Sustainable fashion is a movement and process of fostering change to fashion products and the fashion system towards greater ecological integrity and social justice. Sustainable fashion concerns more than just addressing fashion textiles or products. It comprises addressing the whole system of fashion. This means dealing with interdependent social, cultural, ecological, and financial systems.
Sustainable fashion also deals with considering fashion from the perspective of many stakeholders - users and producers, all living species, contemporary and future dwellers on earth. Sustainable fashion, therefore, is the responsibility of citizens, the public sector, and the private sector. A key example of the need for systems thinking in fashion is that the benefits of product-level initiatives, such as replacing one fiber type for a less environmentally harmful option. An adjacent term to sustainable fashion is eco-fashion.
The origins of the sustainable fashion movement are intertwined with those of the modern environmental movement, and specifically the publication in 1962 of the book Silent Spring by American biologist Rachel Carson. Carson's book exposed the serious and widespread pollution associated with the use of agricultural chemicals, a theme that is still important in the debate around the environmental and social impact of fashion today. The decades which followed saw the impact of human actions on the environment to be more systematically investigated, including the effects of industrial activity, and new concepts for mitigating these effects, notably sustainable development, a term coined in 1987 by the Brundtland Report.
In the early 1990s and roughly coinciding with the United Nations Conference on Environment and Development in 1992, popularly known as the Rio Earth Summit, 'green issues' (as they were called at the time) made their way into fashion and textiles publications. Typically these publications featured the work of well-known companies such as Patagonia and ESPRIT, who in the late 1980s brought environmental concerns into their businesses. The owners of those companies at that time, Yvon Chouinard and Doug Tompkins, were outdoorsmen and witnessed the environment being harmed by overproduction and overconsumption of material goods. They commissioned research into the impacts of fibers used in their companies. For Patagonia, this resulted in a lifecycle assessment for four fibers, cotton, wool, nylon, and polyester. For ESPRIT the focus was on cotton—and finding better alternatives to it—which represented 90% of their business at that time. Interestingly, a similar focus on materials impact and selection is still the norm in sustainable fashion thirty years on.
The principles of 'green' or 'eco' fashion, as put forward by these two companies, was based on the philosophy of the deep ecologists Arne Næss, Fritjof Capra, and Ernest Callenbach, and design theorist Victor Papanek. This imperative is also linked to a feminist understanding of human-nature relationships, interconnectedness and “ethics of care” as advocated by Carolyn Merchant, Suzi Gablik, Vandana Shiva, and Carol Gilligan. The legacy of the early work of Patagonia and ESPRIT continues to shape the fashion industry agenda around sustainability today. They co-funded the first organic cotton conference held in 1991 in Visalia, California. And in 1992, the ESPRIT e-collection, developed by head designer Lynda Grose, was launched at retail. The collection was based on the Eco Audit Guide, published by the Elmwood Institute. Throughout the 1990s and early 2000s, the movement in sustainable fashion broadened to include many brands. Though the primary focus has remained on improving the impact of products through fiber and fabric processing and material provenance, Doug Tompkins and Yvon Chouinard were early to note that exponential growth and consumption are not sustainable. ESPRIT placed an ad in Utne Reader in 1990 making a plea for responsible consumption. In 2011 the brand Patagonia ran an ad and a PR campaign "Don't buy this jacket" with a picture of Patagonia merchandise. This message was intended to encourage people to consider the effect that consumption has on the environment, and to purchase only what they need.
In parallel with the industry agenda, a research agenda around sustainable fashion has been in development since the early 1990s, with the field now having its own history, dynamics, politics, practices, sub-movements and evolution of analytical and critical language. The field is broad in scope and includes technical projects that seek to improve the resource efficiency of existing operations, the work of brands and designers to work within current priorities as well as those which look to fundamentally re imagine the fashion system differently, including the growth logic. In 2019, a group of researchers formed the Union for Concerned Researchers in Fashion (UCRF) to advocate for radical and coordinated research activity commensurate with the challenges of biodiversity loss and climate change. In the fall of 2019, the UCRF received the North Star Award at the Green Carpet Fashion Awards during Milan Fashion Week.
Followers of the sustainable fashion movement believe that the fashion industry has a clear opportunity to act differently, pursuing profit and growth while also creating new value and deeper wealth for society and therefore for the world economy. They believe that clothing companies ought to place environmental, social, and ethical improvements on management's agenda. The goal of sustainable fashion is to create flourishing ecosystems and communities through its activity. This may include: increasing the value of local production and products; prolonging the lifecycle of materials; increasing the value of timeless garments; reducing the amount of waste; and to reducing the harm to the environment created as a result of production and consumption. Another of its aims can sometimes be seen to educate people to practice environmentally friendly consumption by promoting the "green consumer", which can allow for the company itself to gain more support and a larger following.
There are doubts within the movement as to the effectiveness of "green consumerism." Business models based on selling more units of clothing or accessories are widely not considered to be sustainable, regardless of how "eco-friendly" the garments themselves are. Thus the industry has to change its basic premise for profit, yet this is slow coming as it requires a large shift in business practices, models and tools for assessment. This became apparent in the discussions following the Burberry report of the brand burning unsold goods worth around £28.6m (about $37.8 million) in 2018, exposing not only overproduction and subsequent destruction of unsold stock as a normal business practice, but the behavior amongst brands that actively undermine a sustainable fashion agenda.
