Certifications & Rankings for Sustainable & Ethical Fashion

At Wonena, every brand and product is carefully evaluated for its positive impact on the environment (Planet) and People (Diversity and Ethical Practice). We believe in supporting businesses that prioritize sustainability and ethical practices and are committed to showcasing these efforts through our curated catalog.

Globally recognized certifications and standards play a key role in assessing the impact of textile products. These certifications, backed by trusted organizations, use quantitative and qualitative measures to evaluate how products affect the planet and communities. They are continuously updated to reflect the latest scientific advancements and evolving trends in sustainability.

The brands that have invested time and resources to achieve these certifications lead the sustainable fashion movement. Their dedication deserves recognition, and we aim to honor their efforts by highlighting their achievements through our platform.

These certifications are a significant part of Wonena’s BIRDWATCHER indicator (How we validate our Brands). We value their transparency and global credibility, which help us ensure that our products align with our mission of promoting sustainability and ethical practices.

While we already showcase various certified products, we recognize that many more certifications and standards exist. As we expand our catalog, we are committed to transparency—asking the right questions about supply chain origins and material sourcing. We will continually update this page to highlight even more brands that positively impact the planet and people.

    Use of Certified Organic Fabrics through the Supply Chain

    GOTS (The Global Organic Textile Standard)

    The worldwide leading textile processing standard for organic fibers, including ecological and social criteria, is backed up by independent certification of the entire textile supply chain.

    A textile product carrying the GOTS label must contain a minimum of 70% certified organic fibers, and its label would say “made with organic materials.”
    A product carrying the ORGANIC label must contain a minimum of 95% certified organic fibers.

    Organic fibers are natural fibers grown without synthetic pesticides, herbicides, or GMOs (Genetically modified Organisms). This production process, called “Organic Agriculture,” sustains the health of ecosystems, soils, and people. For more information, visit their website: https://global-standard.org/

    Products free of harmful substances to human health

    OEKO-TEX Standard 100

    The most well-known and trusted certification worldwide for product safety is the Standard 100 label, in service since 1990 by OEKO-TEX Association, headquartered in Zürich (Switzerland).

    When a textile article (from yarn to finished product) carries the Standard 100 Label, it means that every component of this article has been tested for harmful substances and, therefore, is harmless for human health. Their process considers numerous substances that can be detrimental to human health. They are continuously investing in scientific development to update knowledge and statutory requirements.

    The OEKO-TEX® laboratory tests include around 100 test parameters and consider the intended use of the textiles. The more intensive the skin contact of a textile product, the stricter the limit values for each product class. For more information, visit their website: https://www.oeko-tex.com/en/our-standards
