Net Zero, Energy and Transport Committee

Transport Policies and Performance

Meeting date: 7 October 2025

Bob Doris

I thought that I would ask about the Scottish Government’s current position on car usage. I am conscious that, in 2020, there was an ambition to reduce the number of car kilometres travelled by 20 per cent, and this year there has been a renewed policy statement in partnership with COSLA that is still about tackling car usage but it has no specific target. That might be a reflection of the Climate Change Committee advice that we got this year that modelled a required reduction in car usage for carbon budgets of 6 per cent by 2035, which is very different from the 2020 target. It would be helpful for the committee to understand what the Scottish Government’s ambition is for the reduction in car usage.

Meeting date: 7 October 2025

Bob Doris

Although we will get more information on a sectoral basis across the portfolio when the climate change plan is published, I am conscious that the 6 per cent reduction predicated by the UK Climate Change Committee—if I have got this right—means a 6 per cent reduction in anticipated growth in car usage rather than a reduction in kilometres. At this stage, can you say whether the Scottish Government’s position is that it wishes to see fewer kilometres travelled by car or to constrain the growth in kilometres travelled by car? I am conscious that you also mentioned that it is about reducing emissions as much as it is about reducing kilometres.

Okay, so we will have to wait and see the climate change plan to know whether the Scottish Government’s position is for fewer kilometres.

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

Graham, can I come in here? I read the briefing papers in the past few days, and this is all new to me. I get what you are saying about the major adaptations that would have to be made to storage and so on. Could liquid hydrogen be used for short haul, say Aberdeen to Dublin or Glasgow to London? Could there be fleets that service that market? Is that worth pursuing?

That is helpful, because my next question was going to be about battery electric for planes. Hold on to that thought, because I want to know whether the other witnesses have any views on liquid hydrogen. All that I can go on is the notes that I made in preparation for the meeting, which say that, by 2027, we are looking at 80-seater planes using liquid hydrogen for short haul. The question is whether, if technological advances go further, that is worth pursuing. I have no view on it. The committee wants to ensure that every aspect of technological advancement to pursue net zero for aviation is being explored. Liquid hydrogen is one of those technologies, so I want to tease that out. Are there any other views on liquid hydrogen? If not, perhaps you could comment on the use of battery electric for planes. Sebastian? Hold that thought, because Mark Morrison is taking up the cudgels.

Bob Doris

Before I move on to Mark Morrison, do you want to say anything about battery electric aircraft, Dr Eastham? I think that it said in our papers that Norway is hoping to move by 2030 to all short-haul and some medium-haul flights being battery electric, with the new fleets for those flights being almost exclusively battery electric.

Thank you.

It is almost as though you knew that I was going to mention hydrogen and did a link for me, convener.

I know that we have spoken about hydrogen, and Graham Hutchings in particular talked about some drawbacks of using liquid hydrogen in flights. We spoke a bit more about using it as a power source to produce SAF, but there are opportunities for using liquid hydrogen directly as an aviation fuel, not as SAF, because it is not a drop-in fuel. Does it have the potential to lower emissions and be part of the mix in making aviation carbon neutral? Given that I have taken Graham Hutchings’s name in vain, perhaps we should go to him first.

That is helpful.

Mercedes, I will bring you in, but because of time constraints, I will ask you an additional question. You can answer this final one or you can reflect on the two that I have already asked—that is up to you.

I have a wee note that says that there have been really good improvements in fuel efficiency over a number of years. Have we squeezed that as far as we can, or can we make more improvements?

That particular question does not have to be for you, Mercedes. I have asked three questions now; do you have reflections on any of them? If any of the other witnesses want to come back in on any of those, I would also be delighted to hear from them.

That is very helpful. Do any other witnesses have final reflections on the questions that I have asked?
