Key developments
Clean-energy industry drives China growth in 2023
CLEANTECH BOOM: New analysis for Carbon Brief found that clean-energy sectors – spanning low-carbon power, grids, energy storage, electric vehicles (EVs) and railways – contributed 11.4tn yuan ($1.6tn) to China’s economy in 2023, accounting for “all of the growth in Chinese investment and a larger share of economic growth than any other part of the economy”. This was driven, in particular, by the “new three” industries of solar power, EVs and batteries. Investment totalled 6.3tn yuan ($890bn), growing 40% year-on-year and almost equalling all global investments in fossil fuel supply last year – or the entire economies of Switzerland or Turkey.
GDP BOOST: Clean-energy sectors accounted for 40% of the expansion of GDP in 2023, the analysis showed. Without this contribution, China’s GDP would have risen only by 3% instead of 5.2% – well below the growth target set for 2023. This makes the industry not only crucial for China’s energy transition, but also for “broader economic and industrial” development, found the analysis.
OVERCAPACITY CONCERNS: However, the analysis continued, “the spectre of overcapacity means China’s clean-energy investment growth…cannot continue indefinitely”, adding that “the manufacturing expansion has already saturated most of the global market”. In related news, Jiemian reported exports of the “new three” industries reached more than 1tn yuan ($141bn). This has seen the EU, among others, take steps to support their own clean-energy industries, reported Agence France-Presse, adding that Chinese premier Li Qiang recently held “frank” talks with European Commission president Ursula von der Leyen on trade imbalances.
China relaunched voluntary carbon market
RESUMED TRADING: State-run broadcaster CCTV reported that China’s voluntary carbon-trading system, the China Certified Emission Reduction (CCER) programme, resumed trading on 22 January. CCER’s relaunch “marks the completion of China’s domestic carbon-market architecture”, the broadcaster added. Beijing News described CCER as an “institutional innovation to mobilise the power of the whole society to participate in greenhouse gas emission reduction actions”.
NEW CREDITS?: Economic outlet Jiemian said that CCER project registration was suspended in 2017. It reported that “preparation on the policy end” for restarting issuance of carbon credits under the scheme is “almost complete”, pending the “state administration for market regulation (SAMR)…releas[ing] the list of recognised validation and verification institutions”. The scale of new CCER issuance is predicted to be between tens of millions to 100m tonnes per year, according to one analyst, the newspaper adds.
INCLUDED SCOPE: Finance news outlet EastMoney reported that the greenhouse gas trading under the scheme is primarily open to enterprises or institutions in four major sectors: “afforestation carbon sinks, grid-connected solar-thermal power generation, grid-connected offshore wind power generation and mangrove plantation”. It may in future allow individuals “to sell carbon emissions generated from green behaviours under the CCER scheme…as the trading mechanism matures”, according to the South China Morning Post.
Tasks, measures and timelines for ‘Beautiful China’
BEAUTIFUL CHINA: The top bodies of the Chinese government and governing Communist party – the state council and the central committee, respectively – issued the full text of new instructions on “comprehensively promoting the construction of a Beautiful China” in a 27 December official release, published by state news agency Xinhua on 11 January. The Beautiful China initiative is a “top-level development blueprint detailing specific targets for…the nation’s green and high-quality growth”, another Xinhua report explained. ClientEarth’s Dimitri De Boer wrote in China Dialogue that the initiative “ties a good environment to a sense of national pride”.
KEY GOALS: The document outlined a slew of tasks, measures and timelines within China’s overall push to peak its carbon emissions before 2030 and reach carbon neutrality by 2060. By 2027, “green and low-carbon development” will be “further promoted”, it said. By 2035, “green production methods and lifestyles will be widely formed”. By the middle of the century, “ecological civilisation will be comprehensively upgraded…[with] deep decarbonisation achieved in key areas”. Goals listed in the document include: the country will compile an annual national greenhouse gas inventory; “gradually shift” to “dual control” of carbon emissions; protect more than 3.15m square kilometres of land from being eligible for development projects under the national ecological “red line” policy; ensure China’s cities become “waste-free” by 2035; and see new energy vehicles (NEVs, mostly electric vehicles) comprise around 45% of new cars by 2027.
