Greenhouse gas (GHG) emissions are driving climate change, directly impacting the availability and quality of water, and posing an increasing burden on cities to maintain water security. While the water sector has to cope with the impacts of climate change, it also contributes to 5% of global CO2 emissions from energy consumption as well as methane and nitrous oxide emissions from wastewater. Climate change mitigation measures by water and wastewater utilities (WWUs) are being set into motion through the WaCCliM project which works with WWUs in emerging economies, where emissions are the highest due to a large portion of untreated or poorly treated sewage.

This session introduces the Energy Performance and Carbon Emissions Assessment and Monitoring (ECAM) Tool, a carbon accounting tool for WWUs. ECAM can be used to calculate GHG emissions and identify potential areas to reduce GHG emissions considering all components of the urban water cycle from water supply, wastewater treatment, sludge management and discharge. Furthermore, two case studies will be presented from Jordan and Peru, showing the link of climate change mitigation and resource efficiency.

The event “Water to mitigate climate change: beyond the obvious” will take place during the World’s Leading Trade Fair for Water, Sewerage, Waste and Raw Materials Management (IFAT), in Munich, Germany, in Room B2.227/326. Register for the event here!
