WebDab - EMEP database

WebDab is the emission database of EMEP (Co-operative programme for monitoring and evaluation of long range transmission of air pollutants in Europe) open to public for interactive use via Internet.


Emissions on Main Pollutants, Heavy Metals, Persistent Organic Pollutants and Particulate Matter are available as totals/sectors and as gridded emissions both for officially reported data and gap-filled emissions. The information on large point sources (LPS) is provided as well. WebDab is regularly updated and includes:


  1. EMISSIONS AS REPORTED BY PARTIES [1980 to (N-2) year]
  2. EMISSIONS USED IN EMEP MODELS [1980, 1985, 1990 to (N-2) year]
  3. ACTIVITY DATA data reported by Parties [1980, 1985, 1990 to (N-2) year]


WebDab contains all emission data officially submitted to the secretariat of the Convention on Long-range Transboundary Air Pollution (LRTAP Convention) by Parties to the Convention. The officially reported emission data should be cited as: EMEP/CEIP 2014 Present state of emission data; http://www.ceip.at/webdab_emepdatabase/reported_emissiondata/ or http://www.ceip.at/status_reporting/2014_submissions/.


Data for modelers


Not reported emissions are gap-filled (EMEP interpolation routine) in order to create complete sectoral gridded emissions for the whole of the EMEP area so that EMEP Centers are able to fulfill their commitments to perform dispersion modeling.


Gap-filled emissions estimated by the CEIP (2006 onwards), the Meteorological Synthesizing Centre - West (MSC-W) (1980, 1985, 1990-2005) and East (MSC-E) (1970, 1975, 1980, 1985, 1990 and 1995) of EMEP are also available.


Gap-filled emissions of Main Pollutants and particulate matter (PM) are generally made by completing and correcting/substituting officially reported data (for details see Technical review report 2009), while for heavy metals (HMs) and persistent organic pollutants (POPs), the estimates presented here do not take officially reported data into account. Data for modelers should be cited as: EMEP/CEIP 2014 Present state of emissions as used in EMEP models; http://www.ceip.at/webdab_emepdatabase/emissions_emepmodels/.

WebDab includes an option for visualizing maps of gridded data and LPS. It is also possible to visualize gridded data and large point source data (LPS) in Google Maps/Earth.


In addition, the EMEP interpolation routine to 0.5x0.5 degrees has been added and can be visualized in the mercator projection. Also test data for 2011 in the new 0.1°x0.1° (long-lat) resolution are now available in WebDab.


Up to 2002 there was an obligation to report emission data for greenhouse gases methane (CH4) and carbon dioxide (CO2) under the LRTAP Convention. This obligation was removed in the process of harmonising emission reporting under the LRTAP Convention with other international bodies requesting emission data. The user is referred to the UNFCCC web database with respect to greenhouse gas emissions.
