BRUSSELS ― António Costa is supposed to be the dealmaker who brings European leaders together. Increasingly, his efforts are going unrewarded.

At a summit of the bloc’s national leaders on Thursday, Costa — who, unlike most of the EU’s current big beasts, is a Socialist — suffered his most stinging criticism since taking the role of European Council president nearly two years ago. The ire centered on his handling of unrelated negotiations over curbing energy prices and the EU’s next seven-year budget.

Governments were looking for both debates to show signs of progress at the two-day gathering, which was scheduled to continue on Friday. What they got was, at best, stalemate ― at worst, mounting division. And a day of talking that dragged on for 14 hours with little to show for it.

The longer budget negotiations last, the “more difficulties we will have,” Finnish Prime Minister Petteri Orpo told POLITICO. “So we have to work to find a solution this year. I understand very well that it is difficult. A huge challenge.”

The stakes could barely be higher. The EU is desperate to ease the cost of living crisis and get a deal on the budget before national elections next year make finding an agreement much tougher. Disunity between the bloc’s 27 members looks even starker when Donald Trump makes moves to take Russia’s side in the Ukraine war, the economy is struggling to match the might of China and anti-EU nationalists get closer to power in Europe’s biggest capitals.

All 16 diplomats and officials who POLITICO spoke to for this article were granted anonymity to allow them to speak on a sensitive issue. They were all either in the summit room on Thursday or were immediately briefed by leaders who were. While most were critical of Costa, others spoke more positively.

Costa’s spokesperson declined to comment.

Bogged down

Costa, a former Portuguese prime minister, is appointed by leaders to chair their summits and corral them into agreement. As Brussels Playbook reported on Thursday, EU officials judge he’s entering a defining period of his presidency, racing against time to overcome huge divisions on the budget. He is widely expected to push for reappointment for a second two-and-a-half-year term next year, officials said.

Thursday’s summit was dominated by discussions unraveling on the second phase of the bloc’s carbon pricing regime, known as ETS2.

The showdown over the Emissions Trading System — both the current one, and the second iteration which is already legislated and will put a carbon price on heating and transport from 2028 — became so bogged down it forced Costa to cancel the summit’s planned press conference and delay further talks until after dinner, because they had become a “mess,” three EU diplomats told POLITICO.

With German Chancellor Friedrich Merz incensed by what Berlin saw as his Italian counterpart Giorgia Meloni’s intransigence, fiery negotiations pitted a coalition made up of Germany, Spain, France, Portugal, the Nordics and the Netherlands against a stubborn bloc of Italy with Hungary, Czechia, Slovakia and Poland (known as the Visegrád Four). Rome and the V4 group wanted the EU to postpone ETS2 because of the burden it would place on energy bills, according to five diplomats.

Leaders were fuming at Costa for allowing talks to go off the rails, two EU diplomats from different member countries said. While the pre-summit conclusions didn’t point to any rethink of ETS2, the countries tried to unpick the legislation in the summit room, leaving Costa flustered, one of them said.

Costa “wants to have conclusions ready from [pre-summit meetings of ambassadors] and not to open them during EUCO,” the diplomat said. “He is not a fan of drafting on the spot.”

Another said there was “huge frustration,” calling the tug-of-war over the wording of the energy policy “insane chaos.”

“They just went on with Italian drafts and disregarded texts that were handed in before by others, seemingly not understanding the political nuances of the whole ETS discussion,” they added.

Another accused Costa of “losing control of the room,” saying he had failed to keep track of proposed amendments and present them to EU leaders in time for the discussions. As a result, leaders were left debating without them, contributing to negotiations going on past midnight.

One diplomat and one EU official separately compared Costa with his immediate predecessors, Charles Michel ― who governments frequently criticized for a lack of dealmaking know-how ― and Donald Tusk, who enjoyed broad support throughout his term in office.

Costa performed “worse than Charles Michel” on Thursday, the diplomat said. The official said “there is frustration that things are not being dealt with a bit more Tusk-style.”

Honest broker

The annoyance went beyond the energy debate. While governments weren’t expecting a breakthrough on the EU budget on Thursday, they have started raising questions about Costa’s handling of that topic too.

Costa is determined to secure an agreement by the end of the year. In his job, the Council president must act as a honest broker and facilitate a deal among 27 governments.

Northern EU countries are worried he’s favoring southern countries, according to a further four EU diplomats.

One EU diplomat accused Costa of being two-faced and not acting as an honest broker in the budget negotiations.

Another diplomat, from a country that wants the budget to be smaller, said: “Costa personally and politically belongs to the other camp.”

“There is some skepticism on how he will take the process further from here,” they said. The so-called frugal countries are calling on Costa to propose further cuts ahead of a special EU summit on the budget that was confirmed Thursday for Nov. 26.

