Evaluating the inclusion of sanitation and wastewater in climate policy and finance

Abstract: Sanitation is critical for sustainable development. However, the current systems in place are vulnerable to future risks. One of the main risks expected to have severe effects on the earth systems and our societies is climate change. If not dealt with, it threats to hinder or even reverse the progress done in sanitation access so far. On the other hand, countries are lacking the financial capabilities to achieve the sustainable development goals related to sanitation, not to mention the additional costs needed to increase its resilience towards climate variability and extreme weather conditions. Nevertheless, sanitation is not only vulnerable to climate change, it is also a significant contributor to greenhouse gas emissions which drive climate change. It is therefore important to better understand the linkages between sanitation and climate change. The aim of this study is to evaluate the inclusion of sanitation in climate policy and finance. A secondary content analysis is used to identify interest in sanitation in countries’ Nationally Determined Contributions to the Paris agreement. Climate-related official development assistance flows and financial elements of approved project proposals by the Green Climate Fund board are analyzed to quantify climate finance flows supporting sanitation projects. The results indicate that sanitation is largely ignored in countries’ climate agendas constituting only 1% of all countries’ activities with very scarce mitigation activities for the sector. Furthermore, sanitation is marginalized in the international climate finance landscape. Very limited climate-related finance from official development assistance was found allocated to projects with the main focus on sanitation. As for the GCF approved project proposals, only 7 projects out of 99 had sanitation or wastewater-related components and only one project of the 7 received GCF funding. These results indicate a knowledge gap of sanitation’s potential contribution to emissions reduction and the risks from climate change towards sanitation systems. Furthermore, it points out the need for better coordination between development and climate finance in order to reduce the finance gap and help achieve the sustainable development goals and the Paris agreement simultaneously.
