BRUSSELS — The European Union will step up efforts to diversify away from American liquefied natural gas following U.S. President Donald Trump’s threats to take control of Greenland, EU energy chief Dan Jørgensen said Wednesday.

Calling the events of recent week a “clear wake-up call,” Jørgensen said growing geopolitical instability — from Russia’s war in Ukraine to rising tensions with Washington — means the EU can no longer assume energy ties are immune from security shocks.

“These are very turbulent times,” Jørgensen told journalists at a briefing in Brussels. “What has made the situation more serious and complex is the strained relationship to the U.S. and the fact that we have an American president that does not exclude using force against Greenland,” he said.

The U.S. already supplies more than a quarter of the EU’s gas, up from just 5 percent five years ago, with dependence set to rise further as a total ban on Russian gas takes effect.

But Jørgensen said the Commission is now actively seeking alternative suppliers to the U.S. and plans to deepen energy ties with a range of countries in the coming months, including Canada, Qatar and Algeria.

“Canada for sure, Qatar, North African countries,” he said, adding that Brussels is also working to secure non-Russian sources of nuclear fuel for member countries that still rely on Moscow.

While stressing that Brussels does not want a trade war with Washington, Jørgensen acknowledged mounting concern inside the EU that it risks “replacing one dependency with another” after rapidly pivoting from Russian gas to U.S. LNG following Moscow’s invasion of Ukraine.

“It has never been our policy to start trading less with the U.S., and we don’t want trade conflicts,” he said. “But it is also clear that geopolitical turmoil … has been a wake-up call. We have to be able to take care of ourselves.”

The commissioner said he had not yet spoken with his U.S. counterpart since Trump’s remarks on Greenland, and said the EU has not set a formal threshold for how much U.S. LNG would be considered too much. For now, American gas remains “essential” to replace Russian supplies, he said.
