In a way that mirrors the shift to organic cotton, the sector that produces leather is also plotting a new trajectory towards keeping leather sustainable. The leather processing sector is pivoting towards more sustainable methods as the world becomes increasingly conscious of environmental and ethical implications.

Ethically sourced leather, often referred to as the name suggests ‘sustainable leather alternatives,’ is crafted using eco-friendly tanning processes, efficient use of resources, and waste reduction and management strategies. This approach not only mitigates its environmental impact but also conserves resources, promotes animal welfare, and aligns with consumer demand for more responsible and ethical products.

Are Animals Killed to Make Leather?

Contrary to widespread perception, animals are not killed to produce leather. In fact, 99% of the world’s leather produced comes from animals raised for food, making leather a by-product of the meat industry. This process of using leftover animal hides for leather is part of a highly sustainable process.

According to industry sources, the hide of the animal accounts for slightly above 1% of the entire value of the animal. It would not be practical to kill an animal just to produce a product that accounts for such a small percentage of the animal’s value. As long as consumers eat meat, there will be leftover hides. These hides can either be wasted and thrown into a landfill, or they can be used to make beautiful products such as leather car seats, furniture, shoes, handbags, purses, wallets, and so much more!

Modern leather manufacturing actually recycles more than 270 million cow hides per year, saving landfills from over 7.5 million tons of waste annually! Leather honors the life of the animal by ensuring the hide does not go to waste.”

What is Sustainable Leather?

Ethically sourced sustainable leather emerges from environmentally friendly tanning processes, efficient use of resources, and effective management of leather waste. The potential to lessen the environmental impact of leather production, conserve resources, improve animal welfare, and deliver sustainable and ethical products to consumers underscores the importance of sustainability in the leather industry.

A range of sustainable alternatives to conventional leather, including leather substitutes with unique production processes, benefits, and challenges, have surfaced. These alternatives not only reduce the industry’s dependence on animal hides but also offer the potential for more “environmentally friendly” leather production.

For instance, pineapple leather, also known as Piñatex, is made from pineapple leaf fibers, offering an animal-free and low environmental impact alternative. Mylo mushroom leather, derived from mycelium, the root structure of mushrooms, is another innovative alternative that is biodegradable and doesn’t require the extensive land use associated with traditional leather. Desserto, a leather alternative made from cactus, is not only sustainable but also highly durable.

Additionally, lab-grown leather, produced through biofabrication processes, is emerging as a promising alternative, though it’s still in the early stages of development.

These alternatives provide a plant-based option for those seeking to make an “environmentally friendly” choice. Comparative life cycle analyses (LCA) determining the most sustainable material amongst traditional leather, faux leather, and plant-based alternatives have not been completed to date. However, global organizations such as Textile Exchange and the Leather Working Group (LWG) have launched LCA projects to investigate such comparisons.

While these alternatives provide promising eco-friendly options, comprehensive life cycle analyses comparing their sustainability impacts to traditional leather manufacturing are still limited. Initial research indicates some plant-based leathers may have higher greenhouse gas emissions due to land usage requirements. More data through industrial-scale studies is needed to conclusively determine the optimal materials and processes from a sustainability perspective.
