Greenwashing Audit Checklist for Marketing Teams 2026

A greenwashing audit checklist for marketing teams needs to cover every channel where environmental claims appear — not just the homepage. This checklist gives you 47 specific checkpoints organised by channel, aligned to the EU Green Claims Directive (ECGT) and equivalent national laws, and formatted for use in a quarterly compliance review or a pre-campaign launch audit.

Before starting the manual audit: run a GreenClaims Scanner on your website to automatically surface all environmental claims and risk-score them. This eliminates the most time-consuming part of the audit and lets you focus the manual review on edge cases and offline channels.

How to Use This Checklist

For each checkpoint, mark:

• ✅ Pass — compliant, documented
• ⚠️ Flag — needs attention within 30 days
• 🚫 Fail — non-compliant, must fix before enforcement contact
• N/A — not applicable to your business

Any single 🚫 Fail in categories 1–3 represents immediate regulatory exposure and should be escalated to legal counsel alongside remediation.

Category 1: Website — Product and Service Pages

1. No standalone vague environmental claims ("eco-friendly", "green", "sustainable", "responsible") used on any product or service page without qualification
2. All "recycled content" claims specify: percentage, type (pre/post-consumer), material, and certification reference
3. All "carbon neutral" or "climate neutral" claims have been removed or replaced with scoped, substantiated language (these terms are banned under ECGT as standalone claims)
4. All biodegradable or compostable claims specify: conditions required (industrial/home/marine), standard met, and test certification
5. No comparative environmental claims ("50% greener", "lower emissions than competitors") without a named comparison basis, same scope, and the same methodology applied to both
6. All sustainability badges or icons on product pages reference a named, accredited third-party certification (no self-awarded badges)
7. All certification badges displayed are current — not expired
8. Environmental claims about specific products are scoped to those products — no claim implies a company-wide or product-range-wide benefit that only applies to one line

Category 2: Website — Brand and Company-Level Pages

9. Homepage headline or tagline does not use standalone green adjectives without qualification ("We're a sustainable company")
10. "About" or "Our story" page environmental claims are accurate, scoped, and linked to evidence
11. "Sustainability" or "ESG" page: all quantitative claims (emission reductions, renewable energy percentages) link to the source report or certification
12. Sustainability report or page is independently assured — assurance provider named and assurance scope stated
13. No future environmental commitments are presented in a way that implies they are already achieved ("We're net zero" vs "Committed to net zero by 2040 — see our SBTi-validated plan")
14. Supply chain claims specify which portion of the supply chain they cover and cite supplier certifications

Category 3: Website — Navigation and UX

15. No product category filters using vague sustainability terms ("Eco-Friendly Collection", "Green Products") without an underlying, defined certification standard
16. Search results pages do not surface products under a sustainability filter unless those products are individually certified or attribute-verified
17. Pop-up or banner environmental messaging is subject to the same standards as static page content

Category 4: Paid Advertising

18. Google Ads headlines and descriptions do not use banned vague terms as standalone claims
19. All ad copy environmental claims are substantiated by the same evidence required for on-page claims — advertising standards bodies apply the same rules
20. Ad extensions (sitelink, callout) do not introduce environmental claims not substantiated on the linked landing page
21. Meta/Instagram/Facebook ad copy reviewed for standalone green claims
22. LinkedIn ad copy for B2B campaigns reviewed — B2B claims are also within ECGT scope
23. Programmatic/display banner environmental claims reviewed and documented
24. Paid search campaign targeting "eco", "sustainable", "green" keywords does not land on pages making non-compliant claims

Category 5: Email Marketing

25. Email subject lines do not use standalone vague environmental claims
26. Email body copy environmental claims meet the same substantiation standard as website copy
27. "Sustainable" or "eco" collection promotional emails link to substantiation or certification information
28. Email footer environmental claims (e.g., "this email is carbon neutral") are substantiated — if not, remove
29. Transactional email copy (order confirmation, delivery notifications) reviewed for incidental environmental claims

Category 6: Social Media

30. Social media bio / profile description does not use standalone green claims
31. Pinned or highlighted posts with environmental claims are accurate and current
32. Historical posts making environmental claims that are no longer accurate have been updated or removed (regulators can review historical content)
33. Social ad copy reviewed (covered in Category 4 but bears repetition for organic posts too)
34. Influencer content mentioning your products' environmental attributes: FTC and ASA rules require influencers to ensure sponsored claims are accurate — your brief to influencers should include ECGT-compliant claim guidance

Category 7: Packaging and Physical Materials

35. Product packaging environmental claims meet ECGT standards (same rules as digital)
36. Recycling instructions on packaging are accurate for the actual recyclability of the package in target markets — see our sustainable packaging guide
37. No recycling triangle symbol on non-recyclable packaging
38. Packaging claims do not use banned terms ("eco-friendly packaging", "sustainable packaging" without qualification)
39. Trade show and event materials reviewed — physical banners, brochures, and booth graphics are within ECGT scope

Category 8: Documentation and Governance

40. A substantiation file exists for every active environmental claim — contains evidence, scope, methodology, verification status, and review date
41. Substantiation files are current — evidence has been reviewed within the past 12 months or since the last product change (whichever is more recent)
42. A claims approval process exists requiring sign-off before new environmental claims are published
43. Copywriter and agency briefing documents include ECGT-compliant claim guidelines
44. A list of approved certifications and badges is maintained and communicated to all content creators
45. A process exists to review claims when product formulation, packaging, or supply chain changes
46. Legal counsel has reviewed environmental marketing claims within the past 12 months
47. Continuous automated monitoring is in place — GreenClaims Scanner or equivalent — to catch new violations as content is published

Audit Scoring and Next Steps

Fail Count	Risk Level	Recommended Action
0 Fails	Low	Maintain quarterly review cycle; implement continuous automated monitoring
1–3 Fails	Medium	Remediate fails within 30 days; review substantiation files for all flagged areas
4–10 Fails	High	Immediate remediation plan; involve legal counsel; pause any active campaigns with failing claims
10+ Fails	Critical	Immediate pause on all environmental claims pending legal review and full substantiation audit

Ongoing Compliance: Beyond the Quarterly Audit

This checklist is most powerful as part of a system rather than a one-off exercise. After completing the audit:

• Set up GreenClaims Scanner for daily automated monitoring — it will alert you when new content triggers a violation, between manual audits
• Schedule the next full audit in 90 days — or immediately after any major campaign launch or product change
• See GreenClaims Scanner pricing for team plans that include multiple domain monitoring and API access for pre-publish checks
