Plans for functioning and responsibilities of the new EMEP emissions data centre Party expectations: Plans for functioning and responsibilities of the new EMEP emissions data centre Party expectations: Spain 8 th Joint TFEIP/EIONET meeting Ireland 23 and 24 October 2007

Issues on nomenclatures SNAP Nomenclature: - Coordination of activities for updating SNAP versions keeping Issues on nomenclatures SNAP Nomenclature: - Coordination of activities for updating SNAP versions keeping them in line with methodological advances and new reporting requirements - Maintenance of SNAP correspondence with other nomenclatures: CRF, NFR, RAINS/GAINS, NACE, PRODCOM, … - Repository and clearing-house centre for (SNAP/NFR) emissions inventories/projections oriented to facilitate inter-countries control checks of their (SNAP/NFR) emissions inventories Projections scenarios nomenclature: Harmonization of names and contents

Provide guidance on … - Where to locate and how to estimate emissions of Provide guidance on … - Where to locate and how to estimate emissions of pollutant X (see for reference L&E documents series of US EPA) - Background of the rationale to perform Tier 2 QC checks cross pollutant tests - How to highlight gross errors/missings in inventory activity&pollutant crossings analysis by pollutant: key source categories analysis by activity: what relevant pollutants are missing? - Emission factors evolution taking into account penetration of abatement technologies establishing “defaults” of technologies penetration -Speciation of NMVOC and PAH by full set of relevant SNAP emitting activities -Feedback with the EMEP/CORINAIR GB continuous updating

Liaison with international institutions - With EUROCONTROL for EU-wide and country detailed emissions inventories Liaison with international institutions - With EUROCONTROL for EU-wide and country detailed emissions inventories of air traffic - With IMO for EU-wide and country detailed emissions inventories of maritime traffic - With EUROSTAT/EEA for ready access to country comparable databases of population, GDP, …, and derived environmental indicators - With IEA and EUROSTAT for elaborating (more) environmental oriented energy balances, for example: sectoral split of fuel consumption for electricity in co-generation more detailed information on non-energy use of fuels more sectoral disaggregation of industry final fuel consumption - With EU-wide geographical reference centre Inter-country harmonization of national borders with special reference to EMEP grid

Tracking factors in estimation For PM inventories breakdown by particle size: procedure rationale: 1) Tracking factors in estimation For PM inventories breakdown by particle size: procedure rationale: 1) Providing information, for reference activity categories, on uncontrolled cumulative percentage of particles of size less than: 1 µm, 2. 5 µm, 10 µm, 50 µm 2) Assigning SNAP PM emitting categories to previous referenced activities 3) Estimating total uncontrolled PM emissions and their distribution into diametric intervals 4) Establishing lists of secondary control technologies and their PM sequestering efficiency by diametric intervals 5) Obtaining controlled PM mass emissions by diametric intervals 6) Estimating controlled PM accumulated mass emissions up to upper limits of sizes intervals: 1 µm, 2. 5 µm, 10 µm, 50 µm

Differences (causes of) in inventories 1) Preparing the scene for comparison: “official” vs. “scientific” Differences (causes of) in inventories 1) Preparing the scene for comparison: “official” vs. “scientific” One “official” vs. a number of quality ranked “scientific” 2) For each selected pollutant, presenting “official” vs. “scientific”: National total emissions central estimates (and confidence bands) EMEP gridded emissions central estimates (and confidence bands) 3) Assessing the differences on the basis of their statistical significance 4) Promoting analysesof (causes of) differences via reciprocal access to detailed information on AD, EF and algorithms used by the counterparts: “scientists” vs. “officers” 5) Coordinating efforts for reporting on results of differences analyses 6) Ensuring feedback to improve the “official” and “scientific” methodologies, aiming at convergence on “best estimated inventories”

Spatial & temporal disaggregation Spatial&Temporal: - Harmonise inter-country approaches for selecting good choices of Spatial & temporal disaggregation Spatial&Temporal: - Harmonise inter-country approaches for selecting good choices of surrogate variables, with flows from/to the relevant chapter of EMEP/CORINAIR GB - Inform the countries on relevant national surrogate variables accessible in EU data centres (censuses, CORINE Land Cover, …) Spatial - Harmonise inter-country priorities in “accuracy to the EMEPcell” for point/line/area allocation of emissions sources - Harmonise procedural issues of GIS operations when using different spatial projections. Temporal: - Harmonise inter-country priorities for detail of temporal breakdown according to relevance of emissions sources

Operational - Facilitate information exchange among countries contributing their emissions inventory/projections to the emission Operational - Facilitate information exchange among countries contributing their emissions inventory/projections to the emission centre: - Official information - More detailed information intended for QC checks - Facilitate information exchange with appropriate templates and online procedures for information down/up loading - Further development of REPDAB as a useful QC tool, incorporating relevant Tier 1 (and Tier 2) warnings.
