Europe and the UK have become heavily dependent on US liquefied natural gas (LNG) after reducing reliance on Russian pipeline gas. This shift is due to the war in Ukraine and sanctions on Russia. A study by the Clingendael Institute, Ecologic Institute, and Norwegian Institute of International Affairs reveals that US LNG imports to Europe rose 61% in 2025 and 485% since 2019. Now, US LNG makes up 59% of Europe’s LNG imports. In the UK, 33% of gas is imported from Europe, with 68% of its LNG imports coming from the US. Russian pipeline gas, which made up 60% of European gas imports in 2019, dropped to just 8% by 2025. Professor Kacper Szulecki from the Norwegian Institute warned, "The US national security strategy of 2025 explicitly frames energy exports as a way to project power." Szulecki added that low gas reserves and potential cold winters could cause a dramatic energy crisis. Despite tensions, the EU has no real alternative to US gas and is even considering ending trade deals with the US over Greenland tariffs. Raffaele Piria of the Ecologic Institute said the UK faces the same energy risks as Europe because it remains connected to the European gas market. He noted, "Historically, interferences by the US government in gas markets to exert pressure on Europe were considered unthinkable. In the current geopolitical context, this assumption is questionable." The report concludes that Europe must act, stating, "Energy – particularly gas – exports increasingly function as a tool of strategic leverage." It urges Europe to speed up its switch to renewable energy sources to reduce this vulnerability.
