Carbon-emission and emission-cut measures in CHIYODA-ward
A: emission-cut by increased operation of nuclear powers
B: emission-cut by reinforcement of EE standard for buildings&facilities
C: emission-cut by RE ,area-wide energy system ,off-set and other measures

Area-wide low carbon policy & action program (1)<purpose>1.

Low carbon target can not be achieved by only single measure of EE
for individual buildings.
2. Area-wide cooperative action is expected to work effectively
in order to make the most of renewable energy source.
<Scheme>
1. Following areas are designated as “Low carbon action area” under
the ordinance of CHIYODA ward.
* urban regeneration area designated by law* individual development project area
* existing DHC service area
* AEMS model area
2.

Setting up “Area council” composed of area stakeholders,resource persons and CHIYODA ward.

Area-wide low carbon policy and action plan (2)3. Sturdy and consultation* Sturdy on feasibility of the use of RE focusing on waste-heat andwater-heat (river,sewerage,underground),biomass(waste,wood).
*Sturdy on “off-set projects” if necessary.
(domestic CDM is expected to be in practice)
4.Mapping out “Area-wide low carbon policy and action program”
covering short, medium and long term.
* Development plan of area-wide infrastructure for low carbon energy* Implementation plan of individual RE projects* Implementation plan of off-set projects* Time scheduling and cost-sharing plan
5.Sign for agreement, Setting in “planning documents”.
*planning power could be effectively utilized
6.Setting up “Low carbon fund” contributed by members of area council*Fund money goes to the implementation of “action program”

Role of City Planning toward Low-carbon Society
1.

It’s imperative to take more effective measures for the carbon reductionin the domestic sector and business & commercial sector.

2.

As a first step,
Reinforcement of Energy Efficiency (EE) for buildings and facilities.
* Level-up of the standard of EE*Strengthening of building regulation (2000m2300~500m2)

3.

For meeting post-Kyoto target(medium/long term target),As a next step, “Area-wide carbon-cut measures” are indispensable.

4.

Area-wide measures could be smooｔhly implemented by utilizing“opportunity&site”of City planning and urban development project.

Self-managed Corporate Action Program by business sector

Measures to building&facilities*EE building*EE facilities,electrical appliances*Energy-management system<BEMS,HEMS>

Regulative measures(volume control)
Economic measures(emission-trade, tax)

Self-managed Area Action Program(cooperative program in Action Area)*Improvement of EE for existing DHC systems<plant renewal, system-networking>*Deployment of DHC systems to new development areas.
*Development of area-wide infrastructure for delivering Renewable Energy<waste-heat of incinerator, water-heat of sewerage,river,underground>*Self-planed Carbon-offset<Development of off-site RE><Implementation of Low-carbon development in other areas>< Support of Low-carbon projects under “Domestic CDM scheme>

Making the most of planning tools &consensus-building procedures in planning process
1.

Unified policy & action program of City planning with Climate Change

2.

Grand design of future urban pattern & land use,
urban regeneration,new urban development and transportation system
incorporation of low-carbon program into planning documents

3.

Area-wide planning andArea-wide urban development(or renewal) project.
consensus- building to “Zero,Low-carbon development”

4.

Multi-functioning of roads,parking-lots,parks&open spaces,sewerageas “Energy Infrastructure”

Pilot Projectｓ in Large Cities
1.

Formulation of “Low-carbon program” in “Urban Regeneration Area”
designated by Urban Regeneration Promotion Law.

2.

Implementation of Low-carbon projects in Regeneration Area.
*Development of Thermal Grid by RE(waste heat, water heat)*Development of Thermal-network connecting existing DHCs
*Development of Sustainable transportation system

3.

Incorporation of “Thermal micro- grid” by biomass and solar- system* New development projects in suburban area*compact-town developments around railway stations* Housing-renewal project areas* Shopping-street areas

Pilot Project in Local Cities and Towns
1.

Formulation and Implementation of “Low-carbon cluster development”
toward “Energy-sustainable compact-city”

2.

Energy system in low-carbon cluster development:*wood pellet boiler and solar thermal system*wood pellet (chip) fired cogeneration system

3.

Cluster-development project sites:*Urban regeneration projects in the city center where have been facing
population decrease and de-urbanization.
*Surrounding area of public facilities where could function
as “Cluster(community) energy center”*Mixed-use development based on block-reconfiguration*Supported by “Domestic CDM”(Investment from large-city as off-set)

What should be doneFirst-step:* Formulation of model planning system<Master plan, Area plan, Infrastructure plan>*Development of “Zero-,Low-carbon Model Projects<new dev. project, renewal project><100t saving-model, 500t model, 1000t model>*Study on Low-carbon energy business & investment<cost-effect, end-user’s merits>
Second-step:*Formulation of PPS*Formulation of guidebook on action program for municipalities*Domestic CDM for the promotion of Low carbon projects
Third-step:*Diffusion& Education<symposium, workshop, seminar>
Forth-step:*Implementation of Low carbon planning in municipalities*Implementation of Zero-,Low-carbon projects in urban development
