The first three quarters of 2023 has seen exceptional heat globally, putting 2023 on track to be the warmest year since records began in the mid-1800s, and likely for millennia before as well.
The past four months, in particular, have far exceeded any prior records, with September smashing the prior record by around 0.5C.
In this latest “state of the climate” quarterly update, Carbon Brief finds:
- June, July, August, September and (very likely) October were the warmest respective months since records began.
- 2023 is now virtually certain to be the hottest year on record globally.
- A strong El Niño is expected to persist until mid-2024 in the majority of El Niño Southern Oscillation (ENSO) forecast models.
- October is likely to be extremely warm based on daily data so far, though not quite as unusual as September.
- While the exceptional warmth of the last few months is primarily driven by a strong El Niño on top of human-driven warming, other contributing factors include an uptick in the 11-year solar cycle, an unusual volcanic eruption last year and a 2020 phaseout of planet-cooling sulphur dioxide in marine shipping fuels.
- Ocean heat content set a new record in September and has increased substantially over the past 12 months.
- Antarctic sea ice has been exceptionally far below the prior record low for the past six months, while Arctic sea ice remains at the low end of the historical range.
- Global temperatures are closely aligned with the projections from climate models.
Global temperatures have soared in recent months
After a cool start due to an unusually persistent “triple dip” La Niña event, global temperatures have soared in recent months driven by rapidly growing El Niño conditions.
This short-term natural variability builds on top of the roughly 1.3C warming that has occurred since the mid-1800s due to human emissions of CO2 and other greenhouse gases.
The figure below shows how global temperature so far in 2023 (black line) compares to each month in different years over the prior decade (coloured lines) in the Berkeley Earth surface temperature dataset.

Every month from June onward this year has set a clear record, with July, August and September shattering prior records by at least 0.3C (and around 0.5C in the case of September). The exceptional summer warmth means that it is now virtually certain that 2023 will be the warmest year on record.
In this latest quarterly state of the climate assessment, Carbon Brief analysed records from five different research groups that report global surface temperature records: NASA’s GISTEMP; NOAA’s GlobalTemp; Hadley/UEA’s HadCRUT5; Berkeley Earth; and Copernicus/ECMWF.
The figure below shows the annual temperatures from each of these groups since 1970, along with the average over the first nine months of 2023. (Note: at the time of writing, September data was not yet available for the Hadley/UEA record.)

Annual global mean surface temperatures from NASA GISTEMP, NOAA GlobalTemp, Hadley/UEA HadCRUT5, Berkeley Earth and Copernicus/ECMWF (lines), along with 2023 temperatures to date (January-September, coloured shapes). Each series is aligned by using a 1981-2010 baseline, with warming since pre-industrial based on HadCRUT5 values from the 1850-1899 to 1981-2010 periods. Chart by Carbon Brief.
The globe as a whole has warmed around 1C since 1970, with strong agreement between different global temperature records. All show that year-to-date 2023 records are higher than any prior annual record. However, there are larger differences between temperature records further back in time (particularly pre-1900) due to sparser observations and a resulting greater sensitivity to how gaps between measurements are filled in.
This year started out a bit on the colder side in all the different temperature records, with January only the seventh warmest January on record and February only the fourth or fifth warmest. March was the second warmest on record, April the fourth or fifth, and May the third warmest across all datasets.
However, from June onward each month has been unambiguously the warmest on record across all the different datasets. The respective rankings of each month in each dataset are shown below.
| GISTEMP | HadCRUT5 | NOAA | Berkeley | Copernicus | |
|---|---|---|---|---|---|
| Jan | 7th | 7th | 7th | 7th | 7th |
| Feb | 4th | 4th | 4th | 5th | 5th |
| Mar | 2nd | 2nd | 2nd | 2nd | 2nd |
| April | 4th | 4th | 5th | 4th | 5th |
| May | 3rd | 3rd | 3rd | 3rd | 3rd |
| June | 1st | 1st | 1st | 1st | 1st |
| July | 1st | 1st | 1st | 1st | 1st |
| Aug | 1st | 1st | 1st | 1st | 1st |
| Sept | 1st | TBC | 1st | 1st | 1st |
Rankings of 2023 global temperature by month across different datasets.
The continued strengthening of El Niño over the next few months means that it is likely that this streak of record-setting warmth will continue.
The figure below shows a range of different ENSO forecast models produced by different scientific groups. The values shown are sea surface temperature variations in the tropical Pacific – the El Niño 3.4 region – for three-month periods.

Virtually all models expect El Niño conditions to remain until early-to-mid 2024. Most models project a strong El Niño (>1.5C Niño 3.4 sea surface temperature – SST – anomaly), but relatively few expect a “super El Niño” (>2.5C) as strong as the world saw in 2015-16 or 1997-98.
Extreme heat worldwide
Record-setting global temperatures contributed to record heatwaves in many regions over the recent northern-hemisphere summer. The figure below shows the parts of the world that saw record warm or cold temperatures over the first two-thirds of 2023 (January through to September) in the Berkeley Earth dataset.
Large parts of the North Atlantic saw record warm temperatures, as did the UK, large parts of Europe, the southern US and Mexico, Central America, South America, the Caribbean, Korea, Japan and China.
Notably, no area on Earth saw record cold (or even the second-to-fifth coldest temperatures on record).

