How to Avoid Greenwashing: A Practical Guide for Businesses
How to Avoid Greenwashing: A Practical Guide for Businesses
Last updated: 24 June 2026 | Author: VerdaScope Editorial Team
How to avoid greenwashing is now a core compliance question for UK marketing, product, and sustainability teams—not a niche ethics debate. Regulators expect responsible green marketing: specific, evidenced claims aligned with the CMA Green Claims Code. Avoiding greenwashing reduces greenwashing risks for companies including CMA investigation, ASA rulings, contract loss, and rework of packaging and websites.
This how-to guide sets out a practical workflow for how companies can avoid greenwashing, including how to identify greenwashing and spot greenwashing in draft materials before publication. For definitions, see what is greenwashing. For legal detail, see UK Green Claims Code.
Status Summary (June 2026)
| Item | Detail |
|---|---|
| Core UK reference | CMA Green Claims Code (September 2021) |
| Enforcement trend | Active CMA sector work (e.g. fashion undertakings, March 2024) |
| Advertising layer | ASA/CAP Code |
| This guide | Operational prevention—not legal advice |
Direct Answer
To prevent greenwashing, UK businesses should: (1) inventory all environmental claims; (2) align each claim with the CMA’s six principles; (3) hold substantiation before publishing; (4) run cross-functional approval; (5) train commercial teams; and (6) review claims when products, data, or law change. How to spot greenwashing internally: test for vague terms, hidden trade-offs, missing caveats, and imagery that overstates reality.
Key Takeaways
- Prevent greenwashing with governance and evidence—not last-minute legal sign-off on finished creatives.
- Map every claim (including icons and filters) to substantiation files.
- Apply the same standards to B2B sheets, marketplaces, and retailer portals—not only consumer ads.
- Use the seven-sign checklist to identify greenwashing patterns early (types of greenwashing).
- Pair marketing controls with operational honesty—do not market progress you have not made.
- A structured sustainability audit can surface claim-and-data gaps before enforcement.
Before You Start: Scope and Roles
Who this process applies to
Any UK organisation—or overseas firm selling to UK consumers—that makes claims about environmental impact, including:
- Product and packaging claims
- Website, social, and paid advertising
- Sales and tender documents
- Investor and CSR pages (where they influence consumer or B2B product choices)
- E-commerce filters and category names
Roles to involve
| Role | Contribution |
|---|---|
| Sustainability / operations | Data, LCAs, targets, supplier evidence |
| Marketing / brand | Customer language, channel execution |
| Legal / compliance | CPRs, sector rules, approval logs |
| Product / procurement | Specifications, certificates |
| E-commerce | Filters, tags, marketplace copy |
| Leadership | Tone; avoid pressuring teams to overclaim |
Step 1: Audit Existing Claims
Outcome: A complete claim register.
- Export all live website copy mentioning environmental terms (eco, sustainable, recycled, carbon, net zero, etc.).
- Collect packaging, hangtags, and instruction leaflets.
- Review paid ads and social posts from the last 12 months.
- Include imagery (green leaves, planet icons) and range names (“Responsible,” “Conscious”).
- Capture retailer/distributor templates and marketplace listings.
- Log third-party logos and certification marks.
Register fields: claim text, channel, product SKU/scope, owner, evidence link, last review date, risk rating.
Step 2: Apply the CMA Six-Principle Test
For each claim, score against UK Green Claims Code principles:
| Principle | Pass question |
|---|---|
| Truthful and accurate | Is it factually correct and not exaggerated? |
| Clear and unambiguous | Would an average customer understand the meaning? |
| No material omissions | Are significant negatives disclosed? |
| Fair comparisons | Same methodology and like-for-like comparator? |
| Life cycle | Is the relevant life-cycle stage acknowledged? |
| Substantiated | Is evidence documented, current, and accessible? |
Fail any principle → narrow, qualify, or withdraw the claim.
Step 3: Build Substantiation Files
Outcome: One folder (physical or digital) per material claim.
Minimum contents:
- Claim wording and visual assets
- Evidence documents (lab tests, certificates, LCA summary, emissions inventory)
- Methodology and boundaries
- Date of evidence; next review date
- Named approvers (sustainability + legal/marketing)
- Customer-facing caveat text
Rule: No substantiation → no claim.

