“纯素皮革”的环保性和可持续性，不如品牌声称的那么高

In a high-end fashion store or luxury car showroom, the term “vegan leather” sends a strong message of quality. For many shoppers, it promises the look and feel of real leather without using animal skins. As brands move away from animal leather, “vegan” has come to suggest something that is both kinder to animals and better for the planet.

However, the reality is more complicated. While these materials remove animal products, they often replace one environmental problem with another. Vegan leather is not one material, but a broad label that covers everything from plastic coatings to plant-based surfaces, which is why regulators are starting to question vague green claims.

The appeal of leather alternatives is easy to understand. Concerns about animal welfare, climate change and deforestation have pushed shoppers and brands towards options that seem more responsible.

As a result, “vegan leather” is often seen as the better choice – even though how long it lasts, and where it ends up, is rarely questioned.

The rise of synthetic hide

For decades, these materials were known as “pleather” or vinyl. Today, better finishes have turned thin plastic films into convincing leather lookalikes.

Most vegan leathers consist of polyurethane (PU) or polyvinyl chloride (PVC) coatings bonded to fabric backings. They are waterproof and easy to emboss, but they are also petroleum-derived plastics.

When the surface of a PU‑coated bag cracks or peels, the damage is more than cosmetic. As the coating breaks down, it sheds microplastics into the environment.

The plastic underneath the plants

In response to concerns about plastic, new fake leather materials have been developed from pineapples, mushrooms, apples, grapes and even cacti. These bio-based options are often sold as the sustainable answer.

However, using a plant does not automatically make a product better for the environment.

The issue lies in how these materials are made. A “pineapple leather” shoe may be praised for its plant fibres, but those fibres are usually held together with plastic resins to make the material durable.

The result is a mixed material that cannot be recycled in Australia, even though marketing often focuses on the plant ingredient and hides the plastic underneath.

Plant leather doesn’t last long

A key challenge with many vegan leather alternatives is strength. Raw plant fibres are too weak to handle the repeated wear and pressure faced by shoes, bags and car seats. To improve performance, manufacturers layer plant materials onto plastic binders or polyester backings.

Even then, many of these materials break down sooner than real leather and cannot be properly repaired. Traditional leather can be conditioned, patched and allowed to age over time, but plant-based alternatives tend to fail once the surface coating cracks or peels.

A mushroom- or apple-based bag also cannot be composted because of the plastic beneath its surface, meaning it reaches disposal much sooner. Some plant-based vegan leather products have reported lifespans of as little as two years.

This points to a broader issue. In a circular economy that prioritises reuse, repair and material recovery, sustainability is about keeping products in use and at their highest value for as long as possible.

Brands must walk the talk

The problems hidden by elusive marketing labels are becoming harder to ignore. The Australian Competition and Consumer Commission (ACCC) has made it clear broad labels such as “sustainable” or “eco-friendly” must be backed up with evidence.

If brands use the word “vegan” to suggest lower environmental impact, they must be able to prove that claim by looking at the product’s full life cycle.

At the same time, the Productivity Commission’s 2026 inquiry into the circular economy highlights Australia’s growing problem with products that cannot be recycled. As product stewardship schemes expand, durability, recyclability and what happens to a product at the end of its life will matter as much as animal welfare.

The ethical distinction

None of this means animal leather comes without environmental or chemical costs. These include methane emissions from livestock and the toxic chemicals used in tanning. For many consumers, avoiding animal-derived materials is still an important ethical choice.

However, “vegan” and “sustainable” are not the same thing. One describes what has been left out of a product, while the other describes how that product performs over its entire life. Treating the two as interchangeable can replace meaningful progress with reassuring labels.

The takeaway is a call for material honesty. Sustainability can’t be reduced to a single word or ingredient. It’s measured by how long a product stays useful before it needs to be thrown away. A bag that avoids animal materials but breaks down within a few years simply creates waste sooner.

If vegan alternatives are going to be sustainable, they must be designed to last. Sustainability is measured in years of use, not words on a tag.
