As air transportation continues to play a critical role in global connectivity, the need for sustainable practices in the aviation industry has never been more urgent. India is making significant strides toward environmental responsibility, particularly through the development and management of its airports. Here are some examples explaining how:

Cochin International Airport (COK), Kochi Cochin International Airport, Kerala, is a pioneering example of sustainability, being the world's first fully solar-powered airport. It meets all its energy needs through solar power, earning the prestigious Champions of Earth award from the United Nations in 2018.

Indira Gandhi International Airport (DEL), Delhi Delhi's IGI Airport has achieved Level III accreditation under the Airport Carbon Accreditation programme. The airport has implemented various energy-efficient practices, including the use of renewable energy sources and effective waste management systems.

Chhatrapati Shivaji Maharaj International Airport (BOM), Mumbai Mumbai's international airport has also attained Level III accreditation, showcasing its commitment to reducing greenhouse gas emissions. Initiatives include extensive water conservation measures and energy-efficient technologies throughout the facility.

Kempegowda International Airport (BLR), Bengaluru This airport is recognised for its sustainable practices, earning Level III accreditation as well. It has invested in rainwater harvesting systems and solar energy projects to reduce its environmental footprint.

The role of the Airports Authority of India (AAI) The Airports Authority of India (AAI) oversees the management of numerous airports, focusing on integrating sustainability into their operations. AAI manages 125 airports, implementing green practices to enhance energy efficiency and minimise environmental impact.

Government initiatives for environmental responsibility The Government of India has recognised the importance of sustainability in aviation. The Directorate General of Civil Aviation (DGCA) has established guidelines for monitoring noise and emissions, and an Aviation Environmental Unit has been set up to address these critical issues.

As passenger traffic in India is projected to grow significantly, sustainable airport development remains a priority. The Ministry of Civil Aviation (MoCA) is promoting the construction of new Greenfield airports designed for carbon neutrality from the outset, ensuring that the expansion of India’s aviation sector aligns with global sustainability goals.
