Emissions reporting

The EMEP/EEA air pollutant emission inventory guidebook
The EMEP/EEA air pollutant emission inventory guidebook provides guidance on estimating emissions from both anthropogenic and natural emission sources. It is designed to facilitate reporting of emission inventories by countries to the UNECE Convention on Long-range Transboundary Air Pollution and the EU National Emission Ceilings Directive. It is an essential tool allowing the compilation of comparable and consistent air pollutant emissions inventory data in Europe. Access to high quality air pollutant emissions data is a key element in supporting sound policy-making. It helps to better shape and define environmental priorities, improve air quality modelling, assess compliance with national and international targets and assess the effectiveness of policy interventions in protecting human health and the environment.

Guidelines for reporting emissions and projections data under the Convention on Long-range Transboundary Air Pollution (as adopted by the Executive Body at its forty-second session in December 2022 for application in 2024 and subsequent years)
These revised guidelines assist Parties, through a common approach, in meeting their obligations under the Convention on Long-range Transboundary Air Pollution and its protocols. They support the evaluation of emission reduction strategies and facilitate the technical review of air pollutant emission inventories. They allow for the effective assessment of compliance with emission obligations under the Convention and facilitate the harmonization of emission reporting with reporting under other relevant multilateral environmental agreements and relevant European Community legislation.

Technical Guidance for Parties Making Adjustment Applications and for the Expert Review of Adjustment Applications 
At its thirtieth session (30 April–4 May 2012), the Executive Body adopted decisions 2012/3 and 2012/4 to allow Parties to make adjustments under the Gothenburg Protocol to emission reduction commitments or to inventories for the purposes of comparing total national emissions with them. At its thirty-first session (11–13 December 2012), the Executive Body adopted decision 2012/12 on guidance for such adjustments. The guidance contained in the annex to that decision sets out, in a general way, the principles that Parties should follow in submitting applications for such adjustments.

However, following the first review of applications for adjustments by countries in 2014, it became evident that further, detailed technical guidance was needed. At its thirty-third session (8–11 December 2014), the Executive Body therefore adopted decision 2014/1 on improving the guidance for adjustments. It requested the secretariat to update an informal technical guidance document submitted to its thirty-third session, in accordance with revisions made during the session. The present document contains that technical guidance. It includes not only the main principles of the review process, but also a guide to the step-by-step process that has been established.
