Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment he has made of the role that hydrogen vehicles can play in tackling air pollution.
In 2018, the Department for Transport published the outputs of the Transport Energy Model. The model provides a clear assessment of the relative environmental impacts of a range of fuel and powertrain options for cars, vans, buses and heavy goods vehicles over the period to 2050, including hydrogen fuel cell vehicles.