Step 4: Fix High-Risk Language
Replace vague terms
| High risk | Lower risk alternative |
|---|---|
| “Sustainable product” | “Contains 70% recycled steel; see recycling guide” |
| “Eco-friendly” | “Water-based coating; VOC content below [standard]” |
| “Green choice” | “50% lower Scope 1+2 emissions vs 2022 baseline at our UK plant” |
Add prominent caveats
If composting requires industrial facilities, say so next to the claim—not on a separate FAQ page in small type.
Correct imagery
Remove nature motifs unless tied to verified attributes. Align filters with SKU data.
Step 5: Implement Approval Workflow
Suggested gates
Draft claim → Sustainability review → Legal/compliance → Published → Scheduled reviewTriggers for re-approval:
- Supplier or formulation change
- New certification or loss of certification
- ASA/CMA case in your sector
- Expansion to EU markets (EU Green Claims Directive)
Agency and freelancer rules
Contractual clause: agencies must not invent environmental claims; use approved claim bank only.
Step 6: Train Commercial Teams
Sales and account managers are a common source of improvised “green” language.
Training topics:
- Approved claims and forbidden vague terms
- How to spot greenwashing in customer briefs demanding overstated copy
- Escalation contacts
- Documenting customer-specific claims in tenders
Step 7: Monitor and Review
KPIs for claim governance
Track metrics that predict regulatory and commercial exposure:
| KPI | Why it matters |
|---|---|
| % of live claims with current substantiation on file | Core compliance health |
| Average days since last claim review | Stale claims drift out of accuracy |
| Number of unapproved claims flagged in channel audits | Shows copy drift on marketplaces |
| Customer complaints citing “misleading green” language | Early warning signal |
| Time to remediate after evidence gap found | Reduces ASA/CMA exposure duration |
Report these quarterly to leadership—not only to marketing.
| Frequency | Activity |
|---|---|
| Quarterly | Spot-check top-traffic product pages |
| Annually | Full claim register review |
| Ad hoc | After complaints, reformulation, or enforcement news |
| Per campaign | Pre-flight checklist for new environmental campaigns |
Subscribe to CMA and ASA updates; read greenwashing in fashion if you sell textiles—even outside fashion, the undertakings illustrate regulator expectations.
How to Identify Greenwashing: Seven Signs Checklist
Use this quick scan on draft copy (also covers how to spot greenwashing for competitor benchmarking):
- Broad virtue words without metrics (sin of vagueness)
- Single-attribute highlight ignoring bigger impacts (hidden trade-off)
- Badges with no explanation (false labels)
- “Free from X” where X is already banned or irrelevant (irrelevance)
- “Greener” in an inherently high-impact category without context (lesser of two evils)
- Numbers that cannot be traced to a source (no proof / fibbing)
- Future tense sold as now (“net zero company” without current performance data)
Examples: Risky, Incomplete, and Compliant
| Status | Example | Issue / merit |
|---|---|---|
| Risky | “Planet-positive packaging” | Undefined; implies net environmental benefit |
| Incomplete | “Made with recycled materials” | Fails to state percentage or component |
| Compliant | “Tray: minimum 80% post-consumer recycled PET; lid not recycled—dispose as general waste” | Specific, scoped, disposal context |
RACI Matrix for Claim Governance
| Activity | Sustainability | Marketing | Legal | Procurement | Leadership |
|---|---|---|---|---|---|
| Claim register ownership | R/A | C | C | I | I |
| Evidence gathering | R/A | I | I | C | I |
| Customer-facing wording | C | R/A | C | I | I |
| Approval to publish | C | R | A | I | I |
| Supplier certificate audit | C | I | I | R/A | I |
| Post-incident response | C | R | A | C | A |
R = Responsible, A = Accountable, C = Consulted, I = Informed
Clear accountability prevents claims slipping through on “someone else’s desk.”
