European Water Stewardship (EWS)
To support the implementation of responsible and sustainable water management of water using companies, the EWP created the European Water Stewardship (EWS) in 2008. The EWS is an integrative system for business and agriculture to assess, verify and communicate sustainable water management practices. It supports to develop a sustainable water strategy and provides all the necessary information to make it reality. The EWS water audit has been tested within the INNOWATER project.
