The EU ECGT Directive (2024/825) bans or restricts 28 environmental marketing terms when used without proper substantiation. Here is the complete list, organized by risk level.
What Makes a Green Claim "Banned"?
Under Article 3(1)(b) of the ECGT Directive, generic environmental claims are prohibited unless the trader can demonstrate recognized excellent environmental performance relevant to the claim. This means terms like "eco-friendly" or "green" cannot be used in marketing unless backed by certified evidence.
Critical Risk Terms (Banned Without Certification)
These terms are essentially banned from marketing materials unless the product/service holds a recognized EU Ecolabel or equivalent certification.
| Term | Why It's Banned | ECGT Reference | Compliant Alternative |
|---|---|---|---|
| Eco-friendly | Generic claim, no measurable criteria | Art. 3(1)(b) | "EU Ecolabel certified" (with certificate number) |
| Environmentally friendly | Same as eco-friendly, equally vague | Art. 3(1)(b) | Specific impact metric (e.g., "30% less water usage vs. 2020 baseline") |
| Carbon neutral | Usually relies on offsets, which ECGT restricts | Art. 3(4) | "X tonnes CO2 reduced in our operations (independently verified by [auditor])" |
| Climate neutral | Same issues as carbon neutral | Art. 3(4) | Verified emission reduction with methodology reference |
| Carbon negative | Relies on offset claims | Art. 3(4) | Verified scope 1-3 reductions with third-party audit |
| Net zero | Requires SBTi-validated pathway, not just offsets | Art. 3(4) | "On track to SBTi-validated net zero by [year]" |
| Green | Meaningless without context | Art. 3(1)(b) | Specific environmental benefit with evidence |
| Clean | Implies zero pollution, rarely verifiable | Art. 3(1)(b) | "Meets [specific standard] emission limits" |
High Risk Terms (Restricted Without Evidence)
These terms require specific substantiation — typically third-party certification, lifecycle assessment, or verifiable data.
| Term | Required Substantiation | ECGT Reference |
|---|---|---|
| Sustainable | Full lifecycle assessment (LCA) covering all relevant environmental aspects | Art. 3(1)(b) |
| Biodegradable | Timeframe, conditions (industrial vs home composting), certification (EN 13432) | Art. 3(1)(a) |
| Compostable | EN 13432 or equivalent certification, specify conditions | Art. 3(1)(a) |
| Recyclable | Actual recycling infrastructure availability, not just theoretical recyclability | Art. 3(1)(a) |
| Natural | Define what percentage is naturally sourced, avoid implying "chemical-free" | Art. 3(1)(b) |
| Non-toxic | Toxicological data, REACH compliance proof | Art. 3(1)(a) |
| Organic | Official organic certification (EU Organic, USDA, etc.) | Art. 3(1)(b) |
| Renewable energy | Guarantee of Origin (GO) certificates, actual procurement (not just RECs) | Art. 3(1)(a) |
| Ethical | Specify which ethical standards (labor, sourcing, etc.) | Art. 3(1)(b) |
| Responsible | Define responsibility criteria and verification method | Art. 3(1)(b) |
Medium Risk Terms (Use With Caution)
These terms are not outright banned but must be used carefully with supporting evidence to avoid being classified as misleading.
| Term | How to Use Safely |
|---|---|
| Energy efficient | Reference EU Energy Label class or specific consumption reduction percentage |
| Low carbon | Quantify: "X% lower carbon footprint than industry average (verified by [method])" |
| Reduced emissions | Specify baseline, reduction percentage, scope, and verification |
| Plant-based | Specify percentage of plant-derived ingredients |
| Zero waste | Define scope and include diversion rate data |
| Eco-conscious | Vague — better to use specific environmental metrics |
| Circular | Explain the specific circular economy practice (take-back program, refurbishment, etc.) |
| Climate positive | Must demonstrate net removal beyond value chain emissions |
| Sustainably sourced | Specify certification (FSC, MSC, Rainforest Alliance, etc.) |
| Carbon offset | ECGT restricts offset-based claims — must disclose methodology and registry |

Frequently Asked Questions
Which environmental terms are banned under EU law?
The ECGT Directive (2024/825) restricts 28 terms across three risk tiers. Banned without certification: eco-friendly, environmentally friendly, carbon neutral, climate neutral, carbon negative, net zero, green, and clean. Restricted without evidence: sustainable, biodegradable, compostable, recyclable, natural, non-toxic, organic, and renewable energy. All restrictions apply in EU member states from September 27, 2026.
When do the EU green term restrictions take effect?
September 27, 2026 — now 45 days away. EU member states must transpose the ECGT Directive (2024/825) into national law by that date. From then, using prohibited terms like “eco-friendly” or “carbon neutral” without certification exposes businesses to fines of up to 4% of annual EU turnover.
Can I still say my product is sustainable after September 2026?
Only with a full lifecycle assessment (LCA). Under ECGT Article 3(1)(b), “sustainable” requires substantiation covering all relevant environmental aspects of the product or service. A general sustainability claim without specific evidence and scope definition is prohibited. Compliant alternative: cite the specific metric (e.g., “30% lower lifecycle CO2 vs. 2020 baseline, verified by [named auditor]”).
What is the penalty for using banned green terms in the EU?
Financial penalties of up to 4% of annual EU turnover, determined by each member state’s national authority. Businesses may also be excluded from public procurement for up to 12 months. Enforcement is handled by national consumer protection authorities: DGCCRF in France, Wettbewerbszentrale in Germany, ACM in the Netherlands. These agencies already use AI tools to screen corporate websites for prohibited terms at scale.
Does the ECGT green terms ban apply to non-EU companies?
Yes. Any business marketing goods or services to EU consumers must comply, regardless of where the company is based. A US, UK, or Asian brand running advertising that targets European customers falls under ECGT jurisdiction. The trigger is directing commercial communications to EU consumers — not the physical location of the business.
