The right-wing populist Hungarian government led by Viktor Orbán has suffered a landslide electoral defeat to the centre-right Tisza party, led by Péter Magyar.
This brings to an end 16 years of rule by Orbán and his Fidesz party, a move welcomed by many around the world who were concerned about Hungary’s “slide toward authoritarianism”.
Hungary has played a disproportionate role in EU climate and energy policy in recent years, by repeatedly vetoing climate action and by delaying the phaseout of Russian fossil-fuel imports.
Magyar did not prioritise climate and energy issues in his electoral campaign, but he has championed cooperation with the EU and proposed a 2035 deadline for “eliminating Russian energy dependence”.
Hungarian experts tell Carbon Brief that, while the new government is yet to be formed, it is likely that Magyar will move quickly to secure EU funds for “green” measures.
One expert notes that “this is not a progressive pivot”, with Hungary unlikely to emerge as a climate leader in the EU, even if it is less disruptive to the bloc’s wider climate strategy.

What was Orbán’s approach to climate action?
Hungary has had a mixed record on climate change under then prime minister Orbán, supporting some relevant actions while opposing others – particularly those taken at an EU level. This broadly reflects his Fidesz party’s populist and Eurosceptic leanings.
Orbán has described the EU’s climate goals as a “utopian fantasy” that would “destroy the middle class”. He has also accused “western elites” of wanting people to “live in fear” of climate change.
Yet, despite being embraced by climate sceptics elsewhere and supporting climate-sceptic lobbyists, Orbán’s government has not overtly adopted such sceptical rhetoric.
In fact, reflecting broad Hungarian support for climate action, Orbán has framed his nation as a “climate champion” – albeit one taking a “pragmatic” approach. This was captured in his speech at the COP29 summit in 2024, when he said:
“We must continue advancing the green transition, while also maintaining our use of natural gas, oil and nuclear energy…Our climate policy should be guided by careful consideration and common sense, not by ideology, alarmism or panic.”
Domestically, Orbán’s government has pursued various climate goals, including a 2050 net-zero target, phasing out coal power by 2029 and supporting the expansion of solar power.
What will be the new Hungarian government’s climate and energy policies?
Climate change was not a major issue in the April election and Magyar, the incoming prime minister, hardly mentioned it in his campaign.
However, the 243-page manifesto released by his Tisza party includes many climate-related proposals, such as home insulation, railway electrification and tackling drought.
The document says some of these measures – notably “energy modernisation and efficiency programmes” – will be funded with billions of euros in EU funds that have been frozen under Orbán. (See: How will the new government approach EU climate policy?)
One notable pledge is to “double the share of renewable energy in domestic energy supply” by 2040. As the chart below shows, Hungary already generates three-quarters of its electricity from clean sources – predominantly Paks, its single nuclear power plant.
Nearly a third of Hungary’s electricity comes from solar, which has benefited from supportive government schemes in recent years. In contrast, for years, the Orbán government blocked the construction of wind turbines, meaning there is virtually no wind power in Hungary.
The Tisza manifesto recognises this imbalance, stating that “we will abolish the unnecessary restrictions preventing the installation of new wind turbines”, while also supporting geothermal energy.
Energy prices are a key political issue in Hungary, as they are in many nations around the world. Orbán’s “utility cost reduction” has been a flagship policy for many years, capping household prices using large state subsidies.
During the election, Orbán accused his opponent of planning to get rid of the energy price cap. In fact, the Tizsa manifesto says the new government will “maintain and expand” the scheme and add new VAT cuts on firewood.
Despite having few batteries and electric vehicles (EVs) domestically, Hungary has emerged in recent years as a major battery manufacturer, driven by Chinese and South Korean investment. However, this boom has sparked environmental and social concerns.
Zsolt Lengyel, founder and chair of the Institute for European Energy and Climate Policy (IEECP), tells Carbon Brief:
“Orbán’s battery and EV strategy – in theory, a flagship of the transition – has backfired politically…So Tisza inherits a paradox: it needs to accelerate the transition, but does so in an environment where parts of that transition have already lost public legitimacy.”
With much still unknown about Magyar’s attitude to climate and energy policy, some Hungarian experts that Carbon Brief spoke to cautioned against “speculation” and “wishful thinking” when assessing his climate credentials.
How will the new government approach EU climate policy?
There is cautious optimism among EU officials and leaders that a Hungarian government led by Magyar will be more cooperative on EU-led initiatives.
Under Orbán, Hungary has been a vocal and persistent opponent of EU climate policies.
Since 2011, 21 of all the 48 vetoes on joint EU actions have been used by Hungary. These include blocking efforts to sanction Russia following the country’s invasion of Ukraine. (See: What has the new leadership said about Russian fossil fuels?)
Among other issues, Hungary has vetoed or obstructed progress on the EU’s 2050 net-zero target, the “fit for 55” legislative package to help meet that goal and the 2035 ban on petrol and diesel cars.
Generally, this opposition did not totally block these policies, as most did not require unanimous agreement among EU member states. However, it did tend to slow down or complicate the process. Hungary was also not acting alone – it was often joined by fellow eastern and central European states, claiming the policies would have high costs.
Nevertheless, the Orbán government’s aversion to the EU has taken it further than other states. In recent months, for example, Hungary has launched a legal case against the EU over its phaseout plan for Russian oil and gas imports.
In this context, Lengyel tells Carbon Brief:
“Orbán’s exit removes Hungary’s most damaging feature in EU climate politics: the ideological reflex to oppose ‘anything Brussels does’.”
However, just because Magyar is less hostile to the EU does not mean his government will be a climate leader.
Magyar’s centre-right Tisza party is aligned with the European People’s Party (EPP) grouping in the European parliament, which has been instrumental in weakening EU climate goals in recent months. Given this, Lengyel tells Carbon Brief.
“Let’s be clear: this is not a progressive pivot. Tisza sits close to the EPP mainstream and is unlikely to challenge it. If anything, it will follow it, including on any watering down of green-deal elements.”
Crucially, Hungary is entitled to billions of euros of EU funds that have been blocked due to breaches of conditions regarding the rule of law and human rights under Orbán.
These include €9.5bn for Hungary’s recovery and resilience plan, the EU’s post-Covid recovery fund, much of which is earmarked for the “green transition”.
This finance needs to be disbursed before the end of August – and both Magyar and the EU have been clear that unlocking the funds is a priority.
Jozsef Feiler, director of the south-east Europe and Hungary programme at the European Climate Foundation, which funds Carbon Brief, says “full EU compliance” will be crucial for Hungary over the coming months, in order to obtain these funds. He tells Carbon Brief:
“The economic and financial stability of the new government [will depend] on obtaining the recovery and resilience facility funds and managing some kind of absorption before the 26 August hard deadline.”
Another early challenge will be the new government’s approach to the new part of the EU’s emissions trading scheme (ETS) – known as ETS2 – which will put a price on emissions from buildings, cars and other sources not covered in the original ETS.
ETS2 is already facing criticism from member states concerned about rising fuel costs. Moreover, Hungary is likely to be one of the countries that is most exposed to high fossil-fuel prices.
István Bart, a senior director in carbon pricing at the Environmental Defence Fund, tells Carbon Brief that Orbán’s government has done little to help with the implementation of ETS2, which is currently due to start in 2028. He notes that, with the question of affordability so fraught in Hungary, it is unclear how Magyar will tackle this issue.
What has the new leadership said about Russian fossil fuels?
One of the most notable policy statements made in Tisza’s manifesto is a commitment that:
“By 2035, we will eliminate Russian energy dependence and diversify our domestic energy supply.”
Despite its relatively clean electricity supply, Hungary is still heavily reliant on fossil fuels – including in its transport, heating and industrial sectors – the majority of which are imported.
Russia is Hungary’s main fossil-fuel trading partner, with the Druzhba and TurkStream pipelines supplying much of the smaller nation’s needs for oil and gas, respectively.
Among EU member states, Hungary is second only to Slovakia in terms of reliance on Russian fossil fuels. In 2024, 74% of Hungary’s gas and 48% of its oil were imported from Russia, as shown in the chart below.