‘Superb deal maker’

Many governments still believe Costa may succeed over the long term. Even those who acknowledge that his honeymoon is over ― a period when he was roundly praised for being a safe pair of hands and avoiding diplomatic faux-pas ― retain faith in him.

Belgian Prime Minister Bart De Wever defended Costa as “capable” and “shrewd” after the first day of the summit — praising the Council president for largely avoiding drafting on the day, unlike Michel.

Costa “avoids negotiation about the wording on the table which happened all the time under his predecessor and which annoyed the hell out of everybody because then you are here until three o’clock to discuss about syllables, commas and words that the next morning you cannot see the difference anymore,” De Wever said. “You don’t even know anymore what you are negotiating about.”

Other diplomats said the disarray wasn’t Costa’s fault, and blamed the leaders who tried to unpick the energy legislation, notably Meloni. “He did not want to reopen the conclusions, it was the V4 and Italy who did so,” one said. “I don’t see what he could have done differently.”

Another EU official defended the sheer difficulty of the task faced by the Council president. “Discussing drafting at leaders’ level is not the most straightforward thing in general.” On energy, the official said leaders wanted to have “proper consideration” of the different proposals by countries, which had “opposing interests.”

One of the diplomats more critical of his political leanings on the budget said Costa was “impeccable” in his behavior. “He’s a superb deal maker.”

The next few weeks will show how true that turns out to be.

BRUSSELS — It was meant to be a debate on how to curb Europe’s soaring energy prices.

But the first session of talks at an EU leaders’ summit in Brussels Thursday quickly descended into a three-hour fight over whether the EU should put a carbon price on driving cars and heating buildings.

The delay got so bad, the roast veal and fig tartlet lunch awaiting European leaders was driven well into the afternoon.

Countries including Italy, Poland, Czechia and Hungary called for ETS2 — an already-legislated law that will put a carbon price on heating and transport from 2028 — to be delayed for two more years. Estonia suggested it could be scrapped altogether.

The push was rejected by a majority of the bloc, with several EU diplomats telling POLITICO it was, as one put it, an “unacceptable” offer. Another said the ETS2 launch date would never be changed. But the debate reflects a growing sense from right-leaning governments that the EU’s ambitious green agenda runs against their push to bring down energy costs. 

While the main topic of today’s discussion was ETS2, its predecessor, the Emissions Trading System — which puts a price on carbon emissions from factories and power plants — was arguably the real target.

Put together, these two emissions trading schemes will be the EU’s most powerful policy tool for bringing down planet-warming emissions.

A proposed reform of the original ETS is currently being debated in the European Parliament and in the Council of the EU. Italy and Poland have been leading a gang of 10 member-countries which have been railing against the ETS since American and Israeli bombs started falling on Iran in March. 

What they want is for the European Commission’s July review of the ETS to be further weakened, even though the proposal already softens carbon restrictions over the next decade to give industry more time to invest in cleaner production methods.

But by framing the ETS as a scourge on household bills, both Warsaw and Rome have found ready audiences at home and abroad. On Monday, hours before a meeting of EU environment ministers convened in Luxembourg, Poland led a meeting of member countries with concerns on the ETS. Their gang, which originally counted 10 countries in March, had now grown to 16.

While Italy and Poland did manage to get Czechia, Slovakia, Hungary and Greece to back their ask for a “reassessment of the ETS2” and to “further postpone its entry into force until at least 2030,” inside the room of European leaders the position mostly fell flat.

Five EU diplomats granted anonymity to discuss the ongoing negotiations said Nordic countries and the Netherlands were firmly against changes to ETS2 — a position backed by France and Germany.

But Paris and Berlin’s long-term reliability as ETS defenders is in doubt. French President Emmanuel Macron and German Chancellor Friedrich Merz both face threats from the far-right, where the ETS has become a dirty word.

Germany’s far-right Alternative für Deutschland, which is no fan of the ETS, is politically ascendant, having won the largest share of votes in two regional elections in September. In France, with elections only months away in 2027, Marine Le Pen’s far-right National Rally is leading in the polls. 

How Le Pen would deal with the ETS isn’t certain, but Jordan Bardella, the French far-right lawmaker and rising star of National Rally, offered a clue  in recent comments.

“ETS: three letters, an acronym that reeks of detached bureaucracy, with one question that keeps coming up: who’s going to pay?” he said to European Parliament in May.

BRUSSELS — Three of the European Parliament’s biggest political groups say they will fight an EU proposal to relax carbon pricing rules, opening a rift that could push conservative lawmakers to side with the far right to weaken the bloc’s climate ambition.

