Affiliate Disclosure

Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

• Most of these links are informational-based for you to check out their primary sources with one click.

• But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?

1. First, and most importantly, we still only recommend products that we believe add value for you.

2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?

1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

Stay impactful,

Amid growing concerns about the environmental impact of the textile industry, the spotlight is shifting toward natural fibers as the eco-friendly materials for making clothing. Plant-based fibers such as linen, kapok, and ramie have garnered much attention for their sustainability attributes. But are all natural fibers equally sustainable, or are some potentially a bit greenwashed? So, we had to ask: Which are the most sustainable natural fiber clothing brands? 

The most sustainable linen clothing brands include MATE the Label, NATASHA TONIC, and Finisterre, which use low-impact natural fibers, employ full traceability, and strive for textile circularity. In addition, Opera Campi and Nui Organic commit to lowering carbon emissions and chemical usage.

Whether you are searching for a T-shirt, a sweater, or some comfortable underwear to add to your wardrobe without negatively impacting the soil, the water, the animals, and other people, there is a brand for you. So, let’s keep reading to learn more about the most sustainable linen clothing brands and how they ensure sustainable, ethical practices. 

Here’s How Sustainable Natural Fibers Generally Are

Natural fibers, either coming from plants or animals, are generally renewable and biodegradable, unlike synthetic fibers derived from fossil fuels. However, growing certain crops or raising certain animals for fibers can have such significant adverse environmental impacts that they reduce the overall sustainability of the fabrics. The Common Objective’s Made-By Environmental Benchmark for Fibres ranks natural fibers in a wide range, from class E, the least sustainable fiber class, to class A—the most sustainable fiber class.

“Sustainable: The ability to be maintained at a certain rate or level | Avoidance of the depletion of natural resources in order to maintain an ecological balance”

Oxford Dictionary

To understand the sustainability of natural fibers, we’ve assessed the life-cycle and each stage’s sustainability. This life-cycle assessment (LCA) is a method to evaluate the environmental impacts of products and materials. Here’s a quick summary of our LCA of natural fiber!

What makes sustainable natural fibers: Hemp and linen are two plant-based natural fibers with the highest level of sustainability. These fiber crops are often grown and processed without toxic synthetic chemicals and heavy irrigation and have high carbon sequestration potential, helping to mitigate the climate crisis. 

Additionally: Some fiber crops also provide other products along with fibers. For example, flax plants provide oil, food, and dietary supplements, as well as linen fibers. 

Here’s How We Selected the Most Sustainable Natural Fiber Clothing Brands

The brands on this list were chosen based on their commitment and actions to promote sustainable practices while reducing the environmental impacts of the textile industry. 

They are transparent about their materials, processes, and workforce management within their supply chain. 

Some brands focus their efforts on reducing waste and optimizing natural resources while others strive to reduce the carbon footprint of their clothes. 

All of these brands share the commitment to reshape the textile industry toward a more sustainable and Earth-friendly sector. 

These Are the 10 Most Sustainable Natural Fiber Clothing Brands

Overall, these natural fiber clothing brands are sustainable. Yet, they take various approaches to reduce environmental impacts and uphold ethical standards. Let’s dive into each brand and find out more.

Fabrics Made With Natural Fibers: Breathable Materials That Biodegrade at the End Of Their Life 

Fabrics made with natural fibers are generally more breathable than fabrics made with synthetic fibers, saving water and energy for washing and drying during the usage stage. Natural fibers are generally biodegradable and compostable, enabling various end-of-life options. 

Here are the life-cycle stages of natural fabrics and each stage’s sustainability assessment:

