Green advertising, which promotes products based on their environmental benefits, has emerged as a powerful tool in influencing consumer intentions and encouraging sustainable choices. Green advertising has transformative impacts on buying intention of consumers towards green products, and this leads to advancement of economic sustainability. This study explorese the impact of green advertising and environmental knowledge on consumers' intentions to purchase eco-friendly products, addressing a critical gap in understanding the psychological factors that drive sustainable consumer behavior. Additionally, the study discusses the role of eco-branding, eco-labelling, and consumer innovativeness as moderators of the intention of green product purchase. The data was collected from 512 Chinese individuals and employed structural equation model for empirical analysis. Our findings reveal that green advertising has a significant positive influence on consumers' intention to buy green products, with environmental knowledge amplifying this effect. Additionally, factors such as eco-branding, eco-labelling, and consumer innovativeness further enhance consumers' inclination towards sustainable purchases. These insights highlight the importance of integrating educational elements into green advertising strategies and suggest that companies should invest in eco-labelling and branding to reinforce consumer trust and engagement with sustainable products. The empirical findings carry implications for refining green advertising strategies, suggesting increased investments in both green production and advertising initiatives.

Greenwashed Cigarette Ad Text and Imagery Produce Inaccurate Harm, Addictiveness, and Nicotine Content Perceptions: Results From a Randomized Online Experiment

INTRODUCTION

The tobacco industry has a long history of circumventing regulations to present their products, inaccurately, as less harmful. Greenwashing (portraying a product as natural/eco-friendly) is increasingly used by tobacco companies and may mislead consumers to believe that certain cigarettes are less harmful than others. This study assesses the effect of some common greenwashing tactics on consumer product perceptions.

AIMS AND METHODS

We conducted an online experiment with 1504 participants ages 18-29, randomized to view a cigarette ad manipulated for presence-absence of a combination of four different greenwashing techniques: greenwashed ad text, greenwashed ad imagery, recycled paper ad background, and image of greenwashed cigarette pack. Participants rated perceived absolute harm, relative harm to other cigarettes, absolute addictiveness, relative addictiveness, and relative nicotine content.

RESULTS

Participants who viewed ads containing greenwashed text were more likely to have inaccurate perceptions about absolute harm (AOR = 1.72), relative harm (AOR = 3.92), relative addictiveness (AOR = 2.93), and nicotine content (AOR = 2.08). Participants who viewed ads containing greenwashed imagery were more likely to have inaccurate perceptions of relative harm (AOR = 1.55), absolute addictiveness (AOR = 1.72), relative addictiveness (AOR = 1.60), and nicotine content (AOR = 1.48). Forty-two percent of those who saw an ad with all greenwashed features believed the product was less harmful than other cigarettes versus 2% of those who saw an ad without greenwashed features.

CONCLUSIONS

We found that greenwashed text and imagery produced inaccurate risk perceptions. More active U.S. Food & Drug Administration (FDA) enforcement against such greenwashing and new FDA rulemaking to prohibit unnecessary imagery in tobacco advertising and establish plain packaging requirements would help protect consumers and public health.

IMPLICATIONS

These findings provide evidence that greenwashing tactics used by the tobacco industry increase inaccurate product risk perceptions. These tactics could be a way for the industry to make implicit modified risk claims, despite applicable U.S. Family Smoking Prevention and Tobacco Control Act prohibitions. Findings from this study support the need for prohibitions on these tactics, and the potential for such prohibitions to help protect public health.

The need for individualization: An open innovation perspective on the case for customized products

