Mission Statement
ChemPubSoc Europe is an organization of 14 European c hemic al soc ieties, founded in the late 1990s as a c onsequenc e of the
amalgamation of many c hemic al journals owned by national c hemic al soc ieties into a number of high-quality European journals.
ChemPubSoc Europe c o-owns and supports these journals inc luding Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemBioChem, ChemPhysChem, ChemMedChem, ChemSusChem, and ChemCatChem whic h are published by Wiley-VCH.
T he partic ipating soc ieties share a c ommitment to sc ientific exc ellenc e, to publishing ethic s, and to the highest standards in public ation, whic h are the basis for the suc c ess of the ChemPubSoc Europe journals.
