Tokyo Cap and Trade: Outline 1
Cap-and-trade system for cities
World’s first urban cap-and-trade program
targeting urban buildings
1300 urban facilities consuming large amount of
energy inTokyo including ooffices, commercial
facilities, factories, hospitals etc.
+ Targeting existing buildings
+ Targeting emissions from a building as a whole
Tokyo Cap and Trade: Outline 2
Targeting Gas
Energy related CO2 emissions
+ Focusing on demand side energy consumption
Including scope 2 emissions of electricity consumption, gas
consumption, fuel consumptions
+ Capturing real energy consumptions (emissions)
= building design
Coverage
40% of total CO2 emissions from commercial &
industrial sector in Tokyo
Tokyo Cap and Trade: Outline 3
Requirement: Covered facilities are obliged to reduce CO2 emissions by
an average of 6 or 8% over a 5 year period
Disclose the emissions and reduction plans on the TMG
website
Emission Trading: Excess reductions over obligated amount is tradable
Enable cost benefit solutions for every participant
Offset system to encourage renewables and reduction in
small facilities
TMG Green Building Program 1
Coverage: Newly planned large buildings (over 5,000 sq. Meters)
Requirement:
Submit sustainable design plan with its ratings
Satisfy energy standard of Tokyo
Covering 40% of new buildings
Rating and disclosure system for new buildings to promote sustainable design
TMG Green Building Program 2
Rating: 12 items in 4categories are rated
based on the TMG guideline
Disclosure:
Rated results are disclosed
on the TMG website
Rating and disclosure system for new buildings
Category Items

TMG Green Building Program 3
Green Labeling Program
for Condominiums (2005~)
Labeling programs based on the GBP Energy Efficient Certificate System
for non-residential buildings (2010~)
Incentive planning and zoning
Utilizing the GBP ratings as a prerequisite
Carbon Reduction Reporting for small and medium facilities 1
Target: Small & medium emitters not covered by the Tokyo C&T
Requirement: Reporting annual CO2 emissions and their reduction plan
Disclose on the TMG website
Over 34,000 facilities are reporting including 10,000 volunteers
The results of the first year report:
Tokyo Cap and Trade 1
In total 13% Reduction
from the base-year emissions
Cf. Their obligated reduction; 6 % or 8%
64% of the covered facilities
reduced more than the obligations
The results of the first year report:
Tokyo Cap and Trade 2

Continuity
4. What we learned?
Five misunderstandings for energy efficiency
Key factors for success from policy perspective
Need to break misunderstandings on building energy efficiency
1. We have already done a lot!
2. We know our buildings well, there’s nothing else we can do!
3. It’s costly to retrofit. We can not afford it!
Typical complaints from building owners
Important factors for success from a policy side
Data, Data, Data
To support understanding data
Disclosure, Benchmarking, Feeding back
To support for action Find and disseminate good practices, Require tennants to participate
To create fair & competitive environment
To make the issue the top business managerial decision
