Apparently Good Housekeeping now has a green seal of approval. UL laboratories, the safety test lab, also has it’s own green seal of approval. In fact, according to the new 2009 Conscious Consumer Report from BBMG, there are now over 400 different certifications related to “green” and environmental attributes of products and services. So many that such marks risk losing their effectiveness. Steven Colbert said that they now had a “Green Colbert Report” – they’re reducing their emissions by jumping on the bandwagon.
And like all comedy, it only hurts when we laugh. Since we’re all about textiles, let’s focus here. Do you even know what certifications pertain to textiles?
The market is absolutely rife with claims about organic cotton – and believe me, I have absolutely nothing against organic cotton. But the focus (by marketers and consumers alike) is that if it’s made of organic cotton, then the product is sustainable. That’s far from the truth. We like to use the analogy of “organic applesauce” – that is, if you take organic apples, then cook them with preservatives, emulsifiers, Red Dye #2, stabilizers and any number of other additives – do you end up with organic applesauce? Just like bread – which is made from wheat which is grown (maybe organically), harvested, ground into flour, mixed with milk, yeast, salt and maybe other things, then baked – fabric undergoes the same type of transformation. I mean, really, do you actually think that the cotton boll which you see in the picture is transformed into your blouse without some kind of serious work? What about oil? Think of crude oil and and your new sheets – what do you think has to have happened to that crude to make it acceptable for your bedroom?
So the certifications which are often used for fabrics have only to do with the FIBER, and not with the processing. The processing is environmentally damaging and results in fabric that contains many chemicals that seriously jeopardize our health. And often a product is advertised as being an “organic fabric” when what they mean is the fabric started out with organic fibers – but the processing, like the organic applesauce mentioned above, results in fabric that contains a high proportion, by weight, of synthetic chemicals (such as lead or mercury, formaldehyde, chlorine, or phthalates).
Besides the proliferation of certifications, further muddying of the waters happens because some of the certification agencies which can certify fabric ALSO certify fiber. In other words, each end product can be certified. So if we deconstruct a piece of fabric, we can have certification at each stage: (1) growing and harvesting of organic fibers (2) ginning or other preparation of the fibers to make them suitable for use in spinning; (3) spinning of the fibers into yarns; (4) weaving of the yarns into fabric and (5) final product (i.e., blouse, tablecloth, etc.). Makes you dizzy doesn’t it?
It’s quite common to find “organic cotton” fabrics in the market – in other words, fabrics made of organic fibers. Or at least, the claim is that the fibers are organic. Unless they are certified organic fibers, the claim is meaningless: there are no standards for calling a natural fiber “organic” since by definition they are organic – because the definition of “organic” is “of, relating to, or derived from living organisms.” There is a big difference between a fabric or product which claims to be “organic” and one that claims to be “certified organic”. So it is important to look for the certification and ask who certified the fibers (if they don’t display that information). Believe me, if a company has gone to the trouble and expense of certifying their fibers, they will definitely have the information of who did the certification!
Common certification agencies for fibers include:
- United States Department of Agriculture, National Organic Program
- Soil Association Certification Limited (SA Certification) is the UK’s largest organic certification body. It’s also the only certification body linked to a committed charity, promoting organic food and farming.
- OneCert: OneCert provides organic certification worldwide. Certification and inspection programs include the US National Organic Program (NOP), European Organic Regulations (EU 2092/91), Quebec Organic Standards (CAQ), Japan Agricultural Standards (JAS), IFOAM, and Bio Suisse. Services include organic certification, organic inspection, export certificates, transaction certificates, on-line record keeping, answers to certification questions, and presentations of organic topics.
- Control Union (Skal): Control Union is a global one-stop-shop for a range of certification programs, including organic fibers. It certifies to the standards of
- AB logo
- Bio Suisse
- Canada Organic Regime
- EU organic
- Japanese Agricultural Standards
- Naturland inspections
- Polish EU organic
- The Institute for Marketcology (IMO): IMO is one of the first and most renowned international agencies for inspection, certification and quality assurance of eco-friendly products. Its world-wide activities are accredited by the Swiss Accreditation Service (SAS) according to EN 45011 (ISO 65), which is the international standard for certification. IMO offers certification for organic production and handling according to the European Regulation (EU) Nr. 2092/91.
The certifications above verify that the fibers have been grown and harvested to organic standards set forth by the various standards. But they do not deal in any way with the processing of the fibers into fabric.
