It' rarely gets talked about here as this is a mostly tech audience who focus on features, which are important, but Fairphone is more focused on the impact of the manufacture.

"Fair materials" means nothing.
"100% e-waste neutral" is the same as claiming that you are "100% carbon neutral" because you buy carbon "offsets". It's dubious.
There are real positives, though: "100% recycled tin solder paste, 80% recycled steel, 75% post-consumer recycled plastics in the battery frame"
It does not seem like they are buying offsets. Also why would Fair materials mean nothing?
"Fair materials" means nothing in itself and certainly nothing in relation to sustainability.
