How to Read an Eco Label as a Homeowner
FSC, PEFC, EPD, Blue Angel, EU Ecolabel, Greenguard, Declare, and B Corp without the architect-speak
Why eco labels are confusing
Eco labels do not all measure the same thing. Some check where a material came from, some test indoor air emissions, some publish carbon data, and some assess the company behind the product. A label can be useful and still not answer the question you thought it answered.
For homeowners, the easiest approach is to ask: what claim is this label proving? Responsible timber? Low emissions? Ingredient transparency? Whole-product environmental performance? Once you know the job of the label, it becomes much easier to compare products.
Quick decoder
Use this as a plain-English first pass when you see a logo on paint, timber, flooring, insulation, furniture, or a supplier profile.
| Label | What it is useful for | What it does not prove |
|---|---|---|
| FSC | Timber, paper, and wood products from responsibly managed forests or recycled sources | Low VOCs, low carbon, or chemical safety |
| PEFC | Responsible forestry and chain-of-custody for timber and wood products | Product emissions or embodied carbon |
| EPD | Transparent lifecycle environmental data, especially embodied carbon | That the product is automatically low-impact or healthy |
| Blue Angel | Strict environmental and health criteria for certain product groups, especially indoor products | That every product category is covered |
| EU Ecolabel | A multi-criteria environmental label for products like paints, flooring, and cleaning products | A specific carbon figure |
| Greenguard | Low chemical emissions into indoor air | Where the material came from or how it was made |
| Declare | Ingredient transparency and Red List screening | Low carbon or low emissions by itself |
| B Corp | Company-level social and environmental performance | That every product made by the company is sustainable |
Match the label to the job
The right label depends on what you are buying and where it will be used.
| Topic | Detail |
|---|---|
| Buying timber, plywood, doors, or decking | start with FSC or PEFC. |
| Painting a bedroom, nursery, or home office | look for low-VOC information, Blue Angel, EU Ecolabel, or Greenguard where relevant. |
| Choosing flooring, adhesives, or composite boards | Greenguard, Blue Angel, Declare, and formaldehyde information are more useful than generic green claims. |
| Comparing insulation, concrete, plasterboard, or larger building products | an EPD helps you understand embodied carbon. |
| Choosing between brands with similar products | B Corp or company-level certification can be a tie-breaker, not the whole answer. |
Tip. No single logo means 'this is the best product'. Good choices usually combine the right label, the right material for the job, and enough product information to avoid guesswork.
Green-claim red flags
Some packaging is designed to feel sustainable without proving much. Treat these claims as a prompt to ask for evidence.
Unverifiable certificates
If you can't check it against a public registry, treat it with caution.
Vague origin claims
'Sourced from Europe' without naming countries or factories.
No chain of custody
For timber products, absence of CoC means the source can't be traced.
Recycled content without method
A percentage without stating pre/post-consumer or verification basis.
Defensive responses
A supplier confident in their credentials will share evidence readily.
Unknown EPD programme
EPDs not registered with a recognised programme operator (IBU, BRE, EPD International).
What to check before trusting a label
You do not need to become a certification expert. A few checks catch most weak claims.
1.Declared unit
What quantity does the data refer to? Compare products using the same unit (e.g. per m², per kg, per m³).
2.Lifecycle stages covered
Check which stages are included (A1-A3 is common). An EPD covering only A1-A3 is not comparable to one covering A1-C4.
3.GWP (Global Warming Potential)
The headline carbon number, measured in kg CO₂e. Lower is better, but only compare like-for-like units and scopes.
4.Validity date
EPDs expire - typically after 5 years. They should also be re-issued earlier if the manufacturer changes raw materials, suppliers, or processes in ways that affect the figures.
5.Programme operator and verifier
Look for recognised programme operators (e.g. EPD International, BRE, IBU) and independent third-party verification.
6.Type of EPD
Third-party verified, variant, project, or system-verified - each carries different weight. Self-declared 'environmental statements' are not EPDs.
A homeowner's shortcut
If you only remember one thing, match the label to the risk.
| Topic | Detail |
|---|---|
| Forest impact | FSC or PEFC. |
| Indoor air | Greenguard, Blue Angel, EU Ecolabel, VOC test data. |
| Carbon data | EPD. |
| Ingredient transparency | Declare. |
| Company values | B Corp. |
| Reclaimed or second-hand materials | ask about provenance and condition; labels may be less relevant than inspection. |
Using labels on Matera
On Matera, use certification filters as a shortcut, then open the material profile to check what the label is attached to. A good product page should show the exact certification, certificate number or document, and which product it applies to. If that is missing, ask the supplier before buying or specifying.
