When you're buying flooring in the GTA, the word "certified" comes up a lot — but what does it actually mean? Three certifications appear on flooring labels most often: FloorScore, GREENGUARD, and CARB2. They sound similar, but they test different things, apply to different products, and matter in different situations. Here's what each one covers and why they show up on the flooring you buy at Top Floorings Depot.
What Is CARB2?
CARB2 stands for California Air Resources Board Phase 2 — a regulation that sets limits on formaldehyde emissions from composite wood products. If you see CARB2 on a flooring label, it means the MDF, particleboard, or plywood core in that product has been tested and meets one of the world's strictest formaldehyde standards. This standard was adopted in the US in 2011 and is now referenced in building codes across North America, including Ontario.
The reason it shows up on flooring: many laminate floors and some engineered hardwood products use an MDF or HDF core. Without CARB2 compliance, those cores can off-gas formaldehyde over time — particularly when heated. CARB2 compliance is not optional for flooring sold in Canada when the product uses composite wood cores. Every German-made laminate at Top Floorings Depot — including our full laminate collection — comes from manufacturers that meet CARB2 requirements.
What Is FloorScore?
FloorScore is a certification from SCS Global Services that tests finished flooring products for volatile organic compound (VOC) emissions. Where CARB2 focuses on composite wood cores, FloorScore tests the complete finished floor — the surface layer, the core, the backing, and any adhesives used in the product. A FloorScore-certified product has been independently tested to confirm it meets CDPH (California Department of Public Health) emission standards for indoor air quality.
For GTA homeowners, FloorScore shows up most often in two situations: condo board requirements and health-conscious purchases. Many Toronto condo buildings require that flooring installed in common areas or rental units carry FloorScore or an equivalent certification. If you're renovating a condo in Scarborough, North York, or downtown Toronto, check with your property manager — FloorScore compliance may be on the checklist.
All Swiss Krono laminate products, which carry an AC6 rating and are made in Germany, are FloorScore certified. Riche Flooring SPC vinyl products are also FloorScore certified across all thickness tiers, from 6mm budget series through 10mm ultra-thick planks. This means you can install Riche SPC vinyl in a condo or basement apartment and know the product has been independently verified for indoor air quality.
What Is GREENGUARD?
GREENGUARD (and the stricter GREENGUARD Gold) is a certification program also run by UL Solutions that tests products for chemical emissions into indoor air. GREENGUARD Gold goes further than the standard GREENGUARD mark — it sets lower emission limits and accounts for the sensitivity of environments like schools and healthcare facilities. Both certifications are widely recognized in North American building standards, including LEED certification for green buildings.
The difference between FloorScore and GREENGUARD is subtle but real. FloorScore is specifically designed for flooring and focuses on emissions that affect indoor air quality in homes and offices. GREENGUARD is broader — it applies to hundreds of product categories beyond flooring, from paint to furniture to building materials. For a homeowner, if a product carries both FloorScore and GREENGUARD Gold, that product has been tested more rigorously than one with just one mark.
Top Floorings Depot carries several laminate and SPC vinyl products that meet GREENGUARD Gold standards, including the Swiss Krono 14mm AC6 line. When you're comparing two similar-looking products and one has GREENGUARD Gold and one doesn't, the certified product has passed third-party emissions testing that the other hasn't.
CARB2 vs FloorScore vs GREENGUARD: What's the Difference?
These three certifications don't compete — they cover different parts of the product:
| Certification | What It Tests | What It Applies To | Why It Matters in the GTA |
|---|---|---|---|
| CARB2 | Formaldehyde emissions from composite wood cores | Laminate flooring, some engineered hardwood (MDF/HDF core) | Required by Ontario building standards for products using composite wood |
| FloorScore | Total VOC emissions from finished flooring | Hard surface flooring — laminate, SPC vinyl, engineered hardwood, solid hardwood | Required by many Toronto condo boards for installed flooring |
| GREENGUARD Gold | Lowest VOC and chemical emissions for sensitive environments | All interior products including flooring, paint, furniture | Preferred in healthcare, schools, childcare — and for anyone with chemical sensitivity |
In practical terms: a laminate floor with CARB2 compliance has a safe core. Add FloorScore and you know the whole finished product has been tested for indoor air quality. Add GREENGUARD Gold on top of that and you have one of the most rigorous emissions certifications available for any interior building product.
Which Certification Do You Actually Need?
For most GTA homeowners, the answer is simple: CARB2 is the baseline minimum, FloorScore is what your condo board will ask for, and GREENGUARD Gold is the extra step worth paying slightly more for if anyone in the home has allergies, asthma, or chemical sensitivities.
If you're buying for a rental property or investment home, FloorScore compliance protects you from tenant complaints about "new flooring smell" — which is really off-gassing from adhesives and core materials in products that aren't certified. Installing certified flooring from the start is cheaper than dealing with a dispute later.
If you're renovating a condo and the board has a flooring requirement, FloorScore is almost certainly part of it. Bring the product specification sheet — not just the box label — when you meet with your property manager, because the certification number on the spec sheet is what the board typically checks.
For families with young children, pregnant household members, or anyone sensitive to indoor air quality, GREENGUARD Gold products are worth seeking out. The emission limits for GREENGUARD Gold are set with a safety margin designed to protect the most vulnerable populations.

What to Ask When You're Buying Flooring
Before you finalize any flooring purchase, ask these three questions:
- Does this product have CARB2 certification? (Ask specifically for the MDF core if buying laminate)
- Is this product FloorScore certified? (Particularly important for condo installations)
- Does this product have GREENGUARD or GREENGUARD Gold certification? (Important if anyone in the home has chemical sensitivities or if you're furnishing a childcare space)
If a salesperson can't provide the certification number or a spec sheet that shows the certification, treat that as a red flag. Legitimate certifications are documented — they're not marketing claims. At Top Floorings Depot, our team can pull the certification documentation for any product in stock.
