Abiotic resources are indispensable in society, but there concerns regarding their depletion, scarcity, and increasing prices, resulting potential economic damage the future. To address these concerns, it is effective to consider external costs of resource use. Although availability different among mining sites, local conditions relevant assessing previous studies have assessed impacts abiotic use globally. This study provides country-specific characterization factors (CFs) life cycle impact assessment based on user cost model, which represents reflect scarcity. We demonstrate considerable variations CFs depending country, suggesting that choice country can affect costs. The global 2020 was estimated at 1.9 trillion $, with a major contribution from extraction fossil fuels United States. Historical trends parameters showed temporal fluctuations, emphasizing importance regularly updating data underlying calculation CFs. Country-level assessments contribute discussions responsibilities consuming countries by incorporating material footprint studies.
