Environmental Consciousness in the Digital Era of Online Shopping: A Systematic and Bibliometric Review

ABSTRACT


INTRODUCTION
Environmental consciousness in business encapsulates the critical awareness of the environmental impact arising from business activities and the commitment to adopting sustainable practices to mitigate these effects [1].This holistic approach involves a careful consideration of the environmental ramifications of business decisions, encompassing the utilization of renewable resources, reduction of energy consumption, active participation in green programs, promotion of recycling efforts, and the integration of eco-friendly production processes.
Central to this consciousness is environmental awareness, a state where individuals grasp the imperatives for the wellbeing of the environment [2].This awareness correlates positively with pro-environmental behavior, forming a crucial link between understanding and sustainable actions.However, despite positive consumer attitudes towards eco-friendly products and services, a notable reluctance to pay for them persists, presenting a paradox for companies promoting sustainability [3].Bridging this gap requires strategic insights from behavioral science, suggesting approaches such as leveraging social influence, cultivating good habits, and deciding whether to appeal to the heart or the brain [4].
Issues of environmental concern have gained significant traction in both business and academic spheres, reflecting a growing apprehension within the industry, among retailers, and within the consumer base regarding the impacts of modern consumerism on the environment [5].Motivators such as values, beliefs, and personal ethics play pivotal roles in influencing individuals' actions in response to environmental concerns.
The surge in online shopping, a prominent feature of the modern consumer landscape, has intensified scrutiny on its environmental impact.Studies addressing this concern reveal that while online shopping generally exhibits a lower carbon footprint compared to traditional shopping, the actual environmental impact remains contingent on multiple variables [6].Environmental consciousness, shaped by factors such as knowledge, cognitive elements, attitudes, beliefs, social psychology, education, and technological awareness, significantly influences the environmental impact of online shopping [6].
To contribute to sustainability, companies can adopt various measures, including reducing energy waste, incorporating sustainable products, minimizing packaging waste, supporting environmental initiatives, and consciously managing deliveries and returns [7].Despite a growing consumer interest in sustainability, there exists a reluctance to pay a premium for eco-friendly products.Insights from behavioral science [8] continue to provide valuable guidance, emphasizing the importance of social influence, habit formation, and the choice between appealing to emotions or rationality.
The overarching goal of this article is to unravel the intricate interplay between environmental consciousness and online shopping.This exploration extends to an analysis of the field's representation, considering factors such as journal, publication year, country, and methodological contexts.Moreover, the research seeks to examine the progression of current literature concerning environmental awareness and online shopping, identifying researched topics and highlighting potential directions for future investigation.
The study endeavors to address key research questions, exploring trends in publication over the last thirteen years, identifying influential authors, assessing current publishing tendencies, highlighting crucial journals, determining significant contributing countries and institutions, evaluating the interconnection between environmental consciousness and online shopping, mapping the development of this relationship over time, and unraveling the network of bibliometric coupling of sources, documents, and countries.The study also aims to elucidate the predominant keywords used by authors, employing bibliometric keyword co-occurrence analysis in this field.
This study investigates the environmental consciousness in online shopping research, aiming to uncover trends, key contributors, institutional affiliations, geographical distributions, document types, journal publications, citation patterns, keyword usage, and bibliographic coupling networks through a systematic and bibliometric analysis of existing literature.Hence it addresses the following research questions: RQ1 investigates the trends in this research area based on the year of publication, while RQ2 examines which authors contribute the highest number of articles.RQ3 focuses on identifying the top publications by institutions, and RQ4 explores the distribution of articles by countries.RQ5 delves into the document types across subject areas of research.RQ6 aims to identify the top journal publications and the number of articles they have published.RQ7 investigates the authors of the most cited articles and summarizes their research contributions.RQ8 analyzes the most frequently used keywords in previous articles.Finally, RQ9, RQ10, and RQ11 explore bibliographic coupling networks by authors, sources, and countries, respectively, providing insights into the interconnectedness and collaboration within this research domain.
This paper follows a logical organization.Section 1 initiates with a comprehensive exploration of environmental consciousness in online shopping.Section 2 delves into a detailed review of relevant literature.Section 3 expounds upon the research methodology applied for the metadata analysis.Section 4 synthesizes the results and engages in a nuanced discussion of metadata analysis and bibliometric insights.Finally, Section 5 concludes the paper, offering insights into future research directions and acknowledging the study's limitations.

