Formed in 2022, the Climate Resilient Sanitation Coalition (CRSC) is a growing coalition of international organizations, global research organizations, and practitioners in the fields of water and sanitation. The coalition launched a Sanitation Call to Action at COP27, calling on all stakeholders to work collectively to ensure the resilience of sanitation systems to maximize the public health outcome and explore the opportunities of reducing emissions along the sanitation service chain. Among its members are UNICEF, the World Bank, the World Health Organization, the Bill and Melinda Gates Foundation, WaterAid, the Asian Development Bank, the African Development Bank, and many other research institutions and funds.
