More than half of Europeans (52 percent) do not consider natural gas a sustainable source of energy, the World Wildlife Fund (WWF) reports based on a survey of more than 8,000 Europeans in eight countries.

55 percent believe that nuclear energy should not be seen as green energy either.

In the first week of July, the European Parliament will decide whether natural gas and nuclear energy should be regarded as sustainable energy sources. If parliamentarians agree, billions of euros will be diverted from green technologies such as wind and solar energy, WWF warns.

The latter two are seen as sustainable by a large majority of Europeans, according to the survey. 86 percent of the respondents see wind energy as green and no less than 91 percent think that solar energy is.

34 percent of the respondents see natural gas as sustainable. 29 percent think that of nuclear energy. 60% of those polled believe that the European Union should accelerate plans for sustainable energy as a result of the conflict in Ukraine.
