Flying Green: A Secondary data Analysis on Carbon Reduction Strategies in the Airline Industry

As of 2023, the aviation industry accounts for approximately 2.5% of global energy-related CO₂ emissions, with its total climate impact estimated at around 4% when non-CO₂ effects are included. Following a dramatic drop due to the COVID-19 pandemic, emissions rebounded to nearly 950 million metric tons CO₂—over 90% of pre-pandemic levels. Despite improvements in fuel efficiency, the carbon intensity of jet fuel has not changed significantly, and demand for air travel continues to rise. This study examines the role of Sustainable Aviation Fuel (SAF) in addressing aviation’s climate impact through secondary data analysis. SAF, produced from renewable feedstocks, offers up to 80% lower lifecycle emissions compared to conventional jet fuel. Technological advancements, such as Honeywell’s Ecofining™ process, demonstrate the potential for scalable SAF production and integration into existing fleets. As the industry pursues net-zero emissions by 2050, SAF emerges as a critical transitional strategy, enabling immediate reductions without requiring major infrastructure changes.
