Astrid Schomaker is the new executive secretary of the Convention on Biological Diversity (CBD).
Schomaker, who is German, was previously the director for green diplomacy and multilateralism with the European Commission.
She took over as the UN’s biodiversity chief in July this year, just months out from the major UN biodiversity summit, COP16, which will take place in Cali, Colombia from 21 October to 1 November.
Carbon Brief spoke to Schomaker ahead of the Cali talks to discuss progress on nature targets, key negotiation sticking points and boosting the profile of biodiversity COPs.
- On COP16: “We had an ambitious framework put in place just two years ago and now we need to look at whether this has actually been the game-changer that people think it has been.”
- On low national biodiversity plan submissions: “The start was never going to be fast. I think the important thing we’re looking at is the work is underway.”
- On combining the efforts of the biodiversity, climate and desertification COPs: “What one would hope is that these three COPs now can actually give a push to countries committing to bringing this together.”
- On biodiversity finance: “There is movement across the world and, therefore, I think the outlook is broadly positive. Is it enough? No. Does it have to be scaled up? Absolutely.”
- On Colombia as host: “They’ve made a lot of efforts to make this COP a success. And, in Susana Muhamad, we have a very knowledgeable and a very charismatic and very dedicated COP host.”
- On security: “We are reassured that good security arrangements are in place, both in the city of Cali and for the COP specifically as well.”
- On world leaders at COP16: “The nature crisis has to be understood as being at the same level of seriousness as the climate crisis and, therefore, also requiring the same level of political attention.”
- On the US and the CBD: “Whatever the outcome of the next elections will be, ratification has not been a subject that was actively discussed in the US recently.”
- On Indigenous input: “This is actually a big issue on our agenda and also one that’s very important for Colombia.”
- On COP17 hosts: “We have two offers on the table at the moment – Azerbaijan and Armenia.”
- On genetic resources: “We think this could actually generate considerable finance streams for biodiversity-rich countries and, therefore, it’s important that we move ahead with it and put in place a mechanism that is workable.”
Carbon Brief: We are less than two weeks out from the start of COP16. There are thousands of people all around the world getting ready to head to Cali in Colombia to discuss implementation of the 2030 targets, sharing of genetic resources, biodiversity finance, all of this range of other issues. I assume this is going to be a huge moment for you in your role, especially as you only took it up in July. How are you feeling ahead of the talks? Are you excited, intimidated?
Astrid Schomaker: Well, mostly excited, and quite optimistic. I think for us in the convention, it’s a big moment. We had an ambitious framework put in place just two years ago [at COP15] and now we need to look at whether this has actually been the game-changer that people think it has been. And that, of course, means we need to look [to see if] these commitments[are being] actually implemented, and COP will give us a good chance.
For us, it’s important to see also the huge mobilisation. We have the biggest COP ever. We have the biggest green zone. We have more media, more business, more stakeholders [and] more delegates than we ever had before.
So we think that, in a way, when people say it’s nature’s moment, now really is nature’s moment. People [have] come to realise that we need to have a different relationship with nature. Take better care of nature. Look at nature together with climate change and see that we cannot solve the climate crisis without looking at the nature crisis. So it’s mostly a moment of anticipation and excitement.
CB: Broadly speaking, what are the main outcomes you want to see from COP16?
AS: The first thing is to have a look at how implementation is actually progressing. We said at COP15 [that] countries should prioritise national targets. So far, we have 79 countries that have put national targets in place. We expect more by COP, and maybe also some to be announced at COP. So that’s quite a good number.
What is important in particular, and then compared to what happened previously under the Aichi process, is that most of these national targets actually reflect the global targets, so they make direct linkages. And also, it’s not just a kind of pick-and-choose approach. But it’s in the majority, actually, [that] all targets of the GBF [Kunming-Montreal Global Biodiversity Framework] are reflected in the national targets. Or at least, I think more than 75% of those targets are reflected in national targets. So that’s a good number.
On the national biodiversity strategies and action plans [NBSAPs], the number does not look quite so good. We are at 20 so far. Again, we know lots of countries are now finalising their plans, stepping up action. One may think it’s a low number – and certainly this has been pointed out by some NGOs.
