Extreme weather events, such as heavy rainfall, flooding and heatwaves, have been described as the “new normal” for China.
The country lost almost 12bn yuan ($1.65bn) due to heavy rainfall and floods in April – “the worst in 10 years”. In June, dozens of people were killed and some 33 rivers in China “exceeded warning levels”. The floods in Guilin, capital city of Guangxi province, were the largest in the area since 1998.
It has been less than a year since the Beijing meteorological service recorded 745mm of rain in just five days during July 2023 – roughly the same amount the city usually receives in the whole month.
The province surrounding Beijing, Hebei, also had heavy rainfall at the same time. In July 2023, the county of Lincheng recorded more than one metre of rain, twice its annual average.
In July 2021, Hebei’s neighbouring province Henan had a “one-in-a-thousand-year” rainstorm.
While China has issued more policies to improve its emergency response system and infrastructure, the increasing number of extreme weather events continues to pose challenges.

What are the reasons behind the recent floods?
There are various factors behind the frequent heavy rain and flooding in recent years.
Dr Oliver Wing, honorary research fellow at the school of geographical sciences, University of Bristol, tells Carbon Brief that “on the whole, we expect a warming world to be a wetter world due to the Clausius-Clapeyron relationship”.
This relationship dictates that the air can generally hold around 7% more moisture for every 1C of temperature rise, meaning rainfall is likely to be heavier in a warmer climate.
Wing notes that “for sub-daily rainfall, we are seeing even greater scaling than this relationship would suggest. This makes surface water flooding in cities [more likely] due to short-duration, intense, localised rainfall increase”.
In addition, he says, “warming is inducing a rise in sea levels in most places, meaning storm surges have a higher baseline from which to inflict damage”.
In China, “higher than normal temperatures” were behind frequent heavy rainfall in southern coastal provinces, such as Guangdong and Guangxi, since April, says Zheng Zhihai, chief forecaster at the National Climate Centre of the China Meteorological Administration (CMA), and reported in China Daily.
Zheng adds that the El Niño-Southern Oscillation – a natural climate cycle that entered its warmer El Niño phase in mid-2023 – was partly to blame because it raised sea surface temperatures and directed vast amounts of water vapour from the South China Sea and the Bay of Bengal towards southern China.
Dr Faith Chan, head of the school of geographical sciences at the University of Nottingham Ningbo China, tells Carbon Brief that the rainfall pattern in Guangdong during this April was quite similar to the intensive rainstorm on 6-8 September in 2023 after Typhoon Haikui.
Specifically, the intense rainfalls were generated by the low-pressure moist current from the south-east and south Asian monsoon pattern crashing into another low-pressure rain belt from the Philippines and the west Pacific.
Typhoon Haikui had hit Hong Kong with the worst storm in 140 years and caused some of the heaviest rains in the provinces of Guangdong and Fujian.
While these intense rainstorms, in a meteorological sense, are not unusual, they are happening more closely to one another owing to the warming world, Chan says.
Large-scale heavy rainstorms typically occur three times on average in April – the onset of a monsoon season. But, this year, China has been battered by at least eight regional extreme rain events in the month alone, all happening in quick succession.
River floods are commonly seen in the affected regions, such as Chongqing and Hunan. Identifying the causes can be more complicated for river floods in general, says Wing:
“There are many modulating factors. Drier soils in a warming world may enable the land to absorb the increased rainfall, thereby mitigating any flood hazard increase. Many floods are not driven by intense rainfall, but are driven by snowmelt or low-intensity, long-duration rain falling on saturated soils. For this reason, it is not reasonable to extrapolate that increased rainfall in a warming world will lead to increased fluvial flooding.”
Chan says natural reasons “of course” enhanced the wetness, “but human-induced climate change led to the greenhouse effect and caused sea temperature to rise, which caused more storms and low-pressure rain belts. That is a fact”.
Wing agrees that “the thermodynamic impact” of human-led climate change increases the rainfall associated with storms. But, he adds:
“What we do not understand well is how anthropogenic climate change has altered the dynamics of the climate system, and where and how this either compounds or dampens the thermodynamic response.”
What role does human-caused climate change play?
