The International Air Transport Association (IATA) unveiled a series of roadmaps to provide step-by-step detailing of critical actions and dependencies for aviation to achieve net zero carbon emissions by 2050.
These roadmaps address aircraft technology, energy infrastructure, operations, finance, and policy considerations leading to net zero.
By adopting a Long Term Aspirational Goal (LTAG) at ICAO’s 41st Assembly, governments and industry are aligned to reach the same net zero CO2 emissions goal by 2050. As policy initiatives lay the foundation for many needed innovations and actions, these roadmaps will be a critical reference point for policymakers.
“The roadmaps are the first detailed assessment of the key steps necessary to accelerate the transition to net zero by 2050. Together, they show a clear direction and will evolve as we dig deeper to set interim milestones on the way to net zero. I must emphasize that roadmaps are not just for airlines. Governments, suppliers, and financiers cannot be spectators in aviation’s decarbonization journey. They have skin in the game. The roadmaps are a call to action for all aviation’s stakeholders to deliver the tools needed to make this fundamental transformation of aviation a success with policies and products fit for a net-zero world,” said Willie Walsh, IATA’s Director General.
The roadmaps were not developed in isolation. A peer-to-peer review, complemented by a modeling tool provided by the Air Transportation Systems Laboratory at University College London (UCL), was conducted to calculate emission reductions for each technology.
Highlights of each roadmap include:
The challenges to ramp up SAF production are a good illustration of the importance of these roadmaps. As a drop-in solution, SAF is expected to deliver about 62% of carbon mitigation needed to achieve net zero by 2050. But even though SAF is expected to be fully implementable with future aircraft fleets, it still has major inter-dependencies on policy, aircraft technology, energy infrastructure, financing, and operations for which these roadmaps are critical.
“The roadmaps show where all stakeholders should focus their efforts. There are two certainties. By 2050 we need to be at net zero carbon emissions. And the steps to get there that are outlined in these roadmaps will evolve as the industry’s expertise grows. The policy is particularly important early on as it largely sets the scene for private sector investors to move. With that, the private sector can decarbonize at scale and speed,” said Marie Owens Thomsen, SVP of Sustainability and Chief Economist at IATA.
“Without the right policy incentives and bold investments, many of the technologies and innovations simply won’t happen at scale. Everything is related, and that is why we have the five roadmaps to tie all the parallel elements together and give our stakeholders, including governments, a complete understanding of everything that needs to happen,” said Owens Thomsen.
“Time is of the essence, as highlighted by these roadmaps. Immediate action is required to commercialize scalable zero-carbon energy storage solutions along with the required infrastructure and to build a business case for their rapid delivery at Gigawatt scale,” said Prof. Andreas Schafer, Director of UCL’s Air Transport Systems Laboratory.
