The Academy of Macroeconomic Research (AMR) is a research institution under the direct supervision of China’s National Development and Reform Commission (NDRC), the ministry in charge of economic development and planning.

As a “national high-end thinktank”, the AMR’s Energy Research Institute is a well-respected body conducting energy transition research and providing vital suggestions on the energy transition to Beijing. 

At this year’s COP29 in Baku, it launched the executive summary of 2024 China Energy Transformation Outlook (CETO), a key report describing China’s pathways to net-zero.

The launch was attended by a number of high-level officials, including climate envoy Liu Zhenmin and the head of the International Energy Agency, Dr Fatih Birol.

Carbon Brief’s Wanyuan Song was granted a rare – and lengthy – joint interview with its director general, Prof Lyu Wenbin, and director, Prof Bai Quan, who is also the lead author of the report, to hear their views about China’s energy transition.

  • On China’s commitment to climate action: “Climate change doesn’t just affect China, it affects every country in the world…Climate change is not fake. It is happening and we are all on the same boat.”
  • On international collaboration: “The joint work [on energy transition pathways] was meant to allow for a deeper grasp of the problems, making the research findings more scientific and [suggestions] more reasonable.”
  • On an early emissions peak: “[W]e would love to try our best…but we can’t rule out all possibilities to peak even earlier than planned.”
  • On updates in this year’s outlook: [This year w]e have also placed more emphasis on international cooperation.”
  • On the need for global cooperation: “To achieve the best scenario, China shouldn’t be the only country that puts efforts into energy transition.”
  • On stimulus and carbon reduction: “China’s ‘two new’ (“两新”) policy – large-scale equipment renewals and trade-ins of consumer goods – is one of [the policies]. The first three aspects [of ‘two new’] directly promote carbon reduction.”
  • On managing electricity grids and markets: “China has never faced this kind of challenge before. The demand for electricity is huge, and soaring.”
  • On China’s coal use: “With renewable energy becoming more powerful and energy storage becoming cheaper and more flexible, coal plants can play the role of ‘firefighters’ in the system – used in an electricity crisis whenever it is needed.”
  • On the role of “green hydrogen”: “[I]t is very expensive at the moment…Commercial and technology innovation are needed to reduce costs.”
  • On calls for greater ambition from China: “It can’t be the case that developing countries need to cut more emissions than developed countries – that would break the UN’s principle of ‘common but differentiated responsibilities’.”

CB: Why is China so determined to achieve its energy transition and combat climate change?

Bai Quan: Climate change doesn’t just affect China, it affects every country in the world. No one is excluded from it. China is one of the victims of extreme weather. The horrifying typhoon in Shanghai in recent months has blown windows off of skyscrapers – Shanghai didn’t have that many typhoons in the past. Autumn in Qinghai province [in west China] used to be cool and dry, but now it has become rainy. The weather forecast [once] said there was light rain in Beijing, but the heavy rain in the neighbouring province Hebei drowned people. Summer is getting hotter and winter is getting colder – this is climate change, and no one can survive alone. If Shanghai was drowned, would London be spared, would New York be OK? Climate change is not fake. It is happening and we are all on the same boat. 

Combating climate change is a must, it is one of our core needs, and the primary thing we need to do to secure life and production. Low-carbon issues have been part of China’s policy  for a long time but it wasn’t as big of a focus until President Xi vouched for climate action with the “dual-carbon” goal. The [“dual-carbon” goal] promise to the world is serious and, after President Xi announced it in 2020, it has become a hot topic [in media and among ordinary people]. The energy transition, as a sustainable solution, helps the “dual-carbon” goal to be realised. 

CB: Your institute is working with national and international partners to produce an annual “China energy transformation outlook”. Can you tell me how that collaboration came about and what the aims of the project are?

Lyu Wenbin: The Chinese government has proposed the “dual-carbon” goal, and the energy transition is an important part of this process. Now that a goal has been clearly set, what we should do to deliver it is to choose the best pathway. Our research was conducted along with the Danish Energy Agency and Columbia University. The joint work was meant to allow for a deeper grasp of the problems, making the research findings more scientific and [suggestions] more reasonable. 

