Environmental compliance is no longer a PR move; it’s a line item on your balance sheet.
Starting in 2026, the Singapore SAF Levy has officially changed how we calculate the Net Book Value (NBV) of aircraft. With flights departing Singapore now subject to mandatory Sustainable Aviation Fuel (SAF) contributions, fuel efficiency has moved from a “preference” to a “financial mandate.”
We are seeing the emergence of “Brown Discounts.” Older, less fuel-efficient aircraft that cannot technically support high SAF blends or that suffer from higher fuel burn are being devalued more aggressively. Conversely, “SAF-ready” modern airframes are seeing their residual value curves flatten out, becoming more attractive to ESG-conscious institutional investors.
Valuation Tip:
When assessing widebodies for long-haul routes (Bands III and IV), the impact of these levies can represent a significant percentage of operating costs. Engineering efficiency is now the primary driver of asset liquidity.
