Decarbonising Aviation

Debate between Kerry McCarthy and Gary Streeter

Tuesday 21st September 2021 Westminster Hall

[Kerry McCarthy (Bristol East) (Lab)]

Thank you, Sir Gary, it is a pleasure to see you in the Chair. I congratulate my hon. Friend the Member for Putney (Fleur Anderson) on securing what is a very important and timely debate, given that only a few weeks remain until the UK hosts COP26, where transport emissions will, of course, be a key item on the agenda. We have heard some excellent and informative speeches, including those by my hon. Friend the Member for Putney, my right hon. Friend the Member for Hayes and Harlington (John McDonnell) and the hon. Member for Richmond Park (Sarah Olney), who spoke out against the expansion of Heathrow. Other Members talked in more detail about proposals to decarbonise aviation and some of the obstacles in the way.

Given that it remains the largest contributor to UK emissions, decarbonising our transport sector must be a priority for the Government. Aviation is a key part of that and accounted for 7.3% of UK emissions in 2018. Sadly, we have seen the progress on decarbonisation of transport flatlining over recent years. Progress has been made in some areas, such as in decarbonising the energy sector, but it is disappointing that so little has been done and so little progress has been made on transport.

Aviation is one of the most difficult sectors to decarbonise, but as we have heard from hon. Members, particularly the hon. Member for Angus (Dave Doogan), there are solutions. There are sustainable aviation fuels derived from waste; there are electric or hydrogen-powered planes for at least short-haul journeys in the foreseeable future; and there is airspace modernisation.

Ministers in Westminster Hall debates probably hate it when speeches finish early, so there is more time for them to answer. Normally, they can say, “Well, if only I had time to answer all these questions—”. I will ensure that the Minister has lots of time to answer what are quite a few questions from me and other Members.

Where are we on some of the things that are out there? For example, the EU is proposing to mandate the use of blended aviation fuel, and the UK is consulting on more ambitious proposals. Can the Minister update us on that?

On airspace modernisation, I know the Government have committed some funding to sponsors. When I took on the green transport brief, I was sceptical about technological solutions to aviation. I thought it was just a way of deflecting the conversation from managing or reducing demand. Having met lots of companies that are involved in this space, I now see that there is potential, although with the limitations that various Members have mentioned in terms of battery weight, hydrogen storage and the whole debate about carbon capture and storage. I have come to realise that there is more potential than I thought, albeit quite far into the future and not current enough to address the issues that we need to address today.

When I first had a conversation about airspace modernisation, I was fascinated at the extent to which straightening out air travel and avoiding a huge amount of banking, particularly above Heathrow, could make a difference. Can the Minister tell us where we are with that?

I would also like to hear the Minister address future funding for the Aerospace Technology Institute. People who are developing new technologies appreciate the funding that they have had, but will there be an ongoing source of funding? Will that be covered by the spending review? Moreover, a whole raft of airport infrastructure would be needed to support the use of hydrogen planes, so how would that be funded? That is my last question for now, although I will probably have more as I go on.

As I have said, a lot of these developments are for quite far into the future. There is potential for electric planes to be used for short-haul flights and for hydrogen-fuelled planes to be used for longer flights. I am not convinced that there is an answer for the longest haul flights as yet, but action needs to be taken now on emission reductions, and that means that difficult decisions have to be made on capacity and demand management.

The Labour party’s position on Heathrow is clear: the new runway would not meet our four tests on air quality, noise pollution, national economic benefit or our climate change obligations. That is where we stand on that.

I was pleased that we finally have the transport decarbonisation plan. I waited a long time for it and kept being told that it was due shortly. There is good stuff in it on electric vehicles and heavy goods vehicles, but it falls short on aviation. As the hon. Member for Paisley and Renfrewshire North (Gavin Newlands) has said, there are so many consultations and, while it is important to consult, they can be a way of kicking things into the long grass when we need urgent action now.

The targets to achieve net zero emissions for domestic aviation by 2040 and for international aviation by 2050 are welcome, but as the hon. Member for Brighton, Pavilion (Caroline Lucas) mentioned, they rely heavily on carbon offsetting. That is problematic for a number of reasons. Carbon capture and storage technology is by no means guaranteed to reach a point at which it can be relied on to offset a significant amount of emissions, particularly if other sectors also need to rely on offsetting. More natural carbon solutions such as tree planting do, of course, have a big role to play in offsetting emissions, but rapidly increasing rates of deforestation—whether from deliberate destruction, or from wildfires in many parts of the world—mean that we cannot rely on that either.

Back in July, I asked what proportion of carbon offsetting in aviation is expected to come from engineered carbon removal and storage, and what proportion is expected to come from natural carbon solutions. At the time, the Minister said that the Government did not know, so is he able to enlighten us further today? It is really worrying that the Government cannot come up with a response to that question, because even in its more optimistic scenarios the Climate Change Committee projects that over 20 metric tonnes of residual carbon emissions from aviation in 2050 will have to be offset elsewhere. That figure amounts to about half of the 40 metric tonnes of CO₂ attributed to aviation in 2019. With such a large proportion of emissions depending on offsetting, we need certainty about the pathway to achieving these targets, not vague projections and a reliance on technology that may not be ready in time.

I am concerned that this focus on offsetting stems from a refusal by Ministers to even contemplate demand management measures when it comes to aviation. We know that aviation has had an incredibly difficult year and a half due to the pandemic, as my right hon. Friend the Member for Hayes and Harlington (John McDonnell) has said. That is partly due to a refusal by the Government to put forward a climate-conditional support package to get the sector back on its feet, as Labour has repeatedly demanded.

Once travel rates return to pre-pandemic levels, we have a responsibility to the planet to ensure that demand does not soar to unsustainable levels and undermine progress towards reaching net zero emissions, but the Government are simply ducking the decisions they need to make in this area. In its 2021 progress report, the Climate Change Committee recommended that the Government act to ensure there is no net expansion of UK airport capacity. However, just weeks ago, the Government refused to reassess the airports national policy statement, which would have provided an opportunity to do just that.

The CCC also recommended that the Government reform aviation taxes to ensure that aviation journeys are not cheaper than surface transport, as a few hon. Members have already mentioned. However, at the moment, the only open consultation on aviation taxes is advocating reducing air passenger duty on domestic flights, in contrast with the regular hikes in rail fares. That is clearly a ludicrous prospect in the middle of a climate emergency, and it is only made worse when we read the small print and see that this tax reduction would also apply to private jets. There can be absolutely no rationale for that. Any Government serious about decarbonising aviation and setting an example ahead of COP26 would immediately scrap those plans, and I would welcome it if the Minister could explain how on earth a tax cut for the most polluting form of transport can be compatible with a trajectory to net zero. We should be investing in rail instead.

The Government have also repeatedly refused to consider a frequent flier levy to address the fact that 70% of UK flights are taken by the wealthiest 15% of the population. That clearly needs to be addressed. Representations have also been made to me about whether zero air passenger duty on zero emission flights would be one way of stimulating that sector, but I know that that prospect is some way in the future.

With the COP26 climate conference just a few weeks away, it is time for Ministers to face the facts on aviation and stop relying on vague future predictions that will simply not deliver in the timescale we need them to. The climate crisis is worsening every day. Aviation has to play its part, and I hope that today the Minister will come up with answers—things that will start to make a difference now, not decades in the future.

I remind the Minister to leave three minutes for the mover of the motion to respond.
