The challenge of achieving net zero CO2 emissions will require a significant scaling up of production and international trade of several raw materials which are critical for transforming the global economy from one dominated by fossil fuels to one led by renewable energy technologies. This report provides a first joint assessment of data on production, international trade, and export restrictions on such critical raw materials from the OECD’s Inventory of Export Restrictions on Industrial Raw Materials covering the period 2009-2020. It presents data on production and trade concentrations, sheds early light on the impact of export restrictions, and discusses possible directions of further work in this area. The evidence presented suggests that export restrictions may be playing a non-trivial role in international markets for critical raw materials, affecting availability and prices of these materials. OECD countries have been increasingly exposed to the use of export restrictions for critical raw materials.