Escalation Protocol When Evidence Is Weak
Evidence gap identified
→ Can claim be narrowed to match evidence? → Yes → Revise and re-approve
→ No → Withdraw claim from all channels (web, pack, ads, B2B)
→ Notify distributors and marketplaces within defined SLA (e.g. 5 business days)
→ Log incident; root cause (supplier change, copy drift, new SKU)Speed matters: ASA complaints and social media screenshots preserve old claims indefinitely.
Integrating With Sustainability Reporting
If you publish SECR data, ESG reports, or net zero progress updates, ensure public marketing does not outpace regulated disclosures. Investors and customers cross-check. Align figures, boundaries, and dates across:
- Annual report and sustainability report
- Website hero claims
- Product-level carbon badges
- Sales enablement decks
See ESG reporting and net zero guide for reporting context.
Greenwashing Risks for Companies
| Risk | Mitigation in this guide |
|---|---|
| Regulatory investigation | Steps 2–5: principles test + substantiation + workflow |
| ASA complaint | Clear, qualified language; CAP alignment |
| Retailer delisting | Accurate B2B product data feeding portals |
| Greenhush (under-claiming from fear) | Document real progress with narrow, evidenced claims |
| EU export breach | Step 5 EU trigger + EU Green Claims Directive |
Common Mistakes
- Legal review without sustainability data
- Treating corporate slogans as low risk (they shape brand impression)
- Ignoring e-commerce filters
- Using offset purchases to justify “carbon neutral product” without reduction narrative (carbon offsetting)
- One-off campaign approval without updating master register
- Assuming SME size avoids scrutiny
Frequently Asked Questions
How to avoid greenwashing?
Audit claims, apply CMA principles, substantiate before publishing, approve cross-functionally, train staff, and review regularly.
How to identify greenwashing in our marketing?
Use the seven-sign checklist: vagueness, hidden trade-offs, false labels, irrelevance, category greenwashing, missing proof, and false numbers.
How to spot greenwashing in supplier claims?
Request certificates, test reports, and scope statements; do not repeat supplier copy without verification—you may be liable on packaging you sell.
How companies can avoid greenwashing without greenhushing?
Make specific, evidenced claims about real improvements—even modest ones—rather than broad silence or broad boasting.
What are greenwashing risks for companies?
Regulatory action, ad bans, consumer complaints, tender disqualification, brand damage, and cost of removing non-compliant materials.
Does this apply to B2B marketing?
Yes. BPRs cover misleading B2B advertising; CMA urges high standards. Procurement buyers increasingly audit claims.
When should we use a sustainability audit?
When entering new markets, launching eco-branded ranges, preparing for retailer questionnaires, or after acquiring brands with unknown claim history. See sustainability audit.

Board and Leadership Questions
Directors and founders should ask management:
- How many environmental claims are live across channels—and who owns the register?
- When did we last test product filters and marketplace copy against substantiation files?
- What would we produce within 48 hours if the CMA requested evidence for our top three claims?
- Are EU-facing claims reviewed separately from UK copy?
- Does our incentive structure reward sustainability outcomes or marketing volume?
Weak answers indicate greenwashing risks for companies that governance can fix before external enforcement.
Tooling Suggestions (No Endorsement)
Teams often use:
- Shared evidence repositories (SharePoint, Notion, DAM with metadata)
- Workflow tickets for claim approval (Jira, Asana)
- PIM/e-commerce systems tying SKUs to certified attributes
- Annual sustainability audit or legal compliance review
Tools do not replace judgement—but they reduce copy drift between channels.
Maturity Model: Where Is Your Organisation?
| Level | Characteristics | Priority action |
|---|---|---|
| 1 — Ad hoc | No claim register; teams improvise copy | Step 1 audit immediately |
| 2 — Reactive | Legal reviews some campaigns; no imagery policy | Build register + six-principle test |
| 3 — Defined | Register, approvals, training | Automate marketplace checks |
| 4 — Managed | KPIs, scheduled reviews, EU/UK split | External audit or certification where material |
| 5 — Optimising | Claims tied to live operational data feeds | Benchmark sector ASA/CMA cases quarterly |
Most UK SMEs reach Level 3 within one reporting cycle if sustainability and marketing share ownership. Level 4 is appropriate before any major “eco” rebrand or retailer listing that triggers enhanced due diligence.
