Select Committee on Environmental Audit Minutes of Evidence


Examination of Witnesses (Questions 280 - 299)

TUESDAY 24 FEBRUARY 2004

RT HON ALISTAIR DARLING MP, MR GRAHAM PENDLEBURY AND MR MICHAEL MANN

  Q280  Chairman: The Prime Minister said in front of the Liaison Committee quite recently that the issue of climate change is "of fundamental importance to the long-term security and stability of the world". I take it you would agree with that?

  Mr Darling: I always agree with the Prime Minister.

  Q281  Chairman: Very wise, Secretary of State! And yet the White Paper, by your own admission, will contribute significantly to the very process that is causing the problem.

  Mr Darling: Yes. I accept that whatever means you choose to use to move around will have an environmental impact. The question is what balance do you strike in terms of enabling people to move around with measures you put in place to mitigate the environmental effect of that. For example, in the White Paper it sets out a number of measures that the Government is going to pursue, whether it is greater control of emissions by landing charges or whether it is the EU Emissions Trading Scheme or continuing the argument that we need to continue at an international level in relation to aviation meeting the costs of pollution it causes; there are a number of things to be done. I am not suggesting for a moment you would advocate this, but to put it at its extreme if we simply did nothing and we said, "Okay let's just let our airports clog up," we would end up with the situation that we have in other modes of transport in this country, where successive governments of both political colours, frankly, did not take the decisions they should have done and the strains on our road and on our rail system are there for all to see.

  Q282  Chairman: That is very interesting because of course the Government have done quite a lot to draw the public's attention to the problems. In a sense, it is easier if you are sitting in a traffic jam for hours to realise the problem, but the Government has made efforts to discourage people from excessive use of their cars. To what extent have you thought of applying that to aviation and air travel?

  Mr Darling: We had this argument when I was last here in the summer. Indeed, I recall it dominated much of the proceedings.

  Q283  Chairman: I was thinking of education here and awareness.

  Mr Darling: The first point is it is not our policy to stop people from travelling. We are clear, if you take the car in urban areas for example, that we do want to encourage people to use public transport where that is appropriate, but it is not our intention to say in the extreme, "Stay at home". In relation to general education, if that is the question you are asking, my guess is that people are much, much more aware today about the environmental impact of not just travel but other emissions as well in a way that they certainly were not maybe 15 or 20 years ago. So I do not think people are at all ignorant of the effect it has. As I say, what we were trying to do in the White Paper is to strike the right balance between planning ahead for the future over the next 20 to 30 years and at the same time making sure we meet our general objective which is that polluters ought to pay the cost for the damage they cause. Things are slightly more difficult in aviation, of course, because for historical reasons taxation of aviation fuel, for example, is dealt with by international treaty. That does not apply to any other form of fuel that we consume. Of course by its nature aviation is a very international business. I think that most people in this country are acutely aware of the fact that the environment has been damaged. One of the reasons we signed up to put ourselves on a path to reduce CO2 by 60% was precisely for that reason. You need to look at these things across the piece. Each sector has got to play its part. Of course, we also need to make sure we look at other areas as well.

  Q284  Chairman: We are just very keen to help you with your responsibilities in transport to enable transport, and aviation in particular in this case, to play its part. When we find in the integrated policy appraisal at the back of the White Paper one tiny paragraph which deals with the whole question of climate change and does not make any recommendations at all or quantify the scale of the problem, might we not be forgiven for suspecting there is an element of complacency?

  Mr Darling: I do not think you should draw that conclusion. To start with there is an entire chapter that discusses various environmental implications. Of course, in addition to the appendix to which you refer, since that time, as you know, the Government has made available all the supporting documentation which is in the House Library and on the Internet and there are quite substantial documents—and I am just looking here at the aviation and global warming document which was published in January[4]—so it is not the only thing. If you have simply directed yourself to one particular paragraph, no matter what that paragraph was and no matter where it was, you would not get the whole picture but if you look at the whole picture I do not accept the general point you are making which is we did not consider the environmental impact of what we were doing.


  Q285  Chairman: Incidentally, that supporting information when we last looked was not on your web site.

  Mr Darling: It should be.

