INFORMATION ABOUT CERTIFICATES AND SEALS
Certificates, Standards & Initiatives
Overview of all certificates
Global Organic Textile Standard (GOTS)
GOTS is a textile standard for products made from certified organic fibers. According to GOTS 8.0, the “organic” labeling grade requires a minimum content of 95% certified organic fibers; for “made with x% organic materials,” the minimum is 70%. The standard also includes requirements regarding processing, chemicals, and social criteria at the certified stages. Whether a specific finished product is GOTS-certified can be found directly on the respective item.
Global Recycled Standard (GRS)
The Global Recycled Standard (GRS) verifies the content of recycled materials in a product and tracks it through the supply chain. In addition, it sets requirements for chemical use, environmental management, and social criteria in certified facilities. For GRS-certified products, we state the recycled content on the item.
TENCEL™ Lyocell and LENZING™ ECOVERO™
TENCEL™ Lyocell and LENZING™ ECOVERO™ viscose are branded fibers from Lenzing AG. According to Lenzing, the wood used comes from controlled or certified sources. Which fiber and what percentage are contained in a specific product is indicated directly on the item.
Fair Wear Foundation (FWF)
The Fair Wear Foundation works with fashion brands to improve working conditions in garment factories. It does not issue a product label: brands become members, not individual items of clothing. If a brand in our range is a member, we state this alongside its products.
OEKO-TEX® STANDARD 100
OEKO-TEX® STANDARD 100 tests textiles for harmful substances. Product class I covers items for babies and toddlers up to 36 months and has the strictest limit values. The label applies to the specific item tested.
International Labour Organization (ILO)
The International Labour Organization (ILO) is a specialized agency of the United Nations. Its core labour standards, such as the prohibition of child and forced labour and the freedom of association, form the basis of our code of conduct for production partners. The ILO is not a seal.
Fairtrade Cotton
The FAIRTRADE Cotton Seal identifies cotton that has been grown and traded according to Fairtrade standards. Producer organizations receive the Fairtrade Minimum Price – or the higher market price – as well as an additional Fairtrade Premium for community projects. The seal refers to the cotton and not automatically to all subsequent production stages. In our range, products from MELA and Neutral®, for example, carry it.
Green Button
The Green Button is the German government's state-run textile seal. Two levels are audited: the company, to see whether it fulfills its due diligence obligations regarding human rights and the environment in the supply chain, and the product, via recognized seals such as GOTS or Fairtrade. In our range, for example, MELA carries it. GREEN SHIRTS itself is not certified with the Green Button.
B Corp
B Corp is a certification from B Lab for companies as a whole, not for products. Assessments cover governance, employees, community, environment, and customers. In our range, for example, tentree and Organic Basics are B Corp certified. GREEN SHIRTS itself is not B Corp certified.
We want to make it transparent what our clothing is made of and where it is produced. Our own designs are sewn in Bangladesh, India, and Turkey, and finished in Germany. For B2C shipments, we use packaging made of grass paper and cardboard. We only communicate information regarding recycled content if it is documented for the packaging material used.
Global standard for textiles made from organic fibers; audits the entire production chain, including chemical use and social criteria; label levels “organic” (min. 95% organic fibers) and “made with organic” (min. 70%).
2) “How to check a GOTS certificate”
Check the license number on the product or with the retailer and verify it in the public GOTS database (global-standard.org.
3) “GOTS at GREEN SHIRTS”
We are certified as a company under GOTS (CERES-1057). Whether an individual item is GOTS-certified is indicated on the respective product.
For our production partners, there is a code of conduct based on the ILO core labor standards. To date, not all partners have signed it. For GOTS-certified products, the GOTS social criteria apply in addition.
Our textiles are made from raw materials such as organic cotton, hemp, TENCEL™ Lyocell, or linen. We display which certificates a product has on the respective item – and only when they apply specifically to that exact product.
Production
Our GREEN SHIRTS proprietary models are sewn in Bangladesh, India, or Turkey, depending on the model, and finished in Germany. For other brands, the information provided on the respective product applies.
Printing process
Branding without compromise: We refine using environmentally conscious techniques, tailored to the motif, durability, and feel.
Materials
Timeless fabrics with a future: organic cotton, linen & hemp, TENCEL™ Lyocell, and recycled fibers. We select materials based on impact rather than trends – skin-friendly, robust, renewable.

Verifiable instead of nice-to-have: We work with recognized standards and display them transparently for each product.
