本研究は、銅生産に伴う温室効果ガス排出量を定量化し、EU排出量取引制度（EU-ETS）と炭素国境調整メカニズム（CBAM）が銅コストに与える影響を分析。ポーランドは排出量が最も低いにもかかわらずEU-ETSで最も罰則を受け、中国は排出量が多いにもかかわらずコスト負担が最小であることを発見。銅をCBAMの対象に含めることで排出とコストのバランスが改善される可能性を示唆。
English
This study quantifies GHG emissions from copper production and examines the impact of EU-ETS and CBAM on copper costs across different countries. Results show Poland, despite lowest emissions, faces highest EU-ETS penalties, while China with high emissions faces minimal costs due to allocation rules. Including copper in CBAM could balance emissions and costs.

日本のGX文脈において
日本は銅の主要輸入国であり、CBAMの対象拡大は日本企業のコストに直接影響する。本研究は、EUの炭素国境調整政策がサプライチェーン全体に与える影響を定量的に示しており、日本の輸出企業や政策当局にとって重要な示唆を含む。
In the global GX context
As the EU advances CBAM, this study provides empirical evidence on how carbon pricing affects global commodity supply chains. The findings highlight allocation-based cost disparities that CBAM could correct, offering insights for policymakers designing border carbon adjustments and for multinational corporations managing carbon costs.

📄 Abstract（原文）
Abstract In the last two decades, rising greenhouse gas (GHG) emissions have driven into global warming. Efforts like expanding renewable energy, produce an increased metal demand, especially copper, which also emits GHGs. Trying to mitigate this, the European Union established the Emissions Trading System (EU-ETS) to regulate and price industrial GHG emissions. This study quantifies the GHG emissions associated with copper production and examines the impact of the EU-ETS and Carbon Border Adjustment Mechanism (CBAM) on copper costs across different temporal and geographical scenarios, concretely across the supply chain of four different countries. A Life Cycle Carbon Footprint assessment was conducted using the Environmentally Extended Multi-Regional Input-Output Analysis with the EXIOBASE database. A sensitivity analysis was also conducted. The results showed that Poland, despite having the lowest emissions, was the most penalized under the EU-ETS, while China, with one of the highest GHG emissions, faced minimal costs. This discrepancy arises as cost from the EU-ETS are based on an allocation principle, which benefits non-EU countries and EU countries that primarily import copper. The study suggests that incorporating copper into the CBAM could help balance emissions and costs by accounting for the GHG emissions of imported products. The sensitivity analysis revealed that countries with higher import levels, such as Spain and Germany, have less control over GHG emission costs by altering their electricity mix. This emphasises the need for coordinated global targets to effectively mitigate emissions.
