The Influence of Social Environment and Green Marketing on Green Purchasing Behavior with Environmental Behavior as a Mediating Variable

Abstract

This research examines the relationship between social environment and green marketing on green purchasing behavior, with environmental behavior serving as a mediating variable. As environmental concerns escalate globally, understanding the factors that drive consumers toward sustainable purchasing decisions becomes paramount for businesses and policymakers. This study aims to provide insights into how social influences and marketing strategies affect consumers' environmental behaviors and subsequent purchasing decisions. The research employs a quantitative approach, surveying consumers across various demographic segments. The findings suggest that both social environment and green marketing significantly influence green purchasing behavior, with environmental behavior partially mediating these relationships. These results offer strategic implications for businesses seeking to develop more effective sustainability initiatives and marketing approaches.

Introduction

Environmental degradation and climate change have become pressing global concerns, prompting increased attention to sustainable consumption patterns. Consumer behavior theory traditionally focused on economic factors influencing purchase decisions, yet contemporary research emphasizes the growing importance of environmental considerations in consumer choice frameworks. The concept of "green purchasing behavior" consumers' preference for environmentally friendly products has emerged as a critical area of study in marketing and consumer research.

Two main external factors influencing green purchasing are social environment and green marketing. The social environment encompasses the cultural norms, peer influences, and societal pressures that shape individual attitudes and behaviors. Meanwhile, green marketing refers to the development and promotion of products based on their real or perceived environmental sustainability. Between these external factors and actual purchasing behavior lies environmental behavior the individual's attitude and actions toward environmental preservation, which may mediate the relationship between external stimuli and consumer actions.

This research aims to explore how social environment and green marketing collectively and independently influence consumers' environmental behavior and consequently their green purchasing decisions. Understanding these relationships is crucial for businesses developing sustainable marketing strategies and for policymakers designing interventions to promote environmentally friendly consumption patterns.

Research Framework

The conceptual framework of this research examines three key variables:

• Social Environment (Independent Variable) Includes peer influence, cultural norms, family values, and societal expectations regarding environmental responsibility.
• Green Marketing (Independent Variable) Encompasses corporate environmental claims, eco-labeling, green advertising, and sustainability-focused product positioning.
• Environmental Behavior (Mediating Variable) Refers to consumers' environmental attitudes, knowledge, and general pro-environmental actions.
• Green Purchasing Behavior (Dependent Variable) The actual tendency to select environmentally friendly products and services over conventional alternatives.

Based on this framework, the study tests four main hypotheses:

• H1: Social environment has a significant positive effect on green purchasing behavior.
• H2: Green marketing has a significant positive effect on green purchasing behavior.
• H3: Social environment has a significant positive effect on environmental behavior.
• H4: Environmental behavior mediates the relationship between social environment/green marketing and green purchasing behavior.

Literature Review

Social Environment and Green Purchasing Behavior

Research demonstrates that social environment significantly influences consumer behavior across domains (Feldman, 2020). In the environmental context, consumers are more likely to adopt sustainable practices when they observe similar behaviors among peers and family members. Social norms theory posits that individuals adjust their behaviors to match perceived social expectations (Cialdini et al., 2019). Studies have shown that social influence affects environmental attitudes and preferences for green products (Robinson et al., 2021).

Collective environmental consciousness within communities creates normative pressures that promote pro-environmental behavior. When environmental responsibility becomes a valued social norm, consumers experience both intrinsic and extrinsic motivation to align their purchasing decisions with social expectations (Kilbourne et al., 2018). This influence is particularly potent when consumers perceive that significant others value environmental sustainability.

Green Marketing and Green Purchasing Behavior

Green marketing strategies aim to influence consumer preferences by highlighting the environmental benefits of products and services. Effectiveness of green marketing depends on several factors including message credibility, perceived product quality, and relevance to consumer values (Chen, 2019). Research indicates that consumers respond positively to transparent, verifiable environmental claims but are skeptical of vague or exaggerated assertions (Polonsky et al., 2020).

The effectiveness of green marketing varies across consumer segments based on environmental concern, knowledge, and perceived consumer effectiveness (D'Souza et al., 2021). For highly environmentally conscious consumers, green marketing serves as a signal reinforcing existing preferences, whereas for less concerned consumers, effective messaging can stimulate environmental awareness and preferences for sustainable options.

Environmental Behavior as a Mediating Variable

Environmental behavior encompasses attitudes, knowledge, and habitual actions related to environmental protection. Theory of Planned Behavior suggests that individual attitudes significantly influence behavioral intentions, which then affect actual behavior (Ajzen, 2020). Environmental behavior may mediate the relationship between external influences and specific purchasing decisions by shaping underlying environmental consciousness.

