Dr Sayed Elhoushy: Sustainability Marketing Isn’t the Problem; Poor Marketing Is
For years, sustainability and marketing have been framed as uneasy bedfellows.
One pushes for reduced consumption; the other, supposedly, exists to increase it.
This tension has shaped countless conversations inside boardrooms, classrooms, and agency strategy sessions.
Can marketing ever truly be sustainable?
When I recently spoke with Dr. Sayed Elhoushy, Senior Lecturer in Marketing at Queen Mary University of London, he offered a deceptively simple answer:
- It depends entirely on how we choose to practise marketing
- That distinction matters more than most organisations realise
- The overconsumption accusation
- The criticism isn’t unfounded
Traditional marketing has often operated as an amplification system for overconsumption, encouraging people to buy more, upgrade faster, replace sooner, and equate ownership with identity.
Seen through this lens, marketing has undeniably contributed to environmental pressure. Sayed’s own sustainability journey began with witnessing this firsthand.
During field training in a large hotel early in his career, he encountered industrial-scale food waste leaving restaurant kitchens every day; the scale shocked him.
That moment became the beginning of his research into sustainable consumer behaviour and food waste reduction, work that now informs his teaching and published research.
But his conclusion wasn’t that marketing should be abandoned; it was that it should be reimagined.
Marketing as a behaviour-shaping discipline
If your definition of marketing is “advertising designed to sell more products,” sustainability and marketing will always clash.
If your definition is broader, i.e. creating, communicating, and delivering value, then marketing becomes one of the most powerful tools available for sustainability transformation. That’s because marketers understand:
- Behavioural triggers
- Narrative framing
- Habit formation
- Social norms
- Cultural meaning-making
These are exactly the tools sustainability requires.
The challenge isn’t whether marketing belongs in sustainability; the challenge is whether marketers are willing to evolve their role.
The food waste lesson
One of Sayed’s most revealing examples comes from food waste research conducted with communities in Tower Hamlets.
On paper, households are responsible for around 60% of food waste at the consumer level.
That statistic seems to point to an obvious solution of changing consumer behaviour. But when speaking directly with households, another story emerged.
People weren’t carelessly wasting food, but they were consistently buying more than they intended, even when entering supermarkets with shopping lists.
The real culprit was a retail environment engineered to influence purchasing decisions through promotions, layout design, visual cues, scarcity framing, and behavioural nudges.
This reframes the problem entirely.
It’s not simply about educating individuals; it’s about recognising the systems that shape them. That’s where marketing becomes central.
Stop responsibilising the consumer
One of the most damaging tendencies in sustainability communication is what might be called responsibility dumping.
You’ve seen it:
- Fly less
- Waste less
- Buy better
- Recycle more
- Choose wisely
None of these messages is inherently wrong, but the problem is when they imply that sustainability failure rests primarily with individual consumers.
As Sayed notes, people are increasingly fatigued by being told they alone must solve systemic problems.
Eventually, communication fatigue becomes disengagement, then scepticism and then outright resistance.
This is one reason sustainability messaging so often fails, not because audiences don’t care, but because they feel unfairly burdened.
A better model: redesign the system
One of the most compelling examples we discussed was Stroodles. Rather than persuading consumers to make “better” decisions around single-use plastic cutlery, the company redesigned the product entirely by creating edible utensils.
No behaviour-change lecture required, no guilt-based messaging, no decision fatigue, just a fundamentally better system design.
This is sustainability marketing at its best, not persuasion, but transformation.
The marketer’s new brief
The future of sustainability marketing is not about making unsustainable systems sound responsible. It’s about helping organisations redesign value creation itself.
That means asking harder questions:
- Are we solving the problem upstream?
- Are we changing products, not just campaigns?
- Are we reducing decision friction?
- Are we creating behavioural ease?
- Are we designing for better defaults?
This is a fundamentally more ambitious role for marketing and a far more meaningful one.
The marketers who embrace it won’t simply communicate sustainability, they’ll help create it.
