What to Expect at COP-27 in Sharm El Sheikh

The negotiators gathering for the 27th Conference of the Parties (COP-27) of the United Nations Framework Convention on Climate Change (UNFCCC) in Sharm El Sheikh, Egypt will try to tackle a significant number of important issues, with questions relating to increased ambition and financial transfers among those at the top of the agenda.  This is the focus of my podcast conversation with Ray Kopp, Senior Fellow at Resources for the Future (RFF), in the newest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.  You can listen to our full conversation here. 

Ray Kopp will be at COP-27 with the delegation of RFF.  I’ll be there, as well, leading our group from the Harvard Project on Climate Agreements.  At the end of this blog post, I provide a list of our activities at COP27.

Ray Kopp, who has been a leader in the design of domestic and international polices to combat climate change, explains in our conversation that the representatives gathering in Sharm El Sheikh will focus much of their attention on the implementation of the Paris Agreement, and therefore on the Nationally Determined Contributions (NDCs) – emissions reductions that individual countries have pledged under the Agreement. Under the provisions of the Paris Agreement, signatories are strongly encouraged to increase their levels of ambition and reduce emissions even further over time through the so-called “ratchet mechanism” that can bring the world closer to the goal of preventing temperature increases this century greater than 1.5 or 2 degrees Celsius, compared with pre-industrial temperatures.

In the podcast, Ray Kopp notes, “That mechanism will not be formally deployed until 2023. But I will say that there’s a synthesis report that has already come out from the UNFCCC Secretariat that gives us an idea of what those gaps look like with respect to hitting the targets, and they’re not encouraging.  We already know that there’s going to be a major gap. We’ve known that for quite some time. I haven’t seen a lot of countries step forward to increase their ambition in the recognition of that gap. So, the jury is out on how effective this mechanism is going to be.”

Another very important and contentious issue on the table at COP-27, Kopp explains, is that of monetary transfers from developed to developing countries to help them with their mitigation efforts and help pay for adaptation measures.  This is the well-known commitment from the developed countries to send $100 billion per year, starting in 2020, to the developing world.  That target level of annual finance has not yet been achieved.

“Right now, there is a bit of a lack of trust between the developing world and the developed world with respect to the deliverability of those funds going forward. And [for] developed countries, there is the problem that to be able to hit those particular targets you need a lot of private investment, not just government funds. And the private investment has been lacking considerably,” he remarks.

Debates around the so-called “loss-and-damage” issue will also play out in Sharm El Shiekh, Kopp notes, referring to the call by developing countries for the largest global emitters to pay for current and future climate change damages in the most vulnerable countries.

“This is … one of these issues that … becomes more salient and both sides become more vocal about it [at every COP], not surprisingly, because we are now seeing the impact of climate change, not only in the developing world, where it is severe and where people are at most risk, but here in the U.S. [as well],” Kopp argues. “There’s always going to be opportunities for the U.S. to provide aid to countries that are suffering these horrific damages associated with climate change. One of the issues is whether it is going to be taking the form of aid, which means it’s more of a voluntary contribution on the part of the U.S., or whether it’s compensation associated with some formal liability that the U.S. bears for these damages?”

Kopp says that negotiators could make headway on the ‘loss and damage’ issue if they take reasonable approaches.

“If both sides stick to their hard positions, where [in] the developed world it’s only about aid, and the developing world it’s about liability, and there’s no middle ground, then this will just be a confrontational experience.  Somewhere there’s got to be a middle ground … where we can think about insurance markets, [and] … other ways of financing the rebuilding after these particular [climate] episodes take place.”

When I ask Ray Kopp how he determines the success of failure of individual COPs, he responds by saying that each meeting is just one part of an ongoing process, and that in his opinion, the process is working.

“[Each COP] is an opportunity for the world to come together and talk about these things. The UNFCCC has put together an enormous amount of transparency in reporting. Sounds like things that are not all that exciting, but they’re fundamental to an understanding of where we are with respect to climate change and how to reduce emissions going forward,” he says.

Leading Academic Economist Offers Optimism about Climate Change Policy

Over the past three years, I’ve had the pleasure of engaging in podcast conversations with some truly outstanding scholars who have carried out important research in the realm of environment, energy, and resource economics, and recently was no exception, when my guest was Michael Greenstone, the Milton Friedman Distinguished Service Professor of Economics at the University of Chicago.  You can listen to our conversation in the latest episode of my podcast, “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”  Our full conversation is here.

In our conversation, Michael Greenstone talks about his graduate work in economics at Princeton, the path that took him to faculty positions at the University of Chicago, MIT, and then back to Chicago, as well as his time in government during the Obama administration at the Council of Economic Advisers.  In the process, Michael identifies both some high points and low points of his time in government, as well as some of the changes he has seen over the past twenty years in environmental economics scholarship.

When Michael reflects on his time serving as chief economist at the White House Council of Economic Advisers, he describes his work on regulatory policy, in particular trying to find a way to estimate in economic terms the benefits of reducing CO2 emissions.

“So, I had this idea, why shouldn’t the government have a coherent and uniform social cost of carbon? And I suggested it to [then Administrator of the White House Office of Information and Regulatory Affairs] Cass Sunstein at lunch one day, and we decided to set off on this journey to set a social cost of carbon for the U.S. government,” he remarks. “And we co-ran an inter-agency process and one thing led to another, and there was a U.S. government social cost of carbon at the end.”

Related to this, in recent years Michael helped launch and now co-leads the Climate Impact Lab at the University of Chicago, which is building a comprehensive body of research quantifying the impacts of climate change.

