The document discusses various strategies that IndiGo airline can implement to reduce its environmental impact and improve sustainability. In the short term, it suggests maximizing aircraft utilization, introducing unbundled ticket pricing, and implementing e-ticketing. Long term strategies include using biofuels, installing wingtip devices to reduce fuel consumption, starting a carbon offset program, and replacing older aircraft with more fuel efficient models. It also discusses strategies for finance, people management, and driving change within the organization to further sustainability goals.

2. Alignment with COP21 and INDC
• As per the recently concluded Paris Conference on climate
change, 195 nations have agreed to limit global warming to
below 2 degrees Celsius over pre-Industrial Revolution levels
and try for 1.5 degree if possible.
• The Government of India is promoting greater use of
renewables such as Solar energy, Wind energy, Hydro energy,
Biomass and Alternate fuels as per its INDC report.

3. Airline Industry affecting the climate
It accounts for four to nine per cent of the total climate change impact of
human activity.
since 1990, CO2 emissions from international aviation have increased 83
per cent
United Airways has already started using farm waste as alternate fuels
in short distance flights
IndiGo can become the first Indian carrier to follow United Airways and
use alternate fuel
Using Biofuels can reduce the overall cost of fuel and the benefits can be
passed on to the customers.

4. Continuous Descent Method
• Instead of beginning the descent 17 kilometres away, the crew began their descents some 70
kilometres away and from a height of 11,000 feet, while maintaining an angle of descent of 3° and
keeping engine power changes to a minimum.
• The teams measured the results with 14 microphones placed in neighbourhoods near the airport
and found that compared with conventional 767 approaches, the noise dropped by between 3.9
and 6.5 decibels. That is a drop in acoustic energy of more than half, and is noticeable to the
human ear.
• This manoeuvre also saved nearly 200 kilograms of fuel on each landing.
Technology and Operations

5. RNP SYSTEM
• Indigo has collaborated with Quovadis, a subsidiary of Airbus, the Airports Authority of
India (AAI), and the Directorate-General of Civil Aviation (DGCA) to put in place required
navigation performance (RNP) approach in regular airline operations
• The RNP procedure brings great benefits to both the authorities and the airline and a
shorter flight path, saving 75 Km on each approach, which is approximately 400 Kg of fuel
saving per landing and a corresponding amount of reduction of greenhouse gas emissions

6. Strategies to be Implemented
Short term startegies-
• Fast turn around to maximize aircraft use
• Introducing Unbundled pricing structure
• Implementing complete E-Ticketing system
• Recycle and reuse of various products like toilet paper, paper
cups, water bottles and beverage cans etc. in order to control
cost
• Regular wash of engines and other peripheral

7. Long term strategies-
• Use of alternate source of fuel like Bio fuel
• Installing Scimitar winglets
• Start a carbon offset programme
• Use ground power units instead of auxiliary power units when
grounded
• Replace papers and magazines with tablets in order to seize weight
• Engine modification and upgradation to more fuel efficient aircrafts
• Implementation of advanced hybrid electrical engine by Cogar
International Energy Corporation

8. Finance
• Indigo made a net profit of Rs. 1,308 crores in FY
2014-15.
• It also raised Rs. 3,018 crores in the recently
concluded IPO.
• Indigo should judiciously use this money in R&D,
buying new fuel-efficient aircrafts and installing
Scimitar winglets to improve their fuel efficiency and
reduce costs.

9. People
• Work from home compressed work week and
flexitime options should be implemented
• Amenities like gym, pharmacy, café and ATM’s should
be available inside the premises
• Start a training school for lower level employees

10. Change Management
• Remove food that is majorly wasted by the
customers (American Airlines)
• Remove company logo from trash bags (Southwest)
• Install lighter and thinner seats (United Airlines)
• Lay thin carpets
• Hire female cabin crew (Go Air)
• Advertisements
• Lighter food and beverage trolley and trash bins
• Order aircrafts with smaller lavatories
• Ditch life jackets on over land flights (Qantas)
• Descaling toilet pipes regularly (British Airways)

11. Fuel accounts for 1/3rd of the airline’s
cost and every kilo shed reduces $100
from an aircraft’s annual fuel bill.
