Admission to membership is normally instrumented through specific ceremonies of collective signature of the Helsinki Declaration by Mayors or High-Political-Representatives in order to enhance the visibility and political relevance of the network.

To confirm the interest of your city in joining the network, please fill in the membership application and submit it to the GCD Presidency. This document will provide you with more detailed information on how to join the GCD-network and will help GCD to know more about your city, its activities in the Information and Knowledge Society and the issues that your city would like to tackle together with the members of the network.

Once the membership application has been reviewed and accepted by the Steering Committee, the next step would be for mayors to sign the Helsinki Declaration during an official signatory ceremony making her/his city a new member of the network.
