If you believe that today’s post is about little rodents that behave equitably, then you have most probably not heard about NagerIT’s project to build fair computer mice. (Although the German term “nager” translates literally as “rodent”.) NagerIT took supply chain transparency to an extreme, disclosing the entire supply chain of their Fair Mouse (pdf) on their website, thereby highlighting suppliers with unknown details on working conditions. The Fair Mouse project reveals how difficult it can be to produce a product that is 100% fair: NagerIT admit that they stay with “the problem of the mining of the metals (except solder tin) and the assembly of the remaining components, which [they] still can not obtain from alternative (fair) suppliers”. However, a good start has already been made. The story of the Fair Mouse is, of course, a little like the story of the Fairphone, recently presented here by its founder.
