This report, produced jointly by IUCN and the World Business Council for Sustainable Development (WBCSD), identifies 16 initiatives or tools for water management, 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. This guide is aimed at helping business identify which initiatives and approaches will most suit its needs, and to help developers of schemes understand opportunities for increasing impact through consensus building and joint action.
