How Behavioral Science Solved Chicago's Plastic Bag Problem


In 2016, the city of Chicago “became a municipal laboratory” to test the different ways to disincentivize the use of plastic bags. The city initially attempted eliminating plastic bags, which led to more paper waste. Then it levied a plastic bag tax of 7 cents, an effective behavioral nudge that decreased plastic bag use and increased city revenue. The effort is now spreading across Illinois, as part of a growing trend of decreasing plastic usage across the country.
