The Brazilian COP30 presidency has published a “Baku to Belém roadmap” on how climate finance could be scaled up to “at least $1.3tn” a year by 2035.
The idea for the roadmap was a late addition to the outcome of COP29 last year, following disappointment over the formal $300bn-per-year climate-finance goal agreed in Baku.
The new document, published ahead of the UN climate talks in Belém, Brazil, says it is not designed to create new financing schemes or mechanisms.
Instead, the roadmap says it provides a “coherent reference framework on existing initiatives, concepts and leverage points to facilitate all actors coming together to scale up climate finance in the short to medium term”.
It details suggested actions across grants, concessional finance, private finance, climate portfolios, capital flows and more, designed to drive up climate finance over the next decade.
Despite geopolitical uncertainty, there is hope that this roadmap can lay out a pathway to the “trillions” in climate finance that developing countries say they need to meet their climate targets.
Countries have divergent views on how to get there, but some notable trends have emerged from the roadmap, which was spearheaded by the Azerbaijani and Brazilian COP presidencies.
Below, Carbon Brief details what the Baku to Belém roadmap is, why it was launched and what the key points within it are.

Why was the ‘Baku to Belém roadmap’ launched?
A mounting body of evidence shows that developing countries will need trillions of dollars in the coming years if they are to achieve their climate goals.
While much of this finance will likely be sourced domestically within those countries, a large slice is expected to come from international actors.
This climate finance is part of the “grand bargain” at the heart of the Paris Agreement, whereby developing countries agree to set more ambitious climate plans if they receive financial support from developed countries.
Ahead of COP29, developing countries hoped that the post-2025 climate finance target – known as the new collective quantified goal (NCQG) – would reflect their full “needs and priorities”, as set out in the Paris Agreement.
They also pushed for developed-country parties such as the EU, the US and Japan to contribute a large portion of this finance, preferably on favourable terms such as grants.
They were left largely disappointed, with a final target that fell well short of what many developing countries had been proposing.
The central target agreed at COP29 was “at least” $300bn a year by 2035, with an expectation that developed countries would “take the lead” in providing these funds from “a wide variety of sources”, including private finance.
This goal – which was effectively the successor to the previous $100bn-per-year target – was far short of what developing countries had wanted. However, another key part of the text agreed in Baku alludes to their ambitions, with a loose request that “all actors” scale up finance to at least $1.3tn per year by 2035:
“[The COP] calls on all actors to work together to enable the scaling up of financing to developing country parties for climate action from all public and private sources to at least $1.3tn per year by 2035.”
In contrast to the $300bn target, this $1.3tn figure, which first appeared in a proposal by the African Group in 2021, reflects developing-country demands and needs. It also aligns with influential analysis of developing-country needs by the Independent High-Level Expert Group on Climate Finance (IHLEG).
Yet, this part of the text lacked binding language and detail on who precisely would be responsible for providing these funds. It has therefore been described by civil-society groups as more of an aspirational “call to action” than a target.
(“Calls on” is the weakest form of words in which UN legal texts can make a request.)
However, the COP29 text contained another relevant decision, added as negotiations drew to a close. It mentioned a “Baku to Belém roadmap to $1.3tn” – a report that could flesh out ways to scale up finance further and help developing countries achieve their climate targets.

The Azerbaijani COP29 presidency and the incoming Brazilian presidency were tasked with assembling this roadmap ahead of COP30 in 2025.
In the months that followed, the presidencies engaged with governments, civil-society groups, businesses and other relevant actors. They gathered information to build a “library of knowledge and best practices”, which could boost climate finance for developing countries.
What is the goal of the roadmap?
The roadmap comes at a difficult time for climate finance, with a particularly “bleak” outlook for public funding from developed countries. Major donors – particularly the US – have made large cuts to their aid budgets, threatening climate spending overseas.
At the same time, private investment has also faltered, with successive economic shocks raising the cost of capital for clean-energy projects in developing countries.
For years, finance experts and development leaders have talked of a “billions to trillions” agenda, suggesting that public money could help to “mobilise” trillions of dollars of private investments that could be used to build low-carbon infrastructure in the global south.
Yet, the “billions to trillions” concept has also faced growing scrutiny, with even the World Bank chief economist Indermit Gill branding it “a fantasy”. Critics have highlighted wider issues constraining developing countries, such as high levels of debt.
The NCQG text from COP29 set out the roadmap’s overarching goal of scaling up annual climate finance to $1.3tn, through means including “grants, concessional and non-debt-creating instruments, and measures to create fiscal space”.
On the current trajectory, financial sources potentially covered by the target could hit around $427bn for developing countries a year by 2035, less than a third of the goal, according to analysis by the thinktank NRDC.
