Only around a third of the latest country climate pledges submitted to the UN express support for the “transition away from fossil fuels”, according to Carbon Brief analysis.
Several countries even have used their 2035 climate plans to commit to increasing the production or use of fossil fuels, predominately gas, the analysis finds.
The first global stocktake of progress to tackle climate change, agreed at the COP28 climate summit in Dubai in 2023, calls on all countries to contribute to “transitioning away from fossil fuels”.
Countries were meant to explain how they are implementing the outcomes of the global stocktake, including their contribution to transitioning away from fossil fuels, in their latest climate plans.
However, just 23 of the 63 plans submitted to the UN so far express support for “transitioning away from fossil fuels”, or the “phase out” or “phase down” of their use.
In addition, six countries, including Russia, Nigeria and Morocco, use their climate plans to commit to boosting gas production.
Some two-thirds of countries have not yet announced or submitted their pledges, missing not only the UN deadline of 10 February, but also an extension to September.
How to address the lack of sufficient action from countries with their latest plans is billed to be one of the major issues up for debate at the COP30 climate summit in Brazil next month.
Taking stock
In 2015, countries forged the Paris Agreement, the landmark deal to keep temperature rise “well-below” 2C, with “aspirations” to limit global warming to 1.5C of warming by the end of this century.
At the time, countries’ initial pledges were not enough to put the world on track to meet the temperature targets, so they built a “ratchet mechanism” into the Paris Agreement, requiring them to keep increasing their ambition in the following years.
As part of this, countries agreed to submit new, more ambitious plans every five years detailing what they are doing to take action on climate change and adapt to its impacts. These are called “nationally determined contributions” (NDCs).
The Paris Agreement also stated that, following on from these plans, “global stocktakes” should be conducted to assess collective progress in meeting the temperature goal.
The first global stocktake concluded at the COP28 climate summit in Dubai in 2023, with countries agreeing to a new document setting out how they will respond to a lack of sufficient action to meet the Paris goals.
The two-week talks saw fierce debate about how fossil fuels – the main driver of human-caused climate change – should be referred to in this text.
In the end, the stocktake “calls on” all countries to “contribute to” a list of global goals, including “transitioning away from fossil fuels…accelerating action in this critical decade” towards net-zero by 2050.
It was the first time that countries formally acknowledged the need to transition away from fossil fuels in almost 30 years of international climate negotiations.
However, many countries were disappointed that the text did not contain a firmer commitment to phase out all fossil fuels, or even just those with “unabated” emissions.
After Dubai, countries were expected to come up with new NDCs for 2035 that explained how they responded to the priorities set out in the stocktake.
The deadline for submitting the “3.0” NDCs was 10 February 2025, which 95% of countries missed.
On 24 September, the UN convened a climate summit in New York at the sidelines of the UN general assembly in the hope of encouraging more countries to come forward with new NDCs.
China stole the show at the event, announcing a pledge – although not yet formally submitted to the UN – to cut greenhouse gas emissions to 7-10% below peak levels by 2035. Several other countries announced new plans, including Russia, Turkey and Bangladesh.
Following the summit, around one-third of countries have announced or submitted their 2035 NDCs.
Fossil-fuel focus
For the analysis, Carbon Brief reviewed each of the NDCs submitted to the UN to determine whether they express support for “transitioning away” from fossil fuels or for phasing them out or “down”.
Countries were considered to have expressed support if they explicitly mentioned the terms “transition” or “phase out/down” in relation to “fossil fuels” when speaking about their own actions to address climate change.
Some countries spoke in general terms about “reducing” or “replacing” fossil fuels, but did not explicitly reference the need to transition away from or phase them down or out. Others spoke about transitioning to a clean or renewable-based economy, but did not explicitly mention fossil fuels.
For the purposes of this analysis, all of these countries were considered to have not expressed support for the need to transition away from fossil fuels.
In addition, some countries mentioned in their NDCs that the global stocktake calls for a transition away from fossil fuels, but did not say that transitioning away from fossil fuels would be part of their own actions to address climate change.
These countries were also considered to have not expressed support for the need to transition away from fossil fuels.
