The ‘Vienna Setting’ is an informal negotiating format established to help delegates reach an agreement during the final stages of a meeting. It involves a relatively small group of delegates, with each major negotiating group (such as the European Union or the Group of 77) represented by only one or two people mandated to make a deal on behalf of their group. It was a format modelled after the final negotiations on the Cartagena Protocol on Biosafety involving spokespersons for the major negotiating groups. Also referred to as the Cartagena Setting.
