Note) Figures in parenthesis represent estimated values when we assume the CO2 concentration becomes double. In case
the concentration of greenhouse effect gas such as CO2 increases, the energy flow in the dotted line becomes
larger. This causes the rise of temperature. The global temperature is said to fall to as low as -19℃ if no carbon
dioxide or no steam should be contained in the atmosphere.

Note) This chart is prepared from the data of CO2 concentration level of the past millennium based on the ice sheet core
records at the D47, D57, Siple Station and the South Pole, and the CO2 level since 1958 that are measured at
Mauna Loa Observatory in Hawaii. Ice sheet cores were all collected on the Antarctic Continent. The smooth
curve is a 100-year running average. The sharp rise of the CO2 level since the outset of the Industrial Revolution
is evident, going along with the increase of CO2 emissions originating from the use of fossil fuels (See the
enlarged chart since fiscal 1850).

2.2 International efforts to counter global warming
In this chapter we will focus on the two mechanisms that are dealing with global warming issues:
The Intergovernmental Panel on Climate Change (IPCC) is the mechanism that accumulates
scientific knowledge on global warming while debates on the international countermeasures have been
made in the COPs (Conference of the Parties) of United Nations Framework Convention on
Climate Change (UNFCCC). These two mechanisms are complementing each other.
Increase of Atmospheric CO2 Rise of Sea Level Rise of Average World Temperature
★ 265 - 285 ppm before the ★ 10 - 20 cm rise in 20 ★ 0.6±0.2 ℃ rise after 1861
Industrial Revolution (1750 - century
1800) ★ Estimated rise of 1.4 - 5.8 ℃
★ 365 ppm in 1996 ★ Estimated 9 - 88 cm rise between 1990 – 2100
★ 540-970 ppm estimated by the between 1990 - 2100
end of 2100

Kyoto Mechanism
Emission Trading Parties in Annex I may participate in the Emission Trading in order to achieve their
(ET) commitments.
Joint Implementation For the purpose of meeting its commitments, Parties in Annex I may transfer to or
(JI) acquire from, emission reduction units, any other parties in Annex I .
Clean Development The purpose of CDM mechanism is to assist Parties not included in Annex I in
Mechanism achieving sustainable development and to contribute to the Protocol, while Parties
(CDM) in Annex I may use the certified emission reductions accruing from such projects.
16
Enforcement and Effect
Enforcement The Convention shall become effective 90 days after 55 or more parties to the UNFCCC,
incorporating Annex I parties of which total CO2 emission in 1990 is 55% or more of total
CO2 emissions of all Annex I parties, ratify the Protocol.
Effect When no Protocol exists, the global CO2 emission in 2010 will increase by 24% compared
with 1990.
When the Protocol is enforced in 2000, the global CO2 emission in 2010 will reduce by
5.2% compared with 1990.

4) COP8 results and progresses
The COP8 was held in New Delhi, India on Oct. 23 - Nov. 1, 2002.
Results The Delhi Ministerial Declaration on Climate Change and Sustainable Development
adopted at COP8.
1) Strong encouragement of the Protocol ratification to Parties that have not yet.
2) Recognition with the concern of the findings of the IPCC Third Assessment
Report (TAR) which confirms the necessity of significant cuts in global emissions for the
ultimate objective of the Convention.
3) Note to current mitigation actions by both Annex I and non-Annex I countries and
emphasis on mitigation of GHG emissions to combat climate change as continuing high
priority under the provisions of the Convention.
4) Promotion of informal exchange of information on actions relating to mitigation and
adaptation among Parties for more effective and appropriate responses to climate change.
5) Take urgent actions at all levels to substantially increase the global share of renewable
energy sources.
Progresses Issues suspended in the COP7 were discussed and agreed.
1) Activity report from CDM Executive Board .
2) Report and assessment based on the Protocol .
3) Report from each parties

6) COP10 results and progresses
The COP10 was held in Buenos Aires, Argentina on 6-17 December 2004
Results The conference marked the 10th anniversary of the entry into force of the Framework
Convention on Climate Change, which served as a central theme for the meeting.
In addition to the accomplishments of the past ten years and future challenges, discussions
at COP 10 highlighted a range of climate-related issues including the impacts of climate
change and adaptation measures, mitigation policies and their impacts, and technology.
Progresses It was reconfirmed at the conference to be very important that all the countries keep on
cooperating for realizing more effectual measures from now on as well as aiming at the
further advance under the treaty and the Kyoto Protocol.
1) Each Annex I party welcomed the protocol effectuation on 16 February 2006 as the
important first step in promotion of international countermeasures against global
warming. It was identified that the intention of further efforts of each country to have
their respective targets for emission reduction achieved certainly must be sustained.
2) Based on the working plan that studies for the post Kyoto Protocol after 2013 would
start by the end of 2005, It determined to begin operations through information
exchange towards future activities in mid and long-term under participation of all
countries.
Next step The COP 11 will be held in Montreal, Canada from 28 November to 9 December 2005.

