Three in four UK consumers say they are trying to play their part on sustainability, and they expect brands to do the same. That figure comes from a BCG survey of 10,000 UK consumers across 13 sectors, and it points to a shift that is hard to overstate for business owners. The question is no longer whether sustainability matters to your customers, but whether your business is responding in a way they actually notice and trust.

The gap between the 76% who care and the 8% who will pay more is where the real commercial picture sits. Most consumers expect sustainability to come as standard, not as a premium add-on. What they do with that expectation — switch, advocate, or walk away — depends on whether they trust what you are saying. Here’s what you actually need to know.
One term worth knowing is greenhushing. It describes the growing tendency among businesses to stay quiet about genuine sustainability work to avoid being accused of greenwashing. The Brand Finance research on UK consumer attitudes identifies this as an emerging risk: consumers want to hear what you are doing, but only if the claims are specific and backed up.
What I tend to notice is that the businesses caught in the middle — neither shouting nor staying silent — are the ones that have a clear handle on their actual data. Without that, every claim feels risky.
What Changes When Sustainability Is Ignored or Mishandled
The commercial consequences of getting sustainability wrong are not hypothetical. A climate risk assessment from IGD projects that climate change could add £2.6 billion to UK food system costs by 2050 under a business-as-usual scenario. That is a direct cost pressure on supply chains, raw materials, and logistics — before you factor in consumer behaviour.
On the consumer side, the numbers are sharper. Among the 30% of consumers who take action based on sustainability perceptions, roughly half become vocal promoters or critics. A single negative experience or a perceived misleading claim can trigger advocacy against your brand that reaches far beyond the individual customer. The BCG data shows that 25% of consumers become vocal promoters who drive purchasing shifts in their social circles.
Regulatory exposure adds another layer. The Green Claims Code gives the Competition and Markets Authority power to impose significant financial penalties for misleading environmental claims. Extended Producer Responsibility for packaging and textiles shifts waste costs back onto producers. These are not future possibilities — they are active enforcement regimes.
Where Businesses Commonly Get This Wrong
Treating sustainability as a marketing campaign rather than an operational shift
The most expensive mistake is leading with a sustainability message before the operations support it. Consumers are increasingly good at spotting the gap between a brand’s claims and its actual practices. The BCG research found that less than half of consumers feel well informed about what brands are doing on sustainability, which creates a trust vacuum. If your marketing says one thing and your supply chain says another, the market will find out. Friends and family are the most trusted source of information on sustainability, and digital channels rank second — meaning word spreads fast.
Greenhushing — staying quiet out of fear
Some businesses with genuine sustainability work choose to under-communicate it to avoid greenwashing accusations. The Brand Finance research flags this as a real trend. The problem is that consumers cannot reward what they do not know about. If your products use recycled materials, certified supply chains, or lower-carbon processes and you do not say so, you hand the advantage to competitors who are more willing to talk — even if their actual impact is smaller. The fix is not to shout louder, but to make claims that are specific, measurable, and verifiable.
Ignoring the generational divide
Many businesses treat all consumers as equally concerned about sustainability. The data shows otherwise. Gen Z is not just more aware — they are five times more likely to act negatively than older consumers. A brand that loses credibility with this group does not just lose a single sale; it loses future lifetime value and referral potential. Meanwhile, older consumers are less likely to punish or reward based on sustainability, so the net effect of ignoring Gen Z is a slow erosion of your younger customer base.
Overlooking the regulatory timeline
The Extended Producer Responsibility for packaging is already phasing in, and the UK Sustainability Reporting Standards are raising expectations for decision-useful environmental data. Businesses that treat compliance as a future problem rather than a current one risk penalties and last-minute scrambling. The IGD trends report makes clear that policy and regulation are moving from ambition to delivery within the next nine months.
What I would flag as the most costly of these is the first one — marketing without operational substance. It is the hardest to walk back and the most likely to trigger both consumer backlash and regulatory action.
| Approach | Consumer response | Regulatory risk |
|---|---|---|
| Greenwashing — exaggerated or vague eco-claims | Distrust, negative advocacy, brand switching | High — Green Claims Code penalties |
| Greenhushing — under-communicating real achievements | Low awareness, missed opportunity, lost switching | Low — but commercial disadvantage |
| Authentic communication — specific, verified claims | Trust, positive advocacy, measured switching | Low — compliant by design |
Building a Sustainability Strategy That Actually Works
Get the data right before you say anything
Every sustainability claim needs a foundation of reliable data. The IGD research emphasises that a key UK challenge is effectively using sustainability data — it is often not shared within or between organisations and not embedded into commercial decision-making. Start with what you can measure: energy use, material sourcing, waste volumes, transport emissions. The UK Sustainability Reporting Standards (UK SRS S1 and S2) provide a framework for what decision-useful reporting looks like. If you cannot back up a claim with numbers, do not make it.
Match your message to your audience
The BCG research shows that friends and family are the most trusted source of sustainability information, followed by digital channels. For consumers under 45, social media is the primary reference point. For older consumers, websites carry more weight. That means a single message across all channels will miss parts of your audience. Tailor the depth and format of your sustainability communication to where each group looks for information. Simple, compelling messages work for high-speed purchase decisions; more detail matters for considered purchases.
Prepare for the regulatory baseline
Extended Producer Responsibility for packaging and textiles shifts end-of-life costs onto producers. The Green Claims Code is actively enforcing against misleading claims. The UK SRS is raising the bar for reporting. These are not optional frameworks — they are becoming the operating standard. A practical first step is auditing your current product claims and supply chain data against the Green Claims Code criteria. If you use terms like “eco-friendly” or “sustainable” without specific backing, those are the claims most likely to attract scrutiny.
Watch the emerging compliance timeline
The IGD trends report identifies several developments within the next nine months that will affect UK businesses: the farming roadmap informed by the Baroness Batters profitability review, the UK Methane Action Plan, and the potential inclusion of anaerobic digestion in the Circular Economy Strategy. For fashion and textile businesses, the SourceReady market report notes that EPR for textiles is phased by 2026, with brands paying fees based on textile waste volume. These timelines mean that waiting until a regulation is fully in force before acting is too late — the data collection and reporting systems need to be in place beforehand.

The Regulatory Window Is Closing Faster Than Most Businesses Expect
The IGD trends report is clear: sustainability in the UK food and grocery sector is an immediate commercial and operational challenge, not a long-term ambition. That applies across retail, fashion, and consumer goods. The combination of consumer expectations — where 57% of consumers are already influenced by sustainability practices — and regulatory enforcement means the businesses that treat sustainability as a compliance issue rather than a strategic one will be reacting to penalties rather than capturing advantage. The UK sustainable fashion market alone is projected to grow from USD 260 million in 2025 to over USD 2.5 billion by 2035, a 23.10% compound annual growth rate that signals where consumer spending is heading.
