Economics Can Still Help Solve the Climate Crisis

PolicyCast

Critics called last month's UN Climate Summit a disaster, but environmental economist and Harvard Kennedy School Professor Robert Stavins says global climate negotiators actually laid the groundwork for meaningful results in the future.

Thoko Moyo: Hello and welcome to the Harvard Kennedy School PolicyCast. I'm your host, Thoko Moyo. Today we're joined by Harvard Kennedy School Professor Robert Stavins. Professor Stavins is the Director of the Harvard Environmental Economics Program and the Harvard Project on Climate Agreements. He's also just returned from Madrid, where he was participating in the 12-day UN Climate Change Conference, or COP25. So you're just back from the UN climate talks, COP25 in Madrid. The general consensus when you're reading the newspapers are that it didn't really achieve what people were hoping. Would you agree with that?

Robert Stavins: Well, there's what people were hoping and what were reasonable expectations. I would say in general the COP was moderately successful, in that it sort of advances the ball. It passes on the ball till next year. I think what people were disappointed with—that you saw reflected in the popular press—was that there was not a statement, an aspirational statement, of countries talking about new targets that they would come up with next year, not this year, but next year. And that's what a lot of activist groups, and particularly this new wave of youth activists who are obviously very important, were looking for. But I don't actually consider those kind of aspirational statements with no meat to be very important in the first place.

Thoko Moyo: Okay, great. Okay, so let's come back to that. But I think because we might have some people listening who are not experts, who probably maybe need a reminder, things like COP, what is COP? And then let's also maybe just get it out the way, because it's going to come up in our conversation, the Paris Accord, what is that? And I know just in September we had the huge UN Climate Action Summit, so what's that? What are those three things and how do they fit together?

Robert Stavins: It starts in 1992 with the United Nations Framework Convention on Climate Change, which grew out of the Earth Summit in that year in Rio de Janeiro. The signatories to that are the parties to that agreement, the UNFCCC, the United Nations Framework Convention on Climate Change. They met for the first time in 1995, so that was the first conference of the parties. That was COP1. This year was the 25th conference of the parties. That was COP25.

Thoko Moyo: Okay. And so that then grew into or at least led to, in 2016, to the Paris Accord, the Agreement. What was that and why is it such a big deal?

Robert Stavins: Again, I'll put it in a historical context. I think it might be helpful. That is, in 1997 at COP3 in Kyoto, Japan, countries agreed to the Kyoto Protocol, which was the first significant international agreement on climate change. That expires in 2020, so in 2016 in Paris, the conference of the parties established a new agreement that would succeed the Kyoto Protocol beginning in 2020. That's what the Paris Agreement is.

Thoko Moyo: And the Kyoto Protocol, if I remember correctly, had targets and sounded like it had some way of enforcing, whereas the Paris Agreement seemed to step back a little bit and make it more the onus of the countries to determine what their reductions would be or not. Is that right, and why did they move in that direction as opposed to more top down?

Robert Stavins: That's right. The Kyoto Protocol was very much a top-down approach. A very small number of countries actually were engaged in taking on targets. It was the set of countries that were essentially the industrialized countries of the world at the time, plus what were then the emerging market economies of Central and Eastern Europe. Those countries, which were listed in an appendix, Annex 1 of the Kyoto Protocol, they took on targets and timetables, but those targets and timetables that they took on, those specific numbers, were negotiated among the set of countries. So I negotiated what your target would be, and you negotiated what my target would be. That's the top-down nature of the approach. Everyone was involved.

The scope was very narrow, so that currently in the second commitment period of the Kyoto Protocol, approximately 14% of global emissions are associated with complying countries. That's European Union plus New Zealand. The United States never ratified the Kyoto Protocol. Russia dropped out, Japan dropped out, Canada dropped out, and Australia dropped out. So it's a very narrow scope, but it was of a top-down structure.The countries of the world, particularly the United States and China, who played a leadership role leading up to Paris, they realized that that approach was never going to achieve much in terms of meaningful reductions, namely because emissions are either declining or relatively flat in the industrialized countries.

