In its 2025 sustainability report, Aviation Capital Group (ACG), a global full-service aircraft asset manager, said it had lowered emissions in its fleet while adding new aircraft.
Among the highlights of the report were that the Newport Beach-based group had increased the share of new-generation, lower-emissions aircraft in its fleet to 79% as part of its modernisation programme. The weighted average age of the fleet dropped to 5.4 years last year from 6.2 years in 2024.
The lessor added 52 new-generation aircraft during the year while exiting 36 older models, helping to reduce its relative emissions to 13% below a 2018 baseline. ACG said its portfolio emissions are now 14% lower than the industry average, reflecting the growing weighting of more fuel-efficient aircraft.
The company also expanded its forward orderbook, with future commitments rising to more than 180 aircraft as of February 2026, underlining its focus on long-term fleet renewal.
Alongside fleet changes, ACG advanced its sustainable finance strategy. It extended and upsized its sustainability-linked loan to $575m and signed its first sustainability-linked leases, linking financing terms more closely to environmental performance.
Beyond its core operations, the group said it supported more than 20 charitable and community initiatives worldwide during the year.
ACG’s latest update highlights the increasing role of fleet modernisation and financing structures in driving sustainability progress across the aircraft leasing sector.
“While the path to achieving net zero by 2050 is becoming increasingly demanding, we remain committed to shaping a sustainable future by deepening our impact as a business and broadening our influence,” said Thomas Baker, Chief Executive Officer and President of ACG.
ACG is a full-service aircraft asset manager with approximately 450 owned, managed and committed aircraft as of December 31, 2025, leased to roughly 85 airlines in approximately 50 countries. In 2024 it had 496 aircraft under management. In 2025, 94% of its aircraft were narrow bodied. That year the firm had total assets of $14bn with a Baa2 credit rating from Moody’s and BBB- from S&P Global.
