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

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

Carbon Reduction Reporting 2

Benchmarking 22 building-use categories in 7 ratings

3. How it works?

Results of the programs

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

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

Sharing knowledge and experiences in depth

Mutual Learning is the Key
