AbstractThe way consumers behave is fundamental to marketing. Journal of Consumer Behaviour (JCB) is an international journal dedicated to publishing the latest developments of consumer behaviour. To gain an understanding of the evolution and trends in consumer behaviour, this study presents a retrospective review of JCB using bibliometric analysis. Using bibliographic records of JCB from Scopus, this study finds that consumer behaviour research in JCB has grown substantially in terms of collaboration (co‐authorships), global reach (countries), productivity (publications), and impact (citations). The major themes explored by consumer behaviour research in JCB include consumer information processing, consumption communities, consumption value, sustainable consumption, intergenerational consumer behaviour, consumer‐brand relationship, consumer ethics, and conditional relationships in consumer behaviour. The most recent consumer behaviour research in JCB has considered externalities such as the COVID‐19 pandemic and focused on themes such as consumer ethics and sustainable consumption in line with the global movement toward environmental social governance (ESG) and sustainable development goals (SDGs).

In this doctoral dissertation, I adress the issue of changes in foodways, using a socio-cultural framework, as this approach takes as a starting point the dynamic co-construction between the person and her or his environment. Within this framework, I place particular emphasis on approaches underlining the importance of dialogicity and socio-materiality in human activities. I select several conceptual tools that I consider as useful to analyze these processes of navigation of the world, namely positioning, rupture/transition, responsibility and creativity. The phenomenon that I examine with this theoretical framework is the elaboration of a foodway at an individual level and, more specifically, the questioning and refusal of products of animal origin, which, depending notably on the extent of the avoidance, might be labelled vegetarianism or veganism. I argue that this phenomenon is of high interest notably because it is at the core of societal debates and challenges related to animal ethics, environmental impact and health issues. In this thesis, I conceptualize changes in foodways as movements of repositioning in a foodscape (a landscape of discourses and practices related to food and eating) and I address the following research question: What are the positioning dynamics around the consumption of products of animal origin among people who changed their foodway regarding these products? In order to address this question, I use a qualitative approach allowing me to understand each situation and trajectory in its complexity and dynamicity. I propose a methodological design combining a narrative interview, a dialogical experiment, and a filmed observation. As a complement, I also collect elements from the socio-cultural environment such as newspaper articles. Participants are ten adults who changed their food habits in relation to products of animal origin.

To transition to a sustainable consumption environment, Ireland has articulated a variety of National framework plans and policies, yet several sustainability related indicators, such as resource efficiency, sustainable development goals twelve (SDG12) score and waste per capita positions Ireland at a low performance in comparison to other European Union countries. Identifying some of the drivers and barriers to sustainable consumption behaviour contributes to policy suggestions and target areas to stimulate the transition to a sustainable environment. This thesis analysed data from a survey of 318 Irish consumers to establish the presence of drivers and barriers to sustainable consumption behaviour. It applied three methodology steps accordingly, (i) Exploratory factor analysis (EFA) to establish and extract sustainable consumption variables and constructs, (ii) Confirmatory factor analysis (CFA) to validate and analyse established sustainable consumption variables and constructs, (iii) Ordinal regression to link drivers of sustainable consumer behaviour and socio- economic characteristics. Four constructs were extracted representing the drivers of sustainable consumption behaviour as: sustainable food purchasing, shopping planning behaviour, food waste behaviour, environmental awareness while one barrier was identified, purchasing influencers. The study finds shopping planning behaviour positively drives a decrease in food waste behaviour. Furthermore, men were identified as less likely to consume food sustainably, projecting the group as a target to stimulate the sustainability transition. Women were more sustainable food consumers as they were more likely to write a shopping list before shopping and were less likely to waste food after a meal, indicating consideration for a gender dimension when planning policy interventions to reduce food waste. People in rented accommodation, either shared or privately rented, were identified as another cluster that can be targeted in the transition towards stimulating sustainable consumption behaviour.

AbstractThis special issue of the Journal of Consumer Behaviour aims to contribute to the knowledge of the drivers of environmentally sustainable behaviour and the characteristics of green consumers. It consists of eight papers that represent a range of topics related to consumer behaviour and environmental sustainability. The special issue has several implications. First, environmentally sustainable behaviour is influenced by multiple motives and determinants, which include internal, social, situational and demographic factors. Second, the impact of such factors tends to vary across national and consumer context. Third, integrative and comprehensive models including mediators and/or moderators could be used to better understand the mechanism through which the various factors affect pro‐environmental behaviour. Fourth, green marketing initiatives (e.g., sustainable products, green advertising) could be used to promote consumer's pro‐environmental beliefs and behaviours. Finally, interventions aimed at influencing habit and promoting environmentally sustainable behaviour should be tailored to different target groups such as those with different personality dispositions, environmental concerns and levels of engagement in environmental practices at home.