In September alone, 77 different countries – mostly in Europe and the tropics – set new monthly average records.
Virtually everywhere on the planet saw warmer-than-usual temperatures for the year so far, with the exception of the western US, India and Greenland.
The tropical Pacific shows a strong characteristic “warm tongue” associated with El Niño over the first nine months of the year. The global temperature anomalies (changes) relative to the 1951-80 period used by Berkeley Earth are shown in the map below.

October continuing the record warm streak
While global temperature records are not yet in for the full month of October 2023, real-time reanalysis products increasingly allow scientists to track global temperatures on a daily basis.
Reanalysis pulls together a huge amount of data from satellites, weather balloons, aeroplanes, weather stations, ships and buoys to provide a detailed look at how the Earth’s climate is changing in real-time.
Modern reanalysis products, such as JRA-55 and ERA5, use state-of-the-art methods to produce records that align well with traditional surface temperature datasets over recent decades.
In the figure below, Carbon Brief shows the daily global temperature anomaly values from the JRA-55 reanalysis product for each day since the record began in 1958 (grey lines). It shows the current year to date (2023) in red and the prior record warm year, 2016, in blue. Nearly every single day since mid-June 2023 has been warmer than any prior days since the JRA-55 record began in 1958 – and, potentially, much further into the past.

The heat map below focuses on 2023, showing each day in the year, with columns representing each month. The red shading shows the temperature anomaly of each day, with darker shading indicating more extreme temperatures. The map highlights how extreme the prior four months (from July onward) have been compared to the prior period.

With most of the data for the month of October now available in the JRA-55 reanalysis product, Carbon Brief estimates that October 2023 will be the warmest October on record, and is likely to exceed the prior record by at least 0.3C.
The figure below shows Carbon Brief’s estimate for October, with uncertainty intervals estimates based on the historical relationship between the first 19 days of the month available at the time of publication and the overall monthly average.

October is projected to not be quite as extreme as September’s record-shattering anomaly, but will still come in as the second highest anomaly of any month in 2023 to-date.
In addition to temperature anomalies, reanalysis products are able to provide an accurate near-real-time estimate of global absolute temperatures. The figure below shows the absolute temperature of each month of 2023 compared to all prior years in the record, with Carbon Brief’s October estimate and its uncertainties shown.

Unpacking the drivers of recent record warmth
The extreme surface temperatures seen over the past few months have triggered a broader debate in the scientific community around its potential drivers.
For example, the world has never seen a month exceed the prior monthly record by 0.5C – as experienced in September. The closest analogue is February 2016, where global temperatures beat the prior record by 0.47C.
However, February 2016 was shortly after the peak of a super El Niño event – when the effect of El Niño on global temperatures is expected to be the largest. September 2023, by contrast, occurred early in the evolution of the current El Niño event when the contribution to global temperatures is typically much smaller.
This has led to a search for alternative explanations of factors contributing to recent record warmth. While the rapid switch from modest La Niña conditions at the start of the year to growing El Niño conditions on top of human-driven warming remains the primary explanation, it cannot easily explain the full extent of extreme global temperatures over the past few months.
A number of different potential contributors to recent global temperature records have been identified, including an uptick in the 11-year solar cycle, an unusual volcanic eruption last year that put a large amount of water vapour into the stratosphere with minimal cooling sulphate aerosols, and a 2020 phaseout of planet-cooling sulphur dioxide in marine shipping fuels.
The figure below, developed by Dr Robert Rohde at Berkeley Earth, shows a current best-estimate of the impact of each of these effects over the past 10 years based on published studies to-date. The shading indicates a warming (red) or cooling (blue) influence on global temperatures.
While each of these factors are small on their own, their combined effects may be to add around 0.1C to global temperatures in 2023.

Temperatures are tracking climate model projections
Climate models provide physics-based estimates of future warming given different assumptions about future emissions, greenhouse gas concentrations and other climate-influencing factors.
The figure below shows the range of individual models forecasts featured in the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report – known collectively as the CMIP5 models – between 1970 and 2030, with grey shading and the average projection across all the models shown in black. Individual observational temperature records are represented by coloured lines.
In these models, estimates of temperatures prior to 2005 are a “hindcast” using known past climate influences, while temperatures projected after 2005 are a “forecast” based on an estimate of how things might change.

Twelve-month average global average surface temperatures from CMIP5 models and observations between 1970 and 2023. Models use RCP4.5 forcings after 2005. They include sea surface temperatures over oceans and surface air temperatures over land to match what is measured by observations. Anomalies plotted with respect to a 1981-2010 baseline. Chart by Carbon Brief.
While global temperatures were running below the pace of warming projected by climate models between 2005 and 2014, the past decade has been closer to the model average.
Currently the latter part of 2022 and early 2023 is suppressing the 12-month average compared to the most recent months, but observations are expected to be well above the model average by mid-2024.
Record high ocean heat content
Human-emitted greenhouse gases trap extra heat in the atmosphere. While some of this warms the Earth’s surface, the vast majority – around 93% – goes into the oceans. About two-thirds of this accumulates in the top 700 metres, but some also ends up in the deep oceans.
The figure below shows annual OHC estimates between 1950 and present for both the upper 700 metres (light blue shading) and 700-2000 metre (dark blue) depths of the ocean.