OFFICIAL COMMENT: The document was passed in a meeting chaired by Chinese president Xi Jinping, who said that “building a Beautiful China is an important goal for building a modern socialist country”, the state-run China Daily reported – giving the document more weight and signalling to officials that China’s carbon-neutrality goals remain an important target. Adding to the momentum, following its publication, Sun Jinlong and Huang Runqiu – the Communist party secretary and the minister at the ministry of ecology and environment (MEE), respectively – wrote an opinion piece in the Communist party-backed newspaper People’s Daily saying that the document “clearly defines the overall requirements, key tasks and major initiatives” guiding the Beautiful China initiative. In an interview with Xinhua, a senior official of the MEE said incentives and policy measures could “mobilise enthusiasm, initiative and creativity” to build a Beautiful China.
US and China climate envoys step down
KERRY RETIRES: US climate envoy John Kerry plans to retire from his role in the next few months, in order “to help President Biden’s [re-election] campaign”, Axios reported. In stepping back from “a major diplomatic role that was created especially for him”, the New York Times reported, Kerry casts the position into “an uncertain future”. The fact that he has chosen to do so following the retirement of Chinese climate envoy Xie Zhenhua “[raises] concerns about what climate diplomacy will look [like]” without their cooperative personal dynamic, it added.
END OF AN ERA: Xie and Kerry “have a close personal relationship”, Climate Home News reported, adding that “Xie’s return from retirement in 2021 was widely interpreted as a response to Kerry’s appointment [to the climate envoy role]”. “If Kerry and Xie weren’t in office…there’s no way we’d be even close to where we’re at,” the Financial Times quoted Jake Schmidt, a senior director at thinktank NRDC, saying. It also reported that Kerry said he and Xie were “doing all we can to stay in very close touch; and he and I will continue to work in respective institutions [to forge collaboration on climate change]”.
NEW BLOOD: Career diplomat Liu Zhenmin – profiled in Carbon Brief’s DeBriefed newsletter – will become China’s new climate envoy, Reuters reported. The newswire added that Liu has “long experience in climate diplomacy”, participating in both the Kyoto Protocol and Paris Agreement negotiations. Liu “was a key driver in landing the Kyoto Protocol”, Greenpeace East Asia chief China representative Yuan Ying told Carbon Brief, which is “a promising piece of experience”. However, Climate Home News quoted an anonymous analyst as saying “many experts wanted someone from the environment ministry appointed”, as “[the foreign ministry] approaches climate as a card in US-China [manoeuvring]” instead of seeing it “as a real issue that needs to be solved”.
Spotlight
Interview with Prof Zou Ji, CEO and president of the Energy Foundation China
At COP28, Carbon Brief sat down with Prof Zou Ji, CEO and president of the Energy Foundation China, to discuss China’s energy transition.
Prof Zou previously served as a deputy director-general of China’s National Center for Climate Change Strategy and International Cooperation.
He was part of China’s negotiation team for the Paris Agreement and a lead author of several Intergovernmental Panel on Climate Change assessment reports.
Below are highlights from the wide-ranging conversation, covering China’s stance on coal, renewables, issues-based alliances and more. The full interview will be published on the Carbon Brief website soon.
China’s decisions at COP28
On signing pledges at COP: “If you look at the whole history of the COP…I do not [remember] China joining any alliances. I have never seen that…As a party, China [is only concerned with] official procedures, waiting for a legal framework of the UNFCCC or the Paris Agreement.”
On why China did not join the pledge to triple renewables and double efficiency: “[Before COP28] we have not seen [it laid out] very clearly which year should be the base year [from which tripling renewables should be calculated]. Should it be 2020? Should it be 2022? This might seem to be technical but, [in] the past two years, global development of renewables, especially in China, [have been significantly boosted, and so]…the difference in targets might be very significant.”
On China’s commitment to decarbonisation: “If you look back at history, there have been very few cases that show China [first making] and then [giving up] a commitment. This is not the political culture in China.”
The future of coal
On fossil fuel phaseout: “I would like to see…[China] very quickly enlarging its renewable capacity. Only if [there is] adequate capacity and generation of renewables can this lead to a real phasing out or phasing down of fossil fuels.”
On others’ views of required coal capacity: “Even though China will reach its [2060] carbon neutrality target, it will continue to have to maintain 600 gigawatts of coal-fired power plant capacity. These are the sort of estimations [we’re working with now].” (Prof Zou disagrees with this, believing that renewables growth, better grid connectivity and increased energy storage capacity should reduce the need for such a large amount of coal capacity.)
