Please note that the UNFCCC Secretariat does not promote any particular methods or publications.
Parties to the Convention are required to periodically submit to the Conference of the Parties (COP), in
Article 4, paragraph 1, and Article 12, paragraph 1, of the Convention a report
containing information on the following elements:
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;
general description of steps taken or envisaged by the Party to implement the
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.
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.
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.
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.
response to the mandate referred to above, the CGE, in its work programme for
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.
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

training materials are also available in French and

- 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>>
