into impact-reduction targets at the level of the functional unit. The procedure is presented in Sandin et al. ( 2015 ), where it is also applied in the context of the Swedish clothing consumption. Below, the content of Sandin et al. ( 2015 ) is 24 S. Roos et al.

summarised. Further, this section contains an update of the application of the procedure for Swedish clothing consumption compared to the paper and, in addi- tion, the application of the procedure for the US and Chinese clothing consumption. The procedure consists of four steps: (1) identifying the planetary boundaries quanti fi ed in the literature that correspond to the LCA impact category studied in the particular study; (2) interpreting what the identi fi ed planetary boundaries tell us about the need for reducing current global impacts until a chosen point in time (2050, in our case); (3) translating the global impact-reduction targets identi fi ed in step 2 into impact-reduction targets for the speci fi c global market segment of concern (the clothing industry, in our case); and (4) translating the global impact-reduction targets identi fi ed in step 3 to impact-reduction targets per functional unit. In applying the procedure in the context of Swedish clothing consumption, a number of challenges were identi fi ed in each step. In step 1, it was found to be far from a trivial exercise to match the planetary boundaries to LCA impact categories and to translate these to global targets for impact reduction until the year 2050. Table 10 lists the six planetary boundaries that have been quanti fi ed and that were deemed relevant in the context of the Swedish clothing sector, along with related LCA impact categories and the identi fi ed global targets for impact reduction. That impact categories are listed does not mean that the global impact-reduction targets are directly transferable to these impact categories. The speci fi c matching of a target and an impact category depends, for example, on the control variable(s) of the planetary boundary and the characterisation method of the impact category. For the speci fi c LCA context of Roos et al. ( 2015b ), described in Sect. 2 , we found that Table 10 The outcome of steps 1 and 2 of the procedure in Sandin et al.

    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.
