Indira Gandhi International airport here has become the fifth airport in the Asia-Pacific region to receive accreditation for its efforts in managing and reducing carbon emissions. A global body of airports, Airport Council International (ACI), has accredited the IGI airport at Level 2 – 'Reduction' under the Airport Carbon Accreditation programme.

The IGI airport, operated by GMR-led consortium Delhi International Airport Limited (DIAL), has become the second
airport in India after Bangalore International Airport to be accredited at this level.
Airport Carbon Accreditation is an institutionally endorsed programme that independently assesses and recognises
airports' efforts to manage and reduce their carbon emissions.