Overall, the results show that only one-third of countries express support for the need to transition away from fossil fuels in their NDCs.
Countries used varying language when speaking about the need to transition away from fossil fuels.
Some directly acknowledged that transitioning away from fossil fuels was a key conclusion of the global stocktake and committed to doing this within their own borders.
This includes the UK, Brazil, Canada, Australia, Singapore, Lebanon and Niue. For example, the UK’s NDC states:
“At home and in line with the outcomes of the GST [global stocktake], the UK is committed to transitioning away from fossil fuels to achieve net-zero by 2050.”
Other countries chose to commit to “phasing out” fossil fuels instead of “transitioning away”.
This includes Iceland and Vanuatu. Similarly, Colombia’s NDC says:
“NDC 3.0 reaffirms that the phasing out of fossil fuels is not only a climate imperative, but also an opportunity to strengthen energy sovereignty [and] democratise the benefits of the transition.”
(Colombia and Vanuatu were two of the countries that were disappointed not to see a commitment to phase out fossil fuels included within the global stocktake text.)
Barbados, an island nation known for its strong commitment to climate action, committed in its NDC to “achieve a fossil fuel-free economy” by 2040. In addition, Chile pledged to contribute to the “elimination of fossil fuels”.
In the analysis, these pledges were considered to be support for transitioning away from fossil fuels, despite not using the terms “transition” or “phase out”.
The table below shows the language used by each of the 21 countries that expressed support for transitioning away from fossil fuels, according to the analysis.
| Country | Expression of support for ‘transitioning away from fossil fuels’ in NDC |
|---|---|
| United Kingdom | “At home and in line with the outcomes of the GST, the UK is committed to transitioning away from fossil fuels to achieve net-zero by 2050.” |
| Brazil | “Brazil will respond to the call to contribute to global efforts under paragraph 28 of decision 1/CMA.5, through the policies and national efforts below, including those under the National Climate Plan. In addition, Brazil would welcome the launching of international work for the definition of schedules for transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner, with developed countries taking the lead, on the basis of the best available science, reflecting equity and the principle of common but differentiated responsibilities and respective capabilities in the light of different national circumstances and in the context of sustainable development and efforts to eradicate poverty, as per paragraph 6 of decision 1/ CMA.5.” |
| Canada | “Canada also remains committed to implementing the mitigation outcomes of the Global Stocktake (GST), agreed at COP28…This includes…transitioning away from fossil fuels in energy systems.” |
| Lebanon | “Guided by the UAE Consensus reached at COP28, which calls on all Parties to transition away from fossil fuels and strengthen support for adaptation, this NDC reflects Lebanon’s commitment to scaling ambition while addressing national vulnerabilities.” |
| Iceland | “Iceland’s NDC takes note of the outcome of the global stocktake, according to Decision 1/CMA.5. Specifically, Iceland’s NDC seeks to represent the need for deep, rapid and sustained reductions in greenhouse gas emissions in line with 1.5°C pathways by contributing to the phase-out of fossil fuels across sectors and the strategic, fair and ambitious implementation of carbon capture, utilisation and storage, according to para. 28.” |
| Barbados | “In 2020, the Government of Barbados set the aspirational goal to achieve a fossil fuel-free economy and to reduce GHG emissions across all sectors to as close to zero as possible by 2030. In light of the significant challenges faced by the country, the aspirational goal is currently expected to be reached around 2040.” |
| Chile | “In 2023, within the framework of the 28th Conference of the Parties to the UNFCCC (COP) in Dubai, the report on the First Global Stocktake, designed within the framework of the Paris Agreement to assess the global response to the climate crisis, was presented…Among its main conclusions, the agreement to move towards the elimination of fossil fuels in energy systems…stands out. All these conclusions are addressed in this NDC, demonstrating Chile’s commitment to climate ambition.” |
| Vanuatu | “Moving beyond our current net-zero status, this NDC recommits Vanuatu to rapidly phasing out fossil fuels, deeply decarbonising and transitioning completely to a circular economy.” |
| Pakistan | “Natural gas and furnace oil are set to decline, with net reductions of 2,147 MW and 430 MW respectively, as per IGCEP 2025-2035, signaling a gradual phase down of fossil fuels in Pakistan’s capacity mix.” |