Since Russia’s full-scale invasion of Ukraine in 2022, most EU nations have taken steps to reduce their dependence on Russian fossil fuels.
The EU has implemented a series of sanctions on Russia and the European Commission launched the REPowerEU plan to “fully end dependency on Russian energy”.
Under Orbán, however, Hungary has obstructed efforts to wean the EU off Russian fossil fuels, citing energy-security concerns. It has successfully negotiated exemptions from Russian oil sanctions, allowing the country to increase its reliance on cheap Russian crude.
The REPowerEU regulation involves a ban on Russian pipeline gas by September 2027. Unlike sanctions, the EU did not need unanimity among states to pass this.
It is notable that Tisza has only committed to end reliance on Russian energy by 2035 – eight years after the EU deadline. It is unclear how Magyar’s new government will negotiate this discrepancy, especially given long-term contracts with Russian suppliers.
Hungary also relies on Russia for nuclear technology and supplies of uranium for its nuclear plant. In its manifesto, Tisza says it will explore the possibility of sourcing nuclear fuel from US or French suppliers, as well as building small modular reactors.
Orbán had already started pursuing diversified nuclear and fossil-fuel supplies by buying from the US, even as it secured exemptions from US sanctions on Russian energy imports. It is possible that Tisza may maintain this approach.
However, with the Iran war and energy crisis looming in recent months, Bart, from EDF, tells Carbon Brief:
“Before the Iran war started, you could have said: ‘Why don’t you just buy LNG [liquified natural gas]?’…Now it seems like less of an option, so, unfortunately, in the short term, [Russian gas] has to stay because we don’t really have an alternative.”

