California bill would ban all plastic shopping bags at grocery stores

Democratic state Sen. Catherine Blakespear said people are not reusing or recycling those bags. She points to a state study that found the amount of plastic shopping bags trashed per person grew from 8 pounds per year in 2004 to 11 pounds per year in 2021.

"It shows that the plastic bag ban that we passed in this state in 2014 did not reduce the overall use of plastic. It actually resulted in a substantial increase in plastic," Blakespear, a Democrat from Encinitas, said Thursday. "We are literally choking our planet with plastic waste."

Twelve states, including California, already have some type of statewide plastic bag ban in place, according to the environmental advocacy group Environment America Research & Policy Center. Hundreds of cities across 28 states also have their own plastic bag bans in place.

While California's bag ban would apply statewide, it would only end up impacting about half the state's population, according to Mark Murray, lead advocate for the environmental advocacy group Californians Against Waste. That's because most of the state's major cities already ban these types of thicker plastic bags. But a state law passed in 2014 and approved by voters in a 2016 referendum bans cities from passing new laws restricting plastic bag use.

If the Legislature passes this bill, it would be up to Democratic Gov. Gavin Newsom to decide whether to sign it into law. As San Francisco's mayor in 2007, Newsom signed the nation's first plastic bag ban.
