Climate Resilient Sanitation Coalition (CRSC)

Sanitation and the climate crisis are intrinsically interlinked. Sanitation systems are vulnerable to climate events that damage infrastructure, disrupt services, and displace people. This results in increased health risks and pollution that impacts ecosystems, with low-income and marginalised populations disproportionately impacted. Additionally, poorly managed sanitation is a significant greenhouse gas emitter, particularly through methane emissions from latrines and septic tanks.

• Health: Loss of sanitation service due to floods and droughts disproportionately affects incidence of diarrheal disease – cholera countries, cases, frequency and size of outbreak have all increased dramatically in recent years. Change in temperature is also causing vector-borne diseases, such a dengue fever, to thrive especially where wastewater management and drainage are poor.
• Institutions: Sanitation in schools and health care facilities is vulnerable to climate hazards such as flooding and sea level rise which damage infrastructure. This puts students, teachers, patients, family members, doctors, nurses, etc. at elevated risk of being exposed to diarrheal diseases. Climate events disrupt the education of 40 million children each year.
• Marine Ecosystems: Damaged sanitation systems release sewage into marine ecosystems, damaging mangrove forests, coral reefs, and seagrass beds. These ecosystems sequester carbon at 35 times faster than terrestrial forests.
• Emissions: Poorly managed sanitation is a significant greenhouse gas (GHG) emitter, primarily through methane from sludge. One assessment estimated that nearly 50% of a city’s GHG emissions came from sanitation.

To address this situation, in 2022 the Climate Resilient Sanitation Coalition was launched in response to the joint Call to Action launched at COP27. The Coalition was formalised under the vision of:

Integrating sanitation into global and national climate policy & practice; and integrating climate into global and national sanitation policy & practice.

The coalition is a growing collaboration of international organisations, research organisations and practitioners working collectively towards improved prioritisation, capacity and investment in climate resilient sanitation. Currently Coalition members represent almost 35 organisations implementing climate resilient sanitation (CRS) programs in almost 80 countries.

Activities 

Operating at a global level, the Coalition currently has five workstreams:

1. Integrate sanitation into global and national climate policy and practice (e.g., development of a sanitation annex for the GCF Global Guidelines).
2. Support national governments with tools, evidence, and expertise to incorporate CRS into government policies, plans, and strategies (e.g., National Adaptation Plans and Nationally Determined Contributions).
3. Increase the prominence of sanitation in climate discussions through active dissemination of evidence and experiences.
4. Attract finance to the climate resilient sanitation sector, including developing the relevant climate rationale.
5. Build the evidence base for climate resilient sanitation, including in connection with adjacent sectors (e.g., water supply, solid waste management, agriculture, ecosystem management, education, health, environment, etc.).
