In a sustainable fashion approach, fabric choice is essential. Beyond the fiber itself, another factor becomes decisive: certified fabrics in sustainable fashion.
With the growing number of marketing claims in the fashion industry, sustainable textile certifications help distinguish genuine commitments from simple greenwashing. They provide a clear framework verified by independent organizations and allow consumers to make more informed choices — for the planet and for human health.
What does “certified fabric” mean?
A certified fabric is a textile verified by an independent body according to specific criteria, which may include:
- environmental impact
- use of chemical substances
- raw material traceability
- social production standards
Sustainable textile certifications bring greater transparency to an industry that is often complex and difficult to navigate.

GOTS label: the reference for organic textiles
The GOTS certification (Global Organic Textile Standard) is considered one of the most demanding standards in organic textile production.
It guarantees:
- certified organic fibers
- strict restrictions on toxic chemicals
- compliance with social criteria across the supply chain
- full traceability from farm to finished product
A GOTS-certified garment covers the entire production chain — not only the raw material.
In sustainable fashion, GOTS is widely regarded as one of the most comprehensive textile certifications.
What about the BCI label?
Better Cotton Initiative (BCI) is neither an organic label nor a strict product certification. It is a sustainability initiative aimed at gradually improving conventional cotton farming practices.
Unlike GOTS, BCI does not prohibit GMOs, pesticides, or synthetic fertilizers. It encourages their reduction but does not fully exclude them.
Another important point: BCI operates under a “mass balance” system. This means that a garment labeled BCI does not necessarily physically contain BCI cotton. Brands purchase volumes of “Better Cotton,” which can then be mixed with conventional cotton within the supply chain.
BCI may represent progressive improvement on a large scale, but it is not equivalent to GOTS.
OEKO-TEX®: the global reference for harmful substances
The OEKO-TEX® Standard 100 certification is now the global benchmark for harmful substances in textiles.
Unlike GOTS, it does not certify that the fiber is organic. However, it guarantees that the final product does not contain harmful substances that could affect our health or the health of workers involved in its production.
Each component of the garment — fabric, threads, dyes, buttons — is tested according to very strict limits.
OEKO-TEX® therefore provides strong health protection, particularly for:
- sensitive skin
- garments worn directly on the skin
- children's clothing

FSC and PEFC: references for wood-based fibers
FSC and PEFC certifications apply to fibers made from wood (such as TENCEL™, Modal, or certain types of viscose).
They guarantee that the wood used comes from responsibly managed forests that respect:
- biodiversity
- ecosystems
- local communities
FSC and PEFC are important indicators of traceability and responsible forest resource management. In sustainable fashion, FSC and PEFC are key references to ensure wood traceability, regulate forest management, and contribute to the fight against deforestation.
Other useful textile certifications (brief overview)
There are other relevant sustainable textile certifications depending on the material and commitment level.
GRS (Global Recycled Standard)
GRS is a certification dedicated to recycled materials. It guarantees a minimum percentage of recycled content in the product and ensures traceability throughout the supply chain.
It also includes environmental and social criteria related to certain production practices, as well as restrictions on chemical use.
RWS (Responsible Wool Standard)
RWS aims to regulate wool production by integrating criteria related to animal welfare and responsible land management.
The label also ensures traceability of wool from farm to finished product, helping identify more regulated supply chains for responsible wool production.
Fairtrade
The Fairtrade label focuses on social and economic production conditions. It guarantees:
- fairer wages for producers
- regulated working conditions
- development premiums for local communities
In textiles, it mainly concerns raw materials such as cotton. Fairtrade does not address the environmental criteria of the final product but rather the social and economic aspects of the supply chain.
Why certified fabrics are essential in sustainable fashion
Choosing certified fabrics in sustainable fashion means:
- reducing risks linked to harmful substances (especially with OEKO-TEX®)
- supporting more regulated and transparent supply chains
- making more informed choices beyond marketing claims
- encouraging better practices within the textile industry
Recognizing a truly certified garment means identifying the official logo, checking for a certification number or traceable reference, and understanding clearly what the label actually covers.
Labels do not make a garment “perfect,” but they remain reliable benchmarks for comparison and better understanding what we buy.
In a sustainable fashion approach, choosing certified fabrics and sustainable textile certifications brings greater clarity — for the planet, for our skin, and for a more transparent textile industry.
