More Than One Way to Save Water

SYDNEY - May 25/05 - SNS -- Conserving water is not as simple as taking shorter showers, say Australian researchers, who found vast quantities of water are used to manufacture fruit juices and dairy products.

Balancing Act, a report by scientists from CSIRO and the University of Sydney, found the glass of juice you have for breakfast might have used the same amount of water in its production as the amount you have just saved by cutting your shower from 10 to 5 minutes. The milk on your cereal might have used even more.

Report co-author CSIRO scientist, Barney Foran, says that sustainability for Australia and elsewhere is a balancing act as we try to make decisions and trade offs in the face of often-competing economic, social and environmental attributes.

"We still need to eat and shower - and it is still worth taking shorter showers to save our stressed urban water supplies - but now consumers have a new tool to help us make more informed choices about different types of products based on a new sustainability rating," says Foran.

This work will help government, industries, and even individual consumers to look at the resource impact of different goods and services in a whole new light. Different to other studies because of its detailed scrutiny of the full production chain, this report is able to show the full effects - both direct and indirect - of the production of an individual commodity or service, cappuccinos or haircuts.

Balancing Act uses ten social, environmental and financial indicators. The social indicators are employment, income and government revenue. The environmental indicators are water use, land disturbance, greenhouse gas emission and energy use. The financial indicators are profits, exports and imports.

This report is significant because it highlights sustainability challenges for different industries and pinpoints areas in the production chain where a focussed effort would make a significant difference.

All effects are referenced back to a consumption dollar - roughly the dollar spent by a consumer in everyday life. It also shows that each consumption dollar is quite different - some dollars are positive and create employment, or suck in imports or generate government revenue. Other consumption dollars are less positive through their high use of water or production of greenhouse gas emissions.

This relatively simply presentation of highly complex issues make this a powerful tool for people in industry, government and the community who are interested in sustainability to move beyond decisions based on dollars and cents and enable them to make decisions based on a contribution to society, environment, and economy.
