Amid growing concerns about the textile industry’s environmental impact, there is pressure to find greener clothes for your wardrobe, from activewear to knitwear. Unfortunately, fashion greenwashing makes it harder for you and all other consumers to figure out which clothing brands offer the most eco-friendly garments. So, we had to ask: Which are the most sustainable knitwear brands?

The most sustainable knitwear brands are Indigenous, Johnstons of Elgin, and Rifò, which source low-impact fabrics, adhere to responsible production, and strive for circularity. In addition, Paka and Mila.Vert are committed to waste reduction and supply chain traceability. 

Whether you are searching for a knit coat, a cozy sweater, or a trusty pair of socks 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 knitwear brands and how they ensure sustainable, ethical practices. 

Here’s How We Selected the Most Sustainable Knitwear Brands

Knitwear can be one of the higher impact and less sustainable clothing items due to the use of resource-intensive conventional-farmed wool or cotton fabrics. 

“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

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.

Indigenous: Organic, Fair Trade Clothing

Indigenous was founded in California in 1993 by Scott Leonard and Matt Reynolds with a vision of creating a groundbreaking socioeconomic apparel model. Today, they are renowned for their sustainable and ethical fashion, offering a wide range of organic, fair trade knitwear options.

“Each piece of clothing we make is not only soft on your skin, but also soft on your earth.Impeccably handmade and unique.”

Indigenous

Indigenous ensures sustainability by using exclusively natural and organic fabrics, including alpaca wool from free-range, family-owned herds, USDA-certified organic cotton, and TENCEL™. Thanks to their use of fabrics cultivated from pesticide-free farms, Indigenous helps to keep 400 lbs of pesticides off the land every year. Further down the life-cycle in the manufacturing stage, they use low-impact dyes certified by OEKO-TEX^® STANDARD 100 to be clear and free of harmful chemicals. Their PURE Collection includes undyed items made with alpaca wool and organic cotton. Specifically, by creating a demand for undyed colored alpaca wool, they actively increase the genetic diversity of Peru’s alpaca populations, which are dominated by sought-after white alpacas and their dye-absorbent white coats. 

Indigenous ensures their ethics by committing to the fair treatment of the artisans who make their clothes and the animals providing the fleece. They adhere to standards based on the World Fair Trade Organization, providing their artisans with safe working conditions and paying them a fair living wage. They also source exclusively from small-scale ranchers who treat their alpacas with care and reverence. 

Indigenous has made grants available to many organizations through the Fair Values Fund. These include Daily Acts, AA Foundation, Good World Solutions, Social Venture Network, Green America, Not for Sale, Ceres Community Project, and Turning Green. Additionally, they are actively involved in improving their artisans’ lives, such as by providing free training for women, bringing clean drinking water to communities in the arid Andean Highlands, supporting ever-increasing access to quality, low-cost childcare for artisans, and offering quality education for their children.

Johnstons of Elgin: Ethical Knitwear From Established Luxury Clothing Label 

Johnstons of Elgin was founded in Scotland in 1797 as a family business making the finest woven products from the finest fibers. Today, they are a B Corporation, recognized for their efforts to lower their ecological impact, eliminate their production waste, and strive for circularity. 

“We have worked with natural, renewable, biodegradable fibres since 1797 and strive to reduce our environmental footprint year after year.”

Johnstons of Elgin

Johnstons of Elgin prioritizes sustainability by setting up a low-carbon footprint and low-waste production using mainly natural fibers while working to preserve grasslands, the starting point of their cashmere fibers. Natural fabrics, including cashmere, merino lambswool, and sheep wool account for 99.88% of all fibers used in their portfolio. Further down the life-cycle in the manufacturing stage, Johnstons of Elgin strives to reduce manufacturing waste; in fact, 87% of their manufacturing waste is recycled to create other products. Specifically, batch ends of yarns and cut-offs are redyed to be used in scarves, while waste fiber goes into fillings or insulation materials whenever possible. Plastic, if used during the manufacturing process, is reused or recycled. Furthermore, the brand lowers their carbon footprint by increasing energy efficiency and working with energy providers possessing renewable energy certificates. Johnstons of Elgin’s incentives in reducing energy usage include investing in energy-efficient lighting, improving boiler maintenance, and implementing air-source heat pumps. Johnstons of Elgin also uses low-impact, non-toxic dyes in all of their products. Lastly, they strive for circularity by opting for high-quality, recyclable materials; offering repair services; and facilitating the recycling of their cashmere products. 

