The purpose of the current study is to help remove the obstacles to sustainable production and consumption by revealing the determinants of green consumption behaviour, which is one of the precursors of sustainable economic growth. This study aims to expand the theory of planned behaviour (TPB) model and contribute to the relevant literature by investigating the factors of social media usage, social media marketing and digital marketing interactions that have not been investigated before in relation to green product purchasing behaviour.

This study examines the effect of the extended TPB model on consumers’ intention to buy green products in Turkey, which has a Middle Eastern culture and is a developing economy. In the study, data collected from 409 participants with the questionnaire method were analysed using SmartPLS 4.0 and IBM SPSS 26 statistical programs.

The study findings revealed that all the structural elements of TPB (attitude, subjective norms, personal behaviour controls) and social media marketing and digital marketing interactions contribute to consumers’ green product purchasing behaviour. The study findings also demonstrated that the use of social media is not effective in the purchasing of green products.

Understanding consumers’ perspective on purchasing green products is crucial for policymakers, businesses and marketers, as it helps formulate appropriate strategies to support sustainable economic growth. In this respect, this study has important implications for sustainable consumption and production. In addition, to the best of the authors’ knowledge, the study is the first to examine consumers’ green product purchasing behaviour in the context of sustainable economy.

The theory of planned behavior (TPB) served as a framework for identifying major antecedents of everyday green purchasing behavior and for determining their relative importance.

The German market research institute GfK provided data (n = 12,113) from their 2012 household panel survey. A two-step structural equation modeling approach was applied to test both the measurement and the structural model.

Willingness to pay (WTP) was the strongest predictor of green purchasing behavior, followed by personal norms. The impact of attitude is insignificant. This implies an attitude – behavior gap.

Individuals overestimate their self-reported WTP and behavior, which suggests that the share of explained variance is in reality lower. It has to be doubted whether consumers are objectively able to judge products by their environmental impact. Even if consumers are willing to buy a “greener” product, their subjective evaluation might be incorrect. Further research should be based on actual purchasing data. In addition, the attitude – behavior gap should be scrutinized by further research to identify further barriers to green consumption.

Consumers need to be aware that their consumption behavior can make a difference. They have to value the benefits of green products and understand why these are priced higher. Firms can apply pricing and promotional strategies addressing personal norms and inducing a higher WTP to capitalize on the opportunities of the green market segment.

The study integrates WTP and personal norms as critical predictors into the TPB and furthermore expands the extant literature on green purchasing behavior to cover daily consumer goods extending beyond organic food. This enhances understanding of the structure of the constructs and determines their relative importance.

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.

This study investigates the influence of consumption values on green Fast-Moving Consumer Goods (FMCG) purchase behaviour in the context of green household cleaning products in the Western Province of Sri Lanka.

We used the survey strategy and 326 effective responses as the sample of this study.

Our findings reveal that specific consumption values, specifically functional, conditional and epistemic values, significantly impact green FMCG purchase behavior towards green household cleaning products. However, social and emotional values did not substantially influence this behavior.

The results of our study suggest practical implications for green FMCG marketers aiming to boost consumer adoption of green household cleaning products in Sri Lanka. To achieve this, marketers should focus on enhancing consumer value perceptions and strategically emphasize the consumption values consumers prioritize. Green FMCG marketers have a competitive advantage in the Sri Lankan market by doing so.

This research addresses a notable gap in the literature concerning green FMCG purchase behavior related to green household cleaning products within international and local contexts. Furthermore, this study distinguishes itself by adopting the Theory of Consumption Values as its foundational theory, offering fresh insights compared to previous research employing alternate theories, such as the Theory of Planned Behavior and the Theory of Reasoned Action, to examine similar phenomena.

This study aims to explore the determinants of the green purchase behaviour (GPB) of environment-friendly and energy-efficient electronic products market. It specifically examines the moderating effect of consumers’ moral identity on the relationships between the consumption values and GPB of environment-friendly and energy-efficient electronic products market. It also examines the direct relationship between consumption values and GPB.

In this study, the theory of consumption values is combined with the moral identity of consumers. A structured questionnaire mall-intercept survey was used to collect data from 396 respondents, which was subsequently processed using the smart PLS software for partial least square structural equation modelling analysis.

Findings reveal that functional value, social value, conditional value and epistemic value are the significant predictors of GPB of the environment-friendly and energy-efficient electronic products market. The moral identity of consumers also appears to positively moderate the relationships between functional, emotional and conditional values and the GPB.

The energy efficiency of electronic products is included in this study as an additional feature of functional value, while government support and business promotional initiatives are incorporated as the new elements of conditional value. Therefore, the inclusion and evaluation of the moral identity of consumers, alongside new elements of functional and conditional values in the theory of consumption values, could be considered a significant theoretical addition. The study uncovered certain customer insights that could help accelerate the adoption of green electronic products, which may result in better energy savings, reduced carbon emissions and environmental safety.

The purpose of this paper is to understand consumers’ purchase intention toward green apparel products using the theory of planned behavior (TPB). Specifically, this study aimed to compare US and Chinese consumers to understand how green apparel behaviors differ by a country’s green market status and cultural differences.

By employing two antecedents, man-nature orientation and environmental knowledge into the TPB framework, a theoretical model was proposed and tested to explain how and to what extent each variable affected the purchase intention of US and Chinese consumers. To compare the two countries consumers’ purchase intention, moderating effects were proposed. To test this model, a total of 437 valid data sets were collected at universities in the USA and China.

