California Governor Gavin Newsom Signs Landmark Law Banning All Plastic Bags at Grocery Checkouts

California Governor Gavin Newsom signed landmark environmental legislation on Monday, formally enacting Senate Bill 1053 to institute an absolute statewide ban on all plastic carryout bags at grocery store and retail checkouts. The new statute, which takes effect on January 1, 2026, represents the nation's most aggressive legal strike against retail plastic waste.

The bill definitively closes a ten-year-old regulatory loophole created by California's pioneering 2014 single-use bag ban. Under that previous statute, thin single-use plastic sacks were prohibited, but supermarkets were permitted to sell thicker plastic film bags deemed 'reusable' and recyclable.

Closing the 2014 Loophole on Reusable Plastic Film

Environmental audits and state waste data subsequently revealed that almost none of the heavier plastic bags were ever recycled or reused. Instead, the tonnage of discarded plastic grocery bags per resident surged by nearly fifty percent over the following decade, littering ocean shorelines, choking urban storm drains, and degrading into toxic microplastics in aquatic ecosystems.

Under SB 1053, authored by State Senator Catherine Blakespear and Assemblymember Rebecca Bauer-Kahan, retail food establishments and supermarkets will be strictly restricted to offering carryout bags made from one hundred percent post-consumer recycled paper, or encouraging consumers to bring their own reusable washable fabric totes.

“Ten years ago California banned single-use plastic bags, but plastic film proliferated. Today we close that loophole once and for all to protect our coastline and marine life.” — Catherine Blakespear, California State Senator and Author of SB 1053

Retail Industry Adaptation and Environmental Impact

The bill received broad backing from conservation organizations, including the Surfrider Foundation, Heal the Bay, and the California Coastkeeper Alliance. Major grocery associations also supported the standardized measure, welcoming regulatory uniformity over a fragmented patchwork of municipal ordinances.

Environmental advocates predict that California's complete prohibition on plastic checkout bags will serve as an influential template for other states, setting a new benchmark for reducing petroleum-based single-use packaging across North America.