The place where the emissions growth is so great is the large emerging economies, China, India, Brazil, Korea, South Africa, Mexico, and Indonesia. And so those countries had to be brought inside. It was clear that it would not be possible to bring them inside with the top-down approach, that rather each country would have to say what it felt it could do given its national circumstances as well as its domestic politics. So the approach that's in the Paris Agreement is this bottom-up approach, in the sense of each country says what they're going to do. There are parts that are top-down that are binding under international law, but those are simply parts that say that every five years each of the countries has to come up with a new target, not what the targets are.

Thoko Moyo: But how does it work? I mean, this is a huge emergency, affects everyone, and it's a bit of an honor system. You say what you can and you try and keep to that, but does it actually work? I mean, do the countries set ambitious targets, and if there's no way of enforcing it, how do you even know they're doing what they said they'd do?

Robert Stavins: Well, there's an interesting trade-off, that the very element of the Paris Climate Agreement that caused it to have the broad scope of participation it does, namely compared to that 14% under Kyoto, we now have 97% of global emissions associated with signatory countries. If the United States does drop out, as it has said it would approximately a year from now, that 97% drops to 85%. Either way, it's very impressive scope, but that same element that caused the scope to be very broad and inclusive ...

Thoko Moyo: Which is important.

Robert Stavins: ... which is very important, it also then brings about the reality that the ambition of the individual commitments or statements is not going to be very great, because it's a global commons problem. Any country that takes action incurs the cost of taking action, but the benefits are spread globally, meaning that for any individual country, the direct benefits it receives are going to be less than the direct costs that it incurs. So it's a fundamental consequence of the structure of the agreement, of this trade-off between adequate scope, but perhaps not adequate initial ambition.

Thoko Moyo: I guess an obvious question, then, is why would, I mean apart from the politics, but there might be another reason, why would the US pull out of an accord that doesn't tell it what it needs to set as targets, and certainly there's no enforcing? Why not just reduce the scale of your ambitions and do what you can? Why is it so important to withdraw from the accord, or is it just politics?

Robert Stavins: Well, that's a very good question, and I guess my flippant answer would be you should ask the resident of the White House, not me, but back when, you may recall that former Secretary General of the United Nations Ban Ki-moon was resident at the Harvard Kennedy School as a visiting fellow and maintains an affiliation. When he was here about two months before the White House issued its decision, before the president spoke in the Rose Garden with his decision to pull out of the Paris Agreement, Ban Ki-moon and I wrote an op-ed that was in the Boston Globe. And we posed the same question, saying that what the United States could do would be to stay in the Paris Agreement so that you have a voice in deciding what's going on, but to change what is called its nationally determined contribution, this bottom-up pledge. It could even make that to be equivalent to business as usual, so we didn't have to do anything. It could have set it at anything.

That would have been an approach which would have been consistent in terms of what people in the administration were saying, but what it would not have accomplished is what, in my opinion, and I'm bi-partisan, with what the president wanted to accomplish, which was the announcement. The important thing was not what we did, but what he was able to announce, in terms of his political base. And he had the positive spin on that as he was living up to a campaign pledge. He said over and over again, is that he would pull us out of the Paris Agreement, and that was the decision that was made. What the president may not have recognized, although I would hope that White House staff recognized, was that when he announced that in June of 2017, what he was actually announcing was an intention to remove us from the Paris Agreement approximately three and a half years later, because that was the soonest that it could actually become effective, which is approximately a year from now.

Thoko Moyo: And so how much of that came up in the talks, in the COP25 talks? Because we saw some coverage of the former mayor of New York, Michael Bloomberg, saying that a lot of cities in the US are committed to the Paris Accord and they'll stay in it if they could. We didn't really hear much about the official US position. What was said?

