Singapore has taken a major step toward sustainable aviation. It is now the first country to introduce a nationwide green flight tax. The Civil Aviation Authority of Singapore (CAAS) announced that the new levy will apply to passengers departing from the country starting October 1, 2026. Any ticket issued from April 1, 2026, will include the charge. The plan forms part of a wider green aviation policy in Singapore that aims to cut emissions and promote cleaner flying.
The move also brings environmental costs directly into airfare through a transparent eco travel tax. It marks a noticeable shift in how governments may choose to support greener aviation in the future.
How the Tax Works
The levy is a sustainable aviation surcharge. It changes based on the distance of the trip and the travel class. Passengers in economy and premium economy will pay S$1 on short regional routes and up to S$10.40 on long-haul flights. These include routes to Europe and the United States.
Meanwhile, business and first-class travellers will pay more. Their surcharge ranges from S$4 to S$41.60, depending on the distance. Authorities structured the charges this way because premium cabins consume more space and result in higher emissions per passenger.
Cargo flights, private jets, and charter services are also included in the policy. In those cases, the levy depends on aircraft weight or payload. However, transit passengers will not pay the tax. Humanitarian and pilot training flights are also exempt.
Airlines must show the charge as a separate line on every ticket. This makes any Singapore airfare increase clear to passengers and improves transparency.

Sustainable aviation fuel (SAF) is one of the most effective ways to lower carbon emissions from flying. However, SAF is more expensive than traditional jet fuel. Instead of shifting all costs onto airlines, Singapore is spreading responsibility across the industry and its passengers. This new system supports the country’s broader eco-friendly travel regulations.
Funds collected through the levy will go to SAFCo, a new state-backed company. SAFCo will buy sustainable aviation fuel in bulk and distribute it to airlines flying out of Singapore. This centralized approach helps stabilise prices and encourages consistent adoption. It also gives Singapore stronger purchasing power than if airlines bought fuel individually.
The initiative supports Singapore’s goal of using at least 1% SAF by 2026, rising to 3–5% by 2030. Progress will depend on global supply and production capacity.
Will Travellers Notice the Change?
Most passengers will notice only a small addition to their ticket price. A few extra dollars on a long-haul economy fare is unlikely to change travel plans. Still, the policy represents a shift in thinking. Passengers will begin contributing directly to the environmental cost of flying.
With this surcharge, Singapore has become the first major air hub to build SAF funding directly into ticket prices. If the approach succeeds, other countries may choose to follow. The move could speed up global adoption of low-carbon fuel and reshape how the aviation industry funds its climate goals.
In short, the immediate price change may be small. However, the impact on the future of flying could be significant. Singapore is setting a new expectation: flying responsibly may soon become part of the cost of every journey.
