Greenwashing: Understanding European Regulation and Taking Concrete Action (Expert Guide for SMEs)

Why greenwashing has become a strategic issue

Greenwashing is no longer a simple communication or ethics topic. It has become a major legal, commercial and reputational risk, at the heart of new European sustainability policies.

Long tolerated, vague or unsubstantiated environmental claims are now explicitly regulated by law. For SMEs as for large companies, talking about the environment now engages the company’s responsibility.

This article offers an in-depth, operational analysis of greenwashing:

  • its precise definition,
  • the new European regulatory framework,
  • reference legal sources,
  • and above all the concrete first steps SMEs must put in place.

What is greenwashing? A professional definition

Greenwashing refers to any misleading environmental communication, intentional or not, that gives an exaggerated, vague or unfounded image of the environmental performance of a product, service or organisation.

Contrary to common belief, greenwashing does not rely solely on bad faith. It can result from:

  • incomplete data,
  • fragile methodologies,
  • poorly worded messages,
  • absence of documented evidence,
  • or a gap between communication and actual practices.

Common examples of greenwashing

  • Vague claims (“eco-responsible”, “environmentally friendly”) with no clear definition
  • Unverified self-declarations (“carbon neutral” with no methodology)
  • Internal or unrecognised labels
  • Highlighting a minor positive impact to mask significant ones
  • Unjustified environmental comparisons

Why the regulatory framework has changed

The European Union found that:

  • more than 50% of environmental claims were vague or unsupported,
  • consumers and business customers were being misled,
  • competition was being distorted.

Result: environmental communication is now considered a regulated economic act, on the same footing as financial advertising.

Directive (EU) 2024/825: a major turning point

Adopted in 2024, Directive (EU) 2024/825 aims to strengthen consumer protection against misleading commercial practices, explicitly integrating environmental claims.

Main objectives

  • Prohibit unsubstantiated environmental claims
  • Strictly regulate the use of labels and certifications
  • Strengthen comparability and transparency
  • Hold companies legally accountable

What the directive explicitly prohibits

  • General claims with no proof (“green “, “sustainable“, “eco“)
  • Claims based solely on carbon offsetting
  • Labels not certified by independent schemes
  • Future environmental promises with no credible plan

Timeline

  • Transposition by Member States: no later than 27 March 2026
  • Mandatory application: mid-2026

Link with other European texts (CSRD, ESRS, Taxonomy)

The greenwashing directive does not operate in isolation.

It sits within a coherent regulatory ecosystem comprising:

  • the CSRD (Corporate Sustainability Reporting Directive),
  • the ESRS (European Sustainability Reporting Standards),
  • the European Green Taxonomy.

In practice:

What is communicated must be consistent with what is reported, measured and verifiable.

Concrete risks for SMEs

Greenwashing exposes companies to:

1. Legal risks

  • administrative sanctions
  • fines
  • injunctions to withdraw or correct claims

2. Commercial risks

  • loss of contracts (large corporate clients, buyers)
  • exclusion from tenders
  • deterioration of banking relationships

3. Reputational risks

  • damage to ESG credibility
  • loss of partner trust
  • negative media exposure

What SMEs should prioritise (concrete first steps)

1. Map existing messages

Identify all communications containing environmental messages:

  • website
  • sales brochures
  • responses to client questionnaires
  • social media

2. Link each message to evidence

For each claim:

  • what data?
  • what source?
  • what methodology?
  • what period?

Without evidence, the message becomes a risk.

3. Clarify the maturity level

It is better to say:

“we are in the process of structuring”
rather than over-promising.

4. Put minimal governance in place

Even without a dedicated CSR team:

  • designate an ESG messaging owner
  • define a validation process
  • retain evidence

5. Anticipate verification

Ask a simple question:

“Would we be able to demonstrate this claim before an independent third party?”

Conclusion: speak less, demonstrate better

Greenwashing is no longer a question of intention.

It is now a question of method, evidence and governance.

For SMEs, the challenge is not to be perfect, but to be clear, consistent and credible.

The good news?
A well-structured environmental narrative becomes a sustainable competitive advantage.