  Mr Pendlebury: It is not on the web site and actually there were some reasons for that, partly to do with the size of the files which was causing problems in downloading these things. Certainly we can make them available as widely as we can.

  Mr Darling: They are certainly available in the Library of the House, which is the conventional means of communicating them to people like yourselves.

  Q286  Chairman: They were strangely difficult to get hold of however when I tried to the other day.

  Mr Darling: I will make it my business to check and see what has happened. It certainly should be available and that is how successive governments have communicated to Members of Parliament.

  Q287  Chairman: Since you mention the supporting papers, there is this one on global warming which has already been referred to and I noticed in that the reference to ACARE (the Advisory Council for Aeronautical Research in Europe) on which you base a statement in the White Paper to the effect that you believe that aviation can achieve a 50% reduction in CO2 by 2020. Is that all that ACARE said?

  Mr Darling: No, but I think the statement in the White Paper was right. Are you saying we misquoted them or something?

  Q288  Chairman: With the greatest respect, it was not right because what they also said was that "the 2020 targets would not be achieved by developments for the current engine architecture and that more radical changes will be needed". They went on to say: "To maintain the same rate of progress as today to 2020 and beyond will require break-through technologies and consequently higher-risk approaches" Do you have any idea what kind of technologies those may be?

  Mr Darling: It is not our position that any one thing is likely to achieve the target but in sum they will help do that. As I think I said to you in the summer and I say to you again today, clearly there is a formidable challenge in reducing the emissions and dealing with the effects of aviation. I made the point about having to strike that balance between people's needs and doing that. If you take engine technology, for example, there is no doubt engines are much cleaner than they were 25 or 30 years ago and quite recently the industry signed up to a further reduction in the amount of nitrogen dioxide they use, but you would not rely on engine technology alone to achieve your ultimate objective. There is a whole range of things.

  Q289  Chairman: There seems to be a degree of scepticism within the industry about these technical developments which are supposed to be going to happen to enable the impact of aviation on climate change to be reduced. I have got something here from the Royal Academy of Engineering who also refer to the ACARE study and they say: "It is not yet clear what form these new technologies might take, but without such advances it does appear that if growth in aviation continues"—which of course it will under your scheme—"the contribution aviation makes to global warming is likely to rise." How do you square that statement with what you actually put in the White Paper? What you did was refer to ACARE and said they say you can get a 50% reduction by 2020; that is simply not correct.

  Mr Darling: We are not saying because of improved engine technology the adverse effects created by increased aviation will be sorted out. What is undeniably the case is that engine technology has improved but there must come a point where with all the improvements in the world you cannot go that much further. Some way down the line if we move to hydrogen fuels there might be another step change, but that is really beyond the time-frame that we are contemplating here. As I say to you, what we sought to do was to strike that balance that I have referred to and all the information is available, and this has been a pretty open process and people—you noted yourself—can get at what the information is. My argument is not that aviation is not a problem in terms of emissions and clearly there are things that need to be addressed and things that need to be done—and you are almost coming at this from the point of view (and it may be simply your line of questioning, I do not know whether you believe this) that the answer is that we should either stop flying altogether or stop it where it is or whatever. I think that approach would not work either. The correct approach, in my view, is to look at all these problems and try to sort them out problem by problem. Some of them are more difficult to solve than others.

  Chairman: Just for the record, I can assure you that I do not think anyone on this Committee is talking in terms of stopping people from flying or halting aviation in its tracks, that is not where we are coming from at all, but we are concerned about the proposed growth trajectory. That is what we are interested in and seeing how we can mitigate that.

  Q290  Mr Challen: Can I follow on from that with a question about technologies because in this paper, one of the 27 that supported the White Paper, at the end in Annex E it virtually rubbishes all the other technologies that have been mentioned. Hydrogen, for example, would have many disadvantages, biofuels are too difficult, and on fuel emissions the RCEP[5] finds no serious suggestion of really major change in engine design for the foreseeable future. It does not go into others, perhaps a few improvements will be found, but there is nothing to substantiate the idea that technology, as in George Bush's imagination, is going to save us from the consequences of great expansion in consumption. Where are these technologies that are going to help us out of this fix?

