Select Committee on Environmental Audit Minutes of Evidence


Examination of Witnesses (Questions 140-159)

MR TIM HELWEG-LARSEN, MR PAUL ALLEN AND DR DAVID FLEMING

17 JULY 2007

  Q140  Mr Chaytor: So you are saying that you need other measures in addition to the tradable energy quotas?

  Dr Fleming: No, that is intrinsic to it.

  Q141  Mr Chaytor: You have referred to the carbon budget.

  Mr Helweg-Larsen: If I might take up that point, we started off by saying, "What is the carbon budget for Britain?" That carbon budget is a budget over time but it has a budget every year and within that right down to the week. Those weekly budgets are going to be distributed under the TEQs scheme; 40 per cent is going to the domestic sectors and 60 per cent is auctioned to business and industry. That budget, on a weekly basis, is contracting week by week and business and individuals will have great confidence in the profile of that reduction because it will be defined by a carbon policy, much like the Monetary Policy Committee. We would know that right from the outset. There is the possibility to adjust that budget, maybe on an annual or five-yearly basis, in the light of changing climate science and what have you. In terms of how you achieve the reduction, you achieve the reduction because you decide what reduction to achieve at the outset.

  Q142  Mr Chaytor: I am still unclear how the TEQs themselves will result in ...

  Mr Helweg-Larsen: We have a budget each week—

  Q143  Mr Chaytor: Yes. It may be somebody else needs to pursue this line of questioning. Can I move on to the question of technology. Earlier you drew the analogy with the Oyster card, for example. Accepting the Oyster card works pretty efficiently in my experience but the difference is surely that the Oyster card is voluntary, that not everybody who travels on the London transport system has to have an Oyster card, whereas for a successful tradable energy quota system, everyone would have to be part of it.

  Mr Helweg-Larsen: The underlying question is how do you "force" my gran to take on a carbon Oyster card when she might have no interest or what-have-you?

  Q144  Mr Chaytor: It is a question of the scale of it also, is it not? We are talking about 60 million plastic cards as against 500,000 or so.

  Mr Helweg-Larsen: Indeed. A carbon Oyster card is visually quite an easy way to grasp the TEQs concept but in practice you might find that it is far more seamless than that. It does not need to be so obvious. It could very well be—I think you would back me up, David—that if you have an existing credit card or debit card, your bank might be very keen to provide you an extra service and have the carbon data kept on that very same card. If you choose not to engage in any of this carbon trading at all, you could elect to have your tradable energy quotas cashed in the moment they reach you and so you just operate in a cash economy and the vendor of fossil fuels would charge you extra for the TEQs that they have to purchase.

  Q145  Mr Chaytor: On the question of the role of the banks or suppliers of the card, you referred to a carbon card, not an energy card. What other infrastructure would be required to enable the banks to be able to offer that service?

  Dr Fleming: The infrastructure is minor, in my view, in that the cards would not actually have to have anything except your account number, which would plug into the registrar. This is designed based on a system that has existed for many years of unit trusts. When you buy a unit trust, your holding is held in a central registry in an electronic way in exactly the same way—I used to work in the unit trust industry—and exactly the same system is used for this. All you do when you have a credit card, you access your account on the registrar and it is transferred. That is really very simple. It may very well be that the banks want to provide some ancillary services and indeed, there would be some services they would provide. For example, the tender, which of course is very well established for the issue of Treasury bills, as you know, would in exactly the same way as is used for Treasury bills, trickle-down purchases made by the bank on behalf of their customers into customers' bank accounts. Those accounts would have to be set up but that is very standard in accounting systems, so setting up another account for people is just like setting up a savings account. So in fact, the technology is really very straightforward.

  Q146  Martin Horwood: If you have this account running, what happens when you have used up your quota?

  Dr Fleming: The thing is that one needs to be aware, even though Tim quite rightly said that it is issued week by week, actually, on the very first day one year's supply of carbon release is issued, so in fact there is constantly a one-year supply in the market as a float, so it is extremely unlikely that anybody would actually run out, but they may run out and, if they do run out, it is like going to a petrol station to buy your petrol. You have to surrender a certain number of units if you have run out of units or you have forgotten your card.

  Q147  Martin Horwood: If it is likely to run out, how is it going to change behaviour?

  Dr Fleming: What they do is they buy units on the market on your behalf and so you surrender units. The answer to your question now is in a way, there is a misconception unfortunately which Nick Eyre rather produced, i.e. when you run out, you go into the market and buy some more. That is absolutely right but the point, the crucial point is that the market is subject to that quantity constraint, is subject to the budget, so collectively, the economy as a whole cannot possibly go beyond the budget, and one needs to recognize that this is a guaranteed scheme; it is impossible for the economy to use more units.

