Singapore’s first green jet fuel group-buy trial at the Changi Aviation Summit is an example of national-wide demand aggregation to create a market signal and a sign that stakeholders are thinking about sustainable aviation fuel (SAF) beyond just volume commitments. By creating a collective purchasing mechanism, Singapore is helping buyers coalesce around SAF demand while supply continues to grow, thus strengthening the long-term investment case for producers.   What stands out is how this is...

Every airline today faces the same reality: sustainable aviation fuel (SAF) is more expensive than conventional jet fuel. It’s in limited supply and yet the pressure to adopt it keeps climbing. To simplify procurement and meet compliance, most carriers contract a uniform SAF blend upstream. However, uniformity isn’t always efficient due to varying regional contexts, whereby different markets face distinct regulatory environments, infrastructure readiness, and operational constraints. A rigid,...

Sustainable aviation fuel (SAF) is widely recognised as a critical lever for reducing aviation’s carbon footprint. Yet, one challenge continues to dominate conversations across the industry: cost. In 2023, the World Economic Forum reported that SAF costs three to five times more than conventional Jet A1 fuel [1]. Two years later, the International Air Transport Association (IATA) approximated SAF to be 4.2 times more expensive than conventional fuel, driven partly by...
