THE CERTIFICATION DICTIONARY
When you're shopping online or in person, we're sure you've come across clothing tags that highlight various certifications. Sometimes it feels like there are so many certifications and buzzwords used on clothing labels that it can be hard to know what they all mean. To make it easier for the Cotina community to understand these certifications, we created this certification dictionary.
Everything here is alphabetized, and sources are linked for easy access in case you'd like to learn more. We hope this serves as a guide you can keep coming back to. This dictionary is also a living document; as we discover new certifications and important information, we'll continue growing and updating it over time.

B CORPORATION (B CORP)

B Corp Certification is a business certification that recognizes companies that meet social, environmental, and governance standards established by the B Lab. The B Lab Standards are intended to provide a global framework for measuring and improving business impact. These standards are developed by an independent advisory council that has representatives from around the world that have backgrounds in business, government, academia, and other fields.
Some of the key areas evaluated during the certification process include:
- Whether the company operates in an industry that aligns with B Lab's eligibility requirements
- The company's legal structure and accountability commitments
- Potential impacts on human rights and the environment
- The company's purpose, governance, and transparency practices
- Workplace quality, employee well-being, and inclusion
- The company's impact on communities and the environment
For a complete breakdown of the certification requirements and assessment criteria, you can download the full B Lab Standards documentation here.
bluesign

bluesign is described as a "system-based" certification. To acquire this certification, the production processes are evaluated by bluesign experts. These experts analyze every single phase in the product's journey; this means from the materials to the finished product.
Here are some examples of what the bluesign experts look for in their evaluation:
- Restricted and hazardous chemicals are managed and eliminated according to Bluesign criteria
- Materials and supply chains are traceable
- Emissions and wastewater are properly managed
- Energy and water are used efficiently
- Workers are protected from exposure to hazardous substances
- Facilities meet social responsibility requirements and follow applicable labor standards
The bluesign offical documentation can be found here here for more details
BSCI (BUSINESS SOCIAL COMPLIANCE INITIATIVE)

BSCI is essentially an auditing system (not a certification) that is managed by amfori, a global business association that helps companies improve and manage social responsibility within their supply chains.
The initiative allows companies to evaluate their suppliers to determine whether they are meeting established social and ethical standards.
To participate in BSCI audits, suppliers are expected to follow the amfori BSCI Code of Conduct. Some of the areas covered by this code include:
- Respecting worker rights
- Allowing workers to join trade unions
- Providing fair remuneration
- Ensuring healthy and safe working conditions
- Maintaining reasonable working hours
- Prohibiting forced labor
- Prohibiting child labor
- Implementing measures to reduce environmental harm
- Following ethical business practices, including anti-corruption measures
BSCI itself does not "certify" products or factories in the same way some other standards do. Instead, it provides a framework and auditing process to help companies assess and improve working conditions within their supply chains. So if you see BSCI referenced by a brand, it generally means the company is working to monitor and improve social conditions within its supply chain, rather than certifying a specific product.
CLIMATE NEUTRAL CERTIFIED / THE CLIMATE LABEL

Climate Neutral Certified (now transitioning to The Climate Label) is a certification that requires companies to measure their greenhouse gas emissions and invest in climate solutions based on their climate impact. To achieve certification, companies must account for emissions across their operations and supply chain and allocate funding toward projects that support the transition to a lower-emissions economy. In 2025, certified companies were required to allocate a minimum of $15 per tonne of emissions they produce through what is called a Climate Transition Budget.
What's really neat about this initiative is that you can see all the companies that have the Climate Neutral certification, and how much their emissions are here. You can also see how much money they are funding for climate solutions. For example, see Reformation's numbers here.
CRADLE TO CRADLE PRODUCTS INNOVATION INSTITUTE

Cradle to Cradle Certified sets standards for designers, brands, and manufacturers to ensure that high quality products are created with the planet and people in mind. The certification includes third-party verification to assess products against the Cradle to Cradle Certified standards.
These are the 5 pillars that this certification focuses on:
- Material Health: Recognizes that the chemicals and materials used in the product are safer for human health and the environment.
- Product Circularity: Evaluates whether a product was designed with its next life in mind. It looks at how easily a product can be reused, repaired, recycled, or composted and whether the company has systems in place to help keep materials out of landfills.
- Clean Air & Climate Protection: Evaluates how a company is working to reduce greenhouse gas emissions and increase renewable energy use.
- Water & Soil Stewardship: Considers whether the company is keeping the welfare of the water and soil resources in mind during production.
- Social Fairness: Evaluates whether the company respects human rights and promotes fair, safe, and equitable conditions for workers and communities.
The exact breakdown of the 5 pillars above can be found here.
EUROPEAN FLAX CERTIFICATION / MASTERS OF FLAX FIBRE™

The European Flax Certification is now being rebranded as the Masters of FLAX FIBRE™. The Masters of Flax FIBRE certification applies to Linen products, since Linen is exclusively made from the flax plant. This certification ensures that the European flax fibers used for the product are traceable; from the flax fiber to the finished product. The traceability is verified by Bureau Veritas Certification, an independent third-party organization.
For brands to use this certification for their products, 50% of their product needs to be made out of certified European origin flax fiber. Any flax fiber claimed under the certification must originate from certified European sources.
Here are some key requirements for this certification:
- The flax must be grown in Europe and be traceable from farm to finished product.
- Farmers use practices designed to reduce water use, and the flax is typically grown without irrigation.
- GMO flax seeds are not permitted.
- Farmers are encouraged to responsibly manage their use of fertilizers and pesticides.
- Farming practices that support soil health and biodiversity are encouraged.
- Workers must be employed in accordance with European labor laws.

FAIR TRADE CERTIFIED

The Fair Trade Certification focuses on ethical sourcing to help protect human rights and the environment. One of their goals is to enable sustainable livelihoods for farmers, fishers, and other workers involved in the supply chain of certified products.
There are multiple industries that can have their products Fair Trade Certified, such as coffee, florals, produce, seafood, and factories for example. For apparel products, Fair Trade Certified focuses on the factories where garments are made.
To be a Fair Trade Certified factory, it needs to be compliant with the Fair Trade USA's Factory Production Standard (FPS). These are the four focal impact areas for these standards:
- Worker Engagement: Workers must have opportunities to communicate with management, raise concerns without retaliation, and participate in decisions that affect their working conditions.
- Economic Development: Workers receive access to a Fair Trade Premium fund, which is an additional fund that workers collectively decide how to use for projects that benefit workers and their communities. For example, premium funds can be used for projects such as healthcare services, scholarships, transportation, childcare, meals, safety improvements, or other priorities chosen by workers.
- Social Responsibility: Factories must respect human rights, follow labor standards, provide safe working conditions, and comply with applicable labor laws.
- Environmental Responsibility: Factories are expected to reduce the environmental impacts of production by responsibly managing waste, chemicals, energy use, water use, and emissions.
