WaCCliM Roadmap

The transition to low-carbon urban water utilities is an innovative idea, currently embraced only by a few forward-thinking utilities. Early adopters of the WaCCliM Roadmap to a Low-Carbon Urban Water Utility are well positioned for an uncertain water-climate future. This roadmap is directed at urban water utility managers in charge of planning future actions, as well as at the stakeholders who will support the utility’s action plans.

ECAM – Energy Performance and Carbon Emissions Assessment and Monitoring Tool

WaCCliM has developed the innovative ECAM Tool to measure greenhouse gas emissions and energy performance from urban water services at a system-wide level. By identifying areas to reduce greenhouse gas emissions, increase energy savings and improve overall efficiencies to reduce costs, ECAM offers a holistic approach for urban water utilities to shift to a climate-smart and sustainable water management.

Partner Utilities

WaCCliM is working with utilities in three countries. Water and wastewater utilities partnering with WaCCliM are becoming sector leaders, and are seizing the opportunity to become more efficient and effective in an uncertain future.


WaCCliM is a joint initiative between the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the International Water Association (IWA). This project is part of the International Climate Initiative (IKI). The German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) supports this initiative on the basis of a decision adopted by the German Bundestag.
