Italy's 2026 Greenwashing Rules Explained: What Advertisers Must Do Now

Italy’s greenwashing law has entered a new era. Legislative Decree No. 30/2026 (D. Lgs. 30/2026), published on 20 February 2026 and transposing the EU Green Claims Directive (Directive 2024/825), imposes strict substantiation and transparency obligations on every business making environmental claims in commercial communications directed at Italian consumers. Courts are already enforcing the new framework, an Italian court issued an injunction in May 2026 against advertising that misrepresented an environmental certification. For marketing teams, in-house counsel and agency compliance officers, the message is clear: audit every green claim in your portfolio now, or face fines, injunctions and reputational damage.

Executive Summary: Key Takeaways for Advertisers

Before diving into the detail, here are the essential points that every brand and agency operating in Italy needs to understand about greenwashing law Italy compliance in 2026:

• New national rules are in force. D. Lgs. 30/2026 transposes EU Directive 2024/825 into Italian law, amending the Consumer Code to specifically target misleading environmental claims.
• Generic green claims are now presumptively misleading. Vague phrases such as “eco-friendly,” “green,” “sustainable” or “climate-neutral” are prohibited unless backed by robust, verifiable evidence specific to the product or service.
• Substantiation is mandatory before publication. Advertisers bear the burden of proof. Evidence, including lifecycle assessments, third-party test reports and supply-chain attestations, must exist before a claim goes live.
• Certification and label claims face heightened scrutiny. Displaying environmental seals, logos or certification marks in advertising is restricted to labels that meet independence and verification criteria set out in the decree.
• Enforcement is already active. An Italian court enjoined the advertising of an environmental certification as greenwashing in a ruling reported on 11 May 2026, signalling that regulators and private litigants are moving quickly.
• Multiple enforcement routes exist. The AGCM (Italian Competition Authority), national courts and consumer organisations can all initiate proceedings, and competitors may bring unfair competition actions.
• Immediate action is required. Brands should conduct a full audit of existing advertising assets, update internal approval workflows, secure substantiation documentation, and retrain creative and media teams.

Legal Framework: What DLgs 30/2026 Implements and How It Fits EU Rules

D. Lgs. 30/2026 is Italy’s national transposition of EU Directive 2024/825, which amended the Unfair Commercial Practices Directive and the Consumer Rights Directive to specifically address environmental and social claims in business-to-consumer communications.

From Brussels to Rome: The Transposition Path

The EU adopted Directive 2024/825 to establish a harmonised floor of rules preventing misleading environmental claims across all member states. Italy published its implementing decree, Legislative Decree No. 30/2026, in the Gazzetta Ufficiale on 20 February 2026. The decree entered into force on 24 March 2026, making all obligations immediately binding on traders targeting Italian consumers.

The green claims decree Italy now implements operates by amending the existing Italian Consumer Code (Codice del Consumo, D. Lgs. 206/2005). This means that misleading environmental claims are not treated under a separate, standalone regime but are instead folded into Italy’s well-established unfair commercial practices framework, with all the procedural and enforcement machinery that accompanies it.

Key Definitions Advertisers Must Know

The decree introduces or clarifies several definitions that directly affect advertising copy:

• Environmental claim. Any message, whether in text, imagery, graphics, logos, brand names or product labelling, that suggests or creates the impression that a product or trader has a positive environmental impact, is less damaging than alternatives, or has improved its environmental performance over time.
• Generic environmental claim. A claim that refers to environmental performance in broad, unqualified terms (e.g., “green,” “eco,” “sustainable”) without specifying the precise aspect of performance being claimed.
• Comparative environmental claim. A claim that directly or implicitly compares the environmental characteristics of one product with those of another product, a previous version, or a competitor.
• Sustainability label. Any voluntary trust mark, quality mark, or label that purports to certify environmental characteristics and is displayed in commercial communications.

Timeline of Key Legislative Dates

What Is Prohibited or Requires Proof: Red Flags for Advertisers Under Greenwashing Law Italy

Under D. Lgs. 30/2026, any environmental claim that is unsubstantiated, misleading or ambiguous is treated as an unfair commercial practice. The greenwashing advertising rules target several distinct categories of risk.

