FloorScore vs GREENGUARD Gold —
What EU Flooring Buyers Need to Know
FloorScore (SCS Global Services, certificate SCS-FS-05154) and GREENGUARD Gold (UL, certificate 135464-420) are both indoor air quality certifications for flooring — but they are not interchangeable. FloorScore tests against California Section 01350, referenced by LEED v4 and BREEAM. GREENGUARD Gold applies stricter limits designed for schools and healthcare — and is increasingly specified by UK NHS and North American institutional procurement. For EU commercial tenders, neither is legally mandatory — CE EN 14041 and national VOC schemes (AgBB for Germany, COV A+ for France) take precedence. However, holding both certifications simultaneously covers LEED v4, BREEAM, WELL v2, NHS procurement, and all North American green building programmes in a single product. Ecoflors SPC and LVT holds both.
Why This Confusion Exists — and Why It Matters
When a procurement manager receives a product data sheet showing both a FloorScore certificate and a GREENGUARD Gold certificate, the natural question is: are these the same thing? Do I need both? Which one does my project actually require? The confusion is understandable — both certifications appear on the same product, both reference indoor air quality, and both use broadly similar language around VOC emissions.
The confusion matters because specifying the wrong certificate for a tender submission can create a compliance failure — even if the product itself is perfectly safe. Specifically, a LEED v4 project that requires FloorScore cannot substitute GREENGUARD Gold, and an NHS procurement that names GREENGUARD Gold as a preferred standard cannot simply accept a FloorScore certificate in its place. Consequently, understanding the differences is not an academic exercise — it has direct procurement implications.
“Both certifications confirm low VOC emissions. The difference is which specific compounds are tested, at what limits, and for which building types each certification was designed.”
The Two Certifications: Identity, Issuer, and Standard
The Technical Difference: What Each Certification Actually Tests
The core difference between FloorScore and GREENGUARD Gold is the strictness of the VOC emission limits and the number of chemical compounds evaluated. Both certifications measure emissions from flooring products in a controlled chamber environment — but GREENGUARD Gold applies limits derived from the California Collaborative for High Performance Schools (CHPS) standard, which was specifically designed to protect children and immunocompromised patients in schools and healthcare facilities. These populations are more sensitive to chemical exposure than healthy adults, consequently the limits are set significantly lower.
VOC emission limits compared
| Compound | FloorScore limit (μg/m³) | GREENGUARD Gold limit (μg/m³) | Ecoflors test result |
|---|---|---|---|
| TVOC (Total VOC) | 500 μg/m³ | 220 μg/m³ | ＜2 μg/m³ · Pass both |
| Formaldehyde | 16.5 μg/m³ | 9 μg/m³ | ＜3 μg/m³ · Pass both |
| Acetaldehyde | 200 μg/m³ | 140 μg/m³ | ＜3 μg/m³ · Pass both |
| Toluene | 300 μg/m³ | 150 μg/m³ | ＜2 μg/m³ · Pass both |
| Benzene | 3 μg/m³ | 1 μg/m³ | ＜0.5 μg/m³ · Pass both |
| Styrene | 250 μg/m³ | 30 μg/m³ | ＜2 μg/m³ · Pass both |
| Number of compounds tested | 35+ | 360+ | Full panel — all pass |
The table makes the key point clear: GREENGUARD Gold’s limits are typically 2–8 times stricter than FloorScore across the same compounds. Furthermore, GREENGUARD Gold evaluates a significantly larger panel of chemical compounds — 360+ versus FloorScore’s 35+. A product that passes GREENGUARD Gold automatically satisfies FloorScore’s requirements. The reverse is not necessarily true.
Ecoflors SPC and LVT flooring produces VOC emissions so far below the limits of both schemes that holding both certifications simultaneously involves no additional product reformulation — only additional testing cost. Ecoflors TVOC result: ＜2 μg/m³ against a FloorScore limit of 500 μg/m³ and a GREENGUARD Gold limit of 220 μg/m³. The product’s actual emissions are 99.6% below the less strict standard. Holding both certificates means distributors can satisfy any tender specification from either standard without requesting a different product.
