To reach the goal, Carlsberg plans to conserve all the water that is not actually used in its products not only by using water efficiently, but by re-use in its own breweries, use by other industries such as farming, or "safe return to the natural environment," the company says.

Carlsberg also committed to eliminating carbon emissions in its new sustainability program, Together Towards ZERO. Part of that commitment includes the use of 100 percent renewable electricity at its breweries by 2022. The company says the Together Towards ZERO program is a response to increasing consumer demand for sustainable products.
