Sustainable water strategies

Listened in on a fascinating presentation this week: Achieving Sustainable Water Strategies: Diageo Case Study by Roberta Barbieri, Global Environmental Project Manager at Diageo – courtesy of the 2degreesnetwork.

Interesting way to break down the problem – look at sustainability under sourcing, production, distribution and packaging.

As an example of use of water, in the talk Roberta referenced some research showing that it takes 160L of water from barley in the field to finished goods out the door to make a bottle of Tusker beer.

As a group Diageo has established water efficiency targets – against which it reports each year.  They are seeking 30% water efficiency gains between 2007 and 2015 – across the full network of Diageo plants.  In addition they are seeking to reduce water waste by 50% in all plants located in water stressed zones.

Roberta outlined some excellent examples of recent plants – Cameronbridge in Scotland and St Croix, US Virgin Islands – seeking to eliminate water waste,

Interesting to see how a global company looks at the water crisis facing all of us – and attempts to tackle this through a water sustainability strategy.
