Please note that the UNFCCC Secretariat does not promote any particular methods or publications.

All Parties to the Convention are required to periodically submit to the Conference of the Parties (COP), in accordance with Article 4, paragraph 1, and Article 12, paragraph 1, of the Convention a report containing information on the following elements:

(a) A national inventory of anthropogenic emissions by sources and removals by sinks of all greenhouse gases (GHGs) not controlled by the Montreal Protocol, to the extent the Party's capacities permit, using comparable methodologies to be promoted and agreed upon by the COP;
(b) A general description of steps taken or envisaged by the Party to implement the Convention;
(c) Any other information that the Party considers relevant to the achievement of the objective of the Convention and suitable for inclusion in its communication, including, if feasible, material relevant for calculations of global emission trends.

Parties not included in Annex I to the Convention (non-Annex I Parties) prepare their national communications following the " Guidelines for the preparation of national communications from Parties not included in Annex I to the Convention " contained in the annex to decision 17/CP.8.

The COP, at its fifteenth session, reconstituted the CGE for a period of three years, from 2010 to 2012 with the objective of improving the process of and preparation of national communications from non-Annex I Parties, by providing technical advice and support to non-Annex I Parties, including those Parties that have not yet completed their initial national communications.

As per its current terms of reference, the CGE is mandated to, inter alia, provide technical assistance to non-Annex I Parties for the regular development of national GHG inventories, vulnerability and adaptation (V&A) assessment, mitigation assessment, research and systematic observation, education, training and public awareness, technology transfer and capacity-building, with a view to improving the accuracy, consistency and transparency of information in their national communications.

In response to the mandate referred to above, the CGE, in its work programme for 2010–2012, agreed to the update of CGE training materials on national communications, including national GHG inventories, V&A assessments and mitigation assessments developed in 2004 and 2005. These updated training materials have been published below for use by national experts involved in the preparation of national communications and other interested stakeholders. These updated training materials should be treated as working documents and hence would benefit from continuous revision and improvement.

The training materials are designed to facilitate the preparation national communications by non-Annex I Parties in accordance with the UNFCCC Guidelines for the preparation of national communications from Parties not included in Annex I to the Convention (decision 17/CP.8). It is in no case intended to replace any of the methodologies or tools referred to or mentioned in its various modules. For further detail and explanation, the reader is therefore always encouraged to go back to the original documents or tools referred to. It is also important to note that some files and links below are from external sites. They are presented merely as an example or illustration. The UNFCCC secretariat is neither responsible for content from external sites nor vouch for the accuracy of the information presented in those sites.

These CGE training materials are also available in French and Spanish.

Further, the CGE also compiled a list of:

• Reference materials on steps to integrate climate change considerations into relevant social, economic and environmental policies and actions (248 kB) ;
• Regional centers of excellence that undertake technical work in the areas of national communications from non-Annex I Parties and also existing activities and programmes, including bilateral, regional and multilateral sources of financial and technical assistance, to facilitate and support the preparation of national communications by non-Annex I Parties (195 kB) .

• Adaptation Policy Framework (APF). The UNDP National Communications Support Programme (NCSP) has developed an Adaptation Policy Framework, which is currently undergoing a review process. The main objective of the framework is to help countries strengthen their capacity for preparing national plans and prioritising adaptations to climate change. According to the NCSP the work may also support preparation of National Communications of non-Annex I Parties. more>>
