Management of Green Competitive Advantage: A Systematic Literature Review and Research Agenda

: The success or failure of a company is acquired from a competition, which requires a speciﬁc strategy to achieve competitive goals and beneﬁts. One of these strategies is green competitive advantage (GCA) management, initially introduced in 2011, which is highly considered and identiﬁed as a management concept. Therefore, this study aims to evaluate a systematic review of GCA management. It emphasizes the analysis of trending literature, geography, and other factors inﬂuencing GCA. It also prioritizes the impact obtained when adopting GCA as a framework to support organizational sustainability. This study is the ﬁrst literature review that presents GCA management. The results show that the application of green innovation and high environmental awareness led to the development of improved performance, a better competitive advantage


Introduction
The emergence of various environmental governing regulations causes the lack of identification of several problematic conditions, especially for organizations having the potential to threaten ecological sustainability (Astuti and Datrini 2021).Using many natural resources, rapid worldwide industrial development causes serious environmental damage, leading to a decrease and increase in ecological quality and global warming, respectively.In this context, the impact of worldwide environmental conventions also changes the perspective of global industrial competition.These conventions include the following: (1) The Montreal Convention, (2) The Kyoto Protocol, (3) specific hazardous material restrictions, and (4) consumer environmentalism elevation (Chen 2011).However, many companies stated that organizational environmental management was an unimportant ineffective investment due to the inadequate understanding of the process as an essential development mechanism.According to some environmental reports, the occurrence of pollution emphasizes inefficient use of resources.In this case, companies seeking the adoption of environmental management (green innovation) have a significant advantage, indicating the enjoyment of more benefits toward the enhancement and development of green image and new markets (Chen 2008;Porter and Van der Linde 1995).Based on these results, environmental management was observed as one of the essential areas for corporate administration in the 21st Century (Chen and Chang 2013).This emphasizes a company's willingness to futuristically possess a green competitive advantage and sustainable business.
Based on sustainable development, corporate responsibility prioritizes the single bottom line (SBL), namely, the company's value only reflected in economic conditions.This responsibility also focuses more on triple bottom lines (TBL), indicating that the values are reflected in economic, social, and environmental conditions.This prioritization is only due to the financial condition's inadequacy to ensure the sustainable development of the company's value.The TBL concept was also established by John Elkington in his book, "Cannibals with Forks: the Triple Bottom Line of 21st Century Business", where three important components of sustainable development were observed, namely (1) economic growth, (2) environmental protection, and (3) social equity.During subsequent development, this concept was reduced to the 3Ps, namely profit, planet, and people.In the financial sector, the actualization of the TBL, especially for the environment, only occurred when all market actors (stakeholders) played appropriate and consistent roles in achieving sustainable development (Nugroho et al. 2017).To obtain a green competitive advantage (GCA), the maintenance of environmental management is then observed as an effort toward business sustainability (Chen 2008).Some environmental factors have also been observed to develop competitive advantages, such as product innovation and a green reputation.These are subsequently used to meet stakeholder expectations regarding environmental issues (Benevene et al. 2021).
Green competitive advantage (GCA) was first introduced by Chen (2011) by exploring competitive advantage with green innovation or environmental management.Based on Chen (2011), the definition of GCA is a condition where a company occupies several positions regarding environmental management or green innovation.In this context, the organization's competitors are often unable to imitate the adopted environmental strategy, which leads to the achievement of sustainable goals and benefits.From this definition, it is clear that GCA is an essential thing that a company must achieve through various resources owned to improve performance better than competitors.Research conducted by Chen (2011), with the experimental object being Taiwanese SME manufacturing companies, showed that environmental, organizational culture and leadership, as well as green organizational identity, increased GCA.Other research explores the relationship between green intellectual capital and green competitive advantage by focusing on the construct of green innovation and environmental protection.Based on the results, green human, structure, and relational capital had valuable relationships with GCA (Nivlouei and Khass 2014).Furthermore, there are differences in research results that explore the relationship between green human capital, eco-innovation, and GCA.These results indicate that green human capital and eco-innovation increased GCA (Astuti and Datrini 2021;Nivlouei and Khass 2014;Widiyati and Murwaningsari 2021), although they did not have positive and significant effects, respectively (Kuo et al. 2021;Lastanti and Augustine 2022).These differences are futuristically interesting for subsequent analysis to provide literacy and additional confirmation for the improvement of the GCA concept.
Although interest in GCA has been a significant uprising trend in recent years, there has not been a literature review focusing on green competitive advantage.Hence, it is the objective of the present study to fill in this research gap and provide a comprehensive discussion of green competitive advantage using a systematic literature review (SLR).SLR is a strategy used to evaluate the important parts of the literature for a specific field.SLR may assist the study's aims by pointing out the studies of interest with similar scopes, appraising them fundamentally in their techniques and putting them together in a measurable format when it can make a contribution.A total of 25 relevant articles published from 2011 to 2022 were located for the systematic literature review in order to compile the most recent research on green competitive advantage.Therefore, this study aims to propose GCA as a framework for evaluating and promoting organizational sustainability using a systematic literature review process.In this context, a systematic literature review (SLR) is specifically conducted to answer the following research questions: RQ1: What are the increasing trends and geographic analysis on GCA? RQ2: What factors are able to increase GCA? RQ3: What are the results for the organization when GCA is adopted?
The results show that the application of green innovation and high environmental awareness lead to the development of improved performance, a better competitive advantage, and sustainable business.This study highlights significant theoretical and practical contributions.From a theoretical perspective, it allows one to synthesize GCA outcomes to better describe how they affect organizations and the environment.From a practical perspective, it provides concrete implications for policymakers in defining the best mechanism for developing green innovation to achieve competitive advantage and business sustainability.Meanwhile, the actual outputs of this process are emphasized for practitioners, which subsequently enable easier access and increased GCA literacy for practitioners and stakeholders to encourage the selection of organizational GCs (green changes), especially concerning the role of GCA as a promotional and sustainable business framework.
This paper is structured as follows: Section 2 describes the literature review.Section 3 describes the research methodology, while Section 4 highlights the findings and discussions.Section 5 presents the study's conclusions and contributions.Finally, in the last section, we set out the limitations and future research agenda.