2.3 Kyoto Protocol coming into effect
The requirements for the Kyoto Protocol coming into effect included that (1) not less than 55 parties to
the convention ratify the protocol, and (2) parties included in Annex I which accounted in total for at least
55% of the total CO2 emissions in 1990 of the parties included in Annex I ratify the protocol (Figure below).
The requirement (1) was met before some time, and the requirement (2) was met by the ratification of
Russia in November 2004, and thus the Kyoto Protocol came into effect on February 16, 2005.
Consequently, Japan is obliged to reduce the volume of greenhouse gas emissions by 6% from the standard
year level during the first commitment period from 2008 to 2012.
With regard to the commitment of the next period starting in 2013, the protocol stipulates that
international examination begin by the end of 2005. At the COP10 held in Buenos Aires, Argentina in
December 2004, the holding of a seminar for governmental experts was agreed, which will serve as the
foothold of discussion concerning the framework after 2013.

2.4 G8 Summit
The 31st Summit (meeting of leaders of major countries) was held in Gleneagles, Scotland, the United
Kingdom from July 6 to 8, 2005.
By the initiative of Prime Minister Blair, the chair, Africa and climate change were taken up as main
agenda items of the Summit. Japan developed its argument from its original position for the Africa
question, based on its successful experiences of economic development cooperation with Asia, and for the
climate change question, based on its experiences of overcoming pollution problems during the period of
high economic growth and of achieving energy conservation and higher energy efficiency triggered by the
oil crises.
On the issue of the global environment, the Gleneagles Plan of Action involving energy conservation,
clean energy use and other specific actions was agreed upon as well as an agreement to begin a dialogue
between the G8 nations and other countries with significant energy needs (the outcomes are to be reported
to the 2008 Summit in Japan). During the discussions with the leaders of emerging economy countries,
the G8 members asked that these countries shoulder greater responsibility in tackling climate change and
other problems. Japan emphasized the importance of compatibility between environment protection and
economic development, use of technology for that purpose, promotion of the 3Rs (Reduce, Reuse and
Recycle) and the spirit of mottainai (the spirit of virtue of thrift), and increasing efforts to curtail illegal
logging, etc.

2.6 Japan’s policy to deal with global warming
The Guideline presents a broad picture of measures to realize Japan's targets set in the Kyoto protocol
(6% reduction in relation to the 1990 level) and is made up of more than 100 measures and action plans.
What needs to be stressed here is that the Guideline sets a reduction goal for each green house effect
gas respectively. For instance, in terms of the CO2 originating from the use of fossil fuels, the emission
level should be reduced to exactly the same level as that of 1990. And the emission level of CO2 from
non-fossil fuels (e.g. waste incineration), methane and dinitrogen monoxide should be reduced by 0.5% in
relation to the 1990 level. In terms of CFCs substitute, the emission level should be curtailed to the 1%
increase compared with the base year (1995).

