TOKYO -- Big Japanese developers have begun ramping up plans to switch to renewable energy at office buildings, jumping on board the country's emissions-cutting drive while also looking to attract eco-conscious tenants.
Mitsubishi Estate plans to have about 30 buildings in the Marunouchi central business district, including the Shin-Marunouchi Building and Marunouchi Oazo, run completely on renewable power, from sources such as biomass facilities operated by electricity supplier Eneos. The shift will start in April with 18 of these buildings, with the rest making the jump as early as fiscal 2022.
