More than 500 cities and 12 U.S. states have now banned single-use plastic bags — and a new report confirms the bans are working. Drawing on industry and government data, researchers estimate that plastic bag bans can eliminate nearly 300 single-use plastic bags per person per year, keeping billions of bags out of landfills, waterways, and wildlife habitats.
At a glance
- Plastic bag bans: More than 500 U.S. cities and 12 states have now enacted restrictions on single-use plastic bags, with Georgia and Massachusetts potentially joining soon.
- Single-use plastic reduction: New Jersey’s 2022 C.E. statewide ban alone has eliminated more than 5.5 billion plastic bags annually — the largest impact of any policy examined in the report.
- Microplastic exposure: Plastic bags shed tiny fragments linked to metabolic disorder, neurotoxicity, and reproductive damage in humans, adding urgency to reduction efforts beyond litter concerns alone.
What the report found
The report was co-published by three nonprofits: Environment America, the U.S. Public Interest Research Group Education Fund, and Frontier Group. Researchers focused on five representative policies — in New Jersey, Vermont, Philadelphia, Portland (Oregon), and Santa Barbara (California) — and used data from municipal agencies, academic researchers, and plastics and grocery industry groups.
Outside New Jersey, bans in the other four jurisdictions eliminated between roughly 45 million and 200 million plastic bags per year, depending on population size. Together, the results paint a clear picture.
“The bottom line is that plastic bag bans work,” said Faye Park, president of the U.S. PIRG Education Fund. “People realize quickly it’s easy to live without plastic bags and get used to bringing a bag from home or skipping a bag when they can.”
Why plastic bags matter so much
The case against plastic bags runs from production to disposal. They are made from oil and gas. They cannot be recycled. The average plastic bag is used for about 12 minutes, then either incinerated or sent to a landfill, where it can persist for hundreds of years.
As litter, plastic bags and plastic films cause more deaths of sea turtles, whales, dolphins, and porpoises than any other type of plastic. And the harm does not stop at wildlife.
“It feels like there’s a study a week showing that plastics are not just littering and polluting the environment, but digging into our bloodstream,” said Janet Domenitz, executive director of MassPIRG. Microplastics — tiny fragments shed by plastic bags — may be linked to metabolic disorder, neurotoxicity, and reproductive damage in humans. They also release greenhouse gases that contribute to climate change.
The nuances worth knowing
Not everyone is convinced bag bans are the right tool. Some critics argue the policies are symbolic while larger environmental problems go unaddressed. Others contend they burden businesses or limit consumer choice. As of 2021 C.E., 18 states had passed preemption laws preventing local governments from enacting their own bans.
One widely circulated 2018 C.E. study claimed a cotton bag would need to be reused 20,000 times to offset the environmental cost of making it. Other research has shown that paper bags require more energy and water to produce than plastic ones — raising questions about whether bans simply shift consumption rather than reduce it.
Experts who support bans push back on those comparisons, arguing they fail to account for the full life-cycle impact of plastic once it is discarded or littered. Celeste Meiffren-Swango, co-author of the report and Beyond Plastic campaign director at Environment America Research and Policy Center, told Grist: “The intent of these laws isn’t to shift from a single-use bag to another single-use bag.” She recommended that bag bans include a 10-cent charge for paper bags to encourage people to bring reusable alternatives.
The report also flagged a loophole in some jurisdictions that allowed retailers to replace thin single-use bags with thicker ones marketed as reusable — even though consumers rarely reuse them. In California, this loophole contributed to a net increase in the weight of plastic bags used per person between 2004 C.E. and 2021 C.E. The researchers urged policymakers to close such gaps by banning plastic bags of any thickness.
A policy that keeps gaining ground
The 12 states with active bans — California, Colorado, Connecticut, Delaware, Hawai’i, Maine, New Jersey, New York, Oregon, Rhode Island, Vermont, and Washington — represent a substantial share of the U.S. population. Pending legislation in Georgia and Massachusetts could extend the map further.
The broader trend is clear: once people stop using disposable bags, they adapt quickly and don’t go back. Billions of bags that were never made, never used, and never discarded represent a quiet but meaningful shift in how everyday consumption can change with the right policy nudge.