4. Energy Conservation Policy in Japan
Although the oil crisis revealed Japan’s fragile supply- demand structure of energy, the
government took advantage of it as a precious lesson and has since been making full efforts to build a
robust supply-demand structure.
Specifically, on the supply level, the diversification of energy sources has been pushed forward
with by switching to alternative energies such as natural gas or nuclear power. On the demand level,
on the other hand, the industrial sector is playing a central role in terms of energy conservation.
As the result of those tireless efforts, the dependence on oil has declined to 52%, which enables
Japan to realize an energy-conservation-oriented society while staying in an economic power at the
same time. And in terms of energy consumption per GDP, our country has been successful in curbing
increasing the consumption, even compared with that of other major developed nations.
In the meantime, the member nations reached an agreement with the target that required
developed nation to cut their GHG emissions at the 3rd Session of the Conference of the Parties
(COP3) in Kyoto 1997. Therefore, in order to reach the goal and conserve the environment on a global
level, further efforts of energy conservation have since been perceived.
More than 90 % of GHG consists of carbon dioxide and approximately 90% of carbon dioxide is
emitted from combusting fossil fuels. That means nearly 80 % of GHG emissions originates from
energy use. For that reason potent and effective energy policies are thought to be the key player in
resolving environmental problems.
In order to achieve the goal of 6% GHG emission reduction set by the Kyoto protocol, the
Japanese government decided to design measures covering the both supply and demand of energy. In
terms of the demand level, for example, it will urge the industrial, the commercial and residential and
the transportation sector to promote more energy conservation, though considerable efforts have
already been taken since the oil crisis. If these measures are put into place, an aggregate of 56 million
kL energy is estimated to be saved in the year of 2010, which is almost equivalent to the annual energy
consumption in all of the households in Japan. This tells us how ambitious the goal of the energy
conservation measures will be.
However, the energy consumption in the commercial sector and the transportation sector has kept
rising partly due to the changing the lifestyles of the Japanese people. Based on this recent trend, the
Advisory Committee for Energy put forward additional measures aimed at the promotion of energy
conservation in the commercial sector and the transportation sector in 2001.
32
(2) Promotion of energy conservation measures
1) Introduction and promotion of energy conservation equipment and systems
For promoting energy conservation equipment, investment in industry and commerce, loan
programs and tax reduction have been established (low interest loans by the Japan Development
Bank and Smaller Business Finance Corporation and a tax system for promoting investment to
reform energy supply and demand structure) by the Energy Conservation Assistance Law.
33
(3) Promotion of international energy conservation measures
Under the policy and support of the Japanese Government, ECCJ has been conducting energy
conservation training programs for developing countries mainly in the Asian region for the
purpose of promoting energy efficiency and conservation of those countries as well as
enhancing the stable supply of energy of Japan. The programs include lectures, practical
trainings at trial plants, factory tours, etc. aiming at transferring Japanese successful
experiences and information (energy conservation policy, energy management, highly
energy-efficient technology, etc.) for energy efficiency and conservation to those countries
which could serve as useful reference for their planning/implementation/spread of energy
efficiency and conservation. .
34
4.2 The Basic Energy Plan
The Agency for Natural Resources and Energy (ANRE) reported the Basic Energy Plan to the
Diet in October, 2003. This plan defines the next 10-year direction of measures on the demand and
supply based on the three principles of the Fundamental Law on Energy Policy Measures. Here are the
details of the three principles.
The supply-demand problem of electricity in the Kanto area should be considered, and reliability
and stability of domestic supply should be secured. And securing energy is a prerequisite for the stable
energy supply. The government and business owners should make full efforts to secure the stable
supply.
35
4.3 Law concerning the Rational Use of Energy
(1) Objective
This law aims to contribute to the sound development of the national economy through
implementing necessary measures for the rational use of energy in factories, buildings, and machinery
and equipment, and other necessary measures to comprehensively promote the rational use of energy,
while it seeks to ensure the effective utilization of fuel resources that would meet the economic and
social environment of energy at home and abroad.
This is to comprehensively promote the rational use of energy through the systematic formulation
and the public announcement of the basic matters pertaining to the measures to promote the rational
energy utilization.
This is to show a guideline of the individual and concrete measures about the basic matters stated
in the basic policy and to guide business operator to judge and conduct appropriate and effective
36
implementation of the rational energy utilization in Factory. (The revised criteria was announced on
10 January, 2003.)
Type 1 Designated Energy Management Factories shall appoint an energy manager to monitor the
work related to the rational energy utilization, prepare and submit a mid-to-long term plan, and report
the status of their energy utilization to the competent minister every year.
However, the buildings in the category of Type 1 Designated Energy Management Factories may
appoint an energy management officer, instead of an energy manager, who has completed a designated
training course that were conventionally conducted in the past. In those buildings, an energy
management officer is conducting day-to-day energy management, but they shall have a participation
of an energy manager , only when preparing a mid-to-long term plan.
<Recommendation>
If Type 2 Designated Energy Management Factory is judged not to comply with the evaluation
criteria for energy rationalization, the competent minister may submit a recommendation to the
operators and request them to take necessary steps for the rational use of energy.
37
5) Category of designated energy management factory
* Submission of medium- to- long- term plan * Submission of medium- to- long- term plan
Regulatory obligations
* Periodical report
38
7) Certified Energy Manager System
In Japan, factories belonging to any of the five designated industries with a total of fuel
and electricity consumption of at least 3000 kL of crude equivalent are designated as Type 1
designated energy management factories under the Law concerning Rational Use of Energy,
and are subject to the obligation to appoint one or more energy managers according to the
level of their energy consumption. Such energy managers must be selected from the holders of
a license of qualified person for energy management.
A license of qualified person for energy management is awarded to any person who has
passed an examination for qualified person for energy management, or who has been authorized by
the Minister for Economy, Trade and Industry upon completing a qualification course of qualified
person for energy management. The process works in the following manner:
a) Category

3) Instructions for specified buildings
Furthermore, if the Minister of Land, Infrastructure and Transport deems that any building (not
for dwelling) of 2,000 m2 or more in total floor area is notably insufficient in the measures taken for
rationalization of energy use in terms of the standards to be referred to, he can give necessary
instructions to the buildings owner on the matters concerning design and construction work, and if the
building owner does not comply, the minister can announce to that effect.
1) Obligations of manufacturers
Those who produce or import energy consuming equipment shall, with the basic policies in mind,
ensure the rationalization of energy consumption concerning the equipment by improving the energy
consumption efficiency of the equipment which they produce or import. Concerning automobiles and
other equipment as specified in the Government Ordinance, the Minister of Economy, Trade and
Industry (and also the Minister of Land, Infrastructure and Transport for automobiles) shall establish
and announce standards for energy consumption efficiency improvement which manufacturers should
refer to in making decisions. Further, the Minister of Economy, Trade and Industry (and also the
Ministry of Land, Infrastructure and Transport for automobiles) may give necessary recommendations
to manufacturers and importers where he considers a considerable improvement is needed in the
energy consumption efficiency of their specific products in view of the standards which they should
refer to in making decisions, provided that the production or import volume for such products exceed a
certain level (for example, more than 2,000 automobiles per year, or more than 500 air conditioners
per year).
The target value of the standard is set up on the basis of the product having the highest energy
efficiency of all the products of the same group sold on the market. (“Top Runner Program”)

