Leather has several impacts on the environment, the main reasons being:• Carbon footprint of raising cattle (see Environmental impact of meat production)• Use of chemicals in the tanning process (eg chromium, phthalates, nonylphenol ethoxylate soaps, pentachlorophenol and solvents)• Air pollution fr

Leather's natural fibers break down over time. Acid leather is particularly susceptible to red rot, which causes chalking of the surface and changes in consistency. High temperatures and relative humidity can exacerbate red rot damage. Although it is chemically irreversible, treatment can increase h
