EMEP/CORINAIR Atmospheric EmissionInventory Guidebook Proposal to restructure and update Aphrodite Mourelatou (EEA), Eduard Dame (EC), Kristin Rypdal (EMEP/TFEIP), Jürgen Schneider (EMEP)
What’s the situation with the Guidebook today • Contains most influential set of emission estimation methods for air pollutants in Europe • Essential reference for reporting under both CLRTAP (and its protocols) and the NEC Directive • Some gaps in available information e.g. sector & pollutant combinations • Some other information needs updating • Inconsistencies in method description between chapters • Little guidance on methodological choice and on good practice
Who/What is behind this proposal? • A complete and coherent Guidebook essential for future scientific work, trust among stakeholders and compliance checking of both the NEC Directive and the Convention and its protocols • European Commission asked EEA to prepare a Guidebook update and restructuring plan and indicated its intention to financially support it • EEA prepared such a plan together with the chair of the EMEP SB, the TFEIP chair (representing also the CLRTAP secretariat) and the European Commission • European Commission is about to choose the consultants that will support the execution of the plan • It is this plan that is presented here for discussion • Input from this discussion will be used in steering the consultant’s work
Underlying principles • Guidebook intended main users • Experts responsible for preparing national air pollutant emission inventories to be reported under both CLRTAP (and its protocols) and the NEC Directive • Guidebook objectives • Support compliance with reporting obligations under CLRTAP and NEC • Support inventory improvement process
What would the Guidebook include? • Complete source descriptions • Guidance on good practice aspects such as key source analyses, QA/QC systems, uncertainty management and projections • Guidance on methodological choice (incl. decision trees) • Tier 1 methods for all pollutants from all sources • Tier 2 methods for potential key sources • Tier 3 methods for particularly important methods or methods already included in the Guidebook • Emission factors, both default and technology dependant values for a range of process conditions and abatement technologies that might occur in different countries • Uncertainty estimates for emission factors
How to restructure? • Follow IPCC guidelines as close as possible while respecting particularities of air pollutant inventories • Table of content to follow NFR for source categories • Retain link to SNAP classification as process based sub-categories • General chapter on how to estimate spatially disaggregated emission data in the cross cutting issues section and/or in source category chapters • Separate as far as possible numerical information from the main text (stable information)
Guidebook Emission Factor Database? • Source description • Tier methodology • Good Practice • Uncertainties • … Default EFs and Parameters Additional EFs and Parameters Guidebook components
Why have, or not, an emission factor database? • Reduces data ambiguity and data omissions • More efficient and better data QA/QC • Easier to find what you are looking for • Can require intensive resourcing • May take more time for experts to supply the data / Data suppliers need to be trained • Will the data suppliers choose to use the database?
What role, if any, to an emission factor database • Option A: No database • Option B: Database contains all numerical values of emission factors contained in the Guidebook [Static database of only data in the Guidebook] • Option C: Option B + database contains new data and information approved by TFEIP and expert panels [Living database continually updated with new information]
How to organise the work • The final responsibility for the technical content of the Guidebook lies with the TFEIP • The practical restructuring and update work will be done by the consultants
