Modeling the impact of green supply chain practices on environmental performance: the mediating role of ecocentricity

Abstract

PurposeThis study aims to examine the relationship between green supply chain management (Green SCM) practices and environmental performance, and develop an integrated model to explain the mediating role of ecocentricity on the relationship between Green SCM practices and environmental performance in the context of the Ghanaian downstream petroleum industry.Design/methodology/approachTo address the objectives of the study, a survey had been conducted among companies in the Ghanaian downstream value chain. The paper used the structural equation modeling approach and smart partial least squares (Smart-PLS) analytical tool.FindingsThe study revealed that Green SCM practices had a significant and positive relationship with supply chain ecocentricity and environmental performance. The study further revealed that supply chain ecocentricity significantly mediated the relationship between Green SCM practices and environmental performance.Practical implicationsThe study has developed a new integrated model to enhance oil and gas marketing and distribution company's adaptation and implementation of Green SCM practices.Originality/valueThe study had successfully applied the natural resource-based view and the stakeholder theory in the context of Ghana's downstream petroleum industry. Specifically, these theories had been integrated to form a new model to explain the relationship between Green SCM practices, supply chain ecocentricity and environmental performance in the context of Ghana's downstream petroleum industry. The newly developed integrated model has wider predictability as compared to the individual theories.

Implications of sustainability initiatives on African Continental Free Trade adoption by firms under environmental uncertainty

“…All the constructs and sub-constructs institutionalization (coercive regulatory, normative and mimic), SCI (internal, customer and suppliers), SCR (reflexibility, robustness, agility), innovativeness (willingness to try and creative original) in the paper have been retrieved from literature and validated for the current use (Aray et al , 2021). For instance, sustainability initiative constructs such as institutionalization, SCI and innovativeness were retrieved from, SSC performance measure were retrieved from (Appiah et al , 2021a, 2021b, 2022a, 2022b, 2022c) and validated, environmental uncertainty (Foss et al , 2019) measure were retrieved from and validated and finally, SCR (Wang et al , 2020) measure were retrieved from and validated. Copy of the survey instruments have been attached to the paper (refer to Table A1 in Appendix).…”

“…These beliefs are known as research philosophy, and it is among the basis through which data collection and analytical approaches can be identify to complete a research work. The outcomes of the data that would be collected either through primary or secondary approach will yield a novel knowledge to help expand the research scope of a certain field of interest (Saunders et al, 2012;Zikmund et al, 2012;Appiah et al, 2021aAppiah et al, , 2021bAppiah et al, , 2022aAppiah et al, , 2022bAppiah et al, , 2022c. In short, addressing research philosophy entails creating awareness and formulating beliefs and assumptions that seek to answer a research topic.…”

“…This implies for all the other situational constructs to be effective determinants in the African free trade area, there should be AfCFTA adoption first and foremost. The new continental trade pact offers a unique opportunity for countries in the region to integrate competitively into the global economy, reduce poverty and promote inclusiveness (Köksal et al, 2017;World Bank, 2022;Appiah et al, 2021aAppiah et al, , 2021bAppiah et al, , 2022aAppiah et al, , 2022bAppiah et al, , 2022c. The pact is expected to create job opportunities, innovation, human development and drastically reduce the over reliance on external support for development.…”

“…ECOWAS like any other regional market in Africa has not achieved much of its expectations. This continues to create environmental uncertainty for new entrants for AfCFTA (World Bank, 2022;Appiah et al, 2021aAppiah et al, , 2021bAppiah et al, , 2022aAppiah et al, , 2022bAppiah et al, , 2022c. According to Foss et al (2019), a situation is described as uncertain if there are no objective probabilities associated with the possible outcomes and the probability of the event occurring is unknown.…”

“…This trend is confirmed by the growing body of research on sustainable supply chains (SSCs) in recent years. The transition to SSCs in emerging economies is characterized by a number of factors related to business development and the characteristics of the economic, political and social environment (Aray et al, 2021;Appiah et al, 2021aAppiah et al, , 2021bAppiah et al, , 2022aAppiah et al, , 2022bAppiah et al, , 2022c. Despite a growing body of research on SSC, there is a paucity of theoretical studies and empirical evidence on SSC in developing and emerging economies, which makes SSC research in emerging economies interesting and valuable.…”
