(Bloomberg) -- France is seeking to reopen negotiations over a key Green Deal law in an effort to ensure a greater role for nuclear in Europe’s energy transition, a move fiercely opposed by Germany, leaving the talks in deadlock. 

The government in Paris has informed Sweden, which holds the EU’s rotating presidency, that it’s seeking changes to an agreement already brokered with other EU entities, according to officials with knowledge of the matter. Such a step would require revisiting talks with the bloc’s parliament and the European Commission.

Germany — which just shuttered its last nuclear plants in April — has teamed up with other member states to block the move, the people said, asking for anonymity because the discussions are private. Berlin favors approving the law in its current form as soon as possible, according to the Economy Ministry. 

The dispute pits Europe’s two largest economies against each other over the role of nuclear power as the region tries to speed the transition to a low-carbon economy while recovering from a historic energy crisis. The EU framework deal agreed in March would raise the region’s 2030 renewable target to 42.5% of total energy consumption, while providing a small role for nuclear.

Sweden is now seeking a solution acceptable to a weighted majority of member states before the end of its presidency on June 30. Any further delay would risk undermining the objectives of the Green Deal — the EU’s plan for carbon neutrality — at a time when the ambitious pace of the overhaul already faces pushback from some member states and industry groups.

The Swedish presidency said talks with France are ongoing, declining to disclose further details.

French President Emmanuel Macron, whose country relies on nuclear energy for the bulk of its electricity production, said this week that EU member states should retain their sovereign right to choose energy sources. The nation is betting on the production of hydrogen using power generated by its atomic plants to meet climate goals. 

“We want to create industrial partnerships in hydrogen and nuclear to foster job creation on our soil,” he said at a press conference in Bratislava. “We’ve inherited national energy mixes and now we are fragmenting the production of green, low-carbon hydrogen of the future and the energies of tomorrow. This is an aberration for Europe.” 

The French leader is set to discuss energy issues with German Chancellor Olaf Scholz over dinner in Potsdam near Berlin on Tuesday to try and come up with a common position.
