Segments of sustainable food consumers: a literature review

Sustainable food consumption is an important aspect of sustainable development. When adopting a sustainable food lifestyle, consumers are confronted with complex choices. Today's food consumption is too complex to be explained by socio‐demographic factors exclusively. A broader perspective is needed. In order to explain behaviour across different consumer segments better, relatively homogenous segments of food consumers were identified by segmenting food consumers based on a wide range of variables. The current study aims to provide an overview of published studies that have segmented consumers with regard to sustainable food consumption. The literature review has been conducted by searching SciVerse Scopus for all relevant articles available until November 2010. The main criterion for including a specific study was the inclusion of empirical analyses of primary data, resulting in consumer segments with regard to sustainable food consumption. Sixteen articles were incorporated in the final analysis. First, the variables used for segmentation and profiling in the included articles have been categorized into three levels of abstraction: personality characteristics, food‐related lifestyles and behaviour. The three levels of abstraction proved to be helpful in categorizing the segmentation studies. The findings indicate that variables on all three levels were efficient in differentiating consumer segments regarding sustainability. In addition, the importance of price and health differed across the segments, although these variables are only indirectly related to sustainability. Second, the three most frequently identified consumer segments with regard to sustainable food consumption were: ‘greens’, ‘potential greens’ and ‘non‐greens’. These segments differed from one another on all three levels of abstraction. This implies that future segmentation studies should include variables on all levels of abstraction to get a complete picture of existing sustainable consumer segments. Marketers should be aware that targeting specific segments based on socio‐demographic variables exclusively is not sufficient. Personality characteristics, lifestyle and behaviour are all important to take into consideration. Attempts at stimulating sustainable consumption might be most effective when differences across consumer segments are taken into account. Future research is needed to explore the characteristics of different sustainable food consumer segments with respect to their potential contributions in promoting sustainable development.     

Perceptions,attitudes, and behaviors toward sustainable fashion: Application of Q and Q‐R methodologies

While sustainability has increasingly attracted the attention of scholars and practitioners, consumer attitudes and behaviors toward sustainable consumption have not yet been elucidated. The decision‐making process around sustainable consumption involves diverse and complex considerations including some forms of compromise (tradeoff). In addition, sustainability is a broad and subjective concept, and is not a primary attribute of a product Impacting the choices of consumers. Therefore, it is necessary to apply new methods to overcome the limitations of conventional evidence‐based research. This research uses Q and Q‐R methodologies to identify consumers' subjective viewpoints toward sustainable fashion and to present socio‐demographic differences across segments of sustainable fashion consumers. Study 1 uses Q methodology to interview 26 consumers and to identify four types of decision makers: doubtful egoists, single‐minded bystanders, wavering intellects, and opinion leaders. Study 2 uses Q‐R methodology to verify the psychological and socio‐demographic variables among 328 consumers. The research provides useful suggestions for selecting and approaching target consumer segments in the sustainable fashion industry.     

Assessing the demand for value‐based organic meats in Canada: a combined retail and household scanner‐data approach

We apply sets of weekly retail and household scanner data to estimate consumer demand of selected organic and conventional fresh beef products in the Canadian retail market. The main contribution of our study stems from the application of a two‐stage procedure that provides new and deeper insight into consumers' responses to changing retail environment and pricing for organic and conventional meat products. Combined knowledge of point‐of‐sale consumer behaviour for value‐based products, such as organic products, and distinct socio‐demographic profiles of buyers vs. non‐buyers of meat is especially interesting for retail managers and meat industry stakeholders. First, household meat consumption patterns are investigated based on household scanner data that track household's meat purchases in the period 2006–2007. The second step of analysis then involves the estimation of an almost ideal demand system for selected organic and conventional fresh beef products using retail scanner data for the period 2000–2007. The introduction of greater selections in organic product lines across mainstream supermarkets in Canada in response to consumer health concerns is expected to spur retail competition in an otherwise saturated Canadian retail market. The analysis of socio‐demographic profiles in beef consumption using individual household's purchase data reveals that besides regional differences in preferences, household size and resource characteristics are major determinants of point‐of‐sale beef purchase decisions. Our demand system results indicate that organic beef is highly dependent on price and expenditures, whereas demand for conventional beef is mostly driven by income, habits and ‘typical’ Canadian seasonal beef consumption patterns. Altogether, our conclusions on organic beef vs. conventional beef buyers may have further implications for institutional regulations.     

