Background: Nurse managers' sustainable management behaviors assist nurses in realizing 
their own capacity to shape their consciousness of sustainable development and have an 
impact on the global concerns posed by climate change for the expansion and improvement 
of any healthcare organization. Aim of the study: To assess the role of nurse managers' 
sustainable management behaviors in building sustainability consciousness among nurses. 
Research design: A descriptive-correlational research design was applied. Subjects: This 
study involved all nurse managers (n= 41) and a stratified proportional randomized sampling 
of nurses (n=286) who were working at Tanta University International Teaching Hospital in 
all departments and intensive care units. Tools: Two tools for data collection were used: the 
Sustainable Management Behaviors Scale (SMBS) and the Sustainability Consciousness 
Questionnaire (SCQ). Results: Slightly more than sixty percent (65.9%) of nurse managers 
had a high-level of sustainable management behaviors, and around half (52.1%) of nurses had 
a high level of sustainability consciousness. Conclusion: The current study showed a 
significant positive statistical correlation between nurse managers' overall sustainable 
management behaviors and nurses' sustainability consciousness. Recommendations:
Establish educational programs about sustainable management behaviors to provide nurse 
managers with needed knowledge and skills, develop green leadership, increase sustainable 
performance, and create a sustainable nursing workforce.
