The purpose of this paper is to provide the theoretical insights with regard to the green purchasing intention–behavior gap and the role played by social media influences in abating this gap. This paper takes into consideration a wider aspect with regard to the antecedents of behavioral intention through personal and social identities in place of the antecedents presented in the theory of planned behavior and social-identity theory. Furthermore, as the theories lack an explanation of how to reduce the intention–behavior gap, this paper also argues the source credibility model (SCM) in explaining the impact that social media influences can have on the behavioral gap.

Hypothetical deductive method is proposed for this concept paper under the positivism research paradigm.

Not applicable as this is a concept paper. However, the paper discusses the theoretical and managerial implications.

This is a concept paper. Yes this paper discusses the theoretical, managerial, and social/ecological implications.

This paper highlights the relevance of consumers' personal and social identities when consumers make purchasing decisions regarding green products. How managers can make marketing strategies, based on credibility model, involving social media influences as product endorsers and ambassadors, as well as the policy makers to design products, earmark consumer behavior and to conduct marketing campaigns in time to come.

As to how policies can be designed and adopted for bio-based economies where sustainability and circularity are given priority and to increase the attention of businesses moving toward sustainable practices.

Original thought developed based on research, theoretical and market gaps.

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 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 purpose of this study is to examine the contribution of environmental knowledge and environmental sensitivity on the green purchasing intention of Bangladeshi consumers by using an extended theory of planned behavior.

Quantitative research method was used to collect 369 data by using a convenient sampling method. Data was analyzed using partial least square while a structural equation model was applied to measure causal relations among the variables.

The findings of this study demonstrate that subjective norms, attitude toward green products and perceived behavioral control have a positive and significant relationship with green purchasing intention. Moreover, environmental knowledge has also a positive and significant relationship with environmental sensitivity. There is a positive and significant association between environmental sensitivity and attitude toward green products, while the relationship between environmental knowledge and attitude toward green products was found insignificant. Quality of green products does not moderate the relationship between attitude toward green products and green purchasing intention. The results further indicate that environmental sensitivity mediates the relationship between environmental knowledge and attitude toward green products. Attitude toward green products also mediates the relationship between environmental sensitivity and green purchasing intention. At the same time, environmental sensitivity and attitude toward green products jointly mediate the relationship between environmental knowledge and green purchasing intention. However, attitude toward green products does not mediate the relationship between environmental knowledge and green purchasing intention.

This study may be used to guide managers who are planning to launch green products in the Bangladeshi market for choosing their target markets and a great insight for the government to produce environmentally friendly consumption policy for citizens and environmental conservation.

This study aims to demonstrate how greenwashing perceptions shape the effect of environmental concern on post-millennials purchasing behavior.

Based on 174 responses gathered through a street survey method from 5 different universities in Turkey, data are analyzed using the statistical package for social sciences software (SPSS 16.0). Principal component analysis is performed to assess the differentiation in factors. Multiple regression analysis is used to examine the effects of the items on the post-millennials purchasing and recommendation behavior.

The main findings revealed that the environmental concern trait of post-millennials triggers their green purchasing behavior. When the concern on green products is high, the awareness of perceiving that “if the product is actually green or pretending to be green” is high. When the post-millennials take the greenwashing perception into account, their environmental concern has lower effects on their green behavior. The moderating role of greenwashing between environmental concern and green purchasing is apparent. Greenwashing perception decreases the effects of environmental concern on green behavior.

The research raises the concept of greenwashing perception that moderates the relationship between environmental concern and post-millennials purchasing behavior. This study also demonstrates that greenwashing awareness has a critical role in creating a purchasing behavior of post-millennials that have environmental concerns.

This paper aims to address the green purchasing gap by: exploring environmentally conscious consumers’ mental representation of the barriers responsible for the green purchasing gap; assessing which barriers are perceived as the most relevant in hampering the purchase of green products for environmentally conscious consumers; and investigating the relationships among these barriers. Although consumers are increasingly concerned about environmental deterioration, the current market share of green products remains fairly low.

An introspective qualitative study is conducted; 51 environmentally conscious consumers showing a green purchasing gap are interviewed, and the data are analysed with a cognitive mapping technique (Decision Explorer software) and Freeman’ structural indices (UCINET software).

Higher price and scarce availability of green products are the main barriers to green purchasing. However, consumers’ perceptions of price and availability may vary by changing other barriers (e.g. green products displacement inside the store and in-store communication).

This work reconstructs the decisional premises of environmentally conscious consumers’ choices to not purchase green products, identifies the most relevant barriers to green purchasing behaviour and the relationships between these barriers. With this knowledge, marketers of green products can focus on the most important barriers so that interventions in these barriers may change environmentally conscious consumers’ perceptions of other related barriers.

