A sustainability claim that outruns the supply chain
A fashion retailer plans a "100% sustainable cotton" campaign across paid social, influencer content and in-store POS. Its supply chain team confirms that 64% of cotton is certified (GOTS or equivalent) and 36% is conventional, sourced through a trader who cannot currently trace it to farm level. The campaign is scheduled for eight weeks, with £220,000 media spend and 14 influencers briefed to use the phrase. The legal team has flagged the claim as potentially misleading under consumer protection rules. The sustainability director argues that "everyone in the sector phrases it loosely" and that pulling the campaign would hand momentum to competitors. A customer panel shows 71% of shoppers interpret "100% sustainable" as meaning the entire product is sustainable, including dyeing and labour.
1. Advise the marketing director on the claim. What is the risk and what wording could be defended?
Read the worked answer
The claim as drafted is not defensible. "100% sustainable cotton" is an absolute claim, and 36% of the cotton is conventional and untraceable. The legal team's flag is well founded: consumer protection rules require claims to be truthful, clear and substantiated, and absolute claims cannot be qualified away in small print.
The customer-panel finding makes it worse. 71% of shoppers read the phrase as covering the whole product, including dyeing and labour - a meaning the retailer cannot substantiate. That is a misleading-impression risk, not a technicality, and it is amplified by 14 influencers repeating the phrase to large audiences.
Defensible alternatives:
- "Made with 64% certified cotton" - specific, verifiable and honest about the gap.
- "Working towards 100% certified cotton by [year]" - a credible target with a published roadmap, provided the roadmap exists and is funded.
- Product-specific claims where certification is complete, rather than a blanket brand claim.
Conditions I would attach:
- Brief influencers on exact approved wording, with no paraphrasing into absolutes. Their reach multiplies any error.
- Substantiation file held before launch: certificates, supplier declarations, audit trail.
- Traceability plan for the 36%, with milestones, since the claim will be scrutinised.
- Pull or reword POS and paid social - the two hardest to correct once live.
"Everyone phrases it loosely" is not a defence; enforcement increasingly targets exactly this kind of absolute claim.
2. The sustainability director warns of lost momentum. How would you weigh commercial urgency against claim integrity?
Read the worked answer
This is a risk-adjusted value decision, not a binary choice between launching and cancelling.
Downside of launching as drafted:
- Regulatory action and forced withdrawal mid-campaign, wasting part of £220,000.
- Influencer amplification makes correction slow and public.
- Loss of trust is asymmetric: a misleading green claim damages the brand far more than a delayed campaign.
- Retail partners may distance themselves.
Downside of pausing:
- Eight weeks of momentum and some media spend committed.
- Competitor visibility in the short term.
Weighing them, the expected cost of a misleading claim exceeds the cost of a two-to-three-week delay. A reworded campaign retains most of the momentum, because the creative, media buying and influencers can still run - only the wording changes. The delay is not eight weeks; it is the time to re-brief and re-approve copy.
My recommendation:
- Do not cancel - reword and launch on a slightly compressed schedule.
- Ring-fence the traceability work as a funded programme, so the "working towards" claim becomes true.
- Set a review gate at week four: if certification coverage has not risen, the forward-looking claim is paused.
- Report the decision to the board with the legal advice attached, so accountability is clear.
The sustainability director's concern is legitimate but misdirected: the risk to momentum comes from an indefensible claim being challenged publicly, not from taking three weeks to make it accurate.