• Sourcing natural fibers from farms: Sourcing conventional cotton fibers—the most commonly sourced after natural fibers—is unsustainable. The cotton crop is water-thirsty and pesticide-dependent. Also, the widespread monoculture in cotton cultivation depletes the soil and necessitates synthetic fertilizer in many growing regions. However, the sourcing stage of natural fabrics can be sustainable when raw materials are recycled from waste or obtained from organic farming systems. Additionally, many fiber crops, including linen, hemp, and jute, require little input to provide a high fiber yield while having a strong carbon sequestration potential.
• Manufacturing of natural fiber clothing: The sustainability of manufacturing natural fiber clothing varies depending on the natural fibers used. Manufacturing natural fabrics, such as cotton, wool, and silk, can be unsustainable because the processes are energy, water, and chemical-intensive. In contrast, producing natural fabrics from some plant-based fibers, such as linen, hemp, and kapok, can be sustainable, mainly because it can be done mechanically without adding toxic chemicals. 
• Transportation of natural fiber clothing: Transporting natural fabrics is generally unsustainable. It can be a carbon-intensive life-cycle stage for clothing and household items made with natural fibers due to the distances covered and emissions associated with transporting vehicles. Natural fabrics typically travel from fields (where plants or animals are farmed) to factories, then sorting centers, shops, and consumers’ homes before going to recycling centers or landfills. 
• Usage of natural fiber clothing: Using natural fabrics is generally sustainable. Natural fabrics are generally breathable. They don’t need to be washed frequently—much less often than synthetic fabrics—thus saving water and energy. Most commonly used natural fibers are strong, meaning materials made with those fibers can last long before a replacement is needed. Lastly, washing natural fabrics doesn’t cause microplastics to be released into the environment. 
• End-of-life of natural fiber clothing: The end-of-life stage for natural fabric is generally sustainable. Natural fabrics are made with natural fibers, resulting in the material being biodegradable and compostable. 

Some natural fibers, including linen and hemp, are among the most sustainable textile materials. They are durable and biodegradable materials. Fiber crops sequester carbon, helping to mitigate the climate crisis. 

Why Is It Important to Buy Products Made of More Sustainable Fabrics

It is important to buy products made from more sustainable fabrics because a sustainable textile industry has a lower carbon footprint, helps save natural resources, and is better for forests, animals, and humans alike. 

Buying Sustainable Fabrics Reduces Your Carbon Footprint 

The production of clothing and footwear is estimated to contribute 10% of global greenhouse gas emissions—more than all international flights and shipping combined. If the fashion industry were a country, it would be the fourth largest emitter of carbon dioxide. 

One way to reduce the carbon footprint of the clothes you buy is to opt for sustainable fabrics. Sustainable fabrics, which are often made with natural or recycled fibers, have relatively low carbon footprints compared to petroleum-based fabrics. For example, organic cotton made in the US has a carbon footprint of 2.35 kg CO₂ (per ton of spun fiber)—a quarter of polyester’s carbon footprint.

Buying Sustainable Fabrics Reduces Demand for Natural Resources and Waste Management

The textile industry uses water and land to grow cotton and other fibers. It is estimated that 79 billion cubic meters of water were used for the sector worldwide in 2015. For example, producing a single cotton T-shirt requires as much water as one person drinks for 2.5 years (2,700 liters of fresh water).

Worse yet, the textile economy is vastly more linear than circular: the largest amount of resources used in clothes ended up in landfills (instead of being recycled to remake clothes). According to a report by the Ellen MacArthur Foundation,

• Less than 3% of materials used in the textile economy in 2015 came from recycled sources.
• In other words, more than 97% of resources used in making clothes are newly extracted. 

When clothing items are disposed of within a short period of time—under a year in the case of half of the fast fashion clothes—the natural systems that provide raw materials for fabrics don’t have enough time to recover and regenerate, which could lead to ecological breakdown. 

Sustainable fabrics are made with less water and emissions while lasting longer:

• Because they are durable, you don’t need to buy new clothes too often. 
• Thus, you help reduce the pressure to extract more resources for making new items. 

Similarly, making and consuming sustainable fabrics made with recycled materials reduces the demand for virgin materials while helping tackle waste management. 

Buying Sustainable Fabrics Encourages Sustainable Management of Forests

Sustainable plant-based fabrics are made with raw materials from forests and plantations that are sustainably managed, such as complying with FSC standards. 

When you buy sustainable plant-based fabrics, you discourage unsustainable forestry practices like illegal logging. You can help reduce deforestation, biodiversity loss, and the effects of climate change. 

Buying Sustainable Fabrics Encourages Fairer Treatment of Animals 

The fashion industry is rife with animal mistreatment when it comes to making animal-based fabrics like wool or silk. Every year, billions of animals suffer and die for clothing and accessories.

Buying sustainable vegan alternatives can help to reduce the pressure on raising more and more animals to meet the demand for animal-based fabrics while sacrificing their well-being and lives. 

Suppose you have to buy fabrics made with, for example, wool or silk; make sure you only choose brands committed to cruelty-free products. In that case, you help advocate better treatments for animals raised within the textile industry. 

Using Sustainable Fabrics Encourages Fairer Treatment of Textile Workers 

Recent statistics from UNICEF estimated as many as 170 million child laborers worldwide, many of whom were engaged in some form of work in the textile industry. They don’t get paid minimum wages and often work long hours. 