Resource-Based View (RBV) Theory
A resource-based view (RBV) is a managerial framework for determining organizational strategic resources to achieve a sustainable competitive advantage (Barney 1991;Ghozali 2020).This advantage highlights the merits of knowledge or an economy reliant on organizational assets, such as strategic resources.RBV was also initially pioneered by Penrose in 1959, where company resources were heterogeneous, with the available productive services originating from unique organizational assets (Kor and Mahoney 2004).This theory emphasizes internal organizational resources to identify the company assets, capabilities, and competencies with competitive advantage potential (Barney 1991).
A company is likely to have a competitive advantage regarding different strategy performances and possession of superior competitive resources.These resources need to be used as a source of sustainable advantage due to being valuable, rare, irreplaceable, and competitively inimitable (Barney 1991).They are also divided into three categories, namely tangible and intangible resources and human resource capabilities (Fahy and Smithee 1999).In this context, the capabilities emphasize the performance options of a company, using available organizational resources.In addition, the RBV approach states that the company achieves sustainable competitive advantage and obtains superior profits by controlling strategic tangible and intangible assets (Fahy and Smithee 1999).

Green Competitive Advantage (GCA)
The success or failure of a company is acquired from competition (Porter 1985), which requires a specific strategy to achieve competitive goals and benefits.This strategy prioritizes the achievement of success over the business competition with various competitors.Furthermore, a competitive advantage emphasizes the condition where a company's competitors are unable to imitate the ambitious strategy utilized for the achievement of goals and benefits (Barney 1991;Coyne 1986).This advantage is the primary source of a company's capabilities (Barney 1991), with environmental and social responsibility being a significant capability providing adequate organizational sustainability (Hart 1995).Therefore, environmental management is an essential element of corporate strategy, which should be considered a speciality regarding the RBV perspective (Hart 1995).
Based on Chen (2011), competitive advantage was explored with green innovation or environmental management, namely GCA (green competitive advantage) (Hart 1995;Husted and De Jesus Salazar 2006).This led to the definition of GCA as a condition where a company occupies several positions regarding environmental management or green innovation.In this context, the organization's competitors are often unable to imitate the adopted environmental strategy, which leads to the achievement of sustainable goals and benefits (Chen 2011).The GCA measurement also uses eight items, namely (1) the company has a low-cost competitive advantage regarding environmental management or green innovation, compared to its main competitors, (2) the quality of the environmentally friendly products or services provided is better than those of its counterparts, (3) the company has better abilities to carry out R&D environment and green innovation than its main competitors, (4) the company has adequate abilities to manage the environment compared to its counterparts, (5) the company's profitability is better regarding the environmentally friendly products or services, (6) the company's development exceeds that of its competitors based on the environmentally friendly products or services, (7) the main competitors are unable to easily imitate eco-friendly products or services, and (8) the competitors are unable to easily replace their distinctive position on environmental stewardship or green innovation (Barney 1991;Husted and De Jesus Salazar 2006;Porter and Van der Linde 1995).
According to Chen and Chang (2013), a new construct was proposed to measure GCA using 8 to 11 items.The proposition of these three items is as follows: (1) the company is the initiator and occupant in several essential areas regarding green products or services, (2) the company's environmental image is better than that of its main competitors, and (3) the competitors are unable to easily imitate the ideas of the company environmental ideas.Based on this theory, several previous reports were used as references for this present literature review.This is due to the belief that GCA is capable of achieving sustainable business processes for various organizations.The results obtained are expected to ensure the development of improved organizational performance, a better competitive advantage, and a sustainable business.

