The European Commission, which is the executive branch of the European Union (EU), has included nuclear energy in its draft ‘Complementary Designated Act’ (CDA) of the EU ‘Taxonomy Regulation’ regarding green energy. The draft CDA, which had previously been leaked to the media, has now been formally released to EU member states for consultation. (The draft CDA also includes natural gas as a green energy source, but only on a transitional basis. This means that natural gas will have to be phased out as more sustainable energy sources become available. The terminal date for the construction of taxonomy-compliant natural gas energy projects is December 31, 2030.)
