Various resources and guidance documents are available to assist national emission inventory compilers with development, improvement and reporting of national emission inventories. See also our Links for details of additional guidance materials and tools.
Questions concerning the reporting of official data by countries to the LRTAP Convention should be addressed to CEIP. Specific queries concerning emission inventory techniques and methods may be sent to the leaders of the TFEIP or the co-chairs of the relevant expert panels (see Contacts page).
The EMEP/EEA Guidebook provides methodological guidance on estimating emissions from both anthropogenic and natural emission sources.
The 2014 Emission Reporting Guidelines (ECE/EB.AIR.125), available in English, French or Russian, provide Parties with the formal requirements for the reporting of emissions inventory and projections data under the LRTAP Convention. The Guidelines, together with the additional annexes, are available on the 'Reporting Instructions' webpage of CEIP.
Countries must report emission data under the LRTAP Convention using an official reporting template. The latest versions of the reporting templates are included as Annexes to the 2014 Emission Reporting Guidelines.
Annex I of the reporting template provides the official list of NFR source codes used for reporting air pollutant emissions data.
EU Member States are requested to also use this template when reporting emissions and projections data under the EU's National Emission Ceilings Directive.
This document (ECE/EB.AIR/GE.1/2007/16 - available in English, French or Russian defines the mandate and scope of the annual emission inventory review process conducted annually by CEIP and EEA. The joint review evaluates various quality aspects of the data reported by parties under CLRTAP and under the National Emission Ceilings Directive (2001/81/EC) for EU Member States.
The Air Pollutant Emission Factor Library is a collection of information from various sources such as international organizations' guidebooks, databases, national inventory reports (IIRs), studies, research and data from the literature. You are free to use the information and also invited to enrich the contents with new data. At the moment short interruptions in the service may be caused by the ongoing work of uploading new data. All feedback is warmly welcome through the link on the page.
The mandate and roles of the TFEIP's expert panels is described in this informal document.