  Q148  Chairman: As you will know with your experience in the investment world, if someone has sold short, you get the most enormous price spike. If there is a quantified total available and someone is short, they have to get their pregnant wife to hospital by filling up the car with petrol, the price could be infinite because there is no supply in the market. I do not want to get too bogged down in details but your answer there, I do not think, really stands up to scrutiny.

  Dr Fleming: Not at all, sir. The price of units is posted on petrol stations in the same way as the price of petrol and if for some reason they were to charge a lot for their units, the price would be on display, and you could just go round to the nearest hole in the wall and pick them up there. One needs not to imagine that the world is full of wicked monopolists.

  Chairman: It sounds like the former Prime Minister saying, "We will march the offenders to the nearest cash point."

  Q149  Colin Challen: The popularity of the proposal is in some doubt because Defra apparently has produced opinion research which suggests that 70 per cent of the population are either not very keen on it at all or may not be terribly interested and if you look at David Miliband's blog, you will see there is a great deal of hostility in many of the comments that are posted. Given that it can be quite difficult to have a pilot scheme some other kind of evidential base up front to demonstrate it is quite a good idea, how can you get round the public scepticism about this proposal in practical ways?

  Mr Allen: The fundamental thing is to get across that the lifestyle changes that people will have to explore are really related to our bad attitude to energy over the past 30 years and the failure of markets and governments to foresee what the consequences of climate change would be. That is going to cause lifestyle change, not tradable quotas, and you have to get that shift in. There is going to be some unpleasant medicine regardless of which type of medicine we take and the displeasure at the taste should not be related to the medicine that is chosen but to the illness. Once that is instilled in society, the question of what techniques can be used to resolve this situation most equitably would produce a different response.

  Q150  Colin Challen: It is a challenge for the government to try and prevent the unpleasantness from happening by introducing far-sighted, radical policies such as this perhaps to head off a crisis but until we have the crisis, as you say, perhaps people will not be so keen to engage with the policy. That is the conundrum that we have to resolve.

  Mr Allen: The first scientific musings about carbon emissions were 100 years ago and if we had had the foresight in the 1950s and developed along a different technology line, we perhaps would not be in this situation now. It is essential to separate the actual tradable quotas from the bigger problem.

  Q151  Colin Challen: How do you sell the policy as a positive product to peoples whose backs are against the wall?

  Mr Allen: We also have to look at what other changes we need to make in society. We need to change people's health, we need to change people's diet, we need to change people's levels of fitness, we need to improve levels of social cohesion and community purpose. There is also a big need to deal with personal debt. If some of those can be instilled as additional benefits of re-thinking our attitude to energy, there are additional benefits we can explore.

  Dr Fleming: May I pick up your point about motivation? I have five points and they may all be significant. Number one is a piece of research on motivation in Canada, particularly with old people and they are now extending it to the population as a whole, which shows a bimodal result. When they say, "What you think about the idea tradable energy quotas or personal carbon allowances?" they say, "No, not on your life. What a terrible idea." Then they have a discussion and talk about why they may seriously be needed and why they are the best solution, and the reaction changes completely: "This is absolutely right, and not only that, we will show other people how to do it." If it is well expressed, there is a complete flip in opinion. That is the first point. The second point is that we do need to recognize that there are these energy problems and if we are—and I think it is a matter of when we are—in an energy crisis, people will be on their knees for a rationing scheme. They may call it an entitlement scheme or whatever but if you have a rationing scheme, you can guarantee that when you want to buy your petrol, it will be there for you and it has your name on it. Without a rationing scheme people will be in trouble. The third point is when people say, "What would the effect of this scheme be? What will people think about it?" one absolutely has to say it depends on how steep the carbon budget is. If the carbon budget was hardly doing anything at all, it would actually have no effect on our lives whatsoever. So the whole effectiveness of it, the whole reaction of it, depends on the steepness of that and there will need to be a clear communication and interaction between the Carbon Policy Committee and the economy and people as a whole, working out how steep they can make it. There is no sensible answer to motivation and what people's reaction will be unless one specified the budget. The fourth brief point is that this will be a wonderful opportunity for the government really to do a useful job and to be on our side, because the Energy Policy Committee are the nasty guys but the government becomes the nice guy because the government is also part of the scheme; they too have to buy their units and therefore the government is not say "We are going to impose this taxation, this regulation, and if it is not hurting, it is not working." They are going to say, "We are all in this together and we are going to work with you on enabling you to actually achieve this." If someone is in trouble because they only have a three-bar electric fire for an enormous stone-built house, okay, we are going to help you in whatever ways come to mind, with money, with technology, with help and advice, in whatever ways come to mind so that the government is part of the scheme so that actually means there is a sense of common purpose. Finally, it is a sense of at last there is something to do; we can do something about it. I think one of the reasons why there is a reluctance to accept the climate change problem and the energy problem is that people do not know what to do about it. There is the law of reverse risk assessment: it is much easier to recognize a problem if you think there is a solution and if people say, "Yes, not only do we have this problem but we also have this solution" that could be fantastically popular and, as Tim said in his excellent report, it could even be a vote winner.

