All must-meet criteria and a number of should-meet criteria are to be met in certain categories in order to receive a certificate. Every event organiser requires an official license holder for Green Meeting certification. The official license holder is responsible for ensuring that the criteria are observed and for presenting proof thereof.
Certification by the Vienna Convention Bureau is free of charge. However, the VCB can only certify events that do not work with an agency or venue that is also a Green Meeting licensee.
