Extreme heat poses a growing threat to pregnant women and their babies, both before and after birth, the UN climate chief said on Monday, calling it “a new faultline in the global climate crisis, and one which is potentially fatal”.

Speaking on the first day of the pre-COP31 meeting in Fiji, where new research was launched on the issue, Simon Stiell warned: “This faultline must not become another deep chasm of climate-driven suffering, inequality and injustice.”

Rather than being a time of hope, he added, pregnancy is becoming “a time of anxiety, as climate impacts fill everyday life with risk”, straining health systems and threatening essentials like food, water and power – especially in poorer countries where many women work outdoors and live in informal housing far from under-equipped clinics.

In a new international survey of 1,000 maternal healthcare professionals in Australia, Brazil, India, the UK and Zimbabwe, around three-quarters reported an increase in heat-related cases or complications affecting pregnant women, as well as foetal and newborn health, over the past five years.

Nearly all respondents in the survey commissioned by Wellcome, a global charitable foundation, said they had cared for a pregnant woman or baby whose health they believed had been affected by extreme temperatures.

Researchers have linked heat exposure with preterm birth, low birth weight, stillbirth and maternal complications. For every 1 degree Celsius rise in heat exposure, the odds of preterm birth increase by around 5%, while exposure to heatwaves is associated with a 25% higher risk of obstetric complications.

“No woman should have to fear that extreme heat will harm the baby she is carrying,” said Julia Gillard, chair of Wellcome and former Australian prime minister, adding “pregnant women must not be invisible”.

Call to include mothers and midwives

Wellcome urged governments to include pregnant women, new mothers and babies in their national climate and health plans, with funded measures to protect them from extreme heat.

It also called on the World Health Organization to develop clinical guidance on heat, pregnancy and the postpartum period, alongside stronger data and surveillance on how heat exposure impacts maternal and newborn health.

The charity is backing a study in Zimbabwe and South Africa to test simple interventions such as handheld fans, reflective paint on health-facility roofs and community-led climate information systems.

The International Confederation of Midwives, which represents over 2 million midwives, is also pushing for action, asking countries to include maternal healthcare professionals in their National Adaptation Plans, and provide finance to ensure clinics have access to reliable water, power and cooling.

Chief executive Anna af Ugglas told an event on adaptation at Climate Week NYC that midwives tire more easily when working in high heat, which can lead them to make errors. They are often first responders in a crisis – and yet “too many climate and emergency plans are still developed without them”, she added.

Pacific hosts Pre-COP

The campaign to put maternal health on the climate policy agenda kicked off the proceedings in Fiji, where ministers and other attendees from around 50 countries are gathering this week to advance discussions in the run-up to the COP31 climate summit in Antalya next month.

This year’s annual UN climate conference is taking place in Türkiye which holds the COP presidency, while Australia is in charge of the negotiations – a deal worked out after a long rivalry to host COP31.

Australia is using its role to spotlight the concerns of the Pacific region to which it belongs, where low-lying island nations are under threat from sea level rise.

On Tuesday, a group of 14 government leaders – mainly from the Pacific – plus heads of international organisations including the Green Climate Fund and the Asian Development Bank will visit climate resilience projects in neighbouring Tuvalu.

Key themes for the pre-COP – a glitzier event than usual – are keeping the 1.5C global warming limit within reach despite a projected overshoot, protecting oceans and improving access to finance for small island nations and the least-developed countries.

At a press conference on Monday, Australia’s climate change and energy minister Chris Bowen flagged his country’s investments in renewables, both in Pacific nations such as Vanuatu and at home, saying this would help lower the use of diesel, fossil gas and coal in energy supplies.

Ahead of the pre-COP, Australia has been criticised by climate campaigners and some Pacific leaders for greenlighting expanded coal production on its territory.

As COP31 co-host, Australia should make its polluters pay for climate damage

Asked about Australia’s ongoing support for fossil fuels, Fiji’s climate minister Lynda Tabuya said the issue had been raised by “certain countries” at a ministerial meeting on Monday.

