Product multi-hierarchy carbon footprint analysis method oriented to low-carbon design

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.
