Abstract: Airports are significant energy consumers within the air transport sector, with energy usage levels comparable to those of small cities. Due to their rapid economic growth and high passenger density, airports emit substantial amounts of carbon and other pollutants. Addressing these challenges involves implementing energy management techniques, adopting green and alternative energy sources, and utilizing AI and data-driven systems to monitor and control energy consumption. This article explores sustainability in the energy sector, focusing on sustainable practices at green airports. Emphasizing environmental sustainability, it examines key parameters such as energy-saving measures, water consumption management, renewable energy sources, electric vehicles, automation systems, and AI-driven energy control. Sustainable solutions can reduce harmful emissions by 50 %. This review compares sustainability initiatives across various airports, presents the airport carbon accreditation program, and evaluates business systems using aviation industry publications. The findings indicate that carbon trading programs and other sustainable strategies can significantly mitigate the environmental impact of airports, contributing to a greener and more sustainable future for the aviation industry.