Many studies have found that warmer sea surface temperatures are supercharging high-impact, back-to-back extreme rains.
The sixth assessment report (AR6) from the UN’s Intergovernmental Panel on Climate Change (IPCC) also says that human-induced climate change caused by greenhouse gas emissions contributes to ocean warming and “is likely the main driver of the observed global-scale intensification of heavy precipitation over land regions”.
In east and central Asia, under 1.5C of global warming, extreme annual daily rainfall (Rx1) and five-day accumulated rainfall (Rx5) events are projected to increase by 28% and 15%, respectively, relative to 1971-2000, according to AR6.
Similarly, it says that in China’s urban agglomerations, “an increase in global warming from 1.5C to 2C is likely to increase the intensity of total precipitation of very wet days 1.8 times and double maximum five-day precipitation”.
Prof Yang Chen of the Chinese Academy of Meteorological Sciences at the CMA tells Carbon Brief that human-caused intensification of heavy rainfall over China had been even larger than expected. He explains:
“Human-caused intensification of heavy precipitation over monsoonal China is markedly larger than expected from increases in atmospheric moisture due to warming, because of stronger feedback between latent heat releases and ascending motion within wetter storms in a warmer climate.”
Such feedback, he adds, is particularly evident in eastern China compared to other regions of similar latitudes.
A recent study in Nature also anticipates storm activity over China to become more frequent and intense as a result of warming. By the end of the 21st century, the annual average frequency of tropical cyclones on the east coast of China is anticipated to increase by 16% compared to the present day, according to the study.
Apart from climate change that is caused by human activities, poorly designed and constructed cities, as well as subsidence – caused by groundwater extraction, the weight of buildings as result of urban growth, urban transportation systems and mining activities – could also amplify floods.
Dr Kevin Smiley, assistant professor from the department of sociology of Louisiana State University tells Carbon Brief:
“Climate change is increasing the severity and frequency of extreme weather. Extra rainfall induced by climate change can be the difference between a building’s parking lot hosting puddles on a rainy day compared to floodwaters crossing the threshold of the building and causing thousands of dollars of damages.
“It’s always important to remember: climate change is anthropogenic, so this increased risk also has human-caused roots.”
How is China adapting to increasingly frequent flooding?
China has built a number of large water projects to prevent flooding, such as the south-north water transfer projects in the Yangtze river that was launched in 2002.
In the most recent “national water network construction planning outline” published by the State Council – China’s top administrative authority, the equivalent of central government – constructing “national water networks” by 2035 is among the “backbones” of future flood prevention.
The “backbones” in the document also include large hard-engineered structures on the main rivers, such as embankments, flood gates and channelised river networks, to mitigate flood risks.
Meanwhile, a study published in the journal Ocean & Coastal Management found that “nature-based solutions” have also become popular in China. The restoration and conservation of freshwater swamps, mangroves and wetlands along coastlines and river mouths are being used to provide a buffer for tidal and storm surges.
They include the Chongming Island wetland in Shanghai (Yangtze delta) and the Futian and Mai Po wetlands in Shenzhen Bay (Pearl River delta).
Another concept proposed in the planning document is to “accelerate smart development” by using the internet, data and technology to monitor and prevent floods.
The capital Beijing has incorporated data from high-definition cameras, as well as telescopes, radar maps and satellite cloud images to provide real-time hazard updates, which has improved emergency response times.
Ningbo, a port city on China’s east coast, has worked with mobile companies to analyse big data and disseminate information.
The Ministry of Emergency Management said these measures have reduced the number of deaths and missing people as a result of natural disasters by 54% over 2018-22, compared to 2013-17. The death toll continued to fall in 2023 but the number of destroyed buildings and direct economic losses rose by 97% and 13%, respectively, compared with 2018-22 levels.
In 2015, the sponge city programme (SCP) concept was written into a policy document of the Ministry of Housing and Urban-Rural Development. It was promoted across the country and 30 major cities, such as Wuhan (home to 11 million people) and Zhengzhou (home to 10 million people), were chosen to be the pilot cities.
Those sponge cities are designed to collect, purify and re-use at least 70% of the floodwaters through “green-blue facilities”, such as green roofs, permeable pavements and stormwater parks, in urban areas. The overall system was meant to resolve the issues of urban heating, freshwater scarcity and flooding all at once.