“There will be things that we disagree on, but we can agree to disagree – and we’re just very grateful for the support of Australia and the commitment towards renewable energy, and I think that’s the direction that we need to take, especially in the Pacific,” she added.

At pre-COP, UN climate chief warns of heat threat to mothers and babies

NADI, FIJI Sunday 4 October 2026 — As leaders and delegates gather for the Pacific Pre-COP in Fiji and Tuvalu, Greenpeace Australia Pacific is calling on the Australian government to uphold Pacific priorities on fossil fuels and climate finance, and respond to the urgency of the climate and energy crisis by accelerating the just transition away from fossil fuels. 

The Pre-COP meeting in Fiji and atoll nation Tuvalu is an important milestone on the road to the COP31 climate summit in Türkiye, where Climate and Energy Minister Chris Bowen will take the reins as President of Negotiations. But another coal mine approval in the days before the Pre-COP has left Pacific leaders and civil society exasperated at Australia’s perceived ‘double talk’ and overshadowed the start of talks.

Speaking from Nadi, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said:
“This week we must focus on why the Pre-COP is so important. We must listen to Pacific leaders and communities who are sick of Australia’s double talk on climate, and want to see the actions of the most polluting nations respond to the urgency and scale of the crisis we face.

“Every cyclone, every storm blows with the deadly force of accumulated emissions and gives a warning of what is to come. The Pacific must not become a sacrifice zone for major polluters and fossil fuel corporations.

“1.5°C remains the scientific, moral and legal temperature limit. The landmark Pacific-led ICJAO ruling is clear — continuing down the fossil fuel path, and failing to align efforts with limiting warming to 1.5°C, is a breach of our international legal obligations. Our communities, our cultures and our very existence are under threat.

“As Australia prepares to chair the upcoming COP31 talks in partnership with the Pacific, it must do much more to turn empty rhetoric into real action to end the fossil fuel chokehold.”

Also in Nadi, Dr Simon Bradshaw, COP31 Lead and climate expert at Greenpeace Australia Pacific, said: “The Pacific Pre-COP is a critical milestone on the road to COP31. The Australian government must rise to the moment with concrete plans to accelerate the global transition away from fossil fuels, and respond to communities across the region facing soaring cost of living and the escalating impacts of the climate crisis.

“This week, the Australian government must deliver more than empty rhetoric. The Prime Minister’s recent keynote address at New York Climate Week acknowledged the urgency of the climate crisis, but failed to mention its cause, fossil fuels. Just last week we saw another new coal mine approval in Australia. This is on top of the 37 fossil fuel approvals by the Albanese Government since elected, despite recognising through the Belém Declaration that returning to 1.5°C is incompatible with new coal, oil and gas.

“At the Pre-COP, words must be matched with real action to phase out fossil fuels. We can not help decarbonise the world without action at home to halt fossil fuel approvals and phase out coal and gas exports. Don’t waste this important moment to back Pacific leadership and turn commitments into real action, including an immediate end to new fossil fuel approvals, and following other nations in developing a national roadmap away from fossil fuels.”

‘Don’t waste this moment’: Pre-COP must back Pacific priorities; respond to the urgency of the climate crisis

Several major banks that helped set up the UN’s now-defunct Net-Zero Banking Alliance (NZBA) in 2021 have since continued to lend money to coal companies, a new report has revealed.

Bank of America, Barclays, Citibank, Deutsche Bank and Santander were heavily involved in the NZBA and the associated Glasgow Financial Alliance for Net Zero (GFANZ) when it was launched by Mark Carney, then a UN climate envoy and now Canada’s leader, in the run-up to the COP26 climate summit in Glasgow.

Despite their involvement, data released this week shows those banks and some others did not reduce the amount of money they lent, nor the value of their underwriting, to coal activities between 2022 and 2025. Around half of the NZBA members who were engaged in coal financing over that time increased it and half cut it, according to the report by German environmental research group Urgewald.

Ana Botín, executive chair of Santander, was a member of the GFANZ CEO principals’ group and said at the time of the NZBA launch that her Spanish bank was “proud to be part of the founding members of this new alliance and to accelerate progress towards net zero”.

