This paper doesn’t outline how to measure and report social sustainability. This task has already been undertaken by the author and presented elsewhere (see Kimmet and Wikstrom 2005). The much less ambitious objective of shoring up the case for such measurement frameworks is all that’s attempted here. Arguably though, this is at least as important as how to do it, given that many real estate investors will want to evaluate potential investments in their own way once it is clearly understood what social sustainability is, and why it should be taken seriously. .
