California Attorney General Issues Enforcement Advisory Reminding Businesses Not to Sell Polystyrene Foam in California
Nearly one year after California’s ban on polystyrene foam took effect under Senate Bill 54, illegal products are still widely available across the state. On December 2, 2025, California Attorney General Rob Bonta issued an enforcement advisory to producers of polystyrene foam food service ware, warning them that continued sales, distribution, or importation of these products in or into California violates state law.
California’s Polystyrene Foam Ban Is Not Being Enforced, Say Environmental Advocates
More than 90 organizations — including Beyond Plastics, Plastic Pollution Coalition, Californians Against Waste, Surfrider, and California Nurses for Environmental Health and Justice — have sent a letter to California Governor Gavin Newsom calling for him to enforce the statewide ban on polystyrene foam food service products that went into effect on January 1, 2025. Despite the ban being in place for five months, these items remain widely available in stores and online.