Achieving $1.3tn of finance relies on what one report calls “yet-to-be-defined mechanisms”, which go beyond the ones covered by the $300bn target.
Countries and other relevant parties were asked by the presidencies for their views on “short-term” – actions by 2028 and “medium-to-long term” actions beyond 2028 that could ramp up finance further. They were asked about new sources of finance and thoughts on scaling up adaptation finance, in particular.
There have already been numerous ideas and programmes put forward for scaling up international climate finance. These include G20-led reforms of the multilateral development banks (MDBs), this year’s International Conference on Financing for Development, as well as UN sovereign debt restructuring efforts.
Accordingly, the Baku to Belém roadmap was also given a remit to “tak[e] into account relevant multilateral initiatives as appropriate”. Parties were also asked for suggestions of organisations and initiatives that should be involved.
Rebecca Thissen from Climate Action Network (CAN) International tells Carbon Brief:
“The roadmap could support the UNFCCC to be sending strong signals to the international community…But also using the convening power that the UNFCCC could have, so bringing those different actors to the table in a more structured and predictable way.”
What are different countries’ views on climate finance?
There were over 227 submissions into the Baku to Belém roadmap, including 38 from countries and party groupings. The remainder came mainly from NGOs, businesses, financial experts and researchers, as shown in the figure below.

The submissions partly reflect what the thinktank C2ES describes as the “pockmarked baggage of the climate finance negotiations”, with many parties demonstrating the same entrenched, often opposing views on climate finance that they have held for decades.
Carbon Brief has captured the submissions by countries and party groupings in the interactive table below, comparing their views on key issues.
There is broad agreement among countries that the roadmap should not reopen the NCQG discussions or involve a new, negotiated outcome at COP30.
However, some parties still call for more accountability in achieving the existing goals.
Latin American countries within the AILAC grouping call for the roadmap to “define concrete milestones for scaling up climate finance”. Egypt goes further, proposing that developed countries alone commit “at least $150bn annually in public concessional finance by 2028”, mainly as grants.
A key divergence in submissions is on which governments and institutions, precisely, should be responsible for scaling finance up to $1.3tn.
Several developing-country groups stress the importance of centring developed countries as the primary contributors, referencing Article 9.1 of the Paris Agreement.
The Like-Minded Developing Countries (LMDCs) group, which includes India, China and Saudi Arabia, states that “the roadmap must place Article 9.1 as its central pillar”. The G77 and China – a group representing all developing countries – stresses the “additional role developed countries will play in the context of Article 9.1, which is additional to the $300bn”.
Meanwhile, many developed countries focus on what Canada refers to as “a necessary broadening of climate finance” within the roadmap. In practice, this often amounts to a greater push for private finance, as well as “innovative” new sources such as global levies.
While developing countries do not often outright oppose such sources, some of them propose tighter limits. For example, China says “purely commercial investment flows should not be included” in the $1.3tn, which should only count funds “mobilised through public interventions”.
A related dispute centres on the roadmap’s scope, with the EU suggesting it should “extend beyond the UNFCCC framework”.
Parties such as India reject the idea of involving other multilateral fora, such as the G20. This would involve moving beyond the UN climate process, where developed countries have traditionally been the ones responsible for channelling climate finance.
The submissions also show notable differences among developing-country groupings. On the topic of defining what should be counted as “climate finance”, the Alliance of Small Island States (AOSIS) opposes the inclusion of funding for fossil-fuel projects, while the Arab Group says it does not support “any exclusionary criteria”.
There is coalescence between parties around other issues, albeit with various subtle differences.
Areas of broad agreement include the importance of more funding for climate adaptation, dealing with “barriers” to funding in developing countries and improving the transparency of climate-finance provision.
The roadmap details some of the potential sources of finance identified within the submissions.
This includes direct budget contributions, which the submissions suggest could generate an additional $197bn in financing; improved rechanneling and new issuances of special drawing rights ($100-500bn per year); carbon pricing ($20-4,900bn, dependent on rate and geographies); and fees on aviation or maritime transport($4-223bn).
Additionally, a range of taxes were identified as candidates for raising new climate finance. These include taxes on specific goods such as luxury fashion, technology and military goods ($34-112bn), financial transactions taxes ($105-327bn), minimum corporate taxes ($165-540bn) and wealth taxes ($200-1,364bn).
In a statement, Rebecca Newsom, global political expert at Greenpeace International, said:
“It’s notable that the roadmap recognises new taxes and levies as key to unlocking public climate finance. Given reported profits from just five international oil and gas giants over the last decade reached almost $800bn, taxing fossil fuel corporations is clearly a huge opportunity to overcome national fiscal constraints.