41
2) Labeling
Equipment described above shall be marked to show its energy consumption efficiency so that
general consumers can selectively purchase equipment of high energy consumption efficiency based
on the marked correct information of the energy consumption efficiency. The Minister of Economy,
Trade and Industry (and also the Minister of Land, Infrastructure and Transport for automobiles) shall
establish the labeling procedures to be followed by manufacturers etc. concerning energy consumption
efficiency, labeling method, and other matters to be observed in labeling for each item of specified
equipment, and shall issue a notification of them.
Furthermore, if the minister(s) deem(s) that the labeling does not conform to the notification, he
(they) can give a recommendation to the manufacturer, etc., and if the manufacturer, etc. does not
comply, the minister(s) can announce to that effect and give an order to take an action conforming to
the recommendation.

4.7 Top Runner Program
(1) Background
In order to diffuse appliances and vehicles that are highly energy efficient, the revised Energy
Conservation Law makes it obligatory for manufacturers and importers to ensure their products to meet
energy-saving target standards.
The Japanese government launched the Top Runner Program based on the amended Law in 1999, under
which the standards are set based on the efficiency level of the most efficient product commercially available
in a given category. For each manufacturer and importer, the weighted average efficiency of all units
shipped within the same category must meet the standards for that category by the target year decided for
each category.
6) Measurement Method:
The measurement method primarily uses JIS (Japan Industrial Standards).
65
7) Indications:
Responsibility is assigned to indicate the energy consumption efficiency of the device in catalogs, on the
device itself, etc.
66
(5) Merits of Purchasing Top Runner Machinery and Equipment
Prices of Top Runner machinery and equipment are generally higher compared with conventional popular
machinery and equipment due to the latest energy conservation technological features. To encourage
purchases of these machinery and equipment that appear expensive at first glance, to raise consumer
awareness of concept of overall costs, which are acquired by adding running costs (annual costs of electricity
or fuel) to the purchase price is necessary. One example is shown below.
[Air Conditioners]
Comparison of Overall Costs over the Annual Operational Costs of an Energy Efficient Model and a
Popular Model (Cooling Capacity 2.8kW)
Overall Cost
Overall cost savings over a
13-year period for an energy
¥600,000 efficient air conditioner amount
to approximately 204,000 yen.
¥500,000
Comparison:
Comparing air conditioners that energy conservation standard achievement percentage of 55% ( )
and 122% ( ), the difference in the volume of electricity consumed is 918kWh per year after
subtracting 905kWh per year from 1,823kWh per year. If a consumer selects the more energy-efficient air
conditioner model, he will save approximately 20,200 yen on his electric bill over a one-year period.
*To calculate electricity consumption volume, periodic electricity consumption volume (as of end of
October 2003) specified in manufacturer’s catalogue was used.
*Purchase price derived from July 2003 aggregate sales data.
*Air conditioners are used for an average of 12.8 years according to a September 2003 cabinet office
consumer operation survey.
Weighted average energy efficiency = the sum of {(the number of units shipped domestically for each product name and
type) × (energy consumption efficiency per unit)} ÷ the total number of units shipped domestically.
To confirm display implementation, product catalogues, as the primary source for displays, are periodically and
continuously collected. For displays on products themselves, submission of name plates, etc. or retail store surveys are
conducted to confirm the implementation.
67
(7) Measures to be taken in case the Target Values are not Achieved
If the results obtained from the energy efficiency surveys mentioned in the previous paragraph appear to be
remarkably low compared to judgment standards and a need to make suitable improvements in energy efficiency is
recognized at the time, the Minister of Economy, Trade and Industry (in cases involving cars, the Minister of Economy,
Trade and Industry and the Minister of Land, Infrastructure and Transportation) offer recommendations to the
manufacturer in question as required. Further, if this advice is not followed, the recommendations are made public and
the manufacturer may be ordered to follow the recommendations.
Manufacturers subject to these recommendations and advice should be limited to those whose improvements in
manufacturing and imports of equipment are considered to have a substantial impact on energy consumption in Japan.
Also, targets should be limited to manufacturers whose organizational capacity is economically and financially firm
enough, that is, limited to manufacturers for which there will be no problems regarding social appropriateness. For each
machinery or equipment product covered by the Top Runner Standard, a cutback in shipping volume will be set
according to production and import volume, as stipulated by government decree.
Moreover, if, there are categories that partially fail to achieve goals among the many items, it will not be
appropriate to advise the manufacturer immediately. Instead, reasons why goals were not achieved, other companies’
achievement records in the same field, achievement records in other categories of the company in question, and
percentages of categories that have not achieved target standards in overall categories, and other factors will be
comprehensively evaluated.
These measures are implemented for manufacturers that do not adhere to display rules. For displays, cutbacks
based on manufacturers’ production and import volume are not applied and all companies are subject to these measures
in spite of small volume in production and import.
(8) Evaluation Criteria for Machinery and Appliances under Top Runner Program
The evaluation criteria, etc. for manufacturers, etc. regarding improvement of the performance of
“Designated Machineries” pursuant to the provision in Paragraph 1 of Article 18 of the Law Concerning the
Rational Use of Energy (Law No.49 of 1979) are defined and notified by the category of machinery and
appliance.
The details of the evaluation criteria for machinery and equipment are shown in the web-site of ECCJ.

