Under a move labeled the EU Taxonomy, today's vote reclassified the energy sources as both green and sustainable. 

Claude Tourme, Luxembourg's Minister of Energy, expressed his disapproval of the decision on Twitter, saying, "I deeply regret that today 

@Europarl_EN failed to object to the delegated act under the #EUTaxonomy, allowing #gas & #nuclear to be part of the EU sustainable finance policy." He stated that the country would seek legal action against the decision. 

RePlanet, a climate change activist group in Europe, praised the move by the EU's leadership, saying, "Science wins! … This is a huge win for science and for climate action. Well done to all those who campaigned for this outcome. Together we can build a better future."

In February, the EU said that nuclear and natural gas energy plants could be counted as "green energy" under controversial EU plans related to climate change.

The European Commission says it has decided that both types of energy can classify as "sustainable investments" if they meet specific targets.

The move divided the EU and has been fiercely opposed by some members.
