Definition
What 'Leather' means
Leather production involves raising and slaughtering animals, primarily cows, for their hides. The tanning process often uses chromium and other chemicals that can pollute waterways. While leather is durable, its environmental and animal welfare costs are high, leading many to seek plant-based alternatives.

The longer answer
Leather is a durable material made from the skin or hide of an animal, most commonly cattle, but also sheep, goats, pigs, and exotic species. Consumers encounter leather in shoes, belts, bags, car upholstery, and furniture. It is often marketed as a natural byproduct of the meat industry, though this framing obscures the fact that animal skins are a valuable commodity in their own right.
Leather production involves preserving animal hides through tanning, a process that stabilizes the proteins to prevent decay. The vast majority of leather is chrome-tanned, using chromium salts, which can produce toxic wastewater and sludge. The industry slaughters over a billion animals annually for their skins, with cattle hides representing the largest share. Many hides come from animals raised specifically for leather, particularly in countries like India and China where leather is a primary product, not a byproduct.
For consumers, leather represents a choice with significant ethical and environmental implications. While it is durable and biodegradable under certain conditions, the industry relies on animal farming, which contributes to deforestation, greenhouse gas emissions, and water pollution. Alternatives like plant-based leathers (e.g., from mushrooms, pineapple leaves, or recycled plastic) offer similar aesthetics without animal use, though their environmental footprints vary widely depending on production methods.

In practice
What this means for you
- Check labels for terms like "genuine leather" or "top-grain"—these indicate animal origin, not quality.
- Consider secondhand leather goods to avoid supporting new production while still using durable materials.
- Look for plant-based alternatives labeled as "mushroom leather," "Piñatex," or "apple leather" for animal-free options.
- Ask retailers about their leather sourcing policies; many brands now offer transparent supply chain information.
