The UN Climate Change’s Initiative on Artificial Intelligence for Climate Action (#AI4ClimateAction) explores the role of AI in advancing climate action in developing countries. AI-powered solutions, such as early warning systems for disasters and optimization of agri-food systems, are already being implemented. AI algorithms can also improve the efficiency and reliability of renewable energy systems. The UN Climate Change Technology Executive Committee (TEC) will hold a high-level event on AI for climate action at COP28.
