“Water for Business: Initiatives Guiding Sustainable Water Management in the Private Sector” is a report jointly developed by the World Business Council for Sustainable Development (WBCSD) and the International Union for Conservation of Nature (IUCN). The report identifies 16 initiatives or tools, driven by business leaders, civil society and governments, which have emerged since 2006. It includes the WBCSD Global Water Tool, which helps companies map their water use and assess water risks and opportunities across their global operations. Water for Business is not an exhaustive overview; rather, it tries to concisely capture business-relevant initiatives that are addressing the challenge of better defining sustainable water management. These can be through different approaches, including guidelines, tools, measurement methodologies, and communication and stewardship schemes.
