Greenhushing: Why Going Quiet on Sustainability is Riskier Than Speaking Up

There’s a quiet shift happening in how businesses talk about sustainability. Faced with tighter regulation, high-profile greenwashing cases, and the growing risk of public backlash, a growing number of companies have landed on the same strategy: say nothing.

The thinking goes: if you don’t make claims, you can’t be caught making the wrong ones. Keep your head down. Let the regulations settle. Wait and see.

It’s called greenhushing — and it’s now one of the most significant trends in corporate sustainability communications. South Pole’s research across 14 major sectors found that in most industries, the majority of companies with genuine sustainability credentials are now communicating less about them — in some sectors, as many as 88%. A third of businesses that are actively investing in sustainability are intentionally going quiet.

The problem is that silence isn’t the safe option it appears to be. It creates legal exposure, erodes commercial credibility, and hands an advantage to competitors who’ve worked out how to communicate without overclaiming. This article explains why greenhushing has taken hold, what it actually costs, and what businesses should be doing instead.

What Greenhushing Actually Means

Greenhushing is the deliberate under-communication of sustainability efforts. Not lying, not exaggerating — simply staying quiet about progress that is real and, in most cases, worth talking about.

It’s the direct behavioural response to the greenwashing crackdown. As regulators in the UK and EU have tightened the rules around environmental claims — and as high-profile enforcement cases have made headlines — businesses have concluded that the safest move is to avoid making claims at all. If you don’t say anything, no one can say you said the wrong thing.

This is understandable. Greenwashing regulation is genuinely complex, enforcement risk is rising, and the reputational cost of getting it wrong is high. The instinct to pull back is rational, at least on the surface.

But it’s built on a flawed premise: that the only risk in sustainability communications is saying too much. The evidence increasingly suggests that saying too little carries its own substantial costs — commercial, legal, and strategic.

How Widespread is it?

The scale is significant and growing. A GlobeScan report published in January 2026 found that in 2025, just 36% of consumers reported seeing sustainability messaging from brands — down from 49% in 2023. That 13-point drop in two years is not explained by reduced consumer interest. Consumer demand for sustainability transparency has, if anything, increased. The decline reflects deliberate corporate withdrawal from the topic.

The gap between what businesses are actually doing and what they’re communicating is striking. 87% of companies are maintaining or increasing their ESG investments. 83% of C-suite leaders report increasing sustainability spend year-on-year. Yet a third are communicating less about it than they were two years ago.

In the US, the trend has been accelerated by political pressure. ESG has become a target for anti-regulation campaigns, and some large businesses — including FTSE-equivalent companies — have quietly removed sustainability language from annual reports, websites, and marketing materials. The UK isn’t immune. The same fear of backlash, combined with regulatory complexity, is pushing British businesses in the same direction.

The Legal Risk Nobody is Talking About

The assumption underpinning greenhushing is that silence is legally neutral. It isn’t.

Under UK consumer protection law, a misleading commercial practice includes not just false statements but misleading omissions; cases where a business withholds material information that a consumer would need to make an informed purchasing decision. This is not a grey area. The CMA’s Green Claims Code, the Consumer Protection from Unfair Trading Regulations, and the Advertising Standards Authority’s guidance all make clear that hiding or suppressing relevant sustainability information can itself constitute a breach.

In practice, this creates a specific risk for businesses that have genuine sustainability credentials but are not communicating them. If a consumer or regulator can demonstrate that the omission of that information influenced a purchase decision, or created a misleading overall impression of a product or business, the silence itself becomes the problem.

There is also a procurement dimension. An increasing number of large buyers and institutional clients are requiring suppliers to provide sustainability evidence as part of tender and due diligence processes. A business that has been deliberately quiet about its credentials may find that the absence of documentation is treated as the absence of credentials, not as a neutral position.

The ‘Overall Impression’ Test

UK advertising and consumer law does not assess claims in isolation. The question regulators and courts ask is: what impression does the overall communication create in the mind of a reasonable consumer? A business that operates in a clearly sustainability-adjacent market — say, organic food, recycled packaging, or low-carbon services — but makes no claims at all may, in certain circumstances, be creating an impression by omission.

This isn’t to say that every business that goes quiet is automatically in breach. But the idea that silence is a zero-risk position misunderstands how the law works. The risk profile depends on your market, your customers, and what your competitors are saying around you.

The Commercial Cost of Going Quiet

Beyond the legal dimension, greenhushing has a straightforward commercial cost that is easy to underestimate.

UK consumers are not stepping back from sustainability. 69% of UK consumers say sustainability is a factor in their purchasing decisions. 73% say they prefer sustainable brands. 80% say they are willing to pay a premium for products that meet environmental criteria. This is not a niche sentiment — it reflects mainstream consumer expectations in 2026.

When businesses go quiet on sustainability, they are making an invisible case. Customers who care about sustainability, and there are a lot of them, are not receiving the information they need to choose you over a competitor. They may default to the business that is communicating, even if its actual sustainability credentials are weaker than yours.

GlobeScan’s January 2026 data makes the mechanism explicit: the decline in consumer engagement with sustainability is closely linked to reduced brand communication, not just external factors like economic pressure or climate fatigue. Trust in sustainability messaging has also dropped sharply; from 79% of consumers in 2022 to just 65% in 2025. The market appetite is there. Businesses are withdrawing from it out of fear, and taking credibility down with them.

The Competitor Who Communicates Well Wins

Greenhushing creates an opportunity for competitors who have worked out how to communicate credibly. When a whole sector goes quiet, the business that continues to make clear, substantiated claims about real credentials becomes the default credible option.