“The roadmap’s recognition that the UN tax convention provides an opportunity to raise new sources of concessional climate finance is also highly welcome, and is an opportunity governments must now seize.”
What are the solutions that the roadmap has identified?
The roadmap sets out “five action fronts” for reaching $1.3tn by 2035.
These are designed to “help deliver on the at-least-$1.3tn aspiration by strengthening supply, making demand more strategic, and accelerating access and transparency”.
The report titles these five action fronts as “replenishing, rebalancing, rechanneling, revamping and reshaping”.
Within each of these, the roadmap lays out key points to help “transform scientific warning into a global blueprint for cooperation and tangible results”.
The first, “replenishing”, refers to grants, concessional finance and low-cost capital, including multilateral climate funds and MDBs.
It notes that there is a “growing role” for MDBs in advancing climate action, as well as a need for developed countries to achieve “manyfold increases in the delivery of grants and concessional climate finance, including through bilateral and multilateral channels”.
Access to grants and concessional finance is a key enabling factor for an “efficient” flow of public funding, the roadmap notes.
The roadmap calls for coordination in the international finance system, bilateral finance that is concessional and low-cost, multilateral climate funds, innovative sources of concessional finance with simplified access pathways and more.
This coordination could be key, with Sarah Colenbrander, director of ODI’s climate and sustainability programme, telling Carbon Brief:
“The bigger risk is probably that some countries will allocate their climate finance differently, so that they can report more money going out the door without a commensurate increase in fiscal effort. For example, they might shift from grants to concessional loans, and from concessional loans to market-rate loans. If the money will be repaid, there is less lift for taxpayers at home.
“Alternatively, countries might focus on using public finance to mobilise private finance that can also count towards the $300bn goal. Private finance has a very important role to play in both mitigation and adaptation, but it is very unlikely to meet the needs of the most vulnerable communities, given their high adaptation investment needs and very limited ability to pay.”
In particular, the roadmap suggests MDBs “intensify their engagement on climate finance through a strategic approach that recognises and amplifies their catalytic role in providing and mobilising capital”.
Second, “rebalancing” refers to fiscal space and debt sustainability. The roadmap calls on creditor countries, the International Monetary Fund (IMF) and MDBs to work together to “alleviate onerous debt burdens faced by developing countries”.
The roadmap notes that external debt servicing costs of developing countries have more than doubled since 2014, to $1.7tn per year in 2023.
Developing countries’ net interest payments on public debt reached $921bn in 2024, a 10% increase compared to 2023, it adds.
The roadmap notes the need to “remove barriers and address disenablers faced by developing countries in financing climate action”. It adds that developing countries face at least two- to four-times the borrowing costs of developed countries.
It points to a number of “promising” solutions already being implemented, such as climate-resilient debt clauses and “debt-for-climate swaps” and debt restructuring.
In particular, MDBs, the IMF, UN agencies and regional UN economic commissions could work together to create a “one-stop shop” for assistance in these areas, the roadmap says.
Third, “rechannelling” refers to “transformative” private finance and affordable cost of capital.
It notes that mobilisation of private finance has been “stubborn to scale”: The level of private finance leveraged by official development interventions has grown by 7% per year from 2016 to 2019 and then 16% per year from 2020 to 2023, to reach $46bn.
The roadmap says that “blended finance” can play a role in scaling up climate finance and that private finance for the implementation of “nationally determined contributions” to cutting global emissions (NDCs) and national adaptation plans (NAPs) has “significant potential for growth”.
“Innovative instruments” are listed as a key approach to improving private finance, including “catalytic equity”, guarantees, foreign exchange risk management, securitisation platforms and more.
To support this, the roadmap calls for target-setting and data transparency, along with increasing, coordinating and harmonising guarantee offerings and channelling concessional finance into long-term foreign exchange hedging facilities, along with other actions.
Relying heavily on private finance could pose a risk, Jan Kowalzig, senior policy adviser for climate at Oxfam Germany, tells Carbon Brief, adding:
“The much larger problem, however, is the plan to massively rely on private finance in the future. While private finance has a key role to play to transform economies, [it] cannot replace much-needed public finance, especially for adaptation and for responding to loss and damage.
“Interventions in these sectors often do not generate return to satisfy investors’ expectations. Forcing projects to become profitable can come at great social cost for frontline communities struggling to survive in the worsening climate crisis.”
The roadmap suggests financial institutions move towards “originate-to-distribute” and “originate-to-share” business models, support the development of climate-aligned domestic financial systems and expand investor bases and diverse sources of capital, amongst other proposals.
