The European Union’s top court has upheld the European Commission’s decision to classify investments in natural gas and nuclear power as sustainable finance. The ruling follows a challenge by Austria, which raised safety concerns and uncertainty over nuclear waste disposal. The Commission argued that both gas and nuclear energy have a role in the transition to a net‑zero carbon future.
In 2022, the Commission defied protests from environmental campaigners and internal dissent by adding gas and nuclear power to its sustainable finance taxonomy—a classification system for environmentally friendly economic activities. Austria, fiercely anti‑nuclear since a 1978 vote blocked its only nuclear plant from operating, contested the decision in court, emphasizing safety risks and waste‑management issues. However, the Court of Justice of the European Union (CJEU) found that the Commission had not exceeded its authority and was entitled to its view. The CJEU stated that, under certain conditions, economic activities in the nuclear and fossil‑gas sectors can substantially contribute to climate‑change mitigation and adaptation.
Austria’s climate minister, Norbert Totschnig, called the decision “very regrettable,” and environmental groups have also challenged the Commission’s definition of natural gas and nuclear power as “green” energy sources. The debate highlights the contested role of these fuels in the EU’s transition to a low‑carbon economy. Achieving the EU’s net‑zero target by 2050 will require significant investment in clean‑energy technologies, and the taxonomy is intended to guide investors toward sustainable projects. The CJEU’s ruling reinforces the Commission’s approach to sustainable finance and provides clarity for investors, but discussion over the place of natural gas and nuclear power in the energy transition is likely to continue. As the EU advances its climate goals, the taxonomy will remain a crucial tool shaping sustainable investment.
