Framework of LCMT FS in Yujiapu 4. Construction of the LCMT concept Framework of LCMT FS in Yujiapu Prepare a Low-Carbon Strategy for Yujiapu CBD based on “LCMT Concept” (0) Investigate the detailed information about Yujiapu necessary for FS (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 Report Preparation

[ Aiming at real reduction of approximately 50% ] 4. Construction of the LCMT concept (1) Main target < CO2 reduction target > [ Aiming at real reduction of approximately 50% ] 　In 2020 (mid-term) real reduction of approximately 30% (which is over 50% CO2/GDP) 　In 2030 (long-term) real reduction of approximately 50% 1) Standard type buildings without low carbonized 2） GDP growth in 2011 and 2012 in China are predicted 9.6% and 9.5% by IMF analysis. In this CO2 target study, the GDP growth by 2020 is set as 5% that is around ½ of the actual growth with consideration of uncertainty of prediction. 3) Mitigation effects by area energy, renewal energy and untapped energy have been counted into the result of CO2 reduction in Buildings １１ t-CO2/a BAU (Business as Usual) 1) 30% reduction (Transportation) 50% reduction (Transportation) ( 30% ) (Transportation) ( 50% ) (Building) (Building) (Building) ( 30% ) ( 50% ) （50% CO2/GDP2)） in 2010 （Present） in 2020 （mid-term） in 2030 （long-term）