Fourth is “revamping”, referring to capacity and coordination for scaled climate portfolios. This “demands institutions to manage risks locally, develop project pipelines, ensure country ownership and track progress and impact”.
It notes that “whole-of-government” approaches to the transition can be strengthened, with NDCs and NAPs integrated throughout national investment strategies. Additionally, it points to country-led coordination or platforms as a route for improving investment.
The roadmap suggests readiness support and project preparation as routes to “revamp” climate finance, alongside support to scale, coordinate and tailor capacity building, the development of country platforms and the provision of “predictable and flexible support for investment frameworks”.
The final “R” is “reshaping”, focused on systems and structures for capital flows. It highlights a number of barriers that still remain for capital flows through developing countries, including outdated clauses in investment treaties.
It recommends prudential regulation, interoperability of taxonomies, climate disclosure frameworks and investment treaties, as key actions to support the reshaping of capital flows.
Additionally, the roadmap suggests that credit rating agencies further refine their methodologies, that jurisdictions adopt voluntary disclosure of climate-related financial risks of financial institutions and that climate stress-test requirements are gradually embedded in supervisory reviews and bank risk management.
Beyond the “five [finance] action fronts”, the roadmap sets out five thematic areas, noting that “where and how finance is directed” matters.
These are: adaptation and loss and damage; clean-energy access and transitions; nature and supporting its guardians; agriculture and food systems; and just transitions.
Within each, it sets out some of the key challenges and suggests routes for financial support.
What happens next?
The Baku to Belem roadmap is not a formal part of COP30 negotiations, but there will be a major launch event at the summit.
Beyond that, the final section of the roadmap sets out that this is the “beginning [of] the journey”. It and details suggested short-term contributions (2026-2028), to serve as “initial, practical steps to inform and guide the early implementation of the roadmap”.
This includes the Azerbaijani and Brazilian presidencies convening an expert group tasked with refining data and developing “concrete financing pathways” to get to $1.3bn in 2035. This will build on the action fronts set out in the roadmap, with the first such report due by October 2026.
Throughout 2026, the presidencies will convene dialogue sessions with parties and stakeholders to discuss how to progress the action fronts over the medium to long term.
The roadmap suggests that to improve predictability, developed countries “could consider” working together on a delivery plan to outline how they expect to achieve the at-least $300bn goal by 2030, as well as other elements of the NCQG.
Additional suggestions in the roadmap are listed in the table below.
(Notably, almost all of these suggestions are made using loose, voluntary language. For example, the roadmap says that developed countries “could” create a delivery plan for their NCQG pathways.)

COP29 president Mukhtar Babayev and COP30 president André Aranha Corrêa do Lago conclude in the foreword of the report that while the $1.3bn “journey” is beginning amid “turbulent times”, they are confident that “technological and financial solutions exist”. They add:
“Communities and cities are acting. Families and workers are ready to roll up their sleeves and deliver more action. If resources are strategically redirected and deployed effectively – and if the international financial architecture is reset to fulfil its original purpose of ensuring decent prospects for life – the $1.3tn goal will be an achievable global investment in our present and our future. We are optimistic.”

Permitting reform: A major key to cutting climate pollution
Permitting reform: A major key to cutting climate pollution
By Dana Nuccitelli, CCL Research Coordinator
Permitting reform has emerged as the biggest and most important clean energy and climate policy area in the 119th Congress (2025-2026).
To make sure every CCL volunteer understands the opportunities and challenges ahead, CCL Vice President of Government Affairs Jennifer Tyler and I recently provided two trainings about the basics of permitting reform and understanding the permitting reform landscape.
These first introductory trainings set the stage for the rest of an ongoing series, which will delve into the details of several key permitting reform topics that CCL is engaging on. Read on for a recap of the first two trainings and a preview of coming attractions.
Permitting reform basics
Before diving into the permitting reform deep end, we need to first understand the fundamentals of the topic: what is “permitting”? What problems are we trying to solve with permitting reform? Why is it a key climate solution?
In short, a permit is a legal authorization issued by a government agency (federal and/or state and/or local) that allows a specific activity or project to proceed under certain defined conditions. The permitting process ensures that public health, safety, and the environment are protected during the construction and operation of the project.
But the permitting process can take a long time, and in some cases it’s taking so long that it’s unduly slowing down the clean energy transition. “Permitting reform” seeks to make the process more efficient while still ensuring that public health, safety, and the environment are protected.
There are a lot of factors involved in the permitting reform process, including environmental laws, limitations on lawsuits, and measures to expedite the building of electrical transmission lines that are key for expanding the capacity of America’s aging electrical grid in order to allow us to connect more clean energy and meet our energy affordability and security and climate needs.
