Is Leather a Sustainable Material

  • by

In the realm of fashion, automotive, and furniture industries, leather has long been celebrated for its durability, texture, and aesthetic appeal. However, in recent years, the sustainability of leather has come under scrutiny, particularly in light of environmental concerns and ethical considerations regarding animal welfare and resource usage. This article examines the sustainability of leather by evaluating its production processes, environmental impact, and exploring the debate over whether is leather a renewable resource.

Understanding Leather Production

Sourcing and Environmental Impact
Leather is primarily derived from the hides of animals, predominantly cattle, which are byproducts of the meat and dairy industries. The argument that leather is a byproduct, however, does not fully address the environmental load of raising animals, which includes significant water consumption, land use, and methane emissions—a potent greenhouse gas.

Tanning and Chemical Use
The transformation of raw hides into leather involves tanning, a process that historically uses various chemicals, some of which are harmful to the environment. Traditional tanning methods, particularly chrome tanning, use heavy metals that can contaminate water sources. Although chrome tanning is employed for approximately 80% of all leather production due to its efficiency and the superior quality of leather it produces, the environmental and health risks associated with hexavalent chromium are well-documented.

Innovations in Leather Production

Vegetable Tanning
An alternative to chrome tanning is vegetable tanning, which uses organic materials such as tree bark and other plant matter. This method is more environmentally friendly and produces leather that can biodegrade more easily. However, vegetable-tanned leather accounts for only a small fraction of the market due to its longer production time and the different aesthetic and textural qualities of the finished product.

Recycled and Upcycled Leather
Efforts to improve leather’s sustainability include using recycled and upcycled leather materials. These practices help reduce waste by repurposing leather scraps and old leather goods into new products. Such initiatives not only extend the lifecycle of the material but also decrease the demand for new raw materials.

Leather and Animal Welfare

Ethical Considerations
The source of leather, primarily from livestock, raises significant ethical questions. The welfare of animals in some leather supply chains is a major concern, with documented cases of mistreatment and poor living conditions. These ethical issues contribute to the debate over leather’s sustainability and influence consumer preferences, particularly among those who advocate for animal rights.

Sustainable Alternatives to Leather

Synthetic and Plant-Based Leathers
As the demand for sustainable alternatives grows, industries are developing synthetic and plant-based leathers from materials such as polyurethane, pineapple leaves (Piñatex), and mushroom mycelium (Mylo). These innovations offer varying degrees of environmental benefits, often requiring fewer resources and causing less pollution during production compared to traditional leather.

Consumer Trends and Market Shifts

Growing Demand for Sustainability
Market research indicates a growing consumer preference for sustainable materials, influencing major brands and designers to explore and adopt eco-friendly alternatives to traditional leather. This shift is not only driven by environmental awareness but also by changing consumer attitudes towards animal products and sustainability.


The question of whether leather is a sustainable material does not have a straightforward answer. While it can be argued that leather utilizes byproducts of other industries and can be durable, its production involves significant environmental and ethical challenges. The move towards more sustainable practices in leather production and the development of alternative materials are positive steps forward. As the market continues to evolve, the sustainability of leather will likely depend on innovations that reduce its environmental footprint and improve the ethics of how it is sourced.
