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.

3. Outline of Yujiapu Financial district

Location Tianjin Yujiapu financial district in Binhai new area

Project The first low-carbon CBD (Central Business District) development project in this large scale.Financial center in Bonhai Bay area, the center of international trade, the center of information services, the center of international culture and amusement

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

Framework of LCMT FS in Yujiapu

(0) Investigate the detailed information about Yujiapu necessary for FS

4. Construction of the LCMT concept

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

(2) Define the CO2 reduction targets and other concerning indexesfor 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

4

Analyze CO2 reductions and cost increase of measures in each category