Robert Stavins: Well, the US did not have political level appointees present, so it is the State Department officials who have been working on these issues for 20 or 30 years. It's what sometimes is derogatorily referred to as the deep state, although being at the Harvard Kennedy School, where we're producing people that go into that world, whether it's the State Department or the Department of Agriculture, we think it's not the deep state. It's rather an extremely important professional class, and it will be wonderful if the US had it of the quality that France and so many other countries do. Those individuals have been consistent. Some have left, but they're still there.

And in fact, one of the things I'll tell you that I was struck by, certainly last year when we were at the talks, which were in Katowice in Poland just one year ago, is that when we would sit down in the room to talk with a negotiating team from some other country in the world at their request, because they're interested in the research we're doing and looking for help with that, they would say, "Well, Stavins, you're from Harvard, right?" "Yes." "That's in the United States. Before we talk about your research and what you're doing, we just wanted to say something to you we don't understand. You know, your president says that climate change isn't real, and he's pulling out of the Paris Agreement, but your delegation is here and they're working very constructively." And that's something I never repeated to the press, lest it be read by some congressional staffer, and it'd get back to the White House. But the US delegation has actually continued at that level to be quite constructive. They've continued in particular, jointly with China, to run what's called the transparency, which is the monitoring, reporting, and verification aspects of the climate talks.

Thoko Moyo: And is the US unique in having a sort of high profile, it seems high profile, debate about whether climate change actually exists, or are there other countries as well that have that sort of debate in a way that's quite prominent in the politics?

Robert Stavins: The United States is close to unique. What is true is that Australia, as it's gone from governments back and forth from right to left, when governments have been in from the right, conservative governments, they have been very resistant to any action on climate change, and the Australians played a role in that in these talks just now. What's even more striking is certainly Brazil, President Bolsonaro, who is a right wing populist climate skeptic, so not unlike our own president. They have also played that kind of role. And then certainly the Gulf oil states, in particular Saudi Arabia, have been very vocal in the climate talks, which is perhaps understandable, because for them it's not just increasing their costs, it's perhaps sending their economy back to what it was 75 or 100 years ago if there was no demand for fossil fuels.

Thoko Moyo: Okay. The other thing that we were going to get out the way is the UN Climate Action Summit that was in September, and that saw one of the largest youth-led protests in history. How is that different from COP25? What was that?

Robert Stavins: Those climate summits in September is something that was started by the previous Secretary General, Ban Ki-moon, because he had decided to make climate change an important issue for himself, and so he saw a September summit as an opportunity, a cheerleading session really, to bring countries together into the General Assembly, let heads of state give speeches at lots of different sessions in meetings, before three months later when the annual conference of the parties would take place. And they have continued since then. And I would say the role that it has played is precisely what was intended. It's a cheerleading session, by which I don't mean to denigrate it, but just to take it at what it is. There's no legal authority there. It's not part of the United Nations Framework Convention on Climate Change negotiations.

Thoko Moyo: But it gets attention focused on it.

Robert Stavins: It draws attention, and it certainly does. It also ties up the traffic in Manhattan, as New Yorkers will tell you, for a week.

Thoko Moyo: Okay, so let's actually go to the meeting, COP25 in Madrid. This year's tagline was "Time for Action," and it does come at a time when there's been more and more scientific evidence to show that there are devastating effects of climate change on land, oceans, and societies. We started off by saying that you thought it was a moderate success. Let's talk a little bit about the sort of hopes, expectations, or goals of the meeting going in.

Robert Stavins: They were twofold. I mean, there were the popular press and from the activists, expectations and hopes, and those were for statements in what is called the decision, which just means the statement that comes out at the end of the COP with no legal force, it's just a statement that comes out at the end, the decision, that they wanted a statement that countries were committed to coming up with much more ambitious targets a year from now in 2020 when the next set of targets will be submitted at the next COP. So that was for them, and that definitively did not happen.

