Singapore plans to require all flights departing the country to use sustainable aviation fuel (SAF) from 2026, its transport minister said on Monday, as the city-state joins the global aviation industry's efforts to switch to greener fuel.

Under the plan, announced by Chee Hong Tat at the Changi Aviation Summit on the eve of the Singapore Airshow, the country aims for a 1% SAF target from 2026 and plans to raise it to 3-5% by 2030, subject to global developments and the wider availability and adoption of SAF.