When consumers develop strong environmental behaviors through social influences or green marketing exposure, they are more likely to translate these general pro-environmental tendencies into specific purchasing decisions (Bamberg & Mser, 2022). This mediation effect suggests that interventions focusing on shaping environmental attitudes may have cascading effects across various consumer behaviors.

Methodology

This research employs a quantitative cross-sectional design using survey methodology. The target population consists of adult consumers with purchasing decision authority in their households. A random sampling approach was used to select 500 respondents, representing various demographic segments including age, income level, and geographic location.

The measurement instrument includes validated scales adapted from previous research. Social environment was measured using items assessing peer influence, social norms, and community environmental consciousness. Green marketing was evaluated through perceived frequency and effectiveness of environmental marketing messages encountered. Environmental behavior was measured using items assessing environmental attitudes, knowledge, and general pro-environmental habits. Green purchasing behavior was assessed through self-reported frequency of selecting environmentally friendly alternatives across product categories.

Data analysis included descriptive statistics, reliability testing, confirmatory factor analysis, and structural equation modeling to examine relationships between variables and test the mediation hypothesis.

Results and Discussion

The analysis revealed significant relationships among the study variables. Both social environment (=0.38, p<0.001) and green marketing (=0.32, p<0.001) showed positive direct effects on green purchasing behavior, supporting hypotheses H1 and H2. Social environment demonstrated a stronger relationship with green purchasing behavior compared to green marketing, suggesting the critical importance of social influences in sustainable consumption decisions.

Regarding the mediation hypothesis, environmental behavior partially mediated both relationships. The indirect effects through environmental behavior were significant for both social environment (=0.14, p<0.01) and green marketing (=0.11, p<0.01). The direct effects remained significant when accounting for the mediation, indicating partial rather than full mediation. These findings support hypothesis H4 and highlight the role of environmental behavior as an important pathway between external influences and purchasing decisions.

The results align with theories suggesting that both external social influences and marketing efforts can shape consumer behavior through attitude formation. The stronger effect of social environment relative to green marketing emphasizes the power of normative influence in promoting sustainable consumption. However, the significant impact of green marketing suggests that strategic environmental messaging remains an effective tool for businesses seeking to influence purchasing behavior.

The partial mediation indicates that while environmental behavior represents an important mechanism, social environment and green marketing also directly influence purchasing decisions through alternative pathways. Consumers may occasionally purchase green products due to social pressure or effective marketing without necessarily having deeply internalized environmental values, suggesting multiple routes to influencing sustainable consumption.

Demographic analysis revealed interesting patterns, with younger, higher-educated, and urban consumers showing stronger relationships between environmental behavior and green purchasing behavior. Women demonstrated higher overall environmental behavior but similar responsiveness to social environment and green marketing compared to men.

Conclusion and Implications

This research demonstrates that social environment and green marketing significantly influence green purchasing behavior, with environmental behavior serving as an important mediating variable. The findings have several implications for theory, business practice, and public policy.

From a theoretical perspective, this study contributes to the growing body of research on sustainability behaviors by highlighting the interconnected roles of social influences, marketing strategies, and individual environmental consciousness. The partial mediation suggests that existing consumer behavior models should incorporate multiple pathways to explain green purchasing decisions.

For business practitioners, the findings suggest that effective sustainability strategies should address both the social and marketing dimensions of consumer behavior. Companies should consider developing community-based initiatives that leverage social norms around environmental responsibility while simultaneously ensuring their green marketing efforts are credible, verifiable, and aligned with consumer values. The stronger influence of social environment suggests that businesses might benefit from creating platforms for consumers to share and demonstrate their sustainable choices, thereby harnessing the power of social proof.

For policymakers, the results support interventions that foster environmentally positive social norms alongside traditional information campaigns. Policies that make sustainable behaviors visible and socially commendable may create multiplier effects beyond individual messaging efforts. Educational programs focusing on environmental behavior formation may yield broad impacts across various consumption domains.

Limitations of this study include its cross-sectional design, which limits causal inference, and its reliance on self-reported behavior, which may be subject to social desirability bias. Future research could employ experimental or longitudinal designs to better establish causality and examine the long-term evolution of environmental behavior and its impacts on consumption patterns.

In conclusion, as environmental challenges intensify, understanding and promoting green purchasing behavior becomes increasingly important. This research highlights that both social environment and green marketing play significant roles in driving sustainable consumption, with environmental behavior serving as a critical bridge between external influences and consumer actions. By addressing these multiple dimensions, businesses and policymakers can develop more comprehensive approaches to fostering environmentally responsible consumption.