And that's why those individuals, and I think much of the press, because that's a pretty obvious sort of thing to talk about, is what are the targets, what's the aspiration, have characterized it as a terrible failure. I know The New York Times did this morning. But for those people, both the negotiators and for those of us on the outside in NGOs and in universities who are very engaged in the process and in research, what we were looking at much more was the actual text of the Paris Agreement, what wasn't being completed and what needed to be completed, just in order to achieve the targets that they already have pledged, let alone thinking about the next set of targets.

Thoko Moyo: And what were those things?

Robert Stavins: And that was something very specific in particular, and it ties in with the notion of international carbon markets. There's one portion of the Paris Agreement, which is Article 6, or even to be more picky, Article 6.2, that provides for countries to cooperate with one another so that one country can help another country to accomplish something. And then the country that does the helping can take credit for that against its pledge that it's made.

Thoko Moyo: Okay, so said another way, if you are performing poorly on your targets, you could set up a deal with a country that's over-performing on their targets and somehow get... I mean, how? How does it work?

Robert Stavins: It wouldn't necessarily be a country who is performing poorly. They might be performing perfectly, but nevertheless that they could finance what's taking place in another country. So it's a matter of finance. In fact, it's a means of foreign direct investment. It just means that the incremental costs, what economists call the marginal costs, of reducing CO2 emissions vary tremendously across different countries, and that's because the modern economies were already very energy efficient, and so there isn't a lot of low-hanging fruit. But if you go to other parts of the world, there is low-hanging fruit. There are a lot that can be done at relatively low cost.

So that means if you're in one of these countries where it's very costly, you could finance things being done in one of those other countries. That's to everyone's benefit, if it's voluntary on both sides, and it's a means of foreign direct investment into those countries, which of course they're very happy about. The big issue there, though, is to make sure that both countries don't take credit for that same emissions reduction, that there isn't double counting. That's where the Paris Agreement comes in. That's what article 6.2 is potentially about, are accounting measures to prevent double counting. That was not completed. That's the one part of the Paris Agreement, what's called the Rule Book, which is the text of the rules, that was not completed last year in Katowice. It was punted to this year. So for the cognoscenti, for those of us who are really involved a lot in the Paris Agreement and in the negotiations, the goal was to complete Article 6. That's what it was about.

Thoko Moyo: And was it completed?

Robert Stavins: And Article 6 was not completed, but I'm going to give you an important caveat, it was not completed because Brazil and Australia, Saudi Arabia in particular, wanted some aspects in there that would have introduced loopholes that would have allowed double counting. And so what I take as the good news, and that's why I say a qualified success, is that rather than producing what would have been a bad deal, they produced no deal. And I'm very serious about that.

We did research here at Harvard years ago with colleagues at Tufts University and MIT, in which we said what needed to be in the Paris Agreement on this issue of sharing responsibility, bringing down costs. And we said the first important thing is that they not put in the following kind of items, which would make everything worse, and that didn't happen. So it's in that sense that I think it's a qualified success, that even though there's no deal, there's still a possibility for it at the next meeting.

Thoko Moyo: At the next meeting. So you think that something can happen in the next 12 months before Glasgow to get to a point where you have the sort of accounting rules or standards that could get Article 6 done?

Robert Stavins: That's exactly right. I think that that can happen. I wouldn't say that I think it will happen, because there is political opposition to it happening.

Thoko Moyo: Let's talk a little bit about the voices at these talks. The most obvious sort of divide, as it were, would be between developed and developing nations. How does that play out? I mean, who gets to talk here and and who gets listened to?

Robert Stavins: That's an exceptionally important point, as it is in the United Nations in general. As an economist, whereas normally most of the analysis we do, whether it's teaching in the classroom or it's research on the outside or it's conversations with the government, are focused on efficiency issues. But when you get into climate change, the international aspects, the aspects of distributional equity are extremely important. Going all the way back to the beginning, 1992 Brazil Summit, there's a very important principle in the overarching document, the United Nations Framework Convention on Climate Change, which is, although it's a global commons problem, we're all in it together, nevertheless, there are common, but there are differentiated responsibilities.

