The Commissions share best practices and tools and provide a network of experts for consultation and cooperation. Old and new member cities are encouraged to contact the commissions and join their activities. UBC commissions are encouraged to seek partnerships with other stakeholders and participate actively in implementing regional development strategies, especially the European Strategy for the Baltic Sea Region.
In addition to the Commissions, significant work is carried out in the Working Group on Gender Equality, and Communications Network. The Gender Equality Working Group aims to ensure that gender equality perspective is mainstreamed into the work of all the commissions of UBC and the UBC member cities. The Communications Network aims to improve communication between UBC and its member cities, to share best practices and tools and to provide a network of experts for consultation and cooperation.
