Water and wastewater companies are typically energy intensive. This indicates excellent opportunities for improving energy efficiency and greatly reducing greenhouse gas emissions through more energy-efficient systems, as well as recovering energy, nutrients and other materials from wastewater.

The ‘Water and Wastewater Companies for Climate Mitigation’ (WaCCliM) project shows how the urban water sector can reduce its own greenhouse gas emissions while preparing for climate change. WaCCliM engages with the international water and climate community, with national governments and with water and wastewater utilities as well as their associations in Jordan, Mexico and Peru. Together with its national and local partners, WaCCliM is improving the carbon balance of utilities in these countries and beyond. At the same time, the project aims to ensure that utilities increase their climate resilience, reduce their operational costs, and maintain, improve and adapt their services.
