Environmental Marketing Compliance Checklist: 27 Points to Audit Before September 2026

After helping several companies prepare for ECGT compliance, I noticed they all made the same initial mistake: they focused exclusively on product packaging. Meanwhile, their website sustainability pages, social media accounts, and investor presentations were packed with unsubstantiated environmental claims nobody had reviewed.

This checklist covers every communication channel where environmental claims might appear. Print it, share it with your marketing and legal teams, and work through it systematically. Each item maps to a specific requirement in Directive 2024/825/EU or the forthcoming Green Claims Directive.

Section 1: Website and Digital Content (10 Points)

1. Homepage Environmental Statements

Does your homepage contain environmental claims? Check taglines, hero sections, and value propositions. "Building a sustainable future" as a company tagline is a generic environmental claim under the ECGT and requires substantiation or removal.

2. Sustainability Page Audit

Review every statement on your sustainability or CSR page. Each claim must have corresponding evidence. "We're committed to net zero by 2030" requires a published roadmap, interim targets, and a methodology disclosure. Aspirational language without a concrete plan is non-compliant.

3. Product Descriptions

Search your product catalogue for terms: eco, green, sustainable, natural, organic, biodegradable, recyclable, carbon neutral, climate friendly, environmentally friendly. Each instance needs review. Pay special attention to automated product descriptions generated by your CMS — these often contain template environmental language nobody approved.

4. Blog and Content Marketing

Old blog posts don't get a free pass. If a 2021 blog post claims your packaging is "100% sustainable" and it's still indexed, it's a compliance risk. Audit archived content, not just recent publications.

5. Meta Descriptions and Title Tags

SEO metadata counts as commercial communication. A meta description saying "Shop our eco-friendly collection" is a published environmental claim, even if consumers only see it in search results.

6. Image and Visual Claims

Green colour schemes, leaf icons, nature imagery, and earth symbols used alongside products without genuine environmental credentials can constitute misleading environmental claims. The ECGT explicitly covers visual communication, not just text.

7. Customer Testimonials

If you publish customer reviews that mention environmental attributes ("I love that this product is carbon neutral"), you're endorsing that claim by featuring it. Curated testimonials fall under your responsibility.

8. FAQ and Support Content

Knowledge base articles, FAQs, and chatbot responses often contain environmental claims written by support teams without marketing or legal review. Audit these channels.

9. Job Postings

"Join a company that's making a difference for the planet" in a job posting is an environmental claim used for commercial purposes (employer branding). These need the same scrutiny as customer-facing claims.

10. Cookie and Privacy Policy Language

Some companies reference their environmental commitment in privacy or cookie policies. It's less common, but check anyway — you'd be surprised.

Section 2: Packaging and Labelling (6 Points)

11. Front-of-Pack Claims

Every environmental statement on primary packaging must be substantiated. "100% recyclable" requires evidence that recycling infrastructure exists and is accessible to the consumer — not just that the material is technically recyclable.

12. Sustainability Labels and Seals

Verify every label and seal against the directive's certification requirements. Third-party certifications from recognised bodies (EU Ecolabel, FSC, GOTS) are compliant. Self-created labels or industry association labels without independent verification are not.

13. Material Claims

"Made from recycled materials" — what percentage? From what source? Post-consumer or post-industrial? Under the ECGT, recycled content claims must be specific and verifiable.

14. End-of-Life Claims

"Compostable" packaging must specify conditions: home compostable or industrial composting? What certification standard (EN 13432 for industrial, OK Compost Home for home)? Without specifics, the claim is misleading.

15. Comparative Claims on Packaging

"30% less plastic than our previous packaging" requires disclosure of the comparison methodology, the baseline product, and the measurement standard used.

16. QR Codes and Digital Extensions

If packaging links to a digital sustainability page via QR code, the content of that page is part of the product claim. Ensure linked content is also compliant.

Section 3: Advertising and Social Media (5 Points)

17. Paid Advertising Copy

Google Ads, Meta ads, LinkedIn campaigns — any paid media containing environmental claims is covered. Review ad copy across all platforms and all active campaigns.

18. Social Media Posts

Instagram captions, LinkedIn posts, tweets. "Proud to be a carbon neutral company" posted on Earth Day is an environmental claim. Social media content needs the same evidence base as any other commercial communication.

19. Influencer Partnerships

If influencers make environmental claims about your products, you share responsibility for substantiation. Influencer briefs must include approved environmental language and prohibited terms.

20. Video Content

YouTube videos, TikTok content, webinars. Spoken environmental claims in video are held to the same standard as written ones. This includes automated captions.

21. Email Marketing

Newsletter subject lines, promotional emails, transactional emails. "Your eco-friendly order is on its way" in a shipping confirmation is a commercial environmental claim.

Section 4: Corporate Communications (4 Points)

22. Annual and Sustainability Reports

Corporate sustainability reports distributed to stakeholders are commercial communications. Forward-looking statements ("We will achieve net zero by 2030") must be backed by published transition plans. For companies subject to CSRD, alignment between sustainability report claims and ECGT requirements is essential.

23. Investor Presentations

Environmental claims in investor decks, earnings calls, and shareholder communications carry legal weight under both the ECGT and securities regulations. Double exposure means double the compliance burden.

24. Press Releases

A press release claiming a "breakthrough in sustainable manufacturing" is a published environmental claim. Media relations teams need the same compliance training as marketing teams.

25. Industry Event Materials

Trade show booths, conference presentations, industry publications. "Leading sustainable innovation" on your exhibition banner is an environmental claim.

Section 5: Evidence Documentation (2 Points)

26. Evidence Register

For every claim that passes the audit as compliant, maintain an evidence register documenting: the claim, the evidence supporting it, the methodology used, the date of the evidence, and the responsible person. This register is what regulators will ask for during an investigation.

27. Review Schedule

Claims compliance is not a one-time exercise. Establish a quarterly review process for new marketing materials, updated product descriptions, and social media content. Assign a responsible person — ideally someone in legal or compliance, not marketing.

Using This Checklist

Work through each point with your marketing, legal, and sustainability teams. For each claim identified, assign one of three statuses:

Green — Compliant: Specific claim with documented evidence, third-party verification where required
Amber — Needs work: Claim may be defensible but evidence gaps exist or language needs tightening
Red — Non-compliant: Generic claim without substantiation, offset-dependent neutrality claim, or unverified label

Red items need immediate action: remove or reformulate before September 2026. Amber items need evidence gathering. Green items need documentation for your evidence register.