Interestingly, when I ask him to comment on the explosion of youth climate activism in recent years, although Michael voices some disappointment with young activists who have tried to turn climate change into a moral issue rather than an environmental, technological, and economic one, he notes that the energy and passion that young people have brought to the climate debate has been very effective in making others pay attention to it.

“These youth movements have been incredibly successful, in my view, in raising political consciousness in ways … that cold blooded cost benefit analysis somehow [doesn’t] seem to hit the mark. And I give them a lot of credit for that,” he says. “A second reaction is, I do not think that the right way to confront climate change is by treating it as a moral issue, or as an issue that is beyond economics. I think it’s a really interesting economic question that has all kinds of subtleties, but I do not think that the tools of cost benefit analysis and or economic analysis are inappropriate for climate change.”

Having worked extensively and intensively on climate change in both the scholarly and policy worlds, he voices considerable optimism about where we are now, and what the future is likely to bring.  He points to two trends he feels are most critical for building momentum in climate change policy debates. The first, he says, is that opportunities to leverage technology to reduce CO2 emissions are becoming more realistic as the costs of alternative energy sources continue to fall compared with the costs of fossil fuel sources of energy. The second, he says, is that people are beginning to experience in real time the impacts of climate change.

“I do think a real game changer has been that we can see the fingerprints of climate change now, in ways that we couldn’t 10 or 15 years ago,” he says. “I think the two things that we can see – the fingerprints and that it’s not as economically challenging a bar to jump over – have come together in a reinforcing way, and helped with the youth activism [by underscoring the fact that] we don’t have only infeasible responses.”

For this and much more, I hope you will listen to this 40th episode of the Environmental Insights series, with future episodes scheduled to drop each month.  You can find a transcript of our conversation at the website of the Harvard Environmental Economics Program.  Previous episodes have featured conversations with:

Thinking About and Measuring Another Greenhouse Gas – Methane

            In my podcast series of “conversations on policy and practice,” whenever we have talked about global climate change, the focus has been on one very important greenhouse gas – carbon dioxide (CO2), linked primarily with the combustion of fossil fuels.  And nearly all of my guests have been economists, political scientists, legal scholars, policy makers, or industry leaders.  Only one guest has come from the academic world of the natural sciences, and that was early in 2020, when David Keith was with me.  In my most recent podcast, I finally break the mold, by hosting Daniel Jacob, the Vasco McCoy Family Professor of Atmospheric Chemistry and Environmental Engineering at Harvard, a world leader in the development of powerful inverse methods to infer from satellite observations of atmospheric concentrations reliable estimates of emissions of another very important greenhouse gas – methane. 

My conversation with Professor Jacob is featured in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program. Our complete conversation is here.

In the podcast, Daniel Jacob explains how we should think about the relative importance of methane, compared with carbon dioxide (CO2), in regard to impacts on climate change.  He also provides insight about:  why there is great uncertainty regarding methane emissions; how technologies for detecting atmospheric concentrations of methane with satellites have been improving; and – importantly – how he and his research team use such satellite observations to infer spatially and temporally differentiated estimates of ground-based methane emissions.

Daniel explains that methane comes from a variety of sources: “There’s a natural source from wetlands. That’s about one third of the total source of methane right now. Two thirds are sources from human activity, and those sources include livestock, and in particular cattle, landfills, wastewater treatment plants, coal mines, oil and gas operations, and rice paddies.”

He goes on to explain that as a greenhouse gas, methane has impacts on climate similar to CO2, but there are very significant differences between the two.  First, methane is a vastly more potent greenhouse gas.  Its global warming potential is about 30 times that of CO2 over a 100-year period, and measured over a 20-year period that ratio grows to about 80 times the effect of a unit of CO2. The reason for the difference when measuring impacts over varying time scales is the significant difference in the atmospheric residence times of the two gases.

“Methane has a 10-year lifetime in the atmosphere because it gets oxidized.  CO2 is more complicated, but you can think of it as having about a 200-year lifetime,” Jacob explains. “What that means is that methane is responsible more for near term climate change, but also it means that acting on methane can give us a short-term response to climate. So, if we are trying to address climate change over the next decade or two, methane is a very powerful lever.”

From my perspective, Daniel Jacob’s work with satellite observations of methane is extremely important, because under the terms of the Paris Climate Agreement there is a need to accurately assess the national greenhouse gas (GHG) inventories that are reported by individual countries. Accurate measurements are also necessary under the terms of the new Global Methane Pledge, in which 119 countries have agreed to cut global emissions by 30 percent by 2030. But there has been tremendous uncertainty regarding the quantity and location of emissions.

As I noted above, Professor Jacob and his Harvard team use satellite observations of methane concentrations in specific locations at particular points in time, combined with additional information, to infer statistically, geographically and temporally differentiated emissions patterns.

“One of the things we can do uniquely from satellites is to look at recent changes in emissions, because the emission inventories that are coming out of individual countries are based on statistics that will typically be two or three years old,” Professor Jacob remarks. “But if we’re going to try to change the emissions rapidly, and to verify those changes in emissions, the only way that I can think of is to do it from satellites.”

Jacob recognizes that his satellite observations research could have substantive impacts on climate policy in the years ahead:  “What I would like to see is that we can contribute to continuous monitoring of emissions, to be able to detect changes in emissions, particularly if those are correctable, and point to the need for action. Say for example, if you have a flare that goes off, we should be able to see it from space, and then be able to take action on that.”

You can also see a brief video of Daniel Jacob talking about his research.

For all this and much more, I hope you will listen to my compete conversation with Daniel Jacob, which is the 39th episode in the Environmental Insights series, with future episodes scheduled to drop each month.  You can find a transcript of our conversation at the website of the Harvard Environmental Economics Program.  Previous episodes have featured conversations with:
