

Nevada’s Mandatory Nonbinding Arbitration Law for Civil Cases is Going Through Changes

May 14, 2026 — Brandon Wright & Manuel Gurule - Lewis Brisbois
Nevada currently operates an expedited litigation program designed to resolve civil disputes with a value up to $50,000 without incurring the “usual” expense of litigating these disputes. Over time, however, the number of civil cases that have been “exempted” from this program based on the claimed damages exceeding $50,000 has grown dramatically. In response, the Nevada Legislature recently enacted a number of rule changes designed to streamline Nevada’s arbitration process and include more cases. Among these changes are increasing the arbitration “cap” from $50,000 to $100,000. By way of background, the Nevada’s Court Annexed Arbitration program is a mandatory, non-binding program for civil cases in judicial districts that have county populations of 100,000 or more [1]. Nevada’s Court Annexed Arbitration was born out of NRS 38.250, which was enacted in 1991 and went into effect in the summer of 1992. The newly enacted NRS 38.250 was regarded as a way to address the problem of increased court caseloads while promoting judicial economy and efficiency in civil cases having a probable jury award of less than $25,000 [2]. Initially, cases that were automatically exempt from the program included class actions, medical malpractice disputes, divorce proceedings, and other domestic relations matters [3].

World's Longest Immersed Tunnel Passes Milestone, But Faces Delays

But Danish state-owned project owner Femern A/S says the plan is now running at least two years behind schedule and the tunnel’s road and rail portions will open in two separate stages.

U.S. Supreme Court Decision Alters Course of $745M Louisiana Coastal Damage Judgment

June 15, 2026 — Jennifer Kretschmann & Jennifer E. Michel - Lewis Brisbois
The U.S. Supreme Court has issued a unanimous decision allowing oil and gas companies to move Louisiana coastal erosion lawsuits from state court to federal court under the federal officer removal statute. While the ruling is procedural, it carries significant implications for environmental- and energy-related risks. The case, Chevron U.S.A. Inc. v. Plaquemines Parish, Louisiana, Slip Op. 24-813 (April 17, 2026), addressed a threshold jurisdictional question but has broader significance for environmental and climate related litigation. State courts are often viewed as more favorable forums for plaintiffs asserting environmental damage claims, particularly those brought by governmental entities. The opinion issued on April 17, 2026 is the latest development in long-running Louisiana coastal litigation that began more than a decade ago. Starting in 2013, Louisiana parishes filed 42 lawsuits against oil and gas companies alleging environmental damage related to historic oil field operations. The parishes alleged that oil and gas companies violated state coastal management laws by failing to properly restore impacted areas. Chevron sought to remove the cases from state court under 28 U.S.C. § 1442(a)(1), known as federal officer removal, which provides federal jurisdiction over “any person acting under [an] officer” of the United States "for or relating to any act under color of such office." The Fifth Circuit rejected the argument and remanded the case, and others like it, to state court. Trial began in March 2025 in Point à la Hache, Louisiana. On April 4, 2025, the jury awarded a total of $745 million to compensate for land loss, contamination and abandoned equipment. On June 16, 2025, the U.S. Supreme Court agreed to review the question of whether a federal contractor can remove to federal court when sued for oil-production activities undertaken to fulfill a federal oil-refinement contract.
