The European Union is moving closer to banning all imports of Russian oil and natural gas more than three years after Moscow launched its unprovoked, full-scale invasion of Ukraine.

The European Commission on Tuesday proposed legally-binding measures to cut off the European Union's imports of Russian gas and liquefied natural gas imports by the end of 2027, which would end decades-old energy relations with Europe's former top gas supplier.

The European Union’s proposed ban on all Russian gas by the end of 2027 sets the stage for heated debate, with some member states nervous it will boost energy prices and cost companies millions of euros in legal fees.