  Mr Darling: We did not, as far as I am aware, consult George Bush when we drew up these proposals.

  Q291  Mr Challen: It is his policy.

  Mr Darling: In relation to technologies, as I was saying to the Chairman, I think we can over the next few years look forward to a steady improvement and more efficiency. What I was saying to him was in terms of a step change to something radically more efficient and less environmentally damaging, like hydrogen fuel cells for example, for cars we reckon that is at least 20 to 30 years off and for aviation my information is that it is probably longer than that. For us to have predicated our argument on that new technology or something radically different being available on a much closer timescale would have been misleading. Nobody is in the business of rubbishing technological advances. Indeed, I think I made the point during my statement to the House on 16 December that there had been quite substantial advances made in that engines were much "cleaner" than they were, say, 25 or 30 years ago.

  Q292  Mr Challen: Might I suggest that one alternative that has not been looked at here is the issue of dirigibles where you do not need runways and you do not need airports. This has not been looked at, and perhaps it might be laughable but it is a technology that was used unsuccessfully at first but it has now seriously developed and there is no mention anywhere in the White Paper, as I recall, of that technology that could perhaps fix many of the problems faced in the context of global warming. There is a major gap and I hope you could give a commitment perhaps that that would be looked at in the near future?

  Mr Darling: All I would say to you is at the moment most people who fly tend to fly in what you might call a conventional aeroplane.

  Q293  Mr Challen: So we cannot possibly approach their behaviour and try to manage it as we are trying to do with cars? A lot of people in cars do not like public transport but we have to tell them that there are alternatives. Could that not also be applied to aviation?

  Mr Darling: Up to a point. For example, within the UK within this country, as I said to you when I was here in the summer, I think there are very powerful arguments for people choosing to travel by train as opposed to aeroplane, particularly in England where when the West Coast Main Line upgrade first stage is finished this year, the journey time between Manchester and London will be just about two hours. That is much, much more attractive than going out to Manchester airport, flying down to Heathrow and coming in, whereas in the past two or three years, when the work has been going on, people have said it is quicker to do the flying. Obviously in a whole number of ways it has improved so they could take the train. Similarly, since the Channel Tunnel Rail Link first stage was opened in September, it has seen a dramatic increase in passengers and when I last checked this the Channel Tunnel Rail Link had 60% of the travel market between London and Paris. This is an example of where people do have a choice and do have alternatives. When you are talking about people flying to America or the Far East it is less easy to see (certainly with America) what alternatives there might be. I am certainly not against choices, I am not against new technology as and when it comes along—you would be absolutely mad to be against that. What I think, though, the Government has a duty to do is to, as it did here, to look ahead over the next 20 to 30 years and say what is likely to be around and what is the correct response to that. As I said right at the start, people can have different views on that. Simply because you look at an argument and say, "Well, I am not entirely convinced by it", that is not to rubbish it nor is it to turn your face against things that might happen in the future that might cause you to take a different approach.

  Q294  Mr Challen: I will have to look at the Department's web site and see if there is any work being done on the form of transport I have just suggested which could be very suitable for short haul journeys in Europe and cause far less climate change damage than perhaps the conventional form of air travel. The Department has predicted a three-fold increase in passengers per annum compared to what we have now; 180 million now to 500 million passengers per mile (mppa) in 2030. The White Paper is trying to satisfy 470 mppa. That rather suggests that you are just predicting and providing but this is not something which you have really accepted you are doing, is it?

  Mr Darling: No, I have never accepted that argument. Let me just set out our approach to it. Firstly, my view of predict and provide is you are building runways on spec. You are saying, "Let's build them and we hope they fill up."

  Q295  Mr Challen: You would need a business case to do it, would you not?

  Mr Darling: Remember that unlike the rest of public transport, the aviation infrastructure is to be built by the private sector not by the Government, so whether it is Stansted, Heathrow, Birmingham, Edinburgh, wherever, it is going to be paid for by the private sector. If you take the South East of England you have a situation where already Heathrow (certainly), Gatwick (approaching) and Stansted (rapidly) are reaching capacity. We are talking about building a runway at Stansted which will not be ready until the beginning of the next decade and at Heathrow there are big environmental issues to be sorted there. I hardly think it is fair to accuse us of predicting and providing in the South East. In the Midlands and Scotland what we have said is if our predictions are right this is what we think may be necessary. Remember this is a framework document. It is not saying you are definitely going to get all these things, there is still the need for planning permission of course, but what we are saying is this is the framework, this is what we think might be necessary and we will proceed accordingly. If, for example, the demand did not materialise or people found different ways of travelling then they would not build these extra runways because there would be no commercial case for having done them.

