Swiss voters are casting ballots in a referendum led by environmental groups that would require the government to set a precise timetable to end the country’s production and use of nuclear energy.
Polls have suggested a close race.
After the Fukushima nuclear disaster in Japan in 2011, the Swiss federal government decided to transition the country toward renewable energy by 2050. It says nuclear plants should continue to operate as long as they are deemed safe.
The proposal being voted on would close the last of Switzerland’s five nuclear power plants that now generate 40% of the country’s electricity by 2029.
Switzerland regularly holds referendums in its form of direct democracy, which allows voters to set policy.