There exist several third party certifications which we think every conscious consumer of fabric should be aware. We should all know what the certification does – and doesn’t – cover: Oeko-Tex, GOTS, C2C, GreenGuard, Global Recycle Standard and SMART.
Before giving a summary of the main points of each of the certifications which deal with fiber processing (i.e., weaving), it’s important to note that these certifications are all in business – it costs money to achieve the certification – sometimes it costs a LOT of money. Like organic designations in food, some farmers, for example, grow hemp sustainably (because they can). But because there isn’t a robust market yet for hemp they don’t want to spend the money for the certification to show it as organic. Cradle to Cradle and GreenGuard can cost up to $30,000 per product for certification, so when you look on the web sites for these certifications, you see only large, well established companies who can afford to pay the certification costs. In addition to these certifications, there are many new “green guides” on the internet which purport to list green products. A basic listing may be free, but any additional bells and whistles costs money. So prominently featured green products may be specially featured because the manufacturer has paid for the spotlight.
List of certifications:
GreenGuard (www.greenguard.org). GreenGuard is not designed specifically for fabrics, but it is often advertised that a fabric is GreenGuard certified. GreenGuard has developed proprietary indoor air-quality pollutant guidelines based on government and industrial bodies. Those products that pay the testing fee and pass muster earn the right to call themselves GreenGuard certified. It was launched in 2000 by Atlanta-based for profit Air Quality Sciences (AQS), which is now a separate not for profit organization.
GreenGuard tests for the emitting chemicals coming from a product; that means it tests only for evaporating chemicals, chemicals which are a gas at room temperature. And that is all GreenGuard does – it does not look at the production of the fabric, or any social justice issues nor does it look at carbon footprint.
And GreenGuard, by measuring only emitting chemicals, is significant for what it does not measure:
- It does not measure any of the heavy metals (lead, mercury, copper, etc.)
- It does not measure PVC, which is a polymer and therefore not volatile
- It does not measure phthalates (except in the Children and Schools certification); phthalates are semi volatile, and don’t begin to evaporate until approximately 7 days after exposure to the air.
Oeko Tex (www.oeko-tex.com): founded to provide an objective and reliable product label for consumers and a uniform safety standard for the assessment of harmful substances in fabrics. Its aim is to ensure products are free of harmful substances.
The Oeko-Tex Standard 100 excludes harmful substances or limits their use. The following parameters form part of the Oeko-Tex list of criteria:
- AZO dyes*
- Carcinogenic and allergy-inducing dyes
- Chlorinated phenols
- Chloro-organic benzenes and toluenes
- Extractable heavy metals
- Phthalates* in baby articles
- Organotin compounds (TBT and DBT
- Emissions of volatile components
Biologically active products and flame-retardant products are regulated separately. Oeko Tex is a registered trademark. Make sure that the test number is quoted and the test institute is named as shown on the logo above.
This certification does not look at the processing or manufacturing (whether wastewater is treated, for example, or renewable energy is used to power the mill) – it is solely concerned with the final product. There are also no social requirements.
Cradle to Cradle (www.c2ccertified.com) : primarily it certifies that the product uses environmentally safe and healthy materials – however the list of what is considered safe is proprietary so we have to take their word for it. In other words: they’re not transparent. C2C certifies just the product, without looking at how it is installed or used. It has an energy, water and social responsibility component.
Cradle to Cradle’s strength is in material chemistry. All ingredients in a product are identified down to 100 parts per million (ppm) and assessed according to 19 human and environmental health criteria:
|C2C Human and Environmental Health Criteria|
|Human Health:||Environmental Health|
|Endocrine Disruption||Algae Toxicity|
|Reproductive Toxicity||Persistence/ Biodegradation|
|Acute Toxicity||Ozone Depletion/ Climatic Relevance|
|Chronic Toxicity||Material Class Criteria|
|Irritation||Content of Organohalogens|
|Sensitization||Content of Heavy Metals|
All ingredients are rated: green, yellow, red (which has been ascertained to be toxic) or grey (incomplete data, handled like a red). To achieve Gold and Platinum levels, a product cannot contain any ingredients classified as RED – unless there are no existing substitutes. MBDC developed this database and it is not available to outsiders.
All ingredients are classified as either a technical or biological nutrient: published C2C literature doesn’t define “recyclable” or “compostable” but MBDC uses European Union guidelines for biodegradability, and Federal Trade Commission (FTC) guidelines for recyclability. FTC guidelines require an established recycling pathway.
