In a bid to combat climate change, airlines and aircraft manufacturers have pledged to achieve net-zero carbon dioxide emissions by 2050, as the commercial aviation sector is anticipated to grow substantially. However, a study analyzing manufacturer delivery projections raises concerns about meeting the 2050 target. The research forecasts that the 2023 global fleet and new aircraft deliveries up to 2042 could collectively emit nearly half of the net-zero carbon budget, emphasizing the urgency for emissions reductions. To align with climate objectives, all new aircraft delivered by the mid-2030s must have zero net CO2 emissions during their operational lifetimes. The study also highlights a potential market for 10,000 new aircraft powered by hydrogen, electricity, or sustainable aviation fuels. To meet the net-zero CO2 goal, manufacturers are advised to invest in zero-emission aircraft, particularly emphasizing the development of hydrogen-powered planes and ensuring the capability for 100% SAF use by 2030. Furthermore, setting ambitious emissions targets across the value chain is crucial to minimize CO2 output over the aircrafts' lifetimes, signaling a necessary shift towards sustainable aviation practices.
