Admission as an observer organization to the UNFCCC is a one-off process. In accordance with FCCC/CP/1995/7, paragraph 22, organizations, once admitted, are eligible to attend future UNFCCC sessions and do not need to reapply for admission.

Article 7, paragraph 6, of the United Nations Framework Convention on Climate Change provides for the admission of non-governmental organizations to sessions of the Convention bodies as observers. New applicant organizations are formally admitted by the Conference of the Parties following the successful completion of the admission process. Participation at sessions in between the SB sessions and the COP is limited to those organizations that have been admitted or provisionally admitted at previous SB sessions and COPs.

To apply for admission, organizations must submit a set of required documents to the secretariat. The list of required documents is available below under Standard Admission Process.

The deadline for admission is 31 August the year before the admitting COP (e.g. the deadline for admission for COP 22/CMP 12 in 2016 is 31 August 2015). Please refer to the pdf-icon information note on revised deadlines for admission for more details.

Admitted observer organizations should contact the secretariat whenever there is a change in their contact details by completing a Contact Details Form for already admitted organizations (see below) and sending it to Only forms sent electronically are acceptable.

Attending sessions


Non-governmental organizations that have been admitted to the UNFCCC process may attend sessions of the Convention bodies as observers provided that they use the Online Registration System (see below) to nominate and confirm representatives by the set deadlines.

Notification:  The secretariat’s usual practice is to post official notifications or information notes for upcoming sessions on the UNFCCC website three months prior to the start date of the sessions. It is the responsibility of the admitted observer organization to check for notification/information note updates. You can find current information on the Notifications page of the UNFCCC website.

Registration: The UNFCCC Online Registration System (ORS) has been in place for all sessions since 2010. ORS will open upon issuance of the notification/information note which contains the nomination and confirmation deadlines. Designated Contact Points (DCP) of admitted NGOs should use the system to nominate and confirm representatives by the given deadlines. Late nomination and confirmation of representatives after these deadlines will not be accepted as announced in the pdf-icon information note.

For further information on the system, please refer to ORS User Manual.

For technical assistance when using the system, please contact

Attendance: Admission of your organization is not the only way to attend sessions. If your organization is not admitted and you have missed the deadline for admission or if your organization is not eligible for admission, the representatives of your organization might be nominated and confirmed to attend sessions by already-admitted observer organizations who agree for them to be part of their delegation.Visibility will be given to the name of your organization if the nominating organization makes relevant entries in the online registration system when confirming your representatives. The contact details of the admitted NGOs are available here.

Virtual participation: It is also possible to follow the proceedings of UNFCCC sessions via webcast. Please check the Meetings page of the UNFCCC website for the current session and click on webcasts.
