This overview guide on the United Nations Framework Convention on Climate Change (UNFCCC) highlights the different types of documents relevant to the process. The paper notes that the UNFCCC comprises of country groups, UN regional groups and the bureau. Other conference participants include NGOs, indigenous peoples’ groups, trade unions, observers, representatives of UN agencies and other intergovernmental organisations and the media. The UNFCCC negotiating bodies include:

Conference of the Parties to the UNFCCC (COP)
Conference of the Parties serving as the Meeting of the Parties to the Kyoto Protocol (CMP)
Subsidiary Body for Scientific and Technological Advice (SBSTA )
Subsidiary Body for Implementation (SBI) 
Ad Hoc Working Groups.

The guide states that the negotiation process may vary depending on the body and meeting, because negotiators follow a formal set of rules. For example, in COP and CMP plenary meetings country groups and countries make opening statements, which set the general priorities for the negotiations. The paper explains that country statements are expected to be given in behalf of a country group or groups and this regional support should be mentioned in the beginning of the statement. Statements opposed to the position of the group that the country belongs to are considered inappropriate. The guide concludes that wording plays a key role in the process. Negotiations are mainly conducted in English and words can have a different meaning in the context of the UNFCCC; sometimes changing one word can alter the meaning of the entire text.
