                       Raw carton     For the modelling of the raw carton production four site-specific data
                       production     records of the companies Stora Enso, Assi Dom¨ an, and Korsn¨ as are
                                      consulted. They represent production at three Swedish and one Finnish
                                      location in the year 2002. The data procurement took place in the
                                      framework of an earlier LCA on behalf the FKN IFEU (2004). From the
                                      available data an average value for the raw cardboard production is
                                      formed, used for all examined beverage carton types

                                      logging and transport of wood
                                      The transport of raw carton to the composite production in Germany

                       production     provided by ecoprofiles which were published in the year 2000 by the
                                      European Aluminium Association (EAA), Brussels EAA (2000)
                                      The data record for primary aluminium covers the production of
                                      aluminium on the basis of bauxite extraction, aluminium oxide and
                                      aluminium production (aluminium ingots) including anode produc-
                                      tion and electrolysis. The data are based on collections of the European
                                      Aluminium Association (EAA) in the years 1995 and 1998. A represen-

                                      The data record, according to EAA, was partly updated on the basis of
                                      an survey of member firms in the year 2002. This updated data record
                                      was provided European Aluminium Association (2006) by the EAA for
                                      the use in LCAs. Statements concerning the representativeness of the
                                      updated data are not yet available
                                      The data records for aluminium foils are likewise based on collections
                                      of the Association in the year 1998 for the production of semi-finished
                                      aluminium. Depending on the product group representativeness between
                                      20 and 70% was obtained

                                      processes. The data refer to a period around 1999. They were procured
                                      from a total of 27 polymerisation plants. The plants considered cover an
                                      annual production of 4 480 000 tons. The European total production
                                      in 1999 was approx. 4 790 000 tons. The data thus represent 93.5% of