On the other hand, we have been holding workshops around the world, and we’ve seen that countries literally around the world are working on these action plans and, in a way, they take longer because countries have taken to heart this call for a whole of government approach.
So it’s not an environment ministry which sits somewhere, drafts a plan, adopts it and submits it. It’s really an exercise where governments come together across the board, where stakeholders are being consulted and then often also where these action plans are then adopted at a higher political level.
So at the COP, we will have an opportunity to look at these first action plans and targets. We have a pre-meeting, our subsidiary body on implementation, that’s basically entirely dedicated to looking at these plans and then to discussing where are the bottlenecks, where are the difficulties, where are the good practices that can be shared.
CB: Back on the NBSAPs then. As you say, there has been criticism from NGOs like WWF and other places about this figure of 20-odd countries at the moment out of 196 – about 10% – that have submitted these national biodiversity plans. That seems like a very low number, especially if you think about the climate COP. If only that number of nationally determined contributions were submitted, there would be uproar, let’s say. Were you surprised by this low level of submissions so far? And also, are you worried that it could indicate that countries are not taking global nature pledges seriously and even that they could not be met by 2030 as a result?
AS: I think if we look at the deadline, it was very short. I mean, COP15 took place in December 2022, so it’s less than two years. Many countries had to put new processes in place, had to get funding. So I mean, the start was never going to be fast. I think the important thing we’re looking at is the work is underway. And there, I’m confident to say, it’s literally underway around the world in countries. So whether the deadline itself is met on the dot is not what I think we’re really looking at. We’re looking at how far countries advance, how are they talking to their stakeholders, how are they managing to also have these new processes that would involve better reflecting traditional knowledge, for example, involving Indigenous people, where that’s relevant.
Bringing the business sector on board was, as you know, in the Global Biodiversity Framework. There are also targets for business. So all of that takes time. Since we’ve done these workshops, and we understand that countries are working on that, I think our assessment is globally positive. This is not to say that more than 20 would [not] have been better, but I think the important thing is to look that progress is there. And I’m confident that by the end of the year, the number will be significantly higher.
CB: Do you have any estimate of what that number could be?
AS: No, I don’t.
CB: Will CBD analysis on the plans and targets put forward by countries still be done this year, in light of the low number of NBSAP submissions?
AS: The full analysis is basically for COP17. That’s when we have our stocktake. So what we’ve done now, and you can see that in the documents that have been published, we’ve been just looking basically at how the targets are reflected. We haven’t got an in-depth analysis and also, at this point in time, countries were asked to submit their targets. They were not asked to report to us how they are implementing those targets. So we’re basically still at this level of really demonstrating that the commitments were taken seriously and looking at how they’re being translated into targets, but we’re not at the stage of analysing implementation.
CB: Do you think that the NBSAP issue indicates that there needs to be a wider, more UN COP-level reform? Susana Muhamad this week was talking about unifying these targets that are put forward to the climate change, biodiversity and desertification COPs. What is your take on that opinion?
AS: I don’t think that’s a call for UN reform or necessarily unifying targets. I think what everybody is looking at is, first of all, the opportunity that we have this year with these three Rio Conventions having their COPs in rapid succession. And, of course, with basically planning processes going on under land degradation neutrality for desertification, and then national adaptation plans and the enhancement of the NDCs [nationally determined contributions] under the climate convention, then our NBSAPs.
What we have all been saying – specifically two weeks ago in New York when the Rio Trio initiative was launched – [is] that it makes sense to bring this planning process together, especially at the national level. We very often have different focal points for climate change, desertification and biodiversity. They don’t necessarily talk to each other. They are often in different ministries.
These planning processes are often subject to different funding streams and support, so it’s actually difficult to bring them together at a national level. But it would make a lot more sense and we’ve seen the potential is big [as] the numbers, the percentages, where the plans refer to each other are not high. So there’s scope for improvement.
