  1. University collaboration with local communities toward the formation of low carbon city in Bunkyo City. Keisuke Hanaki University of Tokyo ISCN symposium in Shanghai, 2010

  2. Location of campus 10undergraduate school,15 graduate school, 11 institutes and 18 centers, etc. 1,592,030㎡ Total floor area of UT (Todai Five main campuses: Hongo, Komaba1, Komaba2, Kashiwa, Shirokane) Ibaraki Saitama Kashiwa Tokyo core Tokyo Hongo chiba kanagawa Komaba 1 Komaba2 Shirokane

  3. Size of Todai 7,649 Board, faculty, staff 36,173 members 14,197 undergraduate school 14,327 graduate school 891,000㎡ Total floor area of Five main campus Hongo 148,000㎡ Komaba 1 1,369,000㎡ 119,000㎡ Komaba 2 83,000㎡ Shirokane (86% of total floor area of whole UT) 126,000㎡ Kashiwa

  4. Analysis of current facilities 143,926（ton-CO2/year） Energy source: Electricity 85%, City gas 14%and Heavy oil 1% Hongo 0.10（ton-CO2/ m2） Komaba 1 0.05（ton-CO2/ m2 ） 0.10（ton-CO2/m2） Komaba 2 0.07（ton-CO2/ m2 ） Shirokane 0.19（ton-CO2/ m2 ） Kashiwa 0.09（ton-CO2/ m2 ） • Hongo campus • Total emission: The biggest emitter among the offices in Tokyo • Emission per floor area: Average among the offices in Tokyo

  5. GHG emission from Todai in Tokyo Hongo Shirokane Komaba 2 CO2 emission (ton-CO2/Year) Komaba 1 Share of Todai in CO2 emission from universities located in Tokyo

  6. Characteristics of Bunkyo City • Bunkyo city (ward) is one of 23 cities in Tokyo Metropolitan area • Population: 178 thousands (2005)Daytime population: 336 thousands • Household: 97 thousands (2005) • CO2 emission: 1.15 million t-CO2/year6.46 t/nighttime population-year • CO2 emission breakdown • Household sector: 25% • Office, Commercial and service sector: 52% • Many universities Bunkyo Tokyo 23 cities (ward)

  7. CO2 emissions from large facilities in Bunkyo City (2007) 8.7% of all emission from Bunkyo City

  8. GHG emission reduction target • 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: 2010-2014 • Target: 8% reduction from recent base years(office and universities)

  9. 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 reductionfrom 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.）

  10. GHG Reduction Plan & StrategiesTarget Increase due to new hospital and super computer July 2008 to March reduction: 20134,300ton-CO2/Year Standardyear TSCP2012 Target Reduction of 19,500 ton-CO2/Year necessary after April 2010 Annual CO2 emission (ton-CO2/Year) Expectation Annual CO2 emission in five main campuses

  11. GHG Reduction Plan & StrategiesFinancial incentive • 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 Plan-Do-Check-Action Cycle on TSCP TSCP2012 Master Plan 【Investment recovery time 】 Plan examination Measures execution Each school ･･･four years Effect verification TSCP promotion cost ･･･rest Reflection in plan Additional measures Levy 4% of utility cost Administrative office Department Mechanism of promotion

  12. Collaboration with company - Domestic CDM - • Fluorescent lightings (38,605) were replaced with energy saving type (Hf) • Long payback time (6.9 years even with large-scale procurement) • Lawson (convenience store company) purchases credit from Todai as a CSR activity. Before After ＦＬＲ fluorescent lighting Ｈｆ fluorescent lighting 100Watt 56Watt ×38,605 lights

  13. Collaboration with Local NPO and other local universities • Promotion of pro-environmental behavior • University: Analysis of consciousness based on questionnaire survey • NPO: Practice in primary schools and small action in various meetings/events

  14. Primary school education • Purpose: energy saving behavior at home • Age: 10 or 11

  15. Effect of behavior change of children at home

  16. Kindergarten visit • Age: 5-6 • Participation of studentsfrom local universities

  17. Continuing efforts • Involvements within university • Power of students • Recognition by researchers • Top initiatives • Collaboration with local community • Participation of students • Volunteer basis • academic program basis (local internship) • Collaboration with local companies
