Philadelphia could soon become the first major U.S. city to adopt a tax on sugary drinks.
Mayor Jim Kenney proposed a 3-cent-an-ounce tax on soda and other sugary beverages to pay for universal prekindergarten, community schools and park improvements.
The City Council is scheduled to take a key vote Wednesday on what is expected to be a compromise measure.
The soda industry has fought the proposal with millions of dollars in advertising.
Some critics have said the tax would hit the poor the hardest.
The first-term mayor contends the poor would be among its main beneficiaries.
Philadelphia has twice failed in the past decade to pass a soda tax.
New York and San Francisco have also been unsuccessful.
Berkeley, California, was the first U.S. city to approve such a tax.
