Sustainability labeling has been increasingly integrated into many food product labels in response to consumer interest in purchasing sustainably produced food. While a product label may contain the phrase "sustainably produced", little additional information is available to consumers regarding how sustainability has been enhanced, or the dimensions of sustainability encompassed by the label. Using data from a survey of 1416 Canadian consumers, we examine consumer perceptions of sustainability and preferences for broad versus narrow sustainability claims across several contexts, including the dimensions of sustainability and the scope of a sustainability standard with respect to compliance criteria, product coverage, and geographical coverage. We find low levels of consumer knowledge and understanding of sustainability labeling, heterogeneity with respect to which dimension of sustainability appeals to different types of consumers, and a general preference for broad over narrowly defined sustainability labels, particularly with respect to the scope of criteria encompassed by the label. Our findings suggest some confusion as to what constitutes sustainability in the context of agri‐food, but that broader, more encompassing labels are likely to gain more traction with consumers.

Purpose: The authors mobilise stewardship theory, which delves into trust and collaboration dynamics, advocating for long-term gains through actions beneficial to the broader community. Used as a fundamental framework to conceptualise the model, stewardship theory enhances the understanding of the effect of purchasing social responsibility (PSR) practices to foster innovativeness and performance through the supply chain (SC). This study aims to examine the relationship between PSR, SC innovativeness (SC-INNO) and SC operational performance (SCOP). In addition, the moderating effect of sustainability labels on these relationships will be studied. Design/methodology/approach: Based on survey data from 177 organisations analysed through partial least square structural equation modelling, the results suggest that PSR has a positive and significant effect on SC-INNO and SCOP. In addition, SC-INNO plays a partial mediation role since the direct effect between PSR and SCOP is validated. Furthermore, the moderating effects of holding a sustainability label and industry type about PSR and SCOP are supported. Findings: The results indicate a significant positive influence of PSR on both SC-INNO and operational performance. SC-INNO is found to partially mediate the PSR–SCOP relationship. Moreover, sustainability labels and industry type significantly moderate the effects of PSR on SCOP. Originality/value: The findings extend stewardship theory into the sustainable purchasing and supply management field by providing empirical support for PSR as a reflection of stewardship behaviours by fostering innovation and performance throughout the SC.

We use the entropy balancing method to study the impact of sustainability labels on mutual fund flows and returns. We compare the informativeness of the ESG risk metrics developed by a specialized agency – the Morningstar sustainability rating – with the ESG disclosure requirements introduced in the European Union by the Sustainable Finance Disclosure Regulation. We find investors to follow the Morningstar's ESG ratings to inform their portfolio decisions, with more sustainable funds attracting larger net inflows. On the contrary, regulation-induced labels are generally not relevant to explain flow heterogeneity, with the only exception of Article 9 funds in which sustainable goals are the core investment objective; these latter funds also outperform their peers in terms of returns in line with ESG preferences strengthening over time.

This study investigates the effectiveness of sustainability labels, environmental attitudes, food safety concerns, and knowledge on Vietnamese consumer preferences for sustainably farmed shrimp. Mixed logit and latent class models were applied to estimate utility functions based on 459 samples collected using a choice experiment. The results indicate that Vietnamese consumers prefer sustainably farmed shrimp to conventionally farmed shrimp. Also, both food safety concerns and consumer knowledge vigorously promote sustainably farmed shrimp choices. Notably, the latent class results show that 73.5% of the respondents consider their environmental concerns about shrimp production when making decisions about consumption. The results indicate that placing information related to eco-friendly and food safety attributes on sustainability labels provides Vietnamese consumers with additional choices in the form of sustainably farmed shrimp. Finally, the simulated MXL results in the WTP space are more significant than those in the preference space, indicating that it is necessary to estimate the MXL in the WTP space to avoid specifying the parameter distribution subjectively by analysts.

