When the optional CDIO Standard for Sustainable Development was introduced in 2020, the CDIO community was encouraged “to document the work and share their experiences, in particular reflecting on the usefulness of the new standards for future refinement and development”. This paper is a response to that call, providing insights in how this optional Standard has been used for evaluating and enhancing the status of sustainability in the Civil Engineering and Urban Management program and Electrical Engineering program at the KTH Royal Institute of Technology. Details are shared on how sustainability is integrated in the programs, and opportunities and barriers for enhancing the status of sustainability in the two programs, and in engineering education in general, are discussed. The paper concludes that the CDIO Standard for Sustainable Development provides a framework and terminology for dialogue and collaboration, within as well as between programs, that can be used for driving change, from an add-on approach, through integration approaches, towards transformative approaches to sustainability in engineering education.
