The Conference of Parties (COP), by Decision 1/CP.16, decided that developed country Parties should enhance
reporting in national communications (NC) and submit biennial reports (BR) which outline progress in
achieving emission reductions and the provision of financial, technology and capacity-building support to
non-Annex I Parties, building on existing reporting and review guidelines, processes and
It also established a new process, international assessment and review (IAR), under the Subsidiary Body for
Implementation (SBI) for developed country Parties that aims to promote the comparability of efforts among
all developed country Parties with regard to their quantified economy-wide emission limitation and reduction
By decision 2/CP.17, Parties adopted
the detailed guidelines for the preparation of BRs (annex I to decision 2/CP.17) and the modalities and
guidelines for IAR (annex II to decision 2/CP.17). The first rounds of IAR should commence two months
after the submission of the first round of BRs by developed country Parties.
According to the adopted modalities and guidelines, the IAR of BRs from developed country Parties will be
conducted under the SBI in two steps:
- A technical review of BRs, where relevant in conjunction with the review of annual greenhouse gas (GHG)
inventories, and NCs of developed country Parties, which will result in an individual review report for each
developed country Party. The information considered will include all emissions and removals related to
quantified economy-wide emission reduction targets; assumptions, conditions and methodologies related to the
attainment of quantified economy-wide emission reduction target; progress towards the achievement of
quantified economy-wide emission reduction target; and the provision of financial, technological and capacity
building support to developing country Parties.
- A multilateral assessment of developed country Parties’ progress in implementation towards the
achievement of emission reductions and removals related to their quantified economy-wide emission reduction
targets. The multilateral assessment will be conducted on the basis of BRs, the national GHG inventory
(including the national inventory report) and the NC, the technical review report of BR, as well as
supplementary information on the achievement of the Party’s quantified economy-wide emission reduction
target. The multilateral assessment will be conducted under a working group session of the SBI for each
developed country Party, with participation of all Parties. The Party under review may make a brief oral
presentation, followed by oral questions by Parties and responses by the Party under review.
Revision of review guidelines
To improve the rigor, robustness and transparency of the IAR process, the COP in its decision
2/CP.17 decided on a work programme, building on existing reporting and review guidelines, processes and
experiences, covering the revision of guidelines for the review of NCs, including the BRs, annual GHG
inventories and national inventory systems (hereinafter referred to as the review guidelines).
SBSTA 37 adopted the work programme on the revision of the review guidelines (FCCC/SBSTA/2012/5).
According to the work programme on the revision of the review guidelines under the Subsidiary Body for
Scientific and Technological Advice (SBSTA), the review guidelines for NCs and BRs will be adopted by the COP
19 in 2013. The revised review guidelines for national GHG inventories will be adopted by COP 20 in 2014.
These review guidelines will lay a solid foundation for the upcoming IAR commencing in 2014.
SBSTA 38 continued its consideration of the revision of review guidelines. Parties were
invited to submit additional views on the revision of the review guidelines, and these will be consolidated
into the first draft of the review guidelines, to be discussed at the first technical workshop under the work programme during 7-9
October 2013. The workshop summary, together with the revised draft of review guidelines, will provide
further inputs to discussions at SBSTA 39, when the review guidelines for national
communications and biennial reports are to be adopted.
Adoption of the review guidelines
The “Guidelines for the technical review of information reported under the Convention related to
greenhouse gas inventories, biennial reports and national communications by Parties included in Annex I to
the Convention” were adopted by Parties at COP 19 in Warsaw (decision -/CP.19
(132 kB) ). These review guidelines provide a solid foundation for the upcoming technical reviews of NC6 and
BR1 in early 2014 under the new IAR process.
