Outline of Yujiapu financial district- The financial district occupies approximately 4km2 with a total construction area of

9,500,000m2 *4

- Total planned daytime population is 500,000 and nighttime population is 50,000.- Construction is ongoing in some part of precedent development area.- Most of architectural planes within this district are selected by international competition.

Prepare a Low-Carbon Strategy for Yujiapu CBD based on “LCMT Concept”

(1) Develop a comprehensive concept for low carbon town development

(2) Define the CO2 reduction targets and other concerning indexes for evaluating the progress of low carbon

(3) Prepare the categories to make low carbon challenge in urban development

(4) Select and develop CO2 reduction measures in each planning category

Analyze CO2 reductions and cost increase of measures in each category