Monthly global ocean heat content (in zettajoules – billion trillion joules, or 10^21 joules) for the 0-700 metre and 700-2000 metre layers. Data from IAP. Chart by Carbon Brief.
In many ways, OHC represents a much better measure of climate change than global average surface temperatures. It is where most of the extra heat ends up and is much less variable on a year-to-year basis than surface temperatures.
Just about every year since 1991 has set a new OHC record, showing that heat has continued to accumulate in the Earth system as concentrations of atmospheric greenhouse gases have increased.
Over the last 12 months, ocean heat content has increased by 42 zettajoules, or around 72 times as much as the total energy produced by all human activities on Earth last year.
Record low Antarctic sea ice extent
Highly accurate observations of Arctic and Antarctic sea ice have been available since polar-observing satellites became available in the late 1970s.
The figure below shows both Arctic (red) and Antarctic (blue) sea ice extent in 2023, the historical range in the record between 1979 and 2010 (shaded areas) and the record lows (dotted black line).

The bold lines show daily 2023 values, the shaded area indicates the two standard deviation range in historical values between 1979 and 2010. The dotted black lines show the record lows for each pole. Chart by Carbon Brief.
Arctic sea ice extent during the first three quarters of 2023 has been at the low end of the historical 1979-2010 range, but has not seen any record daily lows except for a few days in February and April.
The annual minimum sea ice extent in September was the sixth lowest on record, though still well above the record low set in 2012.

Antarctic sea ice, on the other hand, has set new all-time low records for most of 2023, set a new all-time low extent in February 2023, and has been far below any prior levels ever since mid May.

Climate Change
Interview: Dr Sun Yixian on his new database tracking Chinese climate ‘leadership’
The number of global climate initiatives launched or run by China has been growing since 2009, a new study shows.
But whether this will translate into China taking up the mantle of climate leadership remains an “open question”, says Dr Sun Yixian, study co-author and professor of sustainability governance at the University of Bath.
Sun’s team has compiled a database tracking all global environmental initiatives established from the 1980s onwards that were launched or run by China.
These initiatives are either created by China or co-created with other governments, or have operations that are mainly managed by Chinese institutions.
They range from research cooperation and south-south climate funding to high-level policy signalling, such as joint statements on climate change.
In an interview with Carbon Brief, Sun discusses the key findings of the new “China’s Global Environmental Leadership” (CGEL) database.
He adds that it is not yet clear if the US withdrawal from the UN climate regime will change China’s role in global climate governance.
The conversation covers how the number of China-led initiatives has changed over time, what these projects look like and how China’s approach to climate “leadership” is changing.
The interview has been edited for length and clarity.
- Sun on the types of climate initiatives: “There are all different kinds of initiatives – we have these typologies of governance functions, including sharing information and building platforms, or developing capacity – capacity building activities, which can be training delivered by China to other countries. Or also by providing funding, for example.”
- On the rise in new climate initiatives: “From after 2009 and 2010, we’ve seen many initiatives – of course, more and more over the last 10 years, and even the last five years, from 2021…have been created.”
- On the impact of the Trump administration: “The shift of the US under the second Trump administration will probably help Chinese initiatives get more traction from their international partners…Whether or not this will translate into new initiatives or strengthen existing initiatives, I think that’s an open question.”
- On a growing focus on multilateral programmes: “What we have seen is a very clear upward trend of transnational initiatives with a global scope. That means they operate in more than two continents. So, in that sense, what we can see is, actually, China is moving from this bilateral engagement model to more kind of global engagement and trying to project its influence at the global scale.”
- On a climate leadership ‘mindset’: “[Leading Chinese experts] said the government, and also people in China, are not ready to become a global leader. But, at the same time…in climate governance, but also in clean-energy supply chains – China is playing a leading role. So, I think the question is whether this…will translate into the understanding, or mindsets, of people, including policymakers or decision-makers in the country.”
- On the future of China’s climate engagement: “My read is that China is willing to share more knowledge, and technology as well, through its international global engagements…But, at the same time, I think, it is not a given. It depends on how countries can make arrangements with China, how they can also propose viable solutions in terms of absorbing Chinese technologies.”
- On the future of multilateral climate negotiations: Multilateralism is a very important principle, championed in almost all the initiatives. That means China is not going to abandon multilateral processes. Also, we have done some work looking at the alignment of Chinese climate initiatives with existing UN institutions and frameworks, and we also see very close alignment.
Carbon Brief: Thank you for joining us, Yixian. Your team has compiled a database of China’s “environmental leadership”. What do you mean by leadership and what did you find in relation to climate change?
Sun Yixian: Thanks Anika, it’s great to speak to Carbon Brief. Leadership is a very contested concept in social science, or especially in international relations. This is why we were very cautious when we thought about the name of this dataset, but we thought it was a good way to capture what we’re trying to do.
In this project, what we are trying to look at is China’s role in global environmental governance – China’s shifting role, especially from a more passive participant in global governance processes to play a more proactive role in developing or managing its own initiatives on transnational or cross-border environmental governance.
So, [this includes] different environmental issues, but, of course, we found that climate change is a very important issue area. By leading, we are using the concept of governance – in a sense that we are looking at the initiatives where Chinese actors claim some authority over other audiences towards certain public goods. So, it’s trying to provide public goods, in different ways. We have come up with a typology of different governance functions, trying to look at what specific activities Chinese actors are doing, or what kind of public goods Chinese actors are delivering, to the audiences of different initiatives.
And by audience we mean…international actors. So, that means we are not interested in what China is doing domestically, but beyond its borders.
CB: Could you explain what some of these climate initiatives look like in practice?
SY: This is very important, because it sounds very abstract if we just talk about leadership. In practical terms, there are all different kinds of initiatives – we have these typologies of governance functions, including sharing information and building platforms, or developing capacity – capacity building activities, which can be training delivered by China to other countries.
Or also by providing funding, for example, China has created this south-south climate fund. It can also include research collaboration or producing knowledge – mainly between research institutes.
It can be traditional leadership activities, in the sense of developing certain international regulatory frameworks or rules or standards – we call this rulemaking and standard-setting. It can also be pilot projects. China sometimes can start to work directly with some international partners to trial new ideas and new practices – what we call direct actions.
These are the different types of leadership activities that we look at and we actually code each initiative that meets the criteria of our database according to this topology, to try to look at what [the Chinese government] are looking at.
Some initiatives can do multiple things at the same time…One example is the Global Energy Interconnection Development and Cooperation Organization [GEIDCO]. [This was] initially created by the State Grid of China to try to promote clean energy and energy interconnections.
This initiative will deliver different types of activities, including building the capacity of some developing countries on energy and electricity grids, and also, for example, developing an international platform – they have annual international meeting and a lot of information-sharing activities, and engagement at UN meetings, including at COP side-events, and also directly engaging with some international organisations.
So, this is an example of the type of leadership initiative that has been included in our database.
CB: And would you say that there’s one particular type of activity that dominates, in terms of China’s climate leadership? Or is it very evenly split against all of the different types?
SY: This is also one of the main findings in our work. In the first paper we published to highlight the key patterns from the dataset, we highlighted that there’s a very uneven distribution in terms of what China tries to deliver or to promote, itself, internationally on environmental governance.
There have been a lot of initiatives focusing on sharing information and building platforms and this is the most dominant category – across all environmental issues, but the same pattern applies to climate change.
In the first article we published in the Earth Systems Governance journal, we looked at the whole dataset, but we are also developing a few studies, currently under review. One paper particularly looks at climate initiatives and it’s the same pattern: information-sharing and networking.
At the same time, the least frequent or popular type is the provision of funding – creating some financing programmes to directly give funding to international partners. I think this reflects China’s position on environmental or climate finance, especially internationally.