CB: We covered your CETO 2023 report, in which you listed three stages of transformation. The first of these phases is the peaking phase, which lasts until 2030. With China rapidly expanding renewable energy this year and hitting its wind and solar capacity targets six years early, do you think China could peak even earlier than planned – “before 2030”?

BQ: There are many uncertainties and changes in the world economy, geopolitics and even military actions at the moment. Uncertainty also exists in climate change. China’s electricity consumption grew faster than expected and we would love to try our best to overcome all the difficulties to meet China’s carbon peaking goal before 2030, but we can’t rule out all possibilities to peak even earlier than planned.

CB: What differences are there in your outlook for China’s energy transition this year, compared to 2023?

BQ: The scenarios are different, although they are basically aligned. We have also placed more emphasis on international cooperation. The report itself has absorbed experiences from different places, such as Denmark’s experience in heating, for modelling, pathway design and other suggestions in the report. We would be very interested in discussing more new ideas and sharing our experience with everyone else.

CB: What would be needed for China to realise the most ambitious energy transition scenario featured in your report?

BQ: To achieve the best scenario, China shouldn’t be the only country that puts efforts into energy transition. China, as a developing country, at the government level and at the individual level, has already done a lot. The energy transition needs global cooperation. More people will realise the urgent need to combat climate change if we all join hands together. Solving some problems, such as commercialising hydrogen, also needs more joint research.

CB: You have previously said China’s energy transition relies on comprehensive policy support for green industry, “effective” investment in the green and low-carbon sector as well as promoting green consumption. Do you see signs of this in government plans for economic stimulus? 

BQ: Yes, many! China’s “two new” (“两新”) policy – large-scale equipment renewals and trade-ins of consumer goods – is one of them. In the document issued by the State Council [China’s central government], there are four aspects: “implementing equipment updates, trade-in of consumer goods, recycling, and improving standards”. 

The first three aspects directly promote carbon reduction. The first one is to service industrial sectors, the second one is to serve the general public, and the third one is for China’s “circular economy”. The last aspect indirectly serves energy saving and carbon reduction goals, by setting standards [for energy usage, emissions and recycling] to prevent people from re-purchasing outdated equipment with low energy efficiency.

In the past, it was difficult to recycle old production equipment, such as large motors. One obstacle is the challenge of acquiring a “first receipt” to be eligible for tax deductions. [Scrapped product sellers often cannot provide the purchase receipt – the “first receipt” – to the resource recycling companies for value-added tax deductions.] The new policy allows an ordinary invoice to be used for pre-tax deduction, solving the problem. This is a very important incentive to meet the 2027 goals [of the “two new” policy]. 

For the ordinary people, the “two new” policy also benefits their daily life. For example, they can receive subsidies for about 10-20% of a new purchase, with up to 2,000 yuan ($276) to trade-in a new fridge. [Trade-in subsidies for home appliances cover fridges, washing machines, televisions, air conditioners and computers.] They can get new energy saving electronics appliances at a very low price.

The “two new” policy documents clearly state the delineation of responsibilities of both the central and local governments, including funding they should provide. [The central government accounts for about 90% of funding and has issued a 300bn yuan ($41bn) bond to support this effort.] China holds regular press conferences stating progress on the “two new” policy, including on the renewal of outdated solar and wind equipment.

Another vital policy is the “guidelines to ramp up green transition of economic, social development” issued by the Central Committee of the Communist Party of China and the State Council. [See Carbon Brief’s China Briefing for more.] That is to say, it’s not just the [state-affiliated] State Council that promotes the “green transformation”, the Central Committee [the leading body of the Communist party] also really values it. There was a green transition policy before, but this new policy is a top-level design of “full green transition” [across every aspect of society]. It is a blueprint of China’s transition in industry, building [construction], transportation, energy and many other areas. Together with the “two new”, which is an implementation document for this top-level design, we now have both a direction and a manual for the energy transition. 

