Measurement and improvement of airport’s environmental behavior: an empirical study from North African Countries (NAC)Eid, Ahmed (Avtor) Obrecht, Matevž (Mentor) Barakat, Mahmoud (Komentor) environmental sustainabilityairportenvironmental sustainability performanceenvironmental knowledgeenvironmental behaviorEnvironmental challenges have grown in worldwide relevance. Considering that most environmental issues are due to human behavior, it is crucial to be aware of environmental sustainability issues in airports where many environmental problems arise. It is worth noting that, in the global society of the 21st century, air transportation serves an important purpose as one of the logistics operations (a crucial component of the worldwide economic supply chain). Otherwise, the aviation sector is one of the factors that contribute to the degradation of the environment. Thus, environmental sustainability in airports is essential, as it is associated with conserving the airport environment from degradation. Since human actions create most environmental problems, fostering eco-friendly habits is seen as a viable strategy for a sustainable future. Hence, enforcing environmentally friendly behavior is vital to achieving environmental sustainability, considering the governing authorities' continuous and rising demand for transportation system sustainability. Thus, under the lances of reasoned action theory, the research aim is to improve the airport's environmental sustainability by developing a new model to develop specific stakeholders' environmental behavior, as environmental sustainability has become a pledge of every supply chain member. Investigating airport individuals' environmental behavior by measuring the impact of airport environmental knowledge and the airport's environmental sustainability performance on their environmental behavior through attitude and testing the moderating role of environmental advertising on the indirect effect of environmental sustainability performance and environmental sustainability knowledge. Notably, the research is based on the reasoned action theory since it concerns the motivation for behavior. The research contributes to extending the reasoned action theory since it strives to adopt the theory in North African airports. Moreover, this research would contribute to expanding the reasoned action theory by providing a theoretical model for understanding its abstract concepts by examining the impact of environmental sustainability knowledge, performance, attitude, and advertising on developing environmental behavior.
