NEW YORK Philadelphia Mayor Jim Kenney scored a victory that had eluded more than 40 U.S. public officials who took on the powerful U.S. soda industry when the city council voted on Thursday to slap a tax on sweetened drinks. After a bitter, months-long battle, the city council voted 13-4 to approve a 1.5 cent-per-ounce tax on sugary and diet drinks beginning in January. The council already approved the plan in a preliminary vote last week, and the outcome had not been expected to change.
