(2015) point out that customers are very social animals, belonging to categories which each have a well-defined identity, so, according to Garabedian (2007), they can be considered as heterogeneous agents in the face of societal problems.
Roughly three categories of consumers can be distinguished. The first corresponds to consumers who are part of a rationality whose core is instrumental (selfish) in consuming “socially responsible” products. They may give priority to CSR practices that “manufacture” attributes that improve the intrinsic quality of the product and provide them with a tangible individual private benefit. These consumers may agree that it is important for companies to develop CSR practices, but they refuse to accept the consequences, that is, higher prices, lower quality products (Carrigan and Attala 2001) and a negative image. This is the case, for example, with luxury clothing, as Achabou and Dekhili (2013) have shown that consumers perceive products made from recycled materials negatively (i.e. have a negative image of them). Selfish consumers are motivated more by their own interests (well-being) than by those of society (d’Astous and Legendre 2009). The second is made up of consumers who adopt a rationality whose core is “hybrid” (instrumental and axiological), that is, they are interested in the societal practices of the company that bring them a tangible individual private benefit (health and well-being, etc.), while generating a collective benefit. They are concerned with societal practices that “produce” attributes that improve the intrinsic quality of products (instrumental rationality) but are also sensitive to the reduction of negative social and environmental externalities or the generation of positive externalities (axiological rationality). Finally, the third category concerns consumers whose behavior is axiologically rational and who are motivated by the extra-economic dimensions of the purchasing act (Desjeux 2003). For them, the purchase is not limited to the need for use, but responds to a broader satisfaction that includes moral satisfaction. It is a question of giving meaning to their act of purchasing, so consuming “socially responsible” products enables them to achieve the ethical values which they aspire to hold. For d’Astous and Legendre (2009), “these consumers are people who take into account the societal consequences of their consumption and use their purchasing power and their purchasing act to influence society”. They are interested in the moral rules of the market economy and think that companies should preserve the environment and respect social values (François-Lecompte and Valette-Florence 2006). It is the intangible attribute embodied by the virtue of improving a company’s civic image that is valued. These consumers express militant or political positions in their commercial choices, especially, according to Tirole (2009), if the visibility of their altruistic consumption is high.
2.4.3. Factors determining consumer eco-responsibility
This seems to be a good time to launch sustainable offers, and most consumers seem to appreciate environmentally friendly products and services. However, according to White et al. (2020), “a recent survey shows that 65% of consumers of them say they want to buy brands committed to sustainable development, but only 26% actually do so”. This gap between intention and action needs to be reduced in order to achieve the sustainable development goals of companies, as well as sustainable development across the world as a whole. Unilever estimates that approximately 70% of its GHGs depend on the types of products sold, their use and the recycling of packaging in an environmentally responsible manner. In recent years, the authors have “conducted their own experiments and used the interventions of legislators, marketing, economic and psychological research to find ways to encourage sustainable consumption, thus matching consumer behavior with the principles they espouse”. They identified five actions that companies can use.
The first concerns the use of social pressure. White and Simpson advised the City of Calgary in Alberta, Canada, who wanted to improve the recycling of grass clippings from lawns, “to try to change people’s attitudes by using “social norms”, that is, tacit conventions that define acceptable behavior in a group and that people must respect if they want to fit in.” Social pressure is an extension of the theory of engagement. For example, White, Simpson and the city conducted a field study on messages that had been posted on the doors of residents’ homes (“Your neighbors recycle grass. You can do it too”) and observed that in two weeks, the grass recycling rate of residents was double that of a control group. Moreover, advocates of sustainable behavior are more convincing when they themselves have adopted such behavior. According to White et al. (2020), a study found that 63% more people invested in solar panels when a supporter of these products explained the reasons that they had installed them in their own home. On the other hand, “social norms may not appeal to some consumers, such as men who associate sustainability with femininity and reject it, unless a brand is already linked to masculinity and virility”. For example, Jack Daniel’s14 integrates sustainability into its brand strategy (sale of residual products and unused resources, no landfill) and links sustainability, quality and taste. In general, “social pressure can increase if sustainable behaviors are made more visible (no waste to be recycled or composted in a transparent garbage bag), more public (sticker on a car windshield indicating that the engine should be turned off while waiting for a child to leave school), or competitive (singling out students who compost to encourage others to do the same)”.
The second step is to promote good habits. People have routines for moving, buying, eating and recycling products and packaging. “Sustainable consumption behaviors require breaking bad habits, which are often due to signals in familiar contexts.” For example, using a disposable coffee cup (a habit repeated 500 billion times a year worldwide) can respond to signals such as a disposable cup offered by a bartender, or a trash can with a picture of a cup on it. “Companies need to improve the design of their products, but above all make sustainable behavior a default choice.” In Germany, researchers have found that 94% of people conserve clean electricity when it is supplied by default in residential buildings. This approach shows that this type of strategy can be generalized for other areas of activity. For example, making green alternatives such as reusable hand towels and electronic bank statements the default option can increase the rate of take-up. In California (United States), restaurants offer beverages without plastic straws as part of their dining service in order to limit customer demand for straws. White et al. (2020) propose three techniques for developing good habits. Incentives in the form of simple written messages can remind people of behaviors that they should develop in certain places, such as encouraging recycling near appropriate bins. Feedback can provide indications of repeated behaviors such as on fuel consumption and mileage when driving a vehicle. Sustainable motivation levers may be different for different companies. For example, in the UK, Coca-Cola and Merlin Entertainments have installed “reverse vending machines” to recycle plastic bottles and allow consumers to benefit from half-price entrance tickets to amusement parks. “Yet if these levers are removed, the desired behavior may disappear. They can also destroy consumers’ intrinsic desire to change behavior.” Researchers have found that external incentives (“Save money!”) combined with intrinsic motivations (“Protect the environment!”) lead to less desire for a sustainable product than intrinsic motivations alone. “An external incentive could therefore have a ‘crowding out effect’ on an intrinsic motivation. However, major changes in people’s lives, such as moving, changing jobs, etc., cause them to change their habits.” A study was carried out on 400 households that had recently moved, and another 400 households that had not moved. Half of the households in both groups attended an interview and received samples of environmentally friendly products and information on sustainable development. The adoption of green behaviors was more likely among households that had moved than others.
The third step is to take advantage of the domino effect. “If consumers are encouraged to develop environmentally responsible habits, positive effects can logically be brought about. By deciding to behave in an environmentally friendly manner, they are likely to make other changes that are beneficial to society.” White et al. (2020) report that Ikea launched a sustainability initiative, Live Lagom (lagom means “the right amount” in Swedish), and then studied the journey of a core group of its customers. The company found that although they started by reducing food waste, they often continued to work on other areas, such as
