Abstract：Coal is an important fossil energy source and industrial raw material.Rapid socio-economic development and globalization have led to coal scarcity.However,the driving mechanism of global supply chains to coal mining scarcity(e.g.,key regional sectors and key trade relationships)remains unknown.This cannot provide hotspots for policy decisions to mitigate coal mining scarcity.This study quantifies coal mining scarcity in each region from the production side.Key regional sectors and trade relationships in global supply chains driving coal mining scarcity from the consumption and betweenness sides are identified based on global environmentally extended multi-regional input-output model.The results show that the United Kingdom and Norway are among the most prominent regions facing coal mining scarcity from the production side.From the consumption side,"Public administration and defence services"sector in Romania is an important driver of global coal mining scarcity.From the betweenness side,the"Coke oven coke"sector in China is an important transmitter of the embodied coal mining scarcity in global supply chains.This study also identifies key domestic and international inter-sectoral trade relationships.The findings provide hotspots for policy decisions on the mitigation of global coal mining scarcity.They also lay scientific foundation for the interregional and inter-sectoral cooperation to reduce global coal mining scarcity.
