Although sanitation systems are fundamental for human health and sustainable development, limited focus has been placed on their contributions to climate mitigation and adaptation. Climate change threatens existing systems, as well as efforts to increase services for 2.3 billion people who lack even a basic sanitation service. At the same time, the sanitation and wastewater sector directly produces emissions associated with breakdown of organic matter, and treatment processes require large energy inputs. In light of these challenges, we describe gaps in how sanitation is being addressed in mitigation and adaptation, discuss how this results in little inclusion of sanitation in climate policy and financing at the global level, and implications of these gaps for different sanitation systems and geographic regions. Finally, we describe the need for planning frameworks to facilitate integration of climate change into sanitation policy and programming. This will be critical to increasing understanding of sanitation and climate change linkages among stakeholders, and more effectively including sanitation in climate action.

尽管卫生系统对于人类健康和可持续发展至关重要，但对它们对缓解和适应气候变化的贡献的关注却很少。气候变化威胁到现有系统，并努力增加为甚至没有基本卫生服务的23亿人口提供的服务。同时，卫生和废水部门直接产生与有机物分解相关的排放，处理过程需要大量的能源投入。鉴于这些挑战，我们描述了在缓解和适应方面如何解决环境卫生方面的差距，讨论了如何在全球范围内将环境卫生很少纳入气候政策和融资，以及这些差距对不同环境卫生系统和地理环境的影响。地区。最后，我们描述了需要规划框架以促进将气候变化纳入卫生政策和规划的需求。这对于增进利益相关者之间对环境卫生和气候变化联系的理解，更有效地将环境卫生纳入气候行动至关重要。