High-Risk Claim Types

• Generic green claims without qualification. Saying a product is “eco-friendly” or “sustainable” with no further explanation is now presumptively misleading. The decree requires that any general claim be accompanied by a clear, prominent explanation of the specific environmental aspect to which it relates.
• Unverified certification or label claims. Displaying a sustainability logo or certification mark that does not meet the decree’s independence and verification criteria constitutes a misleading action. The May 2026 court injunction demonstrates how seriously this category is being treated.
• Claims based on regulatory compliance alone. Advertising a product as “environmentally friendly” solely because it complies with mandatory legal requirements (e.g., REACH, RoHS) is misleading, the claim implies the product exceeds baseline standards when it does not.
• Future performance claims without a plan. Promising future environmental improvements, “we will be carbon-neutral by 2030”, without a detailed, publicly accessible and independently verified implementation plan is prohibited.
• Comparative claims without a fair basis. Claiming superiority over a competitor’s product requires that the comparison use equivalent data, methodologies and scope. Cherry-picking favourable metrics is a red flag.
• Material omissions. Highlighting one positive environmental attribute while concealing a significant negative impact (such as high water consumption) makes the overall impression misleading.

Permitted Claim Framing (With Caveats)

Not all environmental messaging is banned. Claims that are specific, substantiated and clearly communicated remain lawful. Below are sample framings that industry observers expect would satisfy the decree’s requirements:

• Instead of: “Our packaging is sustainable.” Consider: “This carton is made from 85% post-consumer recycled cardboard, verified by [named certification body] in [month/year].”
• Instead of: “Climate-neutral product.” Consider: “This product’s manufacturing emissions have been reduced by 40% since 2022. Remaining emissions are offset through [named, verified scheme]. Full methodology available at [URL].”
• Instead of: “Eco-friendly formula.” Consider: “This formula contains no phosphates and is 92% biodegradable within 28 days under OECD 301B test conditions.”

The common thread: specificity, quantification and a transparent evidence trail.

Environmental Claims Substantiation: Evidence Types, Documentation and Burden of Proof

Under the green claims decree Italy, the burden of proving that an environmental claim is truthful, specific and not misleading rests entirely on the trader making the claim. Substantiation must exist before a claim is published, not assembled retroactively after a challenge.

What Counts as Adequate Evidence

The type of evidence required depends on the nature of the claim. The following evidence matrix provides practical guidance:

How to Document: Retention, Audit Trail and File Management

Substantiation is only useful if it can be located, presented and defended quickly. Industry best practice, and the likely practical expectation of regulators and courts, calls for the following documentation standards:

• Pre-publication file. For every green claim in an advertisement, create a dedicated substantiation file before the asset goes live. The file should contain the claim text, the evidence relied upon, the date of evidence, the name of the verifier and a risk-rating score.
• Retention period. While D. Lgs. 30/2026 does not specify a single mandatory retention period for all evidence, advertising compliance in Italy typically requires that substantiation be retained for the duration the claim is in circulation plus a reasonable buffer period. Industry observers recommend a minimum of five years from last use of the claim to account for potential enforcement actions and limitation periods under Italian civil law.
• Audit trail. Maintain a version-controlled log of every green claim, its approval date, the identity of the approving officer, and any subsequent amendments. This is critical for demonstrating good faith in the event of a challenge.
• File naming convention. Use a standardised naming convention that identifies the product, the claim category, the market, the approval date and the version number, for example: ProductX_RecycledContent_IT_20260315_v1.pdf.

Advertising Compliance Italy: Internal Workflow and Green Claims Checklist

Compliance with the greenwashing advertising rules is not a one-off legal review, it requires an embedded workflow that touches creative development, legal sign-off, media buying and post-launch monitoring. This section provides a step-by-step green claims checklist for marketing and legal teams.