Methodology
In this systematic literature review, a method emphasizing the four stages of determination was used, namely journal selection, time horizon, article selection, and analysis (Halim 2010).

Journal Selection
This was carried out through the following primary sources, SCOPUS, Web of Science, and Google Scholar.In this context, the main reason SCOPUS and Web of Science were selected as the document search bases was that they have the largest peer-reviewed literature database in the world.These websites have the advantage of easy document search compared to other document indexing sites (Burnham 2006).The second reason is that they have article collections with high-quality standards, which means they are effective at finding the most relevant results.In addition, Google Scholar was used to determine other GCA-related articles not indexed by SCOPUS and Web of Science.

Time Horizon
The utilized time horizon included all publications indexed from the beginning of green competitive advantage publication (Chen 2011), from 2011 to April 2022.This period was chosen because GCA was introduced and published for the first time by Chen in 2011.
To learn more about trends and geographic analysis on GCA, the period up to 2022 was chosen in this study.

Article Selection
Based on the PRISMA workflow (Figure 1), the data collection process contained four steps.

Article Selection
Based on the PRISMA workflow (Figure 1), the data collection process contained four steps.Step 1 emphasizes identification, which is the use of a paper search in the SCOPUS, Web of Science, and Google Scholar databases, where the maintenance of various document sources is observed.In this process, the selection of keywords needs to be conducted to obtain relevant documents.This should be accompanied by filtering, which is often carried out through the observation of documents with specific criteria.These criteria commonly include document, author, and affiliation categories, with multiple varied and combined options used to easily search for specific alternatives.Regarding this analysis, the search process was performed by inputting the desired general keywords to determine the data emphasizing green competitive advantage.The keywords used were obtained from the title, and the keywords fields are {Green Competitive} AND {Competitive Advantage}.Papers written in the English language were also selected for use according to the search criteria.The inclusion and exclusion criteria set limited the type of journal articles to obtain documents that have been through a strict peer-review process compared to other document types (Table 1).We chose to derive data from the SCOPUS and Web of Science databases, which are known for their comprehensive coverage and the quality of the selected articles.Meanwhile, Google Scholar was used to determine other GCA-related articles not indexed by SCOPUS and Web of Science.When the Step 1 emphasizes identification, which is the use of a paper search in the SCOPUS, Web of Science, and Google Scholar databases, where the maintenance of various document sources is observed.In this process, the selection of keywords needs to be conducted to obtain relevant documents.This should be accompanied by filtering, which is often carried out through the observation of documents with specific criteria.These criteria commonly include document, author, and affiliation categories, with multiple varied and combined options used to easily search for specific alternatives.Regarding this analysis, the search process was performed by inputting the desired general keywords to determine the data emphasizing green competitive advantage.The keywords used were obtained from the title, and the keywords fields are {Green Competitive} AND {Competitive Advantage}.Papers written in the English language were also selected for use according to the search criteria.The inclusion and exclusion criteria set limited the type of journal articles to obtain documents that have been through a strict peer-review process compared to other document types (Table 1).We chose to derive data from the SCOPUS and Web of Science databases, which are known for their comprehensive coverage and the quality of the selected articles.Meanwhile, Google Scholar was used to determine other GCA-related articles not indexed by SCOPUS and Web of Science.When the eligibility criteria were met, the abstracts were then assessed for potential inclusion in the systematic review.

Inclusion Criteria Exclusion Criteria
Article discussing GCA Article not discussing GCA Documents type: peer-reviewed journal articles Conference proceedings, book chapters, etc. Type of study: empirical Review, conceptual paper, theoretical paper Language: English Non-English language Step 2 prioritizes screening, which is the independent collection and review of all the selected documental references, with the duplicate papers subsequently removed.This was accompanied by Step 3, which focuses on eligibility, where the final list of eligible papers was identified.Since the selected database enabled the pre-selection of full-text availability, year, and publication language, this manual procedure mainly considered keywords and paper content.This indicated that the papers with non-empirical and unrelated contents were omitted.Meanwhile, Step 4 emphasizes inclusion, where the selection process enables the identification of papers in the review.Twenty documents were excluded for not matching and not being relevant to the investigated topic (Appendix A Table A1).Based on these descriptions, a total of 25, 9, 11, and 5 papers were obtained according to the research topic, SCOPUS, Web of Science, and Google Scholar, respectively.

