The IATA Technology Roadmap provides an overview and assessment of technology opportunities for future aircraft, including improved engine efficiency, aerodynamics, lightweight materials, and structures as well as radical new configurations and propulsion systems. Furthermore, the benefits of these technologies for aviation emissions are estimated on a world-fleet scale, and the effects of new aircraft developments under changing market conditions are considered.

The IATA Technology Roadmap was created with external support from the German Aerospace Centre (DLR), with contributions from other partners from industry and research organizations. 
Note: the technology roadmap will be updated in 2023

Technology delivers results for climate action

Amongst the four pillars (technology, operations, infrastructure, economic measures) of aviation's strategy to achieve net-zero carbon emissions by 2050, technology and sustainable aviation fuels (SAF) collectively deliver the highest improvement benefits.
