Prices for LNG — a chilled, liquid form of gas that can be transported via sea tankers — are tightly linked to prices for Europe’s natural gas delivered by pipelines.
Gas prices spiked to a record high of around €345 ($367) per megawatt hour in August, after Moscow reduced gas deliveries to the continent.
TTF gas futures fell back 5% on Monday to hit €107 ($114) per megawatt hour.
Other EU measures have included gas storage requirements and a price cap of $60 a barrel on seaborne Russian oil.
Germany, the bloc’s biggest economy and one of its largest importers of natural gas, had been the most notable holdout before Monday’s announcement.