Every country needs a model to help optimise its energy transition
Claver Gatete is Executive Secretary of the UN Economic Commission for Africa. Jason Veysey is Energy Modeling Program Director and Senior Scientist at the Stockholm Environment Institute. Lisa Sachs is Director of the Columbia Center on Sustainable Investment at Columbia University.
The case for global energy transition has rarely been clearer. The closure of the Strait of Hormuz earlier this year exposed the cost of unplanned, fossil-dependent systems, while the falling cost of renewables, the rising penetration of electric vehicles, and the growing value of demand flexibility have made the direction of travel obvious. The benefits of a clean, secure, integrated system are no longer in dispute. What remains unclear is how to build it.
Countries around the world have called for faster renewable energy deployment and alternative energy arrangements. A secure, affordable, resilient, decarbonised system requires specific investments in specific places in a specific sequence, optimised across sectors and borders. But very few governments have the analytical foundation to translate those imperatives into investment.
The two instruments that are supposed to determine investment priorities for decarbonisation – Nationally Determined Contributions (NDCs) and country platforms – cannot answer the most basic question facing any country undertaking an energy transition: what should the energy system look like?
To close this gap, every country needs a bankable, economy-wide optimisation model for its energy system. A model is not a plan, but it can help answer the critical question of what the future energy system should look like. It shows how optimal scenarios vary as assumptions and policies are adjusted, calculates investment requirements and sequencing, and quantifies how system costs are affected by assumptions, policies, and exogenous variables like trade policy and financing terms.
Tool for efficient investment
Optimisation is a simplified way of simulating an energy system, but it can be an extremely powerful tool for moving energy planning from reactive (how do we manage the disparate actions in the energy system?) to intentional (what energy system underpins our national objectives?). A model can show how optimal scenarios vary as assumptions and policies are adjusted, and how investment requirements are quantified and sequenced.
Optimisation models can treat the energy system and the sectors it serves as an integrated whole, optimising across sectors and projects in ways that can be mutually reinforcing. If considered independently, growth in industrial demand, transport electrification, and digital infrastructure can add stress to the energy system. But an optimised plan can arrange these and other changes in an efficient, synergistic way.
Two to tango: How governments can unlock private investment for national climate goals
New load can be added where low-cost power is available; industrial customers can ensure the viability of investments in energy supply; electric vehicle charging policy can smooth load curves and reduce costs for all consumers.
Additionally, optimisation modeling can also change the financeability of investments. Taken alone, each project faces uncertainty about the rest of the system, which raises the cost of capital and causes projects to stall or unwind after contracts are signed. A coherent, optimised plan makes visible the coordination that private capital would otherwise have to bet on: identified offtake, sequenced and committed transmission, contracted power supply, and so on.
What COP31 and COP32 should do
The upcoming COPs in Turkey and Ethiopia can shift the center of gravity of international climate cooperation from fragmented commitments to planning. Three moves are urgently needed.
First, optimised, economy-wide, long-term energy system planning must be the foundation on which any meaningful NDC, country platform, or finance commitment rests. NDCs are typically drafted by environment or single-line ministries, with limited cross-sectoral input from ministries of energy, finance, and planning. They contain targets, derived from sectoral strategies or national commitments, not from an analytically grounded picture of what the energy system should look like and what investments would make it work. Country platforms are generally a portfolio of investments assembled from existing project pipelines, rather than derived from a system-level analysis of what an optimised, decarbonised energy system would require.
Second, recognise regions as a key planning unit. Modern integrated energy systems are inherently regional. Renewable endowments are unevenly distributed; balancing variable supply across borders lowers aggregate cost, reduces redundant backup capacity, and unlocks economies of scale no individual nation can achieve. Many energy investments in Southeast Asia, East Africa, Southern Africa and Central Asia may only be financeable in a regional context. Assessing domestic infrastructure without regional optimisation perpetuates the perception that decarbonisation is more expensive than it is.
COP31 leaders unveil global targets, with spotlight on electrification
Third, finance the planning capacity. A coordinated commitment by multilateral development banks, bilateral donors, and philanthropic partners to help every region and its constituent countries develop and maintain their own modelling capability, with open-source tools and regional analytical hubs, would close the most consequential gap in the current architecture. The cost is small relative to current spending on country platforms, failed project preparation, and misallocated infrastructure investment.
This includes supporting regional institutions such as the ASEAN Centre for Energy, the African Energy Commission, regional power pools, and the Latin American and Caribbean Energy Organization to determine what optimised regional systems require. Country-by-country pledging, repeated at every COP, will not deliver what meaningfully integrated systems can.
The 2026 energy crisis made the cost of unplanned, fossil-dependent systems newly visible. That window of clarity will close. The international community should seize the moment to build the planning foundation that has been missing for thirty years, rather than commissioning another round of NDCs or pledges, striving for outcomes neither was designed to deliver.