Johnstons of Elgin ensures their ethics by striving for transparency in how their products are made. Some of their products now have a Digital ID, enabling traceability from fiber to finished garment. Regarding the people making their products, they pay a living wage, provide training for personal development, recognize trade unions, and uphold health and safety. They also trace most of their supply chain. Furthermore, animal welfare is held at the heart of their operation. Specifically, they source cashmere with Sustainable Fibre Alliance (SFA) certification and mulesing-free merino sheep wool and lambswool with Responsible Wool Standard certification. 

Johnstons of Elgin is one of three founding members of the Sustainable Fibre Alliance (SFA), a nonprofit international organization working in the cashmere supply chain. SFA funds various programs in Mongolia to train communities and promote ecological and social projects to restore grasslands, ensure animals’ well-being, and secure herders’ livelihoods. For example, their Young Herders program, “Kharaatsai” (Young Swallows), gives students a deeper understanding of their natural environment through biodiversity, weather patterns, and soil health classes.

Rifò: Fashionable and High-Quality Garments Made With Recycled and Recyclable Materials 

Rifò was founded via a crowdfunding campaign launched at the end of 2017 by Niccolò, Clarissa, Michele, and Fiammetta, aiming to create a fashionable and high-quality garment line made entirely in Prato, Italy, with 100% recycled and recyclable fibers. Today, they are an emerging sustainable apparel brand, selling their clothes and accessories in shops around Europe and globally via their online store. Rifò also has recycled knitwear for both women and men. 

“Our planet is no longer capable of sustaining the rhythms of Fast Fashion: it is necessary to create sustainable alternatives for a better future.”

Rifò 

Rifò approaches sustainability by committing to using recycled and recyclable fibers. They opt for natural, biodegradable materials composed of at least 50% recycled fibers, such as recycled cashmere, recycled wool, recycled (organic) denim, recycled (organic) cotton, and recycled silk. Also, their packaging is made with recycled cardboard and is plastic-free. On top of that, they embed circularity principles in every step of their products’ life-cycle, meaning beyond material sourcing, these principles apply to designing, manufacturing, and end-of-life too. Additionally, Rifò fights textile waste by running a presale system to minimize overproduction and take back used garments to reuse or recycle. Customers can trade in their pre-loved items for a €10 ($11) discount voucher by using a free-of-charge home pickup service or a drop-off box. In 2022, 14% of the recycled materials used in their clothes was collected directly from their circular service. Rifò also joined the movement to boycott Black Friday’s rampant consumerism. Last but not least, they are B Corporation certified. 

Rifò binds their suppliers with a Code of Conduct covering four of the ILO’s Fundamental Principles and Rights at Works. They also trace most of their supply chain.

Rifò donates €2 ($3) from each purchase on their online store to Nei Nostri Panni, a social impact project to train textile-recycling artisans and spinners who are in vulnerable situations. Additionally, Rifò has supported Fashion Revolution by donating part of the sale from their regenerative cashmere sweater, in an effort to spread awareness for “Green Friday”, an alternative to the hyperconsumerism-supporting Black Friday.

Paka: Knitwear Made With Traceable Alpaca Wool 

Paka was founded in Peru by Kris Cody via a Kickstarter crowdfunding campaign launched in 2017 with a mission to create natural, all-purpose clothing for people who love the outdoors. Today, Paka is a B Corporation selling knitwear for the outdoors made with alpaca wool from the Andes Mountains. 

“Paka was created to bring you closer to where your clothing comes from, what it’s made of, and who made it.”