When you buy sustainable fabrics from brands transparent about the working conditions at their factories, you discourage the use of child labor and help promote better working conditions for textile workers.

How Can You Generally Buy More Sustainable Fabrics

The key to sustainably buying fabrics is to check on relevant environmental and original certifications. 

For natural fabrics: 

• Global Organic Textile Standard (GOTS): A globally recognized certification system that ensures a certain threshold of organic content has been met. It covers manufacturing, packaging, labeling, transportation, and distribution (but not what happens in the fields where crops are grown). 
• USDA Certified Biobased Product: The USDA BioPreferred® Certification is a voluntary certification offered by the United States Department of Agriculture. The certification identifies products made from plants or other renewable materials.
• Ecolabel: Ecolabel is the official European Union voluntary label recognized worldwide for certified products with a guaranteed, independently verified low environmental impact. The label requires high environmental standards throughout the entire life-cycle: from raw material extraction through production and distribution to disposal. It also encourages companies to develop innovative, durable, easy-to-repair, and recyclable products. 

For plant-based semi-natural/semi-synthetic fabrics:

• Forest Stewardship Council: An FSC certification ensures that the wood (or wood-like material) comes from responsibly managed forests that provide environmental, social, and economic benefits.
  
  There are two types of FSC Certification: 
  • FSC Forest Management Certification, with a focus on the origin of the wood—the forest. 
  • FSC Chain of Custody Certification, which focuses on the path from the forest to the customer’s home. 

• Program for Endorsement of Forest Certification: PEFC’s approaches to sustainable forest management are in line with protecting the forests globally and locally and making the certificate work for everyone. Getting a PEFC certification is strict enough to ensure the sustainable management of a forest is socially just, ecologically sound, and economically viable but attainable not only by big but small forest owners.

For recycled fabrics:

• Recycled Claim Standard (RCS): The Textile Exchange RCS was originally developed as an international, voluntary standard that sets requirements for third-party certification of Recycled input and chain of custody. 
• The Global Recycled Standard (GRS): The Global Recycled Standard (GRS) is an international, voluntary, full product standard that sets requirements for third-party certification of Recycled Content, chain of custody, social and environmental practices, and chemical restrictions. It can be used for any product with more than 20% recycled material.

For all types of fabrics:

• STeP by OEKO-TEX®: STeP by OEKO-TEX® is an independent certification system for brands, retailers, and manufacturers from the textile and leather industry. It communicates organizational environmental measures, including reducing carbon footprint and water usage.
• OEKO-TEX^® Standard 100: OEKO-TEX® labels aim to ensure that products pose no risk to human health (i.e. containing banned chemicals). 

Some certifications that are signaling brands’ efforts toward lowered environmental impacts and a circular economy are: 

• B Corp Certification: The label B Corp is a certification reserved for for-profit companies. Certified holders are assessed on their social and environmental impacts. 

• Cradle2Cradle certification: Cradle2Cradle provides a standardized approach to material circularity. It assesses whether products have been suitably designed and made with the circular economy in mind covering five critical categories: material health, material reuse, renewable energy and carbon management, water stewardship, and social fairness.

Final Thoughts

Natural fabrics are on a spectrum from unsustainable to sustainable, largely depending on the farming systems in which animals are raised or the plants are cultivated for the natural fibers, along with the use of energy and chemicals during manufacturing. Natural fibers from plants, in particular, have the climate benefits from plants’ carbon sequestration. Additionally, some natural fibers, such as linen, hemp, and wool, are wonderful textile materials with exceptional strength and breathability. 

By purchasing new or pre-loved natural fiber clothes from brands that commit to sustainability, you support their mission to create a fairer and less harmful textile industry for all lives on Earth. 

Here is the list (again) of the most sustainable natural fiber clothing brands: 

• MATE the Label 
• NATASHA TONIC
• Finisterre
• Opera Campi
• Nui Organic
• WAMA
• People Tree
• Beaumont Organic 
• VAUDE
• Thought

To make your use of these fabrics even more sustainable, follow these steps:

1. Buy second-hand, recycled, or upcycled clothes made with natural fibers
2. While using natural fiber clothes, maximize the number of wears between washes and keep them as long as possible.
3. At the end-of-life of your natural fiber clothes, upcycle the materials to extend their usage and arrange for them to be recycled or properly disposed of.
