In a 7-2 decision, the U.S. Supreme Court has delivered a crushing setback to California Governor Gavin Newsom’s ambitious environmental agenda, allowing energy producers to continue their lawsuit against the U.S. Environmental Protection Agency (EPA). The ruling, issued on July 31, 2025, challenges California’s stringent green energy mandates, which Newsom has championed as the nation’s most progressive climate policies. Justice Brett Kavanaugh, writing for the majority, noted that the case stems from California’s 2012 request for EPA approval of regulations limiting emissions, a move now contested by oil and gas companies.
The decision, joined by a liberal justice, underscores tensions between state environmental goals and federal oversight. Critics of Newsom’s policies argue the mandates burden businesses and raise energy costs, with California’s gas prices already 26% above the national average, per AAA data. Supporters, including Newsom, warn that weakening these rules threatens climate progress, citing California’s leadership in reducing emissions by 20% since 2005. The ruling doesn’t end the regulations but allows the lawsuit to proceed, potentially delaying or dismantling parts of Newsom’s agenda.
As a likely 2028 presidential contender, Newsom faces political fallout, with Republicans framing the decision as a victory for economic freedom. The case now returns to lower courts, where the fight over California’s environmental future will continue, raising questions about balancing green goals with economic realities.
