The aim of the research was to investigate how to stimulate sustainable consumer behaviors that lead to a lowering of the carbon footprint. Because of environmental challenges at the individual and societal levels, researchers agree that behavioral change is necessary. We argue that when already performing a sustainable behavior, this behavior can spill over to other sustainable actions, even to more difficult ones. First, we studied whether a positive behavioral spillover occurs between product categories and whether the spillover effect depends on the ease or difficulty of the sustainable behavior. Second, we investigated whether high awareness of sustainability determines the spillover between categories. We conducted three online experiments in Central Europe, investigating whether spillover takes place between behaviors assigned to the same category (transport or food) or between behaviors assigned to different categories (transport or food). In all three studies participants had to make two independent decisions. In studies 1a (N=281) and 1b (N=195), the effect of the ease/difficulty of the behavior was tested. In study 2 (N=164), awareness of CO2 emission reducing effects was manipulated. Findings revealed a behavioral spillover between sustainable choices.

In this thesis, authors’ main goal is to test two hypotheses to compare if the tourists are more likely to make their destination choice based on user generated photographs on social media, as well as, tourists’ sustainable destination choice based on photographs with sustainable green content. The quantitative research method was used to conduct the survey with experimental design. It was aimed to compare the tourist’ trust in different photo types, the consumers’ trust was expected to be measured by three dimensions: first impression, intention, and persuasiveness, recommended by previous studies. However, the findings revealed that the tourists are not more likely to trust user generated content on social media to make their destination choice.

Sustainability is a topic paying a visit to most industries today and the fashion business is no exception.The development of eco-efficient stores is one of the efforts carried out by Inditex Group with the aim to adopt sustainability into its practices. Such stores distinguish themselves for saving electricity, water and by greatly reducing the amount of CO2 that is yearly produced. The concept was initiated with the Zara brand but it will be introduced to the other six brands that integrate Inditex as well. However, despite the reduction in the carbon footprint it cannot be denied that the fast fashion business model creates a paradox in terms of sustainability.The following is a case study on the Zara Rome eco-efficient store. Being a store benchmark in Europe, it explores how the sustainability concept is communicated through this model and if the identified paradox is addressed. To do so, the study analyzes the external, internal and interactive marketing of the eco-shop based on the service marketing triangle theory and the Mehrabian-Russell stimulus-response model used in visual merchandising. Participant observation on site and a content analysis of relevant documents were carried out as research methods in order to find the messages emitted on each side of the triangle.The analysis shows that the paradox in the Zara eco-shops is not being handled at the customer level, though it is being handled at internal and external levels. As a conclusion, the eco-shops effort is part of a sustainability strategy with long term perspective and it will be addressed at customer level when the company as a whole counts with a more sustainable brand identity. Additionally suggestions are offered to potentialize the communication of sustainability in an eco-shop. / Program: Master in Fashion Management with specialisation in Fashion Marketing and Retailing

Med klimatförändringar som hotar människor, djur och natur, är frågan om ekologiskhållbarhet växande, speciellt inom konsumtion. Konsumtion lämnar idag ett stort miljö avtryck från produktion, konsumtion och leveranser, och i takt med att samhället blir mer digitaliserat, är det allt fler köp som sker via e-handeln. Detta medför att ekologisk hållbarhet blir allt viktigare inom e-handel och det ställs ett stort ansvar på konsumenter att följa hållbara beteenden. Trots att ekologisk hållbarhet blir viktigare, misslyckas många människor att följa hållbara vanor, vilket medför större efterfrågan om ökat ansvar och uppmärksamhet om hållbarhet. Övertygande design kan övertyga konsumenter till att följa hållbara beteenden och ändra på vanor som är ohållbara. Studien har utförts med hjälp av en designorienterad forskningsansats, där en prototyp har skapats utifrån fyra designprinciper från ramverket Persuasive systems design (PSD). Dessa designprinciper har applicerats i en e-handelskontextmed ett urval av städ- och hygienprodukter, i syfte att övertyga användaren till att köpa hållbara produkter över icke-hållbara produkter. Som resultat presenteras fyra designförslagför hur designprinciperna: självövervakning, trovärdighet, socialt lärande och förslag kan designas för att motivera användare. Självövervakning kan designas med progressiva mål och betydelsefulla belöningar. Trovärdighet kan använda tredjepartscertifierade märkningar och konkret information om hållbarhetsapekter. Socialt lärande kan presentera hållbara produkter som populära när de köpts med hög frekvens av andra konsumenter. Slutligen kan förslag på hållbara produkter riktas till användare med hållbarhetsintresse. / With climate change that threatens humans, animals, and nature, the question of ecological sustainability is growing, especially in consumption. Consumption today leaves a large environmental footprint from production, consumption, and deliveries, and as society becomes more digital, more and more purchases are made via e-commerce. This means that ecological sustainability is becoming increasingly important in e-commerce and a great responsibility is placed on consumers to follow sustainable behaviors. Although ecological sustainability is becoming more important, many people fail to follow sustainable habits, which leads to greater demand for increased responsibility and attention to sustainability. Persuasive design can persuade consumers to follow sustainable behaviors and change their unsustainable habits. The study was carried out with the use of a design-oriented research approach, and a prototype was created based on four design principles from the framework Persuasive systems design (PSD). These design principles have been applied in an e-commerce context with a selection of cleaning and hygiene products, to persuade the user to buy sustainable products over non-sustainable products. As a result, four design proposals are presented for how the design principles: self-monitoring, credibility, social learning, and suggestion, can be designed to motivate users. Self-monitoring can be designed with progressive goals and significant rewards. Credibility can use third-party certificates and concrete information about aspects of sustainability. Social learning can present sustainable products when they are frequently purchased by other consumers. Finally, suggestions on sustainable products can be presented to users that have an interest in sustainability.
