A Beginner's Guide to Eco Labels

One logo does not mean everything

Eco labels are useful, but they answer different questions. FSC does not mean low-VOC. Greenguard does not mean low carbon. B Corp does not mean every product is perfect.

For beginners, the important thing is not memorising every certification. It is learning which label helps with which decision. A timber shelf, a nursery paint, a carpet adhesive, and a concrete block all need different kinds of evidence.

Plain-English label guide

This is the quick version.

Topic	Detail
FSC and PEFC	Better forestry and timber sourcing.
EPD	Environmental data, especially carbon, but not a pass/fail eco badge.
Greenguard	Low chemical emissions into indoor air.
Blue Angel	Strict health and environmental criteria for certain product types.
EU Ecolabel	Multi-criteria environmental label for some consumer and fit-out products.
Declare	Ingredient transparency and Red List screening.
B Corp	Company-level social and environmental performance.

Match the label to the risk

Start with the thing you are worried about, then look for the label that answers that worry.

If you care about...	Look for	Useful for
Forest sourcing	FSC or PEFC	Timber, plywood, doors, decking, paper-based boards
Indoor air	Greenguard, Blue Angel, EU Ecolabel, VOC test data	Paints, flooring, adhesives, furniture, boards
Carbon data	EPD	Insulation, concrete, plasterboard, flooring, larger products
Ingredients	Declare or HPD	Interior finishes and products for sensitive rooms
Company behaviour	B Corp or similar company-level evidence	Choosing between brands with similar products

What to check

Before trusting a claim, check whether the label applies to the exact product, whether it is current, and whether it covers your concern: forests, air, carbon, ingredients, or company behaviour.

Three example decisions

The easiest way to use labels is to match them to a real purchase rather than treating them like a ranking table.

You are buying	Most useful evidence	Less useful on its own
Timber shelves	FSC or PEFC for timber sourcing, plus finish guidance	A vague natural claim
Paint for a child's bedroom	Low emissions evidence such as Greenguard, Blue Angel, EU Ecolabel, or VOC data	A green colour palette or plant imagery
Insulation or boards	EPD for carbon data, plus fire, moisture, and installation data	A company sustainability statement only

How not to overthink it

For a small DIY project, labels are a decision aid, not homework for the sake of it. Pick the main risk, check the relevant evidence, then move on to suitability, cost, availability, and whether you can install and maintain the product correctly.

For timber, start with responsible sourcing.
For interior finishes, start with indoor air and cleaning.
For large quantities of heavy materials, start with carbon data if available.
For sensitive rooms, look harder at ingredients and emissions.
For two similar products, company-level labels can help break the tie.

Green-claim red flags

Some packaging looks sustainable without proving much. These are signs to slow down and ask for evidence.

A leaf icon with no named certification.
Words like eco, natural, green, planet-friendly, or non-toxic without a certificate or test.
A company award used to imply every product is certified.
A certificate with no number, date, product name, or public listing.
Recycled content claims without a percentage.
Carbon neutral claims that do not show the product's actual impact.

Using labels on Matera

Use Matera certification filters as a shortcut, then open the material profile to check what the label is attached to. Look for the certificate name, document, scope, and product match. If the listing is unclear, ask the supplier before buying.
