Mapping critical raw materials in green technologies
This paper provides an exploratory analysis of the relationship between critical raw materials (CRMs) and environmental technologies. Using text mining techniques to parse and analyse patent data, we explore: (i) the dependence of green technologies on CRMs; (ii) the countries that are more reliant on CRMs in their green patent portfolios; and (iii) the connections between major users and suppliers of CRMs. Framed in the context of recent policy debates on the viability of the sustainable transition, our study points to the criticalities of both the evolution of green technology and of the spatial distribution of demand and supply of CRMs.