Explainer: How the ‘super El Niño’ will reshape the world’s weather
The world is currently experiencing what is expected to become the strongest El Niño on record – dubbed a “super El Niño” by many.
El Niño is the warm phase of a recurring climate pattern in the tropical Pacific that releases heat from the ocean into the atmosphere.
This temporarily raises global temperatures and reshapes rainfall and extreme weather around the world – impacting the lives of billions of people.
The current El Niño event began in June and is expected to last into 2027.
El Niño is part of a wider climate pattern called the El Niño-Southern Oscillation (ENSO) cycle.
The ENSO cycle also has a cool phase, known as La Niña, as well as a “neutral” phase. El Niño and La Niña events typically last between nine and 12 months, but can go on longer.
Below, Carbon Brief explains how the ENSO cycle works, its impacts on extreme weather and global temperatures and why this El Niño event is projected to be the most intense since records began.

Analysis: The two largest reservoirs in the US have hit record-low levels
The second-largest reservoir in the US reached a record-low water height on Saturday – just days after the country’s largest reservoir broke its own record.
Both Lake Mead and Lake Powell are located on the Colorado River.
They provide water for populations across seven US states in the south-western US, with around 40 million people getting some or all of their municipal water from the Colorado River.
The river also provides water for around 5.5m acres (22,258 square kilometres) of farmland across Colorado, Arizona, California and the other states in the river basin.
Experts tell Carbon Brief that climate change, population growth and over-consumption are all contributing to the current record-low levels of the reservoirs.
Record lows
At full capacity, Lakes Mead and Powell can hold a combined 68 cubic kilometres of water – enough to supply all household consumption in the contiguous US for nearly 1.5 years. However, the water level in both reservoirs has been declining for decades.
The chart below shows the water level of Lake Mead, in metres above mean sea level. The reservoir, which began to fill in 1935 following the construction of the Hoover Dam, has a “full pool” maximum capacity of 347.60 metres. The water level in Lake Mead reached a record low of 317.11 metres on 7 August.

The following chart shows the water level of Lake Powell, in metres above mean sea level. Lake Powell’s full-pool level is 1,127.76 metres.
While the reservoir reached its maximum capacity several times in the 1980s, it has not done so since. On 15 August, the water level in Lake Powell was recorded at a new record-low of 1,072.87 metres.

Both reservoirs have continued to decline in the days since breaking their respective records. The downward trend will largely continue in both lakes until next spring, when the snowpack in the mountains of the Upper Colorado River Basin begins to melt, says Dr Jack Schmidt, a senior research scientist at Utah State University’s Center for Colorado River Studies. He tells Carbon Brief:
“The big dilemma of the moment is that we’re only in the middle of August, and we have no assurance of what the coming winter will be. The only thing we can be sure of is that we will be depleting overall total basin reservoir storage from now until, roughly, early April.”
Compounding factors
The record lows across the two reservoirs are the result of several compounding factors, experts tell Carbon Brief.
Since the turn of the 20th century, the amount of water flowing along the Upper Colorado River has declined by about 20%. Research suggests that half of this decline can be attributed to human-induced climate change.
Most of the river’s streamflow comes from the snowpack of the Upper Colorado River Basin, which stretches across five western US states but is primarily located in Colorado and Utah.
This region has been gripped by a historic “megadrought” for more than a quarter of a century. Nearly half of the megadrought’s intensity over 2000-18 is attributable to climate change, according to a 2020 study.
At the same time, the increasing population in the US south-west has put added pressure on the Colorado River’s water supply. The number of people obtaining some or all of their water from the Colorado system has grown by 15 million (around 60%) since 1992.
Schmidt tells Carbon Brief:
“There’s an ultimate cause of the present water crisis, and there’s a proximate cause. The ultimate cause is a warming climate, a warming planet and a pretty clear correlation between warming conditions and decreased runoff in the Colorado River Basin.
“The proximate cause is that in this messy democratic republic of ours, big policy decisions that match the variability of the climate occur painfully slowly – with intense political negotiations – and only incrementally.”
On 31 July, the US Bureau of Reclamation, which manages water resources in the western US, released an environmental impact statement on its proposed post-2026 strategy for managing Lakes Powell and Mead. The strategy itself has not been released yet.
Schmidt notes that the statement does appear to give the Bureau flexibility to “respond to crisis” by reducing the delivery of water to several states. However, he adds:
“They acknowledge it won’t work if we just stay critically dry, and of course every climate model for the 21st century, especially with a continually warming planet, says that that’s exactly what’s going to happen.”
