A shortage of gas this winter could lead to a serious economic crisis in Europe, warned German Vice Chancellor and Economics Minister Robert Habeck.

"Over the winter, there is a threat of a scenario where reductions actually have to be imposed. In my opinion, that would lead to a severe economic crisis in Europe and in Germany, and that must be avoided at all costs," Robert Habeck said Monday.

"We are not there yet, but in order not to get there, we need decisive, joint, solidarity-based and, above all, very rapid action."

"A supply crisis in one country leads to an economic crisis in another. We are committed and dependent on solidarity in this case."

Habeck supported the US initiative to impose a price cap on energy imports from Russia, subject to the participation of a sufficient number of countries. Rising energy prices have become a heavy burden on consumers and industry, Habeck said, and he urged industry and consumers to conserve gas to prepare for winter.
