There is limited research examining the relationship between social media and green food purchasing behaviour. In the current study, we examine the factors that affect consumers’ green food purchasing behaviour in Türkiye.

Data collected from the participants by survey method were analysed using Smart PLS 4.0 with IBM SPSS 26 and PLS to run SEM.

Our findings have revealed that from all the structural elements in the theory of planned behaviour (TPB), only attitude and perceived behavioural control contribute to consumers’ green food purchasing behaviour, while subjective norms do not contribute to consumers’ green food purchasing behaviour. Additionally, it was found that social media usage (SMU) and digital marketing interactions (DMI) have a positive and significant effect on green food purchasing behaviour. More information, experiences, opinions and recommendations on green foods in social media channels can encourage consumers to buy more green food.

This study first evaluates the applicability of the TPB model in explaining green food purchasing behaviour. This study is extended with two new factors included in the original framework of the TPB model, namely, SMU and DMI.

The purpose of this paper is to examine the purchase behavior of consumers towards green products by adapting and extending the theory of planned behavior with the inclusion of three pertinent environmental factors posited to reflect environmental consciousness in the form of environmental concern, environmental knowledge and environmental values.

The data was collected from 410 consumers at shopping malls with retail stores selling green and non-green products in a developing country using cluster sampling and analyzed using covariance-based structural equation modeling.

The findings of this study indicate that environmental factors reflecting environmental consciousness positively influence consumers’ attitude towards purchasing green products, wherein consumers’ environmental values have a stronger influence than their environmental concern and environmental knowledge. The findings also reveal that subjective norm, attitude and perceived behavioral control toward purchasing green products positively shape green purchase intention. The same positive effect is also witnessed between green purchase intention and behavior. However, perceived behavioral control towards purchasing green products had no significant influence on green purchase behavior.

This study suggests that green marketers should promote environmental consciousness among consumers to influence and shape their planned behavior towards green purchases. This could be done by prioritizing efforts and investments in inculcating environmental values, followed by enhancing environmental knowledge and finally inducing environmental concern among consumers. Green marketers can also leverage subjective norm and perceptions of behavioral control toward purchasing green products to reinforce green purchase intention, which, in turn, strengthens green purchase behavior. This green marketing strategy should also be useful to address the intention–behavior gap as seen through the null effect of perceived behavioral control on purchase behavior toward green products when this strategy is present.

This study contributes to theoretical generalizability by reaffirming the continued relevance of the theory of planned behavior in settings concerning the environment (e.g. green purchases), and theoretical extension by augmenting environmental concern, environmental knowledge and environmental values with the theory of planned behavior, resulting in an environmentally conscious theory of planned behavior. The latter is significant and noteworthy, as this study broadens the conceptualization and operationalization of environmental consciousness from a unidimensional to a multidimensional construct.

This research study uses the theory of planned behavior to investigate the factors such as environmental concern, perceived control behavior and subjective norms that foster green purchasing intention in the developing market, with the moderating influence of environmental knowledge.

Convenience and purposive sampling were used to obtain data from 418 respondents, which were analyzed using structural equation modeling.

The findings revealed that environmental concern had a significant impact on the subjective norms, green attitude and perceived behavioral control; subjective norms had a positive impact on the green attitude, did not on perceived behavioral control and green purchase intention directly; perceived behavioral control had a significant impact on green attitude directly but did not green purchase intention; green attitude had a significantly impacted the green purchase intention. Environmental knowledge had a strong moderation association between green attitude and green purchase intention.

The study explores the complex relationships between various factors, including environmental concern, subjective norms, perceived behavioral control, green attitude and environmental knowledge, and their impact on green purchase intention which can provide a more nuanced understanding of the drivers for sustainable consumption. Additionally, the study's finding on the moderating effect of environmental knowledge on the relationship between green attitude and green purchase intention may be a novel contribution to the existing literature.

This study examines the relationship between green psychological benefits and green apparel purchase behavior using stimulus–organism–response (S-O-R) theory and a serial multiple mediation model.

Data were collected from 250 Lithuanians using a standardized questionnaire. Convergent and discriminant validity analyses were performed to ensure validity and reliability, and variable relationships were assessed using structural equation modeling.