(2) Energy conservation measures in the industrial sector
Since the oil crisis, Japan’s industrial sector has been playing a central role in the efficient use
of energy. Thanks to its efforts, the sector has successfully maintained almost the same energy
consumption level as in the oil crisis in spite of the growing output. Nonetheless, it is also true that
the sector accounts for nearly 40 % of the total energy demand in Japan.
Despite those proactive efforts, there was a growing awareness that more measures were
necessary in order to take more effective actions on global environmental issues. In June 1997, Japan
Business Federation (Keidanren) announced “the Keidanren Environmental Voluntary Action Plan“,
aiming to promote the efficient use of energy on a voluntary basis.
On the policy level, the Law Concerning the Rational Use of Energy (Energy Conservation
Law) was revised in order to reinforce the sector’s voluntary energy management. The revision of
2002 expanded the range of “the Type 1 Designated Energy Management Factory” designation,
which had been limited to five industries such as the manufacturing industry, to all industries. Also
through the revision business operators became necessary to submit periodic reports, who own
factories classified as “Type 2 Designated Energy Management Factory”. The revised law came into
force on April 1, 2003.
Moreover, in unison with the revision of the Energy Conservation Law, new criteria to assess
energy use of factories and business offices were enforced on April 1, 2003, which were to control
inefficient electric power facilities, to promote the implementation of the cogeneration system, which
is highly energy efficient and to make good use of ESCO companies.
In addition, there are also financial incentives, such as low interest loan programs, to boost
investment in developing energy saving products and technologies under the law concerning energy
conservation and recycling assistance, and tax breaks under the tax measures to promote the
investment in the restructuring of energy supply-demand.

c) Dissemination and promotion of energy conservation technology (Spill-Over)
i) What is Spill-Over?
As energy conservation is an important policy for Japan, the energy conservation
technology strategy was formulated in June, 2002 by the Japanese government, the
Agency for Natural Resources and Energy. This strategy stressed the importance of
promoting “spill-over,” to actively spread existing energy conservation technologies to meet
technological needs across various sectors and fields.
The technical term “spill-over” is originally used to indicate the overflow of water, but
now used in various specialized fields. In the telecommunications sector it indicates a
condition in which information communicated by electric waves is leaked; in chemistry it
indicates a condition in which chemical species move on the surface of a catalytic agent,
promoting a reaction; and in economics it indicates a condition in which public investment
has secondary effects. In the field of energy conservation technology, “spill-over” indicates
a condition in which cross-sectional/basic technology has impacts on other fields and
categories, where further development and improvement will generate better energy
conservation technology. This energy technology again has impacts on other fields,
thereby reaching full growth in a cyclical way.
Applying an excellent energy conservation technology into other fields and categories
and expanding its utilization has advantages in that: It does not require duplicated
investment in development costs; it requires shorter development duration; and it has
quick effects. Highly effective energy conservation technologies are already in place.
Spilling over the many excellent technical elements and energy conservation methods of
these technologies will immediately contribute to the promotion of energy conservation.