A system that enables businesses to quantify the environmental impacts of products, contextualise this data with scientifically determined limits (planetary boundaries), and communicate it with buyers in a way that is easy to understand has the potential to drive significant pro-environmental decision making and outcomes. An immense proportion of global decisions occur through a product lens. There is evidence of both business and purchaser demand for a system that supports easy-to-understand environmental data about products with scientific context. Governments and policymakers have a pivotal role to play in the successful implementation of such a system. [ABSTRACT FROM AUTHOR]

Amidst growing emphasis on sustainability in the hotel industry, hotels are increasingly adopting sustainable practices. This trend extends to online platforms, where hotels showcase their sustainability labels as a form of advanced Corporate Social Responsibility (CSR). Such CSR communication is crucially influenced by how customers perceive the consistency of a hotel's CSR efforts. In the sphere of online hotel booking, customer reviews play a pivotal role as other external clues, illustrating how well hotels fulfill their fundamental economic responsibility. Our study aims to investigate the interactive effects between hotel sustainability labels and the valence of online reviews on customers' booking intentions. Based on attribution theory and several experimental studies, this research reveals that in the context of negative hotel review valence, the presence (vs. absence) of sustainability labels decreases customers' booking intention due to an increase in perceived hypocrisy towards the hotel; conversely, in the context of positive hotel review valence, the presence (vs. absence) of sustainability labels enhances customers' booking intention due to an increase in perceived morality towards the hotel. These findings contribute to the literature exploring hotel sustainability labels, online hotel reviews, and perceptions of hotel hypocrisy. ● Hotel managers should balance sustainability labels with online review management. ● The label-review mismatch heightens customers' perceived hypocrisy towards hotels. ● This label-review mismatch reduces customers' booking intentions towards hotels.

A transition toward a sustainable way of living is more pressing than ever. One link to achieving this transition is to increase the currently low level of sustainable consumption, and sustainability labeling has been shown to directly influence sustainable purchasing decisions. E-commerce retailers have recently picked up on a means to inform online shoppers about sustainable alternatives by introducing on their websites third-party and private sustainability labels as nudging instruments. However, despite its increasing relevance in practice, research lacks evidence about the availability and credibility of sustainability labeling in online retail. Our study is guided by the question of how online retailers use sustainability labels to communicate information on the sustainability of products to consumers. Our empirical research is based on a large-scale dataset containing sustainability information of nearly 17,000 fashion products of the leading online retailers in Germany Zalando and Otto. The results show that a large number of fashion products are tagged as sustainable, with two-thirds carrying a private label and one-third a third-party verified label. Only 14% of the tagged products, however, present credible third-party verified sustainability labels. This low percentage makes it challenging for consumers to comprehend to what degree a product is sustainable. The wide distribution of private labels indicates that most of the available sustainability information in the selected online shops addresses only single sustainability issues, preventing comparability. Furthermore, label heterogeneity can add to the confusion and uncertainty among consumers. Our practical recommendations support political initiatives that tackle the risk of greenwashing resulting from uncertified and weak sustainability information.

In the last few decades, the interest of consumers towards sustainable agri-food products has been growing. This trend reflects changes in the consumption patterns, which have been deeply influenced by the increased sensitivity concerning social and environmental issues. In this sense, several studies, with different methodological approaches, have investigated consumers' willingness to pay and its determinants for products with different sustainability labels. To systematise the obtained results, this paper offers a review of the studies that used experimental economics in studying consumer preferences for sustainable food and agricultural products. The 41 studies included in the review were selected on the basis of the pre-identified criterion according to the systematic review approach. Albeit discordant, the results show that a large share of consumers is willing to pay a premium price for products with eco-friendly and organic certifications. Animal welfare, 'local' production, or social certification appear to have a lower influence on consumer choice of purchasing. Additional information is able to modify consumer expectations and consequentially their willingness to pay, depending on the individual's responsibility and awareness.

