The committee is supported by a secretariat that handles day-to-day operations. The secretariat staff members have a sound professional background in various sustainability-related disciplines as well as experience in science and project management.
The secretariat is responsible for all operational tasks, both internally and externally. This includes supporting the committee in implementing its strategy, organizing events and meetings, press and public relations work via various media, networking and supporting the national scientific community as well as building and maintaining contact with strategic partners in Germany and partners on the international level.
The DKN secretariat thus acts as interface, platform, national contact point and coordination office. In its current third term of office (2019-2022), it is located at the Climate Service Center Germany (GERICS) in Hamburg, which is headed by DKN Chair Prof. Dr. Daniela Jacob. Dr. Sebastian Sonntag, DKN Executive Director, heads the secretariat and is an ex-officio member of the committee.
