Philadelphia Mayor Jim Kenney signed the city's 1.5-cent-per-ounce tax on sugary and diet beverages Monday.
Pre-K students and advocates joined Kenney at the signing at City Hall.
The City Council approved the new tax -- considered a setback to the beverage industry, which had successfully beat back similar initiatives in other big cities and states in recent years -- on a 13-4 vote. It is set to take effect Jan. 1.

The tax will be levied on distributors. If they pass it entirely on to consumers, the cost of a 12-ounce can of soda would go up 18 cents. A six-pack of 16-ounce bottles would go up $1.44.
Berkeley, California, is the only other city with a similar law on its books, though Chicago has for years had a 3 percent city tax on retail soft drink sales and a separate tax on fountain drinks.
Soda tax proposals like Philadelphia's have failed in more than 30 cities and states in recent years, including twice in Philadelphia. Such plans are typically criticized as disproportionately affecting the poor, who are more likely to consume sugary drinks.
Kenney, a Democrat, sold the council on the idea with a plan to spend most of the estimated $90 million in new tax revenue next year to pay for prekindergarten, community schools and recreation centers.
"Thanks to the tireless advocacy of educators, parents, rec center volunteers and so many others, Philadelphia made a historic investment in our neighborhoods and in our education system today," he said last week.
The tax was a hard-fought win for the city. The soda industry spent millions of dollars in advertising against it, arguing it will be costly to consumers. The plan also attracted national attention and dollars, with former New York Mayor Michael Bloomberg and Texas billionaires John and Laura Arnold, advocates for less consumption of sugary drinks, funding ads in support.
The American Beverage Association called the soda tax "discriminatory and highly unpopular."
"The tax passed... is a regressive tax that unfairly singles out beverages, including low- and no-calorie choices," it said a statement.
The association and beverage bottling businessman Harold Honickman promised to fight the tax in court, with Honickman saying the tax would mean sales will go down and jobs will be lost. Teamsters Local 830 secretary-treasurer Daniel Grace agreed a legal battle is ahead.
Many communities where soda tax proposals have failed sought it as a way to discourage consumers from buying sugary beverages for health reasons. [[383367491, C]]
The case could certainly be made for a healthier Philadelphia, where more than 68 percent of adults and 41 percent of children are overweight or obese. But Kenney focused on public interest over public health.
He said earlier that Americans generally reject other people telling them what's healthy for them, so his administration tried to stay away from that. He said any health benefits coming from the tax are a bonus.
Though the tax won't start getting collected until 2017, it will be included in the fiscal budget that starts July 1.
Some of the money raised by the tax will go to pay for city employee benefits and pet projects of council members and to boost municipal budget reserves.
