With the adoption/diffusion of clean technologies, it is possible to reach most of the required amount of emission reduction to address climate change. In this regard, identifying its variables and understanding the adoption process deeply will help to accelerate clean technology adoption (CTA) and develop effective policies and strategies on clean technologies. The aim of this study is to determine the CTA process through a new model based on the Technology-Organization-Environment Framework (TOE) applied to mineral products industry in Turkey. The results revealed that the CTA is considerably affected by technological and organizational factors but not by external environmental factor. Among these factors, complexity, relative advantage and compatibility of the technology, human resource quality and firm vision are listed as key. In addition, the results showed a difference between CTA levels in terms of technological and organizational factors, and CTA is positively affected by the level of R&D activities of the firm.
