Informing people about the health risks linked to climate change is twice as likely to spur public support for government-led climate action than messages focused on economic or environmental impacts, an international study has found.
Based on a survey of around 30,000 respondents in Brazil, India, Japan and South Africa carried out in late 2025, the report published this month by the Climate Opinion Research Exchange (CORE) and the Wellcome Trust reveals strong public support for climate action.
Over 80% of respondents said they are concerned about the impacts from climate change, the survey shows. A majority also back government measures to prevent public health impacts associated with the climate crisis.
“Humanitarian emergencies” are already increasing around the world due to human-caused rising temperatures, according to the World Health Organization (WHO). More than a third of the global population is exposed to climate threats like wildfires, extreme heatwaves, and tropical storms and floods, it says. These threats are amplified by human-caused greenhouse gas emissions.
Dustin Gilbreath, a researcher at CORE and one of the study’s lead authors, said that communicating these risks to the general public can be an effective way to inspire climate action, given that health is a basic concern for everyone across the political spectrum.
“If you suddenly find out that climate change is hurting your health and your children’s health, more people are rightfully more open to that argument,” he said. “At the end of the day, we all care about our health, regardless of our political inclinations.”
At COP28 in Dubai, more than 150 countries issued a declaration “expressing grave concern” over climate-fuelled health impacts, and pledged to strengthen policies that can cut carbon emissions and benefit people’s health in the process – for example by reducing air pollution from cars or factories.
More than 80 nations also endorsed a plan to improve the health sector’s resilience to climate impacts at the COP30 summit in Belém last year. The initiative received $300 million in philanthropic backing to help governments identify health risks, improve monitoring of climate threats, and strengthen emergency responses to extreme weather events, among other measures.
Despite these pledges, health has not been at the top of the agenda at key meetings like the recent conference on Transitioning Away from Fossil Fuels in Santa Marta, Colombia. The Global Climate and Health Alliance, which represents 250 health organisations, said leaders in Santa Marta “did not address the importance of protecting people’s health”.
Health priorities vary by country
To gain insights into people’s attitudes towards climate change, researchers tested 16 different messages with respondents in a survey-based randomised trial, comparing their reactions to messages on health-related issues like extreme heat or infectious diseases, and non-health issues related to jobs, the cost of living or nature. They also compared the participants’ reactions to a control group in each country who were not shown any messages.
While a majority were concerned about the health impacts from climate change, the types of effects that caused the strongest reaction varied depending on the country.
In South Africa, for example, public opinion resonated very strongly with messages related to children’s health. Messages linked to food and water insecurity also chimed well with South Africans, who recognised widely that climate change is a threat to people’s health.
The study’s authors say that context is key to understanding the effectiveness of messaging. South Africa, for example, has a young population with a median age of 28 years – compared to Europe’s 45 years – and has faced severe water shortages in cities like Cape Town, which was close to a “Day Zero” event after a major drought between 2016 and 2018. This term refers to the threat of municipal services running out of water.
Brazilians, on the other hand, reacted strongly to messages related to mental health impacts, which performed better than other messages by a wide margin. These types of impacts include, for example, severe anxiety or stress caused by losses after a flood or hurricane. In total, 93% of Brazilians said they are somewhat, or very concerned about, climate change.
Neha Dewan, senior advisor at the Wellcome Trust, a health-focused charitable foundation, said this finding was “counter-intuitive”, given that mental health is often seen as less of a priority. “This really helps us see what’s unexpected and find newer ways of reaching different audiences,” she added.
In Japan, extreme heat was the top-performing message, while in India it was air pollution and access to healthcare. Dewan said the India results confirm what people already discuss informally. “Every time I’m back home seeing family in India, everybody talks about air pollution. It’s the living, breathing reality.”