What one would hope is that these three COPs now can actually give a push to countries committing to bringing this together and, ideally, also to us as convention secretariats to get a mandate to support this better coordination of processes at national level.
CB: I wanted to ask about finance, because that is obviously going to be a huge talking point as well at this COP. How would you like to see developed countries showing leadership at COP16 in meeting the nature finance target in particular of hitting at least $20 billion per year by 2025 for developing countries? Are you optimistic that this goal will be achieved?
AS: Well, that’s a difficult question. First of all, the goal on ODA [official development assistance] is part of a broader financing goal, of course. But since you asked specifically about ODA, we don’t have figures beyond 2022. The figures that the OECD [Organisation for Economic Co-operation and Development] has published, which you may have seen, indicate a very positive trend on nature finance up to 2022. We have no reason to believe that this trend would have changed and if the trend persists, we are probably on a good way towards the $20 billion by 2025.
From the perspective of many developing countries, I think the expectation was that more funds would have been put into the newly created Global Biodiversity Framework Fund at the GEF [Global Environment Facility]. So we hope that at the COP, indeed, new pledges will be made so that this fund will see more funding.
But I think we have to realise that most biodiversity finance streams are bilateral streams and don’t go through the funds. We also have to see that in addition to the framework fund, there is the Kunming Biodiversity Fund that China put in place that has also been capitalised with $200 million.
So there is movement across the world and, therefore, I think the outlook is broadly positive. Is it enough? No. Does it have to be scaled up? Absolutely. I think we will have good discussions at COP [on] how that can be done. And, of course, we also need to continue in the same vein as we discussed before, how the climate and biodiversity crises overlap and how also these funding streams, to an extent, overlap.
CB: Looking then at Colombia’s role as host country for this COP and Susana Muhamad’s role as summit president. Do you think that the profile of both the country and her as president will have a positive impact on the outcome of the talks? Especially compared to COP15, which didn’t end up taking place in the host country of China.
AS: At COP15, we had a very active presidency and then supported by an active host. So there was almost a beautiful coming together of China and Canada and we had an excellent outcome.
For COP16, yes, I think the fact, first of all, that the COP is taking place in a biodiversity-rich country is already positive. We have seen Colombia take leadership on biodiversity issues for many years. Including, for example, at COP15, when they led with Germany on the accelerator initiative.
There’s a lot that this country can bring to the debate including, incidentally, in terms of a very lively Indigenous community and a lot of traditional knowledge and discussion around that which will, in any case, take place at our COP.
So I think Colombia is an excellent host. They’ve made a lot of efforts to make this COP a success. And in Susana Muhamad, we have a very knowledgeable and a very charismatic and very dedicated COP host. So I think the ingredients are in place for this to be a very good, successful COP.
CB: Also, though, their role as host has not been without a couple of difficulties along the way. There were reports during the summer that there was a dissident rebel group threatening to disrupt the COP, although the threat has since been withdrawn. Also there are peace talks ongoing between the government and the ELN [National Liberation Army]. Are you, and the CBD in general, reassured about the security of the summit?
AS: Yes, we are. Of course, we know that Colombia is a country with an ongoing internal conflict. We know that there is an ongoing peace process to which the government is dedicating a lot of attention. We have worked very closely with the government, both at country level, then also at sub-national level with the Valle del Cauca and with the city to look at the security plans. We have seen the government come together, ministries across the board working on that. So, yes, I think, we are reassured that good security arrangements are in place both in the city of Cali and for the COP specifically as well.
CB: There are going to be several world leaders there that you were announcing a couple of weeks ago – Lula, the president of Brazil, the newly inaugurated President Sheinbaum in Mexico, alongside other world leaders. This is definitely a change of pace from COP15 and previous biodiversity COPs, where there was not this same politicking around it, especially compared to climate COPs. Do you think that this will help to bring more attention to the biodiversity COP, given that it generally receives a fraction of the coverage and the interest compared to the climate COP in particular? Was it the aim of inviting world leaders to amp up the profile?
AS: Yes to both. I think the presence of world leaders amplifies the profile of the convention. I think the intention of Colombia as a host – and, of course, we very much support that – is to demonstrate that the nature crisis has to be understood as being at the same level of seriousness as the climate crisis and therefore also requiring the same level of political attention.
