Examination of Witnesses (Question Numbers 180-201)

JIM FITZPATRICK MP, MR DANIEL INSTONE, MR ROBERT VAUGHAN AND MR TIM WILLIAMSON

23 FEBRUARY 2010


  Q180  Joan Walley: But, given all that, what I do not understand is why it is so difficult for local authorities to actually set up low-emission zones. Why do we not have more of them?

  Mr Vaughan: I think local authorities have different ways of tackling the issue.

  Q181  Joan Walley: Or sometimes not at all.

  Mr Vaughan: Low-emission zones might seem an attractive solution in many instances and some authorities have set them up. Obviously, London has set up its low-emission zone and other authorities, such as Oxford and Norwich, have focused their low-emission zones on a particular type of transport, buses. We have spoken to local authorities about what prevents them from setting up low-emission zones and many do quote things like competition with other authorities, the risk of displacement of pollution to other areas of their authority, depending on the size of the low-emission zone they chose, and also the need to actually negotiate that with the politics of local government as well, so many have considered them, but, as I say, they have come to different conclusions as to what the best approach is, and often low-emission zones, whilst they might be a very sensible approach in many ways, local authorities have properly determined what is the best approach at a particular time.

  Q182  Joan Walley: Can I just ask finally on this: is there anything that is being done at the moment to make local authorities give more attention to this as part of the planning process, and we touched on it, but to really make it be considered as part of the planning process?

  Jim Fitzpatrick: Well, DfT are in the lead on low-emission zones. They have a study at the moment, looking at the effect of this in Europe and working out responses to the questions that Daniel raised about whether they can be introduced, should they be introduced, what is the cost, how best are they applied, what vehicles to apply them to, so I think they are producing this data to be able to disseminate it to local authorities and to be able to give best advice to those authorities who do want to use LEZs as a way to improve local air quality, so we know that they are researching and collating that at the moment. Obviously, when that is ready, I am sure that DfT will be publishing it for local authorities to be able to look at and see if it is a tool and, if so, which element of the tool would be good for their area.

  Q183  Jo Swinson: I want to turn to the issue of power stations. Why does the UK have six of the ten power stations that emit the most NOx anywhere in Europe?

  Jim Fitzpatrick: The Environment Agency is obviously the statutory authority which has responsibility for licensing power stations. Each installation must have a permit which allows them continuing emission limit values and other conditions based upon the application of the best available techniques. As I say, the Environment Agency has to decide what they should be for each installation and, in that instance, they are the ones who issue the licence and they have to be satisfied that those requirements are being met.

  Q184  Jo Swinson: In issuing their licences, to what extent do they assess the environmental and the public health impacts of these power stations?

  Mr Vaughan: The Environment Agency carry out a full detailed assessment of all impacts a power station might have or any installation, for that matter, where they are the regulator. In the particular instance of a power station, it is determined that SCR, for example, was not economic to retrofit for the power stations concerned, the coal-fired and oil-fired power stations, at the present time and they considered that a different method of abatement was more economically viable and the best available technology.

  Q185  Jo Swinson: My understanding is that, when the decision was made not to fit them with this selective catalytic reduction technology, that was because the plants had a limited life. Is that going to be reviewed now that the working life of those plants has been extended? Will the Environment Agency now require them to fit the appropriate technology to deal with the emissions or look to closing them, or is this just going to keep going on where they will have their lives extended, pumping out all of that pollution?

  Mr Vaughan: I am afraid I cannot answer that question.

  Jim Fitzpatrick: The regulator can review the permit conditions at any time and I am advised that they will certainly do so when the best available technology reference document for large combustible plants is revised in 2012, so it is very much a matter for the Environment Agency, but there will be a requirement in due course that they will have to review the best available technology element.

  Mr Instone: It is worth noting there is, if you like, a double standard of review here. You have not only got the EU reviewing their guidance documents, which are known as BREFs, as a means of keeping up-to-date with technology; but we also have, going through the final stages of the process in Brussels at the moment, a revised EU Industrial Emissions Directive. We have got, if you like, a process of review in Europe which is rightly refining and bringing standards up-to-date to allow for changes in technology. This is not a static situation therefore.

  Mr Williamson: It is probably worth noting as well that the Environment Agency regulate within the framework of the Air Quality Directive so meeting limit values, but also the National Emission Ceilings Directive, so the national ceilings and the national total emissions. It is finding a space between those two legislative requirements in which to operate the permits.

  Q186  Chairman: Nevertheless, there seems to be a slight assumption behind what you are saying that as long as we are doing as badly as the rest of Europe everything is okay?