CB: China is attempting to upgrade its electricity grids and markets to manage the variability of wind and solar power. What are the biggest challenges it faces in this area?

BQ: China has never faced this kind of challenge before. The demand for electricity is huge, and soaring. Reforms in the electricity pricing system and grid management are underway, and so are many other reforms. These reforms need to be economical, fair and feasible. Reforms, in general, have less impact on the rich than the poor. In the end, we can’t just ignore energy safety and cut electricity supply, nor ignore the poor being unable to afford it. This is a big challenge for the government to achieve in such a short time, especially if we are to peak carbon before 2030. Current price reform, in terms of whole reform effort, is happening very quickly, with the medium-to-long term contract reforms, as well as the spot market and the ancillary market reforms. However, it is a complicated matter, with each province facing different situations. Industrial usage and civilian usage are also different – we need to protect ordinary people’s needs.

CB: There has been significant international criticism of China’s decision to use coal-fired power plants as “flexibility providers” in its energy transition. Will coal continue to be necessary for China’s energy mix as it approaches carbon neutrality in 2060 and beyond, and how effective are China’s current efforts to develop low-carbon coal-fired power?

BQ: China’s principle is “construction new before destruct old” (先立后破), which is also translated as “build before breaking”. [See Carbon Brief’s articles from 2021 and 2022 for background.] The challenge China faces is different [from other countries], our electricity consumption is growing too fast. Energy security for us is most important, and cutting coal out completely does not match the basic principle of energy supply. What we can do is to increase the share of green electricity when improving the overall quantity and quality of electricity supply. Power grids also need to improve capacity for electricity generated from renewable sources, to counter their variable nature. Energy storage is an ideal solution for us, but it is too expensive at the moment. 

The only pragmatic solution at the moment is asking coal plants to “tiao feng” (调峰, part-load operation, which means run below full-capacity). The old design of a coal-fired power plant was to operate for 5,500 hours annually, but they are at about 4,000 hours now. With renewable energy becoming more powerful and energy storage becoming cheaper and more flexible, coal plants can play the role of “firefighters” in the system – used in an electricity crisis whenever it is needed. 

Overall, electricity is the core of future development. Reforms in electricity generation, power grids, electricity usage and electricity demand are all needed. Developing countries in particular face harder challenges. It is not only China – Vietnam and India also are exploring solutions to their power problems. Therefore, we emphasise global cooperation, which is vital for finding a solution for us all.

CB: Will “green hydrogen” play a significant role in China’s future energy mix and, if so, when do you think it will be deployed at scale?

BQ: Yes. Green hydrogen is a great alternative for fossil fuels in the chemical industry and the transportation sector. We were excited about it when it was first discovered, but it is very expensive at the moment. To deploy green hydrogen, commercial and technology innovation are needed, to reduce costs.

China’s carbon pricing has not reached the chemical industry yet, but it might change with changes in the market. The commercialisation of hydrogen is very important, a hydrogen fuel-cell vehicle needs to be affordable. We face the same problem that the EU faces and we would love to learn from them. 

CB: Recent research has suggested that China should reduce emissions to at least 30% below 2023 levels by 2035, to align with the Paris Agreement goal of limiting warming to 1.5C. Some Chinese scientists have called this 30% figure “too ambitious”. Do you think a 30% reduction would be achievable? 

BQ: I haven’t read the paper so can’t comment on it. I am not sure if there are suggestions for other countries in this research paper. [International expectations for China’s climate goals] need to be fair for China, as a developing country. [They] need to consider the shared responsibilities of the developed countries, including the US and EU. It can’t be the case that developing countries need to cut more emissions than developed countries – that would break the UN’s principle of “common but differentiated responsibilities”. China has not yet reached carbon peak, it still has some ways to go.

Heatwaves driving recent ‘surge’ in compound drought and heat extremes

Published

on

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.”

An essential guide to the week’s key developments relating to climate change.

Energy crisis

ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.

‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.

‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home