In modern marketing, the emergence of mass customization has reoriented the focus from traditional marketing practices toward a customer-centric approach. The individualization feel among consumers and the innovative approach taken by businesses are currently evident in the market but has yet been holistically analyzed. This study applied a modified Theory of Planned Behavior by incorporating the need for individualization, hedonic and utilitarian motivations, with a 4Ps marketing mix - with the main objective to identify factors contributing to the intention to make purchase of customized products. The survey involved 311 participants who completed an online questionnaire utilizing purposive sampling approach, focusing on those who had previously bought customized products. Structural Equation Modeling was employed as a statistical method to analyze the data with SPSS AMOS v25. Findings revealed that the need for individualization proved to have the highest effect on the intention to purchase customized products, explaining that consumers who are strongly inclined toward individualization not only perceive greater value in customized products but also express a higher intention to purchase them. This was followed by its direct significant effect on attitude, with an even higher effect on perceived behavioral control, along with the marketing mix latent variable and customer perceived value on purchasing intention. This study offers valuable insights for retail brand management and provides potential strategies for business improvement. Moreover, a valuable contribution to the limited literature on the promotion of customized product purchases was identified. Lastly, the developed framework and implications may be applied and extended by future research in the consumer behavior field.

Comparative analysis with animal-derived products reveals the high content of medium-chain triglycerides (MCTs), essential vitamins, and minerals in coconut, contrasted with its lower protein content. Researchers have underscored the environmental sustainability of coconut, advocating for its role in eco-friendly food production chains. We have also addressed challenges like potential allergies, nutritional balance, sensory attributes, and consumer motivations for coconut-based products, in terms of understanding the market dynamics. In conclusion, this review positions coconut as a promising candidate within sustainable diet frameworks, advocating for further research to augment its nutritional value, sensory characteristics, and product stability, thereby facilitating its integration into health-conscious and eco-centric dietary practices.

Green Consumer Profiling and Online Shopping of Imperfect Foods: Extending UTAUT with Web-Based Label Quality for Misshapen Organic Produce

Misshapen organic vegetables in the food supply chain can easily be discarded in the market if they do not meet aesthetic standards. E-commerce technology enables the distribution of imperfect organic produce from farmers to potential customers, mitigating agri-food waste issues. Green consumers are prospective customers of imperfect produce because their purchasing decisions are made based on sustainability and environmental considerations. However, each individual's degree of green consumption differs, impacting their preferences and behaviors toward green buying activity. Considering the gap between the varying levels of green consumers and their intention to purchase imperfect organic produce through e-commerce, this study aimed to profile three distinct green consumers and explore factors affecting their Online Green Purchase Intention (OGPI) for imperfect organic vegetables. The Unified Theory of Acceptance and Use of Technology (UTAUT) was applied in this study, and Web-Based Label Quality (WLQ) was introduced as an extended construct to describe green consumers' perceptions of the credibility and reliability of labels or product-related information displayed on e-commerce platforms. This study involved 668 internet users from environmental platforms and online communities of organic food enthusiasts. First, the consumers were classified into dark-green, semi/light green, and non-green using a cluster analysis approach. Then, Structural Equation Modeling (SEM) and Multi-Group Analysis (MGA) were employed to determine the factors affecting OGPI among green consumer groups. This research found that Performance Expectancy (PE), Social Influence (SI), and WLQ positively influenced dark-green consumers' online green purchase intention. Only Performance Expectancy (PE) positively affected semi/light-green consumers' OGPI. Meanwhile, the Facilitating Condition (FC) positively affected non-green consumers' online green purchase intentions. This research revealed dark-green consumers as the target segment, broadening customers' perspectives on accepting imperfect organic products, including e-commerce technology. Moreover, the research results can be utilized for marketing and business purposes and contribute to food policy.

Is there any way to increase consumers' purchase intention regarding surplus food blind-boxes? An exploratory study

As an emerging business model, merchants are selling surplus food in blind boxes, which provides new opportunities for reducing waste and promoting sustainable development. Surplus food blind boxes, however, have not been extensively researched in terms of design and marketing strategies. Therefore, we are examining how to increase consumers' purchase intention regarding surplus food blind boxes as well as the relationship between purchase intention, continuous intention, and recommendation intention. In this paper, two studies are conducted. As part of study 1, We used factor analysis to explore the reasons that influence consumers to purchase. In study 2, we utilized structural equation modeling to examine the impact of purchase intention on continuous intention and recommendation intention. Results indicate that food quality, perceived sustainability, and conspicuous consumption are the most important positive factors. The most important negative factors are perceived food risk, resistance to sales techniques, taste anxiety, and inadequate marketing strategies. Based on our findings, we constructed a path relationship between purchase intention, continuous intention, and recommendation intention. The purchase intention of the surplus food blind box users directly influences the recommendation intention and the continuous intention, while the recommendation intention indirectly influences the continuous intention. This study did not demonstrate that gender had a moderating effect. Meanwhile, it provides a reference for the actual marketing management of surplus food blind box merchants.