The purpose of this study is to measure the gaps between the engagements of shippers (i.e. logistics buyers) and logistics service providers (LSPs) in different green logistics practices (GLPs) throughout the key phases of the logistics purchasing process: request for proposal, negotiations, contracting and execution.

A large-scale survey of shippers and LSPs in Sweden was conducted. Respondents were 331 firms (169 shippers, 162 LSPs). Mean values of the actors' perceptions were analysed using independent- and paired sample t-tests.

While this study supports previous research indicating that LSPs engage more extensively in selling GLPs than shippers do in buying them, it shows that this conclusion does not uniformly apply to all GLPs nor all purchasing phases. Three patterns emerged for the gaps between the actors' buying-selling engagements throughout the purchasing process: (1) steady and wide gaps, (2) steady and narrow gaps and (3) emergent gaps. Distinct GLPs were associated with each pattern. It is also shown that the prioritisation of GLPs is fairly aligned between shippers and LSPs.

This study contributes to the green logistics purchasing literature by systematically and simultaneously creating three types of distinction, between (1) shippers and LSPs, (2) different GLPs and (3) different logistics purchasing phases. Future studies could replicate the analysis in countries other than Sweden.

Managers of shipper/LSP firms learn tips to spot the GLPs that their partners prioritise, enabling them to modify their purchasing/marketing strategies accordingly.

The three types of distinction represent a novel approach in the green logistics purchasing literature.

This study aims to examine the impact of the supplier's coercive and cognitive pressures on a manufacturer's green purchasing decision-making process and the resultant implications in terms of operational and environmental performances.

Path analysis is performed to test the hypothesized linkages.

This study finds that the supplier's coercive pressure, environmental focus and socio-cultural responsibility will lead a firm to more successful implementations of green purchasing, which, in turn, results in improved operational and environmental performances. The study findings reveal that the commercial values of green purchasing in addition to social and political obligations will promote the adoption of green purchasing in supply chain management practice.

This study helps business managers understand the impacts of the supplier's coercive and cognitive pressures on green purchasing and the manufacturer's resultant performances. In particular, coercive pressure is operationalized by the supplier's coercive pressure and environmental regulatory pressure, while cognitive pressure is reflected in the supplier's environmental focus and socio-cultural responsibility. This study contributes to the extant theories and enriches the literature on green purchasing.

The purpose of this paper is to ascertain the green-purchasing capabilities required to ensure the successful implementation of green-purchasing practices under the forces of institutional pressure. Specifically, this paper explores the green-purchasing capabilities of buyer firms under the influence of institutional pressures in supplier selection, development, collaboration and evaluation in support of environmental purchasing.

Questionnaire survey method was used to gather data from 163 ISO 14001-certified manufacturing firms in Malaysia. Partial least squares was used for hypotheses testing.

Green-purchasing capabilities, such as manufacturing, financial, intraorganisational and integration capabilities, have a significant positive effects on green-purchasing practices. However, innovation capabilities have no significant effect on green-purchasing practices. Regulation, customer and competitor pressure positively moderate the relationships between green manufacturing capabilities and practices.

The paper highlights the importance of green-purchasing capabilities in enhancing the green-purchasing practices of firms. The findings that pertain to moderating effect could be used to assist policy makers, particularly in setting appropriate policies and strategies to improve green purchasing.

Although more studies on green purchasing have been conducted in recent years, issues, such as the effect of green-purchasing capabilities on green-purchasing practices, are still unspecified. Besides, this study considers institutional pressure as the moderator when a model is constructed to exemplify the relationship between green-purchasing capabilities and practices.

This study aims to identify the determinants of customers' green purchasing behaviors. First, the study examines the relationship between green self-identity (GSI) and green peer influence (GPI) on green purchase behavior (GPB). Second, it examines the relationships between both GSI and GPI, and purchasing behavior mediated by green consumption values (functional value (FV) and social value (SV)). Third, it investigates the moderating effect of customer disidentification (CDI) on the relationships between GSI and both green consumption values. Finally, it investigates the indirect relationships between GSI and purchasing behavior moderated by CDI.

A quantitative study is conducted using a survey of 204 Egyptian buyers of organic food products. AMOS and Hayes's PROCESS macro are used to test the hypotheses under investigation.

The customer's peer influence and GSI are found to have a positive impact on green purchasing behavior. Additionally, the mediating impact of values and the moderating impact of CDI are also confirmed.

This study helps organic food companies in identifying the determinants of customers' green purchasing behavior. The results of the study will guide the efforts of green marketing professionals in promoting green products in the Egyptian market.

Since the notion of green consumption is still in its infancy, there is a need for further exploration on the green consumption concept to better understand customers' predictors of that type of consumption; accordingly, the current research was conducted.