China has improved its recovery process too. In Ningbo, for example, flood victims were able to access financial compensation within an hour, using an improved online documentation process during Typhoon In-Fa in 2021.
How effective are these measures?
Chan tells Carbon Brief that China has “done very well in terms of preparation, response and recovery for flood and drought hazards” – the two most destructive types of natural disasters.
“As a global south country,” he says, referring to China as a developing country, “China has done quite well with the SCP [sponge cities programme] and the ecologically enhanced solutions for addressing climate change”.
However, Wing argues that nature-based solutions, such as SCP, can “get saturated quickly” and so “there’s a risk of their role being overstated”. He continues:
“These types of interventions are most effective for rainfall events which occur relatively regularly at low intensities. They will be quickly overwhelmed during the very intense, rare rainfall events (whose probabilities are changing rapidly in a warming world) that cause the most damage and suffering.”
In 2021, a “historically rare” rain and flood, that affected more than 14 million people and killed 398 in Zhengzhou, a showcase sponge city, highlighted the limitations of the SCP in the face of climate change.
SCP is designed to only withstand one-in-30-year rain events, says the Nature study. On top of that, it can create a false sense of security, which encourages more people to move to high-risk areas, leading to an increase in population and assets in exposed areas that require ever-increasing protection in a cycle referred to as a “levee effect”, says Chan.
The levee effect refers to the paradox whereby the construction of a flood-defence levee leads to a lowered perception of flood risks and a greater likelihood of property owners investing in their property, increasing the potential damages should the levee breach.
The effect, according to the Nature paper, is a key challenge in the densely populated Yellow River delta and Pearl River areas, which both face high risks of flooding.
Smiley says:
“Risk is realised when social vulnerabilities intersect with hazards. Vulnerabilities are social. Flood impacts are greater when social vulnerabilities are greater…Social vulnerabilities are uneven. A household with some wealth and good insurance can recover from a flooding event much faster and more successfully than a household living paycheck-to-paycheck.”
The Chinese government has allocated more than one trillion yuan ($138bn) – via a special government bond – to support the vulnerable citizens and reconstruction of areas hit by natural disasters in March this year. More than half of the funds are used for “the construction of water conservancy projects like flood control,” reported state media outlet the Global Times.
But the delivery of financial support has been questioned in the past. When Typhoon Doksuri hit China in 2023, only $2bn out of roughly $25bn in aggregate losses were underwritten, according to global reinsurer Munich Re.
In addition, the construction of those sponge cities has already cost China 1.5-1.8bn yuan ($210-250m) between 2015 and 2018. And maintenance will make this bill even larger.
The authors of the Nature paper suggest that the government should work on integrating fragmented “grey infrastructure” – built structures such as drains, pipework and pumping stations – into existing green-blue facilities, but should not rely on engineered infrastructure alone.
Dr Lele Shu, a researcher at the northwest institute of eco-environment and resources, Chinese Academy of Sciences, tells the Intellectual magazine that “the [impact of] heavy rain at the current rate cannot be mitigated through traditional engineered approaches alone”.
“Everytime there is heavy rain, the damage it causes will make headlines primarily because there are too many people living in the city,” adds Shu.
The lack of coordination between regional governments and municipalities in flood prone areas also often led to fragmented approaches to disaster management.
In the case of the Yangtze and Pearl deltas, there is a lack of delta-wide plans that “systematically zone land and prioritise investments within one unified hydrological system”, the Nature study adds.
Dr Zheng Yan, a researcher at the Research Institute of Eco-civilisation, China Academy of Social Sciences, noted in the aftermath of the 2023 Beijing flood that government bodies often look after their own jurisdiction and aim only to move the problem and divert the floods quickly, which piled pressure on cities in downstream areas.
Smiley says:
“Floodwaters don’t care about human-created boundaries by municipality, district or province. Effective urban design in one locality may lessen flood risk there, but indirectly increase risk elsewhere. Thinking collectively while centering justice means providing spatially extensive and locally attuned solutions that help all recover effectively instead of exacerbating inequalities.”