The challenge for making fashion more sustainable requires to rethink the whole system, and this call for action is in itself not new. The Union of Concerned Researchers in Fashion has argued that the industry is still discussing the same ideas as were originally mooted in the late 1980s and early 1990s. When taking the long view and examining fashion and sustainability progress since the 1990s, there are few actual advances in ecological terms. As the Union observes, "So far, the mission of sustainable fashion has been an utter failure and all small and incremental changes have been drowned by an explosive economy of extraction, consumption, waste and continuous labor abuse." 
A frequently asked question of those working in the area of sustainable fashion is whether the field itself is an oxymoron. This reflects the seemingly irreconcilable possibility of bringing together fashion (understood as constant change, and tied to business models based on continuous replacement of goods) and sustainability (understood as continuity and resourcefulness). The apparent paradox dissolves if fashion is seen more broadly, not only as a process aligned to expansionist business models, and consumption of new clothing, but instead as mechanism that leads to more engaged ways of living on a precious and changing earth.
In order to promote more sustainable forms of consumption, there are a multitude of emerging business models that challenge the prevalent ready-to-wear (ready-to-waste) model. Some of these go under the name of "circular fashion," inspired by the circular economy. While there are many models under development, some are gaining more traction. Much of the work on circular fashion builds on ideas and initiatives explored in the 1990s and onwards, by scholars such as Lynda Grose, Kate Fletcher, Rebecca Earley, Mathilda Tham and Timo Rissanen, especially the thinking around the "metabolism" of garments and wardrobes, "zero waste" production, and the focus on the whole life cycle of garments. The popular terminology around circular fashion, reached the mainstream through a report that has come to define the field, the 2017 "A New Textile Economy: Redesigning Fashion's Future" by the Ellen MacArthur foundation.
One model suggests a perspective emphasizing the "Power of Nature" which is the industry looking into materials that have always been looked at as waste as a more sustainable method to making new clothing. The materials that will mitigate negative impacts from the industry include vegan materials from the earth and recycling old fabric into new clothing.
Another models is based on "Rent a Closet"; this initiative has been around for a while. This trend ultimately lowers the new purchase of clothing and disposal of clothing, which means less waste. Rent the Runway is an example of the "Rent a Closet" trend. Rent the Runway started as a company that would give luxury brands like Hervé Leger, Vera Wang, Etro to people who may not be able to afford the clothing at regular retail price. Renting and sharing clothing is also known as CFC (collaborative fashion consumption) a sustainable fashion trend consumers are getting involved in.
Another trend is "Long Live Fashion" is the revival and recirculation of Vintage clothing. Vintage clothing is a way to lower the amount of clothing that gets disposed of and ends up in landfills. Companies like RE/DONE, Vintage Twin and Frankie Collective sell re-paired vintage clothing. Repairing and reselling clothing has less negative impact than creating new clothing does.
A more technically induced megatrend is "innovative recycling" which is looking at waste as value. The industry is starting to create incentives for consumers to participate in the recycling of clothing. Recycling doesn't only start here. The clothing stores themselves, can start to reinvent sustainable ways to properly waste their boxes and plastic bags. Some shopping malls even lack proper recycling bins, stores then do not properly separate their trash. This is a huge part of waste in "fast fashion" industries. Another example of this is in the packaging that the clothes come and are sent in from factories. Recreating this factor in fashion could greatly impact the amount of waste the industry creates. 
Using digital technologies and blockchain can promote more "Connected Clothes" which allows for more opportunities in digitalizing clothing for personalization, life-tracking, and traceability of its origin.
Tailored couture is argued could be one option for the future of a greener fashion industry, for those who can afford it, as it can potentially lead to less waste and more jobs improving the economy. Tailored couture is no longer desired because of the convenience of malls and stores provide but the consequence of the convenience is the pollution of the environment. The idea is that tailored clothing can reduce mass-production, while reusing and redesigning old clothes to fit could reduce the amount of old worn out unfitting clothes thrown out or given away.
Sustainable clothing refers to fabrics derived from eco-friendly resources, such as sustainably grown fiber crops or recycled materials. It also refers to how these fabrics are made. Historically, being environmentally conscious towards clothing meant (1), making clothes last long by caring for them, repairing and patching them, (2) inheriting and using hand-me-downs within ones expanded family and community, (3) buying clothes from thrift stores or any shops that sell second-hand clothing, or (4) donating used clothes to shops previously mentioned, for reuse or resale. In modern times, with a prominent trend towards sustainability and being ‘green’, sustainable clothing has expanded towards (5) reducing the amount of clothing overproduced, incinerated or discarded to landfills, and (6) decreasing the environmental impact of agro-chemicals in producing conventional fiber crops (e.g. cotton).
Under the accordance of sustainability, recycled clothing upholds the principle of the "Three R’s of the Environment": Reduce, Reuse, and Recycle, as well as the "Three Legs of Sustainability": Economics, Ecology, and Social Equity.
Through the utilization of recycled material for the manufacturing of clothing, provides an additional realm of economic world profit. Sustainable Clothing will provide a new market for additional job opportunities, the continuous net flow of money in the global economy, and the consumption reduction of raw materials and virgin resources. Source reduction or reducing the use of raw materials and virgin resources can ultimately reduce carbon emissions during the manufacturing process as well as the resources and carbon emissions that are related to the transportation process. This also prevents the unsustainable usage of extracting materials from the Earth by making use of what has already been used (i.e. recycling).
Recycled or reclaimed fibers are recovered from either pre or post-consumer sources. Those falling into the category of 'pre-consumer' are unworn/unused textile wastes from all the various stages of manufacture. Post-consumer textile waste could be any product that has been worn/used and has (typically) been discarded or donated to charities. Once sorted for quality and color, they can be shredded (pulled, UK, or picked, US) into a fibrous state. According to the specification and end-use, these fibers can be blended together or with 'new' fiber.
