摘要

Fluorite, as a strategic mineral resource, has yet to see its global trade-embodied carbon transfer mechanisms systematically elucidated, leading to a significant disconnect between environmental responsibility allocation and climate governance policies. This study extends the integrated framework of life cycle assessment (LCA) and complex network theory to construct a global fluorite trade-embodied carbon transfer network (FECN) spanning 2000–2022. We quantify localized carbon emissions across the entire supply chain—from mining and froth flotation to transportation—for 87 countries, while analyzing hub nations and community evolution of carbon leakage through topological metrics. Key findings include: (1) The directness of carbon transfers increased, as reflected in a shortening of the average network path length from 3.0 to 2.5, exhibiting a pronounced “core-periphery” structure where high-carbon-intensity refining in producer nations like China and Mexico accounted for 52% of embodied carbon inflows. (2) Emerging economies such as Pakistan catalyzed a structural shift from “North–South” to “South-South” carbon transfer patterns, reshaping the geography of environmental costs. (3) The EU’s network position is associated with higher resilience metrics, a pattern consistent with the diffusion of technologies that reduced partners’ carbon intensity, highlighting a potential “climate club” effect. These findings provide a structural mapping of power asymmetry in the mineral-carbon nexus and offer a scientific basis for refining cross-border carbon accounting and designing differentiated, equitable emission reduction policies that address the identified governance gaps.
