Sustainable packaging claims in 2026: 8 greenwashing patterns to avoid (with real brand examples)

1Vague "eco-friendly," "green," or "sustainable" language

What it looks like: "Eco-friendly packaging," "our sustainable solution," "green choice," "environmentally responsible" — generic claims without measurable criteria.

Why it's targeted: The 2022 amendment to the EU Unfair Commercial Practices Directive explicitly blacklisted generic environmental claims that cannot be substantiated. These claims are now per se misleading under EU law — meaning regulators don't need to prove consumer deception, only that the claim cannot be verified.

Real example: France's JEP (Jury de Déontologie Publicitaire) ruled against multiple consumer goods brands in 2024-2025 for using "green" and "sustainable packaging" labels without specific metrics. One home care brand was ordered to remove "sustainable packaging" from its label because no lifecycle assessment was provided to support the claim.

Compliant alternative: Replace generic claims with specific, measurable ones: "Made with 30% recycled content" or "Packaging carbon footprint reduced by 28% vs 2020 baseline (verified by Bureau Veritas)."

2Misleading "recyclable" claims where collection infrastructure is limited

What it looks like: "100% recyclable packaging," "fully recyclable," "recyclable" (without qualification) when the packaging type is not collected in most municipal recycling schemes.

Why it's targeted: A packaging material being technically recyclable in specialist facilities does not make a consumer-facing "recyclable" claim truthful. The Netherlands' ACM and UK's ASA have both established that "recyclable" implies accessibility — the material must be recyclable in collection infrastructure available to the majority of consumers who will buy the product.

Real example: A major UK snack brand was required by the ASA to stop claiming its crisp bags were "fully recyclable" because, while the material was technically recyclable, the take-back scheme required consumers to travel to specific retail locations — not a standard kerbside collection. The "fully recyclable" claim was found to mislead consumers about practical accessibility.

Compliant alternative: "Recyclable at large supermarket carrier bag collection points — not kerbside recyclable" or "Recyclable where facilities exist — check at recyclenow.com."

3Unverified "bio-based" or "plant-based" claims without percentage specification

What it looks like: "Bio-based packaging," "made from plants," "plant-derived" without specifying what percentage of the material is bio-based and from which sources.

Why it's targeted: A packaging material containing 5% bio-based content is not meaningfully "bio-based" in the way consumers understand the term. German courts and the Wettbewerbszentrale have ruled against packaging claims that implied full bio-based composition when only a minority of the material originated from plant sources. Dutch ACM investigations have followed the same logic.

Compliant alternative: State the actual percentage: "Contains 35% bio-based content derived from sugarcane (EN 16785-1 certified)." Third-party certification (TÜV Austria OK biobased, DIN CERTCO) adds significant legal defensibility.

4Offset-based "carbon neutral" packaging claims

What it looks like: "Carbon neutral packaging," "climate neutral," "net-zero packaging" based primarily or entirely on purchased carbon offset credits rather than actual emissions reductions in the packaging production process.

Why it's targeted: Following the TotalEnergies precedent (see our EU greenwashing enforcement cases analysis), offset-based carbon neutrality claims are increasingly treated as misleading across sectors. France's ADEME published specific guidance in 2023 restricting the term "carbon neutral" in advertising to products that have achieved verified operational emissions reductions — not just offsetting.

Real example: A major French food brand was ordered by ADEME in 2024 to remove "carbon neutral product" labelling from a product whose neutrality claim was based 100% on rainforest offset credits, with no documented reduction in manufacturing or packaging emissions.

Compliant alternative: "Packaging emissions reduced by 40% vs 2020 baseline; residual emissions offset via Gold Standard projects (verification report available at [URL])."

5Misleading green imagery and nature symbols

What it looks like: Green-coloured packaging, leaf logos, tree imagery, and nature photographs used on packaging with no intrinsic environmental benefit — or minimal benefit disproportionate to the visual messaging.

Why it's targeted: The aggregate impression test — established in the Shein ruling and multiple national advertising cases — means a packaging design can constitute greenwashing even when no explicit environmental claim is made. If the visual design creates an overall impression of sustainability that the product's actual environmental profile does not support, it is regulatorily non-compliant.

What this means in practice: A conventional plastic detergent bottle with green leaf imagery on the label, no verified environmental claims, and no third-party certification creates an implicit green claim through its design — and that implicit claim is subject to the same substantiation requirements as explicit text claims.

6"Compostable" without specifying conditions

What it looks like: "Compostable packaging," "compostable" (unqualified), "breaks down naturally" when the material is industrial-compostable only and will not biodegrade in home compost or landfill conditions.

Why it's targeted: Industrial composting requires temperatures of 55-70°C and specific microbial conditions not present in garden compost bins or standard waste management. "Compostable" packaging that ends up in landfill or ocean does not decompose as consumers expect, and the claim creates a misleading impression about disposal. France's AGEC law (2020) and subsequent implementing decrees restrict compostability claims on packaging to certified industrially compostable materials, with mandatory disposal instructions.

Compliant alternative: "Industrially compostable — discard with food waste if your local authority collects food waste. Not suitable for home composting." If the material is EN 13432 certified for industrial composting, specify the certification.

7"Reduced plastic" without baseline or percentage

What it looks like: "Less plastic," "reduced plastic content," "lighter packaging" without stating compared to what, by how much, and over what time period.

Why it's targeted: Comparative claims require an explicit and verifiable baseline. "Less plastic than before" is meaningless without specifying the previous product version and the reduction percentage. The UK's CMA Green Claims Code (2021) and France's ADEME guidance both explicitly require comparative claims to identify the comparison baseline. These have been used in enforcement actions by both competition authorities.

Compliant alternative: "Packaging plastic content reduced by 35% vs our 2021 pack (from 24g to 15.6g per unit), verified against our production specifications."

8Unverified "sustainable sourcing" claims without third-party certification

What it looks like: "Sustainably sourced paper/cardboard/wood," "responsible forestry," "sustainably managed materials" without FSC, PEFC, or equivalent third-party certification.

Why it's targeted: Supply chain sustainability claims are impossible for consumers to verify independently, making third-party certification the minimum standard regulators expect. Company self-declarations of "sustainable sourcing" are treated by most national enforcement authorities as inherently unverifiable and therefore misleading when used without certification logos. Germany's courts have been particularly active in requiring third-party substantiation for supply chain environmental claims.

Compliant alternative: Use FSC-Certified or PEFC-Certified logos with the certification code, which allows verification at the scheme's public registry. If your packaging board is FSC Mix or FSC Recycled, state this explicitly alongside the logo.