While most textiles can be recycled, in the main they are downgraded almost immediately into low-quality end-uses, such as filling materials. The limited range of recycled materials available reflects the market dominance of cheap virgin fibers and the lack of technological innovation in the recycling industry. For over 200 years recycling technology has stayed the same; fibers are extracted from used fabric by mechanically tearing the fabric apart using carding machines. The process breaks the fibers, producing much shorter lengths that tend to result in a low-quality yarn. Textiles made from synthetic fibers can also be recycled chemically in a process that involves breaking down the fiber at the molecular level and then repolymerizing the feedstock. While chemical recycling is more energy-intensive than mechanical pulling, the resulting fiber tends to be of more predictable quality. The most commonly available recycled synthetic fibre is polyester made from plastic bottles, although recycled nylon is also available
In addition to promoting a sounder environment by producing newer clothing made with sustainable, innovative materials, clothing can also be donated to charities, sold into consignment shops, or recycled into other materials. These methods reduce the amount of landfill space occupied by discarded clothes. According to the United States Environmental Protection Agency's 2008 Report on Municipal Solid Waste (MSW), Generation, Recycling, and Disposal in the United States defines clothing as non-durable – generally lasts less than three years – textiles. In 2008, approximately 8.78 millions of tons of textiles were generated, 1.45 millions of tons were recovered and saved from landfills resulting in a rate of almost 17%. The EPA report also states that the amount of MSW being "Discarded" is 54%, "Recovered" is 33%, and "Combusted with Energy recovery" is 13%. Approximately two-thirds of clothing materials are sent to landfills, making it the fastest-growing component of waste in the household waste stream. As of 2009[update], textiles disposed of in landfill sites have risen from 7% to 30% within the last five years.
Upcycling in fashion signifies the process of reusing the unwanted and discarded materials (ex. fabric scraps or clothes) into new materials or products without compromising the value and the quality of the used material. In order to implement the upcycling method, it is important to have an overview of the textile waste available because this is what dictates the garment that can be created. Using upcycling in fashion design emphasizes the importance of a local approach. Thus, both the input material (waste) and the production ideally should be local. Since levels of waste production and volumes of waste can differ by region, the first step to collecting materials for upcycling is to carry out a local textile waste study. The definition of textile waste can be production waste, pre-consumer waste, and post-consumer waste.
Typically, upcycling creates something new and better from the old, used or disposed of items. The process of upcycling requires a blend of factors like environmental awareness, creativity, innovation, and hard work and results in a unique sustainable product. Upcycling aims at the development of products truly sustainable, affordable, innovative, and creative. For example, downcycling produces cleaning rags from worn T-shirts, whereas upcycling recreates the shirts into a value-added product like a unique handmade braided rug.
Upcycling can be seen as one of the waste management strategies. There are different types of strategies. From least to most resource-intensive, the strategies are the reuse of product, repairing and reconditioning to keep products as long as possible, recycling the raw materials. The reuse of textile products 'as is' brings significant environmental savings. In the case of clothing, the energy used to collect, sort and resell second-hand garments in between 10 and 20 times less than that needed to make a new item.
It is meant to be innovative by making certain materials into something re-usable and improved, which gives companies and manufacturers higher values for their products. Recycling is a big factor in sustainability, so creating new materials to avoid mass pollution can help improve the economy. An example of a brand that does this is Ecoalf. All clothing items are made from recycled items like used tires and plastic bottles. The manufacturing of their items also takes place wherever the materials are recycled from, ultimately reducing their carbon footprint
The advantages of circular fashion include: reduced dependency on imported raw materials, creation of eco- friendly industries and jobs, eco-friendly brands benefit from a better public image, and reduction in environmental damage caused by resource extraction. On the other hand, disadvantages include dependency on the consumer's actions, creating a new business model on the basis of recycled is tough, and the entire cycle requires integrating product life cycle from raw material to disposal.
There are negative social and environmental impacts at all stages of the fashion product life: materials production and processing, manufacture of garments, retail and marketing, use and maintenance, and at the discard phase. For some products, the environmental impact can be greater at the use phase than material production, leading for instance to the suggestion to wash clothes less.
Consumer engagement challenges the "passive" mode of ready-to-wear fashion where consumers have few interfaces and little incentive to be active with their garments; to repair, change, update, swap, and learn from their wardrobe. This type of consumer engagement, aiming to promote fashion as an ability rather than primarily as a commodity, has been referred to as "fashion-ability." The term "folk fashion" has been used in the emphasis on craft engagements with garments where the community heritage of skills are in focus. There are currently many designers trying to find ways that experiment with new models of action that deposes passivity and indifference while preserving the positive social dynamics and sensibilities fashion offers, often in relation to Alvin Toffler's notion of the "prosumer" (portmanteau of producer and consumer). Notions of participatory design, open source fashion, and fashion hacktivism are parts of such endeavors, mixing techniques of dissemination with empowerment, reenechantment and Paulo Freire's "Pedagogy of the Oppressed." An example of such consumer engagement can be Giana Gonzalez and her project "Hacking Couture", which has tested such methods across the world since 2006. As highlighted in the research of Jennifer Ballie, there is also an increasing interest across industry to produce unique experiences amongst users, connecting co-design with social media apps and tools to enhance the user experience of consumers. A recent example has been the Open Source Fashion Cookbook, by the New York based brand ADIFF, showing how consumers can recycle materials, share and modify patterns, and co-create more engaging forms of fashion consumption.