The center-left Socialists and Democrats, the centrist Renew Europe and the Greens all said in recent days that they would try to preserve an ambitious path to net zero under the Emissions Trading System, forcing heavy industry to cut planet-warming emissions faster than Brussels proposes.

That puts them at odds with the center-right European People’s Party, Parliament’s biggest group, which broadly supports the European Commission’s proposal.

For years, those four groups have worked together in Parliament to pass legislation that strikes a political middle ground, shunning collaboration with the far right. The sometimes uneasy alliance has ensured consistent, bipartisan support for the ETS, Europe’s most powerful tool for reducing greenhouse gas emissions.

But now, a reform of the landmark cap-and-trade scheme, unveiled by the EU executive in July, looks set to become a bellwether in an era when, increasingly, the center no longer holds.

The EPP is steering Parliament’s work on the proposed ETS revision through veteran German lawmaker Peter Liese, who wants to find a deal that satisfies everyone.

“I don’t want the Venezuelan majority. It’s against my convictions, but it is also not possible because nobody would see [Marine] Le Pen, the Austrian far-right FPÖ or the German extreme-far-right AfD voting for any ETS proposal,” he told POLITICO in September, using the informal term for a controversial alliance of center-right and far-right groups.

Instead, Liese, who maintains close ties with Dutch S&D lawmaker Mohammed Chahim, said he wanted “the broadest possible coalition,” including the right-wing European Conservatives and Reformists as well as “the Greens, The Left, if they want.”

But new amendments filed last week by the S&D, the second-largest group in Parliament, as well as the Greens and Renew, point to major schisms over key aspects of the ETS reform. The biggest divide concerns the so-called linear reduction factor, the mechanism that determines how quickly the supply of pollution permits shrinks each year. 

Under the current trajectory, the total cap on carbon emissions for all sectors covered by the ETS falls slightly each year, and would reach zero around 2039 or 2040. At that point, ETS sectors — which include power generators, steelmakers and chemical manufacturers — would no longer be able to emit any carbon dioxide at all. 

Liese’s proposal would push that date into the 2040s, in line with the Commission’s original pitch in the summer. But the three other centrist or left-leaning groups oppose the plan and have tabled nearly identical amendments that would keep the rates high until the end of next decade and bring about quicker industrial decarbonization across Europe. 

Though the percentages between the warring groups appear tiny, they translate into millions of additional tons of CO₂ emissions and expose a growing political gulf. S&D, the Greens and Renew are fighting to preserve Europe’s climate ambitions, while the EPP is increasingly sympathetic to the concerns of the chemicals and metals industries, both of which have been vocally critical of the ETS. 

But just as the chances for a centrist compromise dim, Liese has another possible route.

Memories of fascism in the early twentieth century once discouraged mainstream political groups from working with the far right. That firewall appeared to erode when talks with centrist allies collapsed in 2025 over the first omnibus package governing certain environmental reporting rules. The EPP turned to the right-wing ECR and the far-right Patriots for Europe and Europe of Sovereign Nations to secure a deal, paving the way for similar alliances in the future.

On the ETS, there is a growing risk that it could happen all over again.

Czech lawmaker Alexandr Vondra of the ECR recently floated the possibility of working with Liese to secure a deal backed by his right-wing group during a parliamentary debate on the ETS.

“I would address here specifically EPP because it holds the key to the success of the reform of the ETS system,” he said, before laying out a list of industry-friendly demands that included a much looser trajectory to zero emissions. “If so, count me and my group in.”

Amendments tabled by Vondra this week and seen by POLITICO reflected a similar willingness to work with the EPP and limited regard for emissions reductions. If Liese does decide to shift his compromise to the right and cashes in on ECR votes, it could also quell problems within his own party.

The Polish, Spanish and Italian branches of the EPP are all unhappy with what they see as Liese’s overly climate-friendly proposal, according to three parliamentary insiders. Recent votes in Parliament on the Carbon Border Adjustment Mechanism, the bloc’s carbon levy on imports that works in tandem with the ETS, exposed fractures within the group, with portions of the EPP supporting right-wing groups or abstaining on a key provision of the legislation.

But how willing far-right groups will be to play ball with the EPP remains to be seen. 

The Europe of Sovereign Nations group — whose members include Germany’s far-right Alternative für Deutschland — is hostile to the ETS and wants it totally abolished. But the Patriots — whose members include France’s National Rally — might provide Liese with an opening: the group generally calls for the policy to be slowed to a halt, especially the upcoming ETS2, as it does all Green Deal legislation. French far-right lawmaker and rising political star Jordan Bardella said as much in a speech to Parliament in May.

“ETS: three letters, an acronym that reeks of detached bureaucracy, with one question that keeps coming up: who’s going to pay?” he said.