Environmental consciousness and online shopping
Environmental concern, defined as "an affective attribute that can present a person's worries, compassion, likes, and dislikes about the environment" [9], plays a pivotal role in consumer decision-making processes.This sentiment is particularly evident in the realm of organic food purchases, where, Grunert [10] identified environmental concern as a key determinant.Moreover, Bang et al. [11] established a positive association between consumers' emotional involvement with environmental issues and their willingness to pay for renewable energy.Lee [12] reinforced this perspective, highlighting environmental concern as a robust determinant of environmentally responsible behavior.
The concept of environmental concern extends beyond a mere affective evaluation, encompassing a consumer's emotional stance on environmental issues [12].Frequently conceptualized as a precursor to environmental purchase intentions, researchers have explored the relationship between environmental concern and consumers' preparedness to support environmentally friendly firms [13].However, the magnitude of this relationship remains inconsistent, giving rise to questions about the equivocal role of environmental concern in environmental purchasing decisions [14][15][16].
In light of these inconsistencies, an emerging issue in the literature is the exploration of whether environmental consciousness plays a significant role in online product purchases or purchase intentions for consumers.This inquiry seeks to unravel the dynamics of environmental concern in the context of the evolving landscape of online shopping.
Online shopping, a broad term encompassing the promotion and purchase of products/services through the internet and digital technology, diverges from traditional marketing approaches [17].It is characterized by elements of enjoyment, playfulness, and minimal effort, offering competitive prices, time efficiency, and the convenience of browsing a diverse array of products [18].The utilitarian value of online shopping lies in its facilitation of easy, transparent, and efficient transactions, saving consumers time and effort [19].
Despite these advantages, environmental considerations come into play, especially as online shopping has been found to have a lower carbon footprint than traditional shopping.Research from MIT [20] indicates that traditional shopping incurs a carbon footprint twice as large as that of online shopping.However, the environmental impact of online shopping is contingent on various factors, including consumer behavior, transportation, and packaging.Factors such as the customer's location and choice of transportation significantly influence the carbon footprint of traditional shopping [21].Moreover, issues like increased returns and additional packaging contribute to the negative environmental impact of e-commerce.While online shopping can be more environmentally friendly than traditional retail, it is crucial to consider the entire buying process and make sustainable choices to minimize its environmental impact [22].
The environmental impact of online shopping has been explored from various perspectives, revealing both advantages and challenges.Traditional shopping has a carbon footprint twice that of online shopping, indicating a potential environmental benefit of the latter [23].Rai [7] supported this by estimating and comparing the carbon footprints across different consumer behaviors and supply chain configurations, finding that online shopping is often the most environmentally friendly option.However, Argyridou [23] presented a more nuanced view, noting that online shopping results in five times more product returns and significantly higher emissions from packaging compared to brick-and-mortar stores.These returns, as examined by Tian and Sarkis [24], can contribute to over 30% of carbon emissions in online shopping, complicating the overall environmental assessment.For a further analyze shopping behaviors across demographics, affirming that while online shopping generally has a lower carbon footprint, its environmental impact remains substantial [8].Lastly, Zafar et al. [25] investigated the role of social media in promoting environmentally conscious consumption, finding that trust in social media and perceived environmental effectiveness significantly influence sustainable purchasing attitudes.
Together, these studies provide a comprehensive view of the environmental implications of online shopping, highlighting both its potential benefits and areas needing improvement.

METHODOLOGY
In this study, the selected dataset undergoes analysis using a science mapping method, a technique employed for scrutinizing existing literature that involves the examination of bibliographic data from a designated field of study [25].Bibliometric analysis is instrumental in mapping extensive scientific literature [26], and it adheres to a systematic approach akin to systematic literature reviews, employing rigorous techniques to ensure the quality of information and output results [27].VOSviewer version 1.6.20 software is employed by the author to construct and visualize linkages of bibliometric sources, identifying top authors, affiliations, and sources from the Scopus databases to extract refined information.
A second analysis is conducted using a Systematic Literature Review (SLR), which provides an objective, replicable, scientific, comprehensive, and transparent method for empirical research through a search of existing literature on key issues [28].The study adopts the Preferred Reporting Items for Systematic Review (PRISMA) standard.According to Kitchenham and Charters's study [29], three primary aspects of systematic reviews-planning, conducting, and reporting-are followed in this study, encompassing the identification of resources, study selection, data extraction, data synthesis, and report writing, as recommended by Kitchenham and Charters [29] and Kitchenham [30].
Additionally, through an SLR, researchers and practitioners in the management field can gain further information and knowledge on specific subjects that align with their cognitive, social, and political demands [31].With these considerations in mind, this research employs a systematic approach to collect data and categorize literary articles based on content analysis and potential research areas.In summary, the Prisma technique is employed in this study (Figure 1), involving the location of data, review of foundational data, addressing eligibility issues, and ultimately incorporating the data.
The search database or data, sourced from the Scopus database for meta-data evaluation, are considered reliable by many researchers [32].The purpose of gathering this data is to provide unique knowledge and research ideas for upcoming studies.