Enhancing the lifespan of products have been yet another approach to sustainability, yet still only in its infancy. Upmarket brands have long supported the lifespan of their products through product-service systems, such as re-waxing of classic outdoor jackets, or repairs of expensive handbags, yet more accessible brands do still not offer even spare buttons in their garments. One such approach concerns emotionally durable design, yet with fashion's dependency on continuous updates, and consumer's desire to follow trends, there is a significant challenge to make garments last long through emotional attachment. As with memories, not all are pleasant, and thus a focus on emotional attachment can result in favoring a normative approach to what is considered a good enough memory to manifest emotionally in a garment. Cultural theorist Peter Stallybrass approaches this challenge in his essay on poverty, textile memory, and the coat of Karl Marx.
Main article: Clothing swap
Clothing swapping can further promote the reduction, reuse, and recycling of clothing. By reusing clothing that's already been made and recycling clothing from one owner to another, source reduction can be achieved. This moves away from usage of new raw materials to make more clothing available for consumption. Through the method of clothing swapping, an alternative resource for consumers to ultimately save in regards to money and time is provided. It reduces transportation emissions, costs, and the time it takes to drive and search through the chaos of most clothing stores. Swapping clothes further promotes the use of sustainable online shopping and the internet as well as an increase of social bonds through online communication or effective personal communication in "clothing swap parties." The EPA states, that by reusing items, at the source waste can be diverted from ending up in landfills because it delays or avoids that item's entry in the waste collection and disposal system.
Main article: Charitable organization
People can opt to donate clothing to charities. In the UK, a charity is a non-profit organization that is given special tax form and distinct legal status. A charity is "a foundation created to promote the public good". People donating clothing to charitable organizations in America are often eligible for tax deductions, albeit the donations are itemized.
Generally, charitable organizations often sell donated clothing rather than directly giving the clothing away. Charities keep 10% of donated clothing for their high quality and retail value for the thrift shops. Charities sell the rest of the donations to textile recycling businesses. While the recycling schemes of charitable organizations can be criticized for many reasons, some of the proceeds of the resale of garments goes to charitable causes and job-training, while the recycling initiatives of most brands simply goes to the profits of shareholders.
The following is a list of few charitable organizations known for accepting clothing donations.
There are "charities" that are actually for-profit organizations. These organizations are often multibillion-dollar firms that keep profits accrued from selling donated clothing. Monetary donations are given for public goodwill, but only at relatively few percentages. Such organizations often use drop-off boxes to collect clothes. These drop-off boxes look similar to their non-profit counterparts, which mislead the public into donating their clothes to them. Such public deception prompted backlash, one example where a mayor called for the city's removal of for-profit clothing donation bins. To search for reputable charities, see Charity Navigator's website.
Main article: Consignment
In layman’s terms, a clothing consignment shop sells clothes that are owned not by the shop’s owner but by the individual who had given (or consigned) the items to the shop for the owner to sell. The shop owner/seller is the consignee and the owner of the items is the consignor. Both the consignor and the consignee receive portions of the profit made from the item. However, the consignor will not be paid until the items are sold. Therefore, unlike donating clothing to charities, people who consign their clothes to shops can make a profit.
Main article: Textile recycling
According to an ABC News report, charities keep approximately 10% of all the donated clothing received. These clothes tend to be good quality, fashionable, and high valued fabrics that can easily be sold in charities’ thrift shops. Charities sell the other 90% of the clothing donations to textile recycling firms.
Textile recycling firms process about 70% of the donated clothing into industrial items such as rags or cleaning cloths. However, 20–25% of the second-hand clothing is sold into an international market. Where possible, used jeans collected from America, for example, are sold to low-income customers in Africa for modest prices, yet most end up in landfill as the average US sized customer is several sizes bigger than the global average.
There is a broad range of organisations purporting to support sustainable fashion, some representing particular stakeholders, some addressing particular issues, and some seeking to increase the visibility of the sustainable fashion movement. They also range from the local to global. It is important to examine the interests and priorities of the organizations.
There are many factors when considering the sustainability of a material. The renewability and source of a fiber, the process of how a raw fiber is turned into a textile, the impact of preparation and dyeing of the fibers, energy use in production and preparation, the working conditions of the people producing the materials, and the material's total carbon footprint, transportation between production plants, chemicals used to keep shipments fresh in containers, shipping to retail and consumer, how the material will be cared for and washed, the processes of repairs and updates, and what happens to it at the end of life. The indexing of the textile journeys is thus extremely complex. In sustainability, there is no such thing as a single-frame approach. Issues dealt with in single frames will almost by definition lead to unwanted and unforeseen effects elsewhere.
Overall, diversity in the overall fiber mix is needed; in 2013 cotton and polyester accounted for almost 85% of all fibers, and thus their impacts were, and continue to be, disproportionately magnified. Also, many fibers in the finished garments are mixed to acquire desired drape, flexibility or stretch, thus affecting both care and the possibility to recycle the material in the end.
Natural fibers are fibers which are found in nature and are not petroleum-based. Natural fibers can be categorized into two main groups, cellulose or plant fiber and protein or animal fiber. Uses of these fibers can be anything from buttons to eyewear such as sunglasses.
Other than cotton, the most common plant-based fiber, cellulose fibers include: jute, flax, hemp, ramie, abaca, bamboo (used for viscose), soy, corn, banana, pineapple, beechwood (used for rayon). Alternative fibers such as bamboo (in yarn) and hemp (of a variety that produces only a tiny amount of the psychoactive component found in cannabis) are coming into greater use in so-called eco-fashions.
