The Ultimate Guide to Sustainable & Ethical Fashion Certifications

Blog, Eco-Fashion, Men's Fashion, Sustainability, Sustainable Fashion

Sustainable and ethical fashion is very important. But how do we know what we are getting is actually sourced this way? The intent to buy more sustainably-made clothing is the first step – ensuring it is in fact made this way is the next step. Trustworthy certifications can help us determine if a company is really committed to personal, environmental, and animal welfare, or if they are all talk and no action.

That is why we compiled a list of the most far-reaching, comprehensive, and actionable sustainable and ethical fashion certifications for clothing. These have been broken down into four categories: Environmental, Fair Labor, Holistic, and Membership Network Certifications. Each of these certifications are designed to encompass certain measurables and areas of focus.

Below you will find all of the organizations that we use at IndieGetup to ensure that the clothing we cover is made sustainably and with planet-animal-personal welfare in mind.

Environmental Certifications

One of the most pressing — and most important — areas of production that needs to be certified is the environmental impact. At a time when climate change concerns are growing and unsustainable materials, such as plastics, continue to increase, it is very important to address these issues.  The following certifications are focused primarily on environmental impact.


Global Organic Textile Standard (GOTS)

How it works: GOTS covers the processing, manufacturing, packaging, labeling, trading, and distribution of select textiles. These textiles must meet a certain set of environmental standards ( and be made from at least 70% certified organic natural fibers). GOTS also factors in social criteria in accordance with the International Labor Organization.

What is certified: Clothing, bedding, towels, fibres, raw fabrics — most textiles. (Check out their public database for more information.)

Where it is: Internationally in collaboration with organizations across the world.



How it works: OEKO-TEX offers several different certifications for different areas of clothing. The most common is Standard 100, which tests for substances like toxic chemicals that are harmful to humans. LEATHER STANDARD checks for toxic substances in leather, MADE IN GREEN looks for responsible and environmentally-friendly production processes, STeP checks supply chain friendliness, and DETOX TO ZERO measures the amount of water waste and sludge used in production.

What is certified: Raw materials, fabrics, and textiles as well as apparel, accessories, and home goods.
(Check out their certified products directory here.)

Where it is: Based in Switzerland but used all over the world.


Better Cotton Initiative (BCI)

How it works: BCI encourages more sustainable cotton sourcing through a defined set of standards. A BCU certification means the cotton sourced is at least 5% ‘Better Cotton’ (to begin, at least), with a plan to move to at least 50% ‘Better Cotton’ within five years.

What is certified: Cotton.

Where it is:  Also based in Switzerland (as well as the UK); certifications given globally.



How it works:  bluesign certification is given to textile manufacturers who are producing in a way that is safe for both humans and the environment, taking into consideration wastewater treatment, dye toxicity, worker and consumer safety, sustainable sourcing, and more.

What is certified: Anything made from textiles.

Where it is:  Also based in Switzerland and certified worldwide. 


Cradle to Cradle (C2C)

How it works: Cradle to Cradle is different, in a good way. Their Certified Product Standard focuses on the circularity of products rather than just the sourcing. It looks at a product through five categories: material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness. A product receives an achievement level (Basic, Bronze, Silver, Gold, or Platinum) in each category and its overall product label is whichever category has the lowest level.

What is certified: A lot: apparel, home goods, toys, furniture, cleaning supplies, building materials, and more.
(Check out C2C’s product registry here.)

Where it is: Based in California and Amsterdam. Found internationally.


Leather Working Group (LWG)

Membership Network Certifications

The following organizations are not true certifications (although you will see their labels on products), but rather a membership network.

These do not — though they are still valuable in their own way.