Commission urges government action
Dewan said she hoped the findings “go beyond journals” and instead can “actually end up in society”, with the goal of helping “empower policy conversations”. Respondents across countries firmly supported government action to prevent or protect them from the health impacts of a warming climate.
In Brazil and South Africa, emissions-cutting measures such as building solar capacity to produce clean energy had more than 90% support, while in India and Japan respondents strongly backed adaptation measures like investments in allowing air-conditioned public buildings to be used during heatwaves.
Ahead of the May 18-22 World Health Assembly, the WHO’s highest decision-making body, experts highlighted the urgency of implementing such steps. The Pan-European Commission on Climate and Health, composed of former global leaders and chaired by former Icelandic Prime Minister Katrín Jakobsdóttir, called on governments “to take forward climate action that delivers benefits for human health”.
The commission issued a 17-point plan to address health impacts from the climate crisis, which includes declaring climate change a “global health emergency” and bringing it to the agenda of national security councils, as well as scaling up “climate-health investment”.
“The climate crisis is a threat to our safety and security, social cohesion, human rights and health,” Jakobsdóttir said in a statement. “Climate action is not merely a necessity. It is a high-return investment for a more just and resilient society.”
The Wellcome Trust’s Dewan said the survey provides data-backed insights showing policymakers that the public supports stronger action on climate change. “It’s beyond anecdotal now. Here’s the evidence telling us that constituents really care about these issues,” she said.
Fresh approach to climate dialogue
The findings of the study suggest that a focus on health could become an effective way for policymakers and activists to draw in new audiences and inspire action on climate change, the authors of the report said.
“The cost-of-living message or the jobs and economy messages have been used over and over again. People have been saying this for a good decade. Probably the people that are convinced by this already would’ve said they’re concerned about climate change,” said Gilbreath of CORE.
He added that the health angle is probably a newer approach for some audiences, but the hypothesis based on the survey findings would need to be tested with further research. He also noted that economic messages still serve a purpose in some contexts and should not be abandoned.
Dewan said health messaging could become a “missing piece” in climate communications. “Health is personal, proximal, relevant and – politically speaking – it’s depolarising,” she said.
“It gives us an inroad to talk about climate differently in a way that feels very relevant,” she explained. “It’s about figuring out what’s the next insight to unpack and make these communications and engagements even stronger and relevant.”

Will new UK PM’s green measures at home cause climate finance pain overseas?
Britain’s new prime minister announced in his first week that he will cut the cost of public transport and electricity, making lower-emission technologies like bus travel, electric vehicles and heat pumps more affordable for voters. But some of the funding for those policies will come from the budget for international climate finance, the government has said, raising concerns about fairness.
Former Manchester Mayor Andy Burnham took over from Keir Starmer as Labour Party leader and prime minister on Monday, appointing climate advocates Ed Miliband as foreign and development minister and Miatta Fahnbulleh as climate and energy minister.
On Tuesday, Burnham said his government would cut the value added tax (VAT) households and some small businesses pay on their electricity bills from 5% to zero from October 1, saving households £45 ($60) a year.
On Wednesday, he said the maximum fare bus companies in England can charge for a single journey will be reduced from £3 ($4) to £2 ($2.67) from January 1, 2027. The government said the subsidies to achieve this would be mostly funded by switching money set aside for overseas climate finance projects from grants to loans. It did not give further information in its announcement, while the UK’s transport minister told Sky News the plan is still being worked out.
The floated changes to the climate finance budget were immediately criticised by groups working on climate justice for developing countries, including Bond, the UK network for NGOs, which described the decision as “disappointing”.
“Robbing Peter to pay Paul is not the answer and pitches marginalised communities in the UK against marginalised communities in lower-income and climate-vulnerable countries,” BOND CEO Romilly Greenhill said in a statement. “Climate finance must not worsen the debt burden of countries that are already suffering the worst – and most costly – impacts of a climate crisis they did not cause.”
Hunt for money
Burnham promoted both policies as measures to combat the rising cost of living and “give people breathing space”, with climate campaigners and industry groups noting they are also likely to reduce the UK’s climate-heating emissions by encouraging bus travel and the use of electric vehicles and heating.
But thorny questions remain over how the policies will be paid for. The government said Tuesday’s VAT cut for electricity would be funded by scrapping the previous government’s digital ID programme, but Darren Jones, a former minister involved with that policy, said it had been “unfunded” – a statement that dominated media coverage.
A day later, the government said the new bus fare cap would cost £454 million ($606m). Transport minister Heidi Alexander told Sky News that £54 million would be taken from an under-spend in the budget of the Department for Energy Security and Net Zero (DESNZ) and £400 million would come from changing unspecified international climate finance from grants to loans. The details “still need to be worked through”, she said, adding that the government “had wanted to make an announcement today”.
Mohamed Adow, director of Nairobi-based think-tank Power Shift Africa, said “climate finance was never meant to be a pot of money that governments raid when they need to pay for domestic spending”.
DESNZ had not responded to a request for comment at the time of publication. “We’re not wanting to fleece anyone here, and we actually want to maximise the development potential of this money that is available,” minister Alexander said in her TV interview.

