IATA Details Roadmap to Net-Zero Emissions by 2050

The International Air Transport Association (IATA) has released the "Aviation Net Zero CO2 Transition Pathways Comparative Review," a resource aimed at providing insights into achieving net-zero carbon emissions by 2050. 

Developed in collaboration with institutions such as the University College London (UCL), the Air Transport Action Group (ATAG), the International Council on Clean Transportation (ICCT), and the Mission Possible Partnership (MPP), this report evaluates 14 leading roadmaps for the transition.

One significant finding highlighted in the analysis is the variability in the role of Sustainable Aviation Fuels (SAF) in aviation decarbonization. According to the report, SAF's contribution ranges from 24% to 70%, with a median value of 53%. This wide range reflects uncertainties regarding factors such as government action, investments, production costs, and access to raw materials.

"To achieve zero CO2 emissions by 2050, almost all global roadmaps suggest that the aviation sector will need help from market-based measures and carbon removals to address residual emissions in 2050," said Marie Owens Thomsen, Senior Vice President of Sustainability and Chief Economist, IATA.

Thomsen stressed that without such support, none of the roadmap scenarios would lead to zero carbon emissions by 2050.

Additionally, the report highlights the significance of technological advancements and operational efficiencies in achieving emissions reduction. These factors are projected to contribute to approximately 30% of emissions reduction by 2050 across all scenarios.

While hydrogen and battery-powered aircraft are anticipated to play a vital role in emissions reduction, their effectiveness will depend on policy implementations and the evolution of renewable energy prices.