What can China learn from other cities?
As flooding is a challenge faced by cities across the world, there is a plethora of ideas and technologies that China can draw on.
The Nature paper suggests that the Yangtze and Pearl deltas, for example, could learn from the Ganges-Brahmaputra-Meghna delta and the Mekong delta to “improve their responses to regional challenges such as subsidence and erosion, by using and aligning with the underlying dynamics of the deltas that are rapidly changing in response to climate change and anthropogenic activities”.
Building a resilient society that is “proactive and forward-looking, with adequate capabilities to limit detrimental flooding impacts and timely return to the pre-disaster state” is also advocated by the paper.
Rotterdam, a Dutch delta city of 600,000 people that is surrounded by water on four sides, has built water storage facilities, such as an underground parking garage with a basin the size of four Olympic swimming pools. It has also installed green roofs and facades to absorb rainwater.
Japan has built an intricate network of concrete tunnels and vaults about 14 storeys beneath the Saitama prefecture in the outskirts of Tokyo, Japan’s capital city, that can hold more than 1,000 Olympic pools of rainwater.
Both cities’ underground flood diversion facilities are often used as a prime example of a viable flood defence system for urban cities on the frontline of climate change.
Hong Kong has a similar underground stormwater storage system beneath the sport pitches of the Happy Valley Racecourse, designed to withstand once-in-50-years flood events.
However, Chan says it is difficult to compare flood mitigation measures as each city is very different in terms of geography, demographic, densities and topography.
He tells Carbon Brief:
“But in my opinion, China’s megacities should think about using underground spaces to store the sudden extreme discharge from super intensive rainstorms…Tokyo and Rotterdam are quite wise (in that regard) for using their underground spaces.”

Q&A: How China is adapting to increasingly frequent flooding
A relatively ambitious deal to reduce the shipping industry’s 3% of global emissions now looks more likely after four days of closed-door talks in London, observers say.
The International Maritime Organization (IMO), which oversees the negotiations, said there had been “constructive discussions” and “genuine willingness within the group to make concrete further progress”.
Em Fenton, senior director at the NGO Opportunity Green who attended the talks last week, said they “demonstrated a strong spirit of solidarity in the face of blatant attempts to undermine the credibility, ambition and equity of a hard-fought multilateral agreement”.
After several years of debate, governments provisionally agreed in April 2025 on a “Net-Zero Framework” (NZF) – a series of emissions reduction targets for shipowners aimed at incentivising them to use cleaner fuels, backed up with financial rewards for meeting the targets and fees for missing them.
But in October 2025, after a high-profile intervention by US President Donald Trump and threats of US sanctions and visa restrictions, the US convinced a majority of voting nations to postpone the adoption of the NZF for a year.
UCL analysis found that, of those who expressed a view at last week’s talks, 38 were in favour of an NZF-style solution while only 17 were against. Those opposed are “consistently composed of strongly fossil fuel-aligned governments”.
An observer of the talks, who did not want to be named, said the countries opposed include the US, Russia, India, Thailand, Argentina, Ecuador and Uruguay, as well as eight oil-rich Gulf nations and shipowner-reliant Liberia and Panama. Governments that support an NZF-style deal include China, Brazil, Mexico, Türkiye, Canada, Australia, Chile, nine African nations, most European countries and small islands.
A new framework to tackle shipping emissions could be adopted if two-thirds of countries that are present and signed up to a regulation called Marpol Annex VI – endorsed by just over 100 states – vote in favour of it, as they did in April 2025.
UCL’s analysis said it was “reassuring” that governments which had taken strong positions in the media against the NZF were being more compromising in the negotiations.
Tweaks are probable
While there is majority support for the NZF, UCL said adopting it would be difficult politically. “The process from here could therefore be as much about producing what appears to be a new package, but one that broadly ends up with similar outcomes in relation to objectives,” UCL argued.
But tweaking the NZF, which resulted from years of negotiations, comes with risks, it warned. For example, changes could reduce the new system’s planned support for low-income countries, turning them against it. Fenton said compromising should not mean “abandoning the principle of justice in the maritime transition”.
UCL said the speed at which shipowners must reduce their ships’ emissions or face fees is likely to be reduced in the short-term but raised in the long-term to meet a goal of net zero emissions by mid-century.

