As people increasingly try to lessen their impact on the environment by conserving energy and water, many companies – including some of the large multinationals – are following suit.

This week in the Swedish capital, environmental sustainability was in focus for hundreds of delegates at the World Water Week conference where topics ranged from how best to achieve food security for almost 1 billion people who currently go hungry to corruption in the water sector and how to provide adequate sanitation for 2.5 billion people who lack it.

Among the water-sector achievements honoured with awards at the annual conference, PepsiCo, the maker of Diet Pepsi, Gatorade, Frito-Lay snacks and Tropicana orange juice, snatched up the prestigious Stockholm Industry Water Award for increasing water efficiency in its own production facilities and working to defeat water problems on a larger scale. PepsiCo has net revenues of more than $65 billion and 300,000 employees around the world.

“PepsiCo’s water commitment has not stopped at the factory walls,” said a press release from the Stockholm International Water Institute (SIWI), which hosts the awards.

“By assisting farmers in growing more water-efficient crops, implementing better agricultural practices and irrigation techniques, and by supporting watershed management initiatives, PepsiCo has saved water all along its agricultural supply chain.”