Factors affecting consumers’ purchase intention of eco‐friendly food in China: The evidence from respondents in Beijing

The purpose aims to examine the key factors influencing Chinese consumer’s purchasing behaviour of eco‐friendly food in China giving its context as an emerging economy and its rapidly rising importance in the world eco‐friendly food market. This paper adopts and extends the Responsible Environmental Behaviour (REB) theory by empirically testing key psychosocial factors influencing the purchase intention of eco‐friendly food and the moderating effects of consumers’ demographic characteristics on the relationship between the key psychosocial factors and the purchase intention. A number of hypotheses are proposed. A questionnaire was designed and distributed via online survey in Beijing, China. A total of 239 valid responses were received. The empirical data were used to test the research hypotheses using the hierarchical multiple regression analysis. The research finds that the personality factors in the REB model (i.e., pro‐environmental attitudes, the internal locus of control and personal responsibly) have significant positive effects on the consumers’ eco‐friendly food purchase intention. Such effect is stable across consumers with different income levels. On the other hand, the knowledge–skill factors in the REB model do not have significant effect on the purchase intention of consumers. This study contributes to a better understanding of factors affecting eco‐friendly food consumption intention in China and the behavioural characteristics of consumers in developing countries. Moreover, the findings also shed light on the applicability of the REB theory in emerging economies and a specific industrial context.     

Ethical consumer behaviour in Germany: The attitude‐behaviour gap in the green apparel industry

In today's society, the trend of ethical consumerism is undeniable. Yet, even though consumers are ethically concerned, they rarely transform their intentions into a green purchasing behaviour—and this phenomenon is also evident in the sustainable fashion industry. This study aims to understand the prevailing attitude‐behaviour gap and explores the barriers that constrain consumers in purchasing green apparel. A total of 13 in‐depth interviews were conducted and analysed to the principles of grounded theory. The analysis reveals that the following barriers impede consumption of sustainable fashion: price, availability, knowledge, transparency, image, inertia and consumption habits. The impact of each dimension on consumers' purchase decisions might be of interest to apparel manufacturers and retailers who should implement strategies to encourage eco‐conscious apparel acquisition and focus on diminishing these barriers. Accordingly, three major recommendations are made: (a) to concentrate on specific product attributes; (b) to adopt an efficient digital communication strategy; and (c) to make a greater effort on making green apparel attainable. This study contributes to the overall understanding of consumer behaviour in the ethical fashion industry and examines in‐depth the purchasing criteria for sustainable fashion for consumers.     

Towards a Framework for Understanding Fairtrade Purchase Intention in the Mainstream Environment of Supermarkets

Despite growing interest in ethical consumer behaviour research, ambiguity remains regarding what motivates consumers to purchase ethical products. While researchers largely attribute the growth of ethical consumerism to an increase in ethical consumer concerns and motivations, widened distribution (mainstreaming) of ethical products, such as fairtrade, questions these assumptions. A model that integrates both individual and societal values into the theory of planned behaviour is presented and empirically tested to challenge the assumption that ethical consumption is driven by ethical considerations alone. Using data sourced from fairtrade shoppers across the UK, structural equation modelling suggests that fairtrade purchase intention is driven by both societal and self-interest values. This dual value pathway helps address conceptual limitations inherent in the underlying assumptions of existing ethical purchasing behaviour models and helps advance understanding of consumers’ motivation to purchase ethical products.     

Immigration and Chinese food preferences in the Greater Toronto Area

This paper presents important socio‐economic characteristics of Chinese Canadians in the Greater Toronto Area (GTA) and the impact of these characteristics and acculturation on their expenditure on and consumption of ethnic vegetables. These consumers purchase ethnic vegetables based on attributes such as quality, traceable production, versatility and language. The factors that predict expenditure on ethnic vegetables among Chinese Canadians are as follows: the percentage spent on food out of total monthly income, years spent in Canada and acculturation. The estimated demand per month for Chinese ethnic vegetables in the GTA is $CAD21 million. Meeting this demand with ever more locally produced vegetables will reduce ‘food miles’, enhance niche market production and facilitate greater agricultural sustainability in Ontario.     