Trust and website conversion in consumer responses to green product purchasing: A new perspective through the lens of innovative website Design's technology integration

This study aims to investigate the role of trust and website conversion in consumer responses to green product purchasing, with a new perspective through the lens of innovative website design's technology integration. To achieve this objective, an online survey was conducted with a sample of 384 consumers in Thailand. The results reveal that user trust in innovative website design are significant predictor website conversion in consumer responses to green product purchasing. Innovative website design's technology integration positively influences anticipated website usability and anticipated website quality requirements, which, in turn, enhances trust and leads to increased consumer conversion to green product purchasing. Moreover, anticipated website quality requirement acts as a partial mediator in the relationship between technology integration of innovative website design and user trust in innovative website design. The relationship between user trust in innovative website design and conversion of consumer response to green product purchase is notably strong (β = 0.203, p-value = 0.014), with user trust accounting for roughly 57.1 % of the variability in consumer conversion (R 2 = 0.571 ). This substantial link suggests that in the broader context, enhancing elements that build trust within a website's design is crucial as it influences over half of the consumer's decision-making process related to green product purchases. Essentially, for industries and markets centered around eco-friendly products, investing in strategies to bolster user trust in their digital platforms could significantly drive consumer response and engagement. These findings have important implications for marketers and website designers seeking to enhance their green product sales by developing innovative website designs that incorporate technological integration and build trust with consumers. Both markers and website designers can use these insights to optimize their website design strategies, leading to increased conversion rates.

Impact of green factors on undergraduate students' green behavioral intentions: A hybrid two-stage modeling approach

Consumers' unsustainable behavior contributes to environmental degradation and impedes sustainability. Using green products is one way to reduce this effect and promote environmental growth. Therefore, this study aims to investigate the green factors that impact young customers' behavioral intentions regarding green products. For this purpose, the researcher designed a research model based on the expanded theory of planned behavior (TPB). The study adopted a two-stage, hybrid model using partial least square-structural equation modeling (PLS-SEM) and necessary condition analysis (NCA) to evaluate and validate the results. A sample of 382 undergraduate students was gathered using a convenience sampling approach. The results reveal that green TPB perception (GTP), green price sensitivity (GPS), green product trust (GPT), and green product value (GPV) are significantly and positively correlated with green behavioral intention (GBI). This study's main contribution is adding a brand-new higher-order construct, GTP, in the environmental and marketing literature and validating its effect on GBI. Again, environmental awareness moderates the association between GPS and GBI. Furthermore, the NCA's findings indicated that these variables are necessary to various degrees for students' GBI. Decision-makers may use the study's insights to create successful regulations to better understand young customers and develop appropriate green initiatives for sustainable development.

Environmentally Responsible Purchase Intention in Pacific Alliance Countries: Geographic and Gender Evidence in the Context of the COVID-19 Pandemic

The objectives of this research were: (1) to examine the influence of environmental awareness (EA), sustainable consumption (SC) and social responsibility (SR) on the environmentally responsible purchase intention (ERPI) of consumers in the member countries of the Pacific Alliance, namely, Chile, Colombia, Mexico and Peru; and (2) to analyze whether there is a moderating effect related to the country of residence and gender of the consumer. The study was conducted under a quantitative and cross-sectional approach. The sample consisted of 1646 consumers: 24.4% from Peru (n = 402), 25.4% from Mexico (n = 418), 26.1% from Colombia (n = 401) and 24.1% from Chile (n = 397). Data analysis and hypothesis testing were performed using a multigroup Structural Equation Model (SEM). The results show a positive influence among environmental awareness (EA), sustainable consumption (SC) and social responsibility (SR) on environmentally responsible purchase intention (ERPI). Gender and country of residence were also shown to be moderating variables in these relationships. In conclusion, it can be affirmed that the participants of this study recognize the importance of acquiring environmentally friendly products. Among them, the female population is more aware of this issue. It is recommended new business models be created to provide products and services oriented to this market according to consumers’ tastes, desires and purchasing preferences; the proposals they have should be friendly to the environment and to society.

