Abstract: In oder to support low-carbon design of complex equipment, carbon emission links in manufacturing process for complex equipment were analyzed, and a method to describe the carbon emissions was proposed. Through tracking the carbon emissions of each parts in production and describing the processing procedure of basic components, production process oriented basic carbon emission base was constructed. The hiberarchy of product structure was formed by using function-decomposition tree, and carbon emission hierarchical model of complex equipment products was constructed from bottom to top by constructing the structure and drawing the information of carbon emissions layer by layer. This method was applied to a design process. A forging machine low-carbon design platform was built to analyze the model's application. Through hierarchical description of productions carbon emission, each high emission part was located and guidance for low-carbon design was given.

Key words: low-carbon design, carbon footprint, hierarchical model, product design
