Materials Powering the Future of Energy

The Critical Materials Monitor aims to improve understanding of supply chains essential for the energy transition, the transition to more sustainable energy. It offers insights into the critical minerals required, outlines the components of key technologies, and provides in-depth reserve, production, and trade analysis.

Critical minerals overview

Share of total world production, 2022

2/56

The United States Geological Survey (USGS) publishes annual summary reports that provide estimates of reserve and production statistics for individual minerals and materials in specific countries. Reserves refer to the economically extractable or producible portion of the reserve base at the time of assessment. Production signifies the amount of a mineral or material that has been extracted or manufactured within a certain period.

Trade of mineral related commodities, 2023

Material-related commodities are classified into four groups, two of which are shown here: Raw (unprocessed mineral ore in natural form), Processed (processed or purified mineral ore).

You can find a full list of commodities described in the corresponding mineral page. This graph illustrates the aggregated annual imports and exports of the country for the selected critical mineral, as well as top trading partners.

Raw materials

Overall import value (USD)
$2.1B
Overall export value (USD)
$350M

Processed materials

Overall import value (USD)
$753M
Overall export value (USD)
$2.9B

* Includes one or more commodity codes that include multiple minerals. The data does not allow identification of the percentage of trade for each mineral.

† Includes one or more commodity codes that include multiple production stages (raw, processing, products, and waste/scrap). The data does not allow identification of the percentage of trade for each stage.

Trade of technology related commodities, 2023

Technology-related commodities are classified into three groups:: Midstream (chemical and material inputs of technology components), Downstream (fully assembled components or products), and Waste/Recycling (including recycled or waste products and components). Commodities are further arranged according to the relevant technology components.

This graph presents the reported import and export value of the country for each relevant commodity, as well as the resulting trade balance.
