915 million tonnes
Worldwide, flights produced 915 million tonnes of CO2 in 2019. Globally, humans produced over 43 billion tonnes of CO2.
In 2019, 4.5 billion passengers were carried by the world's airlines.
Nearly 88 million jobs were supported worldwide in aviation and related tourism before Covid-19 hit the industry. Of this, 11.3 million people worked directly in the aviation industry.
17th in the world
If aviation were a country, it would rank 17th in the world in terms of gross domestic product (GDP), generating $691.3 billion of GDP per year, considerably larger than some members of the G20 (and around the same size as the Netherlands).
By 2038, it is forecast that aviation will directly contribute $1.7 trillion to world GDP.
The Airbus A380 and A220, Boeing 787, ATR-600 and Embraer E2 aircraft use less than 3 litres of jet fuel per 100 passenger kilometres. This matches the efficiency of most modern compact cars.
Aviation is responsible for 12% of global CO2 emissions from all transport sources, compared to 74% from road transport.
Commercial aviation is responsible for about 2-3% of global carbon emissions.
