+2.72 °C — Romania's climate is changing faster than Europe's, and the bill is arriving from three directions at once
.png?width=1200)
Romania is living through climate warming faster than the European average, and the European Union has already set the price of the transition: climate costs now reach bills, harvests, budgets and bank balance sheets, not just reports.
This analysis brings together what has been measured, what has been decided in Brussels and Bucharest, and what can be anticipated. It answers four questions: how fast the climate is changing in Romania, through which channels the costs reach the economy, which financial scenarios are plausible to 2030, and what the Romanian state should do now.
The testable thesis: for Romania, the biggest risk of the next five years is not a single catastrophe but three bills arriving in the same window. The first comes from physical damage, almost all of it uninsured. The second comes from the carbon price for households, from 2028. The third comes from the adaptation investments that were not made in time.
What the measurements show
Europe is the fastest-warming continent: since the 1980s it has warmed twice as fast as the global average, according to the Copernicus service's European State of the Climate 2025 report. In 2025, at least 95% of European territory had above-average annual temperatures, and sea surface temperature was the highest on record for the fourth consecutive year. The report also notes that the east of the continent is warming faster than the west.
Globally, 2025 was the third-hottest year on record, with a mean temperature 1.47 °C above the pre-industrial level, and the three-year average for 2023–2025 exceeded the 1.5 °C threshold for the first time, according to Copernicus and the WMO. The Paris Agreement threshold refers to 20-year averages, so it has not yet been formally crossed, but it is no longer a distant boundary.
In Romania, the National Meteorological Administration reported a 2024 mean temperature of 12.99 °C, 2.72 °C above the 1991–2020 normal, the hottest year since 1901, according to TVR Info. 2025 was the fourth hottest, at 11.95 °C and a deviation of 1.22 °C, and 2012–2025 is the hottest 14-year run on record, according to Economica.net. In July 2025, Calafat recorded 43.4 °C, and seven months of the year were affected by drought.
Where the bill already shows
The impact is no longer a projection but a series of measured events, each with its own cost. The table brings together the most recent verifiable figures for Romania.
| Channel | What was measured | Source |
|---|---|---|
| Health | More than 4,900 heat-related deaths in summer 2024, fifth in Europe in absolute terms, out of 62,775 across the continent | ISGlobal, Nature Medicine |
| Wildfires | 134,370 hectares burned in 2025, against an annual average of about 23,000; the EU set a record of 1,079,538 hectares | EFFIS, European Commission |
| Floods | Storm Boris, 13–14 September 2024: 7 dead, more than 6,000 homes affected, 148 mm of rain in 24 hours in Galați | IFRC, ReliefWeb |
| Agriculture | 2024 cereal harvest: 17.87 million tonnes, the lowest in ten years (wheat 9.29 m t, maize 5.99 m t) | INS |
| Energy | Hidroelectrica, 2025: net output of 11,847 GWh (−15%), external power purchases +175%, net profit 3.3 billion lei (−20%) | Preliminary results, BVB |
| Cumulative losses | About 14.6 billion euros of losses from extreme weather in 1980–2021, eighth in the EEA area | European Environment Agency |
Sources, in table order: ISGlobal, Romania Insider, on EFFIS data, ReliefWeb, Romania Insider, on INS data, Hidroelectrica's preliminary report and the EEA table as published by the Slovenian environment agency. The European Environment Agency puts losses for the whole EU at 822 billion euros in 1980–2024, a quarter of them in 2021–2024 alone.
The causal chain: why Romania is more exposed than average
The cause. Romania sits at the intersection of two trends: the faster warming of Eastern Europe and the northward spread of a Mediterranean climate that is drier in summer. South-eastern Europe is, in the European Environment Agency's 2024 climate risk assessment, one of the areas where adaptation is not keeping pace with the risks. The agency identified 36 major risks for Europe, 21 of which require immediate action, according to the EEA.
The mechanism. Heat and drought hit three mutually dependent sectors at once. Less water in the Danube and in reservoirs means less hydropower, hence more expensive power imports, as Hidroelectrica's 175% increase in external purchases shows. Drought cuts the harvest, hence agricultural exports and rural incomes. And heatwaves raise power demand for cooling precisely when hydro output falls.
The financial effect. The damage reaches the state. More than half of the losses from extreme events are uninsured in most European countries, and Romania's coverage is among the lowest. Only about 19% of homes had the mandatory catastrophe insurance at the end of 2021, according to ASF data cited by Romania Insider. When homes are uninsured, rebuilding them becomes a budget expense, in a year when the budget already runs a large deficit.
The counter-hypothesis. An alternative reading says we are seeing volatility, not a trend: after the weak 2024 harvest, 2025 brought forecasts of a good wheat crop, and farm output partly recovered. The counter-hypothesis is partly true. Good years have not disappeared, but the gap between good and bad years is widening. And for budgets and banks, what matters is precisely the bad year, not the average.