This study investigated whether endorsement of personal values is associated with willingness to pay more for mobile phones with an environmental or social sustainability label. Participants were students in Sweden, Norway and Germany. A self-report inventory was used to measure willingness to pay and the importance attached to values of Schwartz's circular model. In Sweden and Norway, participants were willing to pay, on average, 18% extra for a mobile phone with labels for environmental or social sustainability. In Germany, the corresponding share was 12%. To strive for self-enhancement values, that is, social status and prestige, as well as control and dominance over people and resources, was associated with a lower willingness to pay for mobile phones with labels for environmental or social sustainability in all three countries. Furthermore, women were willing to pay more than men for mobile phones with both kinds of sustainability labels. In Sweden and Norway, participants were, on average, willing to pay more for a mobile phone with a label for social sustainability compared to a mobile phone with a label for environmental sustainability.

Previous research on sustainability and health-related product labels has sought to develop segmentation frameworks based on consumers' self-reports. However, consumers are likely to overstate the effect that these labels have on their purchasing behavior. Moreover, existing consumer segmentation frameworks do not distinguish among product labels based on whether they offer public benefits (e.g., environmental benefits, animal welfare, social equity) vs. private benefits (e.g., cost savings, health benefits) vs. both. This article addresses these gap by 1) developing a consumer segmentation based on consumers' actual purchases of sustainability and health-related products and 2) differentiating product labels based on the benefits they offer – public, private or both. Using cluster analysis, it assesses the actual daily consumption of 132 Italian consumers over 30 months and more than 370,000 transactions. The results indicate three segments of consumers: collectivists, individualists and indifferents. Moreover, the findings show that consumer segments are affected differently depending on whether a product label promises either public benefits, private benefits or both. [ABSTRACT FROM AUTHOR]

By conducting a laboratory experiment, we investigate how consumers' purchasing behavior for certified forest coffee is affected by consumers' interest in environmental issues, the provision of information, and product labels. We contribute to the literature in the following three ways. First, we conduct a randomized controlled trial (RCT) to control biases due to endogeneity. Second, we utilize eye-trackers to examine how different product labels result in different visual attention. The combination of an RCT and eye-tracking techniques is new in the literature on purchasing behavior for environmentally friendly products. Third, our experiment measures participants' purchasing behavior that incurs actual costs rather than examining their willingness-to-pay (WTP) based on hypothetical questions. We find that concerns regarding environmental issues do not promote purchases of certified forest coffee. Information about certification programs does not have any effect on purchasing certified forest coffee unless information is provided to prior purchasers of certified forest coffee. By contrast, illustrations of forests on certified forest coffee labels attract participants' visual attention and further stimulate actual purchases of certified forest coffee, suggesting that a 1-second increase in visual attention increases the likelihood of purchasing certified forest coffee by 22 percentage points.

Legumes are valued in agricultural systems, as they can contribute to a more sustainable land use. However, their economic value is low. Despite health and environmental benefits, marketers struggle to communicate the worth of legumes to consumers. We evaluate the worth of health and, in particular, environmental claims that would spread consumers' awareness of ecological advantages. Utilizing a large consumer sample, we execute binding online auctions. Comparing claim-treated and untreated subjects (between design), we model the price premium that potential customers are willing to pay (WTP) for having pasta in a legume instead of a wheat version. We find that claims may increase the WTP, however, a mix of environmental and health claims is superior to individual claims. Effect sizes suggest that the mix of claims increases the WTP by roughly 35% (20 cents). The link of WTP and food attitudes, such as concern for health in eating habits or social reservations towards legumes, varies depending on whether the green-pea or chickpea pasta was evaluated. A critical perception of legumes' association with flatulence reduces the WTP. Developing the online auction may enable researchers to increase the external validity of consumer samples. We discuss implications for researchers and marketers. [ABSTRACT FROM AUTHOR]

