The construction of this database had not been possible without the funding and cooperation of many individuals and organizations. In particular, we would like to mention NRP-MLK and the Dutch Ministry of the Environment (VROM) for funding and GEIA and dr. J.A. Logan at Harvard University for providing a population distribution on 1x1 degree, which is pivotal information to construct the gridded emissions. In addition, notwithstanding the help of persons not mentioned here, we would like to mention in particular the assistance and cooperation of the following persons and organizations, which is greatfully acknowledged: 

• Dr. Robert J. Andres and dr. Greg Marland of Oak Ridge National Laboratory, for providing information on CO₂ emission factors for fossil fuel combustion.
• Dr. Carmen M. Benkovitz and Mr. M. Altaf Mubaraki at Brookhaven National Laboratory, for their help in evaluating emission factors for SO₂ from the production of non-ferro metals, for locating many coal mines in the USA, and for providing data on oil and gas production in the USA and on the NAPAP inventories.
• Dr. Frank Carnovale of Coffey Partners Int. PTY Ltd, for providing Australian emission inventory data on NMVOC.
• The Conseil Europien des Federations de l'Industrie Chimique (CEFIC) and the Japanese Association for the Hygiene of Chlorinated Solvents (JAHCS), for providing overviews of solvent use for important parts of the world.
• Prof.dr. David O. Hall and dr. Frank Rosillo-Calle, of the Biomass User's Network's Information and Skills Centre at King's College (UK) for their cooperation, information and advice on biofuel consumption data.
• Dr. Wei Min Hao at the Intermountain Fire Science Laboratory, for providing the biomass burning maps.
• The IEA for providing additional information on conversion factors for the energy statistics.
• Members of IPCC Expert Groups, for their valuable information of several aspects Mrs. Janice L.W. Jolly of the International Copper Study Group at Lisbon, for providing information on global copper production facilities.
• Dr. Niels Kilde at RISO, for providing information on international shipping.
• Dr. G.J.M. Linssen and drs. Thea van Dijk of the Dutch Ministry of Economic Affairs, for providing information on global lead and zinc production facilities.
• Dr. Jennifer A. Logan at Harvard University, for providing the 1x1 degree population distribution map, which has been a pivotal element in the construction of the grid-based emission inventories dr. Archie McCulloch at ICI Chemicals & Polymers Ltd, for his information and advice on N2O from global adipic and nitric acid production and on the distribution of halocarbon consumption per country.
• Dr. Elaine Matthews at NASA-GISS, for providing preliminary maps of global production of fossil fuels.
• Dr. P.M. Midgley of M&D Consulting, for stimulating discussions and contributions on chlorinated solvent use data.
• Mr. Kari Nevalainen at the UN-ECE Statistical Division, for providing global data through the Information Environmental Data Service (IEDS).
• Dr. Cindy Nevison for providing the map for N2O from oceans.
• Mr. John Stork of NOVEM (NL), for providing documentation on the location of global coal mining activities.
• Dr. Zissis Samaras at the Aristotle University, Thessaloniki (GRC), for providing his global inventory of emissions from road transport.

And last but not least we wish to mention the cooperation with the various Working Groups of the Global Emissions Inventory Activity (GEIA), which is convened by dr. Thomas E. Graedel of AT&T. In particular we would like acknowledge NASA and dr. Alex Guenther of NCAR for providing, through the FTP site of the GEIA data distribution centre located at the National Center for Atmospheric Research (NCAR), Version 1 of the GEIA aircraft emissions and natural NMVOC emissions data sets, respectively.

Finally, for Version 1.0, an interim version especially developed for environmental assessment of aircraft emissions at 5x5, we particularly thank the following persons for their valuable contribution: 

• Dr. Charles T. Walker at AEA, Technology, Culham (UK) for the use of the WSL air traffic database.
• Dr. Peter J. Newton of the British Department of Trade and Industry (DTI), for computer runs with the DTI air traffic model.
• Dr. Roger M. Gardner of the British Department of Transport, for his advice on gridded aircraft emissions inventories.
• Dr. Jean-Francois Muller of the Belgian Institute for Space Aeronomy (OMA) for providing the gridded inventory of surface source emissions and drs. Rene Baart of PSB, who developed the EDGAR software to handle the emission inventories on 5x5 degree resolution.