For the energy component, it focuses on the manufacturer’s use of renewable energy in production. Manufacturers need to use renewable energy for the product’s manufacture to achieve Gold certification, and for the energy used in the product’s entire supply chain to achieve Platinum. Renewable energy may be purchased on site or purchased thru energy credits.
Certification requires that companies work to preserve the quality and supply of water resources; implementation of these guidelines is required for Platinum.
Manufacturers must adopt corporate ethics and fair labor statements
However, it’s easy to confuse the ideals and philosophy of the founders with the actual requirements for certification. For example, a C2C Silver doesn’t guarantee that a product is free of all red ingredients; the only “knockout” chemical at Silver is PVC. There is no report card for consumers that details what a certified product does or does not include.
In addition, nutrients may not be returned to technical or biological cycles as described: the minimum requirement for certification is that a product be 67% recyclable or biodegradeable. But even a 100% recyclable product may not be able to return to either the technical or biological nutrient cycle.
MBDC certifies just the product, without looking at how it is installed or used. HYCRETE (an additive to make concrete waterproof) is an example of how misleading this can be – when used as intended, HYCRETE is not biodegradeable and cannot be recycled by any established process. Yet the product can degrade – if you accidentally spill a five gallon bucket into a local stream, it’s going to degrade and isn’t going to do any harm. Yet if used as intended it can neither biodegrade nor be recycled.
C2C criteria does not refer to manufacturing byproducts or the waste and energy use associated with resource extraction (such as is the case with polyester). Also the energy and water use standards focus on manufacturing, leaving out the energy and water consumption that results from use of the product.
EXAMPLE: Kynar (coating on Formawall panels): uses fluoropolymer in mfring process which releases PFOA (bioaccumulative and likely carcinogen). But the PFOA slips thru the C2C assessment since it’s not a product ingredient.
Finally, some say that C2C is not true third party certification, but rather a second party program since MBDCs primary business is consulting with manufacturers,
IN SUMMARY: C2C is distinguished by inspiring ecological thinking, affiliation with respected thought leaders and idealism. But it is complicated by a lack of transparency and gaps in underlying criteria; lack of boundaries between the C2C standards developing body, C2C certification body and the MBDC consulting body.
They’re revising it now, but historically they have not looked at carbon footprint.
For more on C2C, see the article “Cradle to Cradle Certification: A Peek Inside MBDC’s Black Box”, which appeared in Environmental Building News, February 2007
The Global Organic Textile Standard (GOTS) ( http://www.global-standard.com; see also: www.organic-textile-services.com) is a collaborative effort between the United States Organic Trade Association, Soil Association, International Association Natural Textile Industry (IVN) and Japan Organic Cotton Association (JOCA) to codify textile standards so consumers and manufacturers have one certification – an important step toward harmonization and transparency in textile labels. Since work began on codifying the Global Organic Textile Standard (GOTS) in 2002, it has evolved into the leading set of criteria in the field of organic textile processing.
GOTS aims to define a universal standard for organic fibers—from harvesting the raw materials, through environmentally and socially responsible manufacturing, to labeling—in order to provide credible assurance to consumers. Standards apply to fiber products, yarns, fabrics and clothes and cover the production, processing, manufacturing, packaging, labeling, exportation, importation and distribution of all natural fiber products, GOTS provides a continuous quality control and certification system from field to shelf. There are also social responsibility components (i.e., fair wages, no forced or bonded labor, etc.) All parameters are listed and accessible. The GOTS parameters for materials include prohibitions or restrictions on:
- Aromatic solvents
- Chloro Phenols (TCP, PCP)
- Complexing agents (APEO)
- Formaldehyde and short chain aldehydes
- Fungicides and biocides
- Halogenated solvents
- Heavy metals
- Ammonia treatment
There are detailed social criteria: no forced or bonded labor; workers are not required to lodge “deposits” or identity papers with employer; no child labor; workers are free to leave after reasonable notice; working conditions are safe and hygenic.
Wastewater treatment includes measurement and monitoring sediment quantities, waste water temperature and waste water pH. Wastewater from wet-processing sites (except greasy wool scouring sites and flax retting sites) must, when discharged to surface waters after treatment, have a COD content of less than 25 g/kg of textile output expressed as an annual average. If the effluent is treated on site and discharged directly to surface waters, it must also have an pH between 6 and 9 (unless the pH of the receiving water is outside this range) and a temperature of less than 40C° (unless the temperature of the receiving water is above this value). The COD/BOD ratio must be ≤ 5. The copper content must not exceed 0,5 mg/l.
