Why be energy efficient?

The air transport industry has been focused on fuel efficiency improvements for decades, as fuel use can constitute between 20–35% of operating costs. 

Even though significant progress has been made, the potential to improve fuel efficiency by as much as 50% by 2050 still exists, through further improvements in weight reduction, aerodynamics, engine efficiency, use of alternative fuels and the upgrade of fleets. Improving fuel efficiency also provides the lowest cost strategy to achieve greenhouse gas emission reductions. Therefore, the business case for investing in fuel efficiency in the air transport sector remains a key business driver.

Ways to save

The International Aviation Transport Association (IATA) Technology Roadmap Report found that between now and 2020 there are key energy efficiency opportunities. See Ways to save – Air transport for more information.