  Jim Fitzpatrick: I do not accept that description, Chairman. I know that we have discussed earlier in these proceedings the question from Dr Turner about whether we are satisfied that certainly because we are within a Directive then we are okay. Clearly there is an imperative to get within a Directive otherwise the discretion we had about infraction proceedings and fines comes into being; and naturally we do not want to go there if we can at all avoid at. By the same token, because of the developing science, the emerging data, the serious nature of the impact of air quality on public health, the research which is being undertaken by the Department of Health, by the Department for Transport, by ourselves, clearly indicates that just getting within the confines of Directives ought not to be our objective; we want to get to the best possible place on air quality. So I fully accept your concern clearly implicit in the question you raise. We would agree with you that we do have to do better, which is why we are striving as much as we can.

  Mr Instone: Could I just add to that also on the point about "it's okay to do as badly as Europe", or is it? The points that were made earlier about our actively influencing new Directives in Europe both in relation to emphasising the importance of PM2. 5, where we have got the very strong links with health—perhaps stronger than in any other area—we have brought that into the process of revision at the EU level; secondly, the concept that was already mentioned earlier in our evidence, about getting in the idea of exposure reduction; those are all initiatives that we have very strongly been pushing in Europe to try to make the future EU Directives more responsive and better targeted on the health impacts. That is therefore a very dynamic situation where we have been strongly influencing the way that Directives are framed in Europe to make them much more closely aligned particularly with our health objectives.

  Q187  Dr Turner: Obviously policies to deal with air quality depend to a large extent on accurate monitoring. What can you tell us about the development of air quality monitoring by both local government and central initiatives in the UK at the moment? Where are we at?

  Mr Williamson: We operate an extensive network of monitors and we supplement that using complex modelling techniques. We believe that gives us a better spatial coverage than just using monitoring. It also allows us to understand those locations where you would not otherwise have an air quality monitor. We spend a considerable sum of money every year supporting that network. It is designed primarily to serve the requirements, and the very prescriptive requirements, of the European Air Quality Directives; but it serves a number of other functions as well. It is our primary tool for generating data for research so we can better characterise and understand what is a very complex area.

  Q188  Dr Turner: Are you, for instance, able to deploy the sort of technology which exists which can identify, for instance, an individual polluting vehicle entering a low-emission zone?

  Mr Williamson: There are some technologies, remote sensing technologies, which have been developed. There is a limit to the number of pollutants that they can actually address and pick up. PM10 is a difficult one, simply because the way in which you analyse gases is slightly different from the way in which you analyse a solid particle, which is made up of a number of different components and does not behave like a gas. Those technologies do exist but they are very much for research rather than ongoing monitoring. The kind of monitoring equipment that we own and have out in the field is expected to run 365 days a year, 24 hours a day. The kind of equipment that exists to measure roadside emission plumes from vehicles is not that robust, and I do not think that would be the right use of that equipment; but there are some significant developments. There are constant developments in the field of monitoring. One of the areas that is receiving a lot of attention at the moment on a Europe-wide basis is a portable emissions monitoring system—so onboard monitoring systems particularly for HGVs; and that will be something that is introduced through the Euro VI emissions standard for Heavy Goods Vehicles.

  Q189  Dr Turner: This may seem a simplistic question, but without being able to monitor vehicles individually how can you police a low-emission zone effectively?

  Mr Williamson: All vehicles on the road are required to conform to what are called the "Euro standards", the emissions standards laid down through a series of Directives in Europe. They are age-dependent, so from a certain date all new vehicles will have to be of a certain Euro standard. By understanding how old the vehicle is, using number plate recognition technology or other systems, then we can work out which Euro standard they should conform to. Euro standards have already been introduced. Those vehicles will have been tested and there is an ongoing process of research looking at the real world emission levels of those vehicles, and that is factored into our national atmospheric emissions inventory; and that is one of our principal tools for understanding the behaviour of the emissions in question. A lot of it relies on modelling, but it is modelling very much based in real world understanding of what vehicles do

  Q190  Dr Turner: Surely if these vehicles are tested—and vehicle testing is normally an annual process—anything can happen in between?

  Mr Williamson: The testing I am referring to is not the MOT test. Again, that is a relatively limited test in terms of emissions. The kind of testing I am talking about is ongoing research undertaken by the DfT—and by others in Europe as well, so there is a Europe-wide programme—who will constantly test vehicles both on test bed, so a rolling road situation, and actually on real world driving conditions.

