Coca-Cola Zero Sugar is a diet cola produced by The Coca-Cola Company. In some countries, it is sold as Coca-Cola No Sugar.
The drink was introduced in 2005 as Coca-Cola Zero as a new no-calorie cola. In 2017, the formula was modified and the name updated, a change which led to some backlash. Another formula change occurred in the UK in July 2021, in the USA in August 2021 and in Canada in September 2021.
