The plastic and glass paradox
In a report, Publicis Groupe Switzerland, the University of St. Gallen, and Grownate AG show that customers and companies rarely see eye to eye on the issue of sustainability. We spoke with two of the report’s authors.

m&k: Alexander Haldemann, in August you presented your «Scopes Report» to the media and the public. What were the initial reactions?
Dr. Alexander Haldemann: There were companies that reached out to us because they ranked at the top of the perceived sustainability rankings. They were, of course, happy and positive. But we were also contacted by some clients and non-clients of our agency group who ranked lower on the perceived sustainability list. They said, «That’s remarkable. We’d like to understand why.» In this way, the report fulfills a purpose we defined from the outset: to narrow the gap between companies’ sustainability activities and consumers’ perceptions. In short—we’re really pleased with the initial reactions.
You hinted at it yourself: «Scopes» does not evaluate what Swiss companies are actually doing in the area of sustainability—rather, it focuses on how the public perceives these companies. And it asks company executives what challenges they face in communicating their sustainability efforts.
Exactly. I’m convinced that sustainable business practices are the major challenge of our time. Only when consumers understand companies« efforts in this area can they make informed—that is, sustainable—decisions. Clear communication helps consumers choose the »right” brands—but to communicate clearly, you first have to understand what people want to hear.
«I am convinced that sustainable business practices are the greatest challenge of our time.»
What have you found out about this?
A major issue on the minds of the Swiss is recycling. For people in our country, recycling is a practical way of protecting the environment in their daily lives. For example, I have a colleague who returned to Switzerland after twenty years in Australia and told me how much he was looking forward to finally sorting his trash again (laughs). The origin of a product—we like to refer to «Swissness» in professional communication—is also associated with sustainability by consumers. And, this particularly surprised me: It’s by no means the case that only younger consumers evaluate companies based on perceived sustainability. Rather, it is older people in particular who give this topic serious thought—who consider what kind of world they’re leaving behind for their children and grandchildren and how their consumption habits help shape that world. Companies can use all these insights to tailor their communication to their customers’ interests.
What’s interesting is that, in some cases, there is a huge discrepancy between companies’ actual sustainability efforts and how the public perceives them. Nestlé, for example, has been deeply committed to sustainability for years and can prove it. Nevertheless, the participants in your study perceive Nestlé as not very sustainable.
Prof. Judith Walls: In fact, Nestlé is one of the companies that, according to our study, is not perceived as very sustainable. However, when you look at Nestlé’s specific sustainability efforts, it becomes clear that they are further along in this area than many other companies. This illustrates the gap between brand perception and corporate reality that Alexander mentioned earlier.
What might be the reasons for this gap?
The example of Nestlé highlights several aspects that also apply more generally to how companies are perceived in terms of sustainability. For instance, a company’s past plays a role. We all know that Nestlé has been involved in activities that have severely damaged its reputation. The same applies to public statements made by company representatives. A damaged reputation is very difficult to repair. At the same time, consumers unfortunately know less about actual sustainability efforts than many companies believe or would like them to. Here’s an example: During the energy crisis at the start of the war in Ukraine, many companies received angry calls and letters because they were allegedly leaving the lights on too long. People noticed this during their evening walks. The companies then responded by turning off the lights earlier, even though they say: «The savings are actually marginal; the lighting was already as efficient as possible before we turned off the lights an hour earlier.» As you can see, consumers judge things from a first-person perspective; they weigh emotions more heavily than facts.
That reminds me of another example: In the public eye, glass tends to be seen as a good choice for packaging, while plastic is seen as a bad one. But it's not that simple, is it?
No, it’s not that simple. This highlights the role that media coverage plays in shaping consumer perceptions: We all keep reading articles about how bad plastic is—and, of course, the material has numerous drawbacks. But to give a concrete example: This afternoon, I’m taking my students on a field trip to Coca-Cola. While preparing for the trip, I had the opportunity to review the company’s internal life-cycle assessments of various types of packaging. It’s very interesting to see just how detailed the trade-offs are that Coca-Cola has to make between glass and plastic packaging. How thin can a glass bottle be so that it doesn’t break during transport, yet still allows as many bottles as possible to fit into a truck to reduce transport emissions per bottle? If you use plastic, it might be easier to transport, but that brings other problems, such as recycling. And those are just two factors—there are dozens more. In the end, consumers only see the product—not why it was packaged and designed the way it is when it hits the shelves. Somehow, that has to be distilled into a simple slogan—luckily, that’s not my job, but Alexander’s (laughs). AH I just thought of a great headline for our conversation: The Plastic-Glass Paradox (laughs). By the way, I’m not entirely blameless when it comes to the perception of glass as good and plastic as bad: At our agency events, our credo used to be that we’d use only glass bottles. I now know that PET bottles can be a more sustainable solution. Making that switch internally is one thing—but packaging it into a clear and effective marketing message for the agency group’s clients—that’s the real challenge.
«Consumers place greater weight on emotions than on facts.»
This is a challenge that companies themselves are also aware of. For «Scopes,» you examined not only consumer perceptions but also the internal perspective of the companies, speaking with their sustainability managers. What insights did you gain from that?
First of all, the challenges in sustainability communication vary greatly from company to company. We’ve already discussed consumer perception—that is, the B2C component. For companies, however, there’s also the B2B component, where communication needs are completely different and different rules apply. Depending on which group is the focus, companies must tailor their communication of sustainability efforts differently to their buyers and suppliers. Furthermore, there is another challenge: Who actually communicates what a company is doing in terms of sustainability? It is rare to find «all-rounders» who, as sustainability experts, also possess professional communication skills—or vice versa. Communication professionals are often generalists. On top of that, different people are involved in various aspects of sustainability throughout the value chain: someone from the legal department, from the innovation division, from operations, and so on. Everyone has different content to communicate. On top of that, the messaging must be tailored differently for B2B or B2C audiences. As you can see, this is highly complex.
«A carefully thought-out simplification doesn't pose a risk of a social media backlash.»
What can communications agencies do to mitigate this complexity?
Haldemann: I am firmly convinced that our primary mission is an educational one. We need to explain to companies what consumers want to hear—and then show them how they can simplify the complexity of their sustainability efforts in their communications. Of course, I don’t want to take away anyone’s scientifically and legally sound sustainability report—but we need to be clear: That’s a document for B2B partners, not for end customers. The latter want «infotainment»; they want easily accessible insights into the sustainability of a brand or a company. Whenever I say this, I repeatedly hear corporate executives express concerns about greenwashing. Along the lines of: «If we don’t provide enough detail, people will end up holding that against us and we’ll run into huge problems.» But fear is a poor guide, and a carefully crafted simplification doesn’t pose a risk of a social media backlash. Not communicating at all—that’s the much bigger problem. JW And maybe—every now and then—we could make the complexity itself the topic of discussion? Maybe we could also just talk about the fact that, when it comes to some sustainability issues—going back to glass and plastic—there’s no one-size-fits-all solution, but rather that decisions have to be made on a case-by-case basis? Maybe we could also tell people that we’re working on better packaging; that we’re continuously investing in development, but that research takes time? As a consumer, I’d much rather hear something like that than hear nothing at all.
«Maybe—every now and then—we can make complexity itself the subject?»
