Trump Administration Challenges California Gas Restrictions in Escalation of Clean Energy Dispute

The Trump administration has filed a lawsuit against two California cities—Morgan Hill and Petaluma—seeking to overturn local ordinances that restrict natural gas infrastructure and appliances in new buildings. The case, filed in U.S. District Court for the Northern District of California, marks the latest federal pushback against state and local policies aimed at reducing fossil fuel use to address climate change.

Justice Department attorneys argue that the cities’ ordinances, adopted since 2019, violate a 1975 federal law that bars states and municipalities from regulating the “energy use” of products already subject to federal standards. The complaint claims that the gas restrictions impose “crushing costs” on residents and are unlawful under federal preemption rules.

The lawsuit comes amid long-standing Republican opposition to Democratic-led efforts to phase out gas-powered appliances. California, widely regarded as a leader in climate policy, has seen dozens of municipalities adopt similar measures over the past several years.

In 2023, a federal appeals court ruled that Berkeley could not enforce its own natural gas ban, setting a precedent the administration now seeks to extend. Officials in Petaluma and Morgan Hill have not yet substantively responded to the lawsuit.
