Reducing Emissions through Operational Efficiency

Capt. Russell Davie

Cathay Pacific Airways

Current Practices Include


  • Monitoring fuel used on a sector by sector basis.

  • Monitoring individual aircraft performance.

  • Minimize additional fuel uplift by crews, through a robust and transparent fuel policy.

  • Ensuring aircraft and engines and airframes are maintained to the highest possible standard.

Why the focus on Operational Efficiency?

  • Fuel is a significant part of the airlines budget, nominally around 35%

  • Fuel savings directly affect the profit margin in a marginal profit industry.

  • Importantly in today’s environmentally aware world, the Environmental Impact of flight operations is reduced.

Environmental impact

  • Environmental impact of flight operations, particularly CO2 emissions, is directly proportional to the fuel used.

  • Any fuel saved, directly reduces the impact of flight operations on the environment.

  • Primarily cost saving measure, as fuel represents a very significant proportion of any airline budget .

ATC Restrictions

  • Many ATC Route structures still based on 1960s technologies

  • Limited and restricted by political boundaries

  • Military ownership of significant airspace, which is often little used.

Fuel Tankering

  • Airlines tanker fuel due high differentials in fuel price across their networks. There is a significant cost involved in adoption of a “No Tankering” policy, equating to millions of US$/year for a major carrier.

  • The cost of tankering in environmental grounds is between 3.2 - 4.5% for every hour of flight.

Reasons Behind Fuel Price


  • Cartel. Market share is divided between suppliers and therefore price controlled.

  • Import pricing parity. Government will charge you a premium to make the cost of your import the same as the locally supplied product.

  • Government controlled monopolies.


  • New Generation Aircraft and Engines will provide an improvement over the next few years.

  • Advanced ATC systems should permit more efficient routes and more optimal flight levels to be flown by a higher percentage of aircraft than today.

Alternate Fuels

  • Fuel specification has to be compatible with current engines.

  • Must be widely available, or, able to admix with current fuel specifications.

  • More environmentally friendly.

  • Cost should be at least equal to current fuel.

  • Availability in the near future unlikely.

Barriers to progress

  • Investment in new aircraft is extremely capital intensive, not all airlines can afford to invest in a fleet renewal program.

  • New engine technology reduces total fuel used per passenger Km, and therefore CO2, however it has little impact on NOx during the Landing/Take-Off cycle.

  • Inefficient ATC systems and procedures, particularly across international borders, is currently the single largest cause of fuel wastage in aviation.


  • Urgent work required to improve air traffic procedures and route efficiency. This is the area where largest gains can be achieved in a relatively short timeframe.

  • Reduce or eliminate reasons for tankering fuel. Reduction or even elimination of local price differentials will create a step improvement in the total fuel used by the industry.

  • These issues must be largely Government led initiatives.


  • Airlines investment in new equipment will reduce emissions per passenger Km, but is not the complete solution.

  • Alternative fuels, while not available in the near future, they are beginning to develop in a promising manner.

  • Airlines already operate as efficiently as they are able, as this has a direct bearing on costs.
