Based on a literature review, those challenges are collected and clustered into nine categories and sub-categories defined for this purpose. Additionally, a research project is analysed. The exhibited challenges such as data availability versus influenceability, a lack of unified sustainability criteria, and decision-making trade-offs underscore the need for refined methodologies and collaboration in sustainability-oriented design. The differently sourced challenges are compared and the new challenges arising from the research project are sorted into the categories. Finally, possible reasons are discussed for why within the project only challenges from four out of nine categories are encountered.en2732-527X2025901910Cambridge University Presshttps://creativecommons.org/licenses/by-nc-nd/4.0/sustainabilityproduct developmentchallengesdesign practicedesign processTechnology::600: TechnologyJournal Articlehttps://doi.org/10.15480/882.1610710.1017/pds.2025.1010410.15480/882.16107Journal Article