This is particularly true in B2B markets, where procurement teams are actively looking for sustainability evidence. A supplier that cannot provide it, because they’ve been deliberately quiet, loses deals they could have won. The competitive gap isn’t always about who has done more. It’s often about who can demonstrate what they’ve done.

Why the Fear is Driving the Wrong Behaviour

The fear driving greenhushing is real, but it is focused on the wrong risk. Businesses are afraid of being accused of greenwashing; of making a claim that turns out to be wrong, overstated, or unverifiable. That fear is reasonable given the regulatory environment.

But the response — silence — doesn’t eliminate that risk, it just shifts it. And it adds new commercial and legal risks that companies aren’t accounting for when they make the decision to go quiet.

The root of the problem is that many businesses treat sustainability communication as binary: either you make bold claims, or you say nothing. That’s not the choice. The real option — the one that manages risk without creating it — is precision. Specific, qualified, evidenced claims carry far less regulatory risk than vague ones, and they communicate more effectively to customers who want substance over marketing language.

The direction of travel in both UK and EU regulation is towards precision, not silence. The CMA’s Green Claims Code, the EU’s Empowering Consumers for the Green Transition Directive, and the ASA’s guidance all make the same underlying point: claims that are specific, qualified, and substantiated are permitted. The ones that attract enforcement are the broad, unverifiable, and generic ones. Greenhushing solves for the wrong problem.

What Good Sustainability Communication Looks Like in 2026

The goal is not to say more; it’s to say the right things. Businesses that have navigated this well are not making sweeping claims. They are making specific ones, tightly scoped to what they can actually evidence.

Replace Generic With Specific

Generic claims are the ones that attract regulatory risk and consumer scepticism. ‘Sustainable’, ‘eco-friendly’, ‘green’, ‘responsible’ — these create an impression without providing information. Replacing them with specific, verifiable statements is both safer and more persuasive.

Instead of ‘sustainably made’, say ‘manufactured in a facility certified to ISO 14001’. Instead of ‘carbon neutral’, say ‘carbon footprint independently assessed at X kg CO2e per unit under PAS 2050, with residual emissions offset via [specific verified scheme]’. The more specific the claim, the harder it is to challenge and the more trust it builds.

Scope Your Claims Accurately

Many businesses get into trouble by making a claim about one part of their operation that implies something broader. A product made from recycled materials is not automatically a sustainable company. Renewable electricity in your offices does not make your supply chain carbon neutral. Scoping claims accurately — saying what is true about what — reduces risk and avoids the overreach that invites challenge.

Communicate Progress, Not Perfection

One of the biggest misconceptions driving greenhushing is the belief that you can only talk about sustainability if you’ve got it completely sorted. You don’t. Consumers and buyers are increasingly comfortable with businesses that communicate honestly about where they are in a transition, what they have achieved so far, and what they’re working on next — provided that communication is honest and the commitments are real.

What erodes trust is not imperfection. It’s the gap between what a business claims and what it does. A business that says ‘we’ve reduced packaging waste by 30% since 2022 and we’re targeting 50% by 2027’ is making a credible, honest claim. A business that says ‘we’re committed to a sustainable future’ is saying nothing and risks saying something misleading.

Document What You’re Saying and Why

Whatever claims you make, hold the evidence. Know what certification, data, or methodology underpins each statement. Review claims when circumstances change. Build a short internal record of the evidence you relied on when you decided to make a claim. This protects you if a claim is challenged, and it gives you the confidence to make claims in the first place.

Frequently Asked Questions

We’re worried about getting greenwashing wrong. Isn’t saying nothing the safer option?

Only if you’re also comfortable with the commercial and legal risks of silence. Under UK consumer law, misleading omissions — withholding material information that a customer needs to make an informed decision — can constitute a breach. Beyond the legal dimension, staying quiet cedes ground to competitors and erodes trust with customers who are actively looking for sustainability evidence. The safer option is to make specific, substantiated claims — not to make none at all.

We haven’t got everything sorted yet. Can we still talk about sustainability?

Yes — as long as what you say is accurate and scoped correctly. Communicating genuine progress, specific achievements, and realistic targets is entirely legitimate. What gets businesses into trouble is claiming to be something they’re not, or implying a level of progress that isn’t evidenced. You don’t need to have reached net zero to talk about what you’ve reduced. You need to be accurate about what you’ve actually done.

What if a competitor makes bigger claims than we do — won’t silence make us look worse?

Possibly, yes. If a competitor is making sustainability claims in your market and you’re saying nothing, some customers will conclude the competitor is the more sustainable option — regardless of the facts. The answer isn’t to match their claims. It’s to make your own, specific, evidenced claims that speak for themselves. A precise, verifiable claim outperforms a vague one every time — and it carries far less risk.

We’ve heard ESG is becoming politicised. Should we avoid the language?

The language, perhaps — but not the substance. There’s a reasonable case for moving away from ‘ESG’ as a term, particularly if your audience associates it with large-cap investment debates rather than practical business operations. But removing the language while maintaining the substance is very different from going quiet entirely. Talk about what you’re actually doing: reduced waste, lower energy use, responsible sourcing, honest product claims. That’s not political. That’s just accurate business communication.

What’s the difference between greenhushing and just being modest about sustainability?

Modesty means not overclaiming. Greenhushing means not claiming at all — or actively suppressing communication about real progress out of fear. The first is good practice. The second is a strategic error. If you have genuine sustainability credentials and you’re withholding them from customers who would value them, that’s not caution — it’s a missed opportunity with its own set of risks attached.
