This section presents the general principles of EDGARv4.0 such as source categories, geographical definitions and the methodology and data for each main source category. Main differences compared to earlier EDGAR datasets are:

• calculation of emissions using a technology based emission factor approach (compared to an average emission factor approach),
• spatial allocation of emissions on 0.1 degree grid cells (compared to 1 degree previously),
• availability of annual emissions data for the period 1970-2005 (previously until 1995 with Fast Track data for 2000).

Other features that are being tested are temporal profiles of emissions and effective emission height attribution. Detailed descriptions of the emission datasets are in preparation.

1.3 Countries

Emissions in EDGARv4.0 are calculated by individual countries using country-specific information. The countries are organized in different world regions for illustration purposes. Emissions of some small countries are presented together with other countries (e.g. Monaco with France) depending on country definition and availability of activity statistics.

2. Calculation of emissions by sector

This section provides information about the methodology applied to calculate emissions that are available for download. Detailed information by main source category can be viewed through the source category table in section 1.2. By clicking on the IPCC code (first column) a factsheet describing the methodology and data for each main source category can be viewed.

2.1 Calculation of emissions by country and sector

Emissions are calculation for the source categories described in section 1.2 and for the countries described in section 1.3 by application of an technology based emission factor calculation. This means that for each considered country-sector combination data is included for the parameters mentioned in the following equation:

Emissions (EM) for a country C are calculated for each compound x on an annual basis (y) and sector wise (for i sectors, multiplying on the one hand the country-specific activity data (AD), quantifying the human activity for each of the i sectors, with the mix of j technologies (TECH) for each sector i, and with their abatement percentage by one of the k end-of-pipe (EOP) measures for each technology j, and on the other hand the country-specific emission factor (EF) for each sector i and technology j with relative reduction (RED) of the uncontrolled emission by installed abatement measure k, as summarized in the following formula:

These parameter data are included in the calculations based on evaluation of scientific literature, inventory guidance, inventory reports, industry reports, dataset documentation or when data was found not available or incomplete own parameter calculations have been made. More information by main source category is provided in section 2.3.

2.2 Spatial allocation

Emissions by country and grid are allocated on a spatial grid to provide gridded emissions dataset for atmospheric modeling. To facilitate application of emissions data in local, regional and global modeling a spatial grid of 0.1 degree has been defined that can be regridded to lower resolutions of 0.5 and 1 degree grid cells.

For this purpose a geographical database has been build using grid maps with 0.1°x0.1° resolution based on data such as location of energy and manufacturing facilities, road networks, shipping routes, human and animal population density and agricultural land use. A screening of the available geographic datasets has been performed for each emission source category with as main criteria coherent spatial coverage and reliability. The input datasets where point, line and area grids at various resolutions and using GIS techniques for conversion, resampling and aggregation the dataset have been included in the EDGAR 0.1 degree resolution grid. Each spatial grid is linked with the reference country grid that is built based data from the "gridded population of the world (GPWv3) country-level and area grids. The country grid present duplicate cells wherever national borders are intersected and in this case the percent value of each country is assigned except for point source that are included as is.

2.3 Methodology and data

An overview of methodology and data per main emission source category is provided through factsheets. By clicking on the IPCC code in the source category table these factsheets can be viewed.

An overview of the main differences between EDGAR v4.0 and EDGAR v3 is provided in the Archived datasets section.
