Wastewater is a growing health and environmental threat, accounting for almost as many planet warming emissions as the aviation industry. Yet, with the right policies, wastewater could be an invaluable resource, providing alternative energy to half a billion people, supplying over 10 times the water provided by current global desalination capacity and offsetting over 10 per cent of global fertilizer use.  

This new report, “Wastewater - Turning problem to solution”, developed jointly by UNEP's Global Wastewater Initiative and GRID-Arendal, urges decision makers and action takers from all regions of the world to implement the three key actions, to overcome barriers, and to put in place the building blocks, described in the publication.