Main article: Cotton
Cotton, also known as vegetable wool, is a major source of apparel fiber. Celebrated for its excellent absorbency, durability, and intrinsic softness, cotton accounts for over 50% of all clothing produced worldwide. This makes cotton the most widely used clothing fiber. Up to 1 billion people worldwide depend on the cotton industry for their livelihoods, including 100 million smallholder farmers.
Cotton is one of the most chemical-intensive crops in the world. Conventionally grown cotton uses approximately 25% of the world's insecticides and more than 10% of the world's pesticides. However, growing and processing this particular fiber crop is largely unsustainable. For every pound of cotton harvested, a farmer uses up 1/3 lb of chemical, synthetic fertilizer. As a whole, the US cotton production makes up 25% of all pesticides deployed in the United States. Worldwide, cotton takes up 2.4% of all arable lands yet requires 16% of the world's pesticides. The cotton hulls contain the most potent insecticide residues. They are often used as cattle feed, which means that consumers are purchasing meat containing a concentration of pesticides. The processing of cotton into usable fibers also adds to the burden on the environment. Manufacturers prefer cotton to be white so that cotton can easily be synthetically dyed to any shade of color. Natural cotton is actually beige-brown, and so during processing, manufacturers would add bleach and various other chemicals and heavy metal dyes to make cotton pure white. Formaldehyde resins would be added in as well to form "easy care" cotton fabric.
Main article: Bt cotton
To reduce the use of pesticides and other harmful chemicals, companies have produced genetically modified (GMO) cotton plants that are resistant to pest infestations. Among the GMO are cotton crops inserted with the Bt (Bacillus thuringiensis) gene. Bt cotton crops do not require insecticide applications. Insects that consume cotton containing Bt will stop feeding after a few hours, and die, leaving the cotton plants unharmed.
As a result of the use of Bt cotton, the cost of pesticide applications decreased between $25 and $65 per acre. Bt cotton crops yield 5% more cotton on average compared to traditional cotton crops. Bt crops also lower the price of cotton by 0.8 cents per pound.
However, there are concerns regarding Bt technology, mainly that insects will eventually develop resistance to the Bt strain. According to an article published in Science Daily, researchers have found that members from a cotton bollworm species, Helicoverpa zea, were Bt-resistant in some crop areas of Mississippi and Arkansas during 2003 and 2006. Fortunately, the vast majority of other agricultural pests remain susceptible to Bt.
Micha Peled's documentary exposé Bitter seeds on BT farming in India reveals the true impact of genetically modified cotton on India's farmers, with a suicide rate of over a quarter-million Bt cotton farmers since 1995 due to financial stress resulting from massive crop failure and the exorbitantly high price of Monsanto's proprietary BT seed. The film also refutes false claims purported by the biotech industry that Bt cotton requires less pesticide and empty promises of higher yields, as farmers discover the bitter truth that in reality, Bt cotton in fact requires a great deal more pesticide than organic cotton, and often suffer higher levels of infestation by Mealybug resulting in devastating crop losses, and extreme financial and psychological stress on cotton farmers. Due to the biotech seed monopoly in India, where Bt cotton seed has become the ubiquitous standard, and the organic seed has become absolutely unobtainable, thus coercing all cotton farmers into signing Bt cotton seed purchase agreements which enforce the intellectual property interests of the biotech multinational corporation Monsanto.
Main article: Organic cotton
Organic cotton is grown without the use of any genetic modification to the crops, without the use of any fertilizers, pesticides, and other synthetic agro-chemicals harmful to the land. All cotton marketed as organic in the United States is required to fulfill strict federal regulations regarding how the cotton is grown. This is done with a combination of innovation, science, and tradition in order to encourage a good quality of life and environment for all involved. Organic cotton uses 88% less water and 62% less energy than conventional cotton.
Main article: Naturally colored cotton
Cotton is naturally grown in a variety of colors. Typically, cotton color can come as mauve, red, yellow, and orange hues. The use of naturally colored cotton has long been historically suppressed, mainly due to the industrial revolution. Back then, it was much cheaper to have uniformly white cotton as a raw source for mass-producing cloth and fabric items. Currently, modern markets have revived a trend in using naturally colored cotton for its noted relevance in reducing harmful environmental impacts. One such example of markets opening to these cotton types would be Sally Fox and her Foxfiber business—naturally colored cotton that Fox has bred and marketed. On an additional note, naturally colored cotton is already colored, and thus do not require synthetic dyes during process. Furthermore, the color of fabrics made from naturally colored cotton does not become worn and fade away compared to synthetically dyed cotton fabrics.
Main article: Soy
Soy fabrics are derived from the hulls of soybeans—a manufacturing byproduct. Soy fabrics can be blended (i.e. 30%) or made entirely out of soy fibers. Soy clothing is largely biodegradable, so it has a minimal impact on environment and landfills. Although not as durable as cotton or hemp fabrics, soy clothing has a soft, elastic feel. Soy clothing is known as the vegetable cashmere for its light and silky sensation. Soy fabrics are moisture absorbent, anti-bacterial, and UV resistant. However, soy fabrics fell out of public knowledge during World War II, when rayon, nylon, and cotton sales rose sharply.
