Tracking AI in climate innovation
Abstract Innovation in artificial intelligence (AI) is spreading rapidly in many areas of technology, and AI technologies may be of help to mitigate and adapt to climate change. However, previous studies of AI in the climate context mainly rely on expert judgement of the research literature, not large-scale data. Here, we present a new approach to analyzing the relation between AI and climate innovation on the economy-wide scale. We analyze over six million patents from the past 45 years from the United States, and find that the greatest amount of climate AI innovation has occured in transportation, energy, and manufacturing technologies. Green ICT and climate adaptation technologies is where AI innovations have higher shares, and breakthrough innovations have made up a larger share in adaptation technologies compared to technologies for climate mitigation. We estimate the difference that AI makes with statistical analysis: AI in mitigation and adaptation technologies is associated with 30-100% more subsequent innovations. Our approach provides new capabilities to track the exponential growth of AI in climate innovation.
