The authors propose that purchasing luxury can be a unique means to engage in sustainable consumption because high-end products are particularly durable. Six studies examine the sustainability of high-end products, investigate consumers' decision making when considering high-end versus ordinary goods, and identify effective marketing strategies to emphasize product durability, an important and valued dimension of sustainable consumption. Real-world data on new and secondhand accessories demonstrate that high-end goods can be more sustainable than mid-range products because they have a longer life cycle. Furthermore, consumers engage in more sustainable behaviors with high-end goods, owning them for longer and disposing of them in more environmentally friendly manners. Nevertheless, many consumers prefer to concentrate their budget on multiple ordinary goods in lieu of fewer high-end products partly because of product durability neglect, a failure to consider how long a product will last. Although consumers generally believe that high-end products last longer, they fail to take such a notion into account when making purchases. Finally, this research offers actionable strategies for marketers to help consumers overcome product durability neglect and nudge them toward concentrating their budget on fewer high-end, durable products.

Why are men less likely than women to embrace environmentally friendly products and behaviors? Whereas prior research attributes this gender gap in sustainable consumption to personality differences between the sexes, we propose that it may also partially stem from a prevalent association between green behavior and femininity, and a corresponding stereotype (held by both men and women) that green consumers are more feminine. Building on prior findings that men tend to be more concerned than women with gender-identity maintenance, we argue that this green-feminine stereotype may motivate men to avoid green behaviors in order to preserve a macho image. A series of seven studies provides evidence that the concepts of greenness and femininity are cognitively linked and shows that, accordingly, consumers who engage in green behaviors are stereotyped by others as more feminine and even perceive themselves as more feminine. Further, men’s willingness to engage in green behaviors can be influenced by threatening or affirming their masculinity, as well as by using masculine rather than conventional green branding. Together, these findings bridge literatures on identity and environmental sustainability and introduce the notion that due to the green-feminine stereotype, gender-identity maintenance can influence men’s likelihood of adopting green behaviors.

Purpose This study aims to examine the role of message appeals (concrete vs abstract) posted by greenfluencers in determining their behavioral intention toward the sponsored sustainable product. This study examined the underlying mechanism of message authenticity and product sustainability image in this relationship. This study also investigated the boundary condition of product type (utilitarian vs hedonic) in the effect of sustainability message appeal on purchase intention. Design/methodology/approach Four studies were carried out. One field experiment on Facebook and three scenario-based online experiments were conducted to test the proposed relationships. Findings This study found that a concrete message appeal results in a higher purchase intention of the promoted product than an abstract message appeal. This effect is a result of message authenticity and product sustainability image. Furthermore, product type moderates the impact of message appeal on behavioral intention via message authenticity and product sustainability image. Research limitations/implications This study contributes to the literature on influencer marketing, sustainability communication and the persuasion process. Practical implications This study’s findings provide insights for greenfluencers and firms that leverage greenfluencers to promote their sustainable products on social media. Specifically, it lays out how the sustainability message should be framed to be persuasive. Originality/value This study findings offer novel insights for greenfluencers and firms in developing effective message strategies to promote sustainable products on social media.

Purpose The young members of Generation Z, who are hyperconnected and addicted to social media, are thought to be particularly sensitive to environmental and social concerns. This study aims to draw on a conceptual model that is based on the stimulus-organism-response paradigm. Exposure to sustainability content on social media is considered to be a stimulus that affects the development of sustainability advocacy among GenZers, who modify their lifestyles. Five hypotheses are developed and tested. The goal is to define the antecedents of sustainability advocacy. Design/methodology/approach A Web survey was distributed to 660 Italian members from Generation Z (aged between 14 and 25) to detect the frequencies of exposure to sustainability content on social media, sustainable habits, sustainable consumption behaviours and actions that are related to sustainability advocacy on social media. Correlation and multiple regression analyses were conducted to investigate the relationships between these factors. Findings The results show that exposure to sustainability content on social media affects both sustainable habits and sustainable consumption behaviour. These three factors influence the propensity to promote sustainability-related issues on social media and should, therefore, be considered to be antecedents of sustainability advocacy. Practical implications The study, which takes the social responsibilities of large companies into account, is conducive to understanding how brands can intervene in the soliciting processes of sustainability advocacy through social media to gain legitimacy and increase brand awareness. Originality/value This study is among the first to consider the use of social media for advocating sustainability among Generation Z, thus enriching academic research on this cohort.

