The aviation industry is among the most energy-intensive, producing about 2.5% of total CO₂ emissions worldwide. As demand for air travel continues to grow and airports as major energy consumers and infrastructure hubs continue to develop, the role of green airports is increasingly evident. Green airports are transforming aviation infrastructure through renewable energy systems, sustainable technology, and intelligent and rational waste management systems. This paper investigates the innovations in sustainability that have the potential to contemporize airport operations, including the application of renewable energy deployment systems, smart waste systems, and digital technologies that reduce environmental footprint. This paper employs global and India examples to highlight best practices, policy enablers, and challenges as traditional airports transition to sustainable airports that are ready for the future.