But if we can succeed in passing a good, comprehensive permitting reform package through Congress, it could unlock enough climate pollution reductions to offset what we lost from this year’s rollback of the Inflation Reduction Act’s clean energy investments. Permitting reform is the big climate policy in the current session of Congress.
Understanding the permitting reform landscape
In the second training of this series, we sought to understand the players and the politics in the permitting reform space, learn about the challenges involved, and explore CCL’s framework and approach for weighing in on this policy topic.
Permitting reform has split some traditional alliances along two differing theories about how to best address climate change. Some groups with a theory of change relying on using permitting and lawsuits to slow and stop fossil fuel infrastructure are least likely to be supportive of a permitting reform effort. Groups like CCL that recognize the importance of quickly building lots of clean, affordable energy infrastructure are more supportive of permitting reform measures.
The subject has created some strange bedfellows, because clean energy and fossil fuel companies and organizations all want efficient permitting for their projects, and hence all tend to support permitting reform. For CCL, the key question is whether a comprehensive permitting reform package will be a net benefit to clean energy or the climate — and that’s what we’re working toward.
The two major political parties also have different priorities when it comes to permitting reform. Republicans tend to view it through a lens of reducing government red tape, ensuring that laws and regulations are only used for their intended purpose, and achieving energy affordability and security. Democrats prioritize building clean energy faster to slow climate change, addressing energy affordability, and protecting legacy environmental laws and community engagement.
As we discussed in the training, there are a number of key concepts that will require compromise from both sides of the aisle in order to reach a durable bipartisan permitting reform agreement. We’ll delve into the details of these in these upcoming trainings:
The Challenge of Energy Affordability and Security
First, with support from CCL’s Electrification Action Team, on February 5 I’ll examine what’s behind rising electricity rates and energy insecurity in the U.S. and how we can solve these problems. Electrification is a key climate solution in the transition to clean energy sources. But electricity rates are rising fast and face surging demand from artificial intelligence data centers. Permitting reform can play a key role in addressing these challenges.
Transmission Reform and Key Messages
Insufficient electrical transmission capacity is acting as a bottleneck slowing down the deployment of new clean energy sources in the U.S. Reforming cumbersome transmission permitting processes could unlock billions of tons of avoided climate pollution while improving America’s energy security and affordability. In this training on March 5, Jenn and I will dive into the details of the key clean energy and climate solution that is transmission reform, and the key messages to use when lobbying our members of Congress.
Clean energy projects often encounter long, complex permitting steps that slow construction and raise costs. Practical permitting reforms can help ensure that good projects move forward faster while upholding environmental and community protections. In this training on March 19, Jenn and I will examine permitting reforms to build energy infrastructure faster, some associated tensions and compromises that they may involve, and key messages for congressional offices.
Presidents from both political parties have taken steps to interfere with the permitting of certain types of energy infrastructure that they oppose. These executive actions create uncertainty that inhibits the development of new energy sources in the United States. For this reason, ensuring fair permitting certainty is a key aspect of permitting reform that enjoys bipartisan support. In this training on April 2, Jenn and I will discuss how Congress can ensure certainty in a permitting reform package, and key messages for congressional offices.
Community Engagement and Key Messages
It’s important for energy project developers to engage local communities in order to address any local concerns and adverse impacts that may arise from new infrastructure projects. But it’s also important to strike a careful balance such that community input can be heard and addressed in a timely manner without excessively slowing new clean energy project timelines. In this training on May 7, Jenn and I will examine how community engagement may be addressed in the permitting reform process, and key messages for congressional offices.
We look forward to nerding out with you in these upcoming advanced and important permitting reform trainings! 
Want to take action now? Use our online action tool to call Congress and encourage them to work together on comprehensive permitting reform.

DeBriefed 30 January 2026: Fire and ice; US formally exits Paris; Climate image faux pas
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Fire and ice
OZ HEAT: The ongoing heatwave in Australia reached record-high temperatures of almost 50C earlier this week, while authorities “urged caution as three forest fires burned out of control”, reported the Associated Press. Bloomberg said the Australian Open tennis tournament “rescheduled matches and activated extreme-heat protocols”. The Guardian reported that “the climate crisis has increased the frequency and severity of extreme weather events, including heatwaves and bushfires”.
WINTER STORM: Meanwhile, a severe winter storm swept across the south and east of the US and parts of Canada, causing “mass power outages and the cancellation of thousands of flights”, reported the Financial Times. More than 870,000 people across the country were without power and at least seven people died, according to BBC News.
