The Alliance for Water Stewardship (AWS) has launched in March 2013 the first International Water Stewardship Standard. The AWS Standard is designed to give companies and utilities a roadmap to follow towards sustainable water use, including engagement with stakeholders and others within their watershed. The Standard is designed to be applicable in all sectors and all regions.
