each can be subdivided into subcategories. The groups that each garment represents were selected based on the following prioritisation of criteria: 1. Knitted or woven construction, 2. Fibre type (cotton, synthetics, regenerated or denim), 3. Similarity, in terms of function of the garment, use pattern, etc. Table 3 shows for each modelled garment how large part of the Swedish clothing consumption was assumed to be represented by each garment. The industry sector approach enabled national statistics on imports, exports and production to be used as a basis for the assumptions about the length of the garment service lives. Thus, the garment service lives were not based on hypothetical technical service lives, but on the actual user behaviour as indicated by national statistics [combined with some complementary assumptions, see Roos et al. ( 2015b ) for more details]. This means that the assumed number of uses per garment re fl ects average behaviour by Swedes. It should be noted that the number of uses in this study does not correspond to the number of washing cycles, as the number of washing cycles per use was also based on data on actual consumer behaviour, collected by means of consumer surveys (Granello et al. 2015 ; Gwozdz et al. 2013 ). 2.1.3 Results This section shows selected results, focusing on climate impact calculated with the GWP100 method (IPCC 2013 ). For more results, see Roos et al. ( 2015b ). The study of the environmental impact per use of each of the fi ve garments (the functional units of the study) allows for studying micro-level aspects, such as the environ- mental signi fi cance of different life cycle phases for different garments. The assessment of the environmental impact of the total Swedish clothing sector is a study of macro-level aspects, such as the relative importance of different garments and the potential of different measures for impact reduction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