3. Use of surplus energy, or effective use of energy that has been left unused
4. Introduction of cogeneration, improvement of operation methods, raising utilization
rate
5. Remodeling equipment into or replacing one with high-efficiency equipment
6. Utilization of energy conservation methods introduced by the Energy Service Company
(ESCO) projects
7. Reduction of the consumption of the fixed consumption of energy
8. Effective use of heat, and mutual effective use of heat and materials
9. Energy conservation measures for water
iii) Reduction of the fixed consumption of energy, which is highly needed from the demand
side
92
Methods of reducing the fixed consumption of energy introduced by excellent cases
Among the energy conservation measures in the industry sector, technology highly required
by the demand side is reduction of the fixed consumption of energy that is not in proportion
to production by converting it to a variable energy, which is an energy required in proportion
to the production.
Generally, points for reducing of the fixed consumption of energy are rationalization of a
utility energy supply system, optimization of excess demand, and reduction of consumption
of a standby power requirement.
1. Method 1: Reduction of the fixed consumption of energy by raising production efficiency and
reducing production duration.
1) Cut-down of processing steps by partial integration of production steps
2) Cut-down of duration by paralleling the processes that can directly influence production
efficiency
3) Cut-down of duration by rationalization of preliminary treatment, preliminary processing,
preheating, etc., in production processes
4) Cut-down of duration by rationalization of post treatment, energy recovery, etc. in
production processes
5) Cut-down or omission of post treatment duration by improvement of production technology
(high precision processing and high quality processing)
6) Cut-down of heating/melting duration by improvement and rationalization of energy
consumption rate
7) Cut-down of duration by raising production efficiency through raising production
technology by basic technology
8) Cut-down of waste time to the utmost limit, including cutting standby time in production
processes
2. Method 2: Conversion the consumption of the fixed consumption of energy to the variable
energy
1) Replacing hydraulic actuator system with electric actuator system
2) Replacing pneumatic actuator system with electric actuator system
3) Lowering the set pressure for pneumatic line, and converting the fixed consumption of
energy to the variable energy by using booster pump and buffer tank
4) Lowering temperature level of the retention furnace, and adopting induction heating at
pouring gate and additional heating by DC torch
5) In the heating process, converting the fixed consumption of energy to the variable energy
by adopting infrared heating, laser heating, and pulse combustion burner introducing
6) Reduction of heating and cooling sources by applying recovered heat in before and after
heating/cooling processes in the same production line to preheating and pre-cooling process
7) Diligently setting control values before rebooting in more detail by stopping equipment to
be at standby time by the minute and second
3. Method 3: Reduction of production space and minimization of the fixed consumption of energy
amount
1) Level down of clean room, etc., and raising the cleanliness of each appliance, chamber, and
container
2) Introduction of zone or spot air-conditioning by dividing air-conditioning area
3) Dividing into smaller lighting areas for the purpose of adaptive control of lighting for each
area, and adopting localized lighting and natural light
4) Distributed allocation and adaptive control for boilers, compressors, transformers, power
factor improvement equipment, etc.
5) Reduction of energy for lighting/air-conditioning by adopting Just In Time (JIT) production
system and dividing spaces for assembly process and parts stockyard into smaller areas
4. Method 4: Rationalization and lowering loss of appliances related to the fixed consumption of
energy
1) Adoption of higher efficiency appliances for lighting, air-conditioning, ventilation, water
supply, and other appliances that consume the constant amount of energy
2) Rationalization of fluid pump, blower, etc., by introducing inverter control system
3) Reduction of energy for lighting, ventilation, air-conditioning by mitigating work
environment conditions under unmanned operation
4) Lowering losses by cascade connection of different types of pumps
5) Reduction of waste power by reducing potential risk of steam leakage, compressed air
leakage, water leakage, etc.
6) Reduction of holding energy by improvement of adiathermancy of furnace wall, etc.
93
5. Other methods :
1) Utilization of recovered energy with a total enthalpy heat exchanger, etc., from sensible
heat of products in batch processing system for the energy constantly required
2) Reduction of pumping energy by rationalizing pressure utilization in decompression and
compression chambers in the same production line
3) Converting exhaust heat/coolant in production process to the fixed consumption of energy
by using absorption type refrigerator
4) Reduction of the fixed consumption of energy amount by utilization of internally generated
exhaust heat in clean rooms, etc., for drying
5) Reduction of number of appliances consuming the fixed consumption of energy amount by
time-sharing
For example, hydrogen, which accounts for 55% of the gas generated in coke ovens of
steel plants, can be supplied to oil refineries, where the hydrogen is refined and used for
desulfurization, if the oil refinery is close to the steel plant. It is expected that adoption of
iron carbide as a raw material used in electric furnaces will not only compensate the
electricity required, but also allow surplus electricity to be sold and hydrogen to be supplied
to neighboring plants and communities.

e) Dissemination of high-efficiency industrial furnaces and high-efficiency boilers
combustion combustion)
*1
This project, which is called “development of high-efficiency industrial furnaces, etc.,” consists of three sub-projects:
“combustion control foundation technology,” “development of high-efficiency industrial furnaces,” and “high-efficiency
boilers.” These projects were carried out for seven years from FY1993 to FY1999 as entrusted business by the New
Energy and Industrial Technology Development Organization (NEDO).
*2
The “Field test project on high-efficiency industrial furnace introduction” of NEDO was carried out for three years from
FY1998 to FY2000, receiving a governmental subsidy for one-third of the cost.
95
field test, which targeted 167 industrial furnaces, confirmed an energy conservation effect
corresponding to reduction of 160,000 kL of crude oil equivalent through achieving a 30%
or higher energy conservation rate and 50% or higher NOx reduction. Introduction and
dissemination of high-efficiency industrial furnaces is carried out as a project for
supporting business entities making efforts to rationalize energy use in the New Energy
and Industrial Technology Development Organization (NEDO). The great difficulty in
introduction and popularization of the high-efficiency industrial furnaces is that the
amount of facility investment is not comparable to the advantages of energy conservation
efforts.
High-temperature air combustion technology, which is extremely effective in reducing
CO2 and NOx, is distinctive of Japan and can be regarded as an innovative combustion
technology that plays a leading role in carrying out effective energy use and global
warming prevention measures for the world. Currently, development research is being
conducted in order to practically apply this technology to non-industrial combustion and
heating facilities that consume a large amount of energy.
The efficiency of existing industrial boilers is rather high, achieving 86%-90% (at the
low calorific value of the fuel). The boilers’ efficiency rate of energy use has also reached a
high level among heat application facilities. However, its energy consumption accounted
for a large portion in the industrial sector. The project to develop high-efficiency boilers
started in order to develop high-efficiency boilers that would contribute to reduction of
exhaust combustion gas such as CO2 and NOx, energy conservation, and environment
conservation from perspective of global warming prevention.
Among the future challenges are reduction of oxygen production cost (PSA oxygen
supply device, etc.) in the case of oxygen combustion, and selection of low-priced dew
point-corrosion-proof materials in the case of heat-exchange appliance of condensed
*1
This project, which is called “development of high-efficiency industrial furnaces, etc.,” consists of three sub-projects:
“combustion control foundation technology,” “development of high-efficiency industrial furnaces,” and “high-efficiency

