Propelling the Future of Aviation
Our Mission
Willis Sustainable Fuels brings together leading aviation, project development, and technical expertise partners to deliver sustainable SAF solutions to decarbonize aviation and help our customers connect the world through sustainable flight.
Why SAF?
Our dedication stems from a deep understanding of the critical role the aviation industry plays in connecting the world and the urgent need to address its environmental impact.
Here is why producing SAF is not just a choice, but a responsibility:

Reducing Greenhouse Gas Emissions
SAF can reduce lifecycle greenhouse gas emissions compared to conventional jet fuels. By integrating SAF into the aviation fuel mix, the industry can significantly reduce greenhouse gas emissions.
Seamless Integration
SAF is designed to be a ‘drop-in’ solution, which means it can be blended with conventional jet fuel without any modifications to existing engines or infrastructure.
Fostering Economic Growth
Investment boosts job creation and growth in both aviation and renewable energy sectors.

What We Do
Willis Sustainable Fuels is committed to delivering scalable solutions to decarbonize the aviation industry by investing in, developing, and producing Sustainable Aviation Fuel (SAF).
First SAF Facility
Our first SAF facility will take shape in Teesside, United Kingdom. Teesside, renowned for its industrial heritage and progressive vision is the ideal foundation for our groundbreaking SAF endeavor.
Deliverables
- Partnership with Johnson Matthey and Axens on technology.
- McDermott as engineering, procurement, and construction (EPC) partner.
- Targeting operational launch in 2028.
High-quality Advanced SAF
The SAF is made from biomethane with a least 80% greenhouse gas emissions reduction compared to today's fuels.

Willis Sustainable Fuels (UK) Limited was awarded £4.721 million by the UK Government's Department for Transport through the Advanced Fuels Fund.
Evolution
Our first facility will be designed to deliver second generation bio-SAF today and lead the pathway to a power-to-liquids future.
Global Vision
We are actively exploring strategic locations globally for the establishment of additional SAF facilities. This strategic expansion is aimed at scaling our operations to meet the growing worldwide demand for sustainable aviation solutions while fostering local partnerships and propelling a collective effort towards a more sustainable future for aviation on a global scale.
Carbonshift Process
Willis Sustainable Fuels is licensing Carbonshift’s FlexFeed technology which flexibly uses biomethane or green hydrogen + atmospherically sourced carbon dioxide (CO2) to produce next generation SAF, either bio-SAF or Power-to-Liquid (PtL), depending on the configuration.
With this flexibility we respond to market demand and can deploy ‘PtL-ready’ projects now.