• Too many sustainability labelling schemes on food products get consumers confused. • Rather than reassuring, sustainable labels may themselves lead to consumer distrust. • In this study, scepticism played multiple roles in the food purchasing process. • Scepticism influenced buying behaviour and its relationships with other antecedents. • Marketers should provide more robust evidence for all sustainability claims. This paper aimed to investigate consumer scepticism towards third-party sustainability labels in the context of food products, evaluating its role in the formation of the customer's buying behaviour. A covariance-based structural equation model (CB-SEM) was developed, and it included the customer's socio-environmental concern, scepticism toward sustainability labels, reported use of the socio-environmental commitment declared by the producer, and purchase behaviour of sustainably-labelled food products. The model was tested on a sample of 311 Italian high-educated young consumers, a group of sustainability-conscious individuals. The findings highlight that purchase behaviour is positively influenced by two reciprocally-related variables: socio-environmental concern and the reported use of the socio-environmental commitment declared by the producer. While other studies have ascertained that scepticism is an antecedent of purchase behaviour, this study findings highlight it can also be considered a mediator of the relationships between purchase behaviour and other antecedents considered in this model. In addition to advancing the study on the role of scepticism in the formation of purchasing decisions for food products, drawing on signalling theory, this study provides insights for practitioners and policymakers, highlighting the absolute necessity to reassure consumers about the credibility of third-party sustainability labels and providing them with the instruments needed to distinguish the truth from the fluff in sustainability communication.

Sustainability labels are important tools that help consumers assess the sustainability aspects of food. While past studies have focused on visual attention to nutrition information, no study has investigated the visual attention paid by consumers to the sustainability information on food. Our study contributes to the need to better understand consumers' attention to sustainability information when making food choices. The objective was to explore the importance that consumers attach to sustainability attributes and investigate how this relates to the visual attention paid to these attributes during the choice decision and to willingness-to-pay (WTP). Visual attention during the decision making process was measured in terms of fixation time and fixation count, which were then analyzed in relation to the stated attribute importance. Our results suggest that consumer segments with differences in stated attribute importance, visually attend differently to these attributes. Higher valued attributes also exhibited higher visual attention. Our results suggest that consumers who spend more time attending to and fixate more on sustainability attributes value them more.

This study evaluates young consumers' attitudes to sustainable food and analyzes the determinants of their willingness to pay (WTP) for chocolate bars with different sustainability labels. Data were collected through experimental auctions in Italy assessing respondents' ( N = 80, aged between 18 and 35) WTP for chocolate bars with three selected labels (i.e. Fair Trade, Rainforest Alliance and Carbon Footprint). Econometric outcomes reveal that several socio-demographic factors exert a positive and statistically significant effect on WTP for all the selected chocolate bars, namely age cohort (older), gender (female) and household income (high). Respondents' lifestyles and food consumption habits also had an effect on final bids. This study offers valuable insights to policy makers and practitioners for efficiently targeting young consumers in campaigns to increase sustainability-labelled food consumption.

We investigate the effect of information provision about environmentally friendly coffee on consumers' purchasing behaviors. We use a dataset from a nationwide social experiment in Japan involving over 10,000 vending machines serving brewed coffee. We also provide empirical insights into the potential drivers affecting pro-environmental behavior of consumers through information provision. Our results demonstrate that informing consumers about the product's eco-friendliness significantly increases eco-friendly coffee sales (+7%) only in social spaces (e.g., office buildings) and not in non-social spaces (e.g., shopping malls). Consumers in social spaces might be motivated to purchase eco-friendly coffee to build a "green" reputation among community members after receiving such information. • Information provision about eco-friendly coffee does not stimulate sales in general. • Verbal information provision method increases sales by 7% only in social spaces. • The impact of visual information provision method was insignificant.

