Gov. Gavin Newsom (D-CA) signed a law banning plastic bags from being sold at grocery stores, building on the state’s prior regulations of plastic bags.

Newsom signed a bill Sunday, alongside a slew of other pieces of legislation, that bans all forms of plastic bags available at checkout in state stores after a 2016 voter-passed ban on plastic bags still allowed consumers to buy a thick plastic bag for $0.10 each. The new legislation will take effect on Jan. 1, 2026, giving Californians more than a year to prepare for the change.
