Decarbonizing aviation: A 2050 mirage?

Aviation significantly contributes to global carbon emissions, accounting for 2.5% of total CO₂ emissions. With air traffic increasing by approximately 3.8% per year, this figure is expected to rise unless decisive action is taken. Beyond direct CO₂ emissions, aviation also produces non-CO₂ effects, such as condensation trails and nitrogen oxides (NOx), further contributing to climate change. Achieving net-zero CO₂ emissions by 2050 requires a combination of technological advancements, policy measures, and industry-wide collaboration.

This report, written by Elsie Nakhle, outlines the key challenges and solutions for decarbonizing the aviation sector, including energy efficiency improvements, alternative fuels, traffic reduction, and regulatory interventions.
