California Governor Gavin Newsom has vetoed AB 2253, a bill designed to crack down on misleading recycled-content claims, dealing a setback to state-level anti-greenwashing enforcement in the largest U.S. state market for recycled materials.

The governor's stated reason was economic. In his veto message, Newsom said he did not want to "unduly burden manufacturers and suppliers already facing economic headwinds caused by federal tariff and trade policy actions."

The veto closes — for this session — a legislative path that would have tightened the rules governing how companies advertise recycled content in products sold in California. Bills of this type typically assign verification duties to a state agency and create exposure to penalties for unsupported claims, shifting a portion of the enforcement burden onto manufacturers and their suppliers.

That compliance burden is precisely what the governor declined to impose. Newsom's framing places AB 2257's fate in the context of federal trade policy: tariffs raising input costs for manufacturers, and a state legislature wary of layering new disclosure obligations onto that cost pressure. The veto signals that, in the current environment, California's executive branch will weigh circularity and truth-in-labeling measures against perceived regulatory cost.

For producers of recycled commodities — resin, fiber, glass and metal suppliers that depend on demand pulled through by recycled-content commitments — the practical question is what enforces those commitments in the absence of a statute. Voluntary pledges remain, by definition, commitments without a state enforcement mechanism. Federal action on deceptive environmental claims exists, but California's bill represented a state-level tool that is now off the table.

The legislature can override a veto, though that outcome is rare. The more likely route for supporters is reintroduction in a future session, when the tariff-driven cost argument may carry less weight. Expect recycled-content verification to return to the California agenda.
