Airlines connect people and economies worldwide, but outcomes depend on more than routes: emissions, reliability, and workforce roles shape what passengers and communities experience. This page traces where aviation greenhouse-gas emissions come from, how sustainable fuel and newer, fuel‑efficient aircraft are changing the mix, and how traveler preferences are shifting. It also explores the pressures behind delays and safety performance, and where investment—from airports to digital payments and merchandising—is headed next.
Key Takeaways
- 42% of the world’s CO2 emissions come from transport across the globe (including aviation), per IPCC AR6 transport sector assessment
- $240 billion expected value of sustainable aviation fuel (SAF) investment globally by 2050 (scenario analysis) reported by industry research from BloombergNEF
- 31.3% of global aviation GHG emissions are from international aviation in 2019 (best estimate) per IPCC AR6 aviation chapter
- 8.5% of flights are delayed by more than 15 minutes on average in 2023 in the global benchmark used by Cirium’s on-time performance report
- 8.5% of flights delayed by more than 15 minutes on average in 2023 (global on-time performance benchmark used by Cirium).
- 7.2% year-over-year reduction in jet fuel prices (regional average) in 2023-to-2024 transition, as reported in EIA aviation fuel market updates
- 20.6% of airlines’ workforce is in ground handling roles in the US (share of aviation ground support employment), based on BLS Occupational Employment Statistics aggregation for NAICS 481
- $0.70 per liter average jet fuel price level in 2023 (global jet fuel price average reported by a reputable market data provider in annual review).
- 1,000+ airports in the US participate in FAA’s Airport Improvement Program (AIP) eligible airport list for capital grants; FAA publishes this participation through grant program guidance
- 2,700+ aircraft grounded during peak COVID period in 2020 (global airline fleet grounding), per FlightGlobal analysis using Cirium/Flightradar-type fleet data
- 7.4% of airlines’ fleet delivered in 2023 were next-generation fuel-efficient aircraft (A320neo/B737 MAX/A220 and similar) as per Cirium Fleet data summary
- 10.2% of global airline passengers used mobile boarding passes in a 2023 airline app usage study by Amadeus
- 24.0% of surveyed airlines planned to increase spending on airline digital merchandising and retailing in 2024, according to Amadeus travel payments research
- USD 78.2 billion total global airline passenger revenue expected in 2023 for US airlines (domestic + international passenger services), based on BTS economic statistics (Table 1.1)
- 0.08 aviation hull-loss accident rate per million flights in 2022 (Boeing Statistical Summary of Commercial Aviation Accidents).
Aviation faces pressure to cut emissions while investing in SAF and digital upgrades amid costly delays.

Interpretation
Sustainability Interpretation
Sustainability in aviation is moving, but the impact gap remains large because international aviation accounts for 31.3% of global aviation GHG emissions while only about 2.1% average annual reductions in emissions intensity come from modernization, even as investment in sustainable aviation fuel is projected to reach $240 billion by 2050.
