The ICEF Artificial Intelligence for Climate Change Mitigation Roadmap (Second Edition) comprehensively updates all chapters in last year’s ICEF Roadmap (on topics including the power sector, food system and materials innovation) while adding six new chapters (on aviation, buildings, carbon capture, nuclear power, large language models and extreme weather response). Each chapter highlights 5-10 specific, actionable recommendations, providing the most detailed and comprehensive set of recommendations to date on how artificial intelligence (AI) can be used to respond to climate change.