Loss and damage fund urged to hold crisis meeting on Nepal

This was a compromise put forward by NZF-supporter Brazil. However, an analysis by the the Institute of Marine Engineering, Science and Technology (IMarEST) has found that this change would lead to more overall emissions than the original NZF trajectory.
UCL has warned it could incentivise liquefied natural gas as a shipping fuel over greener options, which include hydrogen-based methanol and ammonia.
Analysis by UCL and the Rocky Mountain Institute suggests that, while a slower start to the NZF would reduce transport costs in the short term, it would increase them later due to the costs involved in switching the industry over from more polluting fuel to cleaner fuel.
NZF won’t meet emissions goals
IMarEst’s analysis finds that even in its current form – the most ambitious deal on the table – the NZF will not be sufficient for shipping to meet its emissions reduction goals.
It says that only a Pacific proposal to place a levy on ships’ total emissions – rather than just those above a certain level – would meet the industry’s targets to reduce emissions 20% between 2008 and 2030, 70% by 2040 and then reach net zero “by or around, i.e. close to 2050”. This is highly unlikely to be adopted.
Additional talks will be held from November 23-27 and from November 30-December 3 before a potentially final round of official negotiations begins on December 4.

At regional summit, Pacific islands ask for COP31 support for clean energy and finance
At a key leaders’ summit in Palau, Pacific island nations burdened by worsening climate change impacts and costly fossil fuel imports called for November’s COP31 climate summit to deliver finance to help the region transition to renewable energy and build more resilient communities.
Heads of government from the 18-member Pacific Islands Forum (PIF) – which includes COP31 co-president Australia – met in Palau’s capital Koror for a week-long summit, where they demanded access to climate finance, ocean action and a regional boost for renewables at COP31.
Palau’s president Surangel Whipps Jr. said during a plenary session that the Pacific must focus on delivering climate and ocean commitments. “It will require greater regional leadership, stronger regional coordination and, above all, unity of purpose,” he said.
The meeting, which ended last Friday, was marked by the absence of some leaders – among them the heads of state of the Solomon Islands, Vanuatu and Fiji, which will host a preparatory session for COP31 in October (referred to as the pre-COP31). There were also tensions over Taiwan’s participation, with China objecting to its presence as an observer.
The forum’s final declaration, published after it ended and signed by all its members, reaffirms that climate change is the “single greatest threat to the security, livelihoods and wellbeing of Pacific peoples”, and notes “the importance of a focused, high-level declaration” at the pre-COP31 to build “political momentum towards COP31”.

Australia and Pacific islands have invited world leaders to attend the pre-COP31 gathering, which will be held in Fiji and Tuvalu from October 5 to 8. While usually a technical meeting for negotiators, the island nations aim to issue a political declaration at the gathering calling for strong outcomes in Türkiye.
Chris Bowen, Australia’s climate minister and COP31 president of negotiations, said in a speech during the Pacific forum that his country is “determined to use COP31 to progress the agenda to make it easier for countries to access the climate finance they need”.
“We won’t miss the opportunity to ensure COP31 is a Pacific COP. Not just because of the location of pre-COP but because of the agenda we are shaping through the Action Agenda at COP31,” he said.
The Action Agenda is a large portfolio of climate initiatives and coalitions uniting governments, businesses and civil society outside of the formal negotiations on everything from health to methane emissions.
Renewable energy investment plan
Announced a year ago, the island nations launched a $14-billion investment plan for a “100% Renewable Blue Pacific” at the forum in Palau. The plan lists strategic projects that would reduce the region’s high dependence on fossil fuel imports, whose soaring costs have become a major burden since the Iran war.
The projects include a $52-million programme managed by Australia to develop off-grid renewables in remote communities across the Pacific, as well as a $100-million blended finance fund aimed at supporting private-sector investments in wind and solar, among others.
Currently, some countries in the Pacific are spending up to a quarter of their GDP importing diesel to power electricity generation, according to a new report by the University of New South Wales in Australia. The investment plan launched at the forum aims to reduce these costs by adding 2.2 gigawatts of renewable generation and around 9 gigawatt hours of electricity storage.