  Q152  Colin Challen: The zerocarbonbritain report does foresee this scenario of a steep reduction in carbon emissions, which obviously affects our habits in relation to the use of energy but how steep can it be to be publicly acceptable? If you have a very steep curve downwards and that means the price of carbon rises very quickly, I would assume, people might be tempted to say, "Great! We have a windfall. We will go out and sell our units straight away," and obviously they may then learn there is a price to pay later on. If we did not have a steep curve, that might have greater public acceptability because, as you were saying, you could start off flat and it would not have much of an impact until you get the system embedded. What is the optimum curve to introducing this?

  Mr Helweg-Larsen: I think the first thing to say is let us look at this as an emergency and, if this is an emergency, the public needs to understand this issue as an emergency and then our actions can be framed by that context. One of the things that I found quite invigorating and uplifting as we came to the conclusions of the report was that we did not when we set out know what carbon reduction we were going to be arriving at. We had not done all of our reading on the climate science at that point but as we worked on through it—and I am going to digress briefly into climate science—two key things came out. One is that we now understand from the contributing authors of the IPCC that there are numerous and very powerful feedback mechanisms in climate change and that this is leading us to an understanding of climate change. If we look at it as an explosion or as a bomb, the carbon emissions and our greenhouse gas emissions are much more of a detonator. The feedbacks represent far more the main charge, so there is this new perspective that we are just on the trigger really of this bomb. The second is that, because the atmosphere is cumulative in its concentrations of carbon dioxide and greenhouse gases, and because we are starting to realise that there may be significant sink failures to pulling those emissions back out and that the sinks do not grow at the same rate as our own emissions, it may be that we cannot add any more to the cumulative concentration of atmospheric greenhouse gases. It may be that we absolutely cannot add to that, and that means not emitting; that means zero carbon emissions, so it is zero carbon emissions probably yesterday. How fast? It is what I was touching on at the beginning; we need to frame it in that context and then, if we see that we are going to zero emissions, it puts a very different perspective on it than thinking about a 60 per cent cut or an 80 per cent cut or a 90 per cent cut, which just seems more and more constrained and impossible and you get to a 100 per cent cut and you say, "Am I dead yet?" The answer is no, there is life beyond carbon and it is quite refreshing to start exploring just what we can do.

  Q153  Colin Challen: That makes very clear the nature of the emergency, which I think most of us in this room would agree with, but most of the people out there have a different idea, as perhaps evidenced by the polls that you referred to. A radical measure would not be welcome so the question remains politically how do you get from A to B and how do you sell the idea as a positive, good thing for people to engage with?

  Mr Allen: I think Britain has a network of museums, galleries, science and discovery centres which are not engaging with this issue at all, and we have a National Curriculum which touches on it but does not really get to the core of what Tim has just said. If we can get the attitudes to the problem out there to be the same as the attitudes to the problem in here, then we have a fertile ground for introducing some sort of equitable system for dealing with it. The optimum carbon descent steepness curve is the one that begins immediately. The longer we leave it, we are moving away from the optimum because we are making the descent steeper and steeper, and therefore the social transition harder.

  Q154  Colin Challen: Your memo has suggested that there should be an independent body created called the Carbon Policy Committee. I wonder if you could just say what differences that might have in comparison with the Government's proposal in the Climate Change Bill for a Carbon Committee.

  Mr Helweg-Larsen: I think under the draft Climate Change Bill the committee that is envisaged is similar in name, but very weak in structure. It is nothing like as rigorous or as independent or as powerful, I suppose, as the Monetary Policy Committee that we have today or the Carbon Policy Committee that is envisaged.

  Dr Fleming: Is it permissible to answer your previous question?

  Q155  Colin Challen: Sure, with the permission of the Chairman.

