The entire life cycle of leather production – from the raising of cows to the initial skinning and tanning to the finishing process – has negative environmental impacts.

Leather is often framed as a byproduct of meat and dairy, but considering
the scale of the industry and ubiquity of leather in clothing worldwide,
it’s easy to see why it should be considered as an industry in and of
itself. We know that raising cows for food can be incredibly damaging to the
environment, and when we look more closely at leather production, we can see
that those environmental impacts don’t end with cows’ deaths.
This study was primarily focused on the impact of three post-tanning
processes: retanning, fatliquoring, and dyeing. Retanning is just what it
sounds like: putting tanned leather through the tanning process again.
Fatliquoring involves injecting oil into the leather before it dries such that every fiber is uniformly coated. Dyeing is the process of turning the leather different colors, such as red or blue, using substances that chemically bond to it.