To channel funds into the region, the plan also highlights the role of the recently established Pacific Resilience Facility (PRF), a regional fund that seeks to swiftly disburse funds to climate-vulnerable communities at the local level. Bowen said he would promote the facility to world leaders attending COP31 and “ask for their support”.
Call to transition away from fossil fuels
Separately, the forum endorsed the Belau Declaration which emphasises the need to keep the 1.5C Paris Agreement temperature goal alive. A UN report last week showed that overshooting this limit is now inevitable, but deep emissions cuts could still bring global temperatures back down by the end of the century.
Pacific nations expect to rally support for this declaration at the pre-COP, with Fiji’s climate minister Lynda Tabuya saying in a statement: “Palau is where we build the political mandate. Pre-COP is where we take it to the world.”
The political declaration also says that countries must accelerate the global transition away from fossil fuels “towards a renewable energy future”, and calls for greater recognition of the importance of ocean health in addressing climate change.
UN sets out narrow path back to 1.5C warming after inevitable overshoot
As part of the forum’s outcomes in Palau, countries also noted Tuvalu’s efforts to host the second global conference on transitioning away from fossil fuels, which will gather government representatives in April next year to follow up on this year’s inaugural conference in Santa Marta, Colombia.
Speaking to journalists at the forum, Vanuatu’s climate minister Ralph Regenvanu questioned Australia’s role in talks about phasing out fossil fuels at COP31, adding that “the very least a country like Australia should be doing is stopping future expansion, and it’s not doing that”. During the PIF, the country approved the extension of a major mine that digs and exports coal for steel-making, giving it permission to keep producing until 2055.
Rising seas trigger “development emergency”
As leaders met in one of the world’s regions most threatened by sea-level rise, UN Secretary-General António Guterres released a new report warning that rising seas are now “one of the most profound threats to populations around the world in developed and developing states alike”.
Presenting the report at UN headquarters in New York, Assistant Secretary-General for Economic Development Navid Hanif said rising sea levels are not a “future risk any more” but an accelerating “development emergency” that could hinder progress in vulnerable regions like the Pacific and least developed countries.
The report warns that seas are rising “faster than at any point in recorded history”, with 2024 setting a new record of 5.9 millimetres. This has been driven by human-induced climate change mainly through a process known as thermal expansion – where rising heat causes the ocean to expand – as well as the melting of ice sheets.
Pacific islands seek backing for new regional fund ahead of COP31
The report notes that about 1.2 billion people around the world are exposed to coastal flooding, and says some low-lying islands in Vanuatu, the Solomon Islands and Fiji are already facing forced relocations. Globally, rising seas could cost more than $1 trillion every year by 2050, it adds.
“We cannot stop sea level rise this century but we can determine how much worse it becomes. About half a metre of sea level rise is already locked in in this century because of warming that has already occurred, but beyond that our choices matter enormously,” Hanif told journalists.
Bill Hare, CEO of think-tank Climate Analytics, said the report was a “wake-up call” to the leaders of high-emitting countries that their failure to cut carbon emissions is “creating major risks for the future alongside the impacts we can already observe around us”.
Guterres is set to host a high-level meeting on addressing the threat of sea level rise this month during the UN General Assembly, where countries are expected to adopt a declaration that calls for stronger action, expanded access to finance and “ongoing dialogue” to tackle the issue.

At regional summit, Pacific islands ask for COP31 support for clean energy and finance
Israel’s bombardment of Gaza during the conflict that broke out in October 2023 has wrecked progress towards adapting the enclave to climate change and left two million Gazans vulnerable to heatwaves, drought and disease, the Palestinian Authority (PA) said in a new climate plan submitted to the United Nations.
Palestine’s third nationally determined contribution (NDC), uploaded to the UN climate body’s website this week, says that while “the aggression on the Gaza Strip did not make the climate worse”, “it removed the housing, water and sanitation systems, health facilities, energy networks, roads and livelihoods through which people absorb a climate they were already struggling with.”
The 91-page document lists the types of infrastructure it says Israel has destroyed and notes how the destruction will worsen the impacts of climate change. It says the bombing of hospitals and rising hunger have make it harder for Gazans to cope with the health impacts of climate-driven heatwaves and waterborne diseases.
