Key Takeaways
French A+, GreenGuard and EPD are not rival certifications competing for the same claim — each one measures a genuinely different thing
French A+ and GreenGuard both test indoor air quality and VOC emissions, just under different regional systems (French regulation vs. US-based certification)
EPD measures something entirely different: a product's full lifecycle environmental impact, including carbon footprint — not indoor air safety
Several other labels (FloorScore, IAC Gold, CE, CARB, REACH/SVHC, CAM, AgBB) show up on flooring spec sheets too, and each answers its own narrow question — see the quick-reference table below
The most trustworthy flooring isn't the one with the single "best" certification, but the one that holds verified documentation across both air-quality and lifecycle categories
Introduction (French A+ vs GreenGuard vs EPD)
If you've compared flooring specs recently, you've probably noticed a wall of certification logos on every product page — French A+, GreenGuard, EPD, FloorScore, IAC Gold, CARB, REACH — often with no clear explanation of what any of them actually verify. It's tempting to assume they're all measuring roughly the same thing, and that more logos simply means "safer" or "greener."
That assumption is where most confusion starts. These certifications aren't different brands competing to prove the same claim — they're answering fundamentally different questions. Understanding what each one actually measures is the difference between reading a spec sheet and just seeing a wall of badges.
This guide breaks down what French A+, GreenGuard and EPD each actually verify, why they're not substitutes for one another, and what the rest of the alphabet soup on a flooring label actually means.

What Each Certification Actually Measures
French A+: Indoor Air Emissions, French Regulatory Standard
French A+ is a mandatory emissions classification under French regulation (Décret n°2011-321), in place since 2012 for construction, decoration and furnishing products sold in France. It rates volatile organic compound (VOC) emissions on a scale from A+ (very low emissions) to C (higher emissions), based on testing methodology derived from ISO 16000.
In practice, this label answers one specific question: how much does this product off-gas into the air of the room it's installed in? It says nothing about the product's carbon footprint, water use, or what happens to it at the end of its life — only about indoor air emissions.
GreenGuard: Indoor Air Emissions, US-Based Certification System
GreenGuard, administered by UL Solutions, is functionally answering the same underlying question as French A+ — indoor air quality and VOC emissions — but through a separate, US-based certification program rather than a European regulatory requirement. Products are tested in controlled chambers for specific chemicals and total VOC levels, then benchmarked against health-based emission limits. A stricter tier, GreenGuard Gold, sets lower limits still and is commonly referenced for schools, healthcare settings and homes with children.
Because French A+ and GreenGuard both sit in the "indoor air emissions" category, they're often seen side by side on the same product — not because one supersedes the other, but because different markets and specification systems reference different labels for the same underlying concern.
EPD: Full Lifecycle Environmental Impact — Not Air Quality
An Environmental Product Declaration (EPD) is a different category of document entirely. Rather than testing what a product emits into a room, an EPD is a verified report of a product's environmental impact across its full lifecycle — from raw material extraction through manufacturing, and depending on scope, through disposal or recycling. It's built on Life Cycle Assessment (LCA) methodology, typically aligned with EN 15804 and verified to ISO 14025.
An EPD covers metrics like carbon footprint (global warming potential), water use and other environmental impact categories — none of which overlap with what French A+ or GreenGuard measure. A product can have an excellent EPD and a mediocre emissions profile, or vice versa, because the two documents are answering different questions.
Side-by-Side: What Each Certification Actually Tells You
Certification | What It Measures | Governing Standard | Answers the Question |
French A+ | Indoor VOC emissions | Décret n°2011-321, ISO 16000 basis | "Will this affect the air quality in my home?" |
GreenGuard | Indoor VOC/chemical emissions | UL certification program | "Will this affect the air quality in my home?" (US-based system) |
EPD | Full lifecycle environmental impact (carbon, water, etc.) | EN 15804 / ISO 14025 | "What is this product's overall environmental footprint?" |
Why These Aren't Competing Certifications
Treating "French A+ vs GreenGuard vs EPD" as a competition to find the single most trustworthy label misses how these documents actually work together. French A+ and GreenGuard are two regional answers to the same air-quality question — a well-documented product often carries both, simply because different markets specify different labels. EPD sits in a separate category altogether, answering a sustainability question that emissions certifications were never designed to address.
A genuinely well-documented floor doesn't win by picking the "best" certification and skipping the rest — it holds verified documentation across both categories, because a family checking for safe indoor air and a specifier checking for lifecycle carbon data are asking two different questions, and neither should have to take a marketing claim at face value.
