City Council members introduced a bill Wednesday that would impose a 10-cent fee on plastic and paper bags.
The measure is intended to spur shoppers to bring their own reusable bags.
New York City residents use 1 billion disposable plastic bags a year. It costs the city $10 million annually to ship used bags to landfills.
Similar measures are in place in Los Angeles, Seattle and Washington, D.C.
A vote is expected in the next few weeks. A similar measure failed last year.
Former Mayor Bloomberg also proposed a failed 5-cent plastic bag tax in 2009, which would have required approval from state lawmakers. Under the council proposal, the 10-cent surcharge would be pocketed by retailers, rather than the city.
Mayor de Blasio on Tuesday called plastic bags "a problem" but stopped short of endorsing the bill.
