Antoine Dechezleprêtre, Ilja Rudyk (European Patent Office), Yann Ménière, Gerard Owens, Alessia Volpe & Robert Ondhowe, “Climate Change Mitigation Technologies in Europe – Evidence from Patent and Economic Data”
The study analyses the position of Europe in the global development of new climate change mitigation technologies (CCMTs), its importance in the dissemination of CCMTs and the role of European climate change policies. Using a comprehensive dataset on patent applications, trade in CCMT capital goods, foreign direct investment in CCMTs, climate change policy stringency, carbon emissions and public expenditure on CCMT research and development activities, we investigate inventive and associated economic activity in CCMTs in Europe. The main source of data to identify CCMT-related inventive activities was the Worldwide Patent Statistical Database (PATSTAT), developed by the European Patent Office (EPO). This publicly available database is the world’s largest repository of patent information, containing data on over 82 million patent applications. The EPO has developed a dedicated classification scheme for CCMTs (using the Y02 and Y04S tags) that makes it possible to analyse CCMT-related trends in inventive activity and in the global technology market, and to provide evidence to support public and private decision-making.
