| 英文摘要 | With the acceleration of globalization and international trade, aluminum, a key industrial metal, faces increasing concerns over its embodied carbon emissions (ECEs) in production, consumption, and trade. However, most studies examine aluminum flows at the industry level, the issue of ECEs pathways of aluminum in international trade, particularly through upstream and downstream linkages in the value chain, has not been thoroughly studied. This study addresses this gap by utilizing the Exiobase 3.3 database and industrial linkage decomposition techniques to provide a comprehensive analysis. The findings suggest that: (1) From 2002 to 2022, global aluminum trade's ECEs fluctuated, decreasing from 33.18 Mtce in 2002 to 26.39 Mtce in 2012, then increasing to 32.51 Mtce in 2022. Net exporter countries established direct connections among core regions, such as the United States-Brazil-China, the European Union-Africa-China, and the Middle East-Australia-China. (2) Foreign final demand in international trade drives 64.51% of total emissions in 2022, with manufacturing giants like China and the EU contributing to downstream emissions, and resource-rich nations impacting upstream segments. (3) A country's position in the global value chain influences its exported ECEs, with higher downstream participation leading to more domestic CO2 in exports. (4) Economies are categorized into upstream resource-based, midstream processing, downstream manufacturing, and comprehensive types, based on ECEs patterns and value chain positions, and for each type, unique carbon challenges are identified along with tailored strategies proposed. This research provides vital data for carbon reduction policies and international trade regulations. |
