Over 30 countries have implemented or announced SAF mandates, targets, or incentives, with several others actively exploring a shift from voluntary adoption to compliance-driven frameworks.

EU: ReFuelEU mandates 2% SAF by 2025, rising to 6% in 2030, and 70% by 2050, with sub-targets for synthetic fuels of 1.2% of total SAF by 2030, 35% by 2050.

UK: SAF mandate requires 2% in 2025, rising to 10% SAF by 2030, increasing to 22% by 2040, including a synthetic fuel (PtL) sub-target of 0.2% of total SAF in 2028, rising to 0.5% by 2030 and 3.5% by 2040. Has a HEFA cap set at 71% of total SAF by 2030, decreasing to 35% by 2040.

Singapore: SAF requirement starts at 1% in 2026, scaling to 3-5% by 2030, funded via a passenger levy.

U.S.: The SAF Grand Challenge targets 3 billion gallons/year (11.4 billion liters) by 2030, supported by tax credits under the Inflation Reduction Act.

ICAO / CORSIA: SAF is recognized under CORSIA as a core emissions reduction pathway for international aviation.

There are 11 ASTM-approved conversion pathways for SAF production under the D7566 standard, and 11 other processes are currently under evaluation.

Currently, HEFA is the only pathway with a Technology Readiness Level (TRL) of 9, indicating full commercial deployment. Most operational facilities still rely on HEFA, which makes up >90% of global SAF production due to lower capex and proven performance.

HEFA can achieve around 60-80% GHG emissions savings compared to fossil jet fuel.

Corporate buyers like Microsoft are increasingly committing to SAF as part of Scope 3 emissions reduction strategies, especially for business travel and air freight.

This demand is voluntary but growing rapidly, often facilitated through Book & Claim systems that allow emissions reductions to be decoupled and credited to buyers without requiring physical delivery of SAF.
