4. Tokyo Climate Change Strategy
Target
25% Reduction in GHG Emissions
By 2020 from the 2000 level

5. Tokyo Climate Change Strategy
Basic Policy
1 Importance to approach the demand side of energy
As a large energy consumer, Tokyo has a responsibility to reduce
emissions from the demand side of energy
2 Importance to reduce emissions from
urban facilities (buildings)
Promoting measures in the buildings sector is the key to reduce emissions
from urban areas
3 Enable Tokyo to grow in the coming
carbon restrain age
Taking an advantage of the early shift to a low carbon city
to realize sustainable growth of Tokyo

9. T okyo Cap & Trade : Coverage
The urban cap and trade program
to cover commercial sector buildings
including office buildings
Target facilities: 1,300 facilities
Facilities with annual energy consumption of
1,500 kl or more (crude oil equivalent)
Approx. 1000 commercial & institutional buildings
Approx. 300 industrial facilities
Covers approx.40% of
commercial & industrial sectors’ emissions

10. S trict Cap Setting
to Achieve the TMG Target
To achieve the Tokyo’s emission reduction target “By 2020 25%
reduction from 2000”, the necessary reduction in industry &
commercial sector is 17% reduction
Base-year 1st compliance period 2nd compliance period
emissions （ 2010-2014) （ 2015-2019) 2020
About 17 % *
reduction
6 % reduction
5yrs average
* Current estimation.
The Cap for the 2nd compliance period will be fixed
by the end of the 1st compliance period

Tradable allowance:
Reductions exceeding the obligation
Creation of Emission Reduction Registry System:
Reductions exceeding
Creation of a MRV system:
Guidelines on MRV
Requirements of verification by a registered verification
agency

13. Emission Trading: Offset Credits
1. Emission reductions from small and midsize
facilities within the Tokyo area
* Emission reductions through energy-saving measures in smaller
facilities not covered by the TC&T
2. Renewable Energy Certificates
* Solar energy (heat and power), wind energy, etc.
* No limit for offsetting
3. Emission reductions outside the Tokyo area
* Sellers will be assumed to be covered under the
Tokyo Cap-and-Trade Program, and reduction exceeding the
reduction obligation would be counted as offset credit
* Can only buy up to 1/3 of base year emissions
Currently, 307 projects, 220 thousand t-CO2 have filed as offset credits

14. The First Year Report in 2010
 Targeted facilities are subject to submit annual reports
every year
 Total reduction rate from base-year emission: 10%

15. Tokyo Green Building Program
Rating and Disclosure System
To improve environmental
performance of new buildings
Coverage: Newly planed buildings over 5,000 sq. meters
Purpose: To create a real estate market where greener buildings
are valued more
Requirement:
Building owner is required to employ eco-friendly design
and to submit a “Building Environmental Plan” outlining
the building’s environmental performance
Disclosure: Plan with rated result with 3 ratings are displayed on
TMG website
Covers about 40% of new buildings
