TOKYO -- Japanese telecommunications giant Nippon Telegraph and Telephone is about to drastically transform itself as the global trend of decarbonization accelerates.

As part of its new strategy, NTT has tied up with the Iwate Prefecture city of Miyako, whose energy networks were cut off in 2011 as a result of the devastating earthquake and tsunami. Learning from this bitter experience, the city now uses renewable energy sources to meet about 30% of its electricity needs. It plans to raise the proportion to 100% by 2050 through its tie-up with NTT.