Different countries have contributed different amounts to the accumulated stock. United States is number one, China's second. And there are different capabilities, different wealth. That principle is exceptionally important, and everyone in the negotiations recognizes that. Having said that, as you said, that there has been in the past a polarization between the industrialized countries and the developing countries, and that was codified in the Kyoto Protocol, because only the industrialized countries had responsibilities.

Under Paris, it's much more of an even playing field, although obviously some countries, particularly the European Union, take on much more aggressive targets than do poorer countries. Certainly, countries in Sub- Saharan Africa, from my point of view, need not do anything, I mean, their contributions are small and they're mired in terrible poverty. So that differentiation remains, but there are lots of other constituencies at play. A very important one are the Small Island States, because for most countries in the world, ranging from the United States to the European Union to even the Gulf oil states, when we talk about addressing climate change, we're talking about an increase in cost to our economy or a reduction in productivity. For the small island states, climate change is existential, so it's at a whole nother level of concern. So their voice is very important, and although they are very small in terms of population, although they are very small in terms of their share of global gross domestic product, they're actually very vocal and very effective, I'd say, in the talks. Remember, one last point is that under the rules of the United Nations, voices are all one country, one vote. The United States has the same vote as the smallest country in the world.

Thoko Moyo: Okay. Okay. So just one more question, just looking at the actual meeting. Another thing that we're getting used to is seeing the protests and the demonstrators, and I know in Madrid one session you had protestors actually storm the session. We read a lot about the protest out on the streets. Is that actually having an impact? Is that sort of pressure having an impact on the deliberations and the progress that could be made?

Robert Stavins: Well, I think it certainly provides support, for example, for the small island states, the countries that wanted the most aggressive pledges to be made, because they feel tremendous support there. I don't think it had any effect on the pace of the negotiations themselves, except that they were disrupted for a few hours that one afternoon. Other than that, I don't think it has any particular influence. I'm not making a judgment with that. Maybe it should, maybe it shouldn't, but I don't think it does.

Thoko Moyo: Okay. We've talked a little bit about, you're an environmental economist. Why is the economic perspective important in environmental issues? I mean, what are some of the things that you think about, and necessarily, what's in your research?

Robert Stavins: Well, what I'd start by saying is that the causes of environmental problems, whether it's economics or it's local hazardous waste, the causes of environmental problems are essentially economic. It's a result of the fact that there are unintentional negative aspects, consequences, factors that are the result of fundamentally meritorious activity by private firms making the products or the services that you and I want to buy. And sometimes the result of consumers when they're using those products. They are external to the decision-making, which is why economists refer to environmental pollution as an externality.

And there are also then consequences of environmental pollution that have economic dimensions. So surely, if the causes of environmental pollution are fundamentally economic, which they are, and if the consequences of environmental pollution have important economic dimensions, then that would suggest that an economic perspective can be helpful for understanding those problems fully.

But you know, we're sitting here at the Harvard Kennedy School, not at the Department of Economics in the Faculty of Arts and Sciences, so it's not understanding just for understanding's sake, it's understanding so that we can make a difference. And the way that this understanding can make a difference is to identify public policies that are effective. And by effective, I mean they reduce pollutant emissions, they don't simply demonize the bad guys, that they are economically sensible, by which I mean they're cost effective, that we don't shoot ourselves in the foot and spend more than we have to. After all, we don't only care about the environment, we care about the cost of education, healthcare, food, fuel, and a thousand other things. And that perhaps they're more likely to be politically pragmatic. I think this economic perspective, although it's not the only legitimate perspective, surely, can be helpful in those regards.

Thoko Moyo: You mentioned the private sector in that, actually, and we haven't talked about that. What role does the private sector have in the solutions in climate change, and what sort of actions are required of, and what sort of actions are private sector taking?

