Water is necessary for many key climate mitigation measures, including for the clean energy transition and the natural and artificial removal of carbon dioxide from the atmosphere. Understanding water availability and constraints should assist in deciding on climate mitigation options and guide the design of climate mitigation projects. As countries review and update their NDCs, now is the time to understand how action on water and sanitation can contribute to climate solutions.

 The UN-Water Analytical Brief on Water for Climate Mitigation discusses the dependency of climate mitigation on the use of water and the effective management of water resources and related services to ensure sustainable and effective outcomes.
