QRITOS: targeting contrails and smarter SAF deployment

Imperial College London joined a Rolls-Royce–led initiative to optimize SAF deployment as a tool for reducing non-CO2 climate impacts from flying. The QRITOS project, announced publicly on November 7, 2025, brings together Rolls-Royce, British Airways, Heathrow, and Imperial College London, with funding support from the Aerospace Technology Institute’s Non-CO2 Programme. The project’s core aim is to demonstrate that targeted SAF use—guided by computational contrail models and satellite observations—can deliver measurable reductions in contrail-induced warming, while leveraging existing fuel supply to maximize environmental benefits. The program is designed as a two-year effort, wrapping up in April 2027, with milestones that include enhanced forecasting methods, better contrail modeling, and verification using satellite data. Industry leaders and government partners framed QRITOS as a practical route to smarter SAF deployment, one that could help the UK maintain leadership in sustainable aviation as SAF supply grows. Sebastian Eastham, Imperial’s Associate Professor in Sustainable Aviation, stressed that the project’s value lies in learning how to detect, track, and analyze contrails to inform more effective SAF use. The program’s framing around non-CO2 effects reflects a broader shift in how aviation climate impact is understood and addressed. (imperial.ac.uk)

This collaboration sits within a broader policy and industry context. The QRITOS briefing is connected to the government’s Non-CO2 Programme and the ATI Roadmap, which emphasize reducing non-CO2 emissions alongside traditional CO2 reductions. The policy backdrop notes that SAF use in the UK is expected to increase as mandates expand, with targets to reach 10% SAF in UK fuel by 2030 and 22% by 2040 as part of longer-term climate commitments. The QRITOS project’s approach—combining modeling, satellite data, and industry flight trials—illustrates how the UK intends to translate SAF potential into measurable climate benefits across real-world aviation operations.
