Details

The government is introducing the Sustainable Aviation Fuel Bill 2025 to provide legislative powers for the SAF revenue certainty mechanism.

The revenue certainty mechanism seeks to lower financing costs and increase the chances of first-of-kind SAF projects reaching successful final investment decisions. This will help attract investment into UK SAF projects and increase domestic SAF production, which will:

• promote growth in the aviation industry
• contribute towards meeting the SAF Mandate 

Our cost-benefit analysis and dataset sets out the quantitative analysis and modelling that underpins our decisions for provisions within the bill. The analysis uses a range of assumptions to illustrate the potential economic outcomes associated with the revenue certainty mechanism.

Scenarios indicate various possible outcomes, risks and benefits associated with SAF.
