Fashion is full of claims.
“Eco-friendly.”
“Ethical.”
“Responsible.”
But without clear standards behind them, these words don’t always mean much.
That’s where certifications come in.
Sustainable fashion certifications provide independent verification of how products are made, from raw materials through to manufacturing, chemical use and labour conditions.
If you want to make more informed choices, these are the labels worth knowing.
Best for: Organic fibres and full supply chain verification
GOTS is one of the most recognised certifications in fashion. It tracks organic fibres from farm to finished product and includes environmental and social criteria.
Why it matters
It covers both material integrity and working conditions, not just one or the other.
Best for: Chemical safety and skin contact
OEKO-TEX focuses on what’s in the fabric, testing for harmful substances that could affect human health.
Why it matters
It helps ensure clothing is safe to wear, especially for sensitive skin.
Best for: Ethical sourcing and fair wages
Fairtrade ensures producers are paid fairly and work under safe conditions.
Why it matters
It addresses inequality in global supply chains.
Best for: Recycled materials and traceability
GRS verifies recycled content and tracks it through the supply chain.
Why it matters
It ensures recycled claims are credible and not just marketing.
Best for: Animal welfare in wool
Ensures sheep are treated ethically and land is managed responsibly.
Best for: Ethical down and feather sourcing
Ensures animals are not subjected to unnecessary harm.
Best for: Chemical management and manufacturing impact
bluesign assesses the full production process, focusing on chemical use, water and worker safety.
Why it matters
It reduces harmful inputs before they reach the product.
Best for: Viscose, rayon and packaging materials
FSC and PEFC certifications ensure that forest-based materials are sourced from responsibly managed forests. This is particularly relevant for fabrics like viscose and modal, which are derived from wood pulp.
Best for: Labour conditions and worker rights
Focuses on fair treatment, wages and safe working environments.
Best for: Overall business impact
Assesses companies across governance, workers, environment and community.
Why it matters
It evaluates the entire business, not just individual products.
Best for: Product health and lifecycle impact
Global GreenTag is a product-level certification that assesses environmental and health impacts across a product’s lifecycle.
While not specific to fashion, it can apply to textiles, uniforms and materials used in clothing.
Why it matters
It helps verify lower-toxicity and lower-impact materials, adding another layer of transparency beyond traditional fashion certifications.
Certifications are designed to verify claims.
Instead of relying on marketing language, they provide:
Each certification focuses on a different part of the system, from materials to labour to chemical use.
Fashion is one of the most complex global industries.
Without certifications, it’s difficult to know:
Certifications reduce that uncertainty and help consumers make more informed decisions.
Understanding certifications is one step.
Sustainability Tracker helps connect those certifications to real brands and products, showing:
Because knowing the label is useful.
But understanding what it means in context is what drives better decisions.

Which fashion certifications matter most?
GOTS, OEKO-TEX, Fairtrade and GRS are among the most widely recognised, each covering different parts of the supply chain.
Does one certification cover everything?
No. Most certifications focus on specific areas such as materials, labour or chemicals.
Is Global GreenTag a fashion certification?
Global GreenTag is not fashion-specific but can apply to textiles and materials, assessing environmental and health impacts.
Are certified clothes more sustainable?
Certifications provide verified standards, making them more reliable than unverified claims, though impact still depends on the brand.