In the face of the growing prevalence of multiple appeals to sustainable consumption in marketers’ sustainable product communications, we examine the efficacy, in terms of consumer reactions, of adding an extrinsic appeal (e.g., “Purchase this green product to save money!”) to an intrinsic appeal (e.g., “Purchase this green product to save the environment!”) based communication for a sustainable product. Three studies provide support for our basic assertion that, compared to an intrinsic appeal, joint appeals (i.e., an intrinsic and extrinsic appeal together) reduce consumer preference for sustainable products. As well, these studies demonstrate that this adverse effect of joint appeals is based on a lowering of consumers’ attributions of the company’s sustainability efforts to intrinsic motives (e.g., to the company’s genuine concern for the environment). Finally, not all consumers react adversely to joint appeals; relative to intrinsic appeals, such appeals increase, rather than decrease, the intrinsic attributions and sustainable product preferences for consumers with lower involvement with sustainable consumption.

Guilt appeals have been found effective in stimulating ethical consumption behaviors in western cultures. However, studies performed in Confucian cultural contexts have found contradictory results. We aim to investigate the inconclusive results of research on guilt and ethical consumption and to explain the inconsistencies. We aim to better understand the influence of guilt on ethical consumption in a Chinese Confucian context and to explore the culturally relevant individual-level concept of interdependent self-construal as a moderator. We build our argument on the Confucian ethics of ren-yi-li where the virtue of propriety (li ネ) specifies role-based obligations depending on the proximity of one's relationship to others and may thus limit ethical behaviors that are directed to those who are relationally distant. We hypothesize a positive relationship between guilt and ethical consumption that is, however, negatively moderated by interdependent self-construal. Put another way, consumers who define themselves strongly through their relationships with close others are less likely to compensate for guilt through ethical consumption. We find the hypothesized model supported in a survey of 314 Chinese consumers. The results suggest that guilt appeals can stimulate ethical consumption in Confucian cultures. However, guilt appeals may not be enough, as the moderating effect suggests that they will be most effective when combined with an ethical consumption initiative that conforms to the Confucian li principle. As this principle implies prioritizing close over distant relationships, it follows that consumers may be more likely to respond to guilt appeals which are linked to ethical consumption initiatives whose beneficiaries they feel connected to.

The theories of reasoned action and planned behaviour (TRA/TPB) have fundamentally changed the view that attitudes directly translate into behaviour by introducing intentions as a crucial intervening stage. Much research across numerous ethical contexts has drawn on these theories to offer a better understanding of how consumers form intentions to act in an ethical way. Persistently, researchers have suggested and discussed the existence of an intention–behaviour gap in ethical consumption. Yet, the factors that influence the extent of this gap and its magnitude have not been systematically examined. We, therefore, contribute to the debate on the intention–behaviour gap by reviewing the empirical TRA/TPB studies that have assessed both intention and behaviour in ethical contexts. The findings from our review show that few studies assessed the intention–behaviour relationship and as a result, there is limited empirical evidence to date to quantify more accurately the intention–behaviour gap in ethical consumption. Our second contribution aims to provide an empirical case study which assesses the magnitude of the intention–behaviour gap in the context of avoidance of sweatshop clothing and to assess the roles of planning and actual behavioural control in potentially reducing the intention–behaviour gap. The findings of our case study suggest that there is indeed a large gap between intention and behaviour, and we conclude by calling for more empirical longitudinal studies to assess the complex nature of the relationship between intention and behaviour.

