The efforts are a bid to cut 46 per cent of its carbon output from 2013 levels by 2030, while the country has also pledged to be carbon neutral by 2050.
“I would like to promote the maximum adoption of renewable energy, thorough energy conservation and the restart of nuclear power plants with the highest priority on safety,” newly appointed economy, trade and industry minister, Koichi Hagiuda, told his first news conference.
It comes amid a cabinet shuffle in Japan, as its government makes way for new prime minister Fumio Kishida.
The minister, formerly Japan’s education secretary, has kept up the Kishida administration’s climate promises.
Hagiuda also said his department aims to win cabinet approval of a new energy plan before the end of the month – ahead of the UN’s flagship climate conference on November 1.
Though the move to restart its nuclear power industry comes after the country’s decision in April to release more than 1m tonnes of contaminated water from the Fukushima nuclear plant into the sea.
The decision received widespread criticism, with neighbouring China labelling it “extremely irresponsible”.
Just last week the UK set out its own plan of action to bring more nuclear fusion power to the country, in a bid to help decarbonise the energy sector.
The UK is looking to muscling in on a leadership position in the development of fusion energy globally, as the power does not have to rely on wind levels to produce vast amounts of energy in a relatively ‘clean’ way.
