Ten EU countries call for nuclear to be marked ‘sustainable’
Ten of the 27 member countries of the European Union recently sent a letter to the European Commission calling for nuclear power to be labeled as sustainable in a new rulemaking that pertains to powering data centers and artificial intelligence.
While the EC’s decision could have significant impact on the future deployment of nuclear across the continent, this call to action also represents a broader positive reconsideration of nuclear power in Europe in recent years.
