Water-Energy Nexus

The business world is quickly beginning to understand the intersection of the water sector and the energy sector and the significant impact they have on business operations.

On 11 December 15, the U.S. Chamber of Commerce Foundation (USCCF) Corporate Citizenship Center hosted The Energy-Water-Food Nexus: Risks and Opportunities for the Private Sector, the second in a series of roundtables based on a report released earlier this year. The USCCF’s report and surrounding events are highlighting success stories and, more importantly, opportunities for the business community to address the energy-water nexus: the idea that energy and water use are fundamentally intertwined. In order to accurately address water risks across operations and supply chains, businesses must take a more holistic look at their water and power usage.