Paka

Paka prioritizes sustainability by innovating and making low-impact, high-performing fabrics with ethical alpaca wool. In particular, they source alpaca wool from small-scale, family-owned herds. Each herd contains 60 to 90 animals roaming free throughout the Peruvian Andean Highlands. After the fleece is shorn, the fiber is collected and separated by hand before being colored (if needed) with environmentally friendly dyes certified by OEKO-TEX^® and GOTS. Half of the energy used in their alpaca wool spinning process comes from solar energy. Further down the life-cycle in the transporting stage, Paka alpaca products are delivered carbon-neutral through their partnership with Ecocart. The packaging is also fully biodegradable.

Paka ensures their ethics by making their alpaca wool products fully traceable, from free-roaming alpacas up in the Andes Mountains to customers’ homes in the US. The 100+ Quechua women weavers who make Paka’s products are employed by the brand and paid 4 times the family living wage. Regarding alpaca treatment, Paka uses a special technique (Inca Esquila) to minimize the time and stress posed upon the animal during the shearing process. 

Through their partnership with Peruvian Hearts, Paka supports the education of underprivileged Peruvian young women with 1% of their annual revenues. Another 1% of their sales supports regenerative agriculture and alpaca families. Additionally, they provide free weaving training for women who want to learn a skill, as well as a “Wawa Wasi” (daycare) in the neighborhood, with full-time supervision and a trained psychologist to enable mothers to go to work. Lastly, Paka is helping to build an NGO that preserves the Inca traditions.

Today, they are a recognized leader in sustainable outdoor clothing and gear, celebrated for their commitment to transparency, eco-conscious materials, and ethical manufacturing. Finisterre sells knitwear for both men and women. 

“Yet from our cliff top workshop, we stay true to our original design ethos of functionality and sustainability, remaining committed to product, environment and people.”

Tom Kay, Founder of Finisterre

Finisterre places circular sourcing at the center of their sustainability commitment. In particular, they use renewable and recyclable textiles and biodegradable natural fibers and finishes. At least 50% of their clothes are made using recycled fabrics. For example, in 2022, 87% of the synthetic polymer fabrics used in Finisterre clothes were made using recycled fabrics, including polyester recovered from post-consumer and post-industrial waste. They also use low-impact natural fibers, including GOTS-certified organic cotton, hemp, linen, and bamboo. In 2019, they replaced all plastic packaging with water-soluble, ocean-safe, and biodegradable “Leave No Trace” garment bags. Finisterre also strives to reduce textile waste by offering repair services and giving in-store credits for gear trades-in, which would be reconditioned for resale. On top of that, they implement various incentives to reduce their carbon footprint, including switching more of their stores and offices to renewable energy tariffs and transporting products using less carbon-intensive modes on land and sea. Last but not least, Finisterre is a B Corporation. 

Finisterre is committed to full transparency in their supply chain, holding their partners to the high standards in their Code of Conduct and their Anti-Slavery & Trafficking Policy. Additionally, they partner with Fair Working Conditions (FWC), enabling the mapping of their supply chain, the screening of suppliers, and targeted audits at high-risk locations. Their facilities are also listed on Open Supply Hub. Lastly, Finisterre’s ethical values extend to their dedication to saving the sea. For example, they provide a free resource to inspire ocean activism. 

Finisterre provides financial support to various giving-back campaigns and programs through the Finisterre Foundation, championing ocean access for all. For example, Finisterre turned 2021’s Black Friday into Blue Friday, where they swapped discounts for donations, raising funds for The Wetsuit Project, which adapts wetsuits for children and adults with various disabilities to access the sea. In 2022, Blue Friday was used again to raise money supporting Level Water to provide specialist swimming lessons for children with disabilities. Other projects include The Seasuit Project, City Kids Surfing, Seasuit Donation, and Art Auctioning for Good.

The Knotty Ones: Traditional Baltic Knitwear Made Sustainably in Small Batches 

The Knotty Ones was founded in 2014 by three Lithuanian natives and friends—Akvilė Meškauskaitė-Dobrajs, Danutė Rasimaviciute, and Sandra Pangonyte—with a vision to provide stable jobs, fair wages, and financial independence to women in marginalized areas of Lithuania. Today, The Knotty Ones operates between New York and Vilnius, offering luxury knitwear while supporting female artisans and female-founded factories.

