Mr. Kenneth Spratt:

There is a lot to be done when it comes to the decarbonisation of HGVs. They will be much more difficult for us to make progress on by comparison with the private car. We have some technologies that are useable by HGVs. The technologies are not as well developed for such vehicles as they are for the private car. Insofar as the main fuel that is used at the moment for HGVs is diesel, that will continue to be the case for a number of years but, again, the OLEV needs to come up more options for them.
