More than two years since Russia began its full-scale invasion of Ukraine, its gas is still flowing into Europe.

While the European Union has greatly reduced the amount of gas it imports from Russia, the hydrocarbon is still powering some European homes and businesses and boosting Kremlin revenues as a result.

When the war began, European leaders were forced to reckon with a long-established dependence on both Russian gas and oil. Gas was a particular problem, as in 2021, 34% of the EU's gas came from Russia.

Countries in Central and Eastern Europe were especially dependent. When the EU mooted a ban, German Chancellor Olaf Scholz was quick to voice his opposition. "Europe has deliberately exempted energy supplies from Russia from sanctions. At the moment, Europe's supply of energy for heat generation, mobility, power supply and industry cannot be secured in any other way," he said.

Vladimir Putin seized on this. Throughout 2022, Russia cut gas imports to Europe. European leaders fretted about a winter energy shortage. These fears were never realized, but crucially, they meant the EU never actually sanctioned Russian gas.

"It was never a sanction," says Benjamin Hilgenstock from the Kyiv School of Economics. "It was a voluntary decision by countries, and a smart one, to diversify supply and no longer be blackmailable by Russia," he told DW.

According to EU data, the share of Russian pipeline gas member states imported fell from 40% of the total in 2021 to about 8% in 2023. However, when Liquefied Natural Gas (LNG) is included — natural gas cooled down to liquid form so it can be transported by ship — the total share of Russian gas in the........