Pre-Launch Audit

1. Inventory all active claims. Conduct a full audit of every environmental claim across all channels: packaging, digital ads, social media, POS materials, influencer briefs, press releases and corporate websites.
2. Classify each claim. Categorise claims as generic, specific-quantified, comparative, label-based or future-commitment. Flag all generic claims for immediate review or removal.
3. Match claims to evidence. For each claim, locate the substantiation file. If no file exists, pause the claim and commission the necessary evidence.
4. Assess label and certification validity. Verify that every displayed sustainability label meets the decree’s independence, third-party verification and scope requirements.
5. Check prominence and context. Ensure that qualifications, limitations and conditions are displayed with the same prominence as the headline claim, footnotes in tiny text will not satisfy the decree.
6. Assign a risk score. Rate each claim on a scale (e.g., low / medium / high) based on the strength of evidence, the specificity of the claim and the likely consumer perception. Escalate all high-risk claims to legal counsel before publication.

Approved Claim Templates

To reduce approval bottlenecks, in-house legal teams should develop a library of pre-approved claim templates that creative teams can populate with verified data points. Examples:

• Recycled content template: “This [product/packaging] contains [X]% [post-consumer/post-industrial] recycled [material], certified by [certification body] (certificate no. [XX], valid until [date]).”
• Emissions reduction template: “We have reduced [scope 1/scope 2/scope 3] emissions from [process] by [X]% compared to our [year] baseline, measured in accordance with [standard]. Full methodology: [URL].”
• Certification display template: “[Logo] This product is certified under the [scheme name], an independent third-party certification programme accredited by [body]. Certification scope: [brief description]. Certificate valid: [dates].”

Templates should be reviewed at least annually and updated whenever the underlying evidence is refreshed.

Approval Matrix and Crisis Response Checklist

A clear internal approval matrix prevents green claims from reaching market without adequate review:

• Low-risk claims (specific, quantified, strong evidence): marketing manager approval with legal notification.
• Medium-risk claims (comparative, label-based): joint marketing and legal counsel approval required.
• High-risk claims (generic, future commitments, first-use claims): mandatory sign-off by senior legal counsel or external advertising law specialist.

If a claim is challenged, whether by a consumer complaint, a competitor letter, an AGCM inquiry, or media scrutiny, activate the crisis response protocol immediately:

1. Pause all media placements and digital ads featuring the challenged claim within 24 hours.
2. Preserve all evidence, including internal communications, approval records and the substantiation file.
3. Convene legal, marketing and corporate communications to assess the strength of the claim’s evidence base.
4. Engage specialist regulatory counsel with experience in Italian advertising law before responding to any authority or counterparty.
5. Prepare a draft response or voluntary corrective statement, depending on the severity of the challenge.

Enforcement, Penalties, Remedies and Recent Case Law Under Greenwashing Law Italy

Enforcement of D. Lgs. 30/2026 operates through multiple channels, administrative, judicial and private, each carrying different procedural dynamics and risk profiles for advertisers.

Who Enforces and Who Can Sue

Three principal enforcement routes exist under the Italian framework:

Recent Enforcement Example: The May 2026 Court Injunction

The practical risk is not theoretical. On 11 May 2026, the Library of Congress Global Legal Monitor reported that an Italian court enjoined the advertising of an environmental certification, finding it constituted greenwashing. The court determined that the manner in which the certification was presented in advertising created a misleading impression about the product’s environmental characteristics, and ordered the immediate cessation of the campaign. Early indications suggest this ruling will embolden both regulators and private litigants to pursue further enforcement actions, particularly against unverified or overstated label claims.

IP and Competition Intersections: When Environmental Claims Trigger Trademark or Unfair Competition Claims

Misleading environmental claims do not only expose advertisers to consumer protection liability. They can also trigger intellectual property and unfair competition disputes, an often-overlooked risk.

