What Is the Difference Between PVC-Free and Low-VOC Commercial Flooring?

PVC-free and low-VOC are two of the most common environmental claims on commercial flooring spec sheets, and they are not interchangeable. PVC-free describes what a product is made without: polyvinyl chloride and the plasticizers used to soften it. Low-VOC describes what a product emits into indoor air after installation. One is a statement about ingredients, the other about emissions, and a floor can be either one without being the other.

Green building frameworks treat these as separate credits, and manufacturers' marketing sometimes blurs them together. The sections below explain what each claim covers, which flooring categories qualify, how each is verified, and how to read them side by side on a spec sheet.

What Is PVC-Free Commercial Flooring?

PVC-free flooring is manufactured without polyvinyl chloride, the plastic behind most resilient flooring sold today. It is a claim about composition only. It does not describe durability, slip resistance, recycled content, or emissions, and it does not mean a product is free of every other chemical of concern, which is why the most credible PVC-free products pair the claim with a Declare label or a Health Product Declaration (HPD) that shows what is in the product. Declare labels carry one of three statuses. Red List Free and Red List Approved both satisfy the Living Building Challenge Red List imperative (Approved products contain a Red List ingredient covered by a published exception); a label marked only Declared does not.

Why Is PVC Singled Out?

PVC draws scrutiny because of its full life cycle rather than how it behaves on the floor. Its building block, vinyl chloride monomer, is a recognized human carcinogen. Making and burning PVC involves chlorine chemistry that can produce persistent byproducts, and rigid PVC has to be softened with plasticizers to become a flexible floor. Historically those plasticizers were ortho-phthalates; the major North American resilient manufacturers and big-box retailers committed to removing them from domestically made vinyl flooring, though they still appear in some imported products. Some formulations have also relied on heavy-metal stabilizers. For these reasons the International Living Future Institute places PVC on its Red List alongside ortho-phthalates, halogenated flame retardants, and other materials it considers the worst-in-class for human and ecological health.

Which Flooring Categories Are PVC-Free by Nature?

Most of the commercial flooring market is already PVC-free; the exception is the resilient category, where PVC dominates. The table below sorts the common types.

The PVC-free resilient category is the fastest-evolving segment, as manufacturers develop polymer alternatives to LVT, sometimes marketed as non-PVC or vinyl-free flooring, that meet both material health and emissions requirements. These products install and perform much like conventional LVT, and since 2018 the category has moved from a handful of premium products toward price parity with domestic LVT. It is also where labeling matters most, because a single collection can contain both LVT and PVC-free styles that look identical.

If PVC-free is about what goes into a floor, low-VOC is about what comes out of it.

What Is Low-VOC Commercial Flooring?

Low-VOC flooring emits volatile organic compounds at levels below a recognized health-based threshold once installed. VOCs are carbon-based chemicals that evaporate at room temperature; in flooring they come from residual solvents, plasticizers, binders, and finishes, and they are the main reason a new floor has a smell. Low-VOC is a claim about emissions over time, verified by chamber testing, and it says nothing about what the product is made of.

How Are VOC Emissions Tested?

In North America, the reference method is the California Department of Public Health's Standard Method, usually called CDPH Section 01350. A sample is conditioned for ten days, placed in a sealed chamber, and measured at day 14. Individual VOCs must fall at or below half of California's chronic reference exposure level, with formaldehyde capped separately. Results are modeled for a standard school classroom and private office, and the certificate reports total VOCs in one of three ranges (0.5 mg/m³ or less, 0.5 to 5 mg/m³, or above 5 mg/m³). Most certified commercial flooring reports at or below 0.5 mg/m³, so the range on a certificate is a quick way to compare products.

Which Certifications Verify Low-VOC Claims? 

All four are third-party programs, and all four are accepted by LEED's low-emitting materials credit when the testing follows CDPH.

What Low-VOC Does Not Tell You

First, the floor is often not the biggest VOC source in a flooring assembly. Adhesives, primers, and finishes can emit more than the product they attach, which is why LEED sets separate requirements for adhesives and sealants. A low-VOC floor installed with a high-VOC adhesive does not deliver a low-VOC room.

Second, "low-VOC" and "zero-VOC" are different claims. Zero-VOC usually refers to VOC content measured in the wet product (paints and adhesives), while low-VOC flooring claims rest on emissions measured in a chamber. A product can be formulated with very low VOC content and still emit measurable VOCs, and vice versa. When a spec requires low-emitting flooring, the emissions certificate is the document that satisfies it. This is why an HPD for a floor will often state that VOC content “is not applicable for this product category”: flooring is judged on emissions, and the content figure belongs to wet-applied products.

PVC-Free vs. Low-VOC: The Key Differences

The simplest framing: PVC-free is about chemistry in; low-VOC is about chemistry out.

A vinyl floor can earn FloorScore if its emissions fall within the CDPH limits, and most commercial LVT does. A PVC-free floor is not automatically low-emitting: rubber, polyurethane, and bio-based resilient products all have to pass the same chamber test, and some early PVC-free products struggled with odor. In practice the two claims overlap often, because manufacturers pursuing one tend to pursue both, but the overlap is a market pattern, not a rule, and each claim has to be documented on its own.