As human consumption is one of the key contributors to environmental problems, it is increasingly urgent to promote sustainable consumption. Drawing on the agentic-communal model of power, this research explores how the psychological feeling of power influences consumers’ preference for green products. We show that low power increases consumers’ preference for green (vs. conventional) products compared to high power (Studies 1a and 1b). Importantly, we identify two factors moderating the main effect of power on green consumption. Specifically, we find that the effect of power on green consumption is more salient among those with high green consumption values (Study 2). In addition, the effects of power are dynamic as a function of power distance belief (PDB), such that low power (vs. high power) promotes green consumption in the low-PDB context while high power (vs. low power) promotes green consumption in the high-PDB context (Study 3). Taken together, these findings provide novel insights into understanding green consumption from the perspectives of social power, green values, and PDB. Besides contributing to the literature, the findings have significant implications for marketers and policy-makers in promoting green campaigns, bridging the attitude-behavior gap, and building a more sustainable society.

Purpose This paper aims to explore why consumers absorb ethical habits into their daily consumption, despite having little interest or understanding of the ethics they are buying into, by looking at the motivation behind mainstream ethical consumption. Design/methodology/approach Fifty in-depth field interviews at point of purchase capture actual ethical consumption behavior, tied with a progressive-laddering interview technique yields over 400 consumption units of analysis. Findings Ethical attitudes, values and rational information processing have limited veracity for mainstream ethical consumption. Habit and constrained choice, as well as self-gratification, peer influence and an interpretivist understanding of what ethics are being purchased provide the primary drivers for consumption. Research limitations/implications Use of qualitative sampling and analysis limits the generalizability of this paper. However, the quantitative representation of data demonstrates the strength with which motivations were perceived to influence consumption choice. Practical implications Ethical brands which focus on explicit altruistic ethical messaging at the expense of hedonistic messaging, or ambiguous pseudo ethics-as-quality messaging, limit their appeal to mainstream consumers. Retailers, however, benefit from the halo effect of ethical brands in store. Social implications The paper highlights the importance of retailer engagement with ethical products as a precursor to normalizing ethical consumption, and the importance of normative messaging in changing habits. Originality/value The paper provides original robust critique of the current field of ethical consumption and an insight into new theoretical themes of urgent general interest to the field.

Consumers are increasingly facing product evaluation and choice situations that include information about product sustainability, i.e., information about a product's relative environmental and social impact. In many cases, consumers have to make decisions that involve a trade-off between product sustainability and other valued product attributes. Similarly, product and marketing managers need to make decisions that reflect how consumers will respond to different trade-off scenarios. In the current research, we study consumer responses across two different possible trade-off scenarios: one in which consumers face a trade-off between product sustainability and hedonic value, and another in which they must trade-off between product sustainability and utilitarian value. Our results suggest that, overall, consumers are more likely to trade-off hedonic value (e.g., esthetics) for sustainability than to trade-off utilitarian value (e.g., functional performance) for sustainability. In Studies 1A and 1B, we presented participants with a product choice task and also measured their anticipatory emotions as they contemplated their options. The results suggest that given a trade-off, consumers are more likely to choose a sustainable product when they have to trade-off hedonic value than when they have to trade-off utilitarian value. Further, these studies provide some insight into the emotions underlying this effect. In Study 2, we use a different consumer response measure, relative purchase likelihood, and investigate the effect of trade-off type across categories that vary in the degree to which hedonic and utilitarian attributes are perceived to be important (referred to as 'product type'). Our results suggest that the effect of trade-off type still holds, yet is moderated by product type such that consumers' greater willingness to trade-off hedonic value (vs. utilitarian value) for sustainability is attenuated as the relative importance of hedonic (vs. utilitarian) attributes increases. In addition to building on our theoretical understanding of decision making given trade-offs with moral attributes, this research is also intended to support managers as they define and choose among various strategic, product development, and marketing promotion options.