That’s why they have invited heads of state and government to come to the COP. We think that’s a very good signal, especially because, as I think Susana Muhamad always indicates, and I mentioned earlier, we will not be able to look at climate change in isolation from the nature and biodiversity crisis.
So if we want the climate targets of 1.5C to be within reach, we really also need to look at how nature can contribute. And by bringing heads of state and government that are talking about this a lot to our COP, I think we will succeed more to get this message heard by a wider audience.
CB: My next question is slightly off topic but, out of curiosity, has the CBD engaged in any talks with the US in recent years about them ratifying the convention? And also, could the upcoming presidential election have any impact on this prospect?
AS: I mean, we always have contacts with the United States. We’re just across the border [at the CBD headquarters in Montreal], so we regularly talk to the government. The United States are always participating at the COPs with reasonably big delegations. They are engaged in all our meetings. I’m not aware that we have had specific discussions about ratification and, at the same level, whatever the outcome of the next elections will be, ratification has not been a subject that was actively discussed in the US recently. As well as I know, inter alia, because it needs a congressional majority that has not been available in the past years.
CB: Looking at your own background in the European Commission, you must be well versed in figuring out how to make policies work for both developed and developing countries. Particularly around policies like the anti-deforestation regulation, which was recently postponed for a year. How do you plan to ensure that the input of biodiverse, developing countries and also Indigenous peoples and local communities, these other key stakeholders, remain at the front and centre of COP16 talks?
AS: Well, especially on this latter issue, on the Indigenous peoples and local communities, this is actually a big issue on our agenda and also one that’s very important for Colombia. [It’s] where a lot of mobilisation has taken place over the past weeks, of Indigenous groups coming together and formulating their policies.
So what we think will happen at the COP is that we will adopt a new work programme for Indigenous people, but possibly also look at the upgrading of what we currently have as a working group to a proper subsidiary body. So that would elevate, in a way, the voice of Indigenous people and all the traditional knowledge they bring to the debate.
For developing countries, I mean more broadly, I think everybody realises that, like climate change, biodiversity may be a localised issue, but it is a global challenge. So we need action at all levels and the biodiversity-rich countries are, notably, [largely] in the global south.
So that’s why we have such a big discussion on resource mobilisation, why we have a big discussion on sharing of expertise, of knowledge and technology. This will have to continue at COP. There’s a lot of south-south cooperation that we also like to support and there’s a lot of, let’s say, willingness and mobilisation across the global south that will also come with big delegations that we hope to support through the COP discussions and also through the decisions that are being taken and through the various support programmes that UN agencies like UNEP [UN Environment Programme] and UNDP [UN Development Programme] run, for example, in supporting NBSAP processes and others.
CB: Looking far ahead into the future, it was recently confirmed that Azerbaijan has put its name forward to host COP17, the next UN biodiversity summit. Firstly, what is your reaction to that, especially given some of the controversies around their hosting of the climate COP – given that they are a petrostate – and also their human rights issues? Also, when will the next host be decided? Will the announcement be made at the end of COP16?
AS: The way that works for the biodiversity convention, we adopted a decision I think at COP13 that looks at a regional rotation. And, indeed, COP17 should be hosted by the eastern European group. We have two offers on the table at the moment – Azerbaijan and Armenia. If there would be no consensus in the eastern European group, that they would sort of put forward one or the other, the way this works for us is that this is a procedural decision. Such procedural decisions could be taken by vote at the end of the COP.
CB: What is your reaction then to both Azerbaijan and Armenia having put their names forward for it? Are you excited about either option?
AS: Well, hosting a COP is a huge responsibility and I think Azerbaijan experiences this now as they’re getting ready to host the climate COP. If a country puts itself forward, it puts its national policies under a global spotlight. So I think it takes courage to do it and we’re grateful that we have two candidates that want to host us in 2026.
CB: Thank you for taking the time to speak, I really appreciate it. Is there anything else you wanted to add, or anything else you think would be good to mention just two weeks out from the start of COP?