The GOTS certification applies to only natural fibers, it cannot be applied to polyester or other synthetic fibers.
SMaRT Sustainable Products Standard (www.sustainableproducts.com): based on transparency, using consensus based metrics and life-cycle analysis. They also have in place rules which prevent industry trade association dominance so they can move substantially beyond the status quo. Renewable energy and conventional energy reduction are specified.
Environmental, social and economic performance criteria are defined and quantified In areas such as:
- Acid Rain
- Climate change
- Habitat alteration
- Ozone depletion
- Fossil fuel depletion
- Criteria and indoor air pollutants
- Water pollutants water intake
- Solid and hazardous waste
The Sustainable Textile Standard incorporates procedures and protocols established in the following sustainability standards, thereby eliminating both redundancies and potential inconsistencies:
- Global Reporting Initiative (GRI) Social Indicators http://www.globalreporting.org/GRIGuidelines/index.htm
- Stockholm Toxic Chemicals List http://www.chem.unep.ch/publications.htm
- Life Cycle Assessment (LCA) ISO General Principles Standard http://www.iso.ch/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=23151
- General Product Life Cycle Diagram (Figure 1, p. 15)
- Federal Trade Commission Environmental Marketing Guides http://www.ftc.gov/bcp/conline/pubs/buspubs/greenguides.htm
- US Green Building Council LEED Rating System http://www.usgbc.org/LEED/existing/leed_existing.asp
- FSC Certified Wood Practices http://www.certifiedwood.org/
- Green-e Power http://www.resource-solutions.org/Green-epage.htm
SMART has a certification specifically for textiles called the Smart Sustainable Textile Standard. For textiles it requires 1300 chemicals be tracked and addressed; it is also transparent (i.e., nothing is proprietary or hidden in their requirements or in decision making). Confers multiple achievement levels.
The Global Recycle Standard (www.certification.controlunion.com): This brand new standard was developed to help verify claims regarding recycled products. The Gold level requires products to contain 95 – 100% recycled material; Silver requires 70 – 95% and Bronze contains a minimum of 30%. The definition of “recycled” under this standard is based on criteria already laid down by Scientific Certification Systems. In addition, the standard contains environmental processing criteria and strick raw material specification (water treatment and chemical use is based on GOTS and Oeko-Tex 100) and social responsibility is incorporated – which ensures workers health and safety and upholds workers rights in accordance with International Labor Organisation (ILO) criteria.
10 thoughts on “Certifications – what to look for in textiles”
First, let me share my enthusiasm for our mutual embrace of the philosophy of making the world a safer place. We at Hycrete are passionate about this.
However, I do want to point out that it is inaccurate to state that Hycrete, used as intended by dosing into concrete, cannot be recycled.
In fact, dramatically the reverse is true. The use of Hycrete in concrete eliminates the need for the use of external “membrane” waterproofing systems, typically fabricated from asphaltic or other environmentally unfriendly substances. That alone is a positive benefit.
In addition, consider this – concrete with adhered membranes is impractical (or illegal) to recycle. Through use of Hycrete, that concrete becomes recyclable. This is an important benefit of the product, and one which it is marketed specifically for. So, not only is “applied Hycrete” recyclable, but it eliminates non-recyclables and makes a vastly larger volume product – concrete – recyclable, as well.
The combination of these benefits has been recognized by the US Green Building Council, which has awarded a LEED Innovation Credit for “Membrane-Free Construction”.
If there is a use of Hycrete perceived by the authors of this blog that does not fit this benefit, members of Hycrete’s management team would be happy to discuss further. However, as it stands, this post is technically inaccurate, misleading, and positioned to do greater damage to the construction sustainability effort through its lack of understanding of concrete processes. May I respectfully request either a dialog or a retraction?