  Q191  Martin Horwood: First of all, Minister, gentlemen, can I apologise for being late. The reason I am late is relevant to my question actually. I drove to my local station at Cheltenham Spa to find that my train had been cancelled; I then drove to Swindon to find there were no parking spaces; and I have had to drive the entire distance to London, thereby adding to the capital's particulate matter quite considerably! What policies are being developed to encourage people to switch to alternative low carbon forms of transport?

  Jim Fitzpatrick: I think we covered some of this a little earlier, Mr Horwood, in terms of the range of initiatives and incentives that are being promoted by government: all the way through from the developing of more electric vehicles; the encouragement of hybrids; the vehicle tax incentives for hybrids and low-emitting vehicles; the Act on CO2 campaigns to raise people's awareness of their own carbon footprint and to try encourage them out of their vehicles; and the present campaign, I think, is drive five miles less per week. So there are a whole number of public awareness initiatives. There are a number of incentives, fiscal and otherwise, to encourage individuals and vehicle manufacturers to produce and to purchase cleaner vehicles. The Local Transport Act provides for local authorities to engage in contracts with bus operators; and a lot of local authorities are demanding cleaner fleets be operating within their areas; so there are a whole number of different ways that we are trying to encourage people out of individual vehicles and into more collective forms of transport by modal shift and others.

  Q192  Martin Horwood: I have to say, as a member of this Committee my awareness was pretty high, but it did not make my journey any easier. If I had tried to take the bus I think I would have been waiting all week. Are you talking to ministers in, for instance, DfT about the need to meet the kind of targets we have been talking about and the urgent need to invest in things like rail infrastructure? The recent stimulus package during the height of the recession, the same amount of money that we spent on the VAT cut could have paid for the entire backlog of rail utilisation projects in this country, could it not?

  Jim Fitzpatrick: You are tempting me to answer questions on behalf of Treasury and the DfT at the same time when we are here to give evidence on behalf of Defra, but I am quite happy to offer an opinion.

  Q193  Martin Horwood: I understand that you are having conversations with them about this in the light of the tasks?

  Jim Fitzpatrick: Forgive me, we outlined a little earlier the comprehensive nature of the engagement with DCLG, DECC, DfT, Treasury, the Department of Health in terms of dealing with air quality and a number of its different aspects. We clearly have an interest to make sure that as transport is a contributor to the deterioration or to the quality of the air that we breathe, and we are the ministry which is responsible for air quality, we have to have a relationship and we clearly do engage with them to make sure, as best we can, that the policies which they implement help us in that regard, much as they help government in an holistic approach to government policy.

  Q194  Martin Horwood: Are you happy or unhappy with the contribution they are making so far—DfT?

  Jim Fitzpatrick: As somebody who was a Transport Minister for two years, up until last July, I think I would probably say that we are happy with what is being achieved so far; but as we have been discussing this morning—and I think the Chairman said maybe I should not be too close to transport in respect of this—we can always do more. We know we can do more. We know that there are initiatives and opportunities for all government departments to improve performance on every subject, and air quality is no different. We would hope that there would be an improvement in transport's profile in respect of the impact it has on air quality; and I am sure that colleagues in the Department for Transport are working hard to achieve that.

  Q195  Martin Horwood: On my way here I drove through the London low-emission zone, but this is still quite an isolated example, is it not? We do not yet have any national framework for low-emission zones. When countries like Germany have already got them in place, are we not even disadvantaging people like our own haulage industry by giving them no incentive to develop vehicles that will comply with low-emission zones? Continental competitors might well be ahead of the game now because of the national frameworks in countries like Germany?

  Jim Fitzpatrick: Just before you arrived colleagues were explaining the various obstacles to the introduction of low-emission zones, and the fact that the Department for Transport are carrying out a study at the moment as to how best to introduce low-emission zones. There is the understanding that the London Zone is quite an expensive one to run because it operates on automatic number plate recognition systems, as opposed to other European models where they are operating on a paper-based system or a warden system or whatever. It is learning these lessons to work out what is most useful and what can be deployed to best effect to reduce the emissions and improve local air quality. In terms of vehicle manufacturers, given the trans-national nature of companies and Euro standards, I would be very surprised if we were giving an advantage to foreign manufacturers because Germany has its own. Most of these companies are producing for world markets these days, and if they know that the Euro Zone has the sixth standard coming in that would be replicated in other countries in due course; and for the 27 Member States' manufacturers it would be commonsense for them to produce to the same standard right across the board, surely.

