WSF and GFI launch accelerator to unlock UK SAF projects

December 9, 2025 |

In Canada, AviTrade reported that Willis Sustainable Fuels UK (WSF), a subsidiary of Willis Lease Finance Corporation (WLFC), and the Green Finance Institute (GFI), an independent adviser to governments and investors, have launched a sustainable aviation fuel project accelerator.

The initiative is designed to progress WSF’s SAF project at Wilton International in Teesside to ‘Final Investment Decision’ and to create a repeatable model for financing new domestically produced transition projects.

Since the start of 2025, the UK’s SAF mandate has required increasing levels of SAF in the national jet fuel supply, reaching 10% in 2030 and 22% in 2040, according to the report.

WSF’s Teesside project is one of the UK’s most advanced second-generation SAF developments, using existing, proven technology to produce SAF from waste. Targeting 14,000 tons of production per year, the project is expected to support national energy security by reducing reliance on imported fuels and to create new green-industry jobs in the Northeast, converting mainly UK biomethane into next-generation jet fuel, it added.