Main article: Hemp
Hemp, like bamboo, is considered a sustainable crop. It requires little water to grow, and it is resistant to most pests and diseases. The hemp plant's broad leaves shade out weeds and other plant competitors, and its deep taproot system allows it to draw moisture deep in the soil. Unlike cotton, many parts of the hemp plant have a use. Hemp seeds, for example, are processed into oil or food. Hemp fiber comes in two types: primary and secondary bast fibers. Hemp fibers are durable and are considered strong enough for construction uses. Compared to cotton fiber, hemp fiber is approximately 8 times the tensile strength and 4 times the durability.
Hemp fibers are traditionally coarse and have been historically used for ropes rather than for clothing. However, modern technology and breeding practices have made hemp fiber more pliable, softer, and finer.
Main article: Bamboo
Bamboo fabrics are made from heavily pulped bamboo grass. Making clothing and textile from bamboo is considered sustainable due to the lack of need for pesticides and agrochemicals. Naturally disease and pest resistant, bamboo is also fast growing. Compared to trees, certain varieties of bamboo can grow 1–4 inches long per day, and can even branch and expand outward because of its underground rhizomes. Like cotton fibers, bamboo fibers are naturally yellowish in color and are bleached white with chemicals during processing.
Main article: SCOBY
Burnished by a grant from the US. Environmental Protection Agency, associate professor Young-A Lee and her team are growing vats of gel-like film composed of cellulose fiber, a byproduct of the same symbiotic colonies of bacteria and yeast (abbreviated SCOBY) found in another of the world's popular "live culture" foods: kombucha. Once harvested and dried, the resulting material has a look and feel much like leather. The fibers are 100 percent biodegradable, they also foster a cradle-to-cradle cycle of reuse and regeneration that leaves behind virtually zero waste. However, this material takes a long time to grow about three to four weeks under lab-controlled conditions. Hence mass production is an issue. In addition, tests revealed that moisture absorption from the air softens this material makes it less durable. Researchers also discovered that cold conditions make it brittle.
Other alternative biodegradable fibers being developed by small companies include:
Protein fibers originate from animal sources and are made up of protein molecules. The basic elements in these protein molecules being carbon, hydrogen oxygen and nitrogen. Natural protein fibers include: wool, silk, angora, camel, alpaca, llama, vicuna, cashmere, and mohair.
Just as in cotton production, pesticides are conventionally used in the cultivation of wool, although quantities are considerably smaller and it is thought that good practices can significantly limit negative environmental impacts. Sheep are treated either with injectable insecticides, a pour-on preparation or dipped in a pesticide bath to control parasite infections, which if left untreated can have serious health implications for the flock. When managed badly, these pesticides can cause harm to human health and aquatic ecosystems both on the farm and in subsequent downstream processing.
Most commercially produced silk is of the cultivated variety and involves feeding the worms a carefully controlled diet of mulberry leaves grown under special conditions. Selected mulberry trees are grown to act as homes for the silkworms. The fibers are extracted by steaming to kill the silk moth chrysalis and then washed in hot water to degum the silk. The silk fiber is known for its strength and is considered a prestigious fiber. Its use in textiles is limited due to its high cost. Most silkworms used to produce silk are not harmed in the process and are grown in their natural habitat, essentially "free range". The silk industry also employs millions of people in rural China.
Cashmere is obtained from the fine, soft hairs of a cashmere goat's underbelly coat. This specific breed of goat is found throughout Asia. Due to the rarity of the breed, four goats are needed to produce enough cashmere for one sweater. Initially, cashmere was relatively expensive, but due to increased demand, the industry is beginning to take a toll on animals and the land. More and more goats are needed which results in more mouths to feed. Overpopulation of the goats degrades the land due to increased grazing. The cashmere industry is becoming more and more controversial with the questioning of the working conditions of goat herders and the underpaying of farmers. Oxfam reported in Spring 2021 on a project in Afghanistan being undertaken jointly with the Burberry Foundation and PUR Projet, working with goat farmers to improve their business operations and make the Afghan cashmere industry more sustainable.
Italian company Zero Grado Espace has developed MuSkin, an alternative to leather made from the cap of the phellinus ellipsoideus mushroom, a parasitic fungus that grows in subtropical forests. It is water repellent and contains natural penicillin substances which limit bacteria proliferation.
Wild Rubber, developed by Flavia Amadeu and Professor Floriano Pastore at the University of Brazil, is an initiative that promotes wild rubber material which comes from the sap or latex of the pará rubber tree that grows within a biodiverse ecosystem in the Amazon Rainforest, Acre, Brazil. It is tapped by local communities who typically have a close relationship the forest and will gather medicinal plants or wild food during their tapping rounds.
Qmilch GmbH, a German company has innovated a process to produce a textile fiber from casein in milk but it cannot be used for consumption. Qmilk fiber is made from 100% renewable resources. In addition, for the production of 1 kg of fiber Qmilch GmbH needs only 5 minutes and max. 2 liters of water. This implies a particular level of cost efficiency and ensures a minimum of CO2 emissions. Qmilk fiber is biodegradable and leaves no traces. In addition, it is naturally antibacterial, especially against the bacterial strains, Staphylococcus aureus and Pseudomonas aeruginosa and is ideal for people that suffer from textile allergies.
Fabrics made from Qmilk fiber provide high wearing comfort and a silky feel. The organic fiber is tested for harmful substances and dermatologically tested for the wearer's skin and body compatibility 0% chemical additives.
