"The project ThüLeNa focuses on integrating sustainability topics into engineering studies across multiple universities in the German state of Thuringia. Asynchronous, digital modules offered as electives are complementing the pre-existing curricula, thus allowing for a state-wide exchange of knowledge, transdisciplinarity in engineering disciplines, and a greater selection of possible subject matter for engineering students. In addition, completing modules amounting to 15 ECTS allows students to obtain a certificate that signals a deepened engagement with sustainability from an engineering perspective and that will enhance future employment opportunities. ThüLeNa may thus provide a customizable blueprint for integrating sustainable engineering and energy topics as a micro credential into various engineering disciplines within the European university system and in doing so prepare a new generation of engineers for current and future sustainability challenges."
