Abstract The majority of product environmental footprints for a product are determined at the design stage of its life cycle, especially in conceptual design. However, it is difficult to achieve the solution evaluation for product environmental footprint with unascertained product information in conceptual design. This paper is devoted to conceptual design evaluation for product environmental footprint using unascertained measure model. After the unascertained measure model based on the Unascertained Mathematical Theory is introduced, the evaluation process of solutions in conceptual design for product environmental footprint based on unascertained measure model is discussed in detail. And the product conceptual design for product environmental footprint integrated with unascertained measure model-based evaluation approach is also proposed. The conceptual design of the offshore wind power installation platform is given as an example, which demonstrates that the methodology is helpful to design evaluation in conceptual design for product environmental footprint.
