The European Union’s legal stance on classifying nuclear energy and natural gas as part of its green economy remains unchanged after a court decision, potentially shaping the future flow of climate funds amid ongoing division among member states.

The European Union’s legal stance on classifying sustainable investments hasn't really changed much recently, even after a court decision that basically confirmed nuclear energy and natural gas can be part of their green economy framework. The EU General Court dismissed Austria’s legal challenge against the European Commission’s 2022 regulation, which had labeled certain nuclear and fossil gas activities as transitional measures to help meet the EU’s climate neutrality target by 2050. What’s important here is that this ruling keeps the door open for significant funding to flow into projects involving these energy sources, despite the ongoing debates about how “green” they really are.

Austria, backed by Luxembourg, made the case that including nuclear and natural gas in the EU taxonomy might amount to “greenwashing,” and in effect, could divert investments away from genuinely renewable sources such as wind, solar, and hydro. Austria, which doesn’t currently run any nuclear plants and has traditionally taken a stern stance against nuclear power, challenged this move on the basis that nuclear energy conflicts with the “do no significant harm” principle. They pointed out concerns like radioactive waste, the risk of accidents, and the carbon-heavy processes involved in mining uranium and preparing fuel as reasons why nuclear shouldn’t be classified as sustainable. The country’s environment minister back then, Leonore Gewessler—who’s now the parliamentary leader of Austria’s Greens—said that this classification was sending a “disastrous signal” to the EU, potentially weakening the clarity of green standards and leading to public and private funds being directed toward technologies she considers risky, expensive, and incompatible with the wider goal of a green transition.

But the court’s ruling basically said that the European Commission was acting well within its authority. It recognised that, under certain conditions, activities related to nuclear power and natural gas could play a significant role in fighting climate change by helping with mitigation and adaptation efforts. The court highlighted that nuclear energy produces very low greenhouse gases during operation, and since renewable options still aren’t at a large enough scale, including nuclear as a transitional solution makes sense. Similarly, although natural gas isn’t entirely carbon-neutral, it emits less CO2 than coal and can act as a bridge in moving towards fully renewable energy systems. And in addition, the court took into account the EU’s tough climate goals—like cutting greenhouse gases by 55% by 2030 and achieving climate neutrality by 2050—supporting the European Commission’s approach.

This decision, from the nuclear industry’s point of view, is pretty much seen as a crucial endorsement. It could potentially encourage private investments in new nuclear plants, a sector that’s historically faced high upfront costs, lengthy development periods, and sometimes uncertain regulatory environments. “Nucleareurope,” which is the Brussels-based trade group for nuclear, welcomed the court’s ruling, viewing it as a positive step towards mobilising the financial resources needed to meet EU climate targets.

That said, the ruling also fuels ongoing divisions among member states and those pushing for climate action. Countries like Austria and Spain remain adamant that sustainable finance labels should exclude technologies with notable environmental or safety concerns. Meanwhile, nations such as Poland, Hungary, Bulgaria, and the Czech Republic support including gas and nuclear as transitional tools, as their energy mixes and levels of readiness differ across the bloc.

This legal decision also comes at a time when there's continued debate over how future EU budgets should be allocated. The European Commission has suggested that member states could direct part of the upcoming €865 billion Budget (for 2028–2034) towards nuclear energy projects. This could be a reflection of the ambitions of pro-nuclear countries to cut down their CO2 emissions. However, opposition from Germany and Austria remains strong, highlighting how hard it is to build consensus around funding nuclear power.

In the end, the court’s ruling confirms that nuclear energy and natural gas will remain classified as sustainable investments under the current EU taxonomy. This underpins their eligibility for green financing and supports the EU’s broader climate strategy. But, as always in these discussions, there’s a tangled web of balancing different national policies, environmental safety, and investment needs, which makes the path to climate neutrality quite complex and contentious in Europe.

