The rapid economic, cultural and industrial development, and population growth in Saudi Arabia has created environmental challenges, threat of energy, resource crisis, and climate change. One of the contributing factors is the increasing number of manufacturers and lack of green practices. Therefore, this study aims to investigate the aspects that influence implementation of Cleaner Production Principles by Saudi Plastic Manufacturers. A conceptual model that was based on technological, environmental, and organizational theory was used to present the primary motivating factors of manufacturers in Jeddah for pollution reduction and also to the achievement of sustainable development goals according to Saudi Vision 2030. The research model provides motivations for the environmental and economic consequence of Cleaner Production Principles Implementation. This work is grounded in hypothesis; such as, regulatory and customer pressures having a positive influence on the implementation of CP principles in the Saudi plastic manufacturer industries. A questionnaire on the implementation of CP principles was provided to the manufacturers. 127 samples were analyzed through SPSS to investigate the relationship between the independent (CP Principles implementation) and dependent variables (motivational factors for implementation). The results have indicated that Regulatory Pressure and Customer Pressure has significant positive influences on the implementation of CP Principles for Saudi manufacturers. The quality of HR, SM support, governmental support, and environmental uncertainty have significant negative influences on the implementation of CP principles. The lack of previous research about CP implementation in KSA will make the results of this research beneficial for future researchers and practitioners.
