Examination of Witness (Questions 200-219)

PROFESSOR LORD STERN OF BRENTFORD

11 MARCH 2009

  Q200  Richard Burden: I would like to ask you to say a little bit more about how you see growth. You have been very clear in saying you are low carbon growth, not anti-growth per se, and you have always made the point that you do not see there being a contradiction of development in the pro-poor growth and low carbon growth. I would like to press you a little bit on what you mean by that, because there are a number of commentators who say there is actually a conflict there. Either environmental objectives do not get pursued enough and, when it comes down to it, in the development context fairly traditional models of growth are pursued or, on the other side of the argument, that because there is not a framework being developed of what low carbon growth actually means in a development context, you could end up with a form of growth that will not actually be very poor. Do you still think that the two things can be mutually reinforcing: development, pro-poor growth and low carbon growth, and, if so, how? What are the things we need to do? What is the framework we need to develop them?

  Professor Lord Stern of Brentford: I think we have to do both at the same time. The two big challenges of this century are the fight against world poverty and the management of climate change, and they are inextricably interlinked. If we fail to manage climate change, we will undermine development very drastically, and if we try to put forward a programme for the management of climate change which is seen to, or does, undermine the prospects of fighting poverty over the next 20 or 30 years, we will not succeed in gathering the coalition that we have to and neither would we deserve to succeed. So from those very basic perspectives, we have to find it. Can we find it? Yes. A lot of this is about doing things in different ways which have their own attractions from the point of view of development. A lot of the low carbon sources of energy, if used on a major scale, would give us a form of growth which was cleaner, quieter, more energy secure and more biodiverse. The kind of growth path we are talking about is very attractive, for reasons which come through actually rather sooner than those associated with the management of climate risk, although, of course, the management of climate risk is enormously important. The question is: how do we manage the transition from here to there? There will be some costs along the way. I do not want to pretend that we can switch over from a high carbon growth story to a low carbon growth story without incurring some investments involved in managing that transition. In the medium term, over 20 or 30 years, there will be some investment costs as we learn and as the costs of action come down. Because the technologies are changing very rapidly, the more we put into them the more rapidly those costs will come down. The policy here is about getting between where we are now and the low carbon growth path which is so attractive, managing the costs of that transition and seeing how to do it in a way that makes the most of the growth opportunities that are there.

  Q201  Richard Burden: That is helpful. One of the things I am trying to get at, though, is how we can try to make sure that in making that transition in practical terms—not in theory, but in practical terms—that the burden of that does not fall on the poorest and most vulnerable, whether it be in the least developed countries or actually parts of the population that may be middle income countries. What are the things we need to be doing to make sure that they are not the ones that are suffering?

  Professor Lord Stern of Brentford: We need substantial finance. There will be important mitigation investments that need to be made, and in some cases in the short run, and in some places, they may cost more than the others. There will be places where wind power, solar power, ground source heating and geothermal, at least in terms of investment costs early on, cost more than a coal-fired power station, and what we have to do is to come up with incentive and financing mechanisms so that people in the developing world are financially supported to make those changes. Adaptation, what I prefer to talk of as development in a more hostile climate, is expensive. When we worked on the Millennium Development Goals, and I was involved as Chief Economist to the World Bank in the Monterey Conference on Financing for Development in 2002, and I directed the writing of the report on the Commission for Africa which reported for Gleneagles, so I was there and I know, we did not take climate change into account as, in my view, we should have done, even with what we knew then—we know more now—and we have to recognise that, had we taken it properly into account at the time we did those 2002 numbers for Monterey and the 2005 numbers for Gleneagles, we would have come up with higher numbers. The Human Development Report estimates around $85 billion a year by 2015 is the extra cost of moving towards the Millennium Development Goals in the context of a more hostile climate brought about by climate change. So resources are very important here, and they are not small. I wanted to emphasise the advantages that come with them beyond simply managing the risk of climate change, and there are many others I could go on to in terms of the empowerment that comes with being not directly dependent on a grid, and I have worked a lot in rural India and urban India. You would not want to be dependent on the grid because somebody has got their hands on your switch, and not just India but many other countries around the world. There is some empowerment too which comes from being independent. So this has quite a lot of different aspects to it, but, basically, there will be some investment costs up front in mitigation where we have to find financial mechanisms, often market mechanisms, to help supply those finances, and we have to recognise that the numbers we were talking about on development support are too small when you look at the challenge of development in a more hostile climate, or adaptation, as it is sometimes called.

