中国国家主席习近平于2020年承诺在2060年前实现碳中和,此后中国围绕能源转型的思路发生了巨大转变。
然而,尽管此后中国出台了一系列重大政策,但目前仍不明确什么是新的能源系统,以及中国实现碳中和目标的最有效途径是什么。
我们的最新研究为中国能源转型建立了三种情景模型:一种是中国在2055年前建立净零排放的能源系统;一种是中国在2055年左右实现这一目标;还有一种是推断当前发展趋势的基线情景。
我们发现,将能效措施、终端用能消费电气化和基于各种可再生能源(如太阳能和风能)的低碳电力供应结合起来,可以极大地帮助该国在2055年前实现脱碳目标。
在最高情景下,中国的电力部门到2055年将不使用化石燃料,而一些行业将继续使用少量煤炭和天然气。然而,配备碳捕集与封存技术的生物质发电厂所产生的负排放将对此起到平衡作用。
双碳目标如何改变局势
2020年9月,当习近平开始在联合国大会上发表演讲时,几乎无人预料到中国会发表如此具有开创性的宣言。

他说:“中国将力争2030年前实现碳达峰、2060年前实现碳中和。”
这一政策现在更多地被称为“双碳”目标。
这句话改变了人们对中国能源转型的整体认识。
在此之前,中国在2017年“十九大”上的目标是“要推进能源生产和消费革命,构建清洁低碳、安全高效的能源体系。”
而习近平在2020年的讲话将中国的优先发展从实现“低碳”转变为实现“碳中和”,使能源部门从至少包括部分化石燃料消费,转变为一旦实现碳中和就几乎不给煤炭、石油和天然气留下空间。
要实现这一转变,需要处于中国政策体系和能源系统的利益相关者,如主要发电企业,真正改变思维方式。
中国在宣布碳中和目标后立即开始行动:国务院推出了“1+N”政策体系,其中包括实现“双碳”目标的总体纲领性文件(“1”)和实施该战略的一系列更具体的指导方针和法规(“N”)。
到目前为止,这些政策主要侧重于在2030年之前实现碳达峰。不过,在2060年之前实现碳中和的长期目标始终存在。
国家能源局发布了一份新型电力系统发展蓝皮书。在更广泛的层面上,多个政府部门已提出要为实现碳中和而推动整个能源系统——而不仅仅是电力系统——进行转型。
因此,今天中国能源转型的基础比习近平宣布之前更加坚实和精确。现在的问题是:新型能源系统将是什么样子,中国将如何实现这一目标?
中国能源转型的三种情景
为了回答这些问题,我们的研究模拟了中国能源转型的三种情景:一种是中国在2055年前建立一个净零排放的能源系统;一种是中国在2055年左右实现这一目标;还有一种是推断当前发展趋势的基线情景。
该分析基于一种详细的自下而上的建模方法,同时将“美丽中国”愿景——实现“绿色和高质量增长”的官方倡议——作为转型的指导方针。
在我们的模型中,能源转型的总体战略包括三个紧密相连的行动:
- 提高整个供应链的能源效率;
- 尽可能使终端用能部门电气化;
- 将电力部门转变为以太阳能和风能为支柱的“绿色”、无化石能源部门。
(政府间气候变化专门委员会的最新评估报告显示,这些是将升温控制在1.5°C或2°C的所有全球路径的关键要素。)
遵循这一战略的结果是,中国的能源系统将能够为中国可持续的经济增长提供动能,同时实现净零碳排放、空气质量改善和高水平的能源安全。
在最高情景下,中国的电力系统将从2045年起实现碳中和,整个能源系统将在2055年前实现碳中和。
与今天的情况相比,尽管经济有所增长,但2060年的一次能源消费总量将有所下降。此外,煤炭、石油和天然气将几乎被逐步淘汰,对进口化石燃料的依赖将被消除。
下图显示了2021年中国经济的能流(上图)与2060年在最高情景下的能流(下图)的对比。
在左侧,各版块显示了流入经济的一次能源来源,如煤炭(黑色)、天然气(粉红色)、石油(灰色),以及非化石燃料,如核能(棕色)、水能(深蓝色)、风能(浅蓝色)和太阳能(黄色)。
各版块的中心都显示了一次能源转化为更有用形式的过程,如电力或精炼油产品。化石燃料中所含的大部分一次能源在这一阶段以废热的形式被浪费(“损失”)。
右侧是按部门划分的最终能源用户。
最值得注意的是,化石燃料(尤其是煤炭)是2021年最大的能源来源,而在雄心勃勃的2060年情景(见下图)中,低碳能源则占主导地位。


