SDG 13, or Climate Action, is a United Nations goal to take urgent action to combat climate change and its impacts, including strengthening resilience to disasters, integrating climate measures into policies, and improving education and awareness. It is crucial for the success of all other Sustainable Development Goals (SDGs), as climate change threatens to exacerbate poverty, conflict, and ecosystem degradation. Key targets involve limiting global warming, adapting to climate-related risks, and enhancing capacity for climate planning, especially in the least developed countries.
