During INC sessions, negotiations took place in various formats. • Contact groups: Negotiations based on specific articles of the treaty text. All states with delegations participate and can raise their voice. This format was open to observers but with no possibility for interventions. Usually multiple contact groups occurred simultaneously. • Regional meetings: Closed coordination meetings to discuss and align positions among a certain subgroup of member states, for example based on
UN Regional Groups or other groups such as the High Ambition Coalition. Few regional meetings permitted the presence of observers, at least partially. • Informals: Closed negotiations in an informal framework but organizational aspects (such as duration and room arrangements) might still facilitated by the INC Secretariat. Informal-informals (also known as infinfs) are more casual negotiation settings. • Plenaries: Official assembly by all negotiating member states. They are used to open and close INC sessions and to report on progress of negotiations. Plenaries are open to observers and are also broadcast and recorded. Observers united as alliances might be able to contribute short interventions if the INC Secretariat permits. A total of 29 plenaries were held during all six negotiation sessions. Besides these formal formats of negotiations delegates and observers were able to participate in side events, press conferences and so on. == Content ==
