Greenhouse gas emission has become a recent global concern for green manufacturing. As the production is one of the main greenhouse gas emission sources, more and more researches have recently begun to pay attention to product low-carbon design. However, the traditional product modeling is easy to produce an obstacle for low-carbon design and lack of an effective integrated modeling approach to support knowledge reuse in product low-carbon design. This paper is devoted to presenting product model integrated with carbon footprint. After the carbon footprint meta-model is proposed, the product model integrated with carbon footprint for low-carbon design is proposed. And the corresponding modeling principles for product model are also discussed in detail. The product model of a magneto-rheological fluid absorber integrated with carbon footprint is used to demonstrate the proposed methodology.
