Fact Sheet: Technology Roadmap for Environmental Improvement

  • The IATA Technology Roadmap gives an overview of current and future technologies that can reduce the carbon footprint of aviation. 
  • It analyses the potential carbon reduction benefits of new technologies for airframes, engines and air traffic management as well as alternative fuels.
  • The Roadmap considers short-term solutions such as retrofits as well as longer-term developments that can only be implemented in new aircraft designs.
  • It identifies approximately 30% improvement in fuel efficiency per aircraft by 2020

Results of the study show the following carbon savings per plane

Timelines and examples of technologies Total Impact
Retrofits 7 to 13%
  • Winglets mounted on the wingtips of aircraft reduce fuel burn with improved aerodynamics
  • Engine components replaced by more advanced ones for better combustion and airflow
  • Cabin retrofits with lighter materials for furnishing and less energy-consuming lighting and in-flight entertainment
 
Production Updates 7 to 18%
  • More airframe structure components made of lightweight composite material instead of aluminium
  • Advanced engines for current aircraft production series
 
New aircraft design before 2020 25 to 35%
  • Geared turbofan engine will reduce fuel burn by 10 to 15%
  • Open rotor engine will reduce fuel burn around 25%
  • Counter-rotating fan will reduce fuel burn 10 to 15%
  • Advanced turbofan will reduce fuel burn around 15% 
  • Laminar flow reduces aerodynamic drag by reducing turbulence on aircraft surface, 10 to 15% less fuel burn
 
New aircraft design after 2020 25 to 50%
  • Blended wing body, rather than classical tube & wing architecture
  • Revolutionary engine architectures
  • Fuel cell system for on-board energy