What Europe has decided and what comes next
On 10 February 2026, the European Parliament adopted the target of a 90% net emissions cut by 2040 compared with 1990, by 413 votes to 226 with 12 abstentions. Romania's delegation voted 20 in favour, 8 against and 2 abstentions, and 3 MEPs did not vote, according to the roll-call record on HowTheyVote.eu (data under the ODbL licence). The compromise allows up to 5 percentage points to come from international carbon credits from 2036 and postponed by one year, to 2028, the launch of the carbon market for buildings and transport, ETS2, according to ICAP.
ETS2 is the piece that reaches households directly. For the first years, a mechanism releases extra allowances if the price exceeds 45 euros per tonne, in 2020 prices. Using standard emission factors, we calculated what this threshold means at the BNR rate of 5.3373 lei per euro on 12 October 2026. The calculation excludes VAT.
| Fuel | Emissions | Cost at €45/t CO₂ | In lei |
|---|---|---|---|
| Petrol | 2.31 kg CO₂/litre | €0.104/litre | 0.55 lei/litre |
| Diesel | 2.68 kg CO₂/litre | €0.121/litre | 0.64 lei/litre |
| Natural gas for heating | 0.202 kg CO₂/kWh | €0.0091/kWh | 0.049 lei/kWh |
For a household that uses 10 MWh of gas a year and a thousand litres of petrol, that means about 1,040 lei a year more, excluding VAT, if the price stops at the threshold. On the existing carbon market, ETS1, allowances traded in August 2026 between 82 and 84 euros per tonne, and the official April–September average was 78.93 euros, according to CarbonCredits.com. The ETS2 price will not necessarily be as high, but the 45-euro threshold is not an absolute cap.
Compensation comes through the Social Climate Fund: Romania is set to receive about 6 billion euros in 2026–2032, or 9.25% of the fund, according to Balkan Green Energy News. The national plan was in public consultation in November 2025. We found no confirmation that the Commission has approved it, and without an approved plan the money does not reach households before the carbon price reaches their bills.
What Romania has decided and what remains suspended
The National Integrated Energy and Climate Plan, updated in 2024, sets a 38.3% share of renewables in gross final energy consumption by 2030, according to HotNews. The Eurostat series collected by olivLaw shows 24.3% in 2019 and 25.6% in 2025: six years for a gain of 1.3 points. To hit the target, the pace would have to rise to about 2.5 points a year, more than ten times faster than so far.
The coal exit is legally blocked. On 5 August 2026, with 180 votes in the Chamber of Deputies, Parliament adopted an amendment to the decarbonisation law that bans the closure of any coal capacity before replacements come online, according to Digi24. President Nicușor Dan sent the law to the Constitutional Court on 26 August, according to the Presidential Administration. As the recovery plan closed on 31 August, Prime Minister Ilie Bolojan said Romania would lose up to 100 million euros for the decarbonisation milestone, according to Spotmedia. As of 12 October we had found no ruling from the Court.
The two large low-emission energy projects are moving, but not on a short horizon. The Neptun Deep field, an investment of up to 4 billion euros, is due to deliver first gas in the first half of 2027 and reach about 8 billion cubic metres a year, according to Romania Insider. The Doicești small modular reactor project received its final investment decision on 12 February 2026: six NuScale modules of 77 MW each, at an estimated total cost of about 4.9 billion dollars, according to Nuclearelectrica.
The debates that matter
The 2040 target, ambition or illusion. Supporters say a fixed target gives investors predictability and that delay makes the transition more expensive. Critics, including four states that voted against in the Council (Czechia, Hungary, Poland and Slovakia, according to EUSTAFOR), say the target is too costly for economies with heavy industry. The compromise with international credits and periodic reviews shows that both camps won something, but also that the target can be renegotiated.
ETS2, social justice or price signal. Lower-income countries that heat with gas or wood, Romania among them, fear an energy-price shock for poor households. The counter-argument says that without a carbon price, emissions from transport and buildings, the only ones that have stagnated, will not fall. What matters for Romania is the order: the Social Climate Fund money must arrive before the bill, not after it.
Coal, security or delay. The camp that voted for the amendment says a plant closed before its replacement endangers the safety of the power system. The opposing camp says an open-ended delay blocks European funds and keeps the country's largest emission sources running. Both arguments contain some truth. The technical solution, a strategic reserve for a few units with a clear deadline, already exists in the timetable negotiated with the Commission.
Trade and agriculture. The EU–Mercosur trade agreement has applied provisionally since 1 May 2026, even though the European Parliament had first asked for the Court of Justice's opinion, according to White & Case. For Romanian farmers, who already carry the cost of drought, import competition and new environmental requirements add up in the same operating account.
Three scenarios for Romania to 2030
| Scenario | What it assumes | Financial impact | The signal that confirms it |
|---|---|---|---|
| Delayed adaptation (baseline) | Extreme years every two to three years, ETS2 from 2028, the Social Climate Fund partly used | Volatile annual damage, mostly uninsured; the carbon cost reaches households before the compensation | The Social Climate Plan still unapproved by mid-2027 |
| Double shock | A year like 2024 (heat and drought) coinciding with the ETS2 launch and high energy prices | Simultaneous pressure on inflation, on the trade balance (energy and food imports) and on the budget (compensation) | Hydro output below the 2025 level and a cereal harvest under 18 million tonnes in the same year |
| Accelerated adaptation | European money contracted on time, mandatory insurance enforced, irrigation and grids modernised | Higher upfront cost, but smaller losses in extreme years and access to funds that would otherwise be lost | Renewables share rising by more than 2 points a year and higher home-insurance coverage |
We attach no numerical probabilities to the scenarios, because they are not events with a resolution date. The testable probabilities are in the predictions table below. The baseline seems most likely to us because it describes the current trajectory. It would be refuted by a quick approval of the Social Climate Plan and a visible acceleration of investment in renewables and irrigation.
