Abstract: Carbon emissions calculation can prove the environmental friendliness of product design to a certain degree. To solve the quantitative problem of carbon emissions, a model of input-process-output is established on the typical connections’ characteristics. According to the study of typical connections’ energy consumption, a static calculation method of carbon emissions is proposed for product assembly process. Then, assembly process’ carbon emissions in auxiliary process are calculated by reference to the basic carbon emissions. Taking the air conditioner outdoor set as an example, carbon emissions of the internal connections are calculated, and the results are compared to the simulation results in GaBi, a software used for life cycle assessment. The results show that the carbon emissions in assembly process accounts for a small proportion of total carbon emissions in the whole product life cycle  (0.010 08%). Therefore, when estimating the carbon emissions of the same kind of products, the assembling process can be ignored.

Key words: assembly, carbon emissions, connection characteristics, GaBi
