Understanding the levy
The Civil Aviation Authority of Singapore Amendment Act 2025 introduces a transparent levy on every passenger ticket cargo consignment and charter flight departing from Changi Airport. The levy will be collected by airlines at point of sale then transferred to the authority. Because it is flat rather than percentage based it does not penalise premium travel more than economy seats, a subtle design choice that encourages airlines to keep upgrading cabin density without worrying about higher charges. That choice quietly aligns environmental goals with revenue management strategies.
Inside the SAF Fund
Collected sums flow into the new Sustainable Aviation Fuel Fund. Money can only be withdrawn for certified SAF purchases related environmental attributes and research supporting alternative propulsion. Ring fencing the cash in this manner builds clear demand signals for fuel producers and helps unlock scale production agreements in the region. A less discussed feature is that unused balances will generate interest credited back to the Fund, giving a compounding effect that could cover future price differentials once SAF prices converge with conventional jet fuel.
Strategic implications for finance and leasing
Airlines gain a new compliance cost yet also a clearer pathway toward meeting corporate emissions targets demanded by lenders. Banks can reference the levy schedule when structuring green linked loans, turning a statutory obligation into a measurable key performance indicator. Lessors with modern fuel efficient fleets become even more attractive, as lessee airlines can stack aircraft efficiency gains with guaranteed SAF allocations to improve reported carbon intensity.
Practical mitigation moves
- Negotiate multi-year SAF offtake contracts early
- Bundle levy payments into passenger surcharge disclosures for transparency
- Use fund participation data when issuing sustainability reports
Conclusion
Singapore has moved swiftly from policy concept to enforceable mechanism, combining predictable funding with demand aggregation. The model provides investors with rare regulatory certainty and could become a blueprint for other hub airports seeking balanced aviation growth.