Information search behaviour and its determinants: the case of ethical attributes of organic food

Daily decisions on food purchase are known to be undertaken using limited information search. However, when confronted with ‘ethical’ products, consumers often become more involved, and this results in a more extensive search for information. This research focuses on the information search behaviour of European consumers with regard to ethical attributes like animal welfare or environmental aspects of organic food by means of an Information Display Matrix. Row‐wise information search by product characteristics (attributes) was widely preferred over information search by product alternatives (column‐wise). Therefore, information (e.g. in the Internet) should increasingly be provided by attributes. The majority of consumers use simplifying and selective search strategies when looking for information on organic food with additional ethical attributes. Consumers tend to start information search in the top, left hand corner and move towards the bottom, right hand corner. Thus, principal attributes should be placed in the upper left corner and be followed by the next most important and so on when presenting information on an array of different products. Our results show that information search patterns of consumers depend on socio‐demographic characteristics like gender and age and, to a lesser extent, also on attitudes regarding environmental or social aspects of food production. Thus, marketers, particularly those using the Internet, should revise their systems of information provision and focus increasingly on consumers' needs.     

Social influence on sustainable consumption: evidence from a behavioural experiment

Although social influence on consumers’ behaviour has been recognized and documented, the vast majority of empirical consumer studies about sustainable products considers mainly, if not only, individual characteristics (socio‐demographic attributes, individual environmental attitudes, etc.), to explain the decision to buy sustainable products. Making use of experimental methods, this paper studies the social influence that peer groups like colleagues, family and friends may exert in the decision to choose for environmentally friendly products rather than conventional ones. We also test for different types of social influence, in particular for ‘herd behaviour’ vs. ‘social learning’. In our experimental setting, the relevance of peer effects is corroborated. We find clear evidence for ‘herd behaviour’ and the data indirectly support the presence of ‘social learning’ effects. The results also suggest heterogeneous impact of specific social groups.     

Consumers’ subjective and objective consumerism knowledge and subsequent complaint behaviour concerning consumer electronics: a South African perspective

Although there is immense international support for consumer protection, the notion exists that consumer protection can only exist in developed countries with ample fiscal resources and expertise to properly act in the interest of consumers. This conception leaves consumers in emerging and transitional economies in a difficult position as these economies indeed generally lack sufficient funding and the required capacity to educate consumers on their rights. With the South African Consumer Protection Act that came into effect in 2011, South African consumers can now claim to be among the best protected consumers in the world. However, many consumers are still not aware of their consumer rights, and do not have the necessary knowledge to pursue redress when they are dissatisfied. The objective of this research was therefore to explore and describe the relationship between consumers’ knowledge of consumerism (consumer protection) and their consumer complaint behaviour (CCB) concerning their dissatisfaction with a technologically advanced product, in this case, a consumer electronic product. This study attempts to differentiate between subjective consumerism knowledge and objective consumerism knowledge and by extension the measures used. In addition, we explored and described the relationship between demographic variables and levels of subjective and objective consumerism knowledge as well as the combined effect of the two types of knowledge on CCB. The findings revealed that the respondents had a reasonable level of subjective consumerism knowledge relative to a low level of objective consumerism knowledge. No significant relationship was found between subjective consumerism knowledge and demographic variables. However, the factors of race, gender and level of income were related to objective knowledge. A higher level of subjective knowledge could be associated with public action. Respondents with reasonable levels of objective knowledge were also better equipped to take private and public action. CHAID (Chi‐Square Automatic Interaction Detection) analysis highlighted that a combination of subjective and objective knowledge was the best predictor of taking public action only and of taking both private and public complaint action. The study has implications for policy makers, consumer protection organisations, retailers and the individual consumer. Our approach to measuring knowledge of consumerism could possibly be applied in other emerging contexts where consumers generally lack awareness of consumer protection.     

