The Austin City Council passed a resolution Thursday encouraging local stores to keep honoring the city’s so-called bag ban. It’s the latest response to a state Supreme Court ruling this year that found Texas cities and towns could not enforce regulations of single-use plastic bags.

After the ruling, a lot of people in Austin wondered if the bags would return to local stores and, by extension, to sidewalks, creeks and tree branches. So far, it seems like little has changed. Most stores are still selling the thicker-plastic reusable bags at checkout.

The council vote amounts to a simple appeal that retailers continue with that practice.

“Plastic bags, as convenient as they may be, have a really detrimental effect on both the visual of the out of doors,” said District 7 Council Member Leslie Pool, a sponsor of the resolution. “Also [plastic] greatly harms the wildlife if they peck at it and ingest it.”

The city has also pointed to bags clogging city drainage systems as a reason to limit their use.

The damage plastics does to the environment is also gaining more attention internationally. A recent study estimated the size of a floating island of garbage in the Pacific Ocean to be twice as big as the state of Texas.

“I think everybody just realizes there’s so much out in the environment now that it’s astounding,” said Pamela Plotkin, director of the Texas Sea Grant at Texas A&M University. “You can’t go on a boat and go fishing or go sightseeing and not see plastic.”

Beyond harm to the environment, retailers may have another motivation to keep free single-use bags out of their stores: They can make money selling those thicker reusable bags.

“Large retailers are going to do what they think is best for the bottom line in a particular market,” said Rick Cofer, one of the people who spearheaded Austin’s bag ban while serving on what was then called the Solid Waste Advisory Commission.

It's unknown how much Austin stores have made by selling reusable bags, but similar bans in other cities have shown it can be lucrative. In California, an analysis found requiring stores to sell reusable bags brought in "tens of millions of dollars."

A small fee on plastic bags in Dallas that lasted only about five months brought in around $500,000 to a city environmental program.

One interesting fact found in the council resolution to be voted on today: During the five years Austin’s bag ban was in place, not a single fine was levied against any business for violating it.
