My Lords, the noble Baroness is right to point out the progress that we have made on buses. The Government have supported the use of a range of low-carbon bus technologies, including the deployment of 62 hydrogen buses and supporting infrastructure. Our £23 million hydrogen for transport programme is increasing the uptake of other fuel cell electric vehicles and growing the number of publicly accessible hydrogen refuelling stations. We have also been supporting public and private sector fleets to become early adopters, through the £2 million fuel cell electric vehicle fleet support scheme. This initiative is very important to the Government in trying to provide a number of different strategies and support mechanisms, not just financial ones.