Aside from the controversy over their funding, the policies themselves were widely welcomed by climate campaigners. Jess Ralston, energy lead at the Energy and Climate Intelligence Unit (ECIU), said the tax cut on electricity bills “could help households to switch to electric heat pumps, protecting UK homes from becoming ever more exposed to the whims of Putin and Trump when turning on their gas boiler”.
The last few months have seen global momentum build behind electrification, spurred by the US-Iran war disrupting oil and gas supplies and driving up prices. The Turkish and Australian COP31 presidencies have announced a global target to boost electrification, backed by the European Union, Canada, Philippines, UK and others.
Campaigners call for lower power prices
While reaction to the VAT cut was supportive, some questioned whether £45 a year of savings per household is enough and called for more measures to cut electricity bills.
Friends of the Earth’s energy lead Imogen Dow said those on the lowest incomes should be given cheaper electricity through a “social tariff” and the Institute for Public Policy Research (IPPR) think-tank – which is close to the Labour Party – said levies on energy bills should be shifted to general taxation.
Matthew Paterson, a politics professor at Manchester University, told Climate Home News that the most effective way to reduce electricity bills is to take on the UK’s private electricity companies, while consumer-oriented measures like the VAT cut are “tinkering around the edges”.
Jarrod Birch, head of policy and public affairs for the EV charging industry association Charge UK, said that while the policy would make home-charging cheaper, people who charge their vehicles at public points will still have to pay 20% VAT. The UK’s tax authority is fighting a court ruling that ordered it to reduce the tax motorists pay on public chargers to the current household rate of 5%.
Further measures will be the responsibility of Secretary of State for Energy Security and Net Zero Miatta Fahnbulleh, who is relatively new to politics after a career at left-wing, pro-climate think tanks the IPPR and the New Economics Foundation.

Michael Jacobs, political economy professor at Sheffield University and former adviser to UK Labour prime minister Gordon Brown, said Fahnbulleh would be a “climate advocate” who would continue the “progressive climate agenda” of her predecessor Ed Miliband.
“She’s a very creative policy wonk so I expect there to be lots of policy innovation under her,” he said, “I think she will be looking at new ways to encourage take-up of heat pumps and domestic batteries.”
Aid budget in Miliband’s hands
Despite reports he could be made finance minister, Miliband has been appointed Secretary of State for Foreign and Commonwealth Affairs. Miliband has attended many climate COP meetings over several decades, most recently representing the UK at COP29 and COP30, and has been targeted by the right-wing media for his support for climate action and opposition to new oil and gas drilling in the UK’s part of the North Sea.
In his new role, Miliband will be responsible for the UK’s overseas aid budget including its international climate finance, which the Starmer government had slashed to fund increases in defence spending.
UK cuts support for climate action abroad to fund military instead
Jacobs said he expected Miliband to prioritise climate and development in the UK’s foreign policy and to push Burnham and new finance minister John Healey to reverse Starmer’s aid cuts.
But there are fears Healey could try to cut the aid budget further to fund the military. Healey was a surprise pick for Chancellor of the Exchequer and grabbed headlines when he resigned as Starmer’s defence minister in June over what he saw as insufficient defence spending.

