The Trump Administration’s Pushback Against a Global Shipping Carbon Levy
The International Maritime Organization (IMO), the United Nations agency tasked with regulating global shipping, has proposed an international carbon pricing scheme on shipping. The maritime shipping sector has increasingly faced global scrutiny as the contributor of 3% of global greenhouse gas emissions, and IMO’s proposed mechanism would serve as the first global emissions pricing mechanism affecting the shipping sector.

Council on Environmental Quality Issues Long Awaited Guidance for Environmental Review Across Agencies
On September 29, 2025, the Council on Environmental Quality (CEQ) issued long-awaited guidance to formalize agencies’ individual efforts to implement the National Environmental Policy Act (NEPA). After rescinding the CEQ regulations that shaped NEPA for 40+ years and bearing witness to various agencies’ independent efforts to issue their own NEPA rules, CEQ issued new guidance to more systematically guide the agencies’ efforts. As CEQ notes, “NEPA implementation reform now has been called for, authorized, and directed by all three branches of government at the highest possible level: Congress, the President, and the Supreme Court.” The guidance reflects direction from each.
EPA Updates Clean Air Act Standards Applicable to Small Waste Incinerators
On June 30, 2025, the U.S. Environmental Protection Agency (EPA) finalized updates to its New Source Performance Standards (NSPS) and Emission Guidelines for Other Solid Waste Incineration (OSWI) units under the Clean Air Act (CAA). These units — combustion systems that incinerate solid waste from commercial or institutional sources not otherwise regulated under specific incinerator categories — include very small municipal waste combustors and institutional incinerators. The final rule includes applicability-related and definitional changes expanding the class of incinerators subject to NSPS, revises the OSWI subcategories and tightens emission limits for key pollutants. It also adopts changes to startup, shutdown, and malfunction (SSM), and expands testing, monitoring, reporting, and recordkeeping requirements that will affect both existing and new OSWI units.
Department of the Interior Accelerates Permitting for Oil and Gas, Adopts 28-Day Mandate
In response to the Trump administration’s push to increase U.S. energy output by declaring a national energy emergency, the Department of the Interior (the Interior) has released plans to aid the administration’s goals. These include the Interior’s Emergency Permitting Procedures intended to accelerate and streamline review and approval of certain energy projects, primarily oil and gas. Bypassing formal rulemaking, the Interior cites its authority during emergencies to implement “alternative processes” to comply with the National Environmental Policy Act (NEPA), the National Historic Preservation Act (NHPA), and the Endangered Species Act (ESA). The alternative processes are available to current and future applicants so long as they affirm in writing to the Interior that they qualify for and want to avail themselves of the expedited processes.
Fish and Wildlife Revives Incidental Take Saga Under the Migratory Bird Treaty Act
In latest saga surrounding the formidable Migratory Bird Treaty Act (MBTA or Act), the U.S. Fish and Wildlife Service on April 21, 2025, withdrew its 2021 advance notice of proposed rulemaking to potentially authorize the incidental taking or killing of migratory birds, consistent with its interpretation of the Act. The 2021 advance notice promised a new regulatory scheme possibly authorizing the incidental take of migratory birds — a practice that would have broken with pre-2017 MBTA interpretation but more practically implement the Act in response to various needs, such as infrastructure permitting and development.
The Future of Environmental Review of Federal Permitting Remains Unsteady as White House Seeks to Rescind NEPA Regulations
On February 19, 2025, the Council on Environmental Quality (CEQ) submitted a proposed Interim Final Rule rescinding its regulations implementing the National Environmental Policy Act (NEPA). The Rule will become effective 45 days after its publication in the Federal Register, marking the end of nearly 50 years of CEQ regulations serving as the foundation for federal environmental reviews. This Interim Rule comes right at the deadline set by President Trump’s Executive Order (EO) 14154—Unleashing American Energy—which rescinded CEQ’s authority to issue NEPA regulations and revoked President Carter’s EO 11991, which had originally directed CEQ to promulgate implementing regulations.
EPA Announces Enforcement Actions to Control Hydrofluorocarbon Imports
On March 2, 2023, the U.S. Environmental Protection Agency (EPA or Agency) announced several enforcement actions that support reducing the use of hydrofluorocarbons (HFCs). These actions include the following:

Companies With Environmental-Related Concerns Should Pay Attention to DOJ’s Voluntary Self-Disclosure Policy
On February 22, 2023, the U.S. Department of Justice (DOJ) announced the formalization of its voluntary self-disclosure policy for corporate criminal enforcement (VSD Policy) for all U.S. Attorney’s Offices (USAO). The VSD Policy details the circumstances under which a disclosure will qualify as a voluntary self-disclosure under the policy and, in turn, provides incentives to companies to make eligible self-disclosures. One such incentive — provided that the company makes an eligible self-disclosure, fully cooperates, and timely and appropriately remediates the criminal conduct — is that the USAO will not seek a guilty plea unless there are aggravating factors present. This is the first time DOJ has issued nationwide standards for voluntary self-disclosures for corporate criminal enforcement.
