Anheuser-Busch InBev has become the most efficient in terms of water use among global brewers, based on publicly available data provided by these brewers, as of May 30

The designation was achieved by reaching an industry-leading water use ratio of 3.2 hectoliters per hectoliter of production, according to the company. From 2013 to 2014, this resulted in saving the equivalent of the amount of water it takes to make more than 4 billion cans of our beers.

In addition to the work done within its brewery walls, the company also engages in a comprehensive water stewardship program, including watershed protection measures in brewery communities facing water stress and working with barley growers to obtain the most crop per drop, according to the company. The efforts aim to improve the quality and quantity of available water for all users.

This announcement coincides with AB InBev’s 7th global celebration of the United Nations Environment Programme’s World Environment Day.

This year, the company is putting a particular emphasis on the issue of water, a critical input to AB InBev’s products and a vital resource to its communities around the world, according to a press release.  To demonstrate its commitment to collectively tackling environmental challenges inside and outside its brewery walls, AB InBev is joining together for the first time in a common initiative — a Global Walk for Water.

Colleagues will log steps and charitable donations to drive awareness of water issues in their communities.