Manufactured fibers sit within three categories: Manufactured cellulosic fibers, manufactured synthetic fibers and manufactured protein fiber (azlon). Manufactured cellulosic fibers include modal, Lyocell (also known under the brand name Tencel), rayon/viscose made from bamboo, rayon/viscose made from wood and polylactic acid (PLA). Manufactured synthetic fibers include polyester, nylon, spandex, acrylic fiber, polyethylene and polypropylene (PP). Azlon is a manufactured protein fiber.
Main article: PET plastic
PET plastics are also known as Polyethylene terephthalate(PETE). PET's recycling code, the number within the three chasing arrows, is one. These plastics are usually beverage bottles (i.e. water, soda, and fruit juice bottles). According to the EPA, plastic accounts for 12% of the total amount of waste we produce. Recycling plastic reduces air, water, and ground pollution. Recycling is only the first step; investing and purchasing products manufactured from recycled materials is the next of many steps to living sustainably.
Clothing can be made from plastics. Seventy percent of plastic-derived fabrics come from polyester, and the type of polyester most used in fabrics is polyethylene terephthalate (PET). PET plastic clothing come from reused plastics, often recycled plastic bottles. The Coca-Cola Company, for example, created a "Drink2Wear" line of T-shirts made from recycled bottles. Generally, PET plastic clothing are made from recycled bottles as follows: plastic bottles are collected, compressed, baled, and shipped into processing facilities where they will be chopped into flakes, and melted into small white pellets. Then, the pellets are processed again, and spun into yarn-like fiber where it can be made into clothing. One main benefit of making clothes from recycled bottles is that it keep the bottles and other plastics from occupying landfill space. Another benefit is that it takes 30% less energy to make clothes from recycled plastics than from virgin polyesters.
Alexander Bismarck and Mitchell Jones from the University of Vienna have conducted research on the possibility of using fungal species to create sustainable leather alternatives. Leather alternatives can be produced by using byproducts of agricultural products such as sawdust. The sawdust acts as a feedstock for the growth of fungal mycelium. After a few weeks, the fungal bacteria can be processed and chemically treated into a leather-like material. The researchers state that these fungal biomasses exhibit similar material and tactile properties as authentic leather. Using fungal biomass to create a leather alternative is sustainable as the entire process is carbon neutral and all the materials are completely biodegradable when they are done being used. 
Whereas many producers have since the turn of the century been striving for a cradle-to-cradle model of production, or a circular economy, there has so far been no successful example of fully sustainable production, as there is environmental impact from all extractive production practices (in processes of material production, dying, assembly, accessorizing, shipping, retail, washing, recycling etc.) There are many small initiatives towards change, yet so far all these incremental improvements have been drowned by the explosive popularity of "fast" fashion and its economy of extraction, consumption, waste.
The global political economy and legal system supports a fashion system that enables fashion that has devastating environmental, social, cultural and economic impacts to be priced at a lower price than fashion which involves efforts to minimize harm in the growth, manufacturing, and shipping of the products. This results in higher prices for fashion made from reduced impact materials than clothing produced in a socially and environmentally damaging way (sometimes referred to as conventional methods).
Innovative fashion is being developed and made available to consumers at different levels of the fashion spectrum, from casual clothing to haute couture which has a reduced social and environmental impact at the materials and manufacture stages of production and celebrities, models, and designers have recently drawn attention to socially conscious and environmentally friendly fashion.
3D seamless knitting is a technology that allows an entire garment to be knit with no seams. This production method is considered a sustainable practice due to its reduction in waste and labor. By only using the necessary materials, the producers will be more efficient in their manufacturing process. This production method is similar to seamless knitting, although traditional seamless knitting requires stitching to complete the garment while 3D seamless knitting creates the entire garment, eliminating additional work. The garments are designed using 3D software unlike traditional flat patterns. Shima Seiki and Stoll are currently the two primary manufacturers of the technology. The technology is produced through the use of solar energy and they are selling to brands like Max Mara.
Zero-waste design is a concept that, although has been prevalent for many years, is increasingly being integrated into production. Zero-waste design is used through multiple industries but is very applicable in developing patterns for garments. The concept of zero-waste pattern making is designing the pattern for a garment so that when the textile is cut, there is no extra fabric going to waste. This means the pattern pieces for a garment fit together like puzzle pieces in order to use the entire amount of fabric provided, creating no waste in this step of production.
Traditional methods of dyeing textiles are incredibly harmful towards the earth's water supply, creating toxic chemicals that effect entire communities. An alternative to traditional water dyeing is scCO2 dyeing (super critical carbon dioxide). This process creates no waste by using 100% of the dyes, reducing energy by 60% with no auxiliary chemicals, and leaving a quarter of the physical footprint of traditional dyeing. Different names for this process are Drydye and Colordry. Another company called Colorep has patented Airdye, a similar process that they claim uses 95% less water and up to 86% less energy than traditional dyeing methods.
So far, no brand can label itself as fully sustainable, and controversies are abundant on exactly how to use the concept in relation to fashion, if it can be used at all, or if labels such "slow" and "sustainable" fashion are inherently an oxymoron. Brands that sell themselves as sustainable often still lack systems to deal with oversupply, take back used clothes, fully recycle fibers, offer repair services, or even support the life of the garment during use (such as instructions on washing, care and repair). Almost no brands offer spare parts, which says a lot about the general life expectancy of garments in general: brand are not supporting consumers to make garments last.
That said, some comparison websites (such as Rank A Brand, Good On You, ...) exist which compare fashion brands on their sustainability record, and these can at least give an indication to consumers.
