Eco certifications demystified
You need to know that the materials going into your garments have been sourced and manufactured in a safe, eco-friendly and ethical manner and these certifications are one way to ensure just that.
We’ve summarised the important details for the commonly used certifications for T-shirts and other garments.
ORGANIC STATUS
Many crops, including cotton, are often sprayed with pesticides during growth to prevent the crop from being damaged by pests like insects or bacteria, that would feed on the crop themselves.
Pesticides aren’t that specific though and affect other wildlife, including humans. They are concentrated up the food chain (e.g. the crop may be munched on by aphids, which are then eaten by insects, which are then eaten by birds, etc) and can affect many species, regardless of whether they even come into contact with the sprayed crop.
Pesticides also contaminate water sources and have been linked to respiratory illnesses and cancers. Particularly high amounts of pesticides are often used on cotton because it is not cropped for food.
For this reason, it is often dubbed the dirtiest crop, and cotton farmers are particularly hard hit. The UN estimates that 200,000 people die per year from toxic exposure to pesticides but the effects of chronic exposure and suicides from ill health affect many more.
In the UK there are three organic certifications that you are likely to see.
1. SOIL ASSOCIATION
The Soil Association is the UK’s leading organic certification body and they certify 70% of the organic market, from textiles to food, drink and beauty products. Global Organic Textile Standard (GOTS) and the Organic Content Standard (OCS) are the two organic textile standards that are valid in the UK and the Soil Association certifies to both schemes.
If a garment is certified by the Soil Association, it will automatically be certified GOTS and OCS and be able to carry all three standards.
Soil Association certification involves a fair bit of work, measuring and recording key performance indicators and keeping a very strict inventory of all organic vs. non organic stock although any eco-friendly business should be doing these things anyway. Soil Association certification costs around £1,500 per year, which means that small businesses may not be certified, even if they’re doing all the right things.

2. ORGANIC CONTENT STANDARD (OCS)
OCS certification shows that the garment has been made using organic fibres and this has been traced through the value chain from growth of the crop to the finished article. There are two types of certificate: OCS100 for 100% organic cotton and OCS blended for items that are blended with a non-organic fibre (often recycled polyester).

3. GLOBAL ORGANIC TEXTILE STANDARD (GOTS)
GOTS certification also covers the organic status of textiles, from harvesting of the raw materials and through the manufacturing process.
However it goes further to ensure that textiles are also processed in an eco-friendly and socially responsible manner. This means workers’ rights are protected, working conditions are safe and hygienic, only low impact dyes and inks are used, wastewater is treated properly, and energy and water use is monitored.
GOTS provides credible assurance to the end consumer that the garments have been manufactured in an environmentally and socially responsible way.
Only textile products that contain a minimum of 70% organic fibres can become GOTS certified. There are different certificates, depending on the percentage of organic fibres used, so a company might have a GOTS certificate covering those items that are 100% organic and then a GOTS 85 to cover those items with 85% organic content.
Accessories, such as labelling, tend to be plastic-based, but are considered during the certification process.

RECYCLED CONTENT
4. GLOBAL RECYCLED STANDARD (GRS)
GRS certification is for products with recycled content, where the recycled materials must be authenticated by the Textile Exchange, a non-profit organisation based in the US.
The GRS aims to provide brands with a tool for labelling but they also aim to encourage manufacturers to be innovative in the use of reclaimed materials, to establish more transparency in the supply chain, and to provide better information to consumers.
USE OF HARMFUL CHEMICALS
5. REACH
REACH is an EU regulation that was brought into effect in 2007 to help protect human health and the environment from harm by chemicals. REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals.
In summary, all chemicals used during manufacture must be declared, some chemicals are banned completely and, in the case of harmful chemicals, it must be shown that there are no alternatives that are more environmentally sound. All garments manufactured or sold in the EU must conform to REACH.
6. CONFIDENCE IN TEXTILES (OEKO-TEX 100)
If a product is labeled as Oeko-Tex certified it is considered free from harmful chemicals and safe for human use. To attain Oeko-Tex Standard 100 certification, the fabric has been tested and certified to be free from harmful levels of more than 100 substances known to be harmful to human health.
Harmful substances banned under the Oeko-Tex Standard 100 include:
- Specifically banned AZO dyes
- Carcinogenic and allergy inducing dyes
- Formaldehyde
- Pesticides
- Chlorinated phenols
- Chloro-organic benzenes and toluenes
- Extractable heavy metals
- pH value
- Phthalates in baby articles
- Emission of volatile components
- Odour
- Organotin compounds (TBT) and (DBT)