中国能源转型的三个阶段
我们的研究表明,转型之路将分为三个主要阶段。第一阶段是2030年前的碳达峰。
在此期间,风电和光伏发电的部署将继续增加,同时工业和交通部门的电气化也将取得进展。
然而,就一次能源消费总量而言,煤炭和石油仍将是最主要的初级能源消费。
接下来是“能源革命”阶段,从2030年到2050年。在这一阶段,光电和风电将成为电力供应的主要来源,终端用能部门的电气化程度将大幅提高。
摒弃化石燃料可以最大限度地减少发电和提炼过程中的废热损失。同时,利用可再生能源生产的“绿氢”在工业领域将变得越来越重要。
第三阶段是巩固阶段,从2050年到2060年。脱碳发生在钢铁和化工等难以实现电气化的细分部门,旧的风光发电厂将被新的风光发电厂取代,能源组合中剩余的化石燃料几乎被淘汰。
煤电成为灵活性提供者
虽然中国政府计划从2025年起“逐步淘汰”煤炭,但根据当前的政策方针和市场情况,我们估计在三种情景中,煤电装机都不会迅速消失。
相反,燃煤电厂将逐渐成为保障能源安全和满足电力需求高峰的能力提供者,而不再进行大量发电。
当燃煤电厂达到30年左右的预期寿命时就将被关闭,而不会被新的煤电装机所取代。如下图所示,在我们最高情景中,最后一批煤电厂将于2055年关闭。
图中上半部分显示了2021年至2060年燃煤电厂的装机容量,下半部分显示了燃煤电厂的发电量。


与此同时,在我们的情景中,天然气在电力部门作用有限。这是因为光电和风电可以提供更便宜的电力,而现有的燃煤电厂——加上储能和需求侧响应设施的大规模扩张——足以提供灵活性和调峰能力。
管理由多变的风电和光电主导的电网
依赖光电和风电作为主要电力来源的能源系统,需要采取特殊的灵活性措施促成供需有效匹配。
下图显示了在2055年前实现碳中和的雄心勃勃的情景下,2060年夏季一周内每小时电力平衡的模拟示例。
图中上半部分显示的是供应侧发电量。在白天,光电(黄色)在电力生产中占主导地位,而风电厂(浅蓝)在24小时内都有更稳定的输出。
在傍晚和夜间,储能(紫色)会被释放,水力发电量(深蓝)高于白天。
图中下半部分显示的是需求侧的用电情况。储能(紫色)在白天充电,电动汽车智能充电(蓝色)在一周内提供灵活性。

作为后备电源,电动汽车车网互动发挥着重要作用——其不一定是重要的能源供应商,而是在风电和光电输出有限时,成为必要时可以启用的最后手段。该方案是保证电力系统容量充足的一种经济、高效的方法。
在2055年之前,煤电厂同样可能是电力系统可靠且经济的容量提供者,尽管如前所述,其平均发电量并不高。
从日常调度(管理供需的过程)的角度来看,这种创造灵活性的方式似乎很复杂。然而,一个高效且运作良好的电力市场(包括消费者和生产者)可以做到这一点。
消除各省之间的电力交易障碍、构建全国统一的电力市场,将是实现这一目标的关键因素。
未来远景规划
我们在《中国能源转型展望》(China Energy Transformation Outlook)中的情景对净零排放能源系统的长期未来提供了一系列量化远景规划。
我们对电力系统和其他能源终端用能部门建立了详细的模型,从而可以将这一新能源系统的发展与实现这一转变的政策措施联系起来。
我们研究得出的一个关键结论与上述中国能源转型不同阶段的时机有关。我们的模型表明,成功协调这些阶段至关重要,这样才能在保持能源安全的同时避免对能源基础设施进行不必要的投资。
我们情景中的其他关键推动因素包括扩大电网所需投资、国家电力市场的发展和对能源系统灵活性的支持。
即使有最优的远景规划和从我们的路径中获得的洞见,中国要实现2060年的目标仍有许多需要克服的挑战和障碍。
然而,我们的情景表明,有一些可行且具有成本效益的路径可以在不等待新技术突破的情况下实施。

