It was a Tuesday morning, and I was standing in a café near my university, holding a “compostable” coffee cup. The brand had printed a small green leaf on the side, and I felt virtuous — I was doing my bit for the planet. Then I noticed the small text on the bottom: “Commercially compostable only.” I looked around the café. There was no compost bin. There wasn’t even a recycling bin. That cup, I realised, was destined for landfill, where it would sit for decades, its green leaf a tiny, meaningless promise. I started to notice similar patterns everywhere: fashion brands trumpeting their “sustainable lines” while churning out fast fashion, banks pledging net‑zero while funding coal, supermarkets wrapping organic vegetables in plastic. I was studying business, and I began to wonder: what does sustainability actually mean for a company? Is it a genuine transformation of how business works, or just a new language for the same old profit machine? That coffee cup became the starting point for a question I couldn’t stop asking, and eventually, for my dissertation.
When I began researching sustainability in business, I was overwhelmed by the sheer breadth of the topic. I could examine corporate social responsibility reporting, the circular economy, greenwashing, supply chain ethics, renewable energy adoption, or the role of investors in driving change. I needed a specific, researchable question that felt both practical and urgent. I started by exploring what other students had already investigated, and I came across a collection of sustainability in business dissertation topics (you can browse them here: https://premierdissertations.com/sustainability-in-business-dissertation-topics/) that helped me see the landscape. Some projects analysed how consumers respond to sustainability claims, others examined the barriers to implementing circular business models, and a few explored the relationship between environmental performance and financial returns. That breadth gave me the confidence to settle on a question that felt directly connected to my café experience: how do UK consumers interpret and respond to corporate sustainability messaging, and what factors determine whether that messaging builds genuine trust or provokes cynicism?
Once I had my direction, I designed a mixed‑methods study. I surveyed over 350 consumers, presenting them with different types of sustainability claims — from vague statements like “eco‑friendly” to specific, verifiable commitments like “carbon neutral, certified by a third party.” I also interviewed a smaller group, asking them to describe how they felt when a brand they trusted was accused of greenwashing. The findings were revealing. Consumers were far more sceptical than many marketers assumed. Generic claims without evidence generated cynicism rather than loyalty, while transparent, specific claims — even when modest — built trust. One participant told me, “I don’t need a company to be perfect. I just need them to be honest.” My dissertation argued that authentic sustainability communication is not about making grand promises but about demonstrating progress, acknowledging limitations, and inviting consumers into the journey. Brands that do this, I found, are rewarded with loyalty; those that don’t are punished, sometimes irreversibly.
Writing that dissertation changed the way I consume, and the way I think about business. I no longer believe that sustainability is a separate “department” or a marketing strategy. It is, or should be, the core of how a company operates — how it sources, produces, distributes, and communicates. If you’re considering a sustainability in business dissertation, I’d encourage you to start with a moment that made you question a company’s promise — a label, an advertisement, a claim that felt too good to be true. The best research questions grow from a sense that business as usual is no longer enough, and that the next generation of leaders must find a better way. Then explore what other students have already done, and let their work help you shape your own inquiry into something that could, in its own small way, help build an economy that works for people and the planet.