exhausted gas (economizer using steam’s latent heat recovery). At the moment, they have
potential for becoming effective technologies when separation and recovery of CO2 will be
required as a measure against global warming in the future.
i) Cogeneration
Drivers used for cogeneration are mainly internal combustion engines. The number
of the engines with cogeneration installed, the capacities, fuel used, and the main uses are
shown in the table below. Gas engines and gas turbines are able to effectively use gas
fuels made from solid waste and biomass. At the moment, about 60% of cogeneration
systems are adopting gas firing, which emit less environmental burden including CO2, SOx,
NOx, etc., and are more environmentally-friendly.
97
The total heat efficiency of a cogeneration system is 70 - 80%, which corresponds to
25% of the energy conservation of a thermal power generation boiler system. However,
this value can be obtained under the condition that 100% of the exhaust heat is effectively
used. Accordingly, the point is that the exhaust heat should be applied to facilities that
are expected to demand heat, such as factories, business offices, hospitals, stores, etc.

Fuel cells are regarded as a prospective technology to solve global warming problems
in a future hydrogen-oriented society. This is because fuel cells are applicable to various
fields including vehicles such as passenger cars and buses, cogeneration systems for
households and office buildings, distributed power generation systems installed in places
needing to replace mass-concentrated commercial power generation systems, and power
sources to replace secondary batteries for PCs and cellular phones. However, all types of
fuel cells face challenges to improve durability, prolong life span, and lower cost.
Especially, for the types that require a catalyst, cutting down platinum use and developing
alternative catalysts are big challenges.

(5) Energy conservation measures in the residential sector
1) Outline
Although the household sector has made a progress in terms of energy efficiency of appliances,
its energy demand are also increasing due to the increasing ownership of new appliances and the
growing public demands to seek for more comfortable and convenient lifestyle.
In order to deal with this trend, following collective measures have been launched: the first
measure focuses on improving energy efficiency in machinery and equipment, the second measure
aims to improve the heat insulation performance in residences and buildings and the third one
manages the total energy demand.
In terms of the first one, strict standards have been set by introducing the Top-Runner Program.
At first it targeted the appliances specified in the energy conservation law such as air conditioners
and TVs. Later, the target range was extended to include gas and oil appliances/equipment, vending
machines, etc. with the revision of the law in December, 2004. Moreover, in the field of the hot
water supply system, which accounts for 30% of energy consumption in the households, more
energy-efficient system has been developed and commercialized. And the support programs to
make a smooth introduction in the market are underway.
As for the second measure, the activities to promote the energy conservation labeling program
for residences and the subsidy programs for residences conforming to the energy conservation
standards are being conducted.
The third measure supports the publicity activities to disseminate energy conservation at home,
for instance, on how to best choose energy efficient appliances. And it is backing the testing and
demonstration of home energy management system (HEMS).
iii) Spreading and publicity activities, etc., by the Energy Conservation Center, Japan, the