  Q296  Mr Challen: I assume that the Department's research that led to this prediction has been based on some solid appraisal. At what point of growth would the Department find it unacceptable, would it be 600 mppa or 700 or 800? Have you drawn the line here? What happens if it exceeds those predictions?

  Mr Darling: No, our approach was to look at all the information we had, to set out what we thought might happen. We consulted, as you know, for over a year. The general consensus was that our predictions on the information we had were probably about right. Where there was clearly a difference, there were people who responded to us to say, "Yes, this may be right but we think you should do things to stop it rising that far." There were one or two who said they thought even more people would fly. My approach on this was of course I looked at these predictions and of course I looked at the pressures we are likely to face, but a lot of my approach was driven by the fact that you test those predictions against what you can see happening in different parts of the country. If the figures do not work out that way, if the demand, for one reason or another, does not look like it is going to materialise, then the runways will not be built because nobody is going to put up that sort of money. Building an extra runway and terminal capacity is extremely expensive.

  Q297  Mr Challen: If nothing else is done and there is a further increase in cheap fare traffic then clearly growth could go through the roof. The integrated policy appraisal appended to the White Paper refers constantly to the Government "encouraging" growth, so clearly you want to see more growth. It is not so much predict and provide, it is promote and provide, is it not?

  Mr Darling: No. The Government certainly wants to see economic growth and the Government wants to see people increasingly become better off and more prosperous, and the consequence of that is they will probably want to travel more for business and for pleasure. Obviously, it is in our interest to provide people choice where that is appropriate, and I mentioned for example what you can do within the UK, but I sometimes find that predict and provide is used in a pejorative sense by people who think you should not be doing this at all. I really think generally the approach we have taken is a reasonable one given the pressures that we face. That is not for one minute not to accept the extremely valid points that are made by you and by other people about the fact we have got to have regard to the environmental impact of flying. The two things go together, they are not distinct. Of course people who do not like the policy anyway will seek to rubbish us and say, "Of course they did not consider the environmental impact"; that just is not right.

  Q298  Mr Challen: I draw a distinction between predicting something and promoting something and this White Paper seems to encourage and promote growth in air travel. It does not do anything to limit it. I do not see very much in the White Paper that actually seeks to manage this growth. We have seen the consequences of predict and provide in road transport, which we are now trying to manage.

  Mr Darling: Unfortunately, we did not do too much predicting or providing in road transport.

  Q299  Mr Challen: Unfortunately we got it wrong. I dare say all the predictions were exceeded by the actualities, and that could well happen here, so what is the Government doing to try and restrain that growth so that the growth in aviation and particularly carbon emissions does not sweep out of the whole arena everything else that the Government is trying to do with climate change to reduce the UK's emissions.

  Mr Darling: Our policy is not to stop people from travelling. You mentioned the roads for example, and I think again successive governments either did not predict or due to various restraints chose to ignore their predictions and they certainly did not provide. That is one of the reasons that we have so many congested roads. Our policy must be to enable people to move around and to travel but to do that in a way that takes account of the environmental consequences of that. I know because we spent a lot of time (which I do not propose to go over again, especially since the Chairman has assured me in relation to your own beliefs and intentions) in arguing these things last time, but our policy is not what is crudely termed "demand management". I know you have heard quite a lot of evidence on that fairly recently. Where I think we do need to do more is in areas that were set out in the White Paper in relation to the charging depending upon the emissions of individual aircraft, the European Union Emissions Trading Scheme and to continue the argument at international level because that is where these things are governed about the need to make sure that aviation, like everything else, meets the cost of the pollution it causes. That is a more fruitful way of going rather than saying let us try and limit the number of people who fly and therefore the number of aircraft that are in the sky.