  • https://apnews.com/article/26c575d819e15ec686ec7e3e8e8e22fc - The European Union's General Court has upheld the inclusion of nuclear energy and natural gas in the EU's classification system for environmentally sustainable economic activities. This decision, which rejected Austria's legal challenge against the European Commission, allows these energy sources to be labelled as 'green' investments, potentially attracting substantial financial support. The ruling affirms the Commission’s authority to classify certain gas and nuclear activities as transitional tools in the EU’s broader push toward climate neutrality by 2050, acknowledging that member countries have diverse energy needs and starting points. Austria, supported by Luxembourg, argued that such a classification promotes 'greenwashing' and detracts from truly renewable energy sources like wind and solar. Austria, which has no operational nuclear plants, may appeal the decision. The nuclear industry welcomed the ruling, seeing it as an opportunity to stimulate private investment. Critics argue that labelling fossil gas and nuclear as green misleads investors and weakens environmental investment standards. The classification system is crucial for channelling EU-wide sustainable investments.
  • https://www.reuters.com/sustainability/climate-energy/austria-loses-legal-challenge-eus-green-gas-nuclear-rules-2025-09-10/ - Austria has lost a legal challenge against the European Union’s decision to categorise nuclear energy and natural gas as climate-friendly investments. The ruling was issued by the EU’s General Court, which determined that the European Commission acted within its rights when it included these energy sources in the EU’s 2022 sustainability taxonomy. The court stated that, under certain conditions, nuclear and gas activities can aid climate change mitigation. The original measure sparked significant debate among EU countries: while Austria, Spain, and Denmark criticised the inclusion—particularly gas—as undermining climate goals, others like Poland and Bulgaria supported it as a transition tool away from more polluting fuels such as coal. Austria had argued that nuclear energy violated the principle of 'do no significant harm' due to the risks associated with radioactive waste, a sentiment strongly held in a country that has never operated a nuclear power plant.
  • https://www.euronews.com/my-europe/2025/09/10/austrias-push-to-scrap-nuclear-from-taxonomy-snubbed-by-eu-court - Austria’s attempt to prevent the EU categorising nuclear power and natural gas as 'sustainable' for the purposes of EU investment schemes was dismissed by the EU court on Wednesday. Including the two sources of power within the EU taxonomy as sustainable was a 'gradual' measure which would 'allow security of supply', judges found. A traditional anti-nuclear member state, Austria filed a lawsuit against the European Commission in October 2022 but the Luxembourg-based General Court backed the EU executive, arguing that it didn't exceed its powers when including nuclear energy and fossil gas in the sustainable investment scheme. It means certain activities in the nuclear energy and fossil gas sectors may be classified as contributors to climate change mitigation or climate change adaptation. EU taxonomy rules are a sort of green rulebook to guide investors, businesses and governments on which economic activities are environmentally friendly. These rules kicked off in July 2020 aimed at mitigating climate change, pollution and fight greenwashing. 'The Commission was entitled to take the view that nuclear energy generation has near to zero greenhouse gas emissions,' the Court declared, adding that the EU executive took 'sufficient account' of the risks associated with normal operation of nuclear power plants, serious reactor accidents and high-level radioactive waste. With binding climate rules to slash greenhouse gas emissions by 55% by 2030, reach climate neutrality by 2050, and with an impending 2040 climate target currently under discussion, the court ruling also took into account the lack of available sufficient alternatives, such as wind and solar power, at the scale required to address energy needs in a continuous and reliable manner. 'This ruling sends a disastrous signal to the entire EU. If this assessment stands, it destroys a basic principle: where it says green, it is no longer truly green. Those who want green will end up with nuclear power or dirty gas,' Parliamentary leader of the Austrian Greens, Leonore Gewessler, reacted in a note seen by Euronews in which she urged the country’s climate and environmental minister Norbert Totschnig to 'immediately appeal' the judgment. As Austria’s responsible minister in 2022, Gewessler filed the lawsuit against parts of the EU taxonomy claiming that the law would open the door to the greenwashing of climate-damaging and dangerous technologies. 'Nuclear power is dangerous, expensive, and leaves behind highly radioactive waste for hundreds of thousands of years. It is not a solution to the climate crisis – it creates new dangers. Every euro wasted on costly reactors is missing from the expansion of the real solutions: solar, wind, water, and geothermal energy,' Gewessler added.
  • https://www.reuters.com/sustainability/climate-energy/eu-opens-door-funding-nuclear-energy-next-budget-2025-07-17/ - The European Commission has proposed including nuclear energy in its 2028-2034 EU budget, allowing member states to use part of their national share—approximately €865 billion—for nuclear power, specifically the installation of new fission capacity. This marks a significant shift from the current EU budget, which excludes funding for conventional nuclear plants due to ongoing disagreements among member states. Pro-nuclear countries like France and Sweden support funding atomic energy to reduce CO2 emissions, while Germany and Austria remain firmly opposed. Germany swiftly rejected the proposal, citing national sovereignty and taxpayers' interests. Although there have been signs of changing attitudes in countries such as Germany, Denmark, and Italy, EU diplomats doubt there is sufficient support for such funding. The new budget proposal initiates what is expected to be years of complex negotiations, as unanimous approval from all member states is required. The EU has historically been divided over nuclear energy's role in its climate policy, a dispute that has delayed broader energy and climate reforms.
  • https://www.world-nuclear-news.org/articles/nuclear-has-a-place-in-eu-taxonomy-court-rules - The European Union's General Court has dismissed Austria's attempt to annul the European Commission's inclusion of certain gas and nuclear activities in its list of officially approved 'green' investments. In 2020, the EU legislature adopted the Taxonomy Regulation, by which it established a framework to facilitate sustainable investment. That regulation is aimed at channelling finance flows towards sustainable activities with a view to achieving a climate-neutral European Union by 2050. To that end, the regulation lays down the criteria for determining whether an economic activity qualifies as environmentally sustainable for the purposes of establishing the degree to which an investment is environmentally sustainable. The court found that the Commission did not exceed its authority by including nuclear energy and gas. The court endorsed the view that economic activities in the nuclear energy and gas sectors can, under certain conditions, contribute substantially to climate change mitigation and adaptation.
