• Reporting Instructions
• Letter to the Parties
• Review of inventories

According to the  workplan for the implementation of the Convention on Long-range Transboundary Air Pollution ( CLRTAP), Parties to the Convention are invited to report on their annual emission and activity data, together with projected national total emissions of main, activity data and updates regarding data for earlier years by 15 February. Informative Inventory Reports (IIRs) are due by 15 March.
  
Parties are kindly invited to:

1. forward their data in standardised format electronically to the EMEP Centre on Emission Inventories and Projections (CEIP) hosted by Umweltbundesamt/Vienna or alternatively upload it on the EIONET Central data depository maintained by EEA and
2. inform the UNECE secretariat of the contents of  their data submission by means of the notification form "EMEP/CLRTAP Emission Inventory Status report 2010" (but without sending the data files to the secretariat). 

CEIP, on behalf of the Convention, will communicate directly with CEIP contact points regarding any queries on Parties submission. Parties are kindly requested to reply to CEIP requests.

IMPORTANT! Reporting templates have been revised! For reporting of emissions and projections Parties should solely use the latest version of the templates "NFR09"  (dated 30.9.2009) posted on the CEIP website. Parties are invited to check the formats trough  RepDab before submitted to CEIP/EEA.

Emission data, projections and activity data that have been reported earlier under the Convention can be found on UNECE/EMEP's web-based emission database WebDab.

Questions or comments regarding the emission reporting can be sent to  CEIP (technical questions on the data submitted) or to the  UNECE secretariat (procedural issues).

A letter with annexes from Mr. Marco Keiner (Director, UNECE, Environment, Housing and Land Management Division) together with an EMEP/CLRTAP Emission inventory notification form 2010 has been sent to the Heads of Delegation of the Executive Body of the Convention to initiate the current reporting round and to provide instructions for reporting. A copy of these documents has been sent by e-mail to the members of the EMEP Steering Body and to the designated emission expert from each Party.

Following the TFEIP Expert Panel on Review meeting May in 2007 in Dessau, a  proposal (ECE/EB.AIR/GE.1/2007/16) was made to the EMEP Steering Body describing an expanded review process (including a Stage III in-depth review). The review of data reported under CLRTAP is performed jointly with those reported under the  National Emissions Ceilings Directive (2001/81/EC) and the process is supported by the  European Environment Agency (EEA).

Methods and procedures for the technical review of air pollutants emission inventories reported under the convention and its protocols (ECE/EB.AIR/GE.1/2007/16), including stage I, II and III (in-depth) reviews, were adopted by the Executive Body at its  twenty-fifth session (available in English, French and Russian).

Based on feedback that the review team of experts have provided, all countries may wish to verify and if necessary correct or update previously submitted data, including time-series gaps.
