Key developments
March data indicates carbon emissions peak
SURGE ENDED: Carbon dioxide (CO2) emissions in China fell 3% in March 2024, ending a 14-month surge and possibly signalling that Chinese CO2 emissions peaked in 2023, according to new analysis for Carbon Brief by Lauri Myllyvirta. The fall was driven by the record growth of solar and wind power generation, which “covered 90% of the growth in electricity demand”, and by declining construction activity. An increasing portion of electricity demand is being covered by distributed solar, which comprised 45% of last year’s solar capacity additions. Meanwhile, limited demand for steel and cement due to continued uncertainty in the real-estate sector saw a drop in emissions of 30 megatonnes of CO2 (MTCO2) from the construction sector.

AMBITION GAP: Maintaining the record rate of clean energy installations could make a 2023 peak in CO2 emissions “possible” for China, the analysis added, as the “main driver of China’s emissions growth in recent years has been the power sector”, which has only grown 1% year-on-year. The article noted, however, that industry associations, such as China Photovoltaic Industry Association (CPIA), expect solar and wind capacity additions by 2030 to significantly exceed official targets. The analysis found the difference amounts to 1,400-1,800 gigawatts (GW), which – if the resulting clean power generation from more ambitious forecasts were to replace coal – could see a difference in CO2 emissions amounting to 10-15% of China’s current emissions. China “is already severely off track” to meet its carbon-intensity target, the analysis added. Its ability to meet this target, which is part of its international climate pledge under the Paris Agreement, “depends on clean energy growth continuing to significantly exceed the central government’s targets – or those targets being ratcheted up”, said the analysis, which was picked up by the New York Times, Reuters, Bloomberg, AFP and Straits Times, among others.
NEW ACTION PLAN: China’s state council released a new action plan for energy conservation and carbon reduction for 2024 and 2025, which pledges to reduce CO2 emissions by 130m tonnes by 2025 through reforming the “nonferrous metal industry”, according to state news agency Xinhua. Reuters also covered the story, stating that the targeted reductions in CO2 emissions is “equivalent to about 1% of the 2023 national total”.
China rebuts G7 trade accusations
G7 MEETINGS: The G7 countries’ finance ministers and central bank governors have raised a “unified voice to counter some of the concerns they had over China’s trade policies” at their meetings in Italy on 23-25 May, according to Bloomberg. The ministers plan to “continue to monitor the potential negative impacts of overcapacity and will consider taking steps to ensure a level playing field,” another Bloomberg article said. Ahead of the meeting, Reuters and Bloomberg covered comments by US treasury secretary Janet Yellen, who called for “market-driven countries” to “stand together” to counter China’s “state-driven” industrial policies, which she viewed as a “threat” to the “viability of firms around the world, including in emerging markets”. EU president Ursula von der Leyen told the Financial Times, also ahead of the G7 meeting, that she shared concerns over overcapacity, but “we want to signal it’s not about closing the market or protectionism…We want to de-risk, not decouple [from China]. And now we’re developing the toolbox.”
CHINA’S RESPONSE: China’s foreign ministry rejected the “unilateral” G7 accusation, calling it a “discriminatory practice”, reported state broadcaster CGTN. The ministry’s spokesperson, Mao Ning, said at a press conference: “The G7’s ‘Chinese overcapacity’ hype and attempt to restrict China’s new energy products are completely against the facts and the laws of economics. They are the product of protectionism and serve no one’s interest.” Separately, China “has signalled it will retaliate” to EU anti-dumping concerns, with the Ministry of Commerce announcing plans to probe imports from the EU, US and other regions of a widely used thermoplastic, according to the Financial Times. Meanwhile, the China Chamber of Commerce to the EU said on Twitter it was informed about a potential up to 25% tariff from China on vehicles with large engines, as “Beijing is ramping up threats of retaliation as a deadline looms for the EU to announce results of its probe into China’s electric-vehicle subsidies”, Bloomberg reported.
Solar sector struggles to ‘control capacity’
PRICING WOES: Chinese financial news outlet Yicai reported that, according to the China Nonferrous Metals Industry Association, “the price of high-purity polycrystalline silicon, the raw material used to make solar panels, has plunged below cost for all producers in China”. The situation “has forced some suppliers to halt production” and means that “even big players…which should have better cost controls than smaller firms, could be losing money at the moment”. Shortly afterwards, in an announcement covered by the South China Morning Post (SCMP), the CPIA called for “more mergers, acquisitions and curbs on domestic competition to control capacity” in the solar sector, following a meeting held to address falling prices and “operational pressures”.
XI ON OVERCAPACITY: According to SCMP, Chinese president Xi Jinping, in a meeting with prominent business figures and economists, said that support for the “new three” types (solar products, lithium-ion batteries and electric vehicles) must be “adapted” to local conditions, adding that the new energy industry should not be the sole focus of economic growth. A separate analysis by SCMP said China’s “overcapacity conundrum” is rooted in the economic reforms that began with its transition to a market-based economy in 1978. “Local governments have played an outsized role” in developing industrial overcapacity, it said, “prominent industry insiders have also publicly spoken on how insufficient downstream demand became a worrisome issue among authorities at city and provincial levels”.