Findings indicated that the subjective norm was found to have the highest direct influence on purchase intention in both countries. Regarding internal perceived behavioral control (PBC) and external PBC, internal PBC was important for purchase intention in the US consumers while external PBC significantly influenced purchase intention among Chinese consumers. For the USA, two indirect antecedents to purchase intention (man-nature orientation and environmental knowledge) positively influenced variables in the TPB. In contrast, for China, the path between man-nature orientation and attitude toward green apparel products was not supported, but all other paths were supported. Only environmental knowledge (indirect antecedent) positively influenced internal PBC. Country moderating effects were not tested because of lack of supported evidence of invariance tests.

This study is an empirical research that focuses on purchase intention of green apparel products rather than on the production of green textiles, a topic that has received considerable attention in previous studies. This research is based on TPB with specified indirect antecedents to purchase intention. By testing the proposed model, the study explains the paths from two indirect antecedents (i.e. man-nature orientation and environmental knowledge) to the intent to purchase green apparel products. Therefore, academically, this study contributes to understanding the interrelationships among the factors that lead to purchase intention of green apparel products.

In this research, the effect of green logistics in e-commerce on consumer purchasing behaviour is examined. Companies that have adopted green logistics are thought to be effective on consumer’s product preferences. Businesses are sensitive to changing environmental conditions and changing consumer behaviour and that they adopt green logistics in line with their development goals is a factor that can affect the purchasing behaviour of consumers. Therefore, ‘adoption of the green principle’ becomes a social and global phenomenon.

When consumers evaluate a product or service, they look at not only product performance and quality, but also the environmental impact of the product. The fact that the enterprises realised this, their responsibilities in terms of environmental impact, their achieving competitive advantage, and their aim to strengthen their brand image in the market led them to adopt the green principle. In this respect, the importance of R&D studies has been understood and activities related to this subject have increased. These activities ultimately reduced both living conditions and lifecycle costs. Green brand awareness has increased in consumers. The use of technology in commerce has expanded e-commerce and has become a part of life. In this context, it should be investigated whether the development of environmental consciousness of the consumer in e-commerce has an effect on the product selection. According to the findings of the research about the effect of green logistics practices on the buying behaviour of firms, it is determined that the environmental awareness and demands of the consumers are highly effective in the adoption of green logistics and that the green logistics practices in e-commerce affect the purchasing behaviour of the consumers. At this point, a green approach in national or international commercial activities has been exhibited and also needs to be executed.

This research extends the theory of planned behaviour (TPB) and aims to study the underlying factors that influence Chinese consumers' purchase intentions towards green products. The conceptual model encompasses four elements (subjective norms, perceived behaviour control, moral norms and attitude) and one consumer response (purchase intention).

The current research employs a questionnaire survey and two experiments. In Study 1, the hypotheses were tested using structural equation modelling with 485 consumers in China. Study 2 employed a single-factor, two-condition (morally engaged vs control), between-subject design.

The findings reveal that the morally extended TPB framework is more applicable in predicting Chinese consumers' green purchase intentions than the original TPB model. Attitude plays the most significant role in predicting purchase intentions, and moral norms prove to be a mediator of the relationship between the original construct of subjective norms and purchase intentions. The findings further revealed that moral norms comprise the underlying mechanism of the relationship between subjective norms and attitude.

This study therefore expands the TPB theory by including moral norms. Moreover, it contributes to the literature by clarifying the direct, indirect and total effects of each TPB element on the purchase intentions towards green products. Finally, managerial implications are given.

The concept of green marketing has emerged as a panacea for reducing the negative impact of business activities on the environment. Many studies have investigated the impact of green marketing on green purchase behavior, sustainable competitive advantage, etc., without much being explored about how green marketing translates into firms' profitability, particularly among small and medium enterprises (SMEs) in emerging markets. This study, therefore, investigates the influence of green marketing on perceived SME profitability alongside the mediating effect of green purchase behaviour.

A quantitative research approach was adopted, where a cross-sectional survey design was employed to collect the data from 400 SME owners/managers in Ghana. Using Statistical Package for Social Science, the data were analysed through descriptive statistics, correlation and macro Process version 3.4.1.

The results reveal that the dimensions (environmental knowledge, environmental concern, green price, green advertising and green product) of green marketing distinctively have significant positive effect on perceived SME profitability as well as green purchase behaviour. Furthermore, green purchase behaviour significantly mediates the relationship between green marketing dimensions and perceived SME profitability such that the indirect effects are far greater than the direct effects.

SME managers should include the green marketing dimensions in their business plans and develop strategies to implement them in order to enhance green purchase behaviour of their products and services which will, in turn, lead to profitability.

In augmenting green marketing literature, this study provides an insight into how SMEs can leverage on the distinct dimensions of green marketing to influence green purchase behaviour and profitability in an emerging market context.

Green consumer behavior has recently attracted the attention of academic researchers. To address a lack of relevant research, the effects that consumer characteristics (i.e. external locus of control and collectivism) and social influence factors (i.e. environmental visibility and subjective norms) exert on green purchasing intentions are investigated in this study. The paper aims to discuss these issues.

Data were collected through a quantitative online survey of 1,866 participants in Taiwan, and structural equation modeling (SEM) was used to analyze the data.

The results show that although an external locus of control exerted a negative effect on consumers’ green consumption intentions, collectivism values exerted a positive influence. In addition, both environmental visibility and subjective norms exerted a significant effect on green purchasing intentions.

Consumer characteristics and social influence factors were integrated into green consumer research in this study. The findings can improve green market managers’ understanding of the role that consumer characteristics and social influence factors play in consumer decisions.