Does sustainability really matter to consumers? Assessing the importance of online shop and apparel product attributes

Although there is a shift in consumers' consumption behavior towards more sustainable patterns across a variety of different contexts, sustainable apparel has still not become a mainstream trend despite the textile industry's excessive usage of valuable resources. Albeit extant research found different potential barriers elucidating why consumers hesitate to purchase such apparel, it remains unclear whether sustainability really matters to consumers in a clothing context and further, which aspects are of relevance during consumers' purchase decision. We thus conducted two studies with four best-worst scaling experiments in which 4,350 online shoppers assessed the importance of both conventional and sustainable apparel attributes, as well as sustainable apparel attributes only, and the willingness to pay for sustainable product attributes. We further inquired the importance of conventional as well as sustainable online shop attributes. Our findings indicate that conventional apparel attributes such as fit and comfort, price-performance ratio, and quality are of higher relevance to consumers than sustainable attributes. The most important sustainable apparel attributes are the garment's durability, fair wages and working conditions, as well as an environmentally friendly production process. Consumers also indicated to prefer the latter three attributes to a 20% discount. Moreover, consumers demand less as well as sustainable packaging, free returns, and discount campaigns. Our findings reveal a gender gap regarding green consumerism with female respondents assessing most sustainable attributes as more important than male respondents do.     

Consumers’ everyday food choice strategies in Finland

In developed countries, choosing and purchasing food is today perhaps more complex than ever. In recent years, European consumers have experienced several food crises. We face a rapidly expanding range of novel food products, the food chain has become longer, and the origin of food more anonymous. At the same time, consumers confront increasing amounts of information on food every day. Consumers build their conceptions of modern food‐related risks on the basis of their everyday knowledge and coping strategies. Hence, the focus of this paper is on consumers’ food choices and everyday practices in relation to food safety and quality as well as food‐related risks. The paper is based on a Finnish study 1 examining consumers’ food choices. The data for the study were collected in September 2004 using an Internet‐based food diary accompanied by open‐ended questions on food‐related views and strategies. Altogether, 92 consumers completed the diary. The method combining the tradition of dietary intake and food consumption surveys with open‐ended questions was developed in order to gain an insight both on the types of foods purchased and on consumers’ conceptions of food‐related issues. In this paper, we focus on the key findings of the study as regards to consumers’ notions on food quality and safety issues and the practices they use in their everyday lives. We found eight everyday strategies consumers use. We suggest, first, that the strategies are important in simplifying food choice and making daily life easier, and second, that consumers use food‐related information flexibly in creating these strategies.     

Profiling consumers based on information use and trust in a developing economy

In the wake of the intense debate about the effect of poultry imports on domestic poultry industries in sub‐Saharan Africa, information campaigns have evolved to encourage the consumption of domestic poultry meat products. Nevertheless, consumers use numerous channels to find information, and thus, the extent to which resources should be allocated to these channels to reach segments of consumers is vital. The purpose of this paper is to identify consumer groups based on use and trust in information sources and then profile the segments using sociodemographic variables, purchase motives, and meat consumption. Face‐to‐face interviews were used to collect data amongst 500 urban consumers in Ghana, which were analysed with factor analysis and two‐step cluster analysis. Results show that consumers frequently use personal sources of information about chicken. Cluster analysis revealed three consumer segments: cautious consumers (18.2%), enthusiastic consumers (53.0%), and optimistic consumers (28.8%). The segments differed significantly regarding the type of information searched for, sociodemographic characteristics, purchase motives, and chicken meat consumption patterns. The findings can aid actors and institutions seeking to increase the consumption of domestic poultry meat in developing targeted communication strategies that suit the characteristics, motivations, and information needs of different consumers.     

Understanding consumption behaviours for fair trade non‐food products: focusing on self‐transcendence and openness to change values

Using the Schwartz value system, this study explored the personal values of consumers related to fair trade product consumption. This study further investigated how the values determine beliefs, attitudes and purchase intentions associated with fair trade non‐food products. Data were collected using an online survey from a random sample of 1824 nationwide consumers. The results of this study revealed that fair trade purchasers show a higher level of self‐transcendence (universalism, benevolence) and openness to change values (self‐direction, stimulation) than non‐purchasers. These values also have positive effects on the formation of beliefs, attitudes and purchase intentions pertaining to fair trade non‐food products. Fair trade purchasers were also found to possess distinctive socio‐demographic characteristics concerning age, education and income. Findings can offer marketers specific information regarding consumers' motivations to purchase fair trade goods, which can improve targeting of products and ultimately increase the business and benefits of fair trade.     

