The global freighter fleet is expected to expand by 70% in the next 20 years, raising concerns about the environmental impact of increased freight capacity. Organizations like ICAO and IATA are promoting sustainability efforts, including a roadmap for achieving net-zero emissions by 2050. Innovations such as Sustainable Aviation Fuel (SAF) are being explored, with SAF potentially reducing lifecycle emissions by up to 80%. However, challenges like high production costs and limited feedstock availability persist. Airports are also adopting renewable energy and waste management strategies to further enhance sustainability in aviation.
