The purpose of this study is to assist brand and product managers in selecting appropriate ingredient names for environmentally friendly products. It investigates the effects of unfamiliar ingredients on consumers’ evaluations of environmental friendliness and their purchase intentions, based on the cue consistency theory.

Five experimental studies (n = 968) were conducted to achieve the research objectives. Study 1 found that consumers tended to avoid choosing unfamiliar ingredients. Study 2 examined the impact of ingredient familiarity on consumers’ perceived greenness. Study 3 investigated the mediating role of perceived naturalness. Studies 4 and 5, respectively, explored the moderating effects of emphasizing the importance of technology in environmental conservation and product category.

The findings indicate that when environmentally friendly products are labeled with unfamiliar ingredients (vs. familiar), consumers’ perceived greenness and purchase intentions decrease. This effect is mediated by perceived naturalness. Moreover, the negative impact of unfamiliar ingredients is mitigated by emphasizing the importance of technology and the high-tech product category.

This paper reveals the unique role of unfamiliar ingredients in shaping consumer attitudes toward environmentally friendly products. Based on cue consistency theory, it uncovers how unfamiliar ingredients influence the perceived greenness of environmentally friendly products through perceived naturalness. Furthermore, the paper demonstrates the impact of emphasizing the importance of technology (emphasis vs. control) and product category (high-tech vs. low-tech) on consumer attitudes and behaviors toward environmentally friendly products.

As sustainability efforts have increased across the apparel and textile industries, consumers are being exposed to an increasing variety of information and label claims. The purpose of this paper is to determine consumer willingness to pay (WTP) for locally produced animal fiber products with organic and alternative labeling schemes, which included eco‐friendly, natural and sustainable.

Experimental auctions were used to elicit bids on wool socks from consumers across three Southern US states. Means were computed for the various bids, as well as bid differences before and after definitions. To test for significance, non‐parametric Wilcoxon signed‐rank tests for matched pairs were performed for all differences investigated.

Consumers indicated higher WTP for all versions over conventional wool socks, with the highest WTP exhibited for organic. WTP for organic versions further increased after definitions were provided. Natural and eco‐friendly versions had larger premiums than sustainable, but this difference disappeared after definition.

The experimental setting brings the results closer to actual consumer behavior, but eliminated many additional variables that consumers consider.

The results of this paper indicate that policy makers should consider definitions and certification for claims besides organic to potentially benefit wool producers.

This research provides consumer WTP comparisons for a variety of labeling terms currently appearing on wool apparel products. Uncovering this information provides greater understanding of consumer WTP for wool with such attributes, especially after definitions are presented.

The paper examined the impact of corporate communication about eco-friendly products on social media (CSM) and conventional media (CCM) on individuals/buyers’ intent for co-creating environmental values (ICEV) post-Coronavirus pandemic in Indonesia.

Data were gathered from 561 individuals/buyers, via cross-sectional sampling in Bandung city, Indonesia. Next, this study used structural equation modelling to assess the theoretical model and hypothetical relationships.

Both factors, i.e. CCM and CSM, positively and significantly affect ICEV.

The paper is an original attempt to assess the impact of corporate communication about eco-friendly products on media toward ICEV in Indonesia’s post-Coronavirus pandemic. Besides, it is an initial effort to create the notions of success expectancy and self-efficacy and analyse whether these two concepts can become factors that mediate the effects of corporate CCM and CSM on buyers’ ICEV. This paper also develops ICEV to expand social cognitive theory from the perspective of co-creating environmental values.

Would a green color label increase the dollar amount consumers are willing to pay for a green product? Would nature images (such as a leaf or flower) on the label have the same effect? This paper aims to examine the role of these labeling strategies in influencing consumer willing to pay.

Using a 2 × 3 experiment, the authors empirically test the research questions across two studies: in the controlled-lab setting with 160 students (Study 1) and in a field-setting with 268 consumers shopping at a grocery store (Study 2).

Results are consistent across both studies. Surprisingly, participants are willing to pay more for the product when it has a white-toned label rather than a green-toned one. Follow-up path analysis, with Study 2 data, reveals that a white-toned label has both an indirect (through more favorable evaluations of the product’s environmental friendliness), as well as a direct impact on willingness to pay. In providing a post hoc explanation, it is argued that a white-toned label better directs attention towards the claim signaling the product’s eco-friendliness, while providing a “clean”, “high-quality” look. In both studies however, nature images on the label did not have a significant effect.