Analysis
Recapitulation was carried out on several selected literature reviews to determine the scientific trends of GCA.These reviews were sourced from the publications indexed by SCOPUS, Web of Science, and Google Scholar.The selected publications were then carefully read and categorized according to topic relevance.Data analysis also contained the following four steps: (1) describing the chronological distribution of the publications, (2) analyzing the characteristics of the involved participants and organizations, and (3) evaluating the content of the publications according to the study question.In this process, the first two steps did not directly address the study question, although they provided the necessary context to interpret and identify GCA results and gaps.Based on Steps 1 and 2, data analysis utilized a descriptive evaluation between countries, as well as the participant and organizational characteristics, respectively.Meanwhile, the analysis prioritized an in-depth review of GCA in Step 3. Table 2 shows the study characteristics, participants, and GCA constructs for each selected publication.

Discussion and Results
Based on the analytical steps, the results are presented below and divided according to the three features utilized in this report, namely the year, characteristics, and an in-depth review, specifically those emphasizing GCA and its outputs.

Chronological Distribution of the Papers
In the chronological distribution of publications, an increasing trend was observed from 2011 to April 2022 (Figure 2).

Discussion and Results
Based on the analytical steps, the results are presented below and divided according to the three features utilized in this report, namely the year, characteristics, and an indepth review, specifically those emphasizing GCA and its outputs.

Chronological Distribution of the Papers
In the chronological distribution of publications, an increasing trend was observed from 2011 to April 2022 (Figure 2).Since Chen (2011), only a few years have been observed for several scholars to become acquainted with this new concept.This showed an increasing trend of GCA analysis in 2011, 2012, 2013, 2017, and 2018, with one publication each.Moreover, two, three, seven, and eight publications were observed in 2014, 2020, 2021, and 2022, respectively.In this case, the analytical data for 2022 were only obtained until the first quarter of the year, with the most significant number of reports subsequently compared to previous years.This confirmed that more scholars were continuously interested in evaluating GCA as a framework for promoting organizational sustainability.

Studies Characteristics
In this report, three characteristics were analyzed, namely (1) the country responsible for data collection, (2) the organizational field used in the study, and (3) the type of employees involved in each organization.Based on the country of data collection (Figure 3a), the highest order was occupied by China (eight papers), accompanied by Taiwan, Since Chen (2011), only a few years have been observed for several scholars to become acquainted with this new concept.This showed an increasing trend of GCA analysis in 2011, 2012, 2013, 2017, and 2018, with one publication each.Moreover, two, three, seven, and eight publications were observed in 2014, 2020, 2021, and 2022, respectively.In this case, the analytical data for 2022 were only obtained until the first quarter of the year, with the most significant number of reports subsequently compared to previous years.This confirmed that more scholars were continuously interested in evaluating GCA as a framework for promoting organizational sustainability.

In-Depth Review
An in-depth review was conducted to obtain an understanding of GCA to answer the research questions.This review included five sections, namely (1) green innovation and GCA, (2) green intellectual capital and GCA, (3) GCA and sustainability, (4) GCA construct, and (5) further research opportunities.

Green Innovation and GCA
GCA is the exploration of competitive advantage through the implementation of green innovation or environmental management.According to the resource-based view (RBV), environmental and social responsibility is a resource or capability leading to a sustainable competitive advantage (Hart 1995).This indicates that environmental orientation substantially affects corporate green practice behavior as a strategic capability.In this process, the necessary resources and capabilities were promoted for the adoption of green practices.These results caused sustainable economic and environmental performance, ultimately leading to a feasible competitive advantage (Zameer et al. 2022).
Many companies often misunderstand and consider corporate environmental management an unnecessary and ineffective investment, which is quite harmful to organizational development (Chen 2011).However, some studies state that pollution only occurred due to the inefficient use of resources.In this case, the companies seeking to carry out environmental management had significant advantages, which led to higher benefits from green products.They also enhanced green images and developed new markets to obtain a competitive advantage (Chen 2008;Porter and Van der Linde 1995).
Based on this present review, extreme attention was devoted to the manufacturing industry due to several reasons.Firstly, the industrial sector is considered one of the main actors responsible for the environmental issues impacting sustainability.Secondly, the pressure exerted by consumers, stakeholders, and various regulations has forced the manufacturing industry to punctually switch to a green approach over other business sectors.Regarding the results, the orientation of the company described its business responsibility to the environment.This emphasized the importance of recognizing and minimizing the effects of companies on the environment.Subsequently, the application of green innovation or environmental management in different organizations ultimately and critically caused a sustainable competitive advantage.This proved that GCA is a win-win solution for the conflicts originating between environmental management and organizational and economic sustainability.