An analysis of child consumers in Turkey

This research was conducted on 402 children going to kindergarten and primary schools with the purpose of analysing the children's interests, responsibilities, economic resources, purchasing activities, and socialization agents and purchase influences as consumers. Data were collected using a questionnaire, which was prepared by considering some previous research. The questionnaire was applied to subjects through face‐to‐face individual interview. The data were analysed by using explanatory variables, including age, gender, socio‐economic status and family type. Findings indicated that consumer socialization of children was connected to selected demographic characteristics, especially age, and they were surprisingly independent and influential consumers. The results of this study are important for those involved in children's and adults’ markets, and for consumer educators.     

An examination of the values that motivate socially conscious and frugal consumer behaviours

This article extends social psychological research on the motivations for sustainable consumption from the predominant domain of ecologically conscious consumer behaviour to socially conscious and frugal consumer behaviours. A UK‐based survey study examines relationships between socially conscious and frugal consumer behaviours and Schwartz's value types, personal and socio‐political materialism, and demographics among the general public. Socially conscious consumer behaviour, like its ecological counterpart, appears to be an expression of pro‐social values. In contrast, frugal consumer behaviour relates primarily to low personal materialism and income constraints. As such, it does not yet represent a fully developed moral challenge to consumerism.     

Applying the Institutional Theory at the Level of Halal Consumers: The Case of Cape Town in South Africa

The institutional theory, especially at an individual level, has not been conducted on halal consumers in South Africa. The purpose of this study was to evaluate the degree to which halal consumers who have higher institutional pressures are more expected to purchase halal food products. This study draws upon institutional theory to present empirical evidence that institutional factors may show a significant effect on halal consumer’s purchase intention and buying behavior toward purchasing halal food products. A sample of 298 halal consumers in South Africa was selected. Data samples were collected via self-administrated questionnaires. Structural equation modeling (SEM) was used to test study hypotheses. The study showed that all institutional factors have a direct effect on halal consumer’s intention and indirect effect on buying behavior. Based on the results, normative pressures had a high significant effect among institutional pressures, followed by other factors such as mimetic and coercive pressures, respectively. This study is first of the uncommon studies examining halal consumers’ purchase intention and buying behavior in a non-Muslim country, employing the institutional theory in the context of halal food consumption.     

Exploring the relationship between consumer knowledge and purchase behaviour of value‐based labels

Despite an increasing market presence, little research has been conducted regarding consumer‐purchase behaviour of food products bearing ‘value‐based’ labels. Moreover, as the effectiveness of these labelling formats is dependent upon consumer's knowledge of their existence, this paper aims to explore the relationship between knowledge, openness to experience (i.e. validated personality trait related to intellectual capability) and purchase behaviour upon consumer behaviour in this context. Using structural equation modelling techniques, causal influences on purchases of fresh meat bearing ‘value‐based’ labels are identified and three multi‐attribute attitude models are proposed. The paper concludes that these labels are of value to consumers and that product knowledge plays a significant role in aiding purchase decisions. Consequently, marketing communication implications arising from the proposed multi‐attribute attitude models are discussed.     

Attitudes and consumption values of consumers of imported fruit in Guangzhou,China

Research on how Chinese consumption values influence Chinese consumer behaviour is rare. First, this paper examines consumers’ attitudes towards the physical and intangible attributes of imported fruit. Then, it identifies consumers’ consumption values and the role of these values in purchasing behaviour. Data were collected through point of sale intercept surveys conducted in Guangzhou, China. Latent consumption values of consumers were identified through factor analysis. K‐means clustering revealed four natural groupings of consumers, each group demonstrating different consumption values. The results demonstrated the primary importance of symbolic values and hedonic values in the decision to purchase imported fruit. Such consumption values may derive from the intermingling of Confucian and Western cultural values. Results from this study could help to better understand interrelationships among product attributes, consumption values and cultural values, and could make a significant contribution in developing strategies to market imported fruit in China.