  Q202  Mr Singh: To what extent should developing countries now be building resilience to climate change into their development plans, and, if that is what they should be doing, what are the steps that they should be taking?

  Professor Lord Stern of Brentford: I think it is crucial that they do, because it makes no sense to make your plans in the context of an assumption that the climate will be like it was in the past when it is not going to be like it was in the past; so I think there is no alternative to bringing it in. The first thing you need is information. There are no certainties here, but you need information on the probabilities of different kinds of outcome. It looks as if south-west Africa is becoming much dryer and south-east Africa is becoming much wetter—looks as if—and what we want is those who are concerned, and obviously, in the first place, the people who live there, to try and understand as best they can what the different likelihoods are—we are not going to do better than probabilities, but what the different likelihoods are of those different kinds of changes. You cannot plan agricultural extension, you cannot plan an urban sewage system, you cannot plan an irrigation system without some knowledge of the different kinds of possibilities that there would be, so that information story is absolutely crucial, and we have very good climate science research in the UK—outstanding. I am not a scientist, I am just a consumer of the science, but I think investment in the climate science in the UK, because you need the global model, because it is a global system, of course, the climate and the weather, whilst at the same time supporting observation stations, supporting local modelling of particular aspects of the climate in a way that can integrate with these global models. The Hadley Centre is working in that direction. I would say more power to their elbow, because without that information it is very difficult to make the kinds of investments that are necessary. With that kind of information, and we are going to have to guess as best we can now, we cannot wait for it all to be refined because the investments in irrigation, agriculture extension, and so on, come now, the investments in urban infrastructure come now, so we have to try to think how best to use that information as well, and, thirdly, we have to recognise that development, as I said before, in a more hostile climate costs more and they will need extra support for that.

  Q203  Mr Singh: Are we clear and are developing countries clear about the adaptation measures that are required and the costs of adaptation measures, and how are the donors working with the governments of developing countries to build that into development plans?

  Professor Lord Stern of Brentford: Increasingly developing countries are doing their best to understand the implications for them, and that is why I emphasise so strongly the information side of this story, and there is great variation. The number of observations that you have for Ethiopia are tiny compared with the number of observations you have for, say, France. Take countries of comparable size and population: if you look at the most vulnerable point in the world in terms of its consequences for human kind, it is probably the few hundred square kilometres in the Himalayas that feeds the Yellow River, the Yangtze, the Brahmaputra, the Ganges, the Jomuna and the Indus—if you go round, that is where they all start—and the number of observation stations there about what is happening is very thin, and those countries have to struggle to understand what those consequences might be and they need to know what is happening in the Himalayas. These are the kinds of information that is crucial. Are they working on it? Yes, they are, but with great difficulty, because the information is weak, and that is something which we can all work to support, but, as I said, you have got to use the information and you have got to face up to the reality that development is going to cost more.

  Q204  Mr Singh: Are there implications for DFID there then, in terms of how they refocus the emphasis of their work, and so on?

  Professor Lord Stern of Brentford: Yes. I do not speak for DFID, I have lots of friends who are in DFID and I stay close, but I do not have a comprehensive view of what they do, but I do know, through direct interaction, that they are very much seized of these issues. I know that they are investing, for example, on the information front in Africa and they are working strongly on this. In their White Paper of two years ago there is a chapter on climate change, so I think that DFID probably ahead of most, but we are all, as it were, playing catch-up here because of trying to understand just what these consequence are and likely to be and acting on the risks.

  Q205  Mr Singh: Do we have any idea of the current cost in terms of the impact of climate change.

  Professor Lord Stern of Brentford: Yes.

  Q206  Mr Singh: Have we any words to describe what the costs might be in the future and how do we plan for that? How do we get that into our planning?

  Professor Lord Stern of Brentford: For example, the World Development Report this year is on climate change, and I was last week with a team in the World Bank that is working on it, and this will, indeed, be the kind of issues where they try to move forward. What you will get is—. I gave you the Human Development Report figure. That is a couple of years old now. About 85 billion extra cost by 2015 as you run it forward. That is only a bet on 0.8 degrees centigrade, which is really small. It is big in terms of the reality of what it does to the world, but it is small in relation to what might happen to us. So these costs will be in their trillions, for sure, as you let it run forward 20 or 30 years, even if we are sensible with what we do. Of course there will be many more trillions if we do not act responsibly. So I think you are going to see these kinds of calculations come out, but I would focus particularly on the importance of understanding, country by country or region by region, what these consequences are like rather than just going, as it were, for aggregate numbers.