Hi Aaron: I appreciate your comment, and apologize for any misinformation I might have been contributing to! I was using examples to clarify a point about the way the certifications work, and I should have made it clear that I was simply referencing the special report that appeared in the February 2007 issue of Environmental Building News (Cradle to Cradle Certification: A Peek Inside MBDC’s Black Box) which quoted Jay Bolus, MBDC’s executive vice president for certification, who used Hycrete as an example of the MBDC tendency to certify just the product, without looking at how it is installed or used. His statement in that article was “Hycrete, an additive designed to waterproof concrete (see EBN Vol 15, No. 12), is not biodegradeable and cannot be recycled by any established process. In practice, then C2C’s certification of Hycrete as a biological nutrient means that “if you accidentally spill a five-gallon bucket into a local stream, it’s going to degrade and isn’t going to do any harm.”
I suggest that you contact MBDC and EBN as to the statements made in their article – I admit that I know nothing about concrete.
Forgive me – I failed to introduce myself. I am a Vice President at Hycrete:)
And I forgot to say that if you want to clarify points that might have been addressed in the two years since this article appeared and/or to clarify your position, I’d be glad to post that. We’re all in this together and I appreciate your steps to helping make the building industry safer and better for our planet.
Thanks for your consideration.
Since the content of the article does tend to mislead an audience about the positive environmental impact of Hycrete, I would certainly appreciate some added posting.
I’d request using the meat of my original reply, plus a header to the effect of: “Of important note, often-times the positive impact of a material is in what it accomplishes indirectly. While Hycrete is certainly a low-impact material to begin with, it’s net end effect has a much larger benefit.”
Let me know if you’d like us to fully craft it for you.
Hi Aaron: I would very much appreciate your crafting the wording as I’m not, as I said, knowledgeable about concrete. Thanks so much. Leigh Anne

I’m just grateful that you’re going to the trouble of publishing – and engaging in civilized discussion
nothing’s ever going to be perfect [eg even if that organic tomato was transported to the farmer’s market on a bicycle; the bicycle was still made from processed resources in a factory somewhere]
Australian manufacturers have a particular challenge ahead of them in attempting supply chain monitoring and transparency…as our industries have mostly gone offshore to Asia.
as you say labels proclaiming ‘organic’ are out there in abundance, but who knows where they’ve really been.
Hi there- Another important player is Scientific Certification Systems, a pioneer in environmental certification. With 25 years of experience in the field, SCS authored the recycling standard on which the Global Recycling Standard is based, and currently audits and certifies to that standard. SCS also provides indoor air quality certification for fibers (such as wallcoverings or upholstery) with its SCS Indoor Advantage label.
Leigh Anne, You sure know your stuff (and have educated readers to help fill in any gaps). I wonder if you have thoughts on social certifications related to textiles. Particularly I am interested in experiences, analysis of those concerned with wage, labor and community investment practices through Fair Trade. Any thoughts welcome as I try to navigate not just the world of Fair Trade (which I am familiar with) but also the complexities of the textile industry, labor concerns, etc.
Hi Jackie: I’m glad you’re bringing this up because the textile industry has not exactly been the poster child for advances in fair labor standards by any means. The new Global Organic Textile Standard (GOTS) has a relatively extensive social justice component, as does the new Oeko Tex Standard 100 Plus; SMaRT Sustainable Textile Standard also has a social component, though not as extensive as the other two. Then there is the Worldwide Responsible Apparel Production (WRAP) organization, which is “dedicated to the certification of lawful, humane and ethical manufacturing (of sewn products) throughout the world” Another one is the Fair Wear Foundation, whose members work towards improving the labor conditions in factories that produce garments throughout the world. In an earlier post (“How much does that lower price fabric really cost?”, 8.25.09) I talked about the group “War on Want”, a UK-based organization which has an on-going campaign for corporate accountability in the textile sector. There are also local organizations which promote workers rights, such as the National Garment Workers’ Federation (NGWF) in Bangladesh and Colectiva de Mujeres Hondurenas (CODEMUH) in Honduras. Also see our post on child labor in the cotton fields, “Happy May Day”, published on May 1, 2009.
But all of these organizations are focused on the sewn product arena; those workers who work in the mills have often been overlooked. From the August 8 post we make this plea: ” support those companies that are having their goods certified by third parties like Oeko Tex or GOTS. It costs money to have the certification process completed, in addition to the water treatment they must put in place, or any other changes that must be made to be compliant. GOTS has many requirements in the social justice area: no forced or bonded labor, no child labor, fair wages, the ability of workers to do collective bargaining, mandated rest periods, and safe and hygenic working conditions are just some of the requirements under GOTS. Some companies which HAD been certified are choosing to save money by not paying the fees to have the certifications extended when their payments become due” because the market is not demanding these certifications.
