A new approach: Assessing the vulnerability of critical raw materials in the automotive industry

In the automobile industry, the development and manufacture of increasingly complex technological components — catalytic converters, LEDs, electric motors, batteries — requires increasingly complex and diverse raw materials with specific qualities. The technological and economic importance of these materials, combined with their vulnerability to supply shortages and likelihood of supply interruptions, indicates their ‘criticality’. This study uses a new methodology to explore the criticality of 27 key metals used in the automotive industry and other sectors, and highlights six that are especially vulnerable: rhodium, dysprosium, neodymium, terbium, europium and praseodymium. The researchers found there was limited recycling and substitution of these metals and a high possibility of restrictions to their supply.
