September Is Coming: What the EU Green Claims Ban Means for Your Product Marketing

For years, environmental marketing has operated in a relatively comfortable grey zone.

Terms such as “green,” “eco-friendly,” “climate neutral,” and “sustainable” appeared on packaging, websites, advertisements, and product pages across Europe with varying levels of evidence behind them. In many cases, companies relied on broad sustainability narratives, carbon offset programmes, or internally developed environmental labels without facing significant regulatory consequences.

That era is ending.

From 27 September 2026, the European Union’s Empowering Consumers for the Green Transition Directive (ECGT) becomes fully applicable across all Member States. The new rules fundamentally change what companies can say about the environmental performance of their products and services.

The deadline is now less than four months away.

More importantly, enforcement is no longer theoretical. Italy has already seen the first courtroom test of its transposed legislation. Germany has completed transposition. France is proposing some of the most aggressive penalties in Europe, including fines that could reach up to 80% of advertising expenditure linked to unlawful environmental claims.

For companies selling products into EU markets, the question is no longer whether to prepare.

The question is whether there is still enough time.

The Biggest Change: Generic Green Claims Are No Longer Safe

One of the most significant aspects of the ECGT framework is its treatment of generic environmental claims.

Statements such as:

• “Environmentally friendly”
• “Eco-friendly”
• “Green”
• “Sustainable”
• “Climate friendly”
• “Good for the planet”

will no longer be permissible unless they can be supported by recognised, verifiable evidence demonstrating excellent environmental performance.

This represents a fundamental shift in regulatory thinking.

Historically, regulators typically focused on whether a claim was objectively false. Under the new framework, a claim can become problematic simply because it is too broad, too vague, or insufficiently substantiated.

Many marketing departments have spent years developing campaigns around precisely these types of phrases.

That makes the compliance challenge much larger than many organizations currently realize.

Carbon Neutral Claims Are Entering Dangerous Territory

Perhaps the most disruptive element of the new regime concerns carbon neutrality claims.

Under the ECGT framework, environmental claims based solely on greenhouse gas offsetting schemes are effectively prohibited.

This affects language such as:

• “Carbon Neutral”
• “CO₂ Neutral”
• “Climate Neutral Product”
• “Net Zero Product”
• “Zero Impact Product”

where the claim is based primarily on the purchase of carbon credits rather than actual reductions across the value chain.

The European Commission’s position is increasingly clear:

Offsetting may contribute to climate strategies, but it cannot be used as the primary basis for presenting a product as environmentally neutral.

For companies that have relied heavily on offset-driven marketing, this could require substantial changes to packaging, advertising, websites, and product descriptions.

Sustainability Labels Are Also Under Scrutiny

Another area receiving significant regulatory attention is environmental labels and trust marks.

Many companies have developed proprietary sustainability badges over the years, including:

• Internal “green choice” labels
• Company-created eco seals
• Marketing-generated sustainability icons
• Custom ESG certification schemes

Under the new framework, sustainability labels must generally be based on recognised certification systems or established by public authorities.

Self-created environmental labels face increasing regulatory risk.

Organisations should assume that every environmental badge appearing on packaging or digital channels will be scrutinised.

Italy Has Already Fired the Warning Shot

Italy’s Legislative Decree 30/2026 has become one of the first real-world tests of the ECGT framework.

The country’s early enforcement activity demonstrates that regulators are not waiting until September to begin examining environmental claims.

What makes Italy particularly important is not simply that it acted first.

It is that it provides insight into how authorities across Europe are likely to approach enforcement once the deadline arrives.

The emerging pattern is clear:

Regulators are increasingly interested in whether companies can prove environmental claims rather than simply whether they intended to mislead.

That may sound like a subtle distinction.

In practice, it dramatically expands enforcement risk.

Why Multinationals Face an Even Bigger Challenge

Many organizations are approaching ECGT compliance as if it were a single European requirement.

The reality is more complicated.

The directive creates harmonised rules, but enforcement remains national.

This means a company could face:

• Investigation in multiple jurisdictions
• Different enforcement authorities
• Different procedural requirements
• Different penalty structures

The result is a phenomenon many legal teams are calling “penalty stacking.”

A problematic environmental claim appearing across multiple EU markets may potentially trigger investigations from several authorities simultaneously.

France’s proposed penalty framework illustrates why this matters.

If implemented as currently proposed, sanctions could reach levels that far exceed what many companies traditionally associate with marketing compliance violations.

Environmental claims are increasingly being treated with the seriousness regulators historically reserved for consumer protection and financial disclosure issues.

The Compliance Checklist Every Company Should Be Running Now

With September approaching rapidly, organisations should already be conducting a comprehensive review of environmental marketing materials.

1. Inventory Every Environmental Claim

Start by identifying all environmental statements across:

• Product packaging
• Websites
• E-commerce listings
• Advertisements
• Social media content
• Product brochures
• Sustainability reports used for marketing purposes

Many companies discover hundreds of environmental references once a full audit begins.

2. Identify High-Risk Language

Flag phrases such as:

• Green
• Eco-friendly
• Sustainable
• Carbon neutral
• Climate neutral
• Environmentally responsible
• Net zero product

These are among the most likely to attract regulatory attention.

3. Review Supporting Evidence

For every claim, ask:

• What evidence supports this statement?
• Is the evidence independently verifiable?
• Is the methodology documented?
• Can the evidence be produced quickly if challenged?

If the answer is unclear, the claim likely requires review.

4. Examine Sustainability Labels

Create an inventory of every environmental seal, badge, icon, or certification displayed on products or websites.

Determine:

• Who created it?
• What criteria support it?
• Is it independently certified?
• Would a regulator recognise it as a legitimate certification scheme?

Many internally developed labels will require modification or removal.

5. Reassess Carbon Neutrality Communications

Organizations using offsets should carefully distinguish between:

• Actual emissions reductions
• Decarbonisation initiatives
• Carbon credit purchases
• Long-term climate goals

The safest approach increasingly involves transparency rather than broad neutrality claims.

6. Establish Governance Around Claims

Environmental marketing can no longer remain solely a marketing function.

Leading organizations are creating formal review processes involving:

• Sustainability teams
• Legal departments
• Compliance officers
• Product teams
• Marketing leadership

Every environmental claim should have a documented owner and evidence trail.

The Bigger Shift: Environmental Marketing Is Becoming Regulated Infrastructure

Many companies still view sustainability claims as a communications issue.

Regulators increasingly do not.

The direction of travel is unmistakable.

Environmental claims are becoming regulated business infrastructure requiring:

• Documented methodologies
• Traceable evidence
• Governance controls
• Independent verification
• Ongoing monitoring

This mirrors the broader evolution already occurring in ESG reporting, where regulators are moving away from aspirational narratives and toward demonstrable, auditable information.

Organizations that build systems capable of maintaining evidence, validation records, governance workflows, and traceable sustainability data will be significantly better positioned than those relying on manual spreadsheets and disconnected documentation.

September Is Closer Than It Looks

The most dangerous assumption companies can make today is that September 2026 remains a distant compliance milestone.

It does not.

Italy’s early courtroom activity demonstrates that regulators are already testing the boundaries of the new framework. Germany has completed transposition. France is preparing aggressive enforcement tools. Authorities across Europe are building enforcement capacity.

The companies that begin auditing claims today will have time to adjust.

The companies that wait until autumn may discover that packaging has already been printed, campaigns have already been launched, and regulators have already started asking questions.

September is coming.

And for environmental marketing in Europe, it represents one of the biggest rule changes in decades.
