PROVIDENCE, R.I. (AP) — Providence's city council is considering a measure that would impose a fee on plastic shopping bags to encourage customers to use reusable bags instead.

WPRI-TV reports that council member Jo-Ann Ryan proposed the ordinance Wednesday night. She says it would reduce litter, protect marine life and cut back on greenhouse gas emissions. She also thinks it could save the city $1 million a year.

Exceptions to the rule would include dry cleaning bags and bags for frozen food.

Retailers would be allowed to keep the bag fee. Some already impose fees, starting at about 25 cents.

Several other communities in Rhode Island have passed outright bans on plastic bags.