Market Acceptance: Which Certificate Is Required Where
This is the most common mistake EU importers make. For German public buildings and schools, the AgBB evaluation scheme is mandatory — FloorScore and GREENGUARD Gold are not accepted substitutes. For France, COV Classe A+ (Décret n°2011-321) is legally required for all flooring sold in France — neither FloorScore nor GREENGUARD Gold satisfies this requirement independently. Ecoflors carries the Eurofins IAC Gold certificate which covers AgBB, DIBt, COV A+ France, Belgian VOC regulation, and EU Taxonomy simultaneously — providing a single document that satisfies all EU national VOC schemes alongside both FloorScore and GREENGUARD Gold.
The Eurofins IAC Gold Connection: Why It Matters for EU Buyers
For EU-market distributors and contractors, there is a third certification that often creates additional confusion: the Eurofins Indoor Air Comfort (IAC) Gold label. This is not a competing scheme — it is an accreditation awarded by Eurofins laboratories to products that simultaneously satisfy multiple national and international VOC standards in a single test series.
Specifically, the Eurofins IAC Gold label covers: AgBB (Germany), DIBt (Germany), Belgian VOC Regulation, French COV Classe A+, EU Taxonomy Article 9/10, REACH 2023, Blue Angel DE-UZ 120, BREEAM, LEED v4.1, and WELL v2 — all from a single test report. Ecoflors holds Eurofins IAC Gold, which means that a single certificate satisfies all EU national VOC requirements and all major international green building programmes simultaneously. This is what allows Ecoflors to supply the Netherlands, Germany, the UK, France, and Canada without issuing separate VOC reports for each market.
Ecoflors Certificate Numbers: What to Quote on Your Tender
Which Certification Should You Specify? The Decision Guide
FloorScore is the standard directly referenced by LEED v4 EQ Credit 2 (Low-Emitting Materials) and BREEAM Mat 03. For most North American commercial projects and EU green building certifications, FloorScore is the correct certification to quote. Certificate: SCS-FS-05154.
SCS-FS-05154GREENGUARD Gold is required or strongly preferred for sensitive environments — schools, hospitals, paediatric care, and any project targeting WELL v2 or Living Building Challenge certification. UK NHS procurement increasingly specifies GREENGUARD Gold by name. Certificates: 135464-420 (SPC) · 135462-420 (Dryback) · 135463-420 (Loose Lay).
135464-420 / 135462-420 / 135463-420For Germany (AgBB, DIBt) and France (COV Classe A+), request the Eurofins IAC Gold test report. This covers all EU national VOC schemes in one document. Neither FloorScore nor GREENGUARD Gold satisfies AgBB or COV A+ independently — the Eurofins report is the correct documentation for EU tender submissions.
Eurofins IAC Gold — EU national VOCFor distributors supplying multiple markets — EU and North America simultaneously — quoting both FloorScore and GREENGUARD Gold eliminates the need to verify which specific certification a particular project requires. Furthermore, for OEM programme members, Ecoflors reissues all certificates under the buyer’s company name, making the documentation directly submittable on any tender without identifying the underlying manufacturer.
FloorScore + GREENGUARD Gold + Eurofins IAC GoldThe Practical Takeaway for Importers and Contractors
In day-to-day B2B procurement, the difference between FloorScore and GREENGUARD Gold rarely creates a compliance problem — because most flooring products that hold one certification also hold the other, and most procurement teams accept either. The difference becomes critical in three specific scenarios: WELL v2 certification, NHS procurement, and any project that explicitly names one standard in the specification document.
Moreover, for EU-market importers, both certifications are secondary to the national VOC requirements. A Dutch importer who quotes FloorScore for a Woningcorporaties tender should also be able to produce the CE DoP and confirm EN 16516 VOC class. A German contractor specifying a school fit-out needs the AgBB report — not FloorScore. Knowing when each certificate applies — and having all of them — is the difference between a supplier that can close any tender and one that creates compliance uncertainty for its distribution partners.
Consequently, the simplest procurement rule for flooring buyers sourcing from China is: ask your supplier for FloorScore certificate number, GREENGUARD Gold certificate number by product line, and Eurofins IAC Gold test report. If your supplier can provide all three, the product satisfies every IAQ specification you are likely to encounter in the EU, UK, US, and Canada simultaneously.
