Abstract: To support product low-carbon design, the multi-hierarchy carbon footprint analysis method was proposed, and a multi-hierarchy carbon footprint analysis model was established. Through analyzing the influencing factors of product carbon footprint, the static analysis method for product carbon footprint was put forward. By considering the uncertain factors of carbon footprint, the uncertainty analysis model of product carbon footprint was constructed. Based on function-structure mapping, carbon footprint of module units were calculated and allocated. Integrating sensitivity analysis into multi-hierarchy carbon footprint analysis for products, the application of proposed method in design improvement was discussed. A case study of dishwasher was used to illustrate the feasibility and effectiveness of this method.

Key words: carbon footprint, vertical analysis, uncertainty analysis, function-structure mapping, low-carbon design, product design

摘要： 为支持产品低碳设计，提出产品多层次碳足迹分析方法，构建了产品多层次碳足迹分析模型。通过分析产品碳足迹影响因素，提出了产品碳足迹静态分析方法；考虑影响碳足迹的不确定因素，构建了产品碳足迹不确定性分析模型。基于功能结构映射，进行产品碳足迹的结构单元量化与分配。将多层次碳足迹分析方法与敏感性分析相结合，探讨了其在低碳设计改进中的应用。以洗碗机为例，验证了所提方法的可行性和有效性。