| Colombia | “NDC 3.0 reaffirms that the phasing out of fossil fuels is not only a climate imperative, but also an opportunity to strengthen energy sovereignty, democratize the benefits of the transition, and consolidate Colombia as a Power of Life.” |
| Niue | Niue understands the need to transition from fossil fuel-based electricity generation to renewable energy to reduce the GHG emissions footprint and ensure energy security.” |
| Singapore | “Singapore is contributing to the first global stocktake’s call to triple global renewable energy capacity and double the global average annual rate of energy efficiency improvements by 2030. We are also supporting efforts to transition away from fossil fuels in energy systems and phase out inefficient fossil fuel subsidies.” |
| Australia | “The global stocktake recognised the global direction of travel in its consensus call to transition away from fossil fuels in energy systems and to phase-down unabated coal-fired power. In Australia, our transition is underway.” |
| United Arab Emirates | “The GST Outcome at COP28, together with the broader UAE Consensus and the work under the Troika, has provided a strong impetus for the UAE NDC 3.0. The outcome of the first GST notably emphasizes the need to transition away from fossil fuels in energy systems in a just, orderly and equitable manner, urging parties to adopt ambitious, economy-wide emission reduction targets.” |
| Japan | “The items listed in decision 1/CMA.5 have been incorporated to the greatest extent possible into the Plan for Global Warming Countermeasures, which is a comprehensive implementation plan for achieving Japan’s NDC.” |
| Bolivia | “The persistent dependence on fossil fuels, both for electricity generation and transportation, not only contributes to national greenhouse gas emissions, but also exposes the country to volatility in international oil and gas prices, highlighting the urgency of a fair, sovereign, and resilient energy transition toward renewable sources.” |
| Nicaragua | “The transition to an energy matrix less dependent on fossil fuels is a fundamental priority of the government.” |
| Marshall Islands | “This NDC also demonstrates our drive, our achievements, and the challenges we face. In particular, we detail our domestic actions to contribute to the collective commitments made following the global stocktake, including the tripling of renewable energy, doubling of energy efficiency and removal of fossil fuel subsidies, all in pursuit of accelerating the transition away from fossil fuels this decade.” |
| Cambodia | “This transition will be implemented in two key phases: 70% renewable energy by 2030, followed by a further increase to 72% by 2035, ensuring a gradual yet decisive shift away from fossil fuel dependency in the power sector.” |
| Bangladesh | “Transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner [is] central to Bangladesh’s contribution to the global response to climate change. The NDC 3.0 commitments are designed not only to reduce Greenhouse Gas (GHG) emissions but also to accelerate the just energy transition, promote zero- and low-emission technologies, and enhance climate resilience.” |
| Tuvalu | “We are steadfast in our transition to 100% renewable energy.” |
| Sri Lanka | “With abundant solar, wind, and hydropower resources, Sri Lanka has a clear opportunity and expressed ambitious commitments to move towards total electricity generation based on renewable sources, to transition away from fossil fuels toward cleaner, decentralised energy systems.” |
| Nepal | Nepal’s NDC is “informed” by Decision 1/CMA.5 Outcome of the first GST, “such as 1.5C decarbonisation pathway…just transition away from fossil fuels in energy systems.” |

Separately, the thinktank E3G has examined how countries speak about their policies for reducing fossil fuels in their NDCs.
It found that more than two-thirds of countries include “explicit references to displacing fossil fuels in their electricity mix”.
However, E3G also noted that “specific language on winding down the production of coal, oil, and fossil gas is lacking in almost all NDCs”.
‘Transitional fuel’
Carbon Brief also examined each of the submitted NDCs to see how countries speak about new fossil-fuel production and use within their borders.
Six of the 64 nations – around 10% – used their NDCs to pledge to increase fossil-fuel production or use, predominately gas, claiming this could contribute to their efforts to lower emissions.
In its NDC, the world’s fourth biggest emitter, Russia, says it “emphasises the importance of implementing a just transition to low-emission development models using all available solutions”, including “gas as a transition fuel and technologies for reducing emissions in coal-fired power generation”.
