Sustainable airports are emerging as a beacon of hope as nations across the globe intensify their efforts to achieve their climate targets. These airports prioritize the use of renewable energy sources, such as solar and wind power, and energy-efficient technologies to optimize energy consumption. To become sustainable, airports require advanced technologies, automation, and digitalization across all their operations, which as a corollary improves efficiency, safety, and passenger experience, and reduces carbon emissions.
These advancements have ushered in the age of Airport 4.0. Leading the charge in building green airports are some of the world’s most progressive aviation hubs, including Helsinki Airport in Finland, Indira Gandhi International Airport in India, Changi Airport in Singapore, and the San Francisco International Airport in the USA. India is gradually taking the lead in sustainable airport development, with most airports progressing towards becoming carbon-neutral by December 2024 and achieving net-zero emissions by 2030.