On the need for CCUS: “In some sectors, like, for example, iron and steel, cement, chemicals and petrochemicals, we do need carbon capture, utilisation and storage (CCUS), because it is very difficult to phase out coal or carbon dioxide [completely].”
On CCUS in the power sector: “I have mixed feelings about CCUS for the power sector. I have an ideal vision that we can reach real zero emissions in these sectors through a more developed grid system, with more connectivity across provinces or regions and the use of AI technology.”
Transitioning to renewable energy
On ensuring more renewables uptake: “We have raised the share of renewable power generation from seven, eight, nine per cent to today’s 16%. This is progress, but it is not quick enough or large enough. We want to push the grid companies…to do more and do it faster.”
On the power of distributed solar: “We should also consider…creat[ing] another, totally new power system. This would be a sort of nexus of a centralised and decentralised grid system…If [the central grid] is having difficulties [increasing renewable generation], and if these are very challenging to overcome, then let’s [shift] to a lot of microgrids.”
On distributed solar growth: “Today, the share of distributed [renewables] is still lower than centralised renewables. But the incremental [distributed] renewables growth has become higher than growth of centralised renewables in the past year or two, and I would assume this will remain a trend in the future.”
Measuring energy use
On China’s electricity consumption: “For low-income level groups, although their income has not grown very much, their consumption preferences and mindsets – especially for younger generations of consumers – mean they are more willing to use electricity [than previous generations].”
On comparisons of China to the EU and US: “There is a structural [difference] compared to the [energy mix] in Europe and the US. The majority of energy use [in China] has been for industrial production, rather than for residential [use]…In China, the average power consumption per capita is around 6,000 kilowatt-hours (kWh), compared to 8,000kWh in Europe and over 12,000kWh in the US.”
On energy efficiency: “Physically, I think China has become better and better [in terms of] its efficiency, but, economically, this cannot produce as high a value-add as Europe and the US in monetary terms.”
On challenges calculating carbon intensity: “The raising of interest rates by the US Federal Reserve makes US dollars more expensive, increasing foreign exchange rates which then enlarges the monetary GDP gap making Chinese GDP [in dollar terms] fall, and carbon intensity rise.”
Watch, read, listen
FOSSIL FUEL HIGHS: Clyde Russell, Asia commodities and energy columnist at Reuters, wrote that, although China’s crude oil and coal imports “all soared to record highs in 2023”, crude oil is likely being added to inventories rather than being used, while the spike in coal is a temporary response to hydropower shortages.
ROSEWOOD DEFORESTATION: The China-Global South Project spoke to Ma Haibing, Asia policy specialist at the Environmental Investigation Agency, about illegal harvesting of rosewood by Chinese traders in the “rapidly shrinking forests” of west Africa.
GREEN SHOOTS: Yicai interviewed Zhang Xiaoqiang, executive vice-president of the China Center for International Economic Exchanges (CCIEE), on prospects for “green” development in China in 2024, the growth of renewables, cross-provincial power transmission and other topics.
ANTARCTIC RESEARCH: CCTV broadcasted a short news report on the progress of the 40th Chinese Antarctic research expedition in building China’s newest research station in Antarctica.
New science
Drought-related wildfire accounts for one-third of the forest wildfires in subtropical China
Agricultural and Forest Meteorology
A new study found that “drought plays a dominant role” in wildfires in subtropical China, adding that “from 2001 to 2020, excess wildfires caused by drought accounted for approximately 31% of the total number of forest fire points during the fire season (November to May)”. As the drying trend caused by climate change intensifies, wildfires will “show different patterns due to the large differences in the sensitivity of wildfire to drought in subtropical China”, it added.
Bulletin of the American Meteorological Society
Human-caused climate change made the August 2022 heatwave in southern China 50% hotter than it would have been without global warming, according to new research. The heatwave, the researchers noted, was “extraordinary and unprecedented”, being the “longest-lasting and most intense [China has seen] since 1961”. The study also found that, although it was focused on southern China, “the main conclusions also apply to the eastern Tibetan plateau”.