Pacific leaders rail at climate finance failures after pre-COP trip to Tuvalu
After witnessing the effects of sea-level rise in the low-lying island nation of Tuvalu, Pacific leaders on Tuesday used the pre-COP31 summit in Fiji to voice their frustration at the difficulties they have experienced in tapping the global climate finance system.
A small group of government leaders, climate negotiators and heads of development banks and climate funds took a trip to Tuvalu’s Funafuti atoll on Tuesday morning, travelling by road over land just 10-20 metres wide to visit a project that is building barriers to keep the sea from the land.
They then flew to Fiji for the pre-COP summit, where several Pacific leaders said they had been let down by the insufficient quantity, bad terms and slow speed of international finance to help them adapt to a warming climate that is bringing higher oceans, drought and more powerful storms to their shores.
“Right now, our islands are like a canoe that has been rammed by a massive foreign ship. Our canoe is taking on water, we are sinking, and what is the world’s response?” asked Palau’s President Surangel Whipps Jr.
“They hand us a tiny patch to cover a gaping hole,” he continued, “but the bureaucratic process just to receive that patch is so slow that the water fills the hole while we wait. Then to rebuild the vessel so that we can survive the next storm, we are offered loans, debt that adds weight to a sinking boat packaged in red tape so thick we can barely access it. And while we wait, the water continues to fill.”

Pacific leaders and Australia called again on governments to invest in the new Pacific Resilience Facility (PRF), which has been designed by the Pacific Islands Forum and is seeking $500 million in investments by COP31 in November.
It has around $180 million so far, but did not receive additional pledges during the UN General Assembly in New York. The PRF aims to invest to generate annual returns which it can give to projects like water tanks for drought-hit communities.
Witnessing sea level rise
The annual pre-COP gathering is usually a low-profile technical meeting of climate negotiators. But this year, Australia – which is the president of negotiations at COP31 – partnered with the Pacific to introduce a “leaders segment” in an attempt to shine a spotlight on climate issues affecting the region.
Fourteen government leaders – from Australia, Timor-Leste, Mauritius and the Pacific – made the trip. They were joined by the European Union’s climate commissioner Wopke Hoekstra, the heads of the Green Climate Fund and the Asian Development Bank and former Australian prime minister Julia Gillard.

On their return to Fiji, Solomon Islands Prime Minister Matthew Wale told the pre-COP leaders roundtable that the sea level rise they had witnessed was personal for him.
“Tuvalu was not just a site visit for me. I saw the story of my own saltwater people,” he said, adding that he, his daughter and his grandfather had lost their houses to sea level rise and that three-quarters of his electorate live on land that will be underwater in the next 30 years.
From the other side of the world, Antigua and Barbuda’s environment minister Michael Joseph said Tuvalu’s problems felt similar to those of his own Caribbean islands. “I saw vulnerable communities… just metres from the sea and people determined to remain on their land, preserve their culture and way of life,” he said.

A group of Fijian schoolchildren told the leaders it was not just sea level rise the Pacific struggles with but also heatwaves, droughts and storms, which worry their families and prevent them from learning.
Climate finance red-tape
Several Pacific leaders criticised the world’s leaders for not doing enough to combat climate change. Cook Islands Prime Minister Mark Brown expressed disappointment that only two non-Pacific leaders had come to the pre-COP, a fact Australian media widely picked up on to label the event a flop and question its A$20 million (US$14m) price tag.
“We’ve heard a lot of numbers these last two days,” Brown said. “Let me share one of my own. More than 50 invitations extended to world leaders… to see for themselves what high emissions are doing to our nations and our ocean – an ocean that covers nearly one-third of the Earth’s surface.”
He called for more climate finance for the Pacific, asking “if the world is prepared to assess our suitability for climate finance, why is it not equally prepared to scrutinise whether those responsible for delivering it are meeting their obligations?”
Like Palau’s president Whipps, Naoero’s President David Adeang criticised the red tape that is hindering access to climate finance as well as a lack of money, complaining especially about “complicated procedures, heavy reporting, delays in approval and disbursement”.
Adeang added that “the way we assess vulnerability matters”, adding that it should be measured by more than income. Naoero, for example, is classified by the World Bank as high-income, restricting which climate finance it is eligible for.
Action plan to improve access
On Thursday, the Australian government will present a statement and action plan on improving access to climate finance for small island developing states and least developed countries, which it is asking other countries and organisations to endorse.
The statement addresses some of these Pacific complaints as well as acknowledging that progress has already been made on simplifying access by multilateral development banks and climate funds.
In Fiji, Asian Development Bank head Masato Kanda said his institution is “tailoring our finance and operations to island realities” because “your children and their children should be able to grow old in the countries their ancestors have called home for millennia”.
The executive director of the Green Climate Fund (GCF), Mafalda Duarte, said that the GCF-backed coastal adaptation project leaders visited in Tuvalu shows that “climate finance works” although – as the project took eight years to implement – “it takes time, and therefore we have no time to waste”.