[China’s] not trying just to provide money, but really think about how to support other countries on more practical, more pragmatic terms. This is why I think that after information-sharing, what we have seen is capacity-building activities, which have also been quite frequently used by Chinese initiatives when collaborating with their international partners. This also explains China’s logic to teach [others] how to develop things, but not just giving money.
The other important category is research collaboration and knowledge production. This has been mainly led by research institutes in China, such as the Chinese Academy of Sciences, especially with a strong focus on scientific co-production.
But, lately, we have also seen more and more initiatives focused on sharing knowledge not just about science itself, but sometimes also on the social sciences side – the experiences of China as a whole. China’s experiences can also be learned from by other countries, especially in the global south.
These are just some examples, but the overall pattern is [a focus on] information-sharing, capacity building and knowledge production and not too much on provision of funding.
CB: You mentioned the GEIDCO example earlier. How much of a tangible impact would you say a lot of these initiatives have? Are they very high-level, strategic and quite abstract? Or do they kind of result in programmes on the ground?
SY: That’s a very interesting question – the answer is that it really varies. GEIDCO, as you mentioned, is a very high-level initiative. I think, initially, the idea of energy interconnection was proposed by President Xi himself. Now, of course, GEIDCO, with the backing of the State Grid, does a lot of high-level [national planning] and trans-national [grid network] planning work with developing countries.
But, at the same time, there are also a lot of grounded, locally focused initiatives. A lot, for example, are co-developed between China – especially supported by the Ministry of Ecology and Environment [MEE] – and UNEP [United Nations Environment Programme] in, for example, Africa and Southeast Asia. [This includes] some projects looking at climate adaptation and resilience. But these are more small-scale projects.
So, in our database – and I welcome your readers to explore the database itself that you can see – there are a big variety of initiatives and their scope, their mission and their intended outcomes or impacts vary significantly.
But we are just providing this public resource. Hopefully, people can use it to further explore, for example, the question of the impact or outcome. At this stage, we’re not going to assess what has been delivered, but I think if we can take, for example, a case-study approach – trying to trace what has been done, what has been delivered – this could also be a very interesting research agenda.
CB: Is there a particular time from when China’s interest in engaging on climate change started, or has this been a very long-term process?
SY: In our database, we really wanted to capture the historical trend. That’s why we looked back from early on – [we focused on] from the beginning of this century, but also traced initiatives that had been created even earlier but became active in the 21st century.
So we can [see that,] already in the late 1980s or 90s, there were some initiatives in the area of climate change. But, most importantly, the majority of the initiatives were started after 2008, mainly in the 2010s. We can see a very clear upward trend. It was not shown directly in our recently published article, but it’s in the database and we have looked at the data and produced a graph for other studies we are currently developing.
Really, from after 2009 and 2010, we’ve seen many initiatives – of course, more and more over the last 10 years, and, even the last five years, from 2021, we still see more and more initiatives have been created.