COLD QUESTIONED: As the storm approached, climate-sceptic US president Donald Trump took to social media to ask facetiously: “Whatever happened to global warming???”, according to the Associated Press. There is currently significant debate among scientists about whether human-caused climate change is driving record cold extremes, as Carbon Brief has previously explained.
Around the world
- US EXIT: The US has formally left the Paris Agreement for the second time, one year after Trump announced the intention to exit, according to the Guardian. The New York Times reported that the US is “the only country in the world to abandon the international commitment to slow global warming”.
- WEAK PROPOSAL: Trump officials have delayed the repeal of the “endangerment finding” – a legal opinion that underpins federal climate rules in the US – due to “concerns the proposal is too weak to withstand a court challenge”, according to the Washington Post.
- DISCRIMINATION: A court in the Hague has ruled that the Dutch government “discriminated against people in one of its most vulnerable territories” by not helping them to adapt to climate change, reported the Guardian. The court ordered the Dutch government to set binding targets within 18 months to cut greenhouse gas emissions in line with the Paris Agreement, according to the Associated Press.
- WIND PACT: 10 European countries have agreed a “landmark pact” to “accelerate the rollout of offshore windfarms in the 2030s and build a power grid in the North Sea”, according to the Guardian.
- TRADE DEAL: India and the EU have agreed on the “mother of all trade deals”, which will save up to €4bn in import duty, reported the Hindustan Times. Reuters quoted EU officials saying that the landmark trade deal “will not trigger any changes” to the bloc’s carbon border adjustment mechanism.
- ‘TWO-TIER SYSTEM’: COP30 president André Corrêa do Lago believes that global cooperation should move to a “two-speed system, where new coalitions lead fast, practical action alongside the slower, consensus-based decision-making of the UN process”, according to a letter published on Tuesday, reported Climate Home News.
$2.3tn
The amount invested in “green tech” globally in 2025, marking a new record high, according to Bloomberg.

Captured

Sales of electric vehicles (EVs) overtook standard petrol cars in the EU for the first time in December 2025, according to new figures released by the European Automobile Manufacturers’ Association (ACEA) and covered by Carbon Brief. Registrations of “pure” battery EVs reached 217,898 – up 51% year-on-year from December 2024. Meanwhile, sales of standard petrol cars in the bloc fell 19% year-on-year, from 267,834 in December 2024 to 216,492 in December 2025, according to the analysis.
Spotlight
Looking at climate visuals
Carbon Brief’s Ayesha Tandon recently chaired a panel discussion at the launch of a new book focused on the impact of images used by the media to depict climate change.
When asked to describe an image that represents climate change, many people think of polar bears on melting ice or devastating droughts.
But do these common images – often repeated in the media – risk making climate change feel like a far-away problem from people in the global north? And could they perpetuate harmful stereotypes?
These are some of the questions addressed in a new book by Prof Saffron O’Neill, who researches the visual communication of climate change at the University of Exeter.
“The Visual Life of Climate Change” examines the impact of common images used to depict climate change – and how the use of different visuals might help to effect change.
At a launch event for her book in London, a panel of experts – moderated by Carbon Brief’s Ayesha Tandon – discussed some of the takeaways from the book and the “dos and don’ts” of climate imagery.
Power of an image
“This book is about what kind of work images are doing in the world, who has the power and whose voices are being marginalised,” O’Neill told the gathering of journalists and scientists assembled at the Frontline Club in central London for the launch event.
O’Neill opened by presenting a series of climate imagery case studies from her book. This included several examples of images that could be viewed as “disempowering”.
For example, to visualise climate change in small island nations, such as Tuvalu or Fiji, O’Neill said that photographers often “fly in” to capture images of “small children being vulnerable”. She lamented that this narrative “misses the stories about countries like Tuvalu that are really international leaders in climate policy”.
Similarly, images of power-plant smoke stacks, often used in online climate media articles, almost always omit the people that live alongside them, “breathing their pollution”, she said.

During the panel discussion that followed, panellist Dr James Painter – a research associate at the Reuters Institute for the Study of Journalism and senior teaching associate at the University of Oxford’s Environmental Change Institute – highlighted his work on heatwave imagery in the media.
Painter said that “the UK was egregious for its ‘fun in the sun’ imagery” during dangerous heatwaves.
He highlighted a series of images in the Daily Mail in July 2019 depicting people enjoying themselves on beaches or in fountains during an intense heatwave – even as the text of the piece spoke to the negative health impacts of the heatwave.
In contrast, he said his analysis of Indian media revealed “not one single image of ‘fun in the sun’”.
Meanwhile, climate journalist Katherine Dunn asked: “Are we still using and abusing the polar bear?”. O’Neill suggested that polar bear images “are distant in time and space to many people”, but can still be “super engaging” to others – for example, younger audiences.