Their Žemiau and Ethno alpaca sweaters are undyed and come with Peru Fair Trade Certification, reducing their chemical use. Thirdly, The Knotty Ones operates a “fully fashioned” production model where each sweater piece is pre-ordered, individually shaped, and factory-knitted before being sewn together by hand.

The Knotty Ones maintains their ethics by creating fair partnerships with their female knitters and factory partners. They offer weekends off, living wages, and safe working conditions. Additionally, the artisans who work on The Knotty Ones’s handmade pieces choose their work schedules (part-time, full-time, or while their kids are napping) from the comfort of their homes, with everything they need to work safely and comfortably.

Sheep Inc.: Merino Wool Knitwear From a Carbon-Negative Brand 

Sheep Inc. was founded in 2001 in London, England, by Edzard van der Wyck and Michael Wessely with a mission to create exceptional knitwear and an overall different kind of brand—one that would challenge the norms of the fashion industry and redefine the concept of luxury. Today, Sheep Inc. is a carbon-negative fashion brand and a true pioneer in environmental responsibility. 

“To us, transparency isn’t a fleeting trend but a steadfast commitment. We believe in equipping our consumers with complete knowledge about their purchase’s journey. The Connected Dot stands as our unwavering promise, a testament to our dedication to clarity and authenticity.”

Sheep Inc.  

Sheep Inc. ensures their sustainability by making data-driven decisions to lower their environmental impacts. They partner with other organizations like Carbon Footprint Ltd to measure their impact and adapt their choices according to the data. For example, they source merino wool from regenerative sheep farms in New Zealand instead of local farms in the UK because the former has a carbon footprint of -14kg CO₂ per kg, while the latter has an average carbon footprint of 20-30 CO₂ per kg. Even with the emissions from transportation, their choice of merino wool comes with a much lower carbon emission. Additionally, the brand actively supports regenerative farming to ensure that they give back more than they take, leading to Sheep Inc. being a carbon-negative operation. Further down the life-cycle in the manufacturing step, the brand reduces their carbon emissions by using solar energy to power their zero-waste 3D knitting machines. Lastly, they design timeless pieces that don’t just last but also outlast, contributing to textile waste reduction. They ensure longevity against wear and tear by reinforcing stress points and choosing resilient stitching. On top of that, the brand provides a merino wool care guide and a repairing service to help extend the lifespan of each and every Sheep Inc. garment. 

Sheep Inc. commits to transparency across their supply chain. Each Sheep Inc. garment comes with an NFC tag ingeniously integrated into the hem, enabling tracing every step of the garment journey, starting with a single thread spun from the fleece of a hand-selected Merino sheep in New Zealand to wool treating, spinning, and knitting across Europe (Italy, Bulgaria, Portugal, and Romania). They also publish the life-cycle’s greenhouse gas emissions of their products (cardigans, hoodies, medium knits, V-neck sweaters, light knits, and beanies), staying transparent about their climate impact. Regarding animal welfare, they source exclusively from farms certified by ZQ, which ensures sheep are well-fed and resilient against natural stresses, free to live naturally, and free from discomfort and distress. 

Sheep Inc. donates 100% of the profits from each design in their Sheep Inc. x LUAS collection to Rainbow Migration, an organization providing practical and emotional support for LGBTQI+ people seeking asylum in the UK. Additionally, they earmark a portion of the profits to form the Radical Farming Fund, which supports groundbreaking projects in sustainable farming.

Achiy: Slow-Fashion Clothing Made With Natural Materials in Partnership With Artisans 

Achiy was founded in Hamburg, Germany, in 2020 by Vivica and Lennard Pietz to change the resource-damaging fashion production and encourage more conscious consumption. Today, they are recognized for preserving ancient cultures, wisdom, and production techniques that have been passed down for hundreds of years and over many generations. 

“In the best possible harmony with nature, we create limited collections with sense, which offer an absolutely suitable answer to the fast fashion industry.”

Achiy

Achiy approaches sustainability by exclusively using certified yarns of known origin that use biodegradable dyes approved by AZO, OEKO-TEX^®, and REACH. Their alpaca wool is also certified by the International Alpaca Association, ensuring quality and durability, while their organic cotton is GOTS-certified. For the “Designed by Another Life” labels on their products, they use pineapple leaves, which are normally a by-product but are now processed into alternative leather. Regarding carbon emission reduction, they use reusable packaging that can be used for at least 20 order cycles from their warehouse to their customers and back. Additionally, Achy’s clothes are made in small batches, celebrating the craft of the artisans while avoiding textile waste. 

