Centre on Emission Inventories and Projections

CEIP (the EMEP Centre on Emission Inventories and Projections):


  • collects emissions and projections of acidifying air pollutants, heavy metals, particulate matter and photochemical oxidants from Parties to the LRTAP Convention
  • reviews submitted inventories in order to improve the quality of reported data
  • prepares data sets as input for long-range transport models
  • provides support to the Parties, UNECE secretariat and IC.


CEIP also operates the UNECE/EMEP emission database (WebDab) which contains information on emissions and projections from all Parties to the LRTAP Convention in separate data sets:



CEIP work builds on the emission related work within EMEP (Co-operative programme for monitoring and evaluation of long range transmission of air pollutants in Europe), close cooperation is maintained with the other EMEP centers like CCC, CIAM, MSC-E, and MSC-W. Important collaboration partners are also the UNECE secretariat, the TFEIP, the Austrian Ministry of Environment, the EEA, JRC Ispra and the European commission.


EMEP - the European Monitoring and Evaluation Programme is a scientifically based and policy driven programme under the CLRTAP for international co-operation to solve transboundary air pollution problems.


The Convention on Long-range Transboundary Air Pollution (CLRTAP) has addressed some of the major environmental problems in the UNECE area.


The Convention has been extended by eight protocols and has now 51 Parties [PDF].
