Urban sanitation systems – both onsite/fecal sludge management and sewers/wastewater management – contribute to GHG emissions, both directly through the breakdown of excreta discharged into the environment or during treatment processes, and indirectly through the energy required for the different waste transportation and treatment steps along the sanitation service chain.

The range of mitigation and adaptation interventions related to urban sanitation systems indicate that opportunities for (a) undertaking climate-positive actions and (b) leveraging climate financing for sanitation are currently seriously overlooked. This session will explore how best to: (i) facilitate understanding of, and opportunities for, urban sanitation-related climate financing; and (ii) prepare and implement urban sanitation projects that maximize equitable access to sanitation through resilient, low emission systems.
