India’s leading airline, IndiGo has reduced its carbon emissions by 20% in Financial Year FY 2023 with respect to Financial Year FY 2016. Before 2016, the airline was operating an all Airbus A320ceo (Current Engine Option) fleet. Now, only less than 30 such aircraft are left. The airline’s more than 85% fleet constitutes of neo family. Neo means New Engine Option.
IndiGo reduced carbon emissions
With respect to FY 2016, when the airline was operating all ceo fleet, the airline has reduced the carbon emissions by 20%. IndiGo achieved this landmark by upgrading its fleet to more efficient neo family aircraft in the airside operations. On landside ops, the airline has introduced a lot of Electronic Vehicles in its Ground Vehicles fleet.
In the annual report, the airline said that it has invested heavily in deploying Electronic Vehicles (EVs).
The airline carbon emissions stood at 74.6 grams per Available Seat Kilometres (ASKs) in FY 2016. In comparison, now it stands at 59.5 grams per ASK. Available Seat Kilometres (ASK) is a measure of an airline’s capacity calculated by multiplying number of seats by kilometres flown.
SOPs also helped
The airline in the annual report said that In last financial year, the airline had a fleet of 80% Airbus A320neo family jets, which produce less emissions with respect to ceo family aircraft. The airline’s ops team closely monitors the fuel related Standard Operating Procedures (SOPs) and take actions like single engine taxi, variable flap settings and climb/descent profiles. This emphasis on technology and close monitoring helped the airline to lower carbon emissions.
One thing to notice here is Optimum Flap Settings. Recently, The Hindu reported quoting a DGCA official that IndiGo was asking its pilots to carry out Flap 3 landing everytime to save 6 Kgs of Fuel everytime they land. 4 Airbus A321neos of IndiGo experienced tailstrikes within a span of 6 months.
DGCA conducted a special audit at airline’s facility where documentation and SOPs were reviewed. The airline has been slapped with a fine of Rs 30 Lakh as well as an instruction to amend its SOPs in line with DGCA and Airbus FCOM guidelines.
