Mettons au défi l’industrie des chaussures d’extérieur d’éliminer les PFC d’ici 2025
DÉSINTOXIQUER LA PLANÈTE

Mais que sont les PFC?
Les perfluorocarbures (PFC) sont un groupe de produits chimiques fabriqués par l’homme qui comprend environ 5 000 composés fluorés connus sous le nom de PFA, ou de substances per- et polyfluoroalkyl. On les appelle les « polluants organiques persistants » (« forever chemicals ») en raison de leur longévité. Ces produits chimiques toxiques ne se décomposent jamais, ils restent dans l’environnement et pénètrent dans la chaîne alimentaire. Aujourd’hui, on les retrouve partout, depuis les emballages de produits de restauration rapide jusqu’à l’eau potable, en passant par les traitements déperlants durables (TDR) dans les vêtements et les chaussures d’extérieur.
Le problème avec les PFC
Les PFC sont efficaces pour résister à une grande diversité d’éléments, que ce soit la chaleur, l’huile, les taches, la graisse et l’eau, et c’est pourquoi ils sont utilisés pour tout traiter, des vêtements aux meubles en passant par les emballages alimentaires et les surfaces de cuisson antiadhésives. Mais ils n’en restent pas là. Des traces de ces produits chimiques toxiques pénètrent dans l’environnement et ne disparaissent jamais. Il existe par ailleurs des preuves que l’exposition aux PFC peut entraîner des effets néfastes sur la santé chez l’humain.
Selon les Centres pour le contrôle et la prévention des maladies (Centers for Disease Control and Prevention, CDC), « les produits chimiques de ce groupe sont préoccupants, parce qu’ils ne se désagrègent pas dans l’environnement, et s’accumulent dans la faune. Des PFC ont été retrouvés dans les rivières et les lacs, et dans de nombreux animaux sur terre et dans l’eau. »
Ils ont également été retrouvés dans notre sang. Dans le Quatrième rapport national sur l’exposition humaine aux produits chimiques environnementaux, les scientifiques des CDC ont détecté 12 PFC dans le sérum sanguin de 2 094 participants âgés de 12 ans et plus qui ont participé à l’Enquête nationale sur la santé et la nutrition (NHANES) entre 2003 et 2004.
Leurs conséquences sur la santé humaine sont moins connues. Mais les CDC ajoutent que les PFC peuvent altérer la croissance et le développement, la reproduction et endommager le foie.
FAQ et où en apprendre davantage
Les perfluorocarbures et les substances polyfluoroalkyl sont de très longs mots difficiles à épeler et à prononcer. Voici un peu d’aide et des réponses aux questions que nous recevons le plus souvent.
What are PFCs?
PFC stands for “perfluorinated chemicals” and is a broad term that some scientists use to refer to a group of chemicals that includes PFAS, or “per- and polyfluoroalkyl substances.” PFAS chemicals are man-made, bioaccumulative, and very unhealthy for our environment and human health. They are found everywhere, and degrade very slowly, if at all, under natural conditions. Because of all this, they are known as “forever chemicals.” To make things even more confusing, PFC can also refer to a distinct subclass of perfluorinated chemicals, perfluorocarbons, which are distinct from PFASs in their chemical structure and health impacts.
To be clear, when we talk about PFCs, we are referring to PFAS chemicals.
Why is this important?
PFAS chemicals have been found to cause liver toxicity, disruption of metabolism, the immune and endocrine systems, adverse neurobehavioral effects, and complications with pregnancy — including neonatal toxicity, reduced birth weight, seizures, and death. They have also been shown to cause significant hormonal disruptions, hypothyroidism, multiple organ tumors, testicular and kidney cancers, liver malfunction, high cholesterol, ulcerative colitis, obesity, decreased immune response to vaccines, and delayed puberty. The EPA reports that PFAS groundwater contamination is problematic in 33 states, with high population states like California, New Jersey, North Carolina, Florida, Pennsylvania, Ohio, and New York.
Are all KEEN products PFC Free?
We actively ban all PFAS chemical compounds from our supply chain. We say our products are 97% PFC Free — because of the massive amount of environmental contamination (it’s in the bottom of the ocean, the clouds, and in the blood of polar bears!), there’s no way that we can guarantee being 100% PFC Free. We test for contamination regularly, and we consider this an endless journey of constant vigilance.
How long have KEEN products been PFC Free?
We started identifying and intentionally removing PFASs from our supply chain starting in 2014. We removed 65% within the first year. It took us three more years to eliminate the rest. By 2018, we could confidently say we were PFC Free.
What about older products?
KEEN products produced before 2018 may have PFAS-based water repellency.
What about the KEEN products that Amazon/other retailers have? Are those PFC Free?
No matter their distribution, all KEEN products go through the same rigorous testing protocols to ensure our PFAS standards.
But it doesn’t say “PFC Free” on the box or the shoe. How do I know if my shoes are PFC Free?
We don’t label this on our shoes or packaging. If they are KEEN shoes built after 2018, they are PFAS-free. You can find the date of manufacture of your KEEN shoes on the inside shoe tag, sometimes found on the tongue or the medial ankle. Usually the date is at the bottom right corner of the tag, appearing as MMDDYY.
There is no universal standard or label for this, but our friends at the Green Sciences Policy Institute have a list of recommended brands and products that actively eliminate PFAS and other classes of toxic chemistries from their products/supply chains.
Are all kids’ shoes PFC Free?
Yes, all KEEN Kids shoes are PFAS Free and meet the same standards as all of our other products.
What safe alternative is KEEN using to replace PFCs in its water repellency treatment?
We source “green alternatives” from two major chemical suppliers, Rudolf and 3M, which both provide safe and effective DWR (durable water repellency) treatments that do not include fluorinated chemistries.
Does KEEN have a Restricted Substances Policy?
Yes, we have a Restricted Substances Policy. Our Policy is based on the industry-standard Apparel and Footwear International RSL Management Group (AFIRM) restricted substances list, and designed to ensure that our products meet all required global standards. Our Policy also includes four additional compounds restricted by KEEN as part of our efforts to proactively use more sustainable chemistry.
How do you measure the environmental impact of your supply chain?
Each year, KEEN and its significant suppliers complete the Higg Index. Managed by the Sustainable Apparel Coalition, the Higg Index is a tool used by companies all over the world – including KEEN – to elevate sustainability in manufacturing by measuring impacts and monitoring progress in reducing environmental impacts. The Higg requires that we examine all aspects of our company’s operations from materials selection, to shipping, to end of use, and solicit input from employees across the company, including product engineers, operations managers, and product developers. The Higg is a key way we increase transparency into our supply chain, gauge performance, and drive improvements year over year.
Does KEEN work together with other groups on sustainability?
Yes, we work with a variety of working groups, brands and retailers from around the world on sustainability. Examples include:
- European Outdoor Group: The EOG Sustainability Working Group works in support of the outdoor industry in the areas of corporate social responsibility and product sustainability.
- Leather Working Group: This multi-stakeholder group assesses the environmental compliance and performance capabilities of leather tanners, and promotes sustainable and appropriate environmental business practices within the leather industry.
- Outdoor Industry Association: The OIA Sustainability Working Group is a collaborative effort among more than 300 outdoor brands, retailers, suppliers and other stakeholder organizations working to identify and implement better business practices throughout our supply chains.
- Sustainable Apparel Coalition: The SAC is transforming the apparel, footwear and home textiles industry through system-wide collaboration in pioneering assessment tools and supply chain transparency with the Higg Index suite of measurement tools.
