Mega infrastructure projects and their contribution to sustainable development: the case of the Athens Metro

This paper examines the critical role of Mega Infrastructure Projects in sustainable urban and peripheral development by presenting a Sustainable Infrastructure Serum Analysis supported by primary field research. In the Athens Metro case study, we examined the project's impact on sustainable development by analysing the opinions of the project's users. As a result, the Athens Metro serves as a case study to help us better understand sustainable infrastructure as a framework for green growth from the standpoint of society. The three pillars of sustainable development are inextricably linked. This study focuses on the social comprehension and acceptance of a Mega Infrastructure Project effects. We attempt to demonstrate the interdependence of the three pillars of sustainable development through public opinion responses to our research by developing a statistical model fed by public responses to a prototype questionnaire that we developed to support our research objectives. The study's findings highlighted the project's social acceptability and necessity by establishing a direct positive correlation between sustainability, society, the economy, and the environment from the standpoint of society.
