Green procurement is the integration of both environmental and social elements with traditional procurement practices. Green procurement is truly the pressing call of the day and has recently gained attention of both researchers and supply chain practitioners globally. However, there are scant research studies available in the direction of unethical practices and its influence on key green procurement variables. The aim of the current study is to explore the relationships between buyer-deceitful practices, buyer-subtle practices, buyer-supplier relationships, supplier development, and green design. Here, SPSS AMOS version 24.0 has been used to simultaneously assess the measurement instrument and hypothesized model. The findings show that relationship between buyer deceitful activities and supplier development is significant. Secondly, relationship between buyer-supplier relationship and green design is also found to be strong. The study provides some unique contributions to the theory and further extends the knowledge base.