AS: As you mentioned yourself in the beginning, there are important decisions to be taken. You might think it’s just an implementation COP, but it is an implementation COP. And implementation, in many ways, is just as important or more important than making new commitments.
Maybe one area I would highlight in addition to the ones we discussed, and that’s that of digital sequencing information [DSI]. At COP15, we already put in place a decision to say that we wanted a multilateral mechanism that looks at how this digital sequence information from genetic information, [how] the benefits of it could be shared more equitably.
So we are looking forward to this complex issue now being resolved at COP16 with such a mechanism being instituted. Because we think this could actually generate considerable finance streams for biodiversity-rich countries and, therefore, it’s important that we move ahead with it and put in place a mechanism that is workable for all countries and that allows us, in a way, to move ahead with this mindset shift that we see in the business world. With more and more businesses coming to the discussion, but also the businesses realising that you cannot build your business model and your business success on nature for free.
So there is a price to be paid and the sequencing information discussion sort of exemplifies this very well. As, in general, the fact that business is now coming to the table in greater numbers and is asking a lot of questions about how they can measure their impacts, how they can disclose what are the right metrics.
All these discussions that will take place at COP16, I think, are very important given that business is not only very dependent on nature, but also has important impacts on nature. They just need to be part of the discussion along with everybody else.
CB: On that, on both DSI and also businesses showing up in greater numbers at COP, are you worried about a potential impact of lobbying weakening the text around DSI, in particular now that the talks that have been ongoing for so long are reaching their end stage and everything is going to hit the fan, essentially, with businesses and countries needing to start taking these things into account? Are you worried that there could be a ramping up of this lobbying at this COP?
AS: Well, I think there are different groups of businesses that will be involved at COP, and there’s only a certain subset of businesses that might be concerned in the first place by the DSI.
So yes, of course, if you are a company, you are worried about how this mechanism will work and I think they will come to the table expressing their concerns and arguing for a workable mechanism.
But we have heard lots of companies from sectors that are most concerned, of pharmaceuticals, biotech, etc, that have actually already done this what I call the ‘mindset shift’ and that have said ‘we realise this is something we need to do, we want to do, but we also want it to be workable’. And I think that’s an important consideration and they will bring that to the table for sure.
CB: Great, thanks again.
AS: Thank you and see you in Cali.

Colombia proposes expert group to advance talks on minerals agreement
Colombia wants countries to discuss options for a global agreement to ensure that the extraction, processing and recycling of minerals – including those needed for the clean energy transition – don’t harm the environment and human wellbeing.
The mineral-rich nation is proposing to create an expert group to “identify options for international instruments, including global and legally-binding instruments, for coordinated global action on the environmentally sound management of minerals and metals through [their] full lifecyle”.
Colombia hopes this will eventually lead to an agreement on the need for an international treaty to define mandatory rules and standards that would make mineral value chains more transparent and accountable.
The proposal was set out in a draft resolution submitted to the UN Environment Assembly (UNEA) earlier this week and seen by Climate Home News. UNEA, which is constituted of all UN member states, is the world’s top decision-making body for matters relating to the environment. The assembly’s seventh session will meet in Kenya in December to vote on countries’ proposals.
Soaring demand for the minerals used to manufacture clean energy technologies and electric vehicles, as well as in the digital, construction and defence industries have led to growing environmental destruction, human rights violations and social conflict.
Colombia argues there is an “urgent need” to strengthen global cooperation and governance to reduce the risks to people and the planet.
Options for a global minerals agreement
The proposal is among a flurry of initiatives to strength global mineral governance at a time when booming demand is putting pressure on new mining projects.
Colombia, which produces emeralds, gold, platinum and silver for exports, first proposed the idea for a binding international agreement on minerals traceability and accountability on the sidelines of the UN biodiversity talks it hosted in October 2024.
Since then, the South American nation has been quietly trying to drum up support for the idea, especially among African and European nations.
Its draft resolution to UNEA7 contains very few details, leaving it open for countries to discuss what kind of global instrument would be best suited to make mineral supply chains more transparent and sustainable.