This timeframe corresponds to China’s shifting international role, to move from [being] a more regional power, a large developing country, to a global superpower, and trying to project its influence globally.
That also correlates with, for example, the belt and road initiative and lately the global development initiative – China is trying to also use climate change in this broader policy framework and trying to promote and support climate action in different parts of the world.
CB: The database stops at 2024 – just before the current administration withdrew the US from the Paris Agreement. Have you noticed any changes in China’s global climate engagements following this?
SY: I would say the trend is a continuous one, even with the withdrawal of the US from the Paris Agreement and lately from the UNFCCC. Because, as I mentioned earlier, over the past 10 years, we have seen this upward trend, with more and more new initiatives created by Chinese actors.
But I think the shift of the US under the second Trump administration will probably help Chinese initiatives get more traction from their international partners – or countries or actors that haven’t been engaged very closely with China – to work more closely with China.
Whether or not this will translate into new initiatives or strengthen existing initiatives, I think that’s an open question.
We really want to explore [this] further. Something I didn’t mention earlier is we are publishing this data set as version one, we want to keep updating on a regular basis. We hope we’ll have versions two or three out, maybe every two years. We’ll see how things go, but I think this is a very important question.
CB: Looking at how China is engaging with all of these different countries – as you mentioned, more and more potentially wanting to work with it following the US’s withdrawal – do you get the sense that the Chinese government prefers to engage with countries bilaterally, on a one-to-one basis, or are they also engaging at the regional and multilateral levels?
SY: This is a great question. This is also an important finding from our work, because the conventional understanding is that China prefers to engage with countries bilaterally.
But, if we look at our database, what we can see is that, actually, China has developed more and more transnational initiatives – meaning that it also involves non-state actors or [works] beyond the traditional multilateral processes and [develops initiatives] with a global scope.
If we look at the historical trends, initially – especially up to 2010 – there were a lot of bilateral initiatives. Most cases in our database are bilateral initiatives.
But, lately, I think this trend is shifting. Still, I think there are many more bilateral initiatives than multilateral and transnational initiatives.
How we differentiate leadership activities of Chinese [state] actors across different levels [affects the trend], but, lately, what we have seen is a very clear upward trend of transnational initiatives with a global scope. That means they operate in more than two continents.
So, in that sense, what we can see is, actually, China is moving from this bilateral engagement model to more kind of global engagement and trying to project its influence at the global scale.
I think this is also quite interesting, to understand how not only the government, but also lots of Chinese actors – including, for example, businesses and civil society actors – are trying to project and their footprint globally.
And also I think this reflects a shifting global role of China, in general. We can further explore what the implications of this phenomenon are. This is some ongoing research I’m doing – trying to understand how actors in different parts of the world react or perceive this changing rule of China and how such engagement between China and different countries shape, or reshape, the sustainability transition.
CB: You mentioned just then that there’s not just the Chinese government, but also civil society, businesses and other non-state actors. What role do you think these non-state organisations play in the country’s overall climate strategy and climate engagement?
SY: Let me start with the caveat that, first of all, as shown in our database, the government, or state actors, still play a very important role – especially central government agencies, for example, the MEE [Ministry of Ecology and Environment] or NDRC [National Development and Reform Commission].
But, at the same time, especially over the last 10 years, what we have seen is that non-state actors have become more active and engaged more, in various ways, in leading climate initiatives beyond China’s borders.
This means, sometimes, they collaborate with state actors to co-develop certain initiatives. Sometimes, they develop their own initiatives with, of course, some support from the state. One thing we need to bear in mind is, in China, it’s almost impossible to [avoid involving] the state. At least, you have to closely align with the strategy of the government.
But, at the same time, what we can see is the agency of these actors. They have developed or showed the ambition to develop certain initiatives, including, for example, standards in the critical mineral space, to provide guidelines to companies for their overseas activities.
Similarly, some civil society actors, [such as] research institutes, also want to claim their leadership in a global sphere, trying to showcase how they can lead certain activities and show how their expertise or their knowledge can support countries or actors in other parts of the world.
CB: On the standards-setting point, is that something where it might be led by one Chinese company with multiple partners – whether it be from one country or from various different countries in a region? Or is it a broad spectrum of Chinese companies coming together saying that we want to work with Chile, Zimbabwe etc, on mining standards? Is it very representative of the industry, or does it tend to be quite piecemeal?
SY: This is an inclusion criteria for the databases. We [only] look at the initiatives that are, to a large extent, institutionalised. It’s not that company’s claim that “we are doing this”. If we can’t track down any information or find any records then we cannot include things like that in our database.
That means we only tend to look at initiatives that are well-developed. These are often, for example, developed by national industry associations. They try to convene different companies together and try to collaborate with, or coordinate, different actors along supply chains and also across sectors or industries.
When they work with different international partners, this is also a question I think we need to further explore, using our data set to try to look at – sometimes I think it’s not easy for us to do everything! – but try to look at what kind of partners they select and how they get involved with partners in different countries or different regions.
But I think this probably requires some other methodologies to look at, or maybe zoom out to specific cases.
This is similar – I always want to use this as a comparison – when we started [seeing] this phenomenon in Europe or in North America, for example, where companies start to take climate actions, we didn’t really pay a lot of attention to how and who they work with, as long as they say: “We are trying to support global climate action.”
But, nowadays, when it comes to the question of China, people start to be interested in who they work with. But if we look at the narrative and discourse of these initiatives, they say as well: “We want to support actions around the world.”
They don’t always specify [the geographic scope of their standard-setting work], but if we further zoom into where they are working and why they work in specific areas or regions, this is also an interesting question – I think there is also a question of politics or political economy there. I would encourage researchers to use our dataset to further explore that kind of question.
CB: Zooming back out – the theme of the data set is environmental leadership, but – at least in global climate negotiations – Chinese officials have eschewed being called a climate leader. Your database seems to show an uptick in activity that could be defined as leadership. Would you say that China wants to be seen as a climate leader?
SY: This is a very strong claim, so I probably would not say [so] – also, it’s very subjective, depending on who you ask this question to and how people perceive it.
Let me frame me this way – let’s separate multilateral negotiation processes from what the country or different actors are doing. Of course, for leadership, another way to measure this is to see the performance itself.
But, in the end, I think we also tried to be very reflective when we developed this work to acknowledge the subjectivity of leadership and the relational nature of leadership. That means that, if you want to be a leader, others need to acknowledge your leadership or recognise this status.
But this is why I think it comes to an interesting question about what’s the role of China and how different actors perceive China’s role in today’s global climate governance.
In multilateral negotiation processes, we are entering into the implementation phase for the Paris Agreement. That means it is very difficult to create new agendas at this stage. [Instead the focus is] trying to see if countries can deliver what they have done.
Of course, I think there is a question of ambition in terms of updating your nationally determined contributions. So, there is an ambition question – there is a performance question.
If we want to see whether China is becoming a leader, we have to look at how fast, for example, China is accelerating its energy transition, trying to reduce – of course, some data shows China has already peaked its emissions – but maybe, how fast China can reduce its emissions.
Then, in terms of international engagement, what our data is trying to show is that China has become more proactive in that space. The question is also if this engagement translates into some progress in different parts of the world – if China is actually helping. We need more data to do this kind of impact assessment.
But, at the same time, I think the question of whether the Chinese government wants itself to be seen as a leader – this is also an interesting question. Depending on who they want to engage with, in different fora or on different platforms, the answer may be different.
I just want to quote, when I was in China a few months ago, we had some dialogues with leading Chinese experts. They said the government – and also people in China – are not ready to become a global leader. But, at the same time, I think, what China is doing or the role of the country – in climate governance, but also in clean-energy supply chains – China is playing a leading role.
So, I think the question is whether this physical change that has already happened will translate into the understanding, or mindsets, of people, including policymakers or decision-makers in the country.
I think this is a question that China needs to figure out, itself. Then, of course, there will be implications for China’s strategy for engaging with the rest of the world, especially on climate change.
CB: And what do you think China’s climate engagements will look like in 5-10 years from now?
SY: I think, from an energy-transition perspective – let me start from there – China is going to be, at the least, more proactive in promoting energy transition, because it aligns with China’s economic interests and, to a certain extent, its political interest as well, to support energy transitions around the world.
The key question is what role China can play in doing that. Of course, there is the question of trade, of tariffs. There is also the question of investment, intellectual property and technology transfer.
My read is that China is willing to share more knowledge, and technology as well, through its international global engagements, to support other countries. But, at the same time, I think, it is not a given. It depends on how countries can make arrangements with China, how they can also propose some viable solutions in terms of absorbing Chinese technologies.
What we have seen is a lot of countries, especially in the global south, have benefited already, or are in the process of benefiting from, affordable technologies produced by China.
But, at the same time, this is not sustainable – at least from an economic point of view – not a sustainable situation in the sense that these countries also need to find a way to move themselves upward in supply chains and try to absorb some technologies. How they can work with China [to achieve this] – that’s a very important question to me and also my team. We want to do more research in that area.
This is from the energy-transition perspective. But then, if we look at multilateral processes, I would say China is very committed to multilateralism. If we look at all the discourse, including the cases in our database – we have done some text analysis looking at the narrative discourse of the vision of these initiatives. Multilateralism is a very important principle, championed in almost all the initiatives. That means China is not going to abandon multilateral processes.
Also, we have done some work looking at the alignment of Chinese climate initiatives with existing UN institutions and frameworks, and we also see very close alignment.
So, I think this pattern will probably last. At the same time, because – depending on the other important countries’ climate policies, for example, the US – back to your question about the leadership in multilateral processes, how proactive and how ambitious China wants to be in taking on this leadership position in multilateral processes is still an open question.
This also depends on the concept of leadership in different cultures.
Whether China wants to take over the US to become the only superpower of a global system – I think this is probably very unlikely. China may want to figure out a slightly different model. Even if, physically, it’s one of the most, or the most, important or powerful countries in the world, how using how the country can use this position to support or guide the governance of global challenges, this is probably slightly different from the views or understanding of, for example, European and other global north countries.
The question is how China can propose a slightly different model – still in the current multilateral system – for governing global challenges, including climate change. This is really important. I don’t have an answer, so that’s why we will continue to look at this question and try to use our research to help people understand what role China can play in global climate governance.