Robert Stavins: Well, the private sector plays an extremely important role, because that's where the emissions for the most part come from, either actually from private industry, from manufacturing, electricity generation, or from products that they produce, such as motor vehicles. So their role is exceptionally important, and I've long had the view that only working through the market can much be accomplished. You know, that's why, if I may say, back in 1988 when I first joined the faculty at the Kennedy School, a previous dean, Graham Allison, that he and I launched a project which was titled Harnessing Market Forces To Protect the Environment with two members of the US Senate, a bi-partisan pair of senators, something you couldn't conceive of today, because it's so important to work through the market.

Robert Stavins: And private industry in my view is aware of that. So there's a lot of support actually from private industry for, for example, the Paris Agreement. The lobbying of the White House on the Paris Agreement, when there was about a six-month period in which it wasn't clear what the president was going to decide about pulling out of Paris or not, private industry, with one exception, that's the coal industry, was lobbying to stay in the Paris Agreement. And that includes the oil and gas industry.

Thoko Moyo: Interesting. And so what sort of promising approaches have you seen, the things that you're particularly excited about in the markets that you think could have a real impact on the goals for climate change?

Robert Stavins: Well, I think the best thing, frankly, that private industry can do is to press for public policies in this realm, so it really takes me back to government. I don't think it's ever going to be dealt with sufficiently through voluntary actions by private industry, because again, it's an externality. It's not in the interest of their bottom line. They have fiduciary responsibilities to shareholders, and it's taking money from shareholders to spend more than your competition is. So I think the best thing they can do is what to some degree they have been doing, and that's to press for more aggressive public policies, whether it's in the international domain or more importantly in the domestic national policies. And then when those public policies are put in place, not to fight them, but to comply.

And actually, the largest corporations do that, partly because they're more equipped to take on the costs, but it's particular sectors that would be really hard pressed that find it most difficult. It's interesting, something that's, I don't know if it's even recognized in the popular press, but that if you look at the climate legislation during the Obama administration, which was called the Waxman-Markey Bill, this was going to include a cap and trade system and lots of other policies to address climate change, that at that time there was a private industry consortium supporting the legislation, and that included a lot of large corporations. But there's something that all of those corporations had in common. They all produced energy-consuming durable goods. So in there leading it was General Electric. The automobile companies were in there, Boeing was in there, because a climate policy means an increase in energy prices. When energy prices go up, that's good for those companies, because it renders prematurely obsolete the current stock of energy-consuming equipment, because suddenly energy is more expensive. I mean, the reason why United Airlines buys a new airplane is not because they want the one with blue lights in the ceiling instead of white lights, it's because it's more efficient. And it's more efficient, actually, not because of more efficient engines, it's more efficient because the aircraft is lighter. They use composite materials rather than metals to build the aircraft.

Thoko Moyo: So there's a business case for it.

Robert Stavins: There's a business case, so those are the ones that were supportive. On the other hand, you didn't see United Airlines or Lufthansa lobbying for that, because for them it's an increase in cost. The price of jet fuel goes up a little bit, that's the difference between profit and loss year after year after year for commercial airlines. So a lot of industries are supportive of climate policy because of the fact that it'll help their bottom line. There are other ones that are not affected much one way or the other, but they're still supportive, for example, of staying in the Paris Agreement or of some climate policies, because what they want is certainty. What they really hate is the uncertainty of not knowing what's the price on carbon going to be 10 years from now? It's so hard to make investment decisions on that basis.

Thoko Moyo: We don't have a lot of time left, but I do have two more questions. I want to hear a little bit about your research, what it is that you are working on and sort of key findings and any sort of policy recommendations that come out of it. And then I want to look ahead to next year at Glasgow. I mean, what are the big expectations or hopes for that meeting, and what's your sense in the next 12 months about that?

Robert Stavins: There have been two major threads of my research over, we'll say, the past year, year and a half or so and going forward. One we've already talked about, it ties in with international cooperation and how that connects with Article 6 of the Paris Agreement, so I won't say more about that. The other thread has been looking at and comparing the two major carbon pricing policy instruments, the two ways of working through the market to address climate change. One is with attacks on the carbon content of fossil fuels, coal, petroleum, and natural gas. That's a carbon tax. The other is with a carbon or CO2 cap and trade system.

