• Start year: 2010
• Type: Regulation
• Status: In operation

This program encourages small and medium-sized facilities to report their CO2 emissions and the status of their global warming countermeasures
- Target facilities:
Small and medium-sized facilities or offices on business premises in Tokyo with an annual energy (fuel, heat and electricity) usage of less than 1,500 kiloliters in crude oil equivalent
- Reports submitted:
Approximately 2,200 business operators submitted reports for over 34,000 facilities in fiscal 2015.
- Submission types:
1) Mandatory report submission and information disclosure for business operators with multiple small or medium-sized facilities in Tokyo if their combined total annual energy usage is 3,000 kiloliters or more in crude oil equivalent
2) Voluntary submission for other facilities
Main features:
1) Business operators report each facility’s CO2 emissions and the status of specific measures implemented against climate change in the previous year.
2) TMG discloses the information from each facility’s report. It also formulates Low Carbon Benchmarks (self-rated index) using the data in the reports.

Start year: 2010
Type: Policy/Strategies/Action Plans
Status:
World’s first urban cap-and-trade program in terms of covering office buildings
Target: Facilities with large GHG emissions (the consumption of fuel, heat and electric power exceeds 1,500KL per year in crude oil equivalent)
Covered gas: CO2 from energy use
Implementation Period:
The first compliance period (2010-2014)
The second compliance period (2015-2019)
Mandatory Reduction:
Base-year emissions x mandatory reduction rate x 5 (years)
Base-year emissions is the average of any three consecutive years between 2002 and 2007)
Compliance factor: 17% for office buildings, and 15% for factories (The 2nd compliance period)
Ways to meet obligations:
1) On-site energy saving efforts (ex. replacing old equipments with more energy efficient ones).
2) Emission Trading (to buy the following through the trading)
Excess Reduction
Small and midsize facility credits
Renewable energy credits
Outside Tokyo credit (emission reduction from outside of Tokyo)
Saitama Credits
Penalties: In case of failing to fulfill the obligation, the entity is required to reduce 130% of the shortfall, and there will be penalties for violation of the order.

The program aims to promote reductions in the environmental loads of urban buildings including offices and apartments by evaluating building owners’ environmentally-friendly efforts for their buildings and creating a market that highly values buildings with great environmental performance.
- Target buildings: Newly constructed or expanded large buildings with a total floor space of over 5,000 square meters (10,000 square meters from 2002 to 2010)
- Assessed items:
1) Efficient use of energy (reduction of heat loads, adoption of renewable energy, installation of energy-efficient systems, etc.)
2) Appropriate use of resources (use of eco-materials, protection of the ozone layer, global warming prevention, extension of life period, etc.)
3) Environmental conservation (hydrologic cycle, greening)
4) Mitigation of heat island phenomenon (measures against human-derived emissions, covering of building and site surfaces, consideration of wind environment, etc.)
- Evaluation and Announcement: Evaluation results are rated on a one-to-three scale and publicly announced.
