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 Rating and disclosure system for new buildings to promote sustainable design

Coverage: Newly planned large buildings (over 5,000 sq. Meters) Covering 40% of new buildings

Requirement: Submit sustainable design plan with its ratings Satisfy energy standard of Tokyo

TMG Green Building Program 2

Rating and disclosure system for new buildings Category

Rating:

Energy

Rated results are disclosed on the TMG website

Heat load resistance of the building envelope

Renewable energy

12 items in 4categories are rated based on the TMG guideline

Disclosure:

Items

Energy efficient building system (equipments) Efficient control systems

Resources Material

Eco-materials Protection of ozone layers

Longer building life expectancy Hydrological cycle

Natural environment Heat-Island effect

Greening (vegetation, landscape, etc.), bio-diversity Atmospheric heat waste

Surface of ground and buildings Wind environment

TMG Green Building Program 3 Labeling programs based on the GBP Green Labeling Program for Condominiums (2005～)

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?

Green Buildings Prodctivity & Confortability

Business Continuity

 Already introduced measures

 Already have action plans  Already have communications

4. What we learned?  Five misunderstandings for energy efficiency  Key factors for success from policy perspective

Need to break misunderstandings on building energy efficiency Typical complaints from building owners 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!

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

Mutual Learning is the Key Sharing knowledge and experiences in depth
