1. About the EDGAR project
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.
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)
2. Methodology
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
Ozone precursor gases: Carbon Monoxide (CO), Nitrogen Oxides (NOx),
Non-Methane Volatile Organic Compounds (NMVOC) and Methane
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).
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)
2. Methodology
Calculation of emissions by country and sector:
Technology based emission factor approach (see section 3 for example for road
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.
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)
point sources
- Power plant location
- Production facilities
area sources
line sources
- Agricultural
- Population/ Animal density
-Ship tracking data
- Road network density
3. Example: road transportation
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)
Basic activity data from energy statistics
Technology (passenger car) and EOP information (e.g. EURO 1 vehicles)
3. Example: road transportation
NOx emissions from diesel combustion in road transport in
various world regions (unit Tg NO2)
4. greenhouse gas emissions (Tg CO2 eq.)
Gg CO2-eq. per grid cell