The financial channels and our assumptions
Climate risk reaches markets through five channels. Energy: hydro output varies with dry years, and companies buy power from abroad when water is short. Agriculture: weak harvests cut exports and raise farms' credit risk. Insurance: low coverage shifts damage onto the budget. Banks: the National Bank estimated that more than 40% of the firms generating gross value added are exposed to climate risks, and that the ten largest banks hold 86% of the exposure to significantly exposed firms, according to a 2023 presentation reported by Financial Intelligence. The budget: compensation, energy subsidies and lost European funds.
The analysis rests on four assumptions. First: the frequency of extreme years in south-eastern Europe keeps rising, in line with the trend measured since 2012. Second: ETS2 starts in 2028 with no further delay. Third: home-insurance coverage does not rise quickly without a policy change. Fourth: European climate funds remain the main source of adaptation finance. If any of them fails, the scenarios shift. Especially the second: another ETS2 delay would cut the short-term bill, but also the pressure to invest.
What Romania should do
First, the money before the bill. The Social Climate Plan must be approved and implemented before 2028, with clear targets for vulnerable households: home insulation, replacing old stoves and public transport in small towns. Otherwise the carbon price becomes a tax on poverty, not an incentive to invest.
Then, insurance that actually works. Mandatory home insurance has existed since 2008, but without real enforcement. Broader coverage, with penalties or by tying the policy to other public services, shifts the risk from the budget to the market, as happens in other states.
Water as critical infrastructure. Irrigation, water retention and drought monitoring have become economic policy, not just farm policy. Southern Oltenia, the area most exposed to desertification, should be the first target of adaptation funds under the National Strategy on Adaptation to Climate Change 2024–2030.
A coal timetable that stops moving. Romania needs a limited strategic reserve for system safety, but with a fixed deadline, so that European funds are no longer put at risk in every parliamentary session.
Public health in heatwaves. More than 4,900 heat-related deaths in a single summer show that response plans, with cool spaces, early warnings and care for the elderly, save lives at low cost.
Better data. Romania publishes no official, annual and complete estimate of the damage from extreme events. Without it, neither the budget, nor the banks, nor the insurers can measure the risk they carry.
What olivLaw will track from now on
Climate change is not a separate topic in our models but a factor that moves other numbers: food inflation, energy prices, the trade balance and budget execution. So we will track it through public indicators, not our own estimates. We already have the Eurostat series on inflation and the renewables share, the BNR exchange rate and the European Parliament's votes on climate files. We will add the European climate calendar (the 2040 target reviews, the ETS2 launch, the Social Climate Fund deadlines) and link our economic forecasts to extreme years when we write about them.
The data we want to collect systematically, from public sources: monthly temperature anomalies and drought indices (ANM and Copernicus), burned areas (EFFIS), Danube flow and hydro output, the carbon allowance price, harvest estimates (European Commission and INS), home-insurance coverage (ASF) and the annual losses reported by the EEA. We will use them only with the source in plain view, so that every figure in our analyses can be checked.

Method, definitions and figures
Temperatures. Romania's deviations are those reported by ANM against the 1991–2020 climatological normal. Global deviations are those reported by Copernicus against the 1850–1900 pre-industrial period. The two baselines are not directly comparable.
The ETS2 calculation. The emission factors are the standard values used in emission inventories: 2.31 kg of CO₂ per litre of petrol, 2.68 kg per litre of diesel and 0.202 kg per kWh of natural gas. The 45-euro-per-tonne threshold is expressed in 2020 prices. The exchange rate is the BNR reference rate of 12 October 2026, from the daily series collected by olivLaw. The calculation excludes VAT and retail margins.
Our own data and the votes. The renewables share comes from the Eurostat series collected by olivLaw. The European Parliament votes are those in the roll-call records published by HowTheyVote.eu, under the Open Database License. Probabilities are editorial estimates in bands of at least ten percentage points.
Limits of this analysis
Several figures come from press summaries of official reports, not from the full documents. The limit applies mainly to the heat-related deaths, the burned areas and the harvest. There is no recent official estimate of annual damage for Romania. The EEA figure covers 1980–2021. The home-insurance coverage figure is from 2021, the most recent public one we found. We found neither the CCR ruling on the decarbonisation law nor confirmation that the Social Climate Plan has been approved.
The diagnosis would be refuted by two or three consecutive years without major extreme events in Romania, by another ETS2 delay accompanied by rising private investment in adaptation, or by a rapid increase in insurance coverage. The natural reassessment comes in January 2027, with the annual climate reports from ANM and Copernicus.
