Question to the Department for Transport:

To ask the Secretary of State for Transport, whether he has made an estimate of the potential impact of the introduction of sustainable aviation fuel on the cost of flights in the next five years.

The Government has committed to introduce a mandate to supply sustainable aviation fuel (SAF) from 2025 to help decarbonise the aviation sector in line with our Jet Zero Strategy. The Government recently launched a consultation on the future levels of the SAF mandate targets including analysis of the costs and benefits of a range of trajectories.

The uncertainty around future SAF costs makes it difficult to predict exactly how much ticket prices could increase by. However, any impact is expected to be relatively small.

Passing SAF costs onto passengers is ultimately a commercial decision for airlines.
