5 Reasons Why Leather Car Interiors Are the Sustainable Choice

Leather is upcycled from a waste product.

Leather is a by-product of the meat and dairy industry, confirmed by the World Wildlife Federation (WWF) in 2022. The farmer receives just 1%-2% of the total value of the cattle from their hides, which indicates that cattle are not raised to make leather, it wouldn’t be financially viable. Report by One 4 Leather.

If animal hides weren’t used to make leather, they would be sent to landfills where they would rot and emit CO2. If the automotive industry stopped using leather in cars, an extra 644 million kg of CO2e would be emitted annually, but if they increased the use of leather in cars by just 10%, it would prevent 3.5 million hides from landfills, that’s a saving of over 64 million kg of CO2e.

Using leather in cars prevents harmful virgin materials from being created

Whilst the current demand for meat and dairy continues, there will always be cattle hides that we can either use or discard. Using leather, an upcycled natural by-product, in a car interior is better for the planet than manufacturing a new leather alternative material.

Synthetic alternatives to traditional leather, often labelled as ‘Vegan Leather,’ primarily consist of man-made materials, typically comprising approximately 80-90% polyurethane (PU) or polyvinyl chloride (PVC) for binding. Some manufacturers of these alternatives engage in greenwashing, some also claiming to use recycled PET (rPET) and presenting it as environmentally friendly. The reality of this is new virgin plastic needs to be produced to replace this to make new bottles, packaging, etc. 1, resulting in having to extract more fossil fuels from the earth, producing large amounts of CO2e that damage the planet. Why create a new, harmful product when a more sustainable, natural alternative already exists?

Leather is part of the circular economy

Leather is part of the circular economy, where every part of the cow is used, and nothing is wasted. The hides are upcycled into leather, a natural material with a biogenic carbon count of over 80%. Upon reaching the end of its life, it can be composted to enrich the soil. This, in turn, nurtures the growth of grass, providing sustenance for the very cows that initiate this regenerative cycle all over again.


Compare this to most new plastic and fossil-fuel-based leather alternatives that are linear. Commonly, a plant-based material, like mushrooms or pineapple husks, is mixed with fossil fuels like PU or PVC (in the region of 80 – 90% of the total) to create a composite material. There is no simple or cost-effective way to recycle these products, so they end up in landfill, a “Take, Make, Waste” approach with a tangible impact on the planet, but we are led to believe they are more sustainable.

Leather has a long lifespan

Fast fashion has become ever popular in society, but more and more people understand that ‘buy once, buy well’ is a more sustainable approach and better for the planet.

Automotive leather, which is simple and cheap to maintain, will last decades and still look and perform great, and have a lower environmental cost per use impact across its lifetime. Most ‘vegan leather’, on the other hand, is likely to have a much shorter lifespan before it cracks, peels and needs replacing, usually with PU/PVC covers made from harmful petrochemical-based products.

There have been high-profile cases in the media of car owners reporting significant issues with ‘vegan leather interiors’, which bubble and blister after short periods. These materials do not have the performance, durability and lifespan of genuine leather and will likely need replacing during the expected lifespan of the car.

Leather reduces impact on the planet

Ocean plastic pollution has highlighted just how important it is that materials can degrade back into the natural environment.

Leather is naturally biodegradable. A rawhide will decompose very quickly, and a tanned hide will take between 10 to 50 years, depending on how it is processed. When you compare this to ‘vegan leather’, it’s a fraction of the time. With no current viable option but landfill, these plastic and fossil-fuel-based synthetics will still be around in 500 – 1,000 years, emitting dangerous gases and microplastics that are harmful to the environment and human health.

In recent years, automotive tanneries have invested heavily in ensuring leather is produced in a more sustainable and environmentally friendly way reducing the carbon impact. Current developments in sustainable tanning and finishing are reducing the time it takes to biodegrade or turn into compost, further lessening the impact on the planet.
