The aviation industry, known as one of the hardest sectors to decarbonise, has embarked on a mission to achieve net zero emissions by 2050. With an estimated cost ranging between $4.7 trillion and $5 trillion, this endeavor involves improving aircraft efficiency, adopting sustainable aviation fuel (SAF) made from renewable sources, exploring hydrogen and electric-powered flight, and implementing carbon offsetting strategies. Aircraft leasing companies play a crucial role by facilitating the transition to newer, more fuel-efficient fleets and engaging in sustainability initiatives. The push for SAF, projected to constitute a significant portion of fuel demand by 2050, faces challenges in supply limitations and cost considerations. The debate around the most viable decarbonisation paths includes viewpoints on the role of SAF versus e-fuel, synthetic fuel derived from captured carbon and green hydrogen. While some advocate for a more cost-effective approach of environmental levies and support for carbon capture projects, others emphasize the need for visible industry-led solutions like scaling SAF. The uncertainty in technology readiness and market size, with jet fuel being a relatively modest industry compared to tech giants, pose challenges for investors and necessitate government support to drive scale. In parallel, the industry explores innovative technologies to immediately reduce fuel consumption through pilot behavior adjustments and contrail mitigation. These scalable solutions provide an interim bridge while SAF production and other decarbonisation efforts mature. The road to sustainable aviation demands collaborative efforts, financial backing, and technological advancements to navigate the complex landscape and achieve ambitious emission reduction targets.