The findings revealed utilitarian environmental benefits and warm glow benefits positively impacted Generation Z's (Gen Z's) attitudes toward green apparel. In contrast, the self-expressive benefits had no effect. In addition, attitude and purchase intention significantly predict green apparel purchase behavior. Attitudes and purchase intentions are crucial as serial mediators between green psychological benefits and green apparel purchase behavior.

These findings provide valuable insights for policymakers in Lithuania and highlight the importance of emphasizing the psychological benefits to encourage the purchase of green apparel. Moreover, policymakers and marketers should design apparel products that appeal to Gen Z, promoting green apparel adoption. By leveraging the stimulus–organism–response (S-O-R) theory, this research contributes to understanding pro-environmental behavior. It bridges the gap between attitudes, intentions and actual behavior in sustainable fashion research.

This study aims to examine the direct and indirect influence of electronic word of mouth (eWOM) on green cosmetics purchase intention of young Vietnamese female consumers through health concern, environmental concern and the theory of planned behavior (TPB) factors.

Data were collected from a survey of Vietnamese young female consumers that were analyzed using a partial least squares structural equation modeling.

The results reveal that eWOM has a direct effect on consumers’ purchase intention of green cosmetics. Among TPB factors, attitude was a greater influential predictor of purchase intention than subjective norms. However, the influence of perceived behavioral control on purchase intention was not supported. There were significant indirect effects of eWOM on purchase intention through the mediation of health concern, environmental concern and attitude.

Therefore, the findings of this study are relevant for marketers and managers as they provide valuable insights into understanding the motivational factors of consumers’ green cosmetics purchase intention. The results highlighted that eWOM could increase young female consumers’ environmental concern and health concern, which, in turn, influence a positive attitude toward green cosmetics. Hence, eWOM is a powerful vehicle for environmental and health messages; also, it can be an important channel of sensitization toward environmental and health issues and motivation of proenvironmental behavior and healthy lifestyle.

The study contributed to the literature by confirming the utility of the TPB model in predicting young women’s green cosmetics purchases in the context of Vietnam, an emerging market, which has largely been overlooked in the literature. The findings show that eWOM has a direct influence on green cosmetics purchase intentions of young Vietnamese female consumers and indirectly eWOM through health concern, environmental concern and two TPB factors (attitude and subjective norms).

This study aims to examine the factors that influence the increase in purchase intention toward green batik products with religiosity as an intervening variable.

The study used a survey method that involved a sample size of 185 participants selected through purposive and accidental sampling techniques. The analysis was conducted by using IBM SPSS AMOS 21 software. The collected data were subjected to path analysis using multiple linear regression models.

The result indicated that religiosity plays a mediating role in the association between factors and the intention to purchase green product (GPd) of the Indonesian natural dye batik product. This finding is in accordance with the construction of theory of planned behavior in understanding consumer purchase intentions. GPd, green brand and green price exhibited a positive correlation with green purchase intention (GPI). Interestingly, the price was found to no longer serve as the primary factor in GPI.

The analysis would have been more compelling if it had used a mixed-method approach by introducing the variables of customer satisfaction and promotion.

This research postulates that increased prices are no longer a deterrent to the purchase of GPd. Instead, consumer consciousness regarding GPd plays a pivotal role in driving GPI. GPd have revolutionized individuals’ consumption patterns to contribute to environmental preservation. The use of green batik products is seen as advantageous in helping mitigate environmental degradation.

The present research assesses the impact of religiosity, as an intervening variable, on the augmentation of GPI by gauging its significance in enhancing ecological consciousness and moral values.

This study aims to examine the gender differences in purchase intention towards green packaging product. The paper extended the theory of planned behaviour by unravelling the dynamics of quality, product attributes, and green packaging as part of strategic elements for the marketing mix.

A cross-sectional-survey-based questionnaire research design was used to collect data from a total of 212 adults from Malaysia. Partial least squares structural equation modelling was used to assess the measurement and the proposed research model.

The results showed that perceived quality and product attributes had a positive relationship with attitude towards green packing products without significant difference between female and male groups. Interestingly, this study found a significant difference between males and females in terms of the attitude and subjective norms towards intention to purchase green packaging product. Subjective norms had a positive relationship with attitude while perceived behavioural control had a positive relationship with purchase intention without significant gender differences.

