The Atlanta-based company already offers diet drinks in most markets. But they're not always as readily available in emerging markets such as China as they are in the U.S.
With sugary sodas coming under fire for fueling obesity rates, Coca-Cola Co. has been more aggressive in trying to convince customers its products can be part of a healthy lifestyle.
A Coca-Cola spokesman says the goal is to have diet options available wherever regular versions are sold. But that doesn't mean there would be a diet alternative for every particular brand. For example, if a store in India sells Coke it might also offer Sprite Zero, which doesn't have any calories, to meet the goal.
The company says it's also working to have cans and bottles around the world display calories counts on the front of the label. The company already does that in the United States.
Earlier this year, it began airing its first TV commercial in the U.S. addressing obesity. That ad has since been rolling out to other countries.
