In order for Japan to achieve its stated goal of becoming carbon neutral by 2050 it will need to restart almost every nuclear reactor it shuttered in the aftermath of the 2011 meltdowns, and then build more. Japan must have 27 of its remaining 36 reactors online by 2030 to hit its obligations under the Paris climate accord, Al Jazeera quotes Masakazu Toyoda, a member of the 24-strong government panel that’s devising new policies as saying. Other estimates put that figure at closer to 30, while so far, only 9 units have been fired back up since a program of restarts began in 2015.
