“Effects of G30” (1) Financial Effect

Two incineration plants were closed down due to a significant reduction in the amount of garbage.

A future cost of 110 billion yen (1 2 billion US$) A future cost of 110 billion yen (1.2 billion US$) for reconstruction was saved.

The 3 billion yen (32million US$) per year operational cost was saved.

(2) Reduction of Environmental Impact

CO2 emissions from treating garbage were reduced significantly

CO2 emissions in FY 2007 were reduced by 840,000 tons when compared to FY 2001. This is equivalent to the CO2 absorbed by 60 million Japanese cedars in one year.Japa ese ceda s o e yea

Consolidated, Environmentally-Friendly Urban Hub Model:

Condensing major city functions into a small number of hubs would lead to a high-density development with efficient land use, thus enabling the maintenance of open space in a more planned manner.

Improved workplace and residence relation, to upgrade and improve lifestyle (ease, comfort & safety).

Mixed-use & diversity of usage to allow exchange of surplus energy between residential area and industrial area, aiming towards mutual benefit and energy efficiency.

Close-Knit (Consolidated) City Structure + close workplace-residence consolidated lifestyle reduces dependency on private cars and in the process makes an energy-efficient city.