Australia calls for optimism
While Pacific leaders expressed concern that the world is set to blast past its agreed 1.5C warming limit, endangering their nations, Australia’s Prime Minister Anthony Albanese called for “optimism”. “If people think there is no hope, then they will not strive to get the change that we need,” he said.
He said that when he attended his first COP in 2005, Australia’s renewable energy target was 2%. Its target is now 82% renewable electricity by 2030.
While Albanese promoted Australia’s success at electrifying homes and businesses and rolling out renewables, he has been criticised by climate campaigners for extending the production of fossil fuels, including coal – largely for export.

France’s Minister for Ecological Transition Monique Barbut defended the European Union’s climate action at the pre-COP meeting. She said the continent was heating up and reducing emissions faster and providing more climate finance than anywhere else in the world.
“It is time for all major emitters to step up and do their fair share” on climate finance, she said. Most developing countries with large emissions have fiercely resisted joining the club of climate finance donors, arguing they have played a disproportionately small historic role in causing climate change.
Barbut, as well as Palau’s president Whipps, called for the next flagship scientific assessment report of the Intergovernmental Panel on Climate Change (IPCC) to be finished by COP33 in 2028, in time to inform the next global stocktake of national climate action.
This timeline has been opposed by countries like India, Saudi Arabia and China, who argue it would put an unfair burden on developing countries. Barbut said countries should “support the work of the IPCC rather than sabotage its calendar”.
Barbut said that governments should agree at COP31 to aim to raise the share of “clean electricity” in final energy consumption to 35% by 2035. The Turkish and Australian governments have pushed for this goal although without specifying that the electricity should be “clean”. Barbut added that COP31 should also agree to cut emissions of methane, a particularly potent greenhouse gas.

Coal mines and hypocrisy must not be Australia’s COP31 legacy
Jacynta Fa’amau is a Pacific campaigner at global grassroots climate movement 350.org and a secretariat member of Pacific Climate Warriors.
The first thing that struck me was the sheer size of Queensland’s Saraji coal mine. Standing at the edge of the enormous pit, my brain scrambled for words as I scanned the earth’s open wound – a whole island could probably fit inside it.
Looking down, I noticed footprints of an emu and a koala, pressed and dried in what was once a puddle – signs of how drought had driven animals in desperate search of water, so dangerously close to the coal trucks and heavy machinery ahead.
Earlier this year, I joined a small group of Pacific Islanders on a journey through the Bowen Basin to learn from First Nations communities battling Australia’s mammoth coal industry. Of the more than 40 coal mines operating in the area, BHP & Mitsubishi Alliance’s Saraji mine is one of the largest. So it came as a painful shock to us when in August, the Australian government approved the mine’s extension just months after our visit.
Witnessing coal extraction is devastating. It is bad enough to see what pillaging tonnes of coal can do to a mine’s immediate surroundings: dry creek beds, dwindling wildlife, denuded land. But to know that this coal will be shipped across the ocean, bring air pollution, and eventually lead to the destruction of Pacific islands thousands of miles away is another kind of heartbreak.
Rising ocean waters
I’m an Australian-born Samoan. In 2002, I visited my family home for the first time. My father took me to the rural community where generations of my family were raised. He did not have the words to describe how much has changed since rising ocean waters had taken away almost a third of the beach.
I learned of how we had to relocate my great‑great‑grandparents’ grave to higher ground twice in the last 15 years. Of how my cousins have to paddle out further to sea to catch fish, since warmer waters have destroyed much of the reef. Of how the ocean crashes so close to my uncle’s home that he had to build a new house further away.