  Q207  Mr Singh: I think a DFID study of Kenya showed the costs at 5 % of GDP—

  Professor Lord Stern of Brentford: Already.

  Q208  Mr Singh: —already. Is that just for droughts and the famines?

  Professor Lord Stern of Brentford: I find the number in a plausible range, but, since I have not studied that DFID study, I should not comment on what it includes and what it does not include, but those kinds of number of damage now do not surprise me. Remember that we are talking about much bigger damages down the track.

  Q209  Chairman: Just on that point, to some extent you have acknowledged the updated figures such as the UNDP figure in your answer just now, but the problem is that virtually no money is actually being provided. Various reports suggest that even the UK has only delivered $300 million out of a pledge of 1.5 billion. So, if we are talking about anything up to 86 billion a year being required for adaptation and a few hundred million is all that is actually being delivered by the developed countries, does not the gap suggest that we are not really beginning to engage?

  Professor Lord Stern of Brentford: I do not think, as a community of people who are interested in development, we have factored this kind of challenge in to the extent that we should. I think increasingly people are becoming much more strongly aware of the issue and its implications for resources, and when you do that I think it becomes clear that we cannot within the United Nations Framework Convention on Climate Change generate the kind of resources that will be required for development in a more hostile climate. The conclusion I draw from that is that we have to think through its implications for development funding of the traditional ODA kind as well.

  Q210  Chairman: We are going to come to that.

  Professor Lord Stern of Brentford: We are going to have to face up to larger numbers.

  Q211  Chairman: I was going to say, large numbers are what the governments are talking about for bailing out banks, and so on. Is the urgency of the situation not such that actually the economic stimulus and climate change should be one and the same thing in the present circumstances? That seemed to be the implication of your opening analysis.

  Professor Lord Stern of Brentford: Yes, I have written a paper with colleagues at the Grantham Institute and the London School of Economics that the world needs a stimulus now of at least two trillion dollars to actually be spent in real terms in the next year or two, and within that at least 400 billion could go under a green hat as a green part of the stimulus. That is looking at it in aggregate terms and bottom up. So I do think that investment in new technologies, energy efficiency, bringing forward green infrastructure, and so on, should be a very big part of the stimulus. The adaptation story is a little different. What we are talking about here is short and medium term investment, particularly in the developing world, and I think we should not see that only as a matter of a stimulus package. I think it is still more important to see it in terms of our medium and long term commitments to development, because this problem stays with us. It is not a problem that is just here for the period of recession.

  Q212  Chairman: Do you have a figure for the UK in that?

  Professor Lord Stern of Brentford: For what?

  Q213  Chairman: You said 400 billion was a global figure.

  Professor Lord Stern of Brentford: I was talking about world stimulus, yes.

  Q214  Chairman: You have not got in your own mind a figure?

  Professor Lord Stern of Brentford: I am sure there will be more coming in the Budget, and let us look at it then. I am not sure, because I do not know what is in the Budget. I should say, but I would hope that there will be more coming on stimulus and the green stimulus, and I believe, from what the Government has said, that that is likely to be the case, but I left the Treasury two years ago, so I do not know what they would do, and when I was in the Treasury more than two years ago, if you had asked me just before the Budget, I would not have been able to tell you.

  Q215  Chairman: You are free now.

  Professor Lord Stern of Brentford: Yes. I have indicated where I think it should go.

  Q216  John Battle: I was always intrigued, and you made me think of it last time I heard you speaking—I cannot think who it was—of an old philosophy about unknown unknowns. I kind of think the only thing we know about recessions globally is that the poor always suffer the most, and what I found most encouraging about the present agenda, if you like, is that the sustainable development, the whole question of climate change and living within our limits is coming together with the agenda to root out poverty internationally. I find it quite encouraging if those agendas converge, but my biggest struggle on this committee in Britain, and elsewhere (and Britain has got a good track record) is every time we have a G8, as one is coming up, and Gleneagles, commitments are made and people say, "Oh, yes, we will make a contribution", but then the disbursements never quite keep with the promises and the pledges, and I worry again we will go through that process. I wonder if I can make a particular comment and ask you about Copenhagen, because already some people are writing off Copenhagen and saying we are further away in terms of targets than we thought we were, and I just wonder whether you could encourage me to say that there are real prospects for a new framework at Copenhagen. What are the chances of a new adaptation from it actually being agreed and the level of funding being pledged? Do you think we are further away from it or are we creeping nearer to it? I suspect we may be encouraged by the rhetoric, and I use that word positively, that the climate change agenda is tackling poverty, sorting out the world recession and the banks may all be on the agenda as items at the G8, but what can we sharpen up at Copenhagen and really start to get to grips with making this happen?

