We aim to find solutions to global challenges, including resource scarcity and environmental degradation. These challenges call for scientific knowledge, technology development, policy measures, and action at the local and global level. At the Department of Energy and Environment, we work at the scale of individual components as well as large systems, but our main focus is the interaction between the two. Through our wide-ranging teamwork and partnerships with the private and public sectors, our active participation in public debates, and our responsibilities in the policy process, we are living up to our ambition: Supporting a transition to a sustainable world!
