A weak organizational culture creates an environment that leads to inefficiencies in human resources. Both a weak organizational culture and inefficiencies in human resources are major barriers to the implementation of environmental action processes. However, very few studies have been published in this area. The objective of this study, therefore, is to conduct an exploratory case analysis and develop some proposals based on the conclusions arrived at. We have analyzed a total of 8 factories to ensure a sufficient number of sources of information. Some factors linked to organizational culture and the human resource management in a factory that favour environmental performance were found.
