The aviation industry is a critical component of the global economy, facilitating international trade, tourism, and connectivity. It encompasses a wide range of activities, including passenger and cargo transportation, aircraft manufacturing, and airport operations.
According to the December 2024 ATAG factsheet, the sector supports roughly 86.5 million jobs and contributes about US$4.1 trillion to global GDP.
2025 global passenger traffic is projected to reach 9.8 billion passengers, reflecting a 3.7% Year-on-Year growth from 2024 (ACI World 2025)
Regional Insights
Australia
Australia’s aviation sector is vital for connecting the vast country and supporting its economy. Australia’s aviation sector plays a critical role in supporting national productivity, connectivity, and economic resilience.
According to the Australian Airports Association’s most recent economic contribution report, prepared by Deloitte Access Economics (2023), Australia’s airports contributed AUD $105 billion in value added to the national economy in 2022 and supported more than 690,000 full-time equivalent jobs. This represents approximately 5% of Australia’s GDP and around 6% of total national employment. (Source: Australian Airports Association, 2023).
Major airports like Sydney, Melbourne, and Brisbane serve as key hubs for both domestic and international travel. The sector is also crucial for tourism, according to Tourism Research Australia, international visitation to Australia reached 7.8 million trips in the financial year ending June 2025.
Southeast Asia
Southeast Asia is widely recognised as one of the fastest-growing aviation markets globally. The region’s strategic geographic position, expanding middle class, and rising demand for affordable air travel have all contributed to sustained growth in passenger traffic.
ASEAN countries feature an extensive air-transport network, anchored by major hubs such as Singapore Changi, Kuala Lumpur International and Suvarnabhumi Airports, and serve hundreds of millions of passenger movements annually.
In the ASEAN region, the air transport sector supports an estimated 17 million jobs and contributes around USD 210 billion to regional GDP (IATA/ASEAN data).
Europe
Europe’s aviation industry is highly developed, with a dense network of airports and airlines connecting the continent and beyond. The sector supports 13.5 million jobs and contributes €886 billion to the European economy (Airports Council International Europe, 2024).
Major airports such as London Heathrow, Paris Charles de Gaulle and Frankfurt rank among Europe’s busiest aviation hubs. The global tourism sector is also rebounding strongly, with international arrivals continuing to reach hundreds of millions annually (UNWTO)
Industry Specific Challenges:
The aviation industry faces several challenges, including environmental sustainability, regulatory compliance, and operational efficiency.
Aviation Emissions & Climate Impact
According to the International Energy Agency (IEA), aviation accounted for 2.5% of global energy-related CO₂ emissions in 2023, having grown faster between 2000 and 2019 than rail, road or shipping. Efforts to reduce the industry's carbon footprint include the development of sustainable aviation fuels, improvements in aircraft technology, and the optmisation of operations.
Navigating Complex Regulatory Requirements
Regulatory compliance is another critical challenge, with airlines and airports needing to adhere to a complex web of international, regional, and national regulations. This includes safety standards, environmental regulations, and passenger rights.
Operational Efficiency in a Competitive Market
Operational efficiency is essential for maintaining profitability in a highly competitive industry. This involves optimising flight schedules, reducing turnaround times, and improving baggage handling processes.
Digital Transformation Driving Industry Performance
The adoption of digital technologies, such as artificial intelligence and the Internet of Things, is playing an increasingly important role in enhancing operational efficiency and improving the passenger experience.

Are there any sustainability related certifications specific to Airports?
The Airport Carbon Accreditation Program (ACA) is a globally recognised carbon management certification program for airports offering seven levels of certification. The Global Real Estate Sustainability Benchmark (GRESB) infrastructure assessment also includes sector specific analysis to enable your organisation to compare its ESG performance with other operators in your space.
Do Civil Aviation Authorities provide guidance on emissions management?
Yes. Most national Civil Aviation Authorities offer guidance or regulatory requirements related to greenhouse gas emissions, fuel efficiency, environmental reporting, and climate initiatives. While their primary mandate is aviation safety, many CAAs support or regulate emissions management through policies, standards, and compliance frameworks aligned with ICAO (International Civil Aviation Organisation).