When to Involve IP Counsel

Several scenarios require coordination between advertising compliance and IP legal teams:

• Unauthorised use of certification marks. Displaying a sustainability logo or certification trade mark without a valid licence, or after a licence has expired, constitutes trade mark infringement in addition to a misleading commercial practice.
• Competitor “green” passing off. If a brand’s environmental claims create confusion with a competitor’s genuinely certified products, the competitor may bring an action for unfair competition under Articles 2598–2601 of the Italian Civil Code, seeking injunctive relief and damages.
• Comparative advertising pitfalls. Comparative green claims that denigrate a competitor’s product without an objective, verifiable evidentiary basis can give rise to both unfair commercial practice proceedings and tortious denigration claims.
• Trade dress and green branding. Adopting colour schemes, imagery or design elements (e.g., extensive use of green, leaf motifs, nature imagery) that are distinctively associated with a competitor’s genuinely eco-certified product line may constitute passing off or trade dress infringement.

The likely practical effect is that in-house counsel will need to involve IP specialists earlier in the creative approval process, particularly for campaigns that reference certifications or draw comparisons with competitors.

Sector Examples and Practical Templates

The impact of greenwashing law Italy varies by sector. Common claim types, substantiation requirements and risk levels differ significantly across industries.

FMCG (Fast-Moving Consumer Goods)

FMCG advertisers frequently use recycled packaging claims, biodegradability assertions and “natural ingredient” messaging. Under D. Lgs. 30/2026, each of these requires product-specific, quantified evidence. A detergent brand claiming “biodegradable formula,” for instance, must hold test results under a recognised standard (such as OECD 301B) and disclose the percentage of biodegradability and the test conditions. Stating merely that a product is “natural” without specifying which ingredients are natural, their proportion and the standard used is a high-risk generic claim.

Fashion and Textiles

Fashion brands face particular scrutiny around “sustainable collection” claims, organic fibre content and carbon-neutral garment assertions. The decree demands that if a brand promotes a “sustainable line,” it must explain precisely what makes it sustainable, recycled fibres, reduced water usage, fair-trade sourcing, with verifiable data. Claims about organic content require chain-of-custody certification (e.g., GOTS, OCS). Carbon neutrality claims for individual garments demand a product-level lifecycle assessment, not merely a corporate-level offset programme.

iGaming and Digital Services

While environmental claims are less common in the iGaming sector, operators promoting “green” data centres, carbon-neutral platforms or sustainability-linked sponsorships are now caught by the advertising compliance Italy rules. Any claim about the environmental performance of digital infrastructure must be substantiated with data-centre energy certificates, power usage effectiveness (PUE) metrics and, where offsets are relied upon, details of the offset scheme’s verification and registry. Industry observers expect scrutiny in this sector to increase as ESG commitments become more prominent in corporate communications by companies operating in Italy.

Quick Remediation Playbook After a Notice or Enforcement Action

If your organisation receives an AGCM inquiry, a competitor cease-and-desist letter, or a court summons relating to alleged misleading environmental claims, act swiftly and methodically:

1. Pause immediately. Suspend all advertising placements that contain the challenged claim across every channel, digital, print, OOH, social, influencer and POS, within 24 hours of receiving notice.
2. Preserve everything. Issue a litigation hold to preserve all documents, emails, Slack messages, creative briefs and approval records related to the claim.
3. Assemble the substantiation file. Locate and compile all pre-existing evidence supporting the claim. Identify any gaps in the documentation.
4. Engage specialist counsel. Appoint or consult regulatory and advertising law counsel with specific experience in Italian consumer protection and AGCM proceedings.
5. Prepare a response strategy. Depending on the nature of the challenge, options may include voluntary corrective action (which can mitigate penalties), formal submissions to the AGCM, or defence of proceedings before the courts.
6. Communicate internally. Brief senior management and align corporate communications messaging to avoid any public statements that could prejudice the legal position.

Conclusion

The introduction of D. Lgs. 30/2026 marks a fundamental shift in how greenwashing law Italy governs advertising. Vague, aspirational or unverified environmental messaging that may once have passed without scrutiny now carries concrete legal risk, from AGCM fines and court injunctions to competitor lawsuits and consumer class actions. The May 2026 court ruling demonstrates that enforcement is not a future prospect but a present reality. Brands and agencies that invest now in substantiation infrastructure, internal compliance workflows and pre-approved claim templates will protect themselves against liability while continuing to communicate genuine environmental achievements credibly. Those that delay risk costly remediation, forced campaign withdrawals and lasting reputational harm.