Interview: China’s position on ‘international climate finance’ ahead of COP29
China’s stance on “international climate finance” – a UN-promoted mechanism designed to get developed countries to help fund developing countries address climate change – remains controversial. The country did not make a pledge to the “loss-and-damage fund” established at COP28, but has provided alternative climate funding through its South-South Climate Cooperation Fund and the Belt and Road Initiative (BRI).
Ahead of next week’s Bonn conference – where delegates are expected to negotiate climate finance – Carbon Brief has interviewed Li Shuo, head of the China climate hub at the Asia Society Policy Institute (ASPI), on China’s attitude towards contributing and its potential position at the upcoming COP29.
Below are highlights from the conversation. The full interview can be found on the Carbon Brief website.
Carbon Brief: At the COP29 climate talks [in November], countries will be negotiating a new climate finance target. China is facing growing calls to start contributing. How is it responding to this?
Li Shuo: I think we are expecting a pretty heated debate at COP29. This is indeed one of the most controversial issues…that sees very strong division between the global south and the global north. And, of course, China is in this unique position: it is still firmly in the developing country camp, but, at the same time, it has become one of the largest economies and the largest emitters in the world. So with that, you know, there’s this argument that China should shoulder more responsibility internationally, including by providing future climate finance.
The geopolitical environment is definitely not helping that transition…In addition to that, China’s domestic political and economic situation – let’s just say, it’s not at a particularly helpful moment for that transition to happen…So we see a lot of risk factors. There is a critical need for other countries and China…to align ahead of COP29.
CB: Some might argue that China is providing affordable, clean energy technology and shouldn’t be pressured to scale up climate finance. Could this be one of the arguments made at COP29?
LS: Well, I actually hope this could be one solution to the $100bn – or $1tn – NCQG [new collective quantified goal] question. I actually genuinely see that it could be a solution based on which we can find a path forward.
…The reason I say this is…in addition to China’s emission portfolio, the country also happens to be the biggest solution provider when it comes to low-carbon products. Of course, there are increasing political controversies around China’s position in this regard, in particular between the US and China. But, I think, if you were China, what you want to achieve is, of course, to make sure that you can continue to sell those low-carbon solutions to the rest of the world.
So I would argue it actually works in China’s self-interest to make sure that they can facilitate the deployment of renewable energy in the global south. And, that way, I think it helps address the geopolitical problem, the so-called overcapacity [problem]…If China can play a role in this regard, at the bare minimum, it is helping its own companies.
CB: Do you think that that would be politically viable?
LS: …I doubt the NCQG will ever be as explicit as China committing to support developing countries to buy China-made products…The decision will be made in more general terms; general enough to not agitate the US and the EU. In my mind, of course the NCQG discussion is still an ongoing one, but you might be familiar with this “onion” [structure] approach, a kind of multi-layer package. You have a core: public international finance. The controversial issue there is you will have a number, but who will be accountable for that number?…Then the second [layer] might be some sort of investment facilitation…that’s where I think China can play a role.
CB: How do you think that requests for China to contribute to climate finance could be more successful?
LS: When you talk about UNFCCC climate finance, it is an intrinsically more political debate. The core of the question is: how does China see itself in relation to the rest of the world, and in relation to other traditional donor developed countries…I think, going forward, messages that are crafted in a more inviting way will probably work better with China. But…the political environment that we have will almost prevent that conversation from happening.
CB: Could you explain what you mean by “inviting”?
LS: If your framing is ‘China needs to pay’, or ‘we believe China is ready’ or ‘China is responsible’, then I think politically this will become very difficult for China. Because a lot of the framing – even just enlarging the donor base, that phrase – if you think about it, it assumes kind of a moral high ground…Enlarging the donor base also carries this undertone that “we want more people to pay so that we can pay less”…We do believe there could be areas where China and other traditional donor countries can complement each other. They need to work out the specific areas where they share synergy.

Widespread societal and ecological impacts from projected Tibetan Plateau lake expansion
Nature Geoscience
By the end of the century, the surface area of lakes on the Tibetan Plateau will increase by over 50% (around 20,000km2) and water levels will rise by around 10 metres, even under a low emissions scenario, according to new research. It added that, if no adaptation measures are introduced, this lake expansion will submerge more than 1,000km of roads, around 500 settlements and around 10,000km2 of land such as grasslands, wetlands and croplands.
Researchers found that the greenhouse gas emission from the food system in China – the world’s largest producer and consumer of food – accounted for 37% of the country’s total emissions in 2020, based on an assessment of meals eaten in restaurants across the provincial capitals. The study estimated the greenhouse gas emissions of 540 dishes from 36 cuisines and then designed various dietary change strategies to explicitly link food emissions to the Paris Agreement pledges. It concluded that “transitioning towards low-emission cuisines and dishes” could reduce emissions by 38-69%.

Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”
