The Sustainability Paradox and How to Overcome It Using Insights From Consumer Psychology

Marketers are under increasing pressure to position their products as sustainable. Yet oddly enough, brands that emphasize sustainability too heavily often underperform — commercially and in their actual impact. The result? A slower, more frustrating transition to a sustainable consumption pattern.

This is the Sustainability Paradox.

A recent meta-review of 94 studies — When Sustainability Backfires — confirms it. Consumers don't always respond positively to bold sustainability messaging. In fact, over-communication can trigger confusion, skepticism, and even backlash.

Let’s unpack what’s going on — and how food brands can communicate more effectively without diluting their values.

Why Pushing the “Green” Message Too Hard Backfires

Intuitively, it makes sense to shout about your product’s sustainable credentials. You've invested time and effort in making something better — of course you want to talk about it.

But if the message is too loud or too prominent, unintended side effects kick in:

1. Information Overload

The market is saturated with green claims. When messaging becomes overwhelming or contradictory, consumers tune out. The result? Your core message gets lost and trust in your brand declines.

2. Skepticism and Perceived Greenwashing

If a brand shouts too loudly about sustainability — especially when there’s a gap between words and actions — consumers experience cognitive dissonance. They feel uncomfortable. They question motives. Especially for bigger brands, a legacy misstep can linger in the consumer’s mind. (Think of how FrieslandCampina, one of the biggest dairy companies in the world, once promoted its members as "climate-neutral farms" — a claim that didn’t quite land.)

3. Sustainability = Compromise?

Labelling a product as “sustainable” can (ironically) lower its appeal. Consumers may assume it’s less tasty, less functional, or less enjoyable. The message unintentionally says: “We sacrificed quality for ethics.” That’s not a compelling offer.

What the Science Says

That same review identified three key psychological mechanisms that explain why explicit sustainability messaging often falls flat:

• Information elaboration: Too many green claims reduce processing and trust, leading to negative brand evaluations.
• Product perception: Explicitly sustainable products are often seen as inferior in taste, quality, or aesthetics.
• Self-perception & social dynamics: People want to feel good about their choices — but not judged. “I don’t eat meat, but I don’t call myself a vegetarian,” is a conflict I experience myself. The label can feel limiting or awkward, or just not right.

How to Break the Paradox: 4 Principles for Smarter Sustainability Messaging

The good news? Cognitive psychology can help. By shifting how we talk about sustainability — not whether we talk about it — brands can avoid the pitfalls and strengthen consumer connection.

Here’s how:

1. Keep it Simple and Consistent

Integrate sustainability naturally into your brand story — not as an add-on or separate pillar. Avoid jargon and mixed messages. Clear, coherent storytelling reduces mental overload and builds trust.

2. Make it Subtle, Not Central

Instead of leading with sustainability, let it support your core value proposition. For example: Don’t make “organic” the headline. Make “local craftsmanship” your focus — with organic as a meaningful layer underneath.

3. Be Transparent and Realistic

Honesty beats perfection. Admitting what you're still working on builds credibility and defuses greenwashing concerns. Consumers are smart — they can spot spin.

4. Appeal to Self-Image, Not Guilt

People want to feel good and fit in. Sustainability messaging should support positive identity and reduce pressure, not make people feel like they’re being judged or tested.

Brands Putting It Into Practice

Veja — the French sneaker brand — nails it:

• Simple messaging: Stylish sneakers. Ethically made. No frills, no lectures.
• Subtle sustainability: Eco choices are embedded, not screamed.
• Real transparency: Open about costs, processes, and imperfections.
• Self-aware positioning: Wear Veja and feel good and look good — no sacrifice required.

In food, a great local example is Lazy Vegan (Netherlands). Their line?

“Ready in 8 minutes. 100% plant-based. No hassle.”

No overloaded claims. No green sermon. Just an effortless, everyday solution for people who care — but don’t want to overthink dinner. The name and packaging are all about ease and comfort, with sustainability as the added bonus.

Final Thought: If You Want to Drive Real Change, Don’t Shout

The paradox is clear: The harder you push the sustainability angle, the more resistance you might face. But with smarter, more psychologically attuned communication, sustainability becomes a quiet strength — not a loud burden.

For food brands, the challenge is not just to be sustainable — but to feel that way to consumers. Without triggering doubt. Without overwhelming. And without making it sound like a trade-off.

Sustainability doesn’t have to be center stage. It just needs to be real.
