European Union lawmakers voted to allow natural gas and nuclear energy to be labeled as green investments, removing the last major barrier to potentially billions of euros of funding from environmental investors.

Parliament fell short of the 353 votes needed to reject the inclusion of gas and nuclear technology in the EUs so-called Taxonomy, a list of economic activities deemed in line with the blocs transition to climate neutrality. Barring an unlikely objection from member states, it now means the regulation will start at the beginning of next year.

The vote means that new gas plants will be able to tap into a fresh pool of money from environmental, social and governance investors, albeit for a limited time and only when those facilities are replacing coal-fired stations. It will also serve as a boost to Europes struggling nuclear sector, which countries like France have touted as a low-carbon energy source crucial for the replacement of Russian fossil fuels.


The result is a relief for the European Commission, the blocs executive branch, which had first mooted the proposal late last year. The legislation had looked increasingly unpopular after Russias invasion of Ukraine put into question the role of gas as a transition fuel amid soaring prices and the threat of reduced supplies.

The bulk of the conservative European Peoples Party had voted Tuesday to support the inclusion of gas and nuclear after a last-minute plea by Ukraines energy minister, German Galushchenko. In a letter to lawmakers, he said excluding the energy sources from the taxonomy could be particularly challenging for the countrys post-war reconstruction.

Some of the Commissions proposals: 
  • Gas projects replacing coal and emitting no more than 270 grams of CO2 equivalent per kilowatt-hour can get a temporary green label, or if annual emissions dont exceed an average of 550 kilograms per kilowatt-hour over 20 years.
  • Such plants would have to obtain construction permits by 2030, and have plans to switch to renewable or low-carbon gases by end-2035.
  • Nuclear is eligible if new plants that are granted construction permits by 2045 avoid significant harm to the environment and water resources.
  • Funds need to enhance disclosures to investors on nuclear and gas holdings under the taxonomy.

Scientists, environmental activists and even a large part of the investment management industry had criticized gas and nuclear getting a green label on concerns that it could divert investment from renewables and tarnish what the EU had pitched as a gold standard for green finance.

Since the taxonomy eligibility of nuclear energy and natural gas is not only politically, but also scientifically contentious we would have preferred if the Parliament had decided against inclusion of these activities in the taxonomy, said Thomas Richter, chief executive officer of the German Investment Funds Association.

Still, Austria and Luxembourg have signaled that they plan to pursue a legal challenge to the inclusion of the two energy sources in the taxonomy, though its a process that could take years.

Its completely clear that both nuclear energy, and fossil gas have nothing to do with sustainability, Leonore Gewessler, Austrias energy minister, said Wednesday. We will naturally challenge. We have already made preparations and Luxembourg has announced it will join us.