During negotiations on the stocktake text in 2023, Russia had pushed successfully to include a controversial paragraph that says “transitional fuels can play a role in facilitating the energy transition while ensuring energy security”, Climate Home News reported.
The publication noted that, after this text was agreed, Antigua and Barbuda negotiator Diann Black-Layne called it a “dangerous loophole”, adding that gas is also a fossil fuel that “we need to transition away from”.
Several African nations, including Nigeria, Morocco, Mauritius and Zimbabwe, also pledged to boost the production or use of gas as part of their “climate” actions.
Nigeria, Africa’s second biggest emitter, says that the country “relies heavily on the oil and gas industry” and that the sector will be “called upon to further grow while adopting sustainability measures”. It continues:
“Natural gas use will be boosted, serving as a key transition fuel in Nigeria’s move towards increased adoption of renewable energy for meeting its net-zero emissions target.”
The world’s energy watchdog, the International Energy Agency, recently reemphasised that there would be no need for any new fossil-fuel production, if the world cuts emissions in line with limiting global warming to 1.5C.
It comes after the world’s top court this year concluded that new fossil-fuel production, consumption, the granting of exploration licences or the provision of subsidies “may constitute an internationally wrongful act”, leaving the states involved vulnerable to legal action.
COP30 calls
After nearly all nations missed the deadline for submitting NDCs in February, UN climate chief Simon Stiell asked laggard countries to do so by the end of September.
This will allow their plans to be included in a new report synthesising the level of progress contained within the latest NDCs, which is due to be published on 24 October. (Less than a third of nations met Stiell’s request.)
The report will come just before COP30, which will take place from 10-21 November in the rainforest Brazilian city of Belém.
Whether and how to respond to the insufficient progress contained within these NDCs, including whether to call for increased ambition in line with the outcomes of the first global stocktake, are among the key issues up for debate at the summit.
The Brazilian presidency is pushing for a formal COP decision on any “disappoint[ment]” over NDCs falling short, collectively, of what is needed to avoid dangerous global warming.
However, other countries would need to agree to this proposal at the summit.

‘Energy Vampires’: Greenpeace calls for moratorium on data centres as new report reveals frenzied rollout would derail energy transition
SYDNEY, Wednesday 27 May 2026 — A new report from Greenpeace Australia Pacific and independent expert Ketan Joshi reveals how the frenzied rollout of AI data centres in Australia is set to derail the renewable energy transition, entrench gas and turbocharge climate pollution, prompting calls for an urgent moratorium on data centre approvals until appropriate guardrails are in place.
The report, Energy Vampires: the AI data centres draining Australia, reveals the staggering scale of data centre growth in Australia, set to follow a US path of emissions blowout and rising community opposition to the resource-hungry facilities. The report exposes the links between the data centre lobby and the gas industry, who are using data centre growth to justify extracting more gas.
Greenpeace Australia Pacific is calling on the Federal Government to urgently implement a moratorium on the construction and approval of new data centres, until appropriate regulations and safeguards have been put in place to protect the climate and communities.
Key findings:
- Data centres are already failing to cover their own demand with additional renewable energy, and resisting calls to mandate that they do.
- At its peak, Australia’s biggest proposed data centre, the 1GW Mamre Road Data Centre Campus in Western Sydney, will generate annual emissions equivalent to 560,000 petrol cars, or all domestic flights within NSW in 2023.
- There are early signs of a data centre-fuelled gas boom in Australia, including proposals for new on-site gas, as seen in the US.
- Cloud Carrier’s proposed gas-fired data centre in NSW would wipe out the state’s entire projected 2028 emissions cuts.
- Even if only 1 in 4 new Australian data centres were powered by new on-site gas, it would result in 2.8x higher total emissions compared to using grid power.
Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “Australia is completely unprepared for the magnitude of impacts of the AI-driven data centre frenzy. Data centres are being rolled out at a feverish pace, with some of the largest planned for Australia consuming as much energy as Adelaide. The recent federal and state energy minister communique is a positive first step towards regulating the data centre industry, and managing its impact on the energy transition and the communities where they’re being built.
