Life cycle assessment, a comprehensive tool to evaluate environmental impacts across a product’s life cycle,traditionally focuses on "inside-out" impacts caused by the product on the environment, emphasizing resourceuse, global warming, and other environmental impacts. In contrast, the "outside-in" perspective considersresource availability and accessibility to industry. This second perspective was developed as a way to integrateraw material criticality assessment into LCA. The GeoPolRisk method assesses the supply risk based on globalproduction concentration, import shares, political stability scores, and the average price of the commodity. Thisarticle introduces a characterization model for the GeoPolRisk method and calculates the Geopolitical SupplyRisk Potential of using 46 raw materials across different countries in multiple years. The characterization factorsshow the highest values for precious metals, like platinum group metals (PGMs), reflecting their high marketprices and concentrated production in geopolitically unstable regions. The results emphasize the significance ofspatial and temporal variations in characterization factors, providing a nuanced assessment of supply risk of rawmaterials associated with the product system. Despite data limitations, the characterization factors offer a goodestimate of the supply risk of raw materials available for use in product systems. A case study on photovoltaiclaminate production highlights gallium, copper, and tin as significant contributors to supply risk. From an"outside-in" perspective, the case study demonstrates how the GeoPolRisk method complements traditionalenvironmental indicators such as global warming, making it a valuable tool for assessing mineral resource supplyrisk in Life Cycle Assessment.