There are much ecolabels in existence which focus on textile. Some notable ecolabels include:
Some brands that sell themselves as sustainable are listed below;
There is no certain stable model among the designers for how to be sustainable in practice, and the understanding of sustainability is always a process or a work-in-progress, and varies by who defines what is "sustainable;" farmers or animals, producers or consumers, managers or workers, local businesses or neighborhoods. Thus critical scholars would label much of the business-driven discourse on sustainability as "greenwashing" as under the current economic paradigm, "sustainability" is primarily defined as keeping the wheels of perpetual production and consumption turning; to keep the "perpetuum mobile" of fashion running and in perpetual motion.
There are some designers that experiment in making fashion more sustainable, with various degrees of impact;
A question at the foundation of sustainable fashion concerns exactly what is to be "sustained" of the current model of fashion. Controversies thus emerge what stakeholder agendas should be prioritized over others. There is also the associated concern of how to curb the practice of greenwashing on one hand, ad also ensure that firms that promote such practices are subject to increased scrutiny and criticism on the other.
A major controversy on sustainable fashion concerns how the "green" imperative is used as a cover-up for systemic labor exploitation, social exclusion and environmental degradation, what is generally labelled as greenwashing. Market-driven sustainability can only address sustainability to a certain degree as brands still need to sell more products in order to be profitable. Thus almost any initiative towards addressing ecological and social issues still contributes to the damage. In a 2017 report, the industry projects that the overall apparel consumption will rise by 63%, from 62 million tons today to 102 million tons in 2030, thus effectively erasing any environmental gains made by current initiatives. As long as the business models of fashion brands are based on growth as well as production and sales of high quantities of garment, almost all initiatives from the industry remain labelled as greenwashing.
Though organic cotton is considered a more sustainable choice for fabric, as it uses fewer pesticides and chemical fertilizers, it remains less than 1% global cotton production. Hurdles to growth include cost of hand labor for hand weeding, reduced yields in comparison to conventional cotton and absence of fiber commitments from brands to farmers before planting seed. The up front financial risks and costs are therefore shouldered by the farmers, many of whom struggle to compete with economies of scale of corporate farms.
Though some designers have marketed bamboo fiber, as an alternative to conventional cotton, citing that it absorbs greenhouse gases during its life cycle and grows quickly and plentifully without pesticides, the conversion of bamboo fiber to fabric is the same as rayon and is highly toxic. The FTC ruled that labeling of bamboo fiber should read "rayon from bamboo". Bamboo fabric can cause environmental harm in production due to the chemicals used to create a soft viscose from hard bamboo. Impacts regarding production of new materials make recycled, reclaimed, surplus, and vintage fabric arguably the most sustainable choice, as the raw material requires no agriculture and no manufacturing to produce. However, it must be noted that these are indicative of a system of production and consumption that creates excessive volumes of waste.
Used clothing is sold in more than 100 countries. In Tanzania, used clothing is sold at the mitumba (Swahili for "secondhand") markets. Most of the clothing is imported from the United States. However, there are concerns that trade in secondhand clothing in African countries decreases development of local industries even as it creates employment in these countries. While the reuse of materials brings resource savings, there are some concerns that the influx of cheap, second-hand clothing, particularly in Africa, has undermined indigenous textile industries. With the result that clothing collected in the West under the guise of 'charitable donations' could actually create more poverty. And the authors of Recycling of Low Grade Clothing Waste warn that in the long run, as prices and quality of new clothing continue to decline, the demand for used clothing will also diminish.
The increase in western consumers’ environmental interest is motivating companies to use sustainable and environmental arguments solely to increase sales. Because environmental and sustainability issues are complex, it is also easy to mislead consumers. Companies can use sustainability as a “marketing ploy” something that can be seen as greenwashing. Greenwashing is the deceptive use of an eco-agenda in marketing strategies. It refers mostly to corporations that make efforts to clean up their reputation because of social pressure or for the purpose of financial gain.
In the European Union, the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations required in 2007 that clothing manufacturers and importers identified and quantified the chemicals used in their products.
On May 3, 2012, the world's largest summit on fashion sustainability was held in Copenhagen, gathering more than 1,000 key stakeholders in the industry to discuss the importance of making the fashion industry sustainable. Copenhagen Fashion Summit has since then gathered thousands of people from the fashion industry in their effort to create a movement within the industry.
In July 2012, the Sustainable Apparel Coalition launched the Higg Index, a self-assessment standard designed to measure and promote sustainable supply chains in the apparel and footwear industries. Founded in 2011, the Sustainable Apparel Coalition is a nonprofit organisation whose members include brands producing apparel or footwear, retailers, industry affiliates and trade associations, the U.S. Environmental Protection Agency, academic institutions and environmental nonprofits. The Global Change Award, is an innovation challenge created by the H&M foundation. It created a trend report in 2017 to look at the future of sustainable fashion.
In 2019, the UK Parliament's Environment Audit Committee published a report and recommendations on the future of fashion sustainability, suggesting wide-ranging systemic change, not least government regulation and tax-incentives for sustainable practices, such as lowered VAT for repair services. As highlighted in the report, wide political and social changes are needed to push industry towards more sustainable practices and levels of consumption: brands doing "less harm" is not enough. The report finishes with the following statement:
"Retailers must take responsibility for the social and environmental cost of clothes. They should use their market power to demand higher environmental and labour standards from suppliers. Offering rental schemes, lifetime repair and providing the consumer with more information about the sourcing and true cost of clothing are all measures that can be more widely adopted. Shifting business practice in this way can not only improve a business’s environmental and social impact but also offer market advantage as they respond to the growing consumer demand for responsible, sustainable clothing."(p.54)