Green Intellectual Capital (GIC) and GCA
Intellectual capital contributes to value development through competitive advantage due to being an organizational intangible asset (Astuti and Datrini 2021).It is also an exploration of intellectual capital or intangible assets through the implementation of innovation or environmental management.GIC was initially introduced by Chen ( 2008) and classified into GHC (green human capital), GSC (green structural capital), and GRC (green relational capital).In this context, the organization's high-performing environmental and intangible asset activities were able to achieve a green competitive advantage.This was because of their commitment to environmental issues and investment in GIC (Chen and Chang 2013).
Based on the results, the interaction between the organization and the environment needs to be addressed to achieve a competitive advantage.In the environmental era, companies should also have good environmental knowledge to adopt environmental strategies.This indicates that the competitive advantage of an organization is obtained from environmentally friendly human resources.Moreover, the environmental knowledge inherent in individuals often plays an essential role for companies, specifically in developing green innovation and management.This proves that the business strategy and competitive ad-vantage of a company depends on its ability to facilitate environmentally-friendly economic activities.In this process, the strategic focus of an organization should be consistent with environmental standards, subsequently transforming potential threats into competitive advantages (Chen 2022).GIC is also a valuable asset for business organizations, which is used as a resource to obtain a competitive advantage.This intangible asset is divided into three essential classifications, namely GHC, GSC, and GRC.GHC emphasizes the knowledge, ability, and employee commitment to environmental protection.GSC also prioritizes commitment, capability, culture, image, organizational management system, and other factors related to organizational green innovation.However, GRC is an interactive relationship between the organization and external parties, including the customers, suppliers, and partners of organizational environmental management.Using GIC, the companies considering environmental issues achieved green competitive advantage, subsequently causing the development of organization sustainability.This was in line with the basic assumption of RBV theory, where many companies had different tangible and intangible resources capable of being converted into unique capabilities, such as competitive advantage.

GCA and Sustainability
Sustainability is often achieved when a business meets needs and wants without harming the environment (Duffett et al. 2018).Based on sustainable development, corporate responsibility prioritizes the single bottom line (SBL), which shows that the value of the company is only reflected in economic conditions.Subsequently, this responsibility highly emphasizes the triple bottom line (TBL), indicating that the values are reflected in economic, social, and environmental conditions.This prioritization only focuses on the inadequacy of the financial condition to ensure the sustainable development of the company's value.The TBL concept was also established by John Elkington in the book, "Cannibals with Forks: the Triple Bottom Line of 21st Century Business".In this publication, three important components of sustainable development were observed, namely (1) economic growth, (2) environmental protection, and (3) social equity.During subsequent development, this concept was reduced to the 3Ps, namely profit, planet, and people.In the financial sector, the actualization of TBL only occurs when all market actors (stakeholders) play appropriate and consistent roles in achieving sustainable development (Nugroho et al. 2017).To obtain GCA, the maintenance of environmental management is observed as an effort toward business sustainability (Chen 2008).Some factors are also observed to develop GCA, such as product innovation and green reputation, which are subsequently used to meet stakeholder expectations of environmental issues (Benevene et al. 2021).
Based on these results, a positive relationship was observed between GCA and sustainability.This proved that the companies implementing green innovation and environmental concern caused an improvement in performance and better competitive advantage, as well as developed a sustainable business.Since a sustainable company emphasizes the reduction of adverse ecological and social impacts, future generations need to have sufficient resources to meet their desires and succeed in the long term (Widiyati and Murwaningsari 2021).The results also showed that the manufacturing industry was the primary sector responsible for the environmental issues influencing sustainability.To carry out production activities toward the achievement of sustainability, the commitment of the manufacturing industry to environmental management is required using the TBL concept, namely profit, planet, and people.

GCA Construct
According to the analytical results, a total of 25 papers used 52 variables (Table 3).These were deliberately presented as references for the provision of insights to related scholars and practitioners.Further analysis was also carried out to analyze research clusters using Vosviewer 1.6.18(Figure 4).These clusters reflect the lines or strands of research pursued by the papers analyzed.
In the network visualization, items (keywords in our case) are represented by their label and, by default, a circle.The size of the label and the circle of an item is determined by the weight of the item.The higher the weight of an item, the larger the label and the circle of the keyword.The color of an item is determined by the cluster to which the item belongs.
In the network visualization, items (keywords in our case) are represented by their label and, by default, a circle.The size of the label and the circle of an item is determined by the weight of the item.The higher the weight of an item, the larger the label and the circle of the keyword.The color of an item is determined by the cluster to which the item belongs.Based on the definition of GCA, the most influential factors prioritized green innovation.These factors were subsequently categorized into two groups, namely (1) green innovation or environmental management variables and (2) variables emphasizing green innovation on intangible assets.There are 47 variables as the GCA construct for the green innovation or environmental management variables.Meanwhile, five variables emphasizing green innovation on intangible assets included (1) green intangible assets, (2) green human capital, (3) green structure capital, (4) green relational capital, and (5) green intellectual capital.This study initially introduced the definition and construction of GCA, with the experimental object being Taiwanese SME manufacturing companies.The results showed that environmental organizational culture and leadership, as well as GOI (green organizational identity), increased GCA (Chen 2011).

Environmental Manufacturer-Client Cooperation
This study analyzed the extent to which client involvement increased company performance in environmental issues.Environmental manufacturer-client cooperation also positively affected GCA, leading to the provision of opportunities for international market entries (Junquera et al. 2012).

