What was the key legal outcome of the Supreme Court's Seven County Infrastructure Coalition v. Eagle County ruling regarding NEPA?

The U.S. Supreme Court unanimously ruled that federal agencies — such as the Surface Transportation Board — have final authority over the scope of environmental reviews required under NEPA, meaning they alone decide what upstream or downstream effects must be considered in environmental impact statements or assessments; the ruling does not eliminate NEPA but significantly limits its reach by affirming agency discretion over review boundaries.

Why do some critics — including both conservatives and progressive 'abundance' advocates — argue that NEPA has become an obstacle to important projects?

Critics argue NEPA functions as a 'brick wall' that repeatedly stops beneficial projects — such as clean energy infrastructure, affordable housing, and transit expansions — because its mandatory environmental review process causes delays and increases costs; Sarah Feinberg, former FRA administrator and NYC Transit interim president, stated that 'the two things that consistently can be counted on to stop really good projects... are NEPA and cost,' and that 'the cost is often worse because of NEPA.'