Since then, the report’s data documents that Santander has provided loans and underwriting worth hundreds of millions of dollars each year to coal companies, particularly American coal-power plant operators Duke Energy and the Southern Company. Santander did not respond to a request for comment.

Urgewald’s research adjusts the value of loans and underwriting provided to coal companies based on how much of a company’s revenues come from the most polluting fossil fuel. So a hypothetical $100 million loan to German utility RWE is valued at $21 million, as 21% of RWE’s revenue is from coal.

The research does not take account of whether companies are expanding their coal business or phasing it out for greener alternatives. Some banks have said their coal clients need to put in place transition plans by a certain date. Some also say that, by a certain date, they will stop lending money to clients that get more than a set percentage of their revenue from coal.

Most companies expanding coal are in Asian nations like China, India and Indonesia and are largely financed by banks from their own countries. But there are examples of NZBA founding members supporting companies that are actively prolonging the life of their coal businesses.

For example, Glencore, a Switzerland-based multinational that gets 4% of its revenue from coal, has just won preliminary regulatory approval to keep on coal mining in Australia’s Hunter Valley until 2045. Last year, the company was supported by loans and underwriting from Bank of America, Citigroup, Santander, Barclays, Deutsche Bank, HSBC and Standard Chartered.

Good and bad news

Some NZBA founding members like Swiss giant UBS have reduced their loans and underwriting for coal companies, the data suggests. Others – like Triodos and Kenya Commercial Bank – have provided no support for coal companies since at least 2021.

Urgewald researcher Hannah O’Neill told Climate Home News that “the banking sector is not moving in one direction. There is a growing divide between banks that are tightening their coal policies and reducing their exposure, and those where coal policies remain weak or where financing continues.”

Unlike the UN’s Race to Zero campaign, with which it partnered, the NZBA did not require its members to end financing for fossil fuels like coal, leading to accusations by climate campaigners that its rules were too weak.

Despite this, after Donald Trump’s re-election as US president in November 2024, several North American banks quit the alliance and the NZBA’s requirements were diluted in April 2025. After further withdrawals, the group shut itself down in October 2025.

Globally, the Urgewald report found that many banks in the European Union, Thailand, Malaysia, India and Taiwan have reduced their coal finance since governments agreed at COP26 to phase down coal power.

But with Chinese, American, Indonesian and South Korean banks increasing their support, total bank financing for the coal industry has remained broadly the same each year since 2022. 

“Coal financing is not disappearing – but it is concentrating in banks and markets where coal policies are either missing or weak,” said Heffa Schücking, director of Urgewald.

Urgewald’s definition of coal companies includes firms and their subsidiaries that explore for, process, trade, transport and mine coal, or burn it in power plants to produce electricity, or manufacture equipment for the coal industry. It does not include companies that use coal to make cement or steel – and an adjustment is made to account for how much of the business model is coal-related.

Banks defend delays

At the time of publication, most of the banks named in the report for increasing their coal finance had not responded to requests for comment. But a spokesperson for Deutsche Bank pointed Climate Home News to its May 2026 announcement that it was delaying its requirement for existing clients to present it with transition plans and cut their coal exposure.

Instead of having to present these plans by the end of 2025, the bank has given them until the end of 2027. They will also have to ensure that their revenue share from thermal coal falls below half by then, the bank added. New clients need energy transition plans to access finance.

Deutsche Bank said at the time it was delaying its requirements because of the “increasingly complex regulatory environment as well as differing speeds of energy transition in various regions beyond what was anticipated by Deutsche Bank in 2023”.

Big banks’ lending to coal backers undermines Indonesia’s green plans 

A spokesperson for Barclays told Climate Home News: “Many companies in this report are diversified energy or mining companies. We do not provide financing to companies that generate more than 30% of revenues from thermal coal mining or power generation, and we will phase out all financing by 2035.”

The Barclays spokesperson added: “Barclays is financing an energy sector in transition, providing finance to meet current energy needs and also financing the scaling of clean energy. Over the past three years, we have facilitated more than $300 billion of sustainable and transition finance, including billions to cleaner energy projects, and invested millions into climate tech.”