Common Misconceptions

"PVC-free means the product is automatically low-VOC." PVC-free confirms the absence of one material. It does not certify anything about emissions, and a product can be formulated without PVC yet still emit VOCs above the CDPH thresholds. Look for both a material disclosure (Declare or HPD) and an emissions certificate.

"If a floor is low-VOC, it must also be PVC-free." Emissions certifications measure what comes off the product, not what is in it. The majority of FloorScore-certified products on the market are vinyl.

"If one style in a collection is PVC-free, they all are." PVC-free status applies style by style, and manufacturers increasingly offer LVT and PVC-free resilient versions of the same visual in the same collection. Read the construction line on the spec sheet, not the collection name, and confirm the exact style number before specifying.

"Low-VOC flooring guarantees a low-VOC room." The adhesive, primer, moisture mitigation, and finish all emit too, and adhesives are often the larger source. Specify the full assembly to the same standard.

"PVC-free is the greener choice, full stop." PVC-free addresses a specific set of chemical concerns. It does not by itself say anything about embodied carbon, recycled content, durability, or end-of-life recovery, and some PVC-free materials carry their own life-cycle trade-offs. Treat it as one filter among several, weighted by what the project's framework requires.

How Do the Two Claims Map to Green Building Frameworks?

The frameworks treat the two claims as separate credits, and no major program requires both. The table shows where each claim counts.

Two points follow from the table. Under LEED, a project can earn every available flooring point with a vinyl floor as long as it is low-emitting and documented with an HPD or EPD, so PVC-free is a choice rather than a requirement. Under the Living Building Challenge, the Red List makes PVC-free a practical prerequisite and the Healthy Interior Performance imperative demands low emissions as well, so LBC projects need products that satisfy both.

Practical Guidance for Specifiers

For most commercial projects, specify both: PVC-free is the deciding filter for Living Building Challenge work and for owners with a stated PVC policy (common in healthcare and education), while a CDPH-based emissions certificate is the deciding filter for LEED and WELL low-emitting credits. Treat the two as complementary filters rather than competing priorities.
 

1. Start with the project's framework. Read the credit language before writing the spec. LEED and WELL reward emissions; LBC and many healthcare owner standards exclude PVC outright. 
    
2. Ask for two documents. A Declare label or HPD answers what is in the product. A FloorScore, Indoor Advantage Gold, Green Label Plus, or GREENGUARD Gold certificate answers what comes off it. A product with only one of the two has only answered half the question.
    
3. Verify at the style level. Pull the spec sheet for the exact style number and read the construction line. Collection names, brochure headlines, and product photos do not establish PVC-free status.
    
4.  Specify the whole assembly. Carry the emissions requirement through to adhesives, primers, and finishes, and require SCAQMD Rule 1168 compliance for adhesives on LEED projects.
    
5. Review third-party marks and check the registration. Every legitimate certificate carries a registration number that can be looked up on the certifier's site. Self-reported "low-VOC" or "eco-friendly" language without a registered certificate should not satisfy a spec.
    
6. Weigh PVC-free against the project's other goals. If embodied carbon, recycled content, or long-term durability matter more to the owner than Red List compliance, a well-documented vinyl product may be the right answer.

What Do PVC-Free and Low-VOC Claims Look Like Together?

A worked example from Mohawk Group's own portfolio, the one we can document fully, shows how the two claims sit side by side. Mohawk Group's soft surface line is PVC-free across the board: every carpet tile and broadloom style is made without PVC, and the carpet tile is manufactured at a Living Product Challenge-certified site in Glasgow, Virginia. On the hard surface side, PVC-free is applied style by style rather than to whole categories. The current PVC-free resilient styles are listed on the PVC Free page and can be isolated with the hard surface filter.

The same collection that holds Bolder 3.0 and Secoya 3.0 also holds Bolder and Secoya LVT styles at 2.5 mm and 5.0 mm. Those LVT styles are vinyl products , FloorScore certified, appropriate for projects where emissions performance is the priority and PVC exclusion is not a requirement.

FAQ

Is LVT PVC-free? No. Luxury vinyl tile is a vinyl product, and vinyl is PVC. Products marketed as PVC-free alternatives to LVT are made from polyolefin, polyurethane, polyester, or rubber and are labeled as PVC-free resilient rather than LVT.

Does FloorScore mean a product is PVC-free? No. FloorScore certifies emissions against the CDPH Standard Method. It says nothing about ingredients, and most FloorScore-certified flooring is vinyl. To confirm PVC-free status, look for a Declare label or an HPD.

Is PVC-free flooring required for LEED? No. LEED's flooring credits are based on emissions testing and ingredient transparency, not on excluding any particular material. PVC-free products can help earn material ingredient points but are not a standalone requirement.

Is PVC-free flooring required for the Living Building Challenge? Effectively, yes. PVC is on the ILFI Red List, so products containing it are not permitted on LBC projects without a documented exception.

Which flooring types are naturally PVC-free? Carpet (check the backing), rubber, linoleum, cork, wood, ceramic and porcelain tile, terrazzo, polished concrete, and the newer PVC-free resilient category. LVT, sheet vinyl, and VCT contain PVC.

What is the difference between low-VOC and zero-VOC? Zero-VOC usually describes the VOC content of a wet product such as paint or adhesive. Low-VOC flooring describes measured emissions from the installed product in a test chamber. Flooring specs should call for the emissions certificate.
