Boulder, Colorado, passed stricter regulations against plastic bags at the beginning of 2024, banning them from all retail stores. The tougher rule builds on a 2013 local law that banned plastic bags from grocery stores and began charging shoppers 10 cents for every paper bag they required at checkout. The new law, part of the state’s Plastic Pollution Reduction Act, also prohibits restaurants and retail food establishments from using Styrofoam takeout containers.
The Conversation interviewed Eleanor Putnam-Farr, an assistant professor of marketing at Rice University and co-author of “Forgot Your Bottle or Bag Again? How Well-Placed Reminder Cues Can Help Consumers Build Sustainable Habits,” about the challenges of changing people’s behavior – even when their intentions are good.
How popular are plastic bag bans and taxes?
Laws like Boulder’s are popular. Twelve states, plus Puerto Rico, and more than 300 municipalities, including Philadelphia, have banned plastic bag use by consumers. Charging a fee for bags is less common, but rules like this are in effect in Washington, D.C.; Honolulu, Hawaii; Santa Fe, New Mexico; and other U.S. cities.
And these types of regulations aren’t limited to the U.S. Many other countries are also cracking down on plastic bag use, including China, Namibia and Portugal.
Cities and towns have tried a lot of strategies, from educating consumers to banning the use of bags or just nudging them to do the right thing by imposing small fees. Nudges leave the choice up to the consumer and are often more palatable than outright bans.
Do bans and taxes divert waste from landfills?
Many cities have reported decreases in plastic bag use after imposing plastic bag bans and fees, but the effects may be small.
In a study on the efficacy of a bag fee implemented in Toronto, researchers found a 3.4% increase in the use of reusable bags, mostly among higher-income customers.
But even a small reduction is progress, right?
Maybe. Research on parents who were assessed fees when they picked up their children late at 10 different day care centers found that small charges actually led to a big increase in tardy parents – who apparently felt they were paying for the right to be late.
Boulder may be fighting the same sort of complacency. Disposable bag fees collected from 2013 through 2022 fluctuated slightly year to year, but increased more often than not – suggesting that people are buying more bags, not fewer. Earning 6 cents for every bag sold – the stores keep the rest – Boulder brought in US$243,507 in tax revenue in 2021 and $248,518 in 2022.
Why don’t more consumers use reusable bags?
Consumers stick to plastic bags for many reasons, including convenience. Research on farmers market shoppers in Ohio suggests accidentally leaving reusable bags in their cars or at home is an obstacle, and some consumers prefer plastic bags because they reuse them for trash and pet waste. But researchers from Chile, which enacted a complete ban on plastic bags in 2019, found that people there at first weren’t committed to reusable bags. Consumers in Chile felt pressured to change their behavior, and guilty when they didn’t comply. They also felt like 100% of the burden of sustainability was forced on them, all of which undermined the goal of the ban.
What does work to encourage consumers to use reusable bags?
The most important thing is to understand that most people don’t set out to use more plastic. So the best solutions help consumers achieve their goals and make access to reusable bags easier. The key is to determine the biggest impediment to shoppers bringing reusable bags.
In our research about reusable bottles, my colleagues at the Yale Center for Customer Insights and at Google knew that most employees of the office site had reusable bottles but forgot to bring them to the water stations to refill them. Instead of banning plastic cups or disposable bottles, we created reminders and placed them near the workers’ desks. These reminders helped people behave the way they wanted to behave and had the added benefit of making the people feel good about the overall process, which can be its own reward.
The same can work for reusable bags even without imposing bans or fines. If people don’t have reusable bags, make them available. If people are forgetting their bags in the cars, create reminders in the parking lot. If people are leaving their bags at home, supply bag hooks they can place near their doors. These create easy visual reminders to grab the shopping bags on their way out of the house.

Maybe fewer people is the real solution ? Families of 5, more groceries, more plastic. I recycle, sad to say I’m probably the only one taking plastic bags back to WalMart for that plastic bale WalMart gets paid to recycle or cardboard, foams & plastics.
When I started back in cycling to conserve fossil fuel, A co-worker asked, “What if you were the only conserving gasoline ?” As it turns out, he was right, I was wrong. The lesson was watching the protestors waste every gallon of gasoline I ever didn’t use. I was the only one going without really. And naturally the price of gasoline has only increased since then. The only benefits I see is I save money & am healthier for it, but only to be gouged for higher fuel prices because that’s just what the human race does for record profits.
We can debate the merits of recycling, the reality is saving the planet Earth, as noble as it sounds, is the last thing. Here’s another one to ponder, border crisis, more people, more plastic.

Read a study from the UK several years ago that was far more thought provoking than this filler of a story. There is another side to the big business of reusable bags entailing the negative impact of production, materials, distribution, volume and eventual burial in a landfill – each a burden to the environment in and of themselves. This is a complicated issue, ripe for virtue signalers, yet one that could benefit from truthful education, clever marketing, governmental recycling support and a concerted effort on the part of the food distributers to reduce waste.

I like the way that Europeans enforce bringing one’s own bags back to shopping. Once you’ve put everything on the checkout lane’s conveyor belt and the person at the cash register has rung it up, you can see to conveying the stuff home or pay for a fairly expensive cloth bag. Once you’ve balanced an armful to the car, you’ll never again dare go into the grocery without a bag to carry the stuff home.

Have we become so hedonistic, lazy and selfish that we can’t manage to keep a couple of reusable grocery bags in the trunk of the car. . . as a very tiny way of helping to protect our environment? What does that say about us as human beings?
Along the same line, why are we still flushing our toilets with potable drinking water, and letting the tap run while brushing our teeth? What about actual recycling, instead of allowing waste collection agencies off scot free when they charge for recycling, but put “everything” in the dump anyway?
There is so much more we could do with just a little cooperation and effort. .

Perfectly stated.
The same people who reliably mouth catchphrases and platitudes on personal, and parental, responsibility rise quickly to object to the prescription when they receive it.
An inquest about the homicide/suicide of life on Earth will not be conducted by its subject.
Yours truly, now, this moment.

Dear Pogo,
Greetings from absolutely gorgeous Simon’s Town, South Africa. We are on holiday here in this part of the world for 2 months.
When living in Flager Beach, I always wondered what it would actually be like to meet up in person, along with a few others like Ray W. I should have at least tried to make that happen before moving to Sausalito. Ahhhh, maybe in another life. In any case, I always enjoy your comments. . . especially the ones with esoteric references that require research. Thank You!
