The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the International Water Association (IWA) are working together with their partners from Mexico, Peru and Thailand on the WaCCliM project to improve the carbon balance of water and wastewater utilities in the three countries and beyond.

This project is part of the International Climate Initiative (IKI). The German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) supports this initiative on the basis of a decision adopted by the German Bundestag.