Potential for CO2 storage in shale basins in China
International Journal of Greenhouse Gas Control
Researchers used the latest data to calculate new “potentials of [carbon dioxide (CO2)] storage in major shale gas/oil basins in China”, driven by the fact that China, as the second largest shale gas and oil producing country, possesses “large and significant” shale basins. They found that China could sequester approximately 6,194bn tonnes of CO2 in shale basins, equivalent to 620 years’ of China’s projected carbon emissions.

The planet is heating up more quickly than ever before.
For decades, greenhouse gas emissions caused by human activity have been building up in the atmosphere and trapping ever-higher levels of heat.
The resulting asymmetry between incoming solar energy and energy radiated back out into space – known as “Earth’s energy imbalance” – provides a direct measure of the extent to which humans are disrupting the Earth’s climate system.
This imbalance is growing and in 2025 its 10-year average reached a record high, indicating that global temperatures could increase at even higher rates in the future.
This is among the headline findings of the latest “indicators of global climate change” (IGCC) report, published in the journal Earth System Science Data, which tracks changes in the climate system on an annual basis.
The report, now in its fourth iteration, has been produced by dozens of scientists from around the world.
Its findings are designed to fill the gap between Intergovernmental Panel on Climate Change (IPCC) science reports, which are published every 5-7 years.
In this article, we unpack the IGCC report, which explores how human activity is driving a growing energy imbalance and why monitoring systems to track global climate are so crucial.
(For more on previous IGCC reports, see Carbon Brief’s coverage in 2023, 2024 and 2025.)
Greenhouse gas emissions remain at an all-time high
Global greenhouse gas emissions are continuing to increase, mostly as a result of the use of fossil fuels. However, deforestation, agriculture and industrial processes also play an important role.
Over the most recent decade (2015-24), emissions stood at the equivalent of 54.6bn tonnes of carbon dioxide equivalent (GtCO2e) per year. In 2024, the most recent year for which we have complete data, emissions reached 56.8GtCO2e.
As the chart below shows, these emissions have pushed up atmospheric levels of CO2, methane and nitrous oxide. In 2025, concentrations of these gases reached 425.6 parts per million (ppm), 1936.3 parts per billion (ppb) and 339.4ppb, respectively.
This represents a rise of 3.8%, 3.8% and 2.2%, respectively, since the 2019 levels reported in the IPCC’s sixth assessment report (AR6).
At the same time, declines in emissions of aerosols such as sulphur dioxide, partly as a result of efforts to tackle air pollution, are increasing the Earth’s energy imbalance. This is because aerosols have a cooling effect on the Earth’s climate, counteracting warming from CO2 and other greenhouse gas emissions.
(Tackling sulphur dioxide, alongside other particulate emissions, remains critical because the immediate health and environmental damage they cause far outweighs their short-term cooling effect on the climate.)
The Earth’s energy imbalance is rising rapidly
The Earth’s energy imbalance has long been recognised as a key indicator of how the climate is being affected by human activities.
However, it is only in the last few decades that scientists have been able to record temperature changes deep enough in the ocean to accurately quantify it.
Earth’s energy imbalance measures how quickly excess heat is accumulating in every part of the Earth system, primarily in the ocean, but also in land, ice and atmosphere.
Through this accumulation of heat, the energy imbalance influences the rate of sea level rise and ice melt across the world, as well as increasing the frequency and intensity of extreme weather events, such as storms, floods and droughts.
Without human influence, the Earth’s energy imbalance would be close to zero.
But, as greenhouse gas emissions have built up in the atmosphere, the imbalance has been growing since the 1970s. Recent increases to Earth’s energy imbalance have outpaced those projections made by climate models — indicating the planet could see more warming than expected in the future.
As the right-hand chart below shows, the imbalance is now at a record high, having more than doubled over the past two decades.
It has increased by around 40% since 2019, from an average 0.79 watts per square metre (Wm2) over 2006-18, according to IPCC AR6, to 1.12Wm2 over 2013-25.
The left-hand chart shows how heat is accumulating in the ocean (blues), ice (grey), land (orange) and atmosphere (purple).
Global temperature rise
The excess heat building up in the climate system from the energy imbalance is pushing up global temperatures at a record rate of 0.27C per decade.
We estimate that human-induced warming – the amount of observed global surface
temperature increase attributable to both the direct and indirect effects of human activities – reached 1.37C in 2025. This has risen from 1.0C in 2017, as reported in IPCC AR6.
