Greenwashing isn’t always a lie. Sometimes it’s just bad design.

There's a company you should know about. Their emissions are down 60% since 2018. Their supply chain is third-party audited. Their net zero target is backed by a credible science-based pathway. Yet after visiting their website… you're not convinced.

There is a paradox at the heart of sustainable manufacturing's communication problem. The greenwashing conversation has focused almost entirely on what companies say: the language of pledges, certifications, and commitments. Almost none of it has focused on how design independently builds or destroys credibility, regardless of the substance behind the claims.

But there is such a thing as misguided greenwash: when your communication isn't fully thought through, you sometimes send unintentional signals, and at huge cost: distrust.

Let's look into that. And particularly, the role your website plays.

What your nervous system decides before your brain catches up

Here's the neurological reality of a website visit: 94% of first impressions are design-related, with only 6% attributable to actual content. Visceral credibility judgements emerge without rational cognitive processes, operating at the level of the nervous system rather than analytical thought. Your audience has decided how much to trust you before they've read a single word.

In practice, this means that if your genuine net zero commitment isn't backed by immediately available data, accessible via a visible and engaging button, but is instead say set over a stock photo of a wind turbine, and worse, forces you to hand over your email address just to learn about the technology… you enter murky perception territory. 

Every typographic choice, every photograph, every colour decision, every piece of whitespace is communicating before a single claim is made. And equally, the website visit experience, from button placement to product page, leaves a unique and lasting impression that will automatically shape your brand perception.

Greenwashing is a dark pattern with a sustainability logo on it

We've become increasingly familiar with greenwashing imagery red flags. The use of green leaf motifs, recycled-paper textures, or eco-labels created by the company itself exploits the symbols we've learned to associate with sustainability, regardless of whether any genuine commitment sits behind them. And that's often where the problems start.

An example? Take H&M's Conscious Collection: the Norwegian Consumer Authority found its sustainability marketing misleading not because the claims were entirely fabricated, but because the visual and tonal language of the campaign dramatically overstated the environmental significance of what was, in reality, a small fraction of their overall production. The design did the lying, even when the words were technically defensible.

When it comes to website experience design, there is such a thing as "dark patterns", a term coined by cognitive scientist Harry Brignull in 2010 to describe interface features crafted with a sophisticated understanding of human psychology, but deliberately not in the user's interests. 

In practice, that can mean trapping users into renewing subscriptions by failing to notify them in advance. Or using wording that misleads users into thinking they're opting out when they're actually opting in. It can mean highlighting certain CO2 emission savings while hiding others in small print, or forcing users to hand over their email address to continue the experience.

But it can be more subtle, for example leveraging interface interference such as low contrast to steer users away from certain choices. For example, in 2019, Tesla got under scrutiny as its mobile app visually encouraged users to purchase vehicle upgrades, while the displayed disclaimers appeared in faint, hard-to-read text, leaving users unaware of key terms, including the statement ‘upgrades cannot be refunded’... Yet another reason to really pay attention to accessibility standards.

The regulatory net is closing on both fronts

What makes this moment urgent is that the legal landscape is catching up simultaneously on two tracks.

On greenwashing: the EU's Green Claims Directive and the UK's forthcoming sustainability disclosure rules are moving the conversation from aspiration to accountability. An Italian court recently fined Shein's European operation €1 million after finding their sustainability messaging was vague, generic, and misleading, with net zero targets contradicted by actual emission increases. Regulators are now looking not just at what is claimed, but at how prominently it is displayed and what is omitted.

On UX ethics: the EU's Digital Services Act and tightening FTC enforcement are actively targeting deceptive interface design: the same dark pattern logic applied to flows and conversions. For the first time, how a sustainability claim is designed and presented is becoming a legal matter as much as a reputational one.

For sustainable manufacturers, these two regulatory pressures are converging on the same point: the design of your digital presence is no longer just a marketing question. It is increasingly a compliance question.

The opportunity in the gap

Here's what's striking about this landscape: the bar for designed credibility in green manufacturing is still… very low. Most competitors are still producing generic, stock-heavy, spec-forward websites that communicate nothing distinctive about what they believe or how they work. Which means the companies that invest in honest, specific, well-crafted design right now aren't just communicating better: they're differentiating in a way that is genuinely hard to copy, because it requires substance to back it up.

You cannot fake specificity. You cannot stock-photo your way to a credible mangrove restoration story. You cannot hire an AI to generate the faces of the people who work in your facility. Real design, grounded in real substance, is the one brand asset in sustainable manufacturing that companies without that substance simply cannot replicate.

The regulatory pressure will keep tightening. The investment community's tolerance for vague sustainability claims will keep shrinking. And the audience's ability to distinguish performed authenticity from the real thing will keep sharpening.

The million-pound question for sustainable manufacturers isn't whether to invest in honest, specific, well-designed communication. It's how long you can afford to look like everyone else while you wait.

Your early diagnosis.

If you feel like your website experience isn’t as clear and straightforward as it should be, you can start by taking our early diagnosis quiz!

One last thing: if you’re not sure how to answer the questions… a great place to start is to simply ask your users directly. User testing can be extremely enlightening to understand where things are not as clear as they should be. More on this in the next chapter of this series!

Next, we’ll talk about actual best practices to make sure your website is as transparent and appealing as it should be. Stay tuned.
