The Era of Unsubstantiated Green Marketing Is Over
For years, terms like “eco-friendly,” “green,” and “carbon neutral” have functioned as useful shortcuts in corporate communications. They signal environmental intent without requiring much specificity.
That era is ending.
The Empowering Consumers for the Green Transition (ECGT) Directive — formally Directive (EU) 2024/825 — was published in the Official Journal of the European Union on 6 March 2024. It amends two foundational pieces of EU consumer protection law: the Unfair Commercial Practices Directive (2005/29/EC) and the Consumer Rights Directive (2011/83/EU). EU Member States must transpose the Directive into national law by 27 March 2026, with enforcement beginning 27 September 2026.
The message from the European Parliament and Council is direct: if you cannot substantiate an environmental claim with recognized evidence, you should not be making it.
What the Directive Specifically Prohibits
The ECGT Directive does not introduce a vague aspiration toward better marketing. It identifies specific categories of claims that are now classified as unfair commercial practices. Understanding these categories is the first step in any compliance review.
Generic environmental claims without substantiation. Terms such as “eco-friendly,” “green,” “ecological,” reduced environmental impact, or “climate friendly” are prohibited unless the company can demonstrate recognized excellent environmental performance relevant to the claim. The burden is on the company to substantiate –not on the consumer to verify.
Whole-product claims based on partial attributes. Making an environmental claim about an entire product when it concerns only one component or aspect (for example, labelling a garment “sustainable” based solely on its fabric content, while ignoring manufacturing and logistics) is now explicitly restricted.
Claims based on greenhouse gas emission offsets. This is one of the Directive’s most consequential provisions. Claims suggesting that a product or organization has a neutral, reduced, or positive impact on the environment “in terms of greenhouse gas emissions” based on the purchase of carbon offsets are banned outright. This directly affects the widespread “carbon neutral” certification model.
Unregulated sustainability labels. Displaying a sustainability label that is not based on an official certification scheme (established under EU or Member State law) or by a public authority is prohibited. The Directive effectively targets the proliferation of self-created or commercially operated “green badges” that lack transparent, publicly accessible certification criteria, and independent oversight.
Unsubstantiated future performance claims. Environmental claims about future performance such as net-zero commitments are permitted only where they are supported by clear, objective, publicly available, and verifiable commitments. These must include measurable and time-bound targets, and an independent monitoring system.
The Green Claims Directive: Withdrawn, but the Principles Remain
The ECGT sets the prohibitions, but a companion proposal the European Commission’s Green Claims Directive (COM/2023/166 final, published March 2023) was designed to establish the methodology for substantiation. It would have required companies to base explicit environmental claims on widely recognised scientific evidence, use a life cycle approach, and have claims verified by an accredited independent body before publication.
In June 2025, the Commission announced its intention to withdraw the Green Claims Directive proposal, citing concerns about administrative burden on micro-enterprises. Trilogue negotiations(informal, tripartite meetings between the European Parliament, the Council of the European Union, and the European Commission) were suspended.
This does not reduce the compliance obligation. The ECGT remains fully in force and independently enforceable. Companies that were waiting for the Green Claims Directive to clarify substantiation standards should not interpret its withdrawal as a relaxation of the rules; the prohibitions on generic claims, offset-based claims, and unregulated labels apply regardless.
Compliance Timeline at a Glance
- 6 March 2024: ECGT Directive published in the Official Journal of the EU
- 27 March 2026: Deadline for Member States to transpose into national law
- 27 September 2026: National rules begin to apply — enforcement starts
- Green Claims Directive: Commission announced intention to withdraw in June 2025; trilogue negotiations suspended
Companies making environmental claims in EU markets or marketing to EU consumers should treat the September 2026 application date as a hard planning milestone, regardless of where their headquarters are located.
What This Means in Practice
For sustainability, communications, and legal teams, the ECGT requires a systematic review of all externally facing environmental claims. This includes marketing materials, product packaging, website copy, investor communications, and sustainability reports.
The practical steps are clear. Audit every environmental claim currently in use across all channels. Identify which claims are generic and which are specific and substantiated. For each claim, document the evidence base, the scope (whole product or partial), and the source of any certification. Remove or replace any claims that rely solely on purchased carbon offsets. Ensure that forward-looking commitments meet the Directive’s standards for measurable targets and independent monitoring. Do not assume that the Green Claims Directive’s withdrawal has lowered the bar, the ECGT’s prohibitions are independently enforceable.
Accurate Claims Serve a Larger Purpose
Precise, evidence-based environmental communication is not just a legal obligation, it is the mechanism through which markets, investors, and consumers can distinguish genuine environmental progress from noise. At a time when public trust in corporate sustainability messaging is under pressure, the ECGT represents an opportunity to raise the quality and credibility of the conversation.
Better claims lead to better decisions. And better decisions are what the transition ultimately requires.
