Coke said its global sales volume rose by one per cent. But that was only because of overseas sales strength. In North America, carbonated drink sales fell three per cent.

Like Pepsi, which reported a "mid-single-digit" drop in soda volume last week, Coke has been battling declining pop sales in developed markets, especially in the United States.

Americans has been trimming their consumption of carbonated beverages for years amid worries over sugar or artificial sweeteners. There's also more competition from energy drinks.

Coke has been trying to grow its business in emerging markets. It also bought a stake in Green Mountain Coffee Roasters earlier this month.
