Supreme Court: Environmental Reviews Limited
Supreme Court Limits Environmental Impact Statements, Backing Developers
Updated May 29, 2025
The Supreme Court has narrowed the scope of environmental impact statements, a move seen as a victory for developers. The justices, in a unanimous decision, ruled that these statements have been used too broadly, causing unneeded delays and hindering new projects.
Justice Brett M. Kavanaugh, writing for the court, stated that the National Environmental Policy Act (NEPA) of 1970 had evolved into a tool that granted judges and environmentalists excessive power to obstruct growth. He argued that this overreach has led to fewer projects being completed, increased costs, and ultimately, fewer jobs.
The ruling could have notable implications, notably in states like California and throughout the West, where the 9th Circuit Court of Appeals has historically adopted a broad interpretation of environmental protection and the required scope of impact statements.
The case revolved around a proposed 88-mile railroad in northeastern Utah intended to transport crude oil for refining along the Gulf Coast. While the U.S. Surface Transportation Board produced extensive analysis on the project’s potential impact, the D.C. Circuit court of Appeals blocked the proposal, citing potential increases in oil drilling and pollution. The Supreme Court, though, sided with the developers, arguing that the board was not obligated to evaluate the environmental impacts of separate upstream and downstream projects.
Justices Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson concurred with the decision but did not endorse Kavanaugh’s opinion. Justice neil M. Gorsuch recused himself from the case.
“A 1970 legislative acorn has grown over the years into a judicial oak that has hindered infrastructure development under the guise of just a little more process. A course correction of sorts is appropriate,” said Justice Brett M.Kavanaugh.
What’s next
This ruling is expected to streamline the approval process for infrastructure projects nationwide, potentially leading to faster development and reduced costs. Though, environmental groups may seek choice legal avenues to challenge projects they believe pose significant environmental risks.
