The School of Business, Economics and Law at the University of Gothenburg has three mandatory sustainability days each year. Day one focuses on Challenges and consists of a full day offering some thirty seminars for students to choose from to introduce them to the SDGs and important sustainability challenges. Day two focuses on Responsibility and consists of a full day group work session mixing our 650-second year students from different programs to work on responsibility projects related to production, consumption. Day three focuses on Solution. We let the student choose between four themes addressing different technical and social solutions and involve representatives from the city, industry, and civil society. For example one theme explores solutions for sustainable urban development.