The findings of this study contribute to the limited body of knowledge in the area of purchasing green packaging products and provide useful information to industry practitioners about gender differences in purchasing green packaging products. Also, the current study provided new insights to the academician by looking into the dimension of green marketing mix elements which influence consumer behaviour.

This research intends to investigate the determinants that affect consumers’ purchase intention of electric vehicles (EVs) in Malaysia using an extended theory of planned behaviour (TPB).

Survey data were collected with a sample size of 306. The research used SmartPLS 4.0 structural equation modelling tool to analyse the data. Reliability and validity tests (discriminant and convergent validity) were used and subsequently assessed the measurement and structural models. Mediation analysis was conducted to identify the role of the latent constructs.

The findings indicated that a green purchase attitude plays a complete mediation role in the effect of environmental knowledge on the purchase intention of EVs. In the same notion, the effect of price perception and availability of charging facilities on the purchase intention of EVs passes completely through perceived behavioural control. However, the subjective norm was an insignificant mediator of the impact between government support and EV purchase intention.

This paper helps to examine the latent constructs that impact purchase intention using environmental knowledge, government support, price perception and the availability of charging facilities. Successful green marketing and a sustainable consumerism framework are seen as a booster to promote the usage of EVs in Malaysia.

An extended TPB model has been employed in this research to study the effects of the above-mentioned constructs. The results show that most of the extended constructs are significant in explaining the purchase intention. The empirical results address the gap in the consumer green attitude and provide insight into this area of study.

This comparative research examines the factors influencing individuals' purchase intention toward green housing. By examining these factors, this study provides fruitful insights into the purchase intentions and behaviors for greenhouses among individuals of different age groups in India.

Data were gathered from Generation (Gen) X (313) and Generation (Gen) Y (297) using self-administered questionnaires. The “partial least squares structural equation modeling” was used to test the hypotheses.

The outcome shows that attitude and green trust substantially impact the green purchase intention of Gen X and Y. More specifically, environmental knowledge insignificantly influences the green purchase intention of Gen X while significantly influencing Gen Y. However, perceived risk insignificantly affects the purchase intention of both Gen X and Y. Consequently, green purchase intention substantially impacts the green purchase behavior in both studies.

This research focuses primarily on India; future research may be conducted in different geographical contexts. This study could also be extended to all age groups individuals.

The findings of this article facilitate policymakers, real estate developers and professional bodies in formulating strategies for sustainable nations in the future.

The current article is the initial empirical attempt to examine the home-buying decisions of individuals in India. Moreover, the role of Generation X and Generation Y in green housing purchase decisions will provide fruitful insights into how different age groups impact the decision-making process of green housing.

The purpose of this study is to use the theory of planned behavior and a moderated mediation model to bridge the gap between attitude, intention and behavior in the context of green consumption. The study will focus on how environmental corporate social responsibility initiatives play a positive moderating role in the mediation effect of green purchase intention on the relationship between attitude toward green products and environmentally friendly purchasing behavior.

A representative sample of 583 consumers was gathered from five major cities in Vietnam using a mall-intercept survey method. The moderated mediation model and the formulated hypotheses were tested using the PROCESS macro.

The results of our study reveal that green purchase intention is not only positively and directly associated with environmentally friendly purchase behavior but also significantly mediated the green purchase attitude–behavior link. Environmental corporate social responsibility initiatives were found to positively moderate the direct effect of attitude toward green products on green purchase intention. More importantly, our study also yielded that the mediation effect of green purchase intention on the relationship between attitude toward green products and environmentally friendly purchase behavior is positively moderated by environmental corporate social responsibility initiatives. As such, the indirect impact of environmentally friendly purchase attitude on green purchase behavior through green purchase intention was stronger when the level of environmental corporate social responsibility initiatives was higher.

The results of this study have practical implications and offer valuable recommendations for marketing practitioners, administrators and policymakers. These recommendations can help promote corporate social responsibility practices among firms, encourage environmentally friendly consumption among consumers and contribute to the overall sustainable development of the country.

This study has made significant contributions to the existing literature on pro-environmental behavior by addressing the gap between attitude, intention and behavior in sustainable consumption. Furthermore, to the best of the author’s knowledge, this is the first study to use a moderated mediation model to shed light on the moderating effect of environmental corporate social responsibility initiatives on the direct and mediated relationships among attitude, intention and behavior in the context of green consumption.
