Climate Mitigation Technologies–Perspective Based on Patents

Abstract

Indian Government has made global commitment to reduce the emissions by 33% to 35% by year 2030. To achieve this target, interventions and improvements in the existing technologies being used would be needed. In this paper using patent data, an effort has been made to find out the trends in the technologies relating to climate change mitigation. The focus of majority of these technologies is to capture and separate carbon dioxide. Majority of these technologies are originating in USA and Japan. It was observed that with 237 patents/applications, L’Air Liquide is the top assignee in the area. In recent years, the leader is challenged by new entrant Altsom Technology, who has been aggressively filing patents and has overtaken L’Air Liquide. The paper reveals major patent owners in various technologies relating to climate change mitigation and this information would be helpful in seeking licenses and partnerships or for scouting for the technologies to meet the commitment to reduce the emissions.
