Yesterday was World Water Day, which means that throughout the day you probably heard or read at least one message about drinking tap water, turning off the tap while brushing your teeth, or other water saving actions that you can all take to conserve water and alleviate the global water crisis. And if you’re interested in sustainable business, then you probably also heard or read plenty of things about what businesses are doing to reduce their water footprints.

Here’s a quick summary of the highlights:

– PepsiCo has reduced its water use (per unit of production) by more than 15%
– Coca Cola and the U.S. Agency for International Development have jointly invested $12.7 million on water scarcity and quality projects in Africa
– Nestle Waters and Project WET are working together on an youth-centered education campaign to increase awareness about water quality and sustainability
– The World Wildlife Fund and the water treatment company Nalco have partnered to develop water stewardship standards to promote the conservation of water

A few months ago I attended the second annual Corporate Water Footprinting Conference, where speakers from Patagonia, PepsiCo, Intel, Nestle Waters and more–as well as organizations such as Food & Water Watch and the Blue Planet Foundation–presented on the latest developments in operational and supply chain water efficiencies.

At the water conference, I learned about the great efforts that these multinational corporations are making to reduce their water footprints. It makes sense for them financially, as well as socially: more and more consumers are pressing companies to be more green, or sustainable.

For example, Raisio, a Finnish company that produces various consumer packaged goods, is the world’s first food company to add a water label to product packaging that indicates the total water consumption of the product.

Maybe next year on World Water Day we’ll see an American company do the same!