Understanding the Green Procurement Behavior of Household Appliance Manufacturing Industry: An Empirical Study of the Enablers

Green procurement, as a crucial green supply chain practice, contributes to sustainability achievement and reduces carbon emissions by selecting sustainable suppliers or outsourcing partners. The green procurement of household appliance manufacturing can reduce carbon emissions from the source and increase the competitiveness of products. To help better understand the driving powers and influential mechanism of green purchasing behavior for household appliance manufacturers, the green procurement mechanism is investigated by presenting an empirical study considering both endogenous and exogenous factors. A survey-based questionnaire is designed, and a semistructured interview is conducted for data collection. Besides, the structural equation model (SEM) approach is employed to test the supposed hypotheses and proposed assumptions based on the collected 529 questionnaire responses. The empirical results show that exogenous driving powers are more inclined to encourage household appliance manufacturers to perform green procurement strategy compared with endogenous factors. Additionally, the business strategy, governmental regulations, and customer awareness show greater influence on green purchasing behavior, while the corporate culture, production system, and suppliers have little impact. Taxation policies, environmental awareness, and green strategies are the three main driving factors for promoting green procurement from the governmental, individual, and organizational dimensions. This empirical study assists to investigate potential factors affecting green purchasing behavior and helps to disclose the influential mechanisms from a systematic viewpoint. Results derived from the empirical analysis could assist to achieve sustainability by better understanding green purchasing behavior and better promoting green procurement strategies.

Green Trust as a Mediator in the Relationship between Green Advertising Skepticism, Environmental Knowledge, and Intention to Buy Green Food

Changing individual habits towards greener choices is an essential ingredient in tackling the environmental crisis. Engaging in green behavior may improve psychological wellbeing. Although the intention to buy green products is widespread, the eco-friendly market is struggling to leave the ground. Greenwashing can increase skepticism towards green advertising, which in turn can hinder the intention to buy green products. Conversely, a better knowledge of environmental issues can promote a positive attitude towards environment and thus the intention to purchase green products. This study aimed to investigate if trust in green claims can mediate the relationships of green advertising skepticism and environmental knowledge with the intention to buy green food. An online survey was administered to 410 Italian consumers (63% female; 18-78 years). Our mediation model explained 23% of the variability in intention. Trust fully mediated the relationship between green advertising skepticism and intention to buy green food, while it partially mediated the relationship between perceived environmental knowledge and intention. Specifically, GAS was associated with lower INT through lower TR, whereas PEK was linked to higher INT though higher TR. The findings of this study can provide green market operators and policy makers with valuable information to encourage green food purchases.

A Thematic Review on Using Food Delivery Services during the Pandemic: Insights for the Post-COVID-19 Era

The food delivery service is the most typical and visible example of online-to-offline (O2O) commerce. More consumers are using food delivery services for various reasons during the COVID-19 pandemic, making this business model viral worldwide. In the post-pandemic era, offering food delivery services will become the new normal for restaurants. Although a growing number of publications have focused on consumer behavior in this issue, no review paper has addressed current research and industry trends. Thus, this paper aims to review the literature published from 2020 to the present (October 2022) on consumers' use of food delivery services during the pandemic. A thematic review was conducted, with 40 articles searched from Scopus and Web of Science being included. Quantitative findings showed current research trends, and thematic analyses formed eight themes of factors influencing consumer behavior: (1) technical and utilitarian factors, (2) system-related attributes, (3) emotional and hedonic factors, (4) individual characteristics, (5) service quality, (6) risk-related factors, (7) social factors, and (8) food-related attributes. The paper also emphasizes COVID-19-related influences and suggests promising future research directions. The results offer insights into industry practices and starting points for future research.

