What assessment she has made of the potential implications for her policies of current levels of global (a) production capacity of Sustainable Aviation Fuel and (b) demand for Sustainable Aviation Fuel.

Reply

Significant analysis was undertaken during the development of the Sustainable Aviation Fuel (SAF) Mandate. Government considered global production capacity and the UK’s ability to access SAF for a range of SAF conversion processes, including hydroprocessed esters and fatty acids (HEFA). To ensure the SAF Mandate reflects the latest technological and commercial developments, there is continuous monitoring of trends and impacts of the Mandate. HEFA will play an important role in the global SAF sector, particularly in the early years of the Mandate. However, the HEFA cap is to encourage the development of new technology pathways so that meeting the SAF Mandate is not reliant on HEFA feedstocks, which are likely to become scarcer. We have carefully balanced setting the HEFA cap in a way that recognises the fact HEFA is the only currently commercially available type of SAF to mitigate against unintended consequences. The corresponding EU SAF Mandate does not place a cap on HEFA, however, the EU’s overarching Renewable Energy Directive does place a limit on certain feedstocks that can be used across transport uses. Officials regularly engage with European counterparts and stakeholders to understand policy developments in the EU and share learnings from SAF policy.

What assessment she has made of the potential impact of the decision to pause the next phase of electrification of the Midland Main Line on rail (a) times and (b) investment in the East Midlands.

Reply

The Spending Review prioritised investment across all government spending, taking account of business cases and affordability. While I appreciate the investment opportunities that further electrification of the Midland Main Line could bring to the East Midlands, schemes that would have a more significant impact on economic growth were prioritised for funding. There is still significant investment being made in rail and we will continue to keep this project under review as part of our longer-term pipeline of schemes. Ahead of further funding becoming available to complete electrification of the route, EMR’s new intercity bi-mode trains will provide a step change in journey quality for rail passengers travelling between South Yorkshire, the East Midlands and London. The new trains will be quieter, more comfortable and will reduce carbon emissions by running using electric overhead lines between London and Wigston, south of Leicester. When fully operational they will provide a 46 per cent increase in capacity through a mixture of a greater number of seats and units.
