The purpose of the present degree project was to investigate the possibilities of assessing social sustainability and, on this basis, to carry out an equality analysis of wood as a construction material. The latter part of the purpose was met by carrying out social life cycle assessments focusing on gender equality: one for wood as anengineering material and one for house with wooden frame. The result was presented as a gender index which indicated the proportion of the work carried out by women. To gain more knowledge about wood as an engineering material a complete social life cycle assessment is necessary. A complete social life cycle analysis should not be reduced to a single measurement number by merging different effect categories of social sustainability. The conclusion in the report was that such an analysis is better to present in so-called polar diagrams where each individual impact category can be distinguished, but not necessarily all indicators. The method used to assess gender equality can be used to assess other impact categories.
