Nowadays, industrial products, particularly household appliances, are strongly related to environmental issues. Due to high levels of uncertainty regarding design embodiments at the early design phase, new methods and tools are essential to provide designers a basis to determine the degree of sustainability of a given product. The paper aims to integrate ecodesign activities within the traditional flow of the product design process through the development of an integrated software platform which supports the decision-making task for product sustainability in the early phase of product design.
