This research aims to identify the role of governance in improving environmental performance by applying it to the civil aviation sector by achieving a set of sub-objectives, including highlighting the role and importance of governance in improving environmental performance and creating value, identifying the mechanisms available to embody good governance within the civil aviation sector. The research deals with presenting previous experiences through which researchers worked hard to crystallize governance concepts and improve environmental performance, and attempts to highlight the challenges and obstacles facing the application of governance principles that could affect the effectiveness of environmental performance, and define a vision for future directions to enhance the role of governance in improving environmental performance in the sector. Aviation, enabling leaders in the aviation sector to use governance tools and practices efficiently and effectively. The inductive approach was used in addition to the descriptive analytical approach, which is defined as a method of research that deals with existing events, phenomena, and practices that are available for study and measurement as they are without the researcher's intervention in their course. The researcher can interact with them, describe them, and then analyze them to demonstrate the role of governance in improving environmental performance to achieve Research objectives: The survey list was the means of collecting data, and the study population may consist of some workers in the civil aviation sector. The data was also transcribed and statistically analyzed using a computer through the Statistical Package for Social Sciences (SPSS V. 25) program. The results showed a failure to conduct a periodic evaluation of environmental performance and identify opportunities for improvement, a failure to conduct periodic evaluations of the effectiveness of strategies to improve environmental performance within the organization, a failure to expand the training programs and workshops necessary for employees to improve their environmental performance, as well as proving the validity of the main hypothesis and sub-hypotheses. The researchers recommended many recommendations, the most important of which are for the institution to conduct a periodic evaluation of its environmental performance in a way that contributes to accurately identifying opportunities for improvement to enhance them and identifying and evaluating potential environmental risks, conducting a periodic evaluation of the effectiveness of strategies to improve environmental performance, enhancing environmental awareness and paying attention to training on correct environmental practices.