Greenpeace launches legal challenge against Australia’s biggest meat company
AMSTERDAM, Netherlands, 22 July 2026 – Greenpeace Netherlands has launched legal proceedings against a multi-billion-dollar global expansion plan by the biggest meat producer in Australia, JBS, in an escalation of climate litigation against the livestock industry.
Greenpeace petitioned a Dutch court to compel the meat giant to disclose information in order to challenge its business policies in court, including a US$6 billion global expansion, for which almost half is earmarked for Nigeria.
Elizabeth Atieno, Food Campaigner at Greenpeace Africa, said: “JBS’ meat empire expanded hand-in-glove with Amazon destruction, colossal emissions, human rights and corruption scandals, all with barely a semblance of transparency. This is the business model it wants to export to sub-Saharan Africa. JBS promises food security, but its expansion in Nigeria risks causing irreversible environmental damage and the displacement of smallholder farmers to line the pockets of wealthy global elites.
“Nigerians know well from the legacy of companies like Shell the destructive impact wrought by unchecked corporate power. As Greenpeace Africa has argued before the African Court of Human Rights, states with jurisdiction over multinationals must hold those corporate actors accountable – wherever they operate in the world. We welcome this bold legal action: the Netherlands and other European states must not be safe havens for corporations like JBS seeking to evade their responsibilities.”
In light of JBS’ longstanding failure to publish accurate and reliable information on its climate, nature and human rights impacts or its expansion plans, Greenpeace Netherlands views accessing this data as a necessary precursor to formal litigation in order to support its case. The case has the potential to be the first climate litigation of this scale against the livestock industry. This could set a major precedent for future legal challenges against the industrial agriculture sector, a major source of global emissions, particularly of methane, a potent greenhouse gas, responsible for 0.5°C of warming since the Industrial Revolution.[1]
JBS, via its subsidiary JBS Foods Australia, is the largest meat and food processing company in Australia. With a weekly processing capacity of over 50,000 cattle, it accounts for almost a quarter of all beef processing in the country, as well as a significant presence in the lamb, pork and farmed fish markets. [2] In 2022, ABC’s Four Corners accused the company of ‘repeatedly failing to protect its workers from horrific injuries.’ [3]
Marieke Vellekoop, Executive Director at Greenpeace Netherlands, said “In a month where JBS has thrown its flagship environmental commitments onto the scrap heap, JBS’ disdain for basic transparency only adds to the impression that this meat giant has something to hide and is desperate to prevent its expansion plans from going public. We were hoping we wouldn’t have to trouble a judge with this matter, but JBS has left us no choice but to seek our right to information through the Dutch courts.
“JBS appears to believe that despite moving to the Netherlands, our rules do not apply to it. This legal action aims to prove it wrong – and lay the ground for a first major climate and nature lawsuit against the dangerous expansion of the global meat industry.“
At the centre of the dispute is JBS’ planned US$ 2.5 billion investment in industrial livestock production in Nigeria.[2] Civil society groups in Nigeria have raised urgent warnings that the aggressive expansion will threaten local food security, drive regional instability, and accelerate ecological degradation. There is no available evidence that JBS has conducted any impact assessments or community consultations in Nigeria, and local efforts to gather more information via Freedom of Information requests have reportedly been ignored.[3]
The escalation to the courts follows the refusal of JBS, the world’s largest meat company, to comply with a formal disclosure demand delivered by Greenpeace Netherlands in April. The environmental group is utilising new Dutch legislation, which grants parties with a legitimate interest the right to demand access to specific corporate data necessary to build litigation against Dutch companies.[4]
Greenpeace Netherlands’ lawyers allege that JBS’ historic business practices and future expansion plans are inconsistent with the company’s climate and biodiversity obligations and represent a breach of its Dutch duty of care, which requires companies to act in line with international human rights law.[5]
If the court rules in favor of Greenpeace Netherlands, it is entitled to seek the required information in the form of documents and from senior JBS figures under oath, raising the prospect of the Batista brothers being forced to testify in Dutch court. JBS reincorporated as a Dutch entity (JBS N.V.) last year to facilitate a dual listing on the New York Stock Exchange.
In April, JBS was forced to temporarily suspend its first annual general meeting since moving its headquarters to Amsterdam after it was disrupted by dozens of Greenpeace Netherlands activists.
Last week, JBS scrapped two flagship commitments to reach Net Zero emissions by 2040 and eradicate deforestation from its supply chain. It also removed any explicit reference to Indigenous lands from all of its current policies. Greenpeace Netherlands is concerned this indicates JBS is seeking to expand unconstrained by the climate, nature and human rights impacts of its business.

Notes:
[1] The livestock sector is estimated to be responsible for 31% of global methane emissions (more than oil and gas operations). In comparison to CO2, methane is shorter lived (around 12 years) but has a much stronger ability to trap heat in the atmosphere over its lifetime: it has approximately 80 times more climate impact than CO2 when measured over 20 years. This means that changes in methane emissions have a more rapid effect on the climate than changes in CO2. See Greenpeace Netherlands letter to JBS dated 30 April 2026.

“Next year is too late for regulations”: Beetaloo Energy’s 2GW gas-powered AI data centre a “disaster proposal” destined to cause climate chaos
SYDNEY, Wednesday 22 July 2026 — Beetaloo Energy has secured land from the NT Government for a massive $40 billion “hyperscale” AI data centre near Darwin, which would be powered by 2 gigawatts (GW) of gas power fracked directly from the Beetaloo basin, prompting calls from Greenpeace for urgent federal legislation.
The proposal marks a dangerous escalation in the AI data centre industry’s expansion, which threatens to entrench fossil fuel infrastructure for decades and put immense pressure on the region’s fragile water resources — while continuing to be unregulated.
Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “This disaster proposal for a 2GW gas-powered AI data centre in the NT is a shocking example of the unchecked expansion of hyperscale data centres in Australia. It is also, critically, more evidence for the urgent need for a moratorium on all new data centres until strong, binding regulations are put in place to protect our communities and climate.
“This proposal mirrors the frenzied, unchecked expansion currently wreaking havoc on communities in the US. We are seeing cowboy data centre operators treat Australia like a playground, steam-rolling ahead with projects that would lock down precious water resources and spike emissions, despite the overwhelming community opposition.
“Every day, more councils, communities and environmental groups are joining Greenpeace’s call for a moratorium on data centres, yet as of today there is still no system of safeguards or rules in place to regulate these companies.
“While Beetaloo Energy and the NT Government prepare to bulldoze ahead with this climate and water disaster, the Prime Minister is asleep at the wheel, promising to legislate a vague set of standards next year.
“Next year is too late, and anything less than mandating data centres cover their own energy demand, and then some, with new renewable energy is not enough.”
