University target (2012) 15% reduction of non-experimental origin from 2006

Bunkyo city’s target (2014 & 2019)8% reduction from 2005

Cap and trade system of Tokyo Metropolitan Government (since April 2010)First compliance period: 2010-2014Target: 8% reduction from recent base years

(office and universities)

Campus GHG target

• TSCP2012 （ 2008-2012 ）　 15% CO2 emission reduction from 2006 level by 2012

– Support of renewal to energy-saving equipment, which　・ Investment recovery time is less than half of its renewal period ・ Achieve big annual CO2 reduction compared with initial cost– Visualization (electricity meter ）– Development of dissemination model by large-scale procurement

• TSCP2030 （ -2030 ）　 50% CO2 emission reduction from 2006 level by 2030

– Plans to be determined by 2012– Introduction of high-efficiency model at the time of renewal of the

equipment's– Introduction of renewable energy （ Solar power, etc. ）