Insights are particularly interesting for practitioners seeking to better label/package green products.

This investigation is the first to empirically examine how color and images on the label influence the dollar amount consumers are willing to pay for a green product. Findings reveal that counter to common belief, the heavy use of the color green on eco-friendly product labels might not be appropriate; a predominantly white-toned label works better.

This study aims to critically review the research on food eco-labels to identify research gaps and recommend future research directions in business and management.

A hybrid integrated review combines bibliometric analysis with an in-depth framework-based study of theory–context–characteristics–methodology (TCCM) and reviews quality research published over 21 years between 2002 and 2022.

We identify key research themes and the knowledge structure of food eco-label research. Future researchers should explore food eco-label dynamics and phenomena in areas related to consumer behaviour, information, consumer knowledge, environmental concerns, trust, packaging and willingness-to-pay as antecedent factors.

This review contributes to the business and management literature by quantifying existing research and consolidating its evolution. The articles were sourced from the established Web of Science (WoS) database. Other databases should be included in future reviews. We also focus on research published in business and management. Further studies could include research beyond such specialised domains.

Consumers need more information on the objectives and meaning of food eco-labels. The dissemination of knowledge on eco-labels, as well as effective communication and information on eco-labels, are relevant to future research issues.

The knowledge derived from this research holds significant potential in shaping policies and devising tools aimed at reducing the carbon footprint linked to food production and consumption. Considering the substantial impact of these activities on our planet’s carbon footprint, addressing food security and sustainability emerges as a crucial concern for humanity. Recognising the importance of eco-label communication and information becomes particularly pertinent for future generations, who stand to bear the most substantial impact of climate change and sustainable development. These generations are also more inclined toward embracing and implementing sustainable practices.

There are no comprehensive, integrated reviews exploring the methods, variables and constructs used in studies on food eco-labels based on all articles published in WoS journals in the business and management domains. This is the first comprehensive literature review using a hybrid approach (bibliometric review with TCCM framework) in the field of food eco-label research.

The problem of environmental pollution is becoming increasingly severe, and international consensus confirms the need for eco-friendly consumption. Worldwide, the eco-friendly food market is booming, so understanding consumers’ motivations to purchase these foods is crucial. This paper aimed to construct a model explaining consumers’ intentions to purchase eco-friendly food by combining stimuli-organism-response (SOR) and signalling theories and exploring the mechanisms by which macro- and micro-signals impact perceptions of value and consumers’ subsequent willingness to purchase eco-friendly food.

An online questionnaire was distributed through the Qualtrics platform, and the completed questionnaires were collected in March and April 2023. The study used partial least squares structural equation modelling (PLS-SEM) to analyse the 331 valid responses received.

The results indicated that trustworthy eco-labels for high-quality and health-promoting products, as conveyed in macro signals, significantly enhanced consumers’ perceptions of functional value. The peer effect and a moderate level of food anthropomorphism conveyed in micro-signals substantially improved their perceptions of social value, whilst the perceived value of products significantly and positively influenced their purchase intentions.

This study explains consumers’ motivations to purchase eco-friendly products. This provides an explanation for the effect of macro- and micro-signals on value perceptions. By integrating the different dimensions of these signals to create a unified research perspective, the paper provides an integrated model, thereby filling a research gap concerning the influence of two-dimensional signals on purchase intention. By supporting eco-friendly food use, the paper contributes to environmental protection and sustainable development.

This study aims to examine millennial consumers’ intentions towards purchasing eco-friendly products in the emerging Arab nation of Oman, focusing on the moderating role of eco-labelling (EL).

Environmental knowledge (EK) and environmental concern (EC) are integrated into the theory of planned behaviour (TPB) framework as independent variables, along with EL as a moderating variable. The data was collected through a self-administered survey and consisted of 705 random responses that was tabulated and analysed through the structural equation modelling technique.