  Dr Fleming: The question was what would happen if the budget went down so steeply that the price rose and that would encourage people to sell, and there are three brief answers to that. The first thing is that the price absolutely does not matter. One of the fundamental rules of system design is that if there are two variables, one only has one degree of freedom. That is to say, if we have two variables, one is quantity and one is price, but it is only quantity that matters. Price can be flexible and it is because of that flexibility that the system works. It applies to any system. Lots of people do think, "Oh dear, supposing the price fell very low, the government would have to intervene." The price is completely irrelevant. It is entirely the quantity that matters. Because of that, the system provides a guarantee. The second point that is relevant is that we may well under-estimate the extent to which the political economy is able to reduce our carbon emissions. Terry Barker at Cambridge has done some interesting work on that and described something called "the announcement effect". The government does not even need to impose an instrument; all it has to do at the very start—I am not saying it is a substitute—is just to announce it and immediately there is clear evidence that people are reducing their energy demand. So in fact there is a substantial degree of softness in the economy and I think we would be surprised, certainly in the early years, how much the economy could actually respond when the energy availability goes down. The third point is that a steep carbon budget would have lots of very clear benefits. One clear benefit is that it would enormously improve our security because, as energy gets scarcer and as the agenda for climate change becomes more severe, any economy which is already a long way down in terms of their energy consumption will have an advantage. They will be more secure, they will have a competitive advantage, they will be less liable to disruptions. Clearly, all the motivation is towards a steep carbon budget.

  Q156  Martin Horwood: If that steep carbon budget happens, is there not a risk? You say quantity is the thing that matters and price is irrelevant but price will have a huge impact on individuals. You can imagine a scenario in which rich people see the way this is panning out, fork out on all the photovoltaics, put ground source heat pumps in their swimming pools, they buy a brand new car which has a zero carbon footprint, and they use what of their quota they do not want to sell to pay for their holiday because that is the only way you will be able to afford it under this steep carbon budget. Poor people find themselves with a bit of cash if they have a relatively low carbon footprint are actually also trapped in houses and with cars and lifestyles that they cannot change because of that need for capital expenditure. So they end up perhaps with a bit of cash but unable to travel in the way that they could, probably unable to afford a holiday because the TEQs required will be beyond their means. This could be a very unequal system in the way it actually pans out.

  Dr Fleming: I do not think I can really bear out that argument, for two reasons. One is that the higher the price, the greater the motivation there is for the poor to in fact reduce their carbon emissions and the more money they will get in when they can sell their surplus rations. One of the things which will be intrinsic with this will be that the government, which, as I said earlier, will be the good guys, would enable the poor—it would be an absolute priority—to reduce their carbon emissions and it will have enormous effects such as location of shops and location of jobs versus living.

  Q157  Martin Horwood: I am sorry to interrupt you but that is new development. Most people have to exist in the world that exists now, where their shops are now and the way the housing estates are designed now. I can afford to put solar thermal panels on my house to reduce my carbon footprint but most of my constituents are not going to be able to afford that.

  Dr Fleming: That is music to my ears, Mr Horwood. You are completely right. I am talking about transition here. The carbon budget goes down steeply but gradually, that is to say, there is a transition. It is hard to define in terms of words what it is. If one immediately has a one-step crash in the carbon budget down to nothing, which could indeed happen from the point of view of the energy market, but leaving that, if there were a one-step crash, then indeed there will be a one-step crash in poor people's behaviour but, as well as talking about a transition and as well as talking about this common purpose and this collective motivation, the thing does become really a matter of working together, and far more likely than your appalling scenario of the rich people getting into their Jaguars and driving to Spain or whatever it was, it is much more likely that there will be some communication between the rich and the poor.

  Q158  Martin Horwood: My point was that rich people can afford to buy their way into a low-carbon lifestyle in a way that poor people cannot because their lifestyle choices are much more constrained. They might end up being the losers. Although they are relatively low now, they might end up relatively high.

  Mr Helweg-Larsen: Perhaps I can respond on this. You are pointing out that there are going to be households who do not have the disposable income to switch to energy-saving appliances, that do not have the disposable income for insulating their lofts and, as the carbon budget shrinks week on week, they are going to find themselves in the position where they actually have to purchase extra TEQs on the market. Yes, absolutely. The scheme provides us with a core driver out of carbon in a race out of carbon. It does not fill every last nook and cranny. Not wanting to be derogatory, it does not solve all the world's problems but built into the scheme, given that 60 per cent is being auctioned to business and industry, if the price were to go high, to the extent there is value to these tradable energy quotas, there is a significant income to government to work with those groups which would be most disadvantaged and so there is going to be significant funds. There is also going to be an obligation on government to provide secondary legislation and to find all sorts of interesting ways to back that up. We have to prioritise the primary problems of climate change and access to fuel at all, and recognize that there is going to be no equity in a climate change disaster and there is no equity in a situation where fuel is completely unavailable to anybody.

  Q159  Martin Horwood: Two final questions. Why are children not included and why weekly allowances?

  Dr Fleming: Everybody is included, including children. Children are just included in a different way, that is to say, there could be changes to the family allowance and such things. The idea of someone as soon as they are born qualifying for a full adult version of the TEQs ration seems to me bizarre. The point is the scheme has a core. One can talk about the hard core and the periphery. That is peripheral. At the moment it is designed so that children are included through family allowances and then they get their adult ration at the age of 18.