Other Common Flooring Certifications at a Glance
French A+, GreenGuard and EPD are the three that come up most often, but they're rarely the only labels on a spec sheet. Here's what the rest of the alphabet soup actually means:
Certification | What It Measures | Region / Body |
FloorScore | VOC emissions specific to flooring products and adhesives | US — administered by SCS Global Services, referenced in LEED and other green building programs |
IAC Gold (Indoor Air Comfort Gold) | A composite European emissions certification combining several national VOC standards (including AgBB and French A+ criteria) into one premium threshold | Europe — Eurofins-administered |
CE Marking | Confirms a product meets baseline EU health, safety and environmental requirements for sale in the European market | European Union — regulatory, not a voluntary eco-label |
AgBB | A German scheme for evaluating VOC emissions from building products, often used as a benchmark within other certifications | Germany |
CAM (Criteri Ambientali Minimi) | Italy's minimum environmental criteria for public procurement of building materials, including emissions thresholds | Italy |
REACH / SVHC | Confirms a product does not contain Substances of Very High Concern above EU-regulated limits — a chemical safety check, not an air-quality or lifecycle metric | European Union |
CARB Phase 2 | US regulatory limit on formaldehyde emissions from composite wood products | United States (California, widely referenced nationally) |
A quick way to sort them: French A+, GreenGuard, FloorScore, IAC Gold, AgBB and CARB Phase 2 all sit in the "what does this emit into my room" category, just under different regional systems. CE marking and REACH/SVHC are baseline regulatory and chemical-safety checks rather than performance ratings. EPD (and CAM's broader sustainability criteria) sit apart from all of them, in the lifecycle-impact category.
Frequently Asked Questions
Q: Is EPD better than GreenGuard or French A+?
A: Neither is "better" — they measure different things. GreenGuard and French A+ assess indoor air emissions; an EPD documents a product's full lifecycle environmental impact, including carbon footprint. A well-documented floor typically has both types of certification, not one instead of the other.
Q: Do I need to check French A+ if a product already has GreenGuard certification?
A: It depends on your market and what you're comparing against. Both certifications test a similar underlying concern (VOC emissions) through different systems — French A+ is specifically the regulatory standard for products sold in France, while GreenGuard is a US-based certification program. Checking both gives a fuller picture if you're comparing products across markets.
Q: What does an A+ rating actually mean in practice?
A: It means the product's tested VOC emissions fall into the lowest, safest tier on the French classification scale (A+ to C), based on ISO 16000 testing methodology. It's specifically about what the product releases into indoor air — not about how it was manufactured or its broader environmental footprint.
Q: Does having an EPD mean a product is automatically eco-friendly?
A: Not automatically — an EPD is a transparent, verified report of environmental impact, not a pass/fail eco-label. What matters is what the actual data in the EPD shows (carbon footprint per square metre, recycled content, etc.), which is why it's worth looking at the underlying figures rather than just the presence of the certification.
Q: What's the difference between FloorScore and GreenGuard?
A: Both test VOC emissions, but FloorScore is specific to flooring products and adhesives and is widely referenced in green building programs like LEED, while GreenGuard covers a broader range of product categories under UL's certification program. A flooring product can reasonably carry both.
Q: Are CE marking and REACH/SVHC the same as an emissions certification?
A: No. CE marking confirms a product meets baseline EU safety and regulatory requirements to be sold in Europe, and REACH/SVHC confirms it doesn't contain restricted substances above legal limits. Neither measures how much a product off-gasses the way French A+, GreenGuard or FloorScore do — they're regulatory and chemical-safety checks, not performance ratings.
What This Looks Like in Practice
Certification documentation varies a lot from one flooring product to the next, even within the same brand — it's tied to the specific product line and manufacturing batch, not a blanket brand-wide guarantee.
As one example, Braag's engineered vinyl collections (including Skyline, Palette, Spirit and Summit) are tested with TVOC emissions after 28 days coming in under 5 μg/m³ — well inside the threshold for French A+ classification — and are documented with an EPD covering cradle-to-gate and end-of-life carbon figures per collection, alongside FloorScore, GreenGuard, IAC Gold, CE marking, CAM, AgBB and REACH/SVHC documentation.
The practical takeaway isn't which single logo to look for — it's whether a manufacturer makes both categories of documentation available: the air-emissions data and the lifecycle data.
Final Verdict
"Which certification should you trust" is, in a sense, the wrong question — French A+, GreenGuard and EPD aren't competing to prove the same thing, so trusting one over the others doesn't actually answer both concerns a homeowner has. French A+ and GreenGuard tell you about the air you'll be breathing in the room.
EPD tells you about the footprint the product left before it got there. The other labels on the spec sheet — FloorScore, IAC Gold, CE, REACH, CARB — each narrow that picture further. A floor worth trusting documents across all of these categories, rather than leading with a single badge and hoping you don't ask about the rest.
