STeP by OEKO-TEX®: the Impact Calculator

impact calulator step

Calculate your Carbon and Water Footprint

STeP by OEKO-TEX® facilities can measure and report their carbon emissions and water usage impact – at the facility level, by processing step or for 1kg of material. As part of its Roadmap to Excellence, the STeP by OEKO-TEX ® programme has developed a simple, user-friendly digital tool for facilities to calculate the Carbon and Water Footprint: THE IMPACT CALCULATOR.

The Impact Calculator provides production facilities an initial estimate and assessment on the materials and process steps that contribute most to their overall environmental impact. Participation is voluntary and will be available to any textile production facility applying for or already holding a STeP by OEKO-TEX® certification.


STANDARD 100 by OEKO-TEX® is a worldwide consistent, independent testing and certification system for raw, semi-finished, and finished textile products at all processing levels, as well as for accessories.

Articles that fall within the scope of STANDARD 100 by OEKO-TEX® certification include raw and dyed/finished yarns, woven and knitted fabrics, accessories, such as buttons, zip fasteners, sewing threads or labels, ready-made articles of various types, such as all kinds of garments, domestic and household textiles, bed linen and terry products.

Test criteria

Since its introduction in 1992, the STANDARD 100 by OEKO-TEX® has developed test criteria, limit values and test methods on a scientific basis. On the basis of its comprehensive and strict catalogue of measures, with several hundred regulated individual substances, the STANDARD 100 by OEKO-TEX® takes account of:

  • Important legal regulations, such as banned Azo colourants, formaldehyde, pentachlorophenol, cadmium, nickel, etc.
  • Numerous harmful chemicals, even if they are not yet legally regulated.
  • Requirements of Annexes XVII and XIV of the European Chemicals Regulation REACh as well as of the ECHA SVHC Candidate List insofar as they are assessed by expert groups of the OEKO-TEX® Association to be relevant for fabrics, textiles, garments or accessories. Discussions and developments that are considered to be relevant are taken into account as quickly and effectively as possible through updates to the STANDARD 100 by OEKO-TEX® requirements.
  • Requirements from the US Consumer Product Safety Improvement Act (CPSIA) regarding lead.
  • Numerous also environmentally relevant substance classes

OEKO-TEX® Standard 100 contributes to high and effective product safety from a consumer’s point of view. Test criteria and limit values in many cases go far beyond applicable national and international standards. Extensive product checks and regular company audits also ensure that the industry has a globally sustainable awareness of the responsible use of chemicals.

Recycled materials in STANDARD 100 by OEKO-TEX®

Recycled materials are difficult to certify. With their previous life, recycled materials are posing different challenges than regular virgin material. Therefore, within the STANDARD 100 by OEKO-TEX® framework these materials are treated differently.  

For the certification of recycled materials with STANDARD 100 by OEKO-TEX® different rules apply as for regular materials. If recycled is mentioned in the article scope the following basic rules apply: 

  • At least 20% of the main textile material needs to be recycled 
  • More information about the source of the materials is requested in the application 
  • An effective quality management system needs to be proven. This is needed to ensure a consistent product quality.
  • The testing program can differ compared to virgin material. While there is no chemical test whether a material is recycled or not, the varying source can lead to a higher testing frequency.  
  • A separate certificate from a virgin material is needed.  
  • Blends with virgin materials are allowed when they are necessary for the manufacturing of the material.   


Sustainable Textile Production (STeP) by OEKO-TEX® is a certification system for brands, retail companies and manufacturers from the textile chain who want to communicate their achievements regarding sustainable manufacturing processes to the public in a transparent, credible and clear manner.

Certification is possible for production facilities of all processing stages from fibre production, spinning mills, weaving mills, knitting mills to finishing facilities and manufacturers of ready-made textile items.

Through modular analysis of all relevant company areas such as management of chemicals, environmental performance, environmental management, occupational health and safety, social responsibility and quality management, the STeP certification allows a comprehensive and reliable analysis of the extent of sustainable management provided by a production facility.

STeP certified companies:


MADE IN GREEN by OEKO-TEX® is an independent textile label for highlighting consumer products and semi-finished products at all levels of the textile chain that are made from materials tested for harmful substances and that have been manufactured by using environmentally friendly processes and under safe and socially responsible working conditions.

Basically, any finished textile items and semi-finished products at all levels of the textile supply chain can be granted the MADE IN GREEN by OEKO-TEX® label, including all kinds of items of clothing and furnishings.

Added value for the consumer

The MADE IN GREEN by OEKO-TEX® label shows the consumer that the textiles concerned are tested for harmful substances and sustainably produced in accordance with OEKO-TEX® guidelines. 
Each item certified with the MADE IN GREEN label also features a unique product ID or QR code, which provides full traceability and transparency for the consumer. The labelling system gives them access to information regarding the production facilities along the textile chain in which the textile was produced, the stage of production in which the fabrics were employed and the countries in which the product was manufactured.


The MADE IN GREEN by OEKO-TEX® label is awarded for a period of one year and must then be issued again.

Company audits

Auditing of the participating production facilities is a vital part of each certification process.

Added value for industry and retail

Innovation leaders who want to promote new functions and features can use the label directly on their products to document and highlight the close partnerships they have with their suppliers to the outside world.

Reliable supplier relationships are often a key factor in the successful implementation of sustainable aspects such as product quality, regular education and training of employees and improving working conditions. The MADE IN GREEN label makes all of this visible to the consumer.

Companies who wish to make their entire supply chain transparent can use the MADE IN GREEN label as a trustworthy sign that their suppliers in countries such as China, India and Bangladesh also adhere to agreed quality standards and working ethics.

The MADE IN GREEN label provides information regarding the current sustainability of their entire supply chain. Companies can also use the designation to demonstrate continuous improvement as they work to achieve greater sustainability at their individual production sites.
