No other area of our organisation provides as large an opportunity to reduce our environmental impact as fuel efficiency, measured in how much fuel is burned to carry a defined number of passengers or a defined weight over a certain distance. An airline’s fuel efficiency is affected by a number of factors, including technology such as aircraft and engine type, maintenance processes such as engine washing, and operational practices such as cruise climbs. Various weight-saving measures such as lightweight cargo containers also play an important role. Our passenger fuel efficiency for 2012-13, as measured in litres/100 passenger kilometres flown, totalled 4.07 L/100PK, an improvement of 1% compared against the previous reporting period of 2011-12. Our overall operational fuel efficiency increased 0.79% year-on-year to 17.705 TK/L. Here we measure weight in tonnes as the zero-fuel weight of the aircraft, i.e. the weight of the aircraft, crew, passengers, and freight, but not the fuel. This incremental improvement is attributed to the introduction of new, more fuel-efficient aircraft, given our already well-developed efforts to reduce fuel consumption and fuel burn.
Emirates’ investment in new aircraft also means our fleet is becoming increasingly quieter. Our A380s are among the quietest large aircraft available, and were designed to meet strict requirements at some of the world’s most noise-sensitive airports. We track our noise performance through a Noise Efficiency Factor, which measures our noise footprint in relation to weight and distance travelled. Our noise factors improved 1% between 2011-12 and 2012-13 as a result of quieter aircraft entering the fleet and the retirement of older, noisier aircraft.
As of 2013, the Emirates’ average fleet age was 6.0 years compared with the IATA average wide-body fleet age of 11.7 years (IATA WATS 57th edition).
We were the first airline to place an order for this efficient twin-deck, and now have more than 47 A380s in service.
Emirates A380 Environmental Facts:
- Larger aircraft mean fewer take-offs and landings (in passenger terms, this would be the equivalent of flying up to seven smaller aircraft types, for certain versions of the Emirates A380).
- The Emirates A380 uses a range of lightweight materials that account for 25% of its structure.
- The A380 is one of the quietest large aircraft, and was designed to meet the strictest airport noise requirements. Emirates has performed highly in the London Heathrow Airport Fly Quiet noise rankings as a result.
- The Engine Alliance GP7200 engines help the A380 comfortably meet ICAO Chapter Four noise standards.
- The Emirates fleet, including A380s, has over 15% better fuel efficiency than the IATA global fleet average (as measured in 2012).
- We continue to work closely with Airbus to further reduce the weight and enhance the fuel efficiency of future A380s.
Emirates Boeing 777
Aircraft from the Boeing 777 family are the workhorses of our fleet, with more than 136 of the long-range, wide-body aircraft currently in service. One variant, the Boeing 777-200LR, holds the world record for the longest non-stop distance ever travelled by a commercial aircraft, achieved on a 22-hour and 42-minute flight from Hong Kong to London.
More than 115 of our Boeing 777s are powered by the General Electric GE90 engine - the biggest jet engine in the world. The GE90 has one of the highest bypass ratios (9:1) in the industry, which means that for every 1 kg of air used to burn fuel in the engine core, 9 kg of air are passed through the fan to provide propulsion. This helps to make it a very fuel efficient engine.
The next generation of Boeing 777s – the 777X – will bring a range of design innovations and new engines to drive greater enhancements in fuel efficiency and noise performance. Emirates placed an order for 150 Boeing 777Xs at the Dubai Air Show in November 2013, laying the foundation for the next phase of our investment in efficiency and environmental performance.
