A reef campaign is an easy thing to get wrong. The subject is emotive, the imagery is beautiful, and the pressure to sound impressive — from funders, sponsors and your own posting schedule — is constant. That combination produces claims that outrun the evidence, and claims that outrun the evidence are exactly what regulators, journalists and sceptical members of the public now look for.
Greenwashing is not only lying. Most complaints that reach the advertising regulator and the competition authority concern vagueness, missing context and images that imply more than the facts support. The checklist below is meant to be worked through before a campaign, a product label or a partnership goes live — not after a complaint lands on your desk.
What regulators actually object to
Four patterns do most of the damage. First, the undefined word: "eco-friendly", "ocean-positive", "reef-safe". Second, the hidden trade-off: promoting a refillable bottle while saying nothing about how far it was shipped. Third, the borrowed image: a tropical reef on packaging for something made and sold in Britain. Fourth, the unqualified absolute: "the most sustainable sunscreen on the market", with no comparison you could stand behind.
The test is the overall impression, not the individual sentence. A statement that is literally true can still mislead if the surrounding text or picture steers the reader somewhere the evidence does not go. Regulators read the whole thing — caption, logo, hashtag and all.
The UK legal baseline
Two bodies of law matter most. Consumer protection law — the Consumer Protection from Unfair Trading Regulations 2008 for business-to-consumer dealings, and the Business Protection from Misleading Marketing Regulations 2008 for business-to-business — prohibits misleading actions and omissions. Advertising rules sit alongside them. The CAP Code covers ads, which includes paid social posts, influencer content and sponsored placements, and the Advertising Standards Authority can require a claim to be changed or withdrawn.
The Competition and Markets Authority's Green Claims Code sets out six principles that any environmental claim should meet:
- Claims must be truthful and accurate.
- Claims must be clear and unambiguous.
- Claims must not omit or hide important relevant information.
- Comparisons must be fair and meaningful.
- Claims must consider the full life cycle of the product or service.
- Claims must be substantiated.
The Digital Markets, Competition and Consumers Act 2024 strengthens the CMA's hand: once the relevant provisions are in force, the authority can act directly against infringements without going to court and can impose penalties. Environmental claims are among the practices in scope. Separately, the Financial Conduct Authority has introduced an anti-greenwashing rule for regulated financial promotions, so if your campaign involves investments or financial products, a different regime may bite.
This is a summary, not legal advice. For anything high-profile — a national campaign, a product label, a carbon claim — take a solicitor's view before publication rather than after.
A pre-publication checklist
- Scope. Does the claim apply to one product, one project, one campaign or the whole organisation? Write the boundary down and check the wording matches it.
- Evidence, now. Can you produce the supporting data today? Note who holds it, how it was gathered and how old it is.
- Plain meaning. Read the claim as a stranger would. What do they think you have promised?
- Omissions. What has been left out — a baseline year, a geographical boundary, a failure rate, a caveat about method?
- Comparisons. Is it genuinely like-for-like? Different products, baselines and survey methods are not comparable.
- Substantiation trail. Keep the file: methodology, monitoring reports, supplier evidence, approvals, names and dates.
- Accountability. Every environmental claim should have a named owner who can defend it.
Reef-specific traps
"Reef-safe", "reef-positive" and similar terms
These phrases have no legal definition in the UK. If you use one, define it in the same place the reader sees it — an ingredient list, a testing standard, a published methodology. If no definition exists, the honest option is not to use the term at all.
Carbon and offsetting claims
Say what is counted, what is excluded, and whether you reduced emissions before buying offsets. "Carbon neutral" as a bare badge invites scrutiny, and marine offsetting is a contested field with varying verification standards. Treat it as a claim that needs a methodology attached, not a logo.
Imagery and geography
Do not use tropical reef footage for a cold-water project in Scottish waters, and do not use another organisation's restoration site in your own material without written permission. Pictures carry claims as surely as words do.
Restoration numbers
"Planted 10,000 fragments" says nothing about survival. Prefer: "we planted 10,000 fragments at [site]; twelve-month monitoring found X per cent survival using [method]". Naming the method and the monitoring period makes the number defensible.
Donations and partnerships
"A percentage of profits supports reef restoration" needs a defined amount, a named recipient and a timeframe. Get written permission before using a charity's name or logo, and be clear whether the contribution is a fixed sum, a match or a percentage.
Legal is not the same as honest
Some claims pass every test and still erode trust. Watch for these:
- Presenting offsetting as a substitute for cutting your own footprint.
- Calling a habitat "recovered" after a single short monitoring season.
- Using volunteers or coastal communities as backdrop without naming them or sharing results with them.
- Describing contested science as settled, in either direction.
- Allowing a sponsor to influence findings, or appearing to.
- Using urgency to shut down fair questions from local people, fishers or journalists.
When advocacy goes too far
Campaigners face their own exposure. Calling a company a "reef destroyer", or asserting that a development is unlawful, without a sound factual basis can lead to complaints about your own advertising and, in serious cases, to defamation or malicious falsehood claims. Stick to what you can evidence: the permit, the environmental statement, the monitoring report, the date of the breach. Where you are characterising rather than stating a fact, make the basis of your opinion clear, and keep your source material.
Making it routine
Build a simple claims register listing every environmental statement you make, where it appears, who signed it off, what evidence supports it and when it should
