In-depth review of air emission inventories 

Stage 3 review is a technical  in-depth review of selected countries, checking if submitted emission inventories are complete, consistent  over time, properly documented, and accurate. The annual in-depth review aims to be consistent across the Parties and the process should ensure that the same approach is performed every year with the objective to check in detail the inventories of each Party at least once every five years. The process is supported by the European Environment Agency (EEA).  Actual in-depth  review plan was updated after the 6th Joint session of WGE and SB to EMEP (14-17 September 2020) . 

The 3rd joint session of WGE and the Steering Body (SB) to EMEP (Geneva, 11-15 September 2017):  a) welcomed the efforts under the European Union to harmonize the national inventory reviews under the National Emission Ceilings Directive with those under the Convention;  b) recommended that the two review processes be coordinated with respect to priorities, scopes, resources (reviewers) and timelines, to ensure consistency and complementarity and to avoid possible overlaps, duplication of efforts and inconsistent conclusions; recommended to evaluate the coordination efforts upon the completion of the 3-year cycle (2018-2020).

S3 - Country review reports 

A centralised in-depth review of emission inventories (Air Convention and NECD) has been performed annually since 2008. Up to ten Parties are reviewed annually. The expert review team(s) (ERTs) check NFR tables and IIRs submitted by Parties under the Air Convention.  The findings of ERTs are provided to countries for comments. Country reports are sent to countries for comments.  All countries have four weeks to provide feedback to CEIP. ERTs consider comments and update reports if needed. The final country review reports are published as PDF documents (see below).

  • Road Transport with a special focus on the condensable component of PM emissions
  • A follow-up review for the Parties that were reviewed in 2021 (Kazakhstan, Liechtenstein, Monaco and Montenegro)
