The United Nations Environment Programme (UNEP) stands at the forefront of global efforts to confront an escalating Triple Planetary Crisis, including climate change, biodiversity loss and pollution. The vast scale and complex nature of the challenges posed by this crisis could benefit from innovative solutions and the application of new digital technologies. In recent years, Artificial Intelligence (AI) has emerged as a transformative technology that can, if used wisely, enhance UNEP’s efforts and abilities to help Member States and other stakeholders address these challenges. The UN is monitoring the use of AI and providing recommendations and guidance to be followed. This document provides the three most recent and important guidance documents developed by the UN.
