Green Labels, Eco-labels & Anti-greenwashing for SMEs: Which Claim Is Real (2026)

Not every "green" label carries the same weight

On a shelf, a product may bear the words "eco-friendly," a self-drawn leaf icon, or a seal from an independent certifier — and those three do not carry the same legal weight. For an SME differentiating on sustainability, misreading this leads to two risks: (1) paying for a certification you don't need, or (2) slapping on a "green" claim with no basis — and running into the law.

The framework already exists: the international standard series ISO 14020 splits environmental labels and declarations into three types (Type I, II, III), differing in who verifies and on what evidence (Hedgehog).

CP TRẠM NĂNG LƯỢNG SỐ view: for an SME the right question is not "which fancy green label to get" but "how far can I actually back up my claim." Claim exactly as far as your evidence reaches — that is both brand ethics and legal armor.

The three ISO environmental label types

Table 1 — Three environmental label types under ISO 14020

Type	Standard	Verified by	Based on	Example / used for
Type I — Ecolabel	ISO 14024	Independent third party	Pass–fail criteria across the product life cycle	EU Ecolabel, Vietnam Green Label; consumer goods needing simple guidance
Type II — Self-declared claim	ISO 14021	The company itself (no third party required)	Company's own responsibility; must substantiate with data on request	"Made from 100% recycled plastic"; single claims on packaging/ads
Type III — Product declaration (EPD)	ISO 14025	Third-party-verified LCA	Quantified Life Cycle Assessment per Product Category Rules	Building-material EPDs; B2B contexts needing detailed data

The crux: Type I says "this product beats a criterion"; Type III just reports numbers without judging good/bad; Type II is the company talking about itself (Hedgehog; Agoria). A third-party Type I seal therefore carries far more weight with consumers than a self-applied Type II claim.

What Vietnam's Green Label is, and who issues it

Vietnam runs an official eco-labelling programme called "Nhãn xanh Việt Nam" (Vietnam Green Label) — essentially a Type I label (third-party, life-cycle criteria):

Table 2 — Vietnam Green Label: key facts

Item	Detail
Origin	Approved in 2009 via Decision 253/QĐ-BTNMT dated 5 March 2009 (Ministry of Natural Resources & Environment, MONRE)
Current legal basis	Environmental Protection Law 2020 (Article 145) — environmentally-friendly products/services; detailed by Decree 08/2022/NĐ-CP
Who certifies	The competent authority (MONRE / environment agency) — i.e. a state third party, not the company self-labelling
Criteria basis	Assesses the full life cycle: raw-material extraction → production → distribution → use → disposal/recycling, causing less environmental harm than similar products
Certificate validity	36 months from date of issuance
Processing time (reference)	Checks the dossier's completeness within 05 days; assesses and certifies within 30 days of receiving a complete, valid dossier (Decree 08/2022, Article 147)

Type II — the trap of the "self-declared" claim

Most SME "green" claims on packaging and ads are Type II — self-declared. ISO 14021 permits this but places the burden of proof on the company: the claim must be specific, unambiguous, and backed by verifiable data when an authority or customer asks (Hedgehog).

Claims that easily become greenwashing: vague "eco/environmentally friendly" with no scope; "carbon neutral"/"net zero" with no boundary or method; fake third-party-looking seals; and half-true claims that hide the rest. In Vietnam, legal practitioners warn that even without a dedicated anti-greenwashing law, such claims can already be pursued under the Advertising Law, Competition Law and Consumer Rights Protection Law (Russin & Vecchi).

The anti-greenwashing legal frame — Vietnam & EU

Table 3 — Legal boundaries for "green" claims

Instrument	Applies in	Key point
Consumer Rights Protection Law 2023 (No. 19/2023/QH15)	Vietnam	Passed 20 Jun 2023, effective 1 Jul 2024. Prohibits false, incomplete or misleading information; businesses must ensure complete, accurate info (Art. 10, Art. 21) — LuatVietnam
Advertising Law 2012 + Competition Law 2018	Vietnam	Prohibit misleading advertising about features/effects; the basis for pursuing false "green" claims absent a dedicated greenwashing law — Russin & Vecchi
Environmental Protection Law 2020 + Decree 08/2022	Vietnam	Defines environmentally-friendly products/services & the eco-label certified by the competent authority (Art. 145) — "environmentally friendly" must be recognised, not self-proclaimed — Luật Môi Trường
EU — "Empowering Consumers for the Green Transition"	Exports to the EU	Adopted early 2024, applies from 27 Sep 2026; bans generic "eco-friendly" and "climate neutral"/"net zero" claims unless substantiated — ClimatePartner
EU — Green Claims Directive (proposal)	Exports to the EU	Proposed Mar 2023 (ex-ante verification). Jun 2025 the Commission announced intent to withdraw, talks cancelled 23 Jun 2025 — status uncertain, but the EmpCo frame above still stands — Latham & Watkins

Even while the EU debates the Green Claims Directive, the tightening of environmental claims does not disappear — the "Empowering Consumers" directive is locked in from 27 Sep 2026. EU-exporting SMEs should build evidence for every "green" claim now.

Which certification for which SME

• B2C retail SME whose product has a Green Label criteria set → pursue Vietnam Green Label (Type I) for a credible third-party seal.
• SME with no criteria set yet, or making one specific attribute claim (e.g. recycled content) → use a Type II claim — but write it specifically, with scope, and keep the substantiating data on file.
• B2B / industrial SME (construction, packaging, components) → consider an EPD (Type III, ISO 14025) since business buyers need LCA numbers to compare.
• EU-exporting SME → align to the EU "Empowering Consumers" rules (from 27 Sep 2026): drop generic claims, standardise evidence.

Five rules to keep a "green" claim lawful

1. Be specific and scoped — say which stage, which attribute, versus what; avoid bare "eco / environmentally friendly."
2. Keep filed evidence — every Type II claim needs data/method producible on request.
3. Never fake a third-party seal — use a certification logo only if actually granted (Vietnam Green Label, EU Ecolabel…).
4. Keep marketing consistent with reality — ad claims must match the technical file and product label; a mismatch is a liability under the Consumer Rights Law 2023.
5. Handle "carbon neutral"/"net zero" carefully — claim only with a stated boundary and method; this is the most tightly regulated claim in both Vietnam and the EU.

For that reason this article asserts no specific product to be "green" or Green-Label-eligible — that depends on each product group's criteria and on real data supplied by the business and assessed by the competent authority.
