Admitted non-governmental organizations



This webpage provides information for non-governmental organizations (NGOs) that have observer status, i.e. that have been admitted by the Conference of the Parties as observers to the UNFCCC.

If your organization is not admitted, information on the admission process can be found here.

List of admitted NGOs

Registering participants for sessions



Admitted NGOs may be represented at sessions of the Convention bodies as observers provided that they use the Online Registration System (ORS) to nominate and confirm representatives by the set deadlines.

Notification: The secretariat’s usual practice is to post official information for upcoming sessions on the UNFCCC website three months prior to the start date of the sessions. You can find current information on the Notifications page of the UNFCCC website.

Registration: 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.

For further information and guidance on the nominations and confirmation process and using the system, please refer to the pdf-icon ORS User Manual.

For technical assistance when using the system, please contact

For other issues relating to registration, please contact the secretariat through the communication field within the ORS.

Constituencies in the UNFCCC are self-organized loose group of NGOs with diverse but broadly clustered interests. Constituency Focal Points provide a conduit for the exchange of official information between their constituents and the secretariat. Participation in a particular constituency is neither official nor is it binding. However, there are potential benefits in belonging to one of the constituencies such as input to joint statements/interventions; office space at COPs; timely information through constituency daily meetings; access to bilateral meetings with officials; tickets for limited access meetings, etc. Please see the following document for more details:
Constituencies and you (version as of May 2014)  pdf-icon English (93 kB) pdf-icon Español (28 kB)  pdf-icon Français (83 kB)

The constituencies mirror the 9 Major Groups, established in the pdf-icon Agenda 21 and re-confirmed in the outcomes of the Rio+20 summit (A/RES/66/288 - The future we want).
BINGO Business and industry NGOs
ENGO Environmental NGOs
Farmers* Farmers and agricultural NGOs
IPO Indigenous peoples organizations
LGMA Local government and municipal authorities
RINGO Research and independent NGOs
TUNGO Trade union NGOs
WGC Women and gender constituency

*Provisional Constituency - Based on their request, the above group is recognized as a constituency on a provisional basis pending a final decision of their status.

If your organization already belongs to a constituency is indicated on the list of admitted NGOs.

Since 2016 the UNFCCC secretariat also recognizes the following groups as informal NGO groups:

  • Faith Based Organizations (FBOs);
  • Education and Capacity Building and Outreach NGOs (ECONGO);
  • Parliamentarians.

These informal NGO groups do not enjoy all privileges of an official constituency, but their morning coordination meetings can be announced on CCTV and in the Daily Programme (DP) and they receive a certain amount of tickets to limited access meetings such as opening ceremonies.

Participating in workshops and intersessional meetings

Workshops and meetings are mandated by the COP or subsidiary bodies as vehicles for informal advice and inputs from experts, information sharing among delegates, and promoting consensus-building on strategies outside the political negotiations. They are normally small, with restricted numbers of participants to allow them to function effectively and to fulfil the task assigned to them. The chairs of the subsidiary bodies, advised by the workshop/meeting chairs, have key roles in deciding the format of, and participation at, a workshop/meeting, including deciding whether and how many observers will be invited. This number will be determined by the nature of the workshop/meeting and the resources available, and will take into account the level of interest among the observer organizations, with the ultimate aim of allowing an effective working atmosphere with an appropriate balance of participants.

Participation of non-governmental organizations is facilitated through the constituencies (see above), so as to aim for a balanced representation of the admitted non-governmental organizations. The secretariat contacts constituency focal points for them to nominate constituency representatives based on the expertise required for respective workshops/meetings. Constituency members interested in, and suitably qualified in the matter of, a particular workshop/meeting, should contact the respective constituency focal point. Please note that selection of representatives will be at the discretion of the relevant constituencies and the secretariat has no involvement or influence on this.

  • Related documentation regarding observer participation at workshops is accessible through MAS Observers.
