I am pleased to say that rail is already the greenest form of transport, but more is indeed needed to meet our contribution to achieving net zero by 2050. For instance, 9% of all passenger miles are covered by electric vehicles, so it accounts for only 1% of transport emissions across the sector. We are investing in electrification, particularly on the trans-Pennine route upgrade—to electrify and upgrade the main arterial route between Manchester, Huddersfield, Leeds and York. I cannot give my noble friend any commitments today, obviously, on extending the great western main line electrification, but we are working to identify other opportunities for further electrification in light of the spending view.
