Purpose: The purpose of this study is to explore the factors that influence consumers to act socially responsible (CnSR) to provide guidance for CSR work practices in the context of fast food. Method: To answer the research questions a qualitative method has been used where empirical findings have been collected through secondary data and 16 semi-structured interviews. The study has been guided by a deductive approach where an analytical framework, based on previous research, has been the basis when collecting and analyzing the data. Conclusions: One conclusion that can be drawn is that fast food companies are working with the environmental aspect of CSR. Although, the current efforts are not enough to encourage consumers’ socially responsible (CnSR) behavior. Another conclusion of this study is that even though consumers have a positive attitude toward CSR, internal and external factors, especially environmental knowledge, motivation, and economic factors, have an influence on CnSR behavior not being achieved in the context of fast food. Value was the only factor that seemed to result in CnSR behavior. For this reason, fast food companies should provide more concrete information and offer smaller menus or trial samples at a lower price to increase consumers’ motivation to behave socially. Consequently, this could also make them value the more sustainable products in the future. Lastly, another conclusion is that Consumer-Company congruence (C-C congruence) was not achieved as there existed a lack in consumer CSR credibility and consumer CSR awareness. Based on this, it is obvious that fast food companies need to improve both their marketing communication on social media and their in-store promotion.

Företags samhällsansvar (Corporate Social Responsibility, CSR) är ett väl debatterat begrepp som uppmärksammats allt mer i bland annat media, men även av företag. Däremot är begreppet konsumenters samhällsansvar inte lika uppmärksammat trots att det finns en interaktion mellan konsumenters- och företags samhällsansvar. Forskare framhåller att det finns bristfälligt med teorier om konsumenters samhällsansvar samt att definitionen är viktig för att fortsätta driva CSR-debatten, vilket gör ämnet relevant att studera. Studien syfte är att med utgångspunkt i samhällsansvarsmodeller på företagsnivå, utveckla en definition och en tentativ samhällsansvarsmodell på konsumentnivå. Slutsatsen baseras på en kvalitativ undersökning utifrån 15 intervjuer samt teorier som behandlar definitioner och modeller om samhällsansvar. De ansvarsområden som identifierats och illustreras i KSA-modellen, konsumentens samhällsansvarsmodell, är det legala ansvaret som är tvingande och de två frivilliga områdena socialt ansvar och miljöansvar. Dessa tre områden består av en etisk grund och ett hållbart tidsperspektiv. Det sociala ansvaret och miljöansvaret består även av två underkategorier, ekonomi som visar förutsättningarna för att ta samhällsansvar och filantropi som visar på hur de två ansvarsområdena kan tas. De ansvarsområden som illustreras i KSA-modellen har framtagits med hjälp av konsumenters faktorer och motiv till att ta samhällsansvar. De faktorer som har identifierats är kunskapsfaktorn, hälsofaktorn, omsorgsfaktorn, tvingande faktorn, ”ta-ställningsfaktorn”, certifieringsfaktorn, självkänslofaktorn, empatifaktorn och inkomstfaktorn. / Corporate Social Responsibility, CSR, is a concept that is gaining more attention in the media as well as by companies. However, the consumer social responsibility has not gained the same attention, even though there exists an interaction between the corporate social responsibility and the consumer social responsibility. Researchers emphasize that there is a shortage of theories on consumer social responsibility, and that there is a need for a definition to drive the CSR debate. The purpose of this thesis report is to define such a definition as well as define a tentative social responsibility model on a consumer level, based on models for social responsibility on a corporate level. The conclusion is based on 15 interviews as well as theories, definitions and models of social responsibility. The areas of responsibilities that have been identified and that are illustrated by our CNSR (consumer social responsibility) model are the enforcing legal responsibility and the two voluntary social responsibility and environmental responsibility. These three areas of responsibility consist of an ethical foundation as well as dimension of sustainability. The social and environmental responsibilities further consist of an economical aspect that show the conditions to take responsibility and philanthropic aspect that show how these responsibilities can be taken. The areas of responsibility in the KSA model have been derived from consumer factors and motives for taking a social responsibility. The factors that have been identified are knowledge factor, health factor, care factor, enforcement factor, "take-a-stand"-factor, certification factor, self-esteem factor, empathy factor and income factor.
