>‘In terms of carbon use, by far the worst material used in the fashion industry, is leather – the amount of land use and CO2 and methane emissions associated with farming cows and then producing leather is crazy.’ One thing we need to think about when it comes to sustainability is use and lifetime of use. Leather has an extremely long lifetime. A well made leather item can last longer than a human life and can be passed on. They've even found still-workable leather in ancient egyptian tombs. I think "vegan" (plastic) leather is a massively bigger problem. (I realize in this article they are discussing a non-plastic material.)
