Synthetic carpets are complex in their composition and chemistry. The many components used to make a durable carpet present a variety of hazards in their backing, pile, and surface treatments. There is a litany of additives used to resist mildew, stains, and fire which makes it essential to examine each component of a carpet product before accepting it as "healthier".

Below are a few examples of carpets that meet our rigorous evaluation. For further help on your own search for healthier carpet products, scroll down to "Spec Guidance.

About Our Collections

The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.

Keep an eye out for the following symbols:
A Healthier Affordable Building Product

Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.

Available at the Donghia healthier Materials Library

The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.

Low Embodied Carbon

“Embodied Carbon” is the total amount of carbon emitted during the process of making a material. *HML refers to a manufacturer's EPD to determine whether a product's A1-A3 carbon emissions falls within HML's threshold for Low Embodied Carbon.

New Product

This product has been added to the collection within the past six months.

Product in Development

Products with this designation identify they are currently scaling or only available in markets outside of the building industry. they could be experimental or in use in capsule collections.

Available in the EU

Products with this designation are currently available only in the European Union and identified as being an exemplary healthy option in the respective product group.

Ingredient Disclosures

There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.

Key Disclosures include:
Health Product Declaration (HPD)

A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).

Declare Label

Declare is a transparency platform and product database that answers three questions:
1. Where does a product come from?
2. What is it made of?
3. Where does it go at the end of its life?

Environmental Product Declaration (EPD)

A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.

Safety Data Sheet (SDS)

A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.

USDA Certified Biobased Product Label

Managed by the U.S. Department of Agriculture (USDA), the goal of the BioPreferred Program is to increase the purchase and use of biobased products.

EcoWorx Carpet Tile

Available At the Donghia Materials Library
Low-Embodied Carbon Material

Patcraft's EcoWorx carpet tile is a non-PVC backed carpet tile. Per manufacturer, all EcoWorx carpet tile with nylon are Cradle to Cradle Certified® Silver. Reverse is an exception, as the manufacturer set out to obtain a Gold level certification. Using a carefully curated selection of yarn colors for the collection, the styles of Reverse were able to pass the Cradle to Cradle Product Standard's Restricted Substance List (RSL) to achieve Gold in the Material Health pillar. This HPD relates to several EcoWorx collections, including Reverse and Artefact. All pigments fall below the 1000 ppm reporting threshold for the HPD and most pigments fall below the 100 ppm threshold for Declare, hence no need for separate (HPD/Declare) certifications for the C2C Gold collection. Shaw guarantees free reclamation and recycling at the end of use.

Per Patcraft's product-specific EPD, this product meets HML's criteria for low embodied carbon.

The products in this collection have all been evaluated holistically for their contents and performance. To be considered, a product must disclose at least 75% of its ingredients by weight. It should avoid the biggest health concerns (such as those indicated in the HML Spec guidance for this product category) or be third-party certified.

Aluminium Hydroxide or Aluminum Trihydrate (ATH), CAS# 21645-51-2 is used as a flame retardant and a filler in many building products. As it is a Greenscreen BM-2, the Lab continues to watch the scientific evaluation of this substance.


Spec Guidance

Prefer carpet tiles that attach with carpet tacks as opposed to adhesives. Carpet tacks allow for easy replacement of damaged tiles, and tend to be free of toxic additives that are common in traditional adhesives.

Avoid carpets with stain-resistant treatments such as PFAS (perfluoroalkyl substances). These chemicals (such as PFOA and PFOS) are persistent in the environment and linked to a wide range of health issues. Several companies have eliminated or are working on avoiding PFAs in their products.

Avoid carpets with vinyl and polyurethane backings — these often contain harmful plasticizers and/or flame retardants.

Avoid carpets containing fly ash, which may contain heavy metals such as mercury.

Look to established standards. The city of San Francisco currently has some of the strictest restrictions around carpets. Among other requirements, carpets must be Cradle to Cradle Certified Silver or higher, have HPDs or Declare labels, and be free of flame retardants, PFAs, fly ash, PVC, and polyurethane. (San Francisco Department of the Environment)