Analysing the Influence of Companies’ Green Communication in College Students’ Green Purchase Behaviour: An Application of the Extended Theory of Planned Behaviour Model

In recent years, there has been a growing concern about the environmental impacts of consumers’ behaviour. As this environmental awareness increases, consumers tend to focus more on green products and how purchasing these products represents an effective way to protect the environment. Through the application of the theory of planned behaviour (TPB), in this research, we studied the influence of some key variables on college students’ green purchasing behaviour, namely perceived behavioural control, subjective norms, green attitudes, and green purchase intentions. The TPB model was extended to the analysis of the influence of the companies’ green communication on students’ green purchase behaviour. To achieve the proposed goal, from March to April of 2021, a survey was conducted among the students of a higher education institution (HEI) in Portugal, allowing us to gather 432 valid responses. The findings suggested that all the variables, except the subjective norms, had a positive influence on the students’ green purchase intentions. Moreover, it was observed that students’ intentions had a positive influence on their green purchase behaviour. This research provides important results not only for policymakers to promote more sustainable behaviours among consumers but also for companies to be more aware of the importance of green communication.

Consumer Behavior in Online-to-Offline (O2O) Commerce: A Thematic Review

Online-to-offline (O2O) commerce is a popular business model which links offline business activities with online channels. Consumer behavior in O2O commerce is more complex than in other traditional business models as both online and offline channels are involved. Despite the growing number of publications focused on this issue, no review paper has discussed the current research trends and factors influencing consumer behavior in O2O commerce. Therefore, this review aimed to synthesize literature on O2O commerce from 2015 to April 2022, focusing on consumer behavior. A set of inclusion and exclusion criteria was developed for searching and screening articles from two dominant databases (i.e., WOS and Scopus), and 53 eligible articles were included in this review. A thematic review approach using ATLAS.ti 9 software was conducted. Quantitative results presented the research trends of O2O commerce. Qualitative analyses generated eight main clusters of factors which influence consumers’ O2O behavior: (1) service and product quality, (2) technical and utilitarian factors, (3) emotional and hedonic factors, (4) trust and risk, (5) price and cost (6), social factors, (7) online content, and (8) habit. This paper also highlighted promising future research directions. The findings are expected to benefit the sustainable management and the future research of O2O commerce.

Pull the Emotional Trigger or the Rational String? A Multi-Group Analysis of Organic Food Consumption

The organic food industry in China has been developing fast with the increasing consumer demand for healthier, safer, and more nutritious foods since the epidemic outbreak. It is of great significance to understand the psychological preference of consumers for organic food and adjust the marketing strategy accordingly. In this study, we adopted the multi-group structural equation model (SEM) to analyze 571 questionnaire data and explored the effects of consumers’ perception on the sensory appeal of organic food, perception on promotional stimulation, positive emotion, and perceived social value on the purchase intention of organic food. Based on the Stimulus–Organism–Response (S-O-R) model, this study divides the route affecting organic consumption behavior into the rational route and emotional route. It was proved that the emotional route (positive emotion) has a greater impact on the purchase intention of organic food than the rational route (perceived social value). In addition, there are different purchase intentions among different product types. Specifically, compared with organic tea, positive emotion has a greater effect on the purchase intention for organic rice. This study provides an important reference for the organic food-marketing strategy of enterprises.

Factors Influencing the Purchase Intention for Recycled Products: Integrating Perceived Risk into Value-Belief-Norm Theory

Recycling used materials is one way to deal with the depletion of natural resources available on earth. Companies increasingly integrate recycled materials into their production processes and transition towards circular business models. However, although the attitude towards sustainable products is positive, consumers still prefer to buy products made from new instead of recycled materials. Empirical research on factors influencing the purchase intention of recycled products is still limited. This study aims to examine consumers’ individual factors that are important in the decision process to buy recycled products. The Value-Belief-Norm (VBN) theory is explored in the context of recycled product purchase intention. Perceived risk is added to the research model as a moderator that hinders purchase intention. The different influences are analyzed using partial least squares structural equation modelling with a sample of 177 respondents from Germany. Results indicate that the causal chain of relationships between values, beliefs, and personal norm has a positive influence on recycled product purchase intention. Perceived risk, on the other hand, has a significant negative direct effect on purchase intention but strengthens the relationship between personal norms and purchase intention. Theoretical and managerial implications as well as avenues for further research are discussed.