The destruction of water tanks, boreholes and desalination plants, meanwhile, have left Gazans struggling with the effects of water shortages and drought, while mass unemployment reduces people’s ability to afford climate-driven price rises. The erasure of most of the Strip’s homes makes it more difficult for people to avoid the sun’s increasing heat, the NDC said.
Many Gazans are now living in the ruins of collapsed buildings or in makeshift shelters and tents that offer little or no protection from high temperatures.
Palestine’s previous goals to cut emissions and adapt to climate change in Gaza, expressed in its last NDC five years ago, were based on a pre-war baseline that “no longer describes anything that exists”, the NDC says. Progress made since 2021 has now been destroyed, it adds.
Green reconstruction of Gaza
Instead of continuing to aim for these adaptation and emissions-reduction goals, the PA is now calling for the green reconstruction of Gaza. It says buildings should be constructed again in an energy-efficient manner with solar panels and served with modern water, waste and transport systems.
While the PA, controlled by the Fatah political party, continues to claim legitimate control of Gaza, the strip was effectively governed by Fatah’s rival Hamas between 2007 and the recent war. Control is now split between Israel and the political wing of Islamist militant group Hamas, after a US-backed ceasefire took effect in October 2025, although a UN-backed committee plans to take over.

More support needed to power Africa’s food systems with renewables, experts say
Renewable energy could help African food businesses boost productivity and competitiveness, but the upfront cost, fragmented markets and limited financing stand in the way
The United Nations, European Union and World Bank have jointly estimated that Gaza needs $71.4 billion of investment in the next two years to recover and build back. This process should be Palestinian-led, they said in April.
But US President Donald Trump has said the US should “take over” and “own” Gaza and redevelop it as the “Riviera of the Middle East”. Israel’s right-wing prime minister Benjamin Netanyahu has said that Israel should control the territory with civil administration managed by Palestinians favourable to Israel.
With occupation, targets conditional
In the other part of Palestine, the West Bank, the Palestinian Authority carries out some government functions, but ultimate control rests with Israel, which has occupied the West Bank since 1967.
Because Israel controls planning in most of the West Bank, the NDC argues that the PA cannot pursue all the climate projects it wants. In addition, Israel restricts the movement of PA officials, making data collection difficult, and controls the West Bank’s electricity supply meaning that the PA cannot control whether it comes from dirty or clean sources of energy.
Given this situation, the NDC says that all of Palestine’s new climate targets are conditional but it will aim to reduce emissions 12.8% below a business-as-usual baseline by 2035 and 17.1% by 2040. If the Israeli occupation ends and Palestine regains full sovereignty over its land and resources, it will aim for reductions of 15.1% and 19.1% by 2035 and 2040 respectively under an “independence pathway”.
That could allow, for example, for greater electrification and reducing emissions per unit of growth, the document said.
To achieve the 2035 emissions-reduction target and adapt to the impacts of climate change, the PA says it needs $8.6 billion in total. This funding would be spent on measures like encouraging solar farms and rooftop solar and scaling up solar water heating to cover four-fifths of households. To complement the planned increase in solar power, the authority wants to modernise the electricity grid and install battery storage.
In the transport sector, it aims to promote the uptake of electric vehicles, develop bus rapid transit corridors and scrap old polluting trucks and buses. In Gaza in particular, it wants to deploy 66 electric buses when the conflict ends.
To adapt to climate-driven drought, the NDC includes initiatives to reuse wastewater through treatment plants, build desalination plants in Gaza to remove salt from seawater, and promote irrigation for farmers.
The new climate plan was prepared by Palestine’s Environment Quality Authority, with support from the United Nations Development Programme and the governments of Britain and Spain.
The United Nations recognised Palestine’s statehood in 2012 and it joined the UN’s climate convention and signed the Paris climate agreement – which requires countries to submit more ambitious NDCs every five years – in 2016.
The Israeli foreign ministry did not respond to a request for comment. But in late 2024, then Israeli climate envoy Gideon Behar told Climate Home News that the war and the resulting environmental destruction in Gaza was the fault of Hamas.