  Q196  Martin Horwood: In effect you are relying on the Euro Zone to raise air quality by being ahead of our game?

  Jim Fitzpatrick: As Mr Instone explained only a moment or two ago, for example on PM2. 5 we are actually leading Europe and we are giving them our latest evidence and data to say this is more of an issue than perhaps it was thought before; so we are not relying on other Member States and then just cosying up to their standards. We are actually trying to lead in our own right at the same time. One of the benefits of being part of the European Union is that we do not have to reinvent the wheel on our own: we can see what is happening in other Member States, share that best practice, learn from each other and then apply those lessons to positive effect if at all possible.

  Mr Instone: It is worth adding on that, we have talked at some length about the importance—and we have given some examples—of close collaboration with other government departments in the UK; but a very key part of what we also do is to have very close contact with officials in other countries in Europe so that we can compare what we are doing and influence them even before proposals get formally tabled by the Commission in Brussels. That is an absolutely key part of what we do, to learn from each other on that.

  Q197  Martin Horwood: If that is true, and if that has been true over time, why is it that the Netherlands and Germany are so far further advanced in having national frameworks for low-emission zones?

  Mr Instone: Different countries are bound to go at somewhat different speeds, just as different local authorities in the UK are going at somewhat different speeds. I think the interesting question is it is precisely because Germany and the Netherlands (you are quite right) have introduced them more widely, because they are further ahead, that is making us look very hard and benchmarking ourselves against what they have done. It is also true that other countries in Europe, apart from those, have made even less progress with introducing low-emission zones. Yes, there is an element of variable geometry, but I think the geometry would be more variable if we were not all busily learning from each other.

  Q198  Dr Turner: Do you think government could be doing more to encourage retrofitting of things like particulate traps and other methods of reducing vehicle emissions?

  Mr Instone: We already have systems for introducing particulate traps, and that is something which, for example, the low-emission zone in London has encouraged. This is something that is under very active consideration. One of the arguments in support of low-emission zones—obviously there is a balance of advantage and disadvantage as has been mentioned before—one of the advantages of low-emission zones is that they can encourage the use of new technology, particularly retrofitting, that would not otherwise occur. I stressed earlier the importance, in improving air quality, of doing something about the existing often older vehicles in the fleet, which can be even more important in the short-term than getting new vehicles on the road. One of the things we are very actively looking at is the scope for low-emission zones to encourage retrofitment. You are absolutely right, one can take this further than simply particulate traps, so this is something that is under very active consideration.

  Mr Vaughan: Also in the past, DfT has supported reduced pollution certificates, or has issued reduced pollution certificates, which are also available for vehicles that have retrofitted to the correct Euro standard. For Euro V, they issued 39,000 reduced pollution certificates, which allowed vehicle hauliers to claim against VED for vehicles that were retrofitted or met the Euro V standard, which was about 10% of the fleet.

  Q199  Dr Turner: Which leads me directly on to the fact that the Treasury announced in 2009 that they planned to incentivise the early uptake of Euro VI for HGVs. Has this started yet, and if not, when?

  Mr Vaughan: It has not started yet because, firstly, the Euro VI has only recently come in. The Community actually incentivise once the standard is available. The actual determination of the fine detail of the standard is still yet to be agreed. The Treasury have made it clear that those standards are not available to incentivise yet.

  Q200  Dr Turner: Brake and tyre wear has been something of an intractable problem, particularly producing particulates. Has the Government got any plans to control this? What research has been undertaken to analyse the health effects of particulates from brake and tyre wear?

  Jim Fitzpatrick: I think it is fair to say that, as tailpipe emissions have decreased, emissions from brake and tyre wear are becoming of increasing relative importance, because there is more research, there is more evidence, there is more data, research advice has been conducted on options to reduce tyre and brake wear but many of these have negative effects on road-holding, so there is a lot of further work to be undertaken. The increasing uptake of hybrid vehicles will have some positive effect on brake wear as a proportion of the vehicle braking effect is translated into power. Obviously all-electric vehicles are likely to have these systems. In one sense new technology is, in itself, helping eliminate some of these emissions; but also, because of the greater understanding of the whole question of air quality and emissions, there is greater focus being given on brake and tyre pollution; and obviously that is a matter for much further research.

  Q201  Chairman: I think we have probably covered the ground we wanted to this morning. Thank you very much for coming in, it has been very helpful to us.

  Jim Fitzpatrick: Thank you, Chairman. We will supply you with the two or three pieces of evidence that came up during the course of discussions in due course.