These instruments are hotly debated. Economists around the world and most policy analysts would say yes, we need to have carbon pricing in a modern economy. We won't be able to achieve sufficient emission reductions in any other way. Why is that? Because when we're talking about CO2 emissions in a country such as the United States, for example, we're not just talking about 1,500 sources, as we were for sulfur dioxide with acid rain. We're talking about every electricity producer that uses fossil fuels, every manufacturer, every commercial facility, every residence, every motor vehicle, every backyard barbecue grill and lawn mower.

Robert Stavins: It is inconceivable that those could be regulated with conventional standards, technology and performance standards. The only way to affect all of those is with the dissemination through the market of relative prices. So there's this agreement that carbon pricing is necessary, maybe not sufficient, for the task, but necessary. Where the disagreement has come in is carbon tax versus cap and trade.

I recently did research for the National Bureau of Economic Research, in which I think I wrote what is a relatively exhaustive and probably the most comprehensive study that's ever been done of comparing the two instruments. And my conclusion, which surprised even me, was that actually the choice between the two, that dichotomous choice, is vastly less important than the design of either one, that actually there's a policy continuum from a pure carbon tax to a pure cap and trade, from a pure price-based mechanism to a pure quantity-based mechanism, if both work through the market. And then it's various points along this spectrum are determined by the design.

Thoko Moyo: So either-or or both together, well-designed.

Robert Stavins: Yeah, either one well designed, either one well designed. And so then the question comes up is, if it is well designed, gee, it's still not happening in the United States, and that's surely because of political factors. So what I'm working on now with a Harvard Kennedy School PhD student in public policy, Dan Stewart, and a Harvard PhD recipient, now a professor at Duke University, William Pizer, is looking at the politics of this, really, and analyzing how these different instruments, and some others that are of great interest in the Congress, compare when we really take into account the political feasibility of different approaches going forward. And that's research that we're just beginning at this moment.

Thoko Moyo: Okay. So to end off, we've talked about COP25 and how that went. Another one coming up next year in Glasgow. What's the sort of focus there, and what's your sense about what should be focused on between now and next year and what the meeting will center on?

Robert Stavins: My hope would be that Article 6, this last part of the Paris Agreement in which the Rule Book has not been completed, that this can be completed in ways which are simple and, if I could say so, relatively pure. This is a case in which less is more. It will be much better to have something which is five sentences long, which simply validates global carbon markets and doesn't get in the way, than to have detailed rules that go on for four pages, but of those four pages, there are two paragraphs that cause problems.

Thoko Moyo: I can't imagine five sentences in a UN document, though.

Robert Stavins: Well, that's the challenge. That's the challenge. But you know, the Paris Agreement is only 13 pages long. It's not a long document. So there is reason to hold out hope for something which is brief and simple. Last, if you ask me what my expectations are, I think that the demonstrations will be even greater, that youth activism in this realm is surely on the rise. I'm from an era in which there was youth activism I participated in on the Vietnam War. So I applaud the youth activists. I don't want to sound like my father did to me at that time.

Thoko Moyo: But it's real. I mean, the young people are the ones who are really, truly going to feel the biggest effects of what's happening today. It makes sense that they are focused on it. It's literally their lives at stakes.

Robert Stavins: Yes. No, and continue the analogy with Vietnam, it was because for young people, we were the ones that were going to go off and fight. It wasn't going to be the 60-year-olds who are going to go off and fight. But you're right, there is a reason why youth have the attitude they have, and I applaud them for it.

Thoko Moyo: Terrific. Thank you so much. This is great.

Robert Stavins: My pleasure.

Thoko Moyo: Thanks for listening. Please join us for our next episode, when we'll talk with Harvard Kennedy School Professor Archon Fung about civic engagement and responsibility and how to ensure that in 2020, American democracy isn't a spectator sport.