Panellist Dr Rebecca Swift – senior vice president of creative at Getty images – identified AI-generated images as “the biggest threat that we, in this space, are all having to fight against now”. She expressed concern that we may need to “prove” that images are “actually real”.
However, she argued that AI will not “win” because, “in the end, authentic images, real stories and real people are what we react to”.
When asked if we expect too much from images, O’Neill argued “we can never pin down a social change to one image, but what we can say is that images both shape and reflect the societies that we live in”. She added:
“I don’t think we can ask photos to do the work that we need to do as a society, but they certainly both shape and show us where the future may lie.”

Factcheck: What it really costs to heat a home in the UK with a heat pump
Electric heat pumps are set to play a key role in the UK’s climate strategy, as well as cutting the nation’s reliance on imported fossil fuels.
Heat pumps took centre-stage in the UK government’s recent “warm homes plan”, which said that they could also help cut household energy bills by “hundreds of pounds” a year.
Similarly, innovation agency Nesta estimates that typical households could cut their annual energy bills nearly £300 a year, by switching from a gas boiler to a heat pump.
Yet there has been widespread media coverage in the Times, Sunday Times, Daily Express, Daily Telegraph and elsewhere of a report claiming that heat pumps are “more expensive” to run.
The report is from the Green Britain Foundation set up by Dale Vince, owner of energy firm Ecotricity, who campaigns against heat pumps and invests in “green gas” as an alternative.
One expert tells Carbon Brief that Vince’s report is based on “flimsy data”, while another says that it “combines a series of worst-case assumptions to present an unduly pessimistic picture”.
This factcheck explains how heat pumps can cut bills, what the latest data shows about potential savings and how this information was left out of the report from Vince’s foundation.
How heat pumps can cut bills
Heat pumps use electricity to move heat – most commonly from outside air – to the inside of a building, in a process that is similar to the way that a fridge keeps its contents cold.
This means that they are highly efficient, adding three or four units of heat to the house for each unit of electricity used. In contrast, a gas boiler will always supply less than one unit of heat from each unit of gas that it burns, because some of the energy is lost during combustion.
This means that heat pumps can keep buildings warm while using three, four or even five times less energy than a gas boiler. This cuts fossil-fuel imports, reducing demand for gas by at least two-fifths, even in the unlikely scenario that all of the electricity they need is gas-fired.
Since UK electricity supplies are now the cleanest they have ever been, heat pumps also cut the carbon emissions associated with staying warm by around 85%, relative to a gas boiler.
Heat pumps are, therefore, the “central” technology for cutting carbon emissions from buildings.
While heat pumps cost more to install than gas boilers, the UK government’s recent “warm homes plan” says that they can help cut energy bills by “hundreds of pounds” per year.
Similarly, Nesta published analysis showing that a typical home could cut its annual energy bill by £280, if it replaces a gas boiler with a heat pump, as shown in the figure below.
Nesta and the government plan say that significantly larger savings are possible if heat pumps are combined with other clean-energy technologies, such as solar and batteries.

Both the government and Nesta’s estimates of bill savings from switching to a heat pump rely on relatively conservative assumptions.
Specifically, the government assumes that a heat pump will deliver 2.8 units of heat for each unit of electricity, on average. This is known as the “seasonal coefficient of performance” (SCoP).
This figure is taken from the government-backed “electrification of heat” trial, which ran during 2020-2022 and showed that heat pumps are suitable for all building types in the UK.
(The Green Britain Foundation report and Vince’s quotes in related coverage repeat a number of heat pump myths, such as the idea that they do not perform well in older properties and require high levels of insulation.)
Nesta assumes a slightly higher SCoP of 3.0, says Madeleine Gabriel, the organisation’s director of sustainable future. (See below for more on what the latest data says about SCoP in recent installations.)
Both the government and Nesta assume that a home with a heat pump would disconnect from the gas grid, meaning that it would no longer need to pay the daily “standing charge” for gas. This currently amounts to a saving of around £130 per year.
Finally, they both consider the impact of a home with a heat pump using a “smart tariff”, where the price of electricity varies according to the time of day.
Such tariffs are now widely available from a variety of energy suppliers and many have been designed specifically for homes that have a heat pump.
Such tariffs significantly reduce the average price for a unit of electricity. Government survey data suggests that around half of heat-pump owners already use such tariffs.
This is important because on the standard rates under the price cap set by energy regulator Ofgem, each unit of electricity costs more than four times as much as a unit of gas.
The ratio between electricity and gas prices is a key determinant of the size and potential for running-cost savings with a heat pump. Countries with a lower electricity-to-gas price ratio consistently see much higher rates of heat-pump adoption.
