8 For the purpose of these guidelines for national systems, the inventory development process encompasses inventory planning, preparation and management.

7 National GHG inventories are referred to simply as inventories in these guidelines for the sake of brevity.

Inventory preparation As part of its inventory preparation, each Party included in Annex I shall

However, the supplementary information is not required until the start of the first commitment period in 2008, and thus will not affect activities in 2006 2007.

The Subsidiary Body for Implementation (SBI) requested the secretariat to prepare a note on streamlining these review processes, in order to avoid possible duplication of effort and ensure efficient use of available resources.

Part II Review of annual inventories

All procedures are now in place however, the secretariat has not yet received any confidential inventory information from a Party.

The secretariat selects experts for these teams from nominations by Parties to the roster of experts. Invitations to participate in the review are copied to the national focal point.

The full text of the conclusions of the lead reviewers' meeting is available on the UNFCCC web site.2 Inventory review training Decision 12 CP.

List of inventory review resources relevant for the calculation of adjustments

The inventory review resources listed in appendix I provide recommended approaches and tools for clustering inventory data.

The Meeting also recalled its agreement to discuss further the establishment of such inventories at its twenty fifth session under a separate agenda item.

All 36 inventory review reports were completed on time, or within one week of the due dates established in the inventory review guidelines.

The Meeting noted various options for creating inventories, including the experience of some entities with maintaining such inventories.

National systems should be designed and operated to support compliance with Kyoto Protocol commitments related to the estimation of anthropogenic GHG emissions by sources and removals by sinks.

Table 1 Inventory review experts in 2004 by nominating Party Other inventory review procedures In accordance with decision 12 CP.9 the secretariat developed procedures to implement the code of practice for the treatment of confidential information during the inventory review.

Meeting of inventory lead reviewers Under the UNFCCC review guidelines (FCCC CP 2002 8), expert teams are to be lead by two experts with substantial inventory review experience.

However, the inventory data have 1990 and 1994 as base years.

Recommended international data sources (for activity data, drivers, and emission factors and other estimation parameters)

Recommended approaches and tools for clustering of inventory data

The purpose of the review of annual inventories of Parties included in Annex I is

The current inventory reporting guidelines are contained in document FCCC SBSTA 2004 8.

The common reporting format (CRF) is an integral part of the national inventory submission.

All of the experts participating in the 2004 inventory reviews have signed this agreement.

The secretariat extended 39 invitations to national focal points for inventory experts.

The use of drivers or approaches and tools for clustering of inventory data other than those recommended in the inventory review resources listed in appendix I should be explained and justified.

Requests that lead reviewers, as defined in paragraphs 36 42 of the guidelines for review under Article 8 of the Kyoto Protocol (decision 23 CP.7), collectively consider and make recommendations on

If the calculation of an adjustment requires the use or replacement of activity data, e.g. either as input to the IPCC tier 1 default methodology or because the activity data are the cause of the adjustment, and if no national data are available, expert review teams should use, in order of preference

8 In these cases, reallocation is recommended to the Party as part of the review of annual inventories under Article 8.

This appendix lists inventory review resources relevant for the calculation of adjustments using the adjustment methods and approaches described in the technical guidance.

The inclusion in the inventory review resources listed in appendix I of drivers and approaches and tools for clustering of inventory data should be subject to guidance by lead reviewers in accordance with the provisions of appendix I.

Inventory submissions from Parties, when put together in an information system, are a valuable resource that will grow in value with time.

The next biennium will see the full operationalization of activities to support implementation of the Kyoto Protocol inventories, reviews, registries, mechanisms and compliance.

The secretariat extended 41 invitations to national focal points for inventory experts to participate in this training.

Preparation of reliable country inspection lists

13 If the reallocation will not have such effects, reallocation is recommended to the Party as part of the review of annual inventories under Article 8.

As of 2004 only experts who have successfully passed the examination for the training programme can participate in an inventory review.

As a result, experts from Denmark, Egypt, Iceland and South Africa are expected to participate in an inventory review in 2005.

Lead reviewers also discussed technical issues that have arisen in the review of GHG inventories, including review of a GHG inventory that is a compiled from different national inventories, and the assessment of the choice of methods used in the preparation of an inventory estimate.

Designate a single national entity with overall responsibility for the national inventory Make available the postal and electronic addresses of the national entity responsible for the inventory Define and allocate specific responsibilities in the inventory development process, including those related to choice of methods, data collection, particularly activity data and emission factors from statistical services and other entities, processing and archiving, and QC and QA.

Scope of the review

If national data as indicated in paragraph 2528 above are not available or are not deemed suitable for the respective adjustment case, expert review teams should select data from the recommended international data sources included in the inventory review resources listed in appendix I.

The information contained in the inventory review resources listed here will be maintained by the UNFCCC secretariat and made available to expert review teams by electronic means.

Decision 12 CP.9 further requires that all members of expert review teams must sign an agreement for expert review services, which specifies the responsibilities, expected time commitment, and appropriate conduct for expert review team members, in particular with respect to the protection of confidential inventory information.
