Beverage companies fight latest soda tax proposalÂ

Look at it this way: Under this proposal, there would be a 36-cent tax on a 12-ounce can of soda.

The city council will not vote on the matter until June, but beverage giants Coca-Cola and Pepsi have been united against it from the start.

Rather than trying to reduce how much soda people drink for health reasons, Mayor Jim Kenney says the tax will fund universal pre-K and other projects, adding up to $400 million over five years.
