PepsiCo, the food and snack company, on Thursday laid out a broad range of steps aimed at reinvigorating its US soft-drink business, including a redesign of its flagship cans, and the launch of its first drinks using a low-calorie natural sweetener.

The new Pepsi brand design, which will be launched in the new year, comes as both PepsiCo and Coca-Cola face a continuing decline in consumption of sparkling drinks, as consumers switch to juices, teas and enhanced water.
