ungary and Slovakia , which voted against the measure and Bulgaria , which abstained. Hungary said it plans to challenge the law at the European Court of Justice . The legislation was adopted through a reinforced majority , allowing it to pass without unanimous support. Hungary and Slovakia remain among the EU members most dependent on Russian energy and have sought to preserve closer relations with Moscow. Under the new rules, the EU will end imports of Russian liquefied natural gas (LNG) by the end of 2026 and pipeline gas by September 30, 2027. The deadline for pipeline gas may be extended to November 1, 2027, in exceptional cases where countries struggle to fill gas storage ahead of winter. Russia accounted for more than 40% of EU gas supplies before 2022, but that share had fallen to around 13% in 2025, according to the latest EU data. Despite the decline, several EU countries continue to purchase Russian oil, LNG and pipeline gas, raising concerns about ongoing financial flows to Russia’s wartime economy. The law bans companies from signing new Russian gas contracts and requires existing agreements to be terminated. Imports under short-term contracts signed before June 17, 2025, will be prohibited from April 25, 2026, for LNG and June 17, 2026, for pipeline gas. Long-term contracts must be phased out by the final 2027 deadlines. Companies that fail to comply could face fines of up to 3.5% of their global annual turnover. Last month, the EU’s five largest importers spent an estimated €1.4 billion on Russian energy, mostly gas and LNG, according to the Centre for Research on Energy and Clean Air, with Hungary the largest buyer, followed by France and Belgium. The European Commission said it plans to propose further legislation in the coming months to phase out Russian pipeline oil and reduce EU dependence on Russian nuclear fuel, as part of broader efforts to sever remaining energy links with Moscow.
