摘要

背景:由于全球变暖是一个至关重要的全球问题,碳税已被引入全球供应链,作为减少温室气体排放的环境法规。每个国家的成本、温室气体排放和碳税价格因经济条件、能源组合和政府政策而异。此外,多个国家签署了自由贸易协定。虽然自由贸易协定带来了经济效益,但也增加了碳泄漏的风险,这增加了全球供应链中的温室气体排放,因为生产基地从一个排放限制更严格的国家迁移到其他排放限制更宽松的国家。方法:本研究提出了一个决策支持的数学模型,以最大限度地减少FTA涉及碳税的总成本。结果:我们的模型确定了供应商、工厂位置以及运输零件和产品的数量,并使用生命周期清单(LCI)数据库估计了成本、FTA、碳税和基于材料的温室气体排放量。通过比较已构建的有自由贸易协定和无自由贸易协定的供应链,并对碳税价格进行敏感性分析,考察了自由贸易协定在全球低碳供应链中的利用情况。结论:我们发现,自由贸易协定不会直接导致碳泄漏,而且对经济地减少温室气体排放是有效的。

Utilization of Free Trade Agreements to Minimize Costs and Carbon Emissions in the Global Supply Chain for Sustainable Logistics
Background: Since global warming is a crucial worldwide issue, carbon tax has been introduced in the global supply chain as an environmental regulation for the reduction of greenhouse gas (GHG) emissions. Costs, GHG emissions, and carbon tax prices differ in each country due to economic conditions, energy mixes, and government policies. Additionally, multiple countries have signed a Free Trade Agreement (FTA). While FTAs result in their economic benefit, they also increase the risk of carbon leakage, which increases GHG emissions in the global supply chain due to relocation production sites from a country with stricter emission constraints to others with laxer ones. Method: This study proposes a mathematical model for decision support to minimize total costs involving carbon taxes with FTAs. Results: Our model determines suppliers, factory locations, and the number of transported parts and products with costs, FTAs, carbon taxes, and material-based GHG emissions estimated using the Life Cycle Inventory (LCI) database. The FTA utilization on the global low-carbon supply chain is examined by comparing the constructed supply chains with and without FTAs, and by conducting sensitivity analysis of carbon tax prices. Conclusions: We found that FTAs would not cause carbon leakage directly and would be effective for reducing GHG emissions economically.
