Europe is concerned about the Biden administration's decision to delay approval of new liquefied natural gas terminals in the United States. This move, seen as a win for environmental groups, has raised worries about future energy supplies for U.S. allies and trade partners. The potential impact on global gas supplies, especially in Europe, is causing uncertainty and concern, given the region's recent energy shock after Russia's invasion of Ukraine. The surge in U.S. gas exports to Europe has been crucial in reducing Europe's reliance on Russian gas, and any restrictions on U.S. gas supplies are seen as a significant concern.