ECs, subjective norms (SNs) and perceived behavioural control (PBC) significantly influence consumer attitudes towards green eco-friendly products. Consumers’ EK and attitudes positively influence the purchase intention (PI) to make green purchases. SNs and PBC substantially influence consumer attitudes towards adopting green products. However, the findings reveal a non-significant moderating influence of EL on the relationship between EC and PI for millennial Omani consumers.

The findings are limited to only one Arab country, Oman, which limits the scope of the study. This study contributes to the TPB by using additional dimensions to examine the green purchasing behaviour of millennials.

Marketers can use these insights to develop strategies that emphasise the environmental benefits of products, leverage social influences and empower consumers to make environmentally conscious choices. Incorporating EL and green packaging can enhance the visibility and attractiveness of green products.

Promoting environmental education, awareness campaigns and policy interventions that highlight the importance of eco-friendly product choices can foster more sustainable consumption patterns among Arab consumers.

To the best of the authors’ knowledge, this is the first study to examine the green PIs of millennials in an Arab context, specifically focusing on the moderating role of EL.

This study aims to gain a first explorative view on what intrinsic/extrinsic attributes a generic cup for hot beverage should possess to be perceived as eco-friendly, and how some attributes of a hot beverage could influence consumers’ purchase decision and willingness to pay (WTP) for that beverage dispensed by vending machines (VMs).

A questionnaire was developed in 2021 and sent to all students of an Italian university campus. For the first goal, students were asked to assign a score to some eco-friendly intrinsic/extrinsic attributes using a five-point Likert scale. For the second aim, a choice experiment with six scenarios was developed.

Both intrinsic and extrinsic attributes play a key role in shaping students’ opinions and preferences. Results indicate that students are attracted by the idea of a cup that communicates its environmental properties through corresponding labels and information, and it is made by materials that guarantee biodegradability, recyclability or reusability.

The research represents the first academic attempt to provide a first consumers’ viewpoint on the importance of eco-friendly attributes of cups for hot beverages able to influence consumers’ perceptions and consumption choices of hot beverages dispensed by VMs.

The purpose of this paper is to identify the realistic trade-offs young consumers make when purchasing organic T-shirts.

A full profile discrete choice design was used. The data were analysed using a multinomial logit model and desirability indices.

Price was the most important attribute to consumers followed by the place of production and then sustainability. Consumers were most willing to purchase T-shirts that are eco-friendly, Made In America, made from wrinkle-free technology and cotton jersey knit fabric, and have a price of $15. Although consumers were most willing to pay $15, some were still willing to pay $25 or even $35 for the same eco-friendly T-shirt.

Consumers in the current study were more willing to purchase eco-friendly as opposed to organic apparel. The findings suggest that retailers need to consider the language used when communicating with consumers. Also, consumers were more willing to purchase T-shirts Made In America. Retailers may want to promote their domestic manufacturing through in-depth branding and promotions.

In order to identify the attributes to be used in the current study, labels on T-shirts in stores were examined and then those attributes were verified in the literature. In addition, the inclusion of price as an attribute, rather than as a separate independent question, provides a more realistic view of young consumers’ decision making.

Environmental concern is getting increasing importance in consumer shopping decisions. Nevertheless, to date, sustainable packaged foods are not always the first option when consumers go shopping. This paper analyses how environmental concern moderates the role played by external factors – preference towards sustainable retailers and trust in sustainable producers – in determining consumer purchase intentions for sustainable packaged foods. Consumer involvement in eco-friendly labels, increasingly present in food packages, is investigated as indirectly impacting pro-environmental purchase intentions.

An online survey administered to a sample of Italian food shoppers is used for the empirical analysis. A total of 278 structured questionnaires were modelled using a structural equation modelling approach.

Findings show that producers and retailers' policies in favour of sustainability are key in determining consumers' sustainable purchase intentions. Further, coherent uses of labels and logos in light of sustainability can support consumer purchase decisions. Relevant is the influence played by the environmental concern in both supporting pro-environmental purchase intentions and in amplifying the trust in sustainable producers-purchase intentions path.

This study contributes to the literature on sustainability showing how producers and retailers may together influence consumers' pro-environmental purchase intentions. Findings extend the retail literature on the impact of producers and retailers' policies on consumers' sustainable purchases. Further, environmental concern is investigated in its moderating role on the impact of external factors on consumers' pro-environmental purchase intentions.
