SimaPro 7 was the software used for the computation of the
anticipated carbon footprint (Goedkoop et al., 2008). When
allocation is necessary, PAS 2050 specifies the use of (i)
subdivision of unit processes, (ii) system expansion, or (iii)
economic allocation, in order of preference. Additionally,
Table A1 in the Appendix (published as Supplementary
Material online only) gathers the main inventory data for
each of the sections, along with the individual contributions to
global warming.
