Notes: Indira Gandhi International Airport in Delhi achieved Net Zero Carbon Emission Airport status, the first in India. This Level 5 certification recognizes the airport's success in maintaining a net zero carbon balance. The airport reduced 90% of Scope 1 and Scope 2 emissions and offset the rest. Originally aiming for net zero by 2030, it met the goal earlier through renewable energy, electric vehicles, zero waste programs, and green infrastructure. The airport now aims to achieve net zero in Scope 3 emissions by 2050.