India looks to untapped graphite riches for slice of critical minerals boom
Tucked among forested slopes and pristine valleys in a corner of northeastern India, young villagers have been busy knocking on doors – hoping to convince sceptical elders that graphite mining would bring much-needed jobs to their distant region.
“The youth in our village migrate to cities for work. What’s better than to have jobs near home?” Gollo Doni, a farmer and secretary of the local youth association, told Climate Home News as he and other members in their 20s discussed the latest meetings between locals and representatives of Oil India Limited (OIL), a state company exploring graphite and vanadium reserves in Arunachal Pradesh.
The mining plans in the state, which is home to more than one-third of India’s graphite reserves and the subject of a sovereignty dispute with China, reflect a push by the Indian government to position itself as a leading producer of battery-grade graphite as the mass rollout of batteries for electric vehicles (EVs) and power storage drives demand for the mineral.
An average electric car contains about 60 kg of graphite anode materials, according to the International Energy Agency, and the graphite supply chain is heavily dominated by China, which produces about 80% of the world’s natural graphite and controls more than 90% of global refining.
As Western countries seek to reduce their dependency on China, India’s reserves of graphite and other minerals vital for the switch to clean energy have caught governments’ attention, with Germany signing a critical minerals partnership agreement in January.
Ambitious plans
But hurdles remain to India’s ambitious plans to ramp up critical minerals output, both to position itself as an alternative to China and to meet its own fast-growing needs.
India has a target for 30% of new vehicle sales to be electric by 2030, and demand for EV lithium batteries looks set to surge close to 35-fold between 2023 and 2035, according to S&P Global Mobility, driven by growth in two- and three-wheelers in the country of 1.4 billion people.
Although domestic manufacturing of EV batteries is expanding, the sector remains at an early stage and India depends heavily on imports from China, South Korea and Japan.

