Climate change intensifies the challenges faced by the water sector. Besides the services provided by water and wastewater utilities, the technologies employed by water supply and wastewater systems lead to substantial emission of greenhouse gases (GHG), which are partly attributed to water and energy losses.

The Water and Wastewater Companies for Climate Mitigation (WaCCliM) project supports water and wastewater utilities in its partner countries in identifying processes and technologies to reduce their energy and carbon footprint. In addition, the project supports the raise of awareness, capacity building and technical strengthening of key actors within the water sector, encouraging utilities to reduce their GHG emissions while adapting to climate change, thus reducing their vulnerabilities. In this regard, WaCCliM supports the utilities on the path of becoming climate friendly, while engaging with national governments and the international water and climate community.

The project developed a roadmap with systematic steps and concrete measures towards low-carbon water utilities. In this context, WaCCliM promotes the use of digital solutions such as ECAM (Energy Performance and Carbon Emissions Assessment and Monitoring Tool), a tool developed by the project and used to assess the carbon emissions, identify energy saving opportunities and monitor the GHG and energy reduction impacts of the implemented measures. ECAM provides areas for reducing emissions by considering all components of the urban water cycle, from the water supply, wastewater treatment or water reuse to faecal sludge containment, treatment and disposal. Another contribution is the development and management of a knowledge platform ‘Climate Smart Water’ that publishes and provides access to the information of the project.