Achiy is transparent about the knitters who make each and every one of their products. Furthermore, their clothes are produced in workshops that are part of the Fashion Revolution, where artisans are paid fairly for their work. 

Achiy encourages customers to return the RePack packaging that their clothes come in. For every RePack returned, they donate 2€ (3$) to the Kinsacchocha Community in Paru Paru, Cusco, where 10 indigenous families live at an altitude of 4,010 meters (2.5 miles).

FTC Cashmere: Climate-Neutral Cashmere Knitwear From Zero-Waste Production 

FTC Cashmere was founded in Switzerland in 2003 by husband and wife Andreas Knezovic and Jutta Knezovic as a premium fashion brand focusing on human and ethical values. Today, FTC Cashmere is recognized as a cashmere apparel brand with guarantees of ethically correct goods, fair business dealings for all participants, sustainable pricing, and humane conditions throughout the production chain.

“Specializing in high-quality, cashmere knits in the premium segment, FTC Cashmere stands for elegant, pure, coveted fashion and luxury articles as well as for a strong sense of responsibility with respect to fairer, ethically correct manufacturing conditions.”

FTC Cashmere

FTC Cashmere promotes sustainability by innovating to achieve zero-waste production and offsetting all of their carbon emissions. They have developed a technique to seamlessly join the threads of the leftover yarns, which remain on the bobbin after a garment is knitted. Thanks to this technology, FTC Cashmere could recirculate the cuts-off to make high-quality cashmere products in their upcycled fashion line “UpKnit – Upcycling for Uniqueness by FTC®” while leaving behind no yarn waste. Between 2019 and 2022, they reused almost a ton of waste yarn. Additionally, they now use FSC-certified recycled paper bags instead of polybags for packaging to reduce plastic consumption and waste. They further reduce their impact by offsetting all carbon emissions coming from their operation in reforestation and solar energy projects in China, where their farms and factories are located. Lastly, FTC Cashmere is certified MADE IN GREEN by OEKO-TEX®, an all-encompassing sustainability label representing transparency, social responsibility, environmentally friendly operations, and consumer safety.

FTC Cashmere ensures their ethics by committing to fair treatment toward the workers who make their products and the cashmere goat herds. They employ all textile workers and partners in China and thus ensure living wages, a high level of job security, and above-average employment conditions. Additionally, FTC Cashmere signed an exclusive contract with the local government and the farmers for the purchase of the cashmere raw material at market prices plus a premium to make sure farmers are paid fairly. Additionally, they trace most of their supply chain. Regarding animal welfare, they work with national universities to have the health of the cashmere goats regularly checked by specialists. They set eight grounding principles spanning from grounds for breeding, general health conditions, keeping of animals, the shearing process, the transportation of animals, and all other stages of life while documenting each and every goat to ensure fair treatment. 

FTC Cashmere gives back to the farmers and the communities where their products are made by building schools in the area. The schools, which are planned, financed, and constructed entirely by FTC^®, provide basic school education to more than 1,000 children from 4 to 14 years of age.

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

It is important to buy products made of 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. 

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 wool 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 that are 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 wool (or wool-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

Knitwear is a category of clothing that is often high-impact due to its use of resource-intensive, conventionally farmed wool or cotton. 

By purchasing knitwear 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 knitwear brands:

• Indigenous
• Johnstons of Elgin
• Rifo
• Paka
• Mila.Vert
• Finisterre
• The Knotty Ones
• Sheep Inc.
• L’Envers
• Nui Organics
• ASKET
• Norgäte
• Unrecorded
• Foxology
• Achiy
• FTC Cashmere

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

1. Buy second hand, recycled, or upcycled knitwear made with low-impact materials. 
2. Keep your knitwear for as long as possible.
3. At the end-of-life of your knitwear, upcycle the materials to extend their usage and arrange for them to be recycled or properly disposed of.

Stay impactful,