We saw reflections of our own climate destruction in the Pacific when we shared these stories with our First Nations relatives at the edge of the Saraji mine. Murrawah Johnson and Teila Watson, both Birri Gubba and Gangulu women, made clear connections between their struggles and ours. “We don’t get to inherit our land and we don’t get to inherit our traditional roles. We are fighting a war on extinction,” Murrawah said.
Coal extraction devastated their lands and cultures – totems have disappeared, fresh water has become scarce – while the effects of using it have devastated ours. “King tide, cyclones, all the violence that has been enacted on your country and people is because of the violence that has been allowed here, to us and our country,” Teila said.
Wearing the mantle of climate leadership
This week, Australia is assuming the mantle of climate leadership as co-president and head of negotiations of this year’s UN Climate Change Conference, COP31. It will lead on deliberating the summit’s priorities as world leaders and climate negotiators descend on Fiji and Tuvalu for the pre-COP meetings.
Ironically, just days before the pre-COP began, the New South Wales Independent Planning Commission approved the largest-ever coal project the state has seen, set to emit an extra 800 million tonnes of carbon emissions. I joined the Pacific Climate Warriors and other communities in submitting about 4,000 appeals to oppose the project – yet these all fell on deaf ears.
But the fight is not yet over. The project still requires federal approval to proceed, so every promise that Australia makes while at the helm of the climate talks counts. These promises will be measured against actual decisions it makes at home: to either lock us into more decades of climate pollution, or begin shutting down coal and gas once and for all.
Pacific leaders have made it clear that countries must align their policies with the 1.5-degree warming goal, a limit that we already know will be breached within the decade. Any chance of keeping this still within reach requires an immediate end to fossil fuel expansion and concrete plans to phase out existing projects. But success will be an uphill battle if COP31’s own head of negotiations refuses to lead by example.


Australia remains the second-largest coal exporter in the world. It is one of the very few industrialised countries under the Paris Agreement’s Annex I that still has no coal phase-out plan. Since 2022, the Albanese government has approved 37 new, expanded or extended coal, oil and gas projects. It is thus unsurprising that its own mitigation policies have been rated by Climate Action Tracker as “insufficient”, even without factoring in fossil fuel exports and related expansion.
Keeping 1.5C alive
Australia must course-correct to earn the mantle it has been given, especially by Pacific nations that backed the country’s bid for the COP31 co-presidency. As a first step, the government must end all coal expansion and explicitly declare a coal phase-out date. It’s the only way to show that it’s capable of leadership that moves beyond endlessly deliberating the “if”, and starts implementing the “how” of keeping the 1.5C target alive.
The dread I felt staring down at the abyss on the edge of that coal mine months ago still exists. I carry it with me as I show up at the pre-COP to demand that leaders heed the calls of Pacific people. But it is tempered with resolve to keep our lands and communities alive. We remain steadfast in our efforts to secure an outcome that protects people everywhere and brings us back below 1.5 degrees as soon as possible.