While natural variability in the climate system – such as El Niño or La Niña events – can also influence temperatures year-to-year, the upward temperature trend we are seeing is being driven by the persistent imbalance in energy.
We now expect global temperatures to exceed the Paris Agreement limit of 1.5C above pre-industrial levels around the year 2030.
This is significant because 1.5C has been identified as the critical dividing line between manageable climate risks and catastrophic, potentially irreversible damage to global ecosystems and human societies.
Heat accumulating throughout the Earth system
While heat is accumulating throughout the Earth system, it is not being distributed evenly around the globe.
Since the 1970s, around 90% of this heat has been taken up by the ocean, affecting marine ecosystems, ocean circulation patterns, sea level rise and climate extremes.
For example, the number of marine heatwave days – periods of unusually high sea surface temperatures – has more than tripled globally since the early 1990s. The year 2025 alone saw 65 days of marine heatwaves – meaning they occurred, on average, more than one day a week.
Meanwhile, the cryosphere – the portion of the Earth made up of frozen water, including glaciers, ice sheets and permafrost – is experiencing widespread ice loss and thawing in response to the growing energy imbalance. This affects ecosystems, sea level rise and infrastructure in polar and high-latitude regions.
Rapid warming has also resulted in record extreme temperatures over land, with average maximum temperatures for any single day over 2016-25 around 1.92C above pre-industrial levels). This is an increase of almost half a degree compared to the previous decade (2006-15).
Sea level rise and the energy imbalance
Sea level rise provides one of the clearest long-term signals of a changing planet.
It is closely linked to Earth’s energy imbalance. As heat accumulates in the ocean, water expands, raising sea levels. Meanwhile, a warming land and atmosphere means addition of water to the oceans through melting of glaciers and ice sheets, also adding to sea level rise.
Over the long-term, sea levels have been rising, on average, at a rate of around 1.8mm per year since 1901, totalling a record 23cm in 2025. This is increasing the risk of coastal flooding, erosion and habitat loss in many low-lying areas around the world.
This rise can be seen in the left-hand chart below, which shows observed global sea level changes from tide gauges (grey and blue dashed lines) and satellites (red dashed lines) since 1901. The solid lines indicate the average across multiple datasets.
Sea level rise is accelerating consistent with the observed increase in Earth’s energy imbalance. Over 2006-25, sea levels have risen at a rate of 3.67mm per year – more than double the rate of 1.69mm per year seen over 1976-95.
This increasing rate is shown in the right-hand figure below, which shows four successive overlapping 20-year periods and the most-recent decade.
(Last year’s transition from El Niño to weak La Niña conditions affected global rainfall patterns and led to a small and temporary fall in global average sea level in 2025. This explains the slight decrease in rate of sea level rise for the most recent decade, which is affected more than the 20-year period 2006-25.)
The bigger picture
Despite greenhouse gas emissions not increasing as rapidly as in the 2000s, this year’s IGCC findings continue to show how far and how fast the climate is changing due to human activity.
A significant increase in decarbonisation efforts in the second half of this decade is required to slow down the rate of human-caused warming and limit the escalation of climate risks and impacts.
These findings, like many others produced by scientists across the globe, rely on international expertise, partnership and the maintenance and availability of global climate datasets and the global observing programmes that underpin them.
This year’s edition of IGCC used more than 40 global datasets produced by research teams around the world, including the NASA satellite record of the Earth’s energy imbalance and the ARGO deep ocean float network.
However, a number of long-term monitoring programmes could be threatened by funding decisions made by governments around the world, most notably the Trump administration in the US.
Local meteorological data and weather balloon measurement programmes in many countries have declined in recent years, especially in Africa, the west Pacific and South America. This reduces scientists’ ability to monitor and understand key indicators of climate change.
This is not just an issue for climate science. Many of these observations are key to weather forecasts and systems that provide early warning for extreme weather. For example, media reports have suggested that recent reductions in weather balloon measurements in Alaska led to a lack of warnings for a recent winter storm.
The continuity and integrity of the climate observations that scientists use to understand how the climate is changing depends on effective and sustained coordination by international organisations, such as the Global Climate Observing System, the World Meteorological Organization and World Climate Research Programme.
Without this data and its coordination, future assessments will be much more difficult at a time when urgent climate action is needed.