“But we should all be concerned by the extreme lack of scrutiny being applied to the companies leading the data centre charge in Australia and their proposals. Without strong, legislated standards, we risk replicating the disastrous US pattern, where Big Tech corporations have carte blanche to drain energy and water, and build new, polluting gas and diesel-powered plants to fuel their operations. This has seen mounting community opposition that transcends party politics, something we’re beginning to see here in Australia.
“Greenpeace is calling for a moratorium on new data centre approvals and construction until we have clearly defined, enforceable regulations and standards in place to govern this industry — essential if we hope to avoid the alarming outcomes outlined in this report.
“Australia is not a playground for Big Tech corporations. It is time our leaders stepped up and took seriously their role as custodians of our resources and protectors of our society and environment.”
Ketan Joshi, independent report author and climate expert said: “Impatience is not a virtue. The reckless data centre buildout is heaping massive new load onto the grid, meaning renewables have to run harder just to stay in the same spot. Currently data centres increase coal and gas output and delay shutdowns, while plugging polluting gas into data centres does the damage directly instead.
“Unless the data centre industry builds no new fossil fuels and far more new renewables than new demand, we end up worse off. Australia’s gas industry sees a lifeline in an unchecked data centre frenzy, and the feeling seems to be mutual.
“Data centre demand projections keep jabbing upwards each revision, and emissions projections keep getting worse. Everywhere in the world facing this frenzy sees the same trend.
“Data centre moratoria have bipartisan support in countries around the world as the only path to reintroducing careful, considered governance of data centre growth. In the context of an irrational, unjustified panic, a temporary pause brings reason and rationality, along with bringing power to communities.”

A new report from Greenpeace Australia Pacific and independent expert Ketan Joshi reveals how the frenzied rollout of AI data centres in Australia is set to derail the renewable energy transition, entrench gas and turbocharge climate pollution, prompting calls for an urgent moratorium on data centre approvals until appropriate guardrails are in place.
The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes.
Key findings
- The frenzied rollout of AI data centres in Australia is rushing through massive new projects, which will derail Australia’s energy transition unless the government urgently intervenes. Our conservative assumptions mean this impact is understated, in this analysis.
- Australia’s biggest proposed data centre, the 1GW Mamre Road Data Centre Campus in Western Sydney, will generate peak annual grid emissions equivalent to that produced by 560,000 petrol cars for a year or all domestic flights within NSW in 2023.
- Data centres already fail to cover their own emissions with new renewables and their rollout will dramatically hold back Australia’s energy transition.
- No data centre operator analysed in this report adequately proves their claim of driving Australia’s renewable energy growth. Claims they are doing this through truly “additional” new power purchasing agreements for renewable energy are unsubstantiated.
- There are early signs of a data centre-fuelled gas boom in Australia, which will come with massive, nationally significant climate costs. For example, the Tamboran proposal for the Northern Territory would effectively double the state’s emissions. In NSW, Cloud Carrier’s proposed gas-fired project would wipe out NSW’s entire projected 2028 emissions cuts.
- Even if only 1 in 4 new Australian data centres were powered by new on-site gas, it would result in 2.8x higher total emissions compared to using grid power.
- New analysis shows that on-site gas for data centres globally could fuel emissions that exceed Brazil’s total power grid emissions by 2030.
- Fossil fuel corporations are quietly joining the data centre lobby group as members, and sponsoring and attending technology industry conferences. The two industries are reinforcing each other’s talking points and PR spin.
- Data centre operators do not disclose the customers of an individual facility, the purpose of the computations performed there, or site-specific energy consumption, despite the industry’s defense of its ‘critical infrastructure’ status or claims of transparency. It is a matter of public record that AI is being used for abuse, war and other human rights violations.
- Data centres can be ‘right sized’ through community ownership schemes, well-deployed AI software and strict moratoria to allow for democratic governance of this industry.
This report recommends:
- An urgent moratorium on data centre development until safeguards are legislated
- Binding, legislated standards for AI development, including substantiated claims of additional renewable energy
- Full disclosure of services delivered, emissions, finances and energy use, per project
- Full assessment of compliance with human rights frameworks
