About us

This knowledge platform is a legacy of the Water and Wastewater Companies for Climate Mitigation (WaCCliM) project, which is active until May 2019 and set out a roadmap for low carbon urban water management. The International Water Association (IWA) is maintaining this platform, powered by partners of the climate smart water initiative.


IWA works by its members and for its members to inspire change towards a water-wise world.

WaCCliM Project

Inspired by the opportunities identified in the WaCCliM pilot utilities in Jordan, Mexico, Peru and Thailand to reduce their water, energy and carbon footprints of the urban water cycle, the WaCCliM roadmap is intended to help guide other water utilities through the steps needed to ultimately reduce their greenhouse gas (GHG) emissions. It takes them through awareness raising and understanding drivers for carbon reduction, assessment of GHG emissions and opportunities to reduce them, implementing and financing projects, and monitoring.

WaCCliM Project Utilities

WaCCliM is working with pilot water utilities in four countries, developing a road map to guide them towards energy and carbon neutrality.

Our Partners

The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the International Water Association (IWA) are working together with their partners from Jordan, Mexico, Peru and Thailand on the WaCCliM project. This knowledge platform is a deliverable from the WaCCliM project, which is part of the International Climate Initiative (IKI). The German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) supports this initiative on the basis of a decision adopted by the German Bundestag.

WaCCliM works with multiple national and international partners, to address carbon and greenhouse gas emissions in drinking water and wastewater utilities.