(4) Other energy conservation measures in the commercial sector
1) Outline
In the commercial sector, the main factor of the increase of energy consumption stems from the
growing floor space of office and commercial buildings, which is triggered by the industrial structure
change. Nevertheless, the awareness to control the energy intensity is relatively low compared to the
industrial sector, whose energy cost directly affects their production costs.
In order to address this problem, like the household sector, following measures have been taken to
improve the energy conservation performance in buildings: (i) establishing energy conservation standards
based on the energy conservation law, (ii) offering low interest loans to the buildings which perform high
energy conservation, (iii) introducing the Top Runner program to help promote energy efficiency for
office appliances, and (iv) implementing the Energy Star program that sets energy conservation standards
for office equipment.
Meanwhile, in June 2002, the Energy Conservation Law was revised and the clause ‘industries
subjected to the Type 1 Designated Energy Management Factory’ was extended to include all industries.
Specifically, office buildings, large-scale retail stores, hotels, hospitals, etc., in the commercial sector
came to be included in this category. Consequently, the business operators newly subjected to the Type 1
Designated Energy Management Factory are required to submit regular reports and mid-to-long term
plans like the business operators already subject to the Type 1 designated Energy Management Factory.
i) Evaluation criteria for building owners regarding the rational energy use in buildings
(Announcement No. 1 by MITI and Ministry of Construction on 20 March 1999)
iii) Outline of the International Energy Star Program System (Announcement No. 258 by METI on
30 March 2001)
b) Support measures
i) As to buildings for business that meet the effort guidelines in evaluation criteria for buildings:
acknowledgement on equipment investment plans, low-interest financing, and grants for paying a
fixed interest rate, based on the Energy Conservation and Recycling Support Law
ii) Financing by the Development Bank of Japan toward environmentally low-burden-type buildings
(“eco-care” buildings) (Ministry of Land, Infrastructure and Transport)
114
i) Familiarize various measures through the Energy Conservation Measures in Summer and Winter,
which were decided by the Conference to Promote Energy and Resources Conservation
Measures.
ii) Dissemination and publicity activities pushed through by the Energy Conservation Center, Japan,
the Construction Environment and Energy Conservation Organization, etc.
By using IT technology, BEMS system promotes and facilitates energy demand management for
commercial buildings. The system ensures recognizing real-time room conditions in buildings by
temperature sensors and/or the optimal operation of lighting and air-conditioning responding to
conditions in the room.

2) Scale of ESCO-Related Market
The ESCO-related market has been growing rapidly in these years. The amount of orders received
decreased in 2004, because the number of large plans in the industrial division decreased. However,
there is still plenty of scope for the expansion of the scale of market as shown below. (Amount of orders
received in 2004: Approx. 37,400 million yen)
The scale of the potential market is expected 2,470 billion yen according to the ESCO Business
Introduction Promotion Study Group of The Energy Conservation Center, Japan.
In the U.S., the scale of market is approx. $2 billion (2000).
3) Future challenge
For further promotion of ESCO business, we have to make efforts to (1) promote the
ESCO business in the public sector, (2) facilitate fund procurement, and (3) improve the
recognition of the business.
With respect to the item (1), we carried out the ESCO business as a model case at the
Ministry of Economy, Trade and Industry in 2004. Furthermore, we will prepare an ESCO
introduction manual for municipalities and hold meetings to explain the guidelines at
municipalities. With respect to the item (2), we will promote use of the low-interest loans of
Development Bank of Japan and the project financing method. With respect to the item (3),
we will hold ESCO business explanation meetings throughout Japan to promote
introduction.

(6) Energy conservation measures in the transportation sector
Specifically, both gasoline- and diesel-powered automobiles have been designated as specified
equipment, under the Law Concerning the Rational Use of Energy, aiming to improve fuel
consumption of automobiles. And publicity activities have been conducted to promote automobiles that
have high energy efficiency performance or “Stop Idling” campaign.
To establish the target values through considering the performance level of equipment
with the best consumption efficiency among presently commercialized products (except
for special products, etc.), in the set division.
ii) Advising, public announcement, commanding, and penalty imposition toward manufacturers of
specified equipment that is significantly below the energy conservation target values (revised in
1998)
iii) Advising, public announcement, commanding, and penalty imposition toward manufacturers of
specified equipment with no indication of energy consumption efficiency.
b) Support measures
i) Spreading and promotion of automobiles which use clean energy as fuel
Preferential measures in terms of the tax rates for purchasing low-fuel-consumption cars and
low-air-pollution cars
Financial aid will be offered to help promote the purchase of clean-energy-automobiles and
low-air-pollution cars, and low-fuel-consumption cars, and for the development of the related
technology.
123
ii) Improvement of energy consumption of individual transportation equipment. Implementation of
investment and financing, etc., to introduce equipment with excellent energy consumption
efficiency
ii) Preparation and distribution of posters and pamphlets, conduction of symposiums, and
information supply through mass media, by related ministries and agencies, and in various fields.
iii) Implementation of activities to acknowledge and enlighten about idling-stop during waiting at
stoplights through Idling-Stop Caravan: cross over Japan, brochures for effects of fuel
consumption reduction, etc.

5.5 Reinforcement of Energy Conservation Measures in Each Sector
(1) Background
At the Third Conference of the Parties to the UN Framework Convention on Climate Change
(COP3), held in Kyoto in December 1997, an agreement was reached on greenhouse gas emissions
reduction targets for developed countries. As part of this agreement, Japan pledged a 6% reduction in
greenhouse gas emissions from the 1990 level, to be achieved in terms of the average annual value
for the 2008–2012 period. Japan’s target for energy-related carbon dioxide emissions, which account
for about 80% of all greenhouse gas emissions, is the achievement of stabilization at the FY 1990
level by FY 2010.
