The mode of transport chosen by Royal Mail is an operational decision, over which Ministers and the regulator have no role under postal regulation. It has emphasised the low-carbon credentials of its road fleet, using electric vans and biofuel in HGVs to reduce emissions. However, I have already encouraged Royal Mail, and will continue to encourage it, to take an ambitious approach to the wider use of rail freight as part of its commitments to net zero and to reducing congestion our roads, including exploring the innovative and growing express rail freight sector. I assure your Lordships’ House that, in my new role as rail Minister, I will be championing the role of freight on our railways.
