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. )

Mechanism of promotion
• Levy 4% of utility cost in each department as TSCP promotion cost• Set TSCP promotion cost based on investment recovery time• In a long run, ensure equity among departments