Does the world need a global treaty on energy transition minerals?
Colombia says it wants the expert group to build on other UN initiatives, including a UN Panel on Critical Energy Transition Minerals, which set out seven principles to ensure the mining, processing and recycling of energy transition minerals are done responsibly and benefit everyone.
The group would include technical experts and representatives from international and regional conventions, major country groupings as well as relevant stakeholders.
It would examine the feasibility and effectiveness of different options for a global agreement, consider their costs and identify measures to support countries to implement what is agreed.
The resolution also calls for one or two meetings for member states to discuss the idea before the UNEA8 session planned in late 2027, when countries would decide on a way forward.
No time to lose for treaty negotiations
Colombia’s efforts to advance global talks on mineral supply chains have been welcomed by resource experts and campaigners. But not everyone agrees on the best strategy to move the discussion forward at a time when multilateralism is coming under attack.
Johanna Sydow, a resource policy expert who heads the international environmental policy division of the Heinrich-Böll Foundation, said she had hoped that the resolution would explicitly call for negotiations to begin on an international minerals treaty.
“Treaty negotiations take a long time. If you don’t even start with it now, it will take even longer. I don’t see how in two or three years it will be easier to come to an agreement,” she told Climate Home.
Despite the geopolitical challenges, “we need joint rules to prevent a huge race to the bottom for [mineral] standards”. That could start with a group of countries coming together and starting to enforce joint standards for mining, processing and recycling minerals, she said.
But any meaningful global agreement on mineral supply chains would require backing from China, the world’s largest processor of minerals, which dominates most of the supply chains. And with Colombia heading for an election in May, it will need all the support it can get to move its proposal forward.
‘Voluntary initiative won’t cut it’
Juliana Peña Niño, Colombia country manager at the Natural Resource Governance Institute, is more optimistic. “Colombia’s leadership towards fairer mineral value chains is a welcome step,” she told Climate Home News.
“At UNEA7, we need an ambitious debate that gives the proposed expert group a clear mandate to advance concrete next steps — not delay decisions — and that puts the voices of those most affected at the centre. One thing is clear: the path forward must ultimately deliver a binding instrument, as yet another voluntary initiative simply won’t cut it,” she said.
More than 50 civil society groups spanning Latin America, Africa and Europe previously described Colombia’s work on the issue as “a chance to build a new global paradigm rooted in environmental integrity, human rights, Indigenous Peoples’ rights, justice and equity”.
“As the energy transition and digitalisation drive demand for minerals, we cannot afford to repeat old extractive models built on asymmetry – we must redefine them,” they wrote in a statement.

DeBriefed 3 October 2025: UK political gap on climate widens; Fossil-fuelled Typhoon Ragasa; ‘Overshoot’ unknowns
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Shattered climate consensus
FRACKING BAN: UK energy secretary Ed Miliband has announced that the government will bring forward its plans to permanently ban fracking, in a move designed to counter a promise from the hard-right Reform party to restart efforts to introduce the practice, the Guardian said. In the same speech, Miliband said Reform’s plans to scrap clean-energy projects would “betray” young people and future generations, the Press Association reported.
ACT AXE?: Meanwhile, Kemi Badenoch, leader of the Conservatives, pledged to scrap the 2008 Climate Change Act if elected, Bloomberg reported. It noted that the legislation was passed with cross-party support and strengthened by the Conservatives.
‘INSANE’: Badenoch faced a backlash from senior Tory figures, including ex-prime minister Theresa May, who called her pledge a “catastrophic mistake”, said the Financial Times. The newspaper added that the Conservatives were “trailing third in opinion polls”. A wide range of climate scientists also condemned the idea, describing it as “insane”, an “insult” and a “serious regression”.
Around the world
- CLIMATE CRACKDOWN: The US Department of Energy has told employees in the Office of Energy Efficiency and Renewable Energy to avoid using the term “climate change”, according to the Guardian.
- FOREST DELAY: Plans for Brazil’s COP30 flagship initiative, the tropical forests forever fund, are “suffer[ing] delays” as officials remain split on key details, Bloomberg said.