Fostering a Clean and Sustainable Environment through Green Product Purchasing Behavior: Insights from Malaysian Consumers’ Perspective

Rapid economic developments have led to the excessive consumption of environmental resources. Consumption patterns play a crucial role in deteriorating environmental conditions and influencing consumers to seek sustainability features while purchasing different products. The purpose of this paper was to analyze the sustainability factors that have prompted consumers in Malaysia to buy green products. The primary elements of this research focused on environmental concern, green product awareness, government support, perceived ecological value, community green practice, purchase intention, and green product purchase behavior. Additionally, to explain the relationship between the independent and dependent variables, this research employed the theory of planned behavior as a theoretical framework. A total of 300 questionnaires were collected and examined using smart PLS-SEM. The findings of the research suggest that all factors, including environmental concern, green product awareness, government support, perceived ecological value, community green practice, and purchase intention, influence consumers in Malaysia to purchase green products. Finally, this research discusses the contribution, limitations, and suggestions for future studies related to purchasing behavior towards green products.

Influence of Publicity and Education and Environmental Values on the Green Consumption Behavior of Urban Residents in Tibet

Faced with ecological environmental issues and a surge in the consumption of products in the Qinghai-Tibetan Plateau, it is necessary to explore the effective driving mechanism of green consumption behavior. This study investigated the impact of publicity and education on green consumption behavior and explored the mediating effects of environmental values and the moderating effects of price sensitivity. A cross-sectional survey was conducted with a sample of 500 questionnaires, which were randomly distributed by stratified random sampling to municipal government departments, public institutions, communities, streets, shops, and supermarket entrances in Lhasa, Shan Nan, and Xigaze in Tibet. Further, structural equation modeling was applied to derive data for statistical analyses. Publicity, education, and environmental values had a significant influence on green consumption behavior. Environmental values play a mediating role in the influence of publicity and education on green consumption behavior. Price sensitivity negatively moderates the relationship between publicity and education and environmental values; when considering the price of green consumption, the positive impact on environmental values is weakened by publicity and education. Furthermore, it moderates the mediating effect of environmental values. Publicity and education remain the primary intervention for promoting green consumption. Especially in areas with ethnic minorities, publicity and education in combination with the characteristics of ethnic areas should be used to promote the traditional Tibetan culture of respect for all life and to live in harmony with nature. Moreover, policies, regulations, and tax subsidies related to green consumption should be improved while reducing the negative impact of prices and other economic factors on the propensity to consume. These findings provide empirical evidence for the complex relationship between government intervention measures and urban residents' green consumption behavior.

An Exploratory Study of Consumers’ Knowledge and Attitudes about Lignin-Based Sunscreens and Bio-Based Skincare Products

Daily consumption of synthetic sunscreens is harmful to the environment and consumers’ health, so greener alternatives need to be produced. Lignin is a multifunctional and widely available biopolymer that can replace several ingredients, but its dark color and low sun protection limit its perceived usefulness. With a survey made for this study, we explored the knowledge and attitudes of 230 consumers towards lignin-based sunscreen, their motives and barriers to purchase it, and how it relates to their environmental and health consciousness. Participants were also asked about their sunscreen habits, their familiarity with the environmental and health impacts of skincare, their perceptions of bio-based ingredients in general, and their skincare product purchasing decisions. Those who are more familiar with environmental issues have a positive attitude towards bio-based ingredients, are accustomed to purchasing more environmentally friendly skincare, and are likelier to be interested in a lignin product. Consumers are welcoming towards a natural, healthy, and environmentally friendly sunscreen alternative but are worried about the lower SPF. Because organic is perceived as luxurious, they are concerned about its price, and some are apprehensive about its pigmentation. While a lignin-based sunscreen at this stage of development is unlikely to take on the role of primary sunscreen on warm, sunny days, it may be more useful as a general-purpose, everyday product that can offer some protection, moisture, and coverage.
