NB: Observer organizations include admitted IGOs, admitted NGOs, and United Nations entities. Participants of UNFCCC sessions have to be registered through an online system in order to be able to enter the respective conference's premises. Information on past and future sessions is available here. Information on the registration process can be found on the web pages for admitted NGOs and admitted IGOs and United Nations entities.

Registration of observer organizations' representatives for UNFCCC sessions follows a process with four stages:

1. Admitted observer organizations (i.e. organizations with observer status) nominate all delegates they would like to send to a UNFCCC session;
2. Based on safety and security considerations and the nominations received, the UNFCCC secretariat sets participation quotas, i.e. the observer organizations are informed how many of the nominated representatives they can confirm as delegates;
3. Observer organizations confirm their delegates according to their quota;
4. Confirmed delegates can pick up their conference badge and participate in a UNFCCC conference.

Information on the registration process can be found on the web pages for admitted NGOs and admitted IGOs.

Interventions are the opportunity for observer organizations to address plenary sessions and make their voices heard in the formal negotiation process. The speaking slots are allocated by NGO constituency and limited to 2 minutes each. The statements are available on the submissions portal if provided by the constituency.

Convention bodies often request submissions, i.e. written input, on views and information on various issues under negotiation. The submissions are available here.
