University of Copenhagen

The University of Copenhagen was founded in 1479 by the Danish king Christian 1, and has today approx. 37,500 students and 9,500 employees. Actory has been established by the University of Copenhagen and Studenterhuset jointly.

Sustainability in focus

The University of Copenhagen has worked with sustainability since 2008. With a strong tradition of research and education in sustainability, it is only natural that UCPH takes the lead and takes responsibility for its own consumption of resources and impact on climate and the environment. UCPH is a city within a city and thus has a large climate and resource imprint. The transition of our society and consumption to sustainability requires a major change and massive efforts, which the University of Copenhagen works on constantly.

Actory creates a framework for students’ commitment to sustainability – supports and motivates their sustainable ideas and work to implement them.
