Advancing collaboration toward green supplier selection: perspective of green relational capital

PurposeThough there is literature on green collaboration to supplier selections, there are hardly any empirical studies that analyze collaborative networks toward green supplier selection (GSS) from the perspective of green relational capital (GRC). Therefore, this study aims to fill this research gap by analyzing the development of collaboration toward GSS through the lenses of GRC. Also, this study explores how collaboration between institutions and their relevant green stakeholders, framed through the lens of GRC influences the selection of green suppliers.Design/methodology/approachThis study uses an exploratory case study approach involving public universities in Ghana. This study is based on interviews conducted with 27 key respondents across seven universities. A purposive sampling technique was used in selecting respondents who were interviewed face-to-face with a semi-structured interview guide. Atlas ti software was used to generate themes for discussion.FindingsThis study's findings suggest that the reason green criteria are not integrated into supplier selection is due to an insufficient collaboration among relevant green stakeholders. Through green training workshops, conferences, continuous professional development and affiliation with professional bodies, procurement practitioners can develop a collaborative network among themselves to promote the integration of green sustainability into supplier selection. Constructs that help to establish strong collaborative network identified in this study include trust and consistency, mutual benefits, obvious intentions and effective communication.Practical implicationsThis study identified constructs promoting effective green collaboration toward the adoption of GSS. These constructs as identified in this study, provide a clear means of developing green collaboration among relevant stakeholders. By fostering and developing collaboration, the main construct of GRC, institutions can successfully integrate green sustainability into their supplier selection process, leading to long-term benefits for both the environment and the institution.Social implicationsCollaboration toward integration of green sustainability into supplier selection necessitates engagement with various relevant green stakeholders, including suppliers, customers, government bodies, colleagues in sister institutions and environmental advocacy groups. This fosters a sense of shared responsibility and collective action toward sustainability goals.Originality/valueThis study offers empirical evidence on the impact of collaboration on supplier selection and green sustainability performance, contributing to the existing body of literature. By analyzing collaboration, a perspective of GRC, toward the integration of green sustainability into supplier selection is considered as a novel study.