At the same time, it wants to get graphite processing off the ground, aiming to turn its reserves of the mineral – which rank among the world’s 10 biggest – into higher value battery-grade supplies.
The energy transition has a rare earth problem: These startups are solving it
With exploration already underway, the next step should be starting discussions about developing processing facilities – including support from foreign partners, said Kaira Rakheja, South Asia energy analyst at the Institute for Energy Economics and Financial Analysis (IEEFA).
“These exploration and extraction projects have a long gestation period. So even if discussions on processing start now, it will still take a while,” she said, noting India’s simultaneous push to create “rare earth corridors” encompassing every step of production.
Hurdles ahead
India’s graphite reserves are mainly of a lower grade, however, making processing for use in battery anodes more complex, while the country is a late entrant.
“We are not a big player in the market and have missed the bus,” said Aditya Ramji, director of the Global South Clean Transportation Centre at the University of California, Davis.
While exploration work is already underway at several sites in Arunachal Pradesh, and at some places in eastern and southern India, production will take at least two years to start, said Tana Tage, director at the Centre for the Earth Sciences and Himalayan Studies, OIL’s local partner and holder of a 10% stake in the Phop project.


A mine would create about 300 jobs and the project’s partners are discussing options for processing the site’s medium- to high-grade graphite locally, Tage added, despite voicing concern about a lack of technological know-how.
“India does not have the large-scale, advanced processing capabilities to achieve the ultra-high purity levels required for EV batteries and clean technologies,” he told Climate Home News.
Diversification drive
Despite such challenges, industry experts say India could benefit from the push to find sources of battery graphite other than China.
“We can’t beat China in this space, but we can still create a space for ourselves in buying and selling, as everyone is looking for a space to diversify,” said Rishabh Jain, fellow at the Council on Energy, Environment and Water, a New Delhi-based think-tank.
India’s government hopes the bilateral memorandum of understanding (MoU) signed with Germany could help.

As well as pledging cooperation on critical minerals exploration, the declaration envisions the exchange of know-how to add value through processing and recycling, facilitating investment and building the supply chain resilience of both countries. That could include identifying joint research projects and facilitating cooperation between industry players.
“India and Germany will work together to mutually strengthen supply chains in the field of critical minerals,” a spokesperson for the German government’s energy strategy said. “We will encourage companies to build strong ties in terms of knowledge sharing, offtake agreements and investments.”
Germany is already supporting several domestic projects focused on converting graphite into battery anode material – valuable experience that could potentially be shared with India, said Rakheja. In return for shared technical expertise, India offers a strong pool of workforce talent and a big market.
“This way, both partners can look beyond China,” she said.
India sets achievable green electricity and emissions intensity targets
The MoU, which is non-binding, is “a good start”, said Svenja Schöneich, a senior advisor at the NGO Germanwatch, adding that it was thin on details, including on how to add value to India’s critical mineral resources.
“The partnership document should figure out the problem of local value creation. It should also consider that it can’t really skip processing through China,” Schöneich said.
An official at India’s Mining Ministry did not respond to requests for comment.
Trade deals and tax breaks
Beyond the five-year German accord, India has implemented numerous policy measures aimed at securing its own supplies of critical minerals and adding value to its mineral exports, for example by signing favourable trade deals. Last year, India’s graphite was granted zero-duty access to the US, just as the tariffs on Chinese graphite imports climbed to a high 160%.
When the government announced the national budget in February, it included a raft of financial measures aimed at kickstarting a plan to process minerals domestically – the details of which are expected to be announced in the coming months.
They included zero customs duty on critical mineral inputs and enhanced tax deductions for exploration, while the government’s production-linked incentive (PLI) scheme allocated the equivalent of $1.87 billion to build domestic battery cell manufacturing.
Before that can happen, progress on new mining – such as the Arunachal Pradesh graphite projects – is vital, Jain said.
“We are in 2026, and looking to move towards a cleaner world. This is the future,” he said.
The state government in Arunachal Pradesh agrees. It called last year for fast-tracked environmental permitting for graphite projects, new infrastructure around mine sites and reforms to avoid legal disputes that could hold the sector back.

