Purpose The purpose of this thesis is to develop a theoretical framework for sustainable product design, targeting aesthetic design elements, as part of product development by applying the Ted’s 10 methodology for textile environment and the UN Sustainable Development Goals. Design/Methodology/approach The thesis follows a deductive and inductive multi – method approach. A systematic literature review gives insights into existing literature on product design; the interviews with two experts evaluate the theoretical framework based on the UN Sustainable Development Goals and the implications and applicability of findings in practice. Findings It is found that, in comparison to the UN Sustainable Development Goals, the aesthetic design elements in product design from literature have no clear guidelines to restrict environmentally unsustainable practices/ decisions, apart from EU regulations. The theoretical framework, which is built on these gaps by applying the Ted’s 10 design methodology, shows suggestions concerning the aesthetic design elements, which have the possibility to reduce the need to consume, chemical impact, waste, and energy and water consumption. Two expert interviews validate the theoretical framework and discuss implications and applicability. Originality/value It is stated that product design, especially the aesthetic design elements, have a major impact on the environmental sustainability of the final product. Therefore, decision making regarding these elements have the potential to greatly reduce the environmental impact. Moreover, the analysis of the Ted’s 10 may contribute to the realization of several UN Sustainable Development Goals. It could communicate the positive environmental impact textile and fashion designers and businesses can have when applying the Ted’s 10.