  Professor Lord Stern of Brentford: I agree with you. It is the poorest people in the world that are hit by weather and climate catastrophes, by inadequate development and by recessions, and we have to look at those three things together, and I have covered that, but it is terribly important. I share your encouragement. Actually, increasingly people are looking at those things together. I do want to say that I have sat in international institutions for ten years and looked at the UK from the outside, and DFID is, by some way, the best bilateral agency in the world and we all have ideas for helping it along, making it even better, but we should not lose track of that and we should not lose track of how far we have come on increasing development assistance in the UK. There is very strong cross-party support for the objectives of increasing to 0.7 % by 2013, which we were articulating in 2005. I think it is very important that we have got that cross-party support for that and I find it very encouraging, and I believe that the UK, under whatever government it is, will stick to that. So as we look for more, I think it is important to recognise that, whilst historically we have not been up there with countries like Denmark or the Netherlands, we are moving in a good direction. It is vital, for the reasons we were just discussing, that we keep going and raise our sights still further. I think that governments do have to be held to account for the commitments that they make, I think in this area governments also have to be held to account for commitments that their predecessors have made, because the relationship with a developing country and its national institutions are long term relationships and they cannot just be switched on and off, and I think it is important, as we think about what might come out of the G20, that we also think about institutional structures and political structures for monitoring commitments and delivery on commitments.

  Q217  John Battle: In Copenhagen do you think there will be the adaptation money there?

  Professor Lord Stern of Brentford: In answer to a previous question, I think I said that we do need adaptation funding to come out of Copenhagen, but that is environment ministers. They cannot make ODA promises, and I think that at the Prime Ministerial and Presidential level we have to make sure that this is part of the understanding around Copenhagen. If we go for it in Copenhagen, we have got a good chance. The most damaging part of Copenhagen would be people saying it is all too difficult; let us do it later. If we want to do it, we can do it as a world, and we are part of the UK and it is our job to support the UK, pushing for very strong agreement.

  Q218  John Battle: You do not want Copenhagen to replicate the problems with the trade rounds in Doha. You have got a positive track, I think.

  Professor Lord Stern of Brentford: It is very dangerous that that happens, because in a trade negotiation you can pick up five years later roughly where you were before; not with climate change.

  John Battle: Exactly.

  Q219  Richard Burden: It is on the point really. If tackling climate change and combating global poverty have really got to be two sides of the same coin and more investment needs to be put into all of that, should ODA in the future include adaptation—it is actually in front of ODA—so that you increase the whole thing and it is actually seen as one funding stream rather than separate, so it comes under one minister, and so on?

  Professor Lord Stern of Brentford: At one level it is unavoidable, because you cannot separate out. You cannot say this amount of this irrigation system I have been building is for climate change and this amount is for our battle against world poverty, as it might have been had the climate not been changing. It is very difficult to separate out those two kinds of things, and you can be disruptive and diversionary if you try too hard. So I think it is extremely important that the use of funding, whatever hat it sits under, is one which—. You can have an adaptation hat and you can have a standard ODA hat, but it has got to be used in a way makes it easy to integrate those things. You could, for example, have another window alongside the IDA window in the World Bank so that the people who were looking after those two windows were, roughly speaking, the same people, so that we could be sure that these things were being well blended. They have got to be blended with private investment, they have got to be blended with any of the guarantee instruments that any of the international institutions can use. It is extremely important that we do not lose the ability to bring that funding together in as easy a way as possible; so I am quite worried about excessive separation of streams. National income accounts are done in various kinds of ways, and I could give you an essay on how to see adaptation funding as a separate category in the national income accounts and I could give you another essay on how to see national income accounts putting adaptation and development funding in the same classification, and I would be worried if we got stuck on what is simply an accounting convention which can be done this way or can be done that way. It would be a very strange world if we let that have some kind of real policy significance. I fear that it might, but we should not let it.
