MM21 District: Leading Business & Tourist district in Japan
About 10% of energy consumption by the business sector in Yokohama
comes from the MM21 district, while it accounts for only 0.4% (186 ha) ofthe whole city area.

Difficulty in GHG Reduction at Household Sector
Difficult to understand each effect on climate
Difficult to contribution on climate change mitigation
Little attractive for climate change mitigation
