Section 1.1
Economic, Social, and Technological Impact

Aviation is a vital global economic driver, providing millions of jobs and facilitating international trade and travel. Technological advancements have improved efficiency and lowered costs, making air travel more accessible. However, balancing the industry’s economic impact with the pressures to reduce its emissions remains a significant challenge.

Economic Impact

Aviation stands as a global economic powerhouse. It directly employing over 87.7 million people worldwide[3]. Besides providing employment it also encourages the growth of job opportunities, in industries, like tourism, logistics and manufacturing.

An increase in connectivity equivalent to 10% of a nation’s GDP has been associated with a 0.9% improvement in total factor productivity [4]. Its contribution to the global GDP is remarkable, accounting for 4.1% or $3.5 trillion, comparable to the economies of Japan and Germany [5] [6]. Additionally, about 35% of global trade by value, amounting to $6.8 trillion, depends on aviation annually [7].

Social Impact

The sector has revolutionized global travel and social interactions, with traveler numbers soaring from 52 million in 1950 to 7.8 billion in 2019 [8]. This growth not only symbolizes aviation’s role in enabling cross-cultural exchanges but also its influence on everyday life. Linked closely with tourism, aviation is a key revenue source for many countries. Its critical role was evident in 2019, with 4.3 billion passengers contributing to the Travel & Tourism sector’s 7.6% share of global GDP in 2022 [9] [10].

Efficiency and Technological Advancements

Significant improvements in aircraft design, engines, and navigation have enhanced efficiency. Modern planes are approximately 45% more fuel-efficient than those in 1968, leading to a 70% reduction in ticket prices since the 1970s and fueling an aviation boom [11] [12]. These advancements have not only shortened travel times and improved passenger comfort but have also expanded the range of flights. For instance, the range of aircraft has more than doubled since the 1970s, with the Airbus A350-900ULR’s 11,000-mile capability in 2018 far surpassing the Boeing 747’s 5000-mile range [13]. The speed and flexibility of air transport are particularly advantageous for businesses, significantly impacting their growth.

Balancing Emission Concerns

With ongoing concerns about aviation’s carbon footprint, balancing decarbonization efforts with the sector’s substantial economic impact remains a significant challenge for our times.