Back in the village of Phop, youth association secretary Doni said that while reluctant residents did not raise an objection to OIL’s preliminary exploration licence, he fears a bigger fight ahead.
Tage said up to 3,000 people could ultimately be displaced if the project proceeds, raising questions about whether economic benefits would outweigh the social and environmental costs.
“It has been difficult to make the elders agree to actual mining,” Doni said, as he and other young villagers sipped on sweet tea in a thatched mountain house. “We are trying to convince our elders that mining will not only bring resources for the nation, but bring us jobs here.”

The loss and damage fund needs far more finance to deliver climate justice
Wamuyu Manyara is country director for Trócaire Malawi and Tarcizio Kalaundi is its climate resilience officer.
This week, the Fund for responding to Loss and Damage (FRLD) faces a significant decision that will determine its ability to address the harms being done by climate change.
Discussions on the Fund’s Resource Mobilisation Strategy must get the scale and accessibility of the Fund right. Failure to do so would risk undermining its role to channel finance to countries experiencing loss and damage, and undermine obligations to climate justice and human rights.
This discussion could not come at a more pressing time. As loss and damage (L&D) continues to escalate globally, and as the world teeters perilously close to the Paris Agreement’s critical 1.5C warming limit, the FRLD also faces the very real danger of running out of funding in 2027.
As Nigeria rails at loss and damage “mirage”, fund boss assures money is coming
Experts calculate that in 2025, L&D finance needs for climate-vulnerable countries may have reached USD$937 billion. Last year’s major impacts included a series of extremely destructive cyclones that hit the Philippines, estimated to have caused over $5 billion in losses, while in Jamaica, the losses and damage caused by Hurricane Melissa were estimated at $12.2 billion.
The bill for just one of these disasters would exhaust the Fund’s existing resources many times over. While the costs and human rights violations rack up, almost four years after being agreed at COP27, the FRLD remains critically underfunded.
Pledges to the Fund ($822 million) are just a fraction of 1% of annual loss and damage needs, and only around half of those pledges ($448 million) have been paid into the Fund so far.
Meanwhile, those who have done nothing to cause the climate crisis are facing its worst – and intensifying – impacts and are being left to foot the bill for the damages already incurred, not to mention the severe non-economic costs to communities. It is therefore crucial that the FRLD’s Resource Mobilisation Strategy urgently brings in far more L&D finance.
Contributor conundrum
Many developed states will claim that additional countries should provide L&D finance. This, however, is a distraction – particularly considering the deep abyss between the contributions of developed states that are obligated to pay and their fair share as calculated according to their wealth and historical emissions. Furthermore, some states and regions that are currently not obligated to contribute are already doing so.
Analysis reveals that, even in the highly inequitable scenario where all states including those who have contributed nothing to causing the climate crisis were to pay towards L&D finance, wealthy countries would still be responsible for the vast majority of L&D finance.
The Fund’s Resource Mobilisation Strategy must focus political discussions on the ability of rich and highly polluting states to raise public, grant-based L&D finance that is new and additional to existing climate finance obligations and overseas development assistance.
Developed states have the means to pay and the FRLD should introduce mandatory and progressive mechanisms to make the biggest polluters, including the ultra-rich and fossil fuel corporations, pay for their climate harms.
African impacts
Increasingly unpredictable seasons and more frequent and extreme events are driving food insecurity, malnutrition, displacement and other human rights risks in climate-vulnerable countries, and communities facing these escalating and compounding impacts must be centred in FRLD policies.
In Ethiopia, 2023 saw 24 million people affected by five back-to-back failed rains leading to severe food and water shortages, including a 90% crop loss in drought-affected areas. Eleven million people required food assistance, and over 500,000 people were displaced. Meanwhile, the 2023–24 floods and the 2024 Gofa landslide disrupted or destroyed health facilities, displaced thousands, and led to outbreaks of cholera, malaria, and measles.
Comment: Let’s tax luxury air travel to fund climate adaptation and loss and damage
Today, Somalia is facing one of its most severe drought emergencies in recent history driven by climate extremes. Malnutrition rates continue to exceed projections and previous devastating records, with 1.9 million children in Somalia acutely malnourished.
In Malawi, child stunting had significantly reduced, but climate impacts are now affecting children’s growth and development. Tropical Cyclone Freddy in 2023 was one of the worst on record, causing over 1,200 deaths, displacing half a million people, and causing damages exceeding $500 million. Recovery needs for four major disasters between 2015 and 2023 are estimated at $1.7 billion, equivalent to more than a quarter of Malawi’s 2026-2027 budget.
Funding for communities
Access to community grants in the southern African country, however, has catalysed local responses to L&D that coordinate around immediate and long-term needs and restoring livelihoods.
Direct access to the FRLD for climate-vulnerable countries and communities, with community-centric planning, is essential to ensure that the Fund can respond to the needs of people experiencing the worst impacts of climate change, through prompt and flexible mechanisms that do not hinder recovery options.
Stepping up to fill the FRLD through an ambitious and needs-based Resource Mobilisation Strategy is the bare minimum that wealthy states can and must do. It is, after all, an obligation that flows from the international duties of cooperation and prevention of harm, and from the obligation to provide reparation when harm occurs. Failure to do so would further erode climate justice and human rights for communities on the frontline of loss and damage.
