In accordance with the strategic materials of Charles University for sustainable development, expert working groups (WG) were established for key areas of Administration and Operations. For the purpose of work efficiency and overlapping of sustainability topics, some key areas of Administration and Operations were merged into one WG (Energy and Construction, Waste and Food services). Thanks to the system of SD Coordinators and their partial involvement, the different WGs share the necessary information, thus ensuring transparency and efficiency in achieving common goals.

The WGs operate in a "Guarantor - Co-facilitator - Member" system, which proved its worth in the University Leaders in SDGs projects (UNILEAD I and II), which brought together 25 Czech public universities and operated from 2022-2023.

Water, greenery and biodiversity WG deals primarily with mapping greenspaces under CU management and their use to support biodiversity.

Members of the PS Water, greenery and biodiversity are:

• Coordinator: Mgr. Lucie Buchbauerová (Faculty of Science)

• Co-creators: RNDr. Petra Horká (Faculty of Science), Ph.D.; Mgr. Pavel Moskala, ThD. (Protestant Theological Faculty); RNDr. Ondřej Sedláček, Ph.D. (Faculty of Science); Doc. Mgr. Michal Žák, Ph.D. (Faculty of Mathematics and Physics)

• Members: Bc. Anna Řezníčková (Central Library); Mgr. Lily Carolin Pokorná Helmbold (CU Point, Rectorate CU)

The WGs, which aim to better coordinate activities at individual faculties and units of the CU, exchange experiences and try to move the CU as a whole towards more sustainable functioning based on specific objectives and activities, are supported by NPO 7.4 Green Skills and Sustainability Support at Universities ("Green Skills at the CU").
