3. 3 The Emissions Database for Global Atmospheric Research (EDGAR) provides global past and present day anthropogenic emissions of greenhouse gases and air pollutants by country and on spatial grid. Applications: Inventories for policy purposes: - monitoring the progress/compliance in meeting specific emission targets - scenario studies in emissions reduction options (2000-2100 period) Inventories for scientific purposes: - understanding processes that lead to anthropogenic and natural emissions - understanding change in atmospheric composition due to emissions trends EDGARv4 data is used in FP6 and FP7 research projects and in emission datasets prepared for forthcoming IPCC AR5 report. EDGARv4.0 is a project by the European Commissions DG Joint Research Centre with contributions from the Netherlands Environmental Assessment Agency (PBL) 1. About the EDGAR project

4. 4 Geographical coverage: Emissions by sector, year for all world countries, international shipping and aviation Compounds included: Direct greenhouse gases: Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), Hydrofluorocarbons (HFC-23, 32, 125, 134a, 143a, 52a, 227ea, 236fa, 245fa, 365mfc, 43-10-mee), Perfluorocarbons (PFCs: CF4, C2F6, C3F8, c-C4F8, C4F10, C5F12, C6F14, C7F16), Sulfur Hexafluoride (SF6), Nitrogen Trifluoride (NF3) and Sulfuryl Fluoride (SO2F2) Ozone precursor gases: Carbon Monoxide (CO), Nitrogen Oxides (NOx), Non-Methane Volatile Organic Compounds (NMVOC) and Methane (CH4) Acidifying gases: Ammonia (NH3), Nitrogen oxides (NOx) and Sulfur Dioxide (SO2) Primary particulates: Fine Particulate Matter (PM10, PM2.5) and Primary Aerosols: Black Carbon (BC) and Organic Carbon (OC). 2. Methodology

5. 5 Methodology Time series: 1970-2005 (annual), for selected projects (monthly emissions) for commission policy studies 2005-2050 Source categories (main groups): -Energy: Fuel Combustion (IPCC 1A) and Fugitive emissions from fuel (IPCC 1B) - Industrial Processes (non-combustion, IPCC 2) - Product Use (IPCC 3) - Agriculture (including Savanna burning), (IPCC 4) - Land Use Change and Forestry (IPCC 5) - Waste (IPCC 6) - Other anthropogenic sources (fossil fuel fires) (IPCC 7) Spatial allocation:base grid 0.1x0.1 degree grid (also available on 0.5 and 1 degree grid)

6. 6 Calculation of emissions by country and sector: Technology based emission factor approach (see section 3 for example for road transport) x: compound, c: country, s: sector, yr: year, AD: activity data, TECH: technology, EOP: % of technologies that are controlled by end-of-pipe abatement measures, EF: uncontrolled emission factor by sector & technology, RED: reduction % on the uncontrolled EF by the installed abatement measure. 2. Methodology

7. 7 Spatial allocation (xi, yi) = representing the lower left corner of each 0.1 grid cell, AD: activity data (e.g. natural gas in power plant sector), for some maps technology data is gridded (e.g. underground hard coal mines), C: country, yr: year, Indicator (spatial grid, e.g. road density map) line sources point sources area sources - Ship tracking data - Road network density - Power plant location - Production facilities....... - Agricultural fields - Population/ Animal density

8. 8 Formula: EMISSIONTECH = AD x TECH x EFTECH (1-EOP*Eff) (country,year) AD: activity data, consumption of fuels for combustion (TJ diesel in road transport, with data from International Energy Statistics (IEA, DOE, UN) TECH :technology information: share of activity by technology (% of diesel used by passenger cars, trucks, from literature analysis, own studies) EF:uncontrolled emission factor (kg NO2 / TJ diesel, with datafrom IPCC and EEA/EMEP Emission Inventory Guidelines and literature analysis) EOP:share of the specific emission abatement measures (% of diesel passengers equipped with emission regulations (e.g. EURO II, from scientific literature, country reports and own studies) Eff:removal efficiency of abatement measure (% of uncontrolled EF removed, with datafrom IPCC and EEA/EMEP Emission Inventory Guidelines and scientific literature) 3. Example: road transportation

9. 9 Result: NO x emissions from diesel combustion in road transport in various world regions (unit Tg NO 2 ) 3. Example: road transportation