- COP MAY BE ‘SPLIT’: Australia could “split” the hosting of the COP31 climate summit in 2026 under a potential compromise with Turkey, reported the Guardian.
- DIVINE INTERVENTION: Pope Leo XIV has criticised those who minimise the “increasingly evident” impact of global warming in his first major climate speech, BBC News reported.
€44.5 billion
The cost of extreme weather and climate change in the EU in the last four years – two-and-a-half times higher than in the decade to 2019, according to a European Environment Agency report covered by the Financial Times.

Captured

Clean energy has met 100% of Great Britain’s electricity demand for a record 87 hours this year so far, according to new Carbon Brief analysis. This is up from just 2.5 hours in 2021 and 64.5 hours in all of 2024. The longest stretch of time where 100% of electricity demand was met by clean energy stands at 15 hours, from midnight on 25 May 2025 through to 3pm on 26 May, according to the analysis.
Spotlight
‘Overshoot’ unknowns
As the chances of limiting global warming to 1.5C dwindle, there is increasing focus on the prospects for “overshooting” the Paris Agreement target and then bringing temperatures back down by removing CO2 from the atmosphere.
At the first-ever Overshoot Conference in Laxenburg, Austria, Carbon Brief asks experts about the key unknowns around warming “overshoot”.
Sir Prof Jim Skea
Chair of the Intergovernmental Panel on Climate Change (IPCC) and emeritus professor at Imperial College London’s Centre for Environmental Policy
So there are huge knowledge gaps around overshoot and carbon dioxide removal (CDR). As it’s very clear from the themes of this conference, we don’t altogether understand how the Earth would react in taking CO2 out of the atmosphere.
We don’t understand the nature of the irreversibilities and we don’t understand the effectiveness of CDR techniques, which might themselves be influenced by the level of global warming, plus all the equity and sustainability issues surrounding using CDR techniques.
Prof Kristie Ebi
Professor at the University of Washington’s Center for Health and the Global Environment
There are all kinds of questions about adaptation and how to approach effective adaptation. At the moment, adaptation is primarily assuming a continual increase in global mean surface temperature. If there is going to be a peak – and of course, we don’t know what that peak is – then how do you start planning? Do you change your planning?
There are places, for instance when thinking about hard infrastructure, [where overshoot] may result in a change in your plan – because as you come down the backside, maybe the need would be less. For example, when building a bridge taller. And when implementing early warning systems, how do you take into account that there will be a peak and ultimately a decline? There is almost no work in that. I would say that’s one of the critical unknowns.
Dr James Fletcher
Former minister for public service, sustainable development, energy, science and technology for Saint Lucia and negotiator at COP21 in Paris.
The key unknown is where we’re going to land. At what point will we peak [temperatures] before we start going down and how long will we stay in that overshoot period? That is a scary thing. Yes, there will be overshoot, but at what point will that overshoot peak? Are we peaking at 1.6C, 1.7C, 2.1C?
All of these are scary scenarios for small island developing states – anything above 1.5C is scary. Every fraction of a degree matters to us. Where we peak is very important and how long we stay in this overshoot period is equally important. That’s when you start getting into very serious, irreversible impacts and tipping points.

[A key unknown] is whether countries are really willing to commit to net-negative trajectories. We are assuming, in science, global pathways going net-negative, with hardly any country saying they want to go there. So maybe it is just an academic thought experiment. So we don’t know yet if [overshoot] is even relevant. It is relevant in the sense that if we do, [the] 1.5C [target] stays on the table. But I think the next phase needs to be that countries – or the UNFCCC as a whole – needs to decide what they want to do.

Professor of international environmental law at the University of Oxford
I think there are several scientific unknowns, but I would like to focus on the governance unknowns with respect to overshoot. To me, a key governance unknown is the extent to which our current legal and regulatory architecture – across levels of governance, so domestic, regional and international – will actually be responsive to the needs of an overshoot world and the consequences of actually not having regulatory and governance architectures in place to address overshoot.