(Decisions taken by the UK government in its 2025 budget mean that the electricity-to-gas ratio will fall from April, but current forecasts suggest it will remain above four-to-one.)
In contrast, Vince’s report assumes that gas boilers are 90% efficient, whereas data from real homes suggests 85% is more typical. It also assumes that homes with heat pumps remain on the gas grid, paying the standing charge, as well as using only a standard electricity tariff.
Prof Jan Rosenow, energy programme leader at the University of Oxford’s Environmental Change Institute, tells Carbon Brief that Vince’s report uses “worst-case assumptions”. He says:
“This report cherry-picks assumptions to reach a predetermined conclusion. Most notably, it assumes a gas boiler efficiency of 90%, which is significantly higher than real-world performance…Taken together, the analysis combines a series of worst-case assumptions to present an unduly pessimistic picture.”
Similarly, Gabriel tells Carbon Brief that Vince’s report is based on “flimsy data”. She explains:
“Dale Vince has drawn some very strong conclusions about heat pumps from quite flimsy data. Like Dale, we’d also like to see electricity prices come down relative to gas, but we estimate that, from April, even a moderately efficient heat pump on a standard tariff will be cheaper to run than a gas boiler. Paired with a time-of-use tariff, a heat pump could save £280 versus a boiler and adding solar panels and a battery could triple those savings.”
What the latest data shows about bill savings
The efficiency of heat-pump installations is another key factor in the potential bill savings they can deliver and, here, both the government and Vince’s report take a conservative approach.
They rely on the “electrification of heat” trial data to use an efficiency (SCoP) of 2.8 for heat pumps. However, Rosenow says that recent evidence shows that “substantially higher efficiencies are routinely available”, as shown in the figure below.
Detailed, real-time data on hundreds of heat pump systems around the UK is available via the website Heat Pump Monitor, where the average efficiency – a SCoP of 3.9 – is much higher.

Homes with such efficient heat-pump installations would see even larger bill savings than suggested by the government and Nesta estimates.
Academic research suggests that there are simple and easy-to-implement reasons why these systems achieve much higher efficiency levels than in the electrification of heat trial.
Specifically, it shows that many of the systems in the trial have poor software settings, which means they do not operate as efficiently as their heat pump hardware is capable of doing.
The research suggests that heat pump installations in the UK have been getting more and more efficient over time, as engineers become increasingly familiar with the technology.
It indicates that recently installed heat pumps are 64% more efficient than those in early trials.
Notably, the Green Britain Foundation report only refers to the trial data from the electrification of heat study carried out in 2020-22 and the even earlier “renewable heat premium package” (RHPP). This makes a huge difference to the estimated running costs of a heat pump.
Carbon Brief analysis suggests that a typical household could cut its annual energy bills by nearly £200 with a heat pump – even on a standard electricity tariff – if the system has a SCoP of 3.9.
The savings would be even larger on a smart heat-pump tariff.
In contrast, based on the oldest efficiency figures mentioned in the Green Britain Foundation report, a heat pump could increase annual household bills by as much as £200 on a standard tariff.
To support its conclusions, the report also includes the results of a survey of 1,001 heat pump owners, which, among other things, is at odds with government survey data. The report says “66% of respondents report that their homes are more expensive to heat than the previous system”.
There are several reasons to treat these findings with caution. The survey was carried out in July 2025 and some 45% of the heat pumps involved were installed between 2021-23.
This is a period during which energy prices surged as a result of Russia’s invasion of Ukraine and the resulting global energy crisis. Energy bills remain elevated as a result of high gas prices.
The wording of the survey question asks if homes are “more or less expensive to heat than with your previous system” – but makes no mention of these price rises.
The question does not ask homeowners if their bills are higher today, with a heat pump, than they would have been with the household’s previous heating system.
If respondents interpreted the question as asking whether their bills have gone up or down since their heat pump was installed, then their answers will be confounded by the rise in prices overall.
There are a number of other seemingly contradictory aspects of the survey that raise questions about its findings and the strong conclusions in the media coverage of the report.
For example, while only 15% of respondents say it is cheaper to heat their home with a heat pump, 49% say that one of the top three advantages of the system is saving money on energy bills.
In addition, 57% of respondents say they still have a boiler, even though 67% say they received government subsidies for their heat-pump installation. It is a requirement of the government’s boiler upgrade scheme (BUS) grants that homeowners completely remove their boiler.
The government’s own survey of BUS recipients finds that only 13% of respondents say their bills have gone up, whereas 37% say their bills have gone down, another 13% say they have stayed the same and 8% thought that it was too early to say.