Environmental Commitment and Green Intangible Assets
A new GCA construct was added and applied to the analysis of Taiwanese manufacturing companies.The results showed that environmental commitment and green intangible assets play major roles in business and GCA development (Chen and Chang 2013).Based on the definition of GCA, the most influential factors prioritized green innovation.These factors were subsequently categorized into two groups, namely (1) green innovation or environmental management variables and (2) variables emphasizing green innovation on intangible assets.There are 47 variables as the GCA construct for the green innovation or environmental management variables.Meanwhile, five variables emphasizing green innovation on intangible assets included (1) green intangible assets, (2) green human capital, (3) green structure capital, (4) green relational capital, and (5) green intellectual capital.This study initially introduced the definition and construction of GCA, with the experimental object being Taiwanese SME manufacturing companies.The results showed that environmental organizational culture and leadership, as well as GOI (green organizational identity), increased GCA (Chen 2011).

Environmental Manufacturer-Client Cooperation
This study analyzed the extent to which client involvement increased company performance in environmental issues.Environmental manufacturer-client cooperation also positively affected GCA, leading to the provision of opportunities for international market entries (Junquera et al. 2012).

Environmental Commitment and Green Intangible Assets
A new GCA construct was added and applied to the analysis of Taiwanese manufacturing companies.The results showed that environmental commitment and green intangible assets play major roles in business and GCA development (Chen and Chang 2013).This report had pragmatic implications due to using a practical method for measuring GCA in automotive companies, using four dimensions, namely environment, resource, capability, and knowledge.The results indicated that these dimensions increased the competitiveness of Chinese automotive companies (Li 2014).

5
Green Human Capital, Green Structure Capital, and Green Relational Capital This report explored the relationship between green intellectual capital and competitive advantage by focusing on the construct of green innovation and environmental protection.Based on the results, green human, structure, and relational capital had valuable relationships with GCA (Nivlouei and Khass 2014). 6 Green Knowledge Sharing, Green Service Innovation, and Green Dynamics Capabilities This study investigated the relationship between green knowledge sharing, service innovation, and dynamic capabilities with GCA.It also proved that these constructs had positive and increasing relationships with GCA (Lin and Chen 2017).

Green Marketing Tools
This report emphasized GCA from a multi-dimensional perspective and investigated the impact of green marketing tools on it within South African SMMEs.The results found that green marketing tools positively influenced increasing GCA (Duffett et al. 2018).

8
Green Market Orientation, Green Supply Chain Relationship Quality, and Green Absorptive Capacity This examines the effect of green market orientation (GMO), supply chain relationship quality (GRQ), and absorptive capacity (GAC) on GCA.Based on the results, GMOs did not directly affect GCA, although they had a significant influence due to the intervention of GRO and GAC.Meanwhile, GRQ and GAC positively and did not affect GCA, respectively (Lin et al. 2020).9 Green Creativity, Green Production, and Green Brand Image This study explored the factors strengthening GCA, namely green creativity, production, and brand image, in Chinese manufacturing companies.The results confirmed that all the factors directly and positively influenced GCA (Zameer et al. 2020).

Core Competence
The effect of core competence on GCA was analyzed in Indonesian chemical manufacturing companies.In this report, core competence positively affected GCA, leading to the development of organizational performance (Nuryanto et al. 2020).

11
Green Innovation, as well as Internal and External Environmental Orientations In the South African hotel industry, GCA was significantly influenced by green innovation, as well as internal and external environmental orientations.Several managerial implications were also observed, indicating that environmental orientation is the driving force for GCA, as hotel management needs to develop ecological strategies toward the achievement of sustainable goals (Fatoki 2021).
12 Green Process Innovation and Environmental Orientation Green process innovation and environmental orientation positively influenced GCA, leading to environmental performance improvement in Chinese manufacturing companies (Zameer et al. 2021).

E-Philanthropy, E-Community Involvement, E-Customer Wellbeing, and
Green Corporate Image This study determined the effect of green corporate image and the dimensions of ECSR (environmental corporate social responsibility) on GCA.These dimensions included e-philanthropy, e-community involvement, and e-customer wellbeing.The results showed that the green corporate image and ECSR dimensions directly and positively influenced GCA. Green corporate image also mediated the effects of the ECSR dimension on GCA (Alam and Islam 2021).
14 Green Human Capital, Green Structural Capital, and Green Relational Capital This study determined the relationship between environmental consciousness and green intellectual capital (GIC) with GCA.The utilized GIC components included green human, relational, and structural capital, which had significant positive relationships with GCA (Astuti and Datrini 2021).This examined the contribution of organizational green culture, business analytics, collaborative competence, and eco-innovation to GCA in Indonesian state-owned companies.Using 169 participants, organizational green culture and eco-innovation contributed positively to GCA.Meanwhile, collaborative competence and business analytics did not influence it (Widiyati and Murwaningsari 2021). 16 Green Human Resource Management (GHRM) This study used the ability motivation opportunity theory to determine the patterns by which green human resource management (GHRM) encouraged GCA improvement.The results confirmed that various companies leveraged GHRM to build GCA (Muisyo et al. 2021).17

