Ukraine’s decision to end the gas transit deal with Russian energy giant Gazprom has been hailed by President Volodymyr Zelensky as one of Moscow’s biggest defeats. Today, the transit of Russian gas is zero.

With transit routes through Ukraine for Russian gas cut off, a few EU countries now need to rethink their gas supply. For others – including Germany and Switzerland – the impact will be minimal.

Russia’s share of the EU pipeline natural gas market dropped sharply to about 8% in 2023, according to data from the EU Commission. The Ukrainian transit route served EU members Austria and Slovakia, which long got the bulk of their natural gas from Russia but have recently scrambled to diversify supplies.
