The air transport industry supported a total of 86.5 million jobs globally in 2023, including direct, indirect, induced and aviation-enabled tourism jobs.
In 2023, 4.4 billion passengers were carried by the world's airlines (1.8 billion international passengers and 2.6 billion domestic passengers). The estimate for 2024 is 5 billion passengers.
If aviation (direct impact) were a country, it would rank 20th in the world in terms of gross domestic product (GDP). This amounts to $1.1 trillion, which is similar to the GDP of Saudi Arabia and equivalent to 1% of world GDP for 2023.
While air transport carries less than 1% of the volume of world trade shipments, it represents around 33% by value – meaning that goods shipped by air are very high value commodities and often perishable or time-sensitive.
The overall contribution to global GDP that is supported by aviation is 3.9%.
The global aviation industry has a goal of net zero carbon emissions by 2050, supported by accelerated efficiency measures, energy transition and innovation across the aviation sector in partnership with governments around the world.
Jet aircraft in service today are over 80% more fuel efficient per seat kilometre than the first jets in the 1950s.
The latest generation of aircraft have up to a 75% reduction in the noise footprint, compared to the first jets.
Around 80% of aviation CO2 emissions are emitted from flights of over 1,500 kilometres, for which there is no practical alternative mode of transport.
The average aircraft occupancy in 2023 was 82.2%, which is far higher than for other modes of transport.
The global aviation industry produces around 2.05% of all human-induced CO2 emissions.
348.75 billion litres of jet fuel were used by commercial operators in 2023. This represents 7-8% of global liquid fuel use.
Global policy developments are making SAF a more important strategic consideration for aircraft operators which has resulted in major forward purchase agreements. As of early 2023, around $45 billion in SAF purchase agreements had been made by airlines (compared to $6 billion pre-Covid).
Aviation fuel should be 5% less carbon intensive by 2030, compared to today’s fossil fuels, as part of a gradual shift towards SAF and lower carbon aviation fuels.
Alternative fuels, particularly sustainable aviation fuels (SAF), have been identified as excellent candidates for helping achieve aviation's climate targets. SAF-derived sources such as algae, jatropha or waste by-products have been shown to reduce the carbon footprint of aviation fuel by up to 80% over their full lifecycle.
Today, SAF is blended with conventional kerosene in ratios of up to 50% to ensure compatibility with aircraft, engines and fuelling systems.
The major airframe and engine manufacturers are working to ensure that all aircraft can safely operate on 100% SAF by around 2030.