Eco-Innovation and Green Core Competence
The relationship between proactive environmental strategies, eco-innovations, green core competences, and GCA was investigated using 366 participants from the hotel industry.The results showed that proactive environmental strategies positively affected eco-innovation.This effect was subsequently adjusted toward green core competence and GCA.However, eco-innovation did not affect GCA (Kuo et al. 2021).
18 Environmental Awareness and Green Ambidexterity Innovation Environmental awareness and green ambidexterity innovation positively affected GCA.This concluded that top managers' environmental awarenesses significantly and positively influenced the improvement of GCA by adopting green ambidexterity innovation for polluting companies in China (Cao et al. 2022).
19 Business Analytics, Environmental Orientation, and Green Innovation The mediating role of green innovation in the impact of business analytics and environmental orientation on GCA was explored using 388 participants from Chinese manufacturing companies.This confirmed that business analytics, environmental orientation, and green innovation played essential roles in GCA (Zameer et al. 2022).

20
Green Abilities, Green Motivation, Green Opportunities, and Green Innovation Culture GIC and GRHM practices positively affected GCA.These practices included green abilities, motivation, and opportunities.Green innovation culture also moderated a more substantial influence between GRHM practices and GCA (Muisyo et al. 2022a).

21
Green Organizational Identity, as well as Green Exploitative and Green Exploratory Innovations This article examined the relationship between GOI and GCA, using green exploitative and exploratory innovation (GEI and GER) as mediating variables.The results showed that the ordinary and mediation processes of GOI, GEI, and GER positively influenced GCA (Chen et al. 2022).

22
Corporate Green Strategy, Corporate Green Assets, and Corporate Green Technology This study was conducted on 32 participants in Taiwanese manufacturing companies to determine the relationship between corporate green strategy, assets, and technology with GCA.Based on the results, all the variables positively affected GCA directly or through mediating constructs (Chen 2022).

23
Green Human Resource Management and Enablers of Green Culture This article investigated the patterns by which companies build GCA from GHRM by focusing on the enablers of green culture (EGC), namely leadership emphasis, message credibility, and peer involvement.In this report, GHRM and EGC directly and positively affected GCA, with EGC subsequently mediating the relationship between GHRM and GCA (Muisyo et al. 2022b).

24
Green Marketing Orientation and Green Innovation This study determined the effect of green marketing orientation and innovation on GCA in Batik SMEs, Yogyakarta, Indonesia.The results showed that both factors positively affected GCA (Nuryakin and Maryati 2022).

25
Green Intellectual, Human, Structural, and Relational Capital The effect of green intellectual, human, structural, and relational capital on GCA was determined using 94 participants.From the results, all the utilized factors positively affected GCA, except green human capital (Lastanti and Augustine 2022).
Based on this present review, 5 of the 52 utilized variables did not positively influence GCA.In this case, two of these five variables were unable to increase GCA, namely green absorptive capacity (Lin et al. 2020) and collaborative competence (Widiyati and Murwaningsari 2021).Meanwhile, the remaining three variables, green human capital, business analytics, and eco-innovation, had significant differences.These results indicated that green human capital and eco-innovation increased GCA (Astuti and Datrini 2021;Nivlouei and Khass 2014;Widiyati and Murwaningsari 2021), although they did not have positive and significant effects, respectively (Kuo et al. 2021;Lastanti and Augustine 2022).Business analytics also positively affected GCA (Zameer et al. 2022), although they showcased a negative effect in Widiyati and Murwaningsari (2021).These differences are futuristically interesting for subsequent analysis to provide literacy and additional confirmation for the improvement of the GCA concept.
According to several reviews and Table 3, only two constructs were unable to influence GCA (green absorptive capacity and collaborative competence), with the remaining 50 emphasizing significant elevations.Based on these results, the following was observed: (1) A total of 45 constructs prioritized green innovation, confirming that its implementation provided better organizational competitiveness and positively influenced the achievement of sustainable benefits (Chen 2011).It also indicated that environmental and social responsibility was a crucial capability facilitating the achievement of a sustainable competitive advantage (Hart 1995).Irrespective of these conditions, organizational green innovation still contributed to the company's competitive advantage, which undoubtedly impacted business sustainability.(2) A total of five constructs emphasizing green innovation on intangible assets positively influenced GCA, confirming the perspective of the RBV theory.This focused on the company's internal resources to identify the company assets, capabilities, and competencies having the potential to provide a competitive advantage (Barney 1991).Intangible assets are often known as IC (intellectual capital), which contains three main parts, namely human, structural, and customer capital (Pujianto et al. 2016).This indicated that green intellectual capital improved the company's environmental performance (Yadiati et al. 2019).The management of intangible assets and an environmentally friendly approach also generated more business opportunities, enabling green intellectual capital as a robust framework for promoting organizational sustainability (Benevene et al. 2021).Therefore, the application of green innovation to intangible assets is a strategy used to increase a company's competitive advantage for the maintenance of business sustainability.

