How to Identify Sustainable Fabrics as A Fashion Consumer

The fashion industry, notorious for its significant pollution, contributes approximately 10% of global carbon emissions and 20% of wastewater. Additionally, old clothes go into landfills, further adding to the environmental burden. Sustainable fabrics are key to reducing these impacts.

When choosing clothes, making informed choices is more important than ever. This guide aims to help you identify sustainable fabrics, empowering you to make eco-friendly choices that benefit both you and the planet.

Understanding Sustainable Fabrics

What Are Sustainable Fabrics?

Sustainable fabrics are materials that are produced in ways that minimise their impact on the environment and promote ethical practices. Throughout their lifecycle — from growth or production, to use, and disposal — these fabrics are crafted to mitigate environmental harm. They address key issues caused by the fashion industry, such as excessive water use, chemical pollution, and poor labour practices, aiming to resolve both environmental and social challenges.

What makes a fabric sustainable?

There are a few key factors that make a clothing material sustainable:

  • Reduced Carbon Footprint

Sustainable fabrics are typically sourced from renewable materials, recycled or upcycled fibres. They produce lower carbon emissions compared to traditional textiles.

  • Less Water Usage

Sustainable clothing materials use less water in production, conserving freshwater resources and reducing textile manufacturing’s environmental impact.

  • Reduced Chemical Use

Sustainable fabrics prioritise natural and non-toxic dyes and finishes. This approach minimises chemical pollution in waterways and reduces exposure to harmful substances for workers and consumers.

  • Ethical Labour Practices

Sustainable clothing materials ensure fair pay and safe working conditions for everyone involved, from farms to factory workers, promoting social responsibility alongside environmental stewardship.

  • Durability

Sustainable fabrics are crafted from durable, high-quality materials, designed to last longer and minimise the need for replacements. This approach effectively reduces waste and lowers environmental impact.

  • Biodegradability

Unlike synthetic fibres that contribute to microplastic pollution, many sustainable fabrics are biodegradable. They naturally break down at the end of their lifecycle, reducing landfill waste.


Common Sustainable Fabrics and Their Benefits

Organic Cotton


1. Organic Cotton

Organic cotton is grown without synthetic pesticides, artificial fertilisers, or other toxic chemicals. It uses significantly less water (90% less) and energy compared to conventional cotton. Organic cotton is also safer for farmers and promotes a healthier ecosystem.

2. Linen

Linen is a natural fabric made from the flax plant. It captures carbon and requires minimal water, fertiliser, or pesticides. Highly durable and breathable, linen is also biodegradable, providing long-lasting wear and comfort, making it a great sustainable fabric.

3. Hemp

Hemp is nearly identical to linen in its sustainability. It’s a versatile, natural fibre derived from the hemp plant. Hemp grows even more quickly than linen, requires little water and no pesticides, making it highly sustainable. It is also durable, biodegradable, and naturally resistant to mold and UV light.

4. Bamboo

Bamboo is a fast-growing plant often used to create sustainable fabrics. It requires minimal water and no pesticides, making it an eco-friendly option. However, the process of turning bamboo into fabric can involve harsh chemicals, leading to seriously harmful environmental damage. Look for certified organic bamboo labels to ensure it’s sourced from sustainably managed forests and manufactures. 

5. TENCEL™ Lyocell

Lyocell, a rising star semi-synthetic sustainable fabric, is made from wood pulp typically sourced from eucalyptus trees. Known for its softness, breathability, and efficient moisture absorption, it offers exceptional comfort. Though its production involves chemicals, they are managed in a closed-loop system, minimising environmental impact. Produced by Austrian manufacturer Lenzing, TENCEL™ Lyocell stands out as the most sustainable option.

6. Modal

Modal, a semi-synthetic eco-friendly fabric, is made from beech tree pulp and is known for its silky feel, breathability, and high absorbency. It is more environmentally friendly than many conventional fabrics due to its sustainable sourcing. However, the chemical process involved can have environmental impacts if not managed properly. TENCEL™ Modal is produced from sustainably farmed trees, using a more energy-efficient and less toxic chemical process.

7. Wool

Wool has the potential to be a sustainable fabric when sourced from farms with ethical practices and processed using eco-friendly methods. It’s a natural protein fibre obtained from the fleece of sheep, goats, and similar animals. Wool is warm, durable, biodegradable, and typically requires less water and energy to produce than cotton.

8. Recycled Fabrics

Recycled fabric is a sustainable option made from repurposed materials like plastic bottles or old garments, which reduces waste and conserves valuable resources. It helps decrease the demand for virgin materials, therefore lowering energy consumption and carbon emissions. However, the recycling process can involve harsh chemicals and occasionally result in fibres of lower quality despite its environmental benefits. Econyl™, a regenerated nylon made from recycled fishing nets, can be recycled infinitely without losing its quality.

9. Innovative Fabrics

Last but not least, innovative sustainable fabrics. Examples include Piñatex, a vegan alternative to leather, made from pineapple leaf fibres; Bananatex™, another vegan leather, made purely from banana plants; Orange fiber, derived from the cellulose of discarded orange peels – a byproduct of the juice industry – spins waste into a luxurious, silky sustainable clothing material.

Common Unsustainable Fabrics To Avoid

While there are many excellent sustainable fabrics available, most clothes are still made from unsustainable ones, especially fast fashion brands. These brands often produce cheap, poorly made clothes without fair labour practices, resulting in landfill waste and environmental pollution from microplastics and harmful chemicals.

To make eco-friendly choices, even when buying secondhand, avoid these common unsustainable fabrics:

  • Polyester

The most commonly used fabric in fashion, polyester is a synthetic fiber derived from petroleum. Essentially, it’s plastic.

  • Acrylic

Known as “cheap wool”, acrylic is also a synthetic material, made with plastic threads derived from fossil fuels.

  • Nylon

Similar to polyester and acrylic, nylon is a synthetic fabric made from plastic, with petroleum as its main ingredient.

  • Rayon

Also called viscose, rayon is a semi-synthetic fabric usually derived from wood pulp. It is known for its silk-like feel and drape. However, its production often involves toxic chemicals. 

  • Conventional Cotton

Although it’s a natural fibre, conventional cotton requires high water consumption and pesticide use. It takes around 2,700 litres of water to produce enough cotton for one T-shirt, which is about the amount a person drinks in 900 days. Opt for organic cotton for a sustainable alternative. 

How to Identify Sustainable Fabrics as A Consumer?

Now that you understand what a sustainable fabric is, how to identify them when shopping for clothes? Here are three handy ways:

1. Read Fabric Labels

First, check the fabric information labels (usually sewn inside on the side of the garment or stated in the material section on the product page if online) for a complete breakdown of the material components. Are they made from fully sustainable fabrics or just partially? Be aware that some brands use greenwashing tactics, such as displaying an green tag of “recycled material” when it only makes up a small portion of the fabric. Carefully read the fabric labels to identify genuine sustainable materials and spot greenwashing.

2. Look for Certifications

The second method to identify sustainable fabrics is to look out for the key sustainability certifications widely used in the fashion industry:
