TOKYO - Japan is not considering building new nuclear power plants to help it become carbon-free by 2050, the government’s top spokesman said on Wednesday.

Suga unveiled the 2050 goal after Japan said it aimed to be carbon-free sometime in the second half of the century

For the world’s fifth-biggest emitter, reining in emissions from utilities that contribute about 4/5ths of carbon dioxide output is key to achieving the deadline set by its new prime minister, Yoshihide Suga.

“At this stage we are not considering the construction of additional nuclear power plants,” Chief Cabinet Secretary Katsunobu Kato told a regular news briefing.