Further Research Opportunities
This section presents further research opportunities that the selected articles' authors identified in their research.We found three main areas of interest from two clusters (Table 4).First, replications of studies in different industries or countries were widely suggested by authors.Second, further research opportunities were identified by examining other variables with different data collection methods.Finally, the authors identified the need to analyze the power of moderator and mediator variables influencing the relationship between independent variables and GCA.

Conclusions
This systematic review was conducted with the expectation of ensuring easier access and increased literacy for practitioners and stakeholders.In this process, some analytical performances were used to answer three research questions, where the initial analysis emphasized the upgrading trends and geographic evaluation of GCA.Several reports showed that GCA generated greater global attention a few years after its initial establishment and publication by Chen in 2011.This indicated that the number of scientific articles on GCA had continuously increased since 2019, with significant development subsequently observed in the first quarter of 2022.In this systematic review, 8 of the 25 utilized articles were published in 2022, indicating higher global GCA consideration and increasing environmental concerns.
The second research question prioritized the factors increasing GCA.In this analysis, 50 constructs emphasizing green innovation or environmental management improved GCA, as only 2 variables had no effects, namely green absorptive capacity and collaborative competence.This confirmed that the companies prioritizing green innovation and significant environmental concerns, such as the GCA approach, achieved better performance improvement, adequate competitive advantage, and a sustainable business.According to the definition of GCA, the primary key observed was also green innovation, where 50 of its constructs had significant effects on green competitive advantage.
Regarding the third experimental question, the organizational outcomes obtained during GCA adoption were observed.This indicated that the organizations implementing green innovation and high environmental awareness developed a sustainable business, as well as caused performance improvement and better competitive advantage.This was in line with Chen (2008), where the environmental management used to obtain a green competitive advantage was a business sustainability effort.
When investigating the GCA in various manufacturing industries, strong considerations were highly observed due to several reasons.Firstly, this sector was considered one of the main actors responsible for the environmental issues impacting sustainability.Secondly, the pressure exerted by consumers and stakeholders, as well as the emergence of various environmental regulations, forced the manufacturing industry to switch to a green approach earlier than other business sectors.This research highlights significant theoretical and practical contributions were observed as follows:

1.
This literature review is the first study to present a review on GCA.In addition to a statistical overview, it also provides an in-depth review and future research opportunities.

2.
This literature review led to easier access and increased literacy for scholars, practitioners, and stakeholders, especially on the factors influencing GCA.This allows one to synthesize GCA outcomes to describe better how it affects organizations and the environment.

3.
This review was consistent with the basic assumption of the RBV theory, where companies possessed heterogeneous tangible and intangible resources with unique organizational characteristics.These characteristics subsequently had the potential to be used as organizational GCA sources.

Practical Contributions
1.This review promotes the role of GCA as a framework for corporate sustainability by implementing green innovation and environmental management.

2.
The significant roles of green innovation and environmental management on GCA were considered for practitioners and stakeholders to select organizational GCs (green changes).This is specifically observed in the role of GCA as a framework to promote corporate sustainability.

3.
This literature review provides concrete implications for policymakers in defining the best mechanism for developing green innovation, especially to achieve competitive advantage and business sustainability.

Limitation and Research Agenda
In addition to these contributions, this study has several limitations.Since the literature search was limited to SCOPUS, Web of Science, and Google Scholar publications, indicating that subsequent reports should adopt the GCA-related papers of other data collection sources for broader output.A systematic review was also used in this study to obtain in-depth qualitative insight into GCA's current state and practice from the published literature.Future research can take a more quantitative approach, such as bibliometrics or meta-analysis, to gain insight with a different approach.
Since the great importance of green innovation and the concept of GCA is a framework for promoting organizational sustainability, several future research agendas were proposed.Firstly, future reports should be tested in different contexts, i.e., countries and industries, to generalize conclusions and results.Secondly, subsequent analysis needs to be conducted in non-manufacturing organizations for result generalization, for example, the service industry.Thirdly, different data collection techniques are considered, such as interviews, open-ended questions, and grounded theory approaches.Fourthly, green development should be the main direction of sustainable development regarding the future global economy and society.Based on these descriptions, organizational green innovation and competitive advantage are the problems presently encountered by all companies.In addition, subsequent reports are expected to expand the sample scale and continuously conduct dynamic analyses.The competitive advantage construct is unrelated to green innovation.Therefore, it does not match the GCA definition.