Food labels allow producers to promote the unique selling points of their products and help consumers buy products with value-adding qualities. The aim of the present article is hence to explore Czech food producers' expectations and experience with selected food labels. The selection was narrowed down to enterprises that had succeeded in the certification processes within the food labeling systems of European quality and origin labels (protected designation of origin (PDO), protected geographical indication (PGI), and traditional specialty guaranteed (TSG)), as well as schemes that fall under the remit of the Ministry of Agriculture of the Czech Republic, such as Klasa (Česká potravina/Czech food, Regionální potravina/regional food, and BIO). The research was made using an online questionnaire in January–February 2018, and was focused on determining possible discrepancies in expectations that the companies had before applying for quality/origin labels and their actual experience with the labelling systems, the benefits they had gained, and their overall experience with the labels. To compare the respondents' expectations and their actual experience, both the non-parametric Wilcoxon test and t-test were used. The results show that the respondents positively evaluated the effects of marketing communication, but their expectations had been higher than what they experienced. [ABSTRACT FROM AUTHOR]

Sustainable labelling is an important tool in raising awareness and informing potential buyers regarding environmental, economic and social issues. This study provides insights into consumers' value of food sustainability labels through the exploration of the impact of logos on their purchasing decisions (willingness to buy (WTB)) and readiness to pay (willingness to pay (WTP)) a higher price for sustainability-labelled products. Data was collected via an online survey among a sample of 423 adult city dwellers in Poland. The structured questionnaire beside sections concerning consumer buying behaviour and perception of the food labels consisted of a behavioural choice experiment (CE), where two categories of plant products: fresh (apples or bananas) and non-perishable (rice or beans) varied by type of labelling (logos: Euro-leaf, PGI, Fair Trade or without logo) and by price. Cluster analysis revealed two consumer groups (named "Sceptical" and "Mindful") that had varied opinions and perceptions of sustainable labelled food and buying behaviour. The research results indicate that when the logo is poorly-known even consumers with positive attitudes towards sustainability do not use it as a cue when shopping for food. Moreover, urban consumers were very price sensitive and showed a restrained desire to pay a higher price for sustainability labelled products. [ABSTRACT FROM AUTHOR]

The study investigated preferences of consumers of food retailing outlets in Germany for sustainability labeled cut roses. A sample of 1201 respondents of an online survey was used to analyze their preferences based on a choice-based conjoint experiment in which a bunch of 10 roses was considered which differed concerning the labeling certificate, country of production of the plants, price, packaging, smell, and blossom size of the roses. Latent class analysis revealed existence of consumer heterogeneity with around two thirds of the respondents being strongly in favor of sustainability labels. Thereby Fairtrade labeled roses got an overall positive assessment whereby organic roses were only preferred by 31% of the respondents. In addition, paper or no packaging, strong smell and uniform big blossom sizes got overall positive consumer evaluations in the experiment. The study concludes that sustainability labeled plants might be an option for producers to append additional value to horticultural products in Germany. [ABSTRACT FROM AUTHOR]

Sustainability certification labels have become an important tool for aiding consumers in evaluating food safety, health concerns, and environmental friendliness. Few studies have explored the attributes of consumers' environmental consciousnesses from the perspective of environmental concerns; hence, we focus on that lack. Our study contributes to the need to better understand consumer attention to sustainability information when making coffee certification attribute choices. We aimed to explore the importance that consumers attach to coffee certification attributes paid to these attributes while choosing and to willingness to pay (WTP). There were 650 questionnaires completed by those who had purchased coffee beans habitually in Taiwan; after factoring out the invalid questionnaires (i.e., those with omitted answers, incomplete answers, or those in which answers to all the questions received the same scale points were all deemed as invalid and removed), 568 valid ones were collected with a recovery rate of 87.4%. The results indicate that the respondents' WTP attributes ranked from highest to lowest are traceability, organic, graded, environmentally friendly, and fair-trade certifications. This study provides insights into how consumers' preferences relate to selection of coffee certification attributes. [ABSTRACT FROM AUTHOR]