Race to host High Seas Treaty HQ heats up as Chile reaffirms bid
When José Antonio Kast took office as Chile’s new president in March, one of his first moves was to put the brakes on plans to expand two protected marine parks – raising doubts about the country’s high-profile bid to host the headquarters of the High Seas Treaty.
But during the UN General Assembly last month, the right-wing leader reaffirmed his leftist predecessor’s ambition for Chile to host the landmark global pact, which came into effect in January and provides a legal framework to protect the waters of the high seas beyond national jurisdiction that cover about two-thirds of the world’s oceans.
Hailing the country’s “maritime vocation”, Kast’s government said the bid to host the treaty’s secretariat in the port city of Valparaíso was state policy and testament to its commitment to multilateralism.
“For the government of Chile, it is of high interest to achieve this recognition, and we will carry out all the efforts to obtain the necessary support,” Foreign Minister Francisco Pérez Mackenna was quoted as saying by local media.
Tough competition from Chinese, Belgian bids
But to garner the votes it needs, Chile must fend off competing bids by Belgium – which has proposed its well-connected capital, Brussels – and China, whose well-funded bid includes the provision of free premises in the coastal city of Xiamen and five years of free utility costs.
Parties to the treaty, formally called the Agreement on Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ), will choose the headquarters at their first summit (COP1), in New York from January 11 to January 22, 2027. They will seek consensus, falling back on a two-thirds majority in successive secret ballots.
Chile has offered to provide a restored waterside warehouse “at its own expense” as office space, pitching itself to developing countries as a Global South alternative to Europe-centred Brussels. Among richer countries, it is promoting its democratic credentials and greater transparency as an alternative to China.
Rolling back environmental safeguards at home?
While the South American country remains the top pick among environmental campaigners and other civil society groups, critics of Kast’s government say recent policy moves may make it harder for the country to garner the support it needs.
On March 12, the day after Kast took office, the Environment Ministry withdrew 43 decrees awaiting legal approval, including a push to expand the Mar de Juan Fernández and Nazca-Desventuradas marine parks – vast protected areas in Chile’s Pacific Ocean waters. Both remain under review, the ministry told Climate Home News.
The decrees also included an emission standard for coal power plants and regulations for Chile’s new biodiversity and protected areas service.
A month after holding up the decrees, Kast questioned aspects of Chile’s urban wetlands protection law, suggesting it was sometimes an unjustified obstacle to much-needed housing development, and his administration has also sought to ease the rules on salmon farming in the world’s second-largest producer.
In August, the Constitutional Court struck down the salmon farming reform after a challenge by opposition lawmakers and warnings from green groups including Greenpeace, which said it could help farms relocate into protected areas such as the Kawésqar National Reserve.
Valparaíso mayor Camila Nieto, from former leftist President Gabriel Boric’s party, backs the bid to host the High Seas Treaty, but said she hoped “the government’s support also translates into public policies consistent with the goals of protecting and conserving the oceans”.
“The decisions a country makes on environmental matters can influence international perceptions of its commitment to protecting the oceans. That is something we cannot ignore,” Nieto told Climate Home News.

China’s bid stirs concerns over data access, fishing
Chile’s past record on marine protection – it has protected 43% of its jurisdictional waters – could yet give it an edge.
“Chile deserves it for its conservation record as a state. For more than 15 years Chile has been following this path,” Liesbeth van der Meer, executive director at conservation group Oceana in Chile, told Climate Home News.
Concerns in some quarters about the rival bid by China – for example, over a potential conflict of interest due to the vast Chinese fishing industry – may also weigh in Chile’s favour, experts say.
Chinese-flagged vessels did about 30% of detected high seas fishing between 2022 and 2024, according to an Oceana analysis of Global Fishing Watch data. China also sponsors five of the International Seabed Authority’s 31 deep-sea mining exploration contracts, more than any other country.
The secretariat would host sensitive marine data, making transparency paramount, experts say.
China says hosting the secretariat in Xiamen would help make the treaty more globally representative, fostering cooperation between rich and developing countries and aiding equitable access to marine science and technology.
Wang Yi, China’s minister of foreign affairs, said in a statement that the country has “all along championed true multilateralism” and “firmly defended” UN institutions. Given Xiamen’s $38-billion ocean industry, the city lives up to the treaty’s “significance and promising future”, he added.
Meanwhile, Chile is proposing the treaty’s first high seas marine protected area for the Salas y Gómez and Nazca ridges, a chain of more than 110 seamounts stretching about 4,000 km from off Peru to Rapa Nui (Easter Island) that is rich in endemic fish and other marine species.
The ridges are “a true oasis of productivity”, said Carlos Gaymer, director of the Centre for Ecology and Sustainable Management of Oceanic Islands at Universidad Católica del Norte and co-author of a 2021 scientific review of the area.

The water is so clear that phytoplankton thrive around 200 metres down, feeding zooplankton, small fish and, up the chain, sharks and seabirds. Whales, turtles and sharks use the ridges as “a real highway” across the Pacific, Gaymer said. Parts of the Nazca ridge are likely nursery grounds for jack mackerel and swordfish.
Chile has already asked the body that regulates the industry in the area – the South Pacific Regional Fisheries Management Organisation (SPRFMO) – to close the ridges to all fishing vessels. According to Chilean data, more than 80% of fishing in the area involves Chinese vessels.
Meeting on the Chilean request in early September, SPRFMO’s scientific committee agreed only to recommend closing the area to bottom fishing. SPRFMO’s commission will take the final decision at its next meeting, in early 2027.
For Gaymer, Chile’s push to close the area to fishing should be seen as a “starting point” for the treaty proposal.
“Every time there’s a new expedition, species new to science appear,” Gaymer said. “If you don’t protect areas like these … those species simply disappear from the planet.”
