1.2 Japan’s Energy Situation
As shown in the below figure, Japan’s energy consumption has been steadily expanded especially in thecommercial/residential sector since the 1970’s oil crises period, largely due to convenience-thriving andenergy-needing lifestyles. As for the transportation sector, though the energy consumption was on arising trend until 2001, after that the trend turned downward because of a decrease in freight transportvolume and improvement in fuel economy of cars.

22. ENERGY CONSERVATION POLICIES AND LAWS IN
JAPAN
2.1 Outline of Energy Conservation Policies(1) Brief history of energy conservation policies in Japan
Since the first oil crisis, Japan has made impressive achievements in energy conservation, mostly due
to the combined efforts made by both public and private sectors. In1973 when the first oil crisis
occurred, the oil resource dependency of Japan was as high as 80% of its total primary energy demand.
The oil crisis revealed that the country’s fragility of energy supply and demand structure, but the
government took advantage of the situation as a precious lesson and has made utmost efforts that
subsequently have built a robust supply and demand structure. On the supply level, the diversificationof energy sources has been facilitated by successfully switching to alternative energies such as natural
gas or nuclear power. On the demand level, the industrial sector has played a central role in energy
conservation. As the result of those tireless efforts, the country’s oil dependency has declined to about
44.4% (in 2010), which enables Japan to realize an energy conservation oriented society while staying
as an economic power at the same time. In terms of energy consumption per GDP, Japan has beensuccessful in curbing increasing the consumption, compared with other major developed nations.
Further energy conservation efforts have since been perceived to reach the goal and conserve theenvironment on a global level. More than 90 % of GHG is carbon dioxide and approximately 90% ofcarbon dioxide is emitted from combusting fossil fuels, which means nearly 80 % of GHG emissions
originates from energy use. For that reason, potent and effective energy policies are regarded to be
the key player in resolving the environmental problems.
On the demand level, the government has urged the industrial, commercial/residential andtransportation sectors to promote further energy conservation, even though considerable efforts havealready been taken since the oil crisis. Especially, as the countermeasures for the recent continuing
rising trend of energy consumption in the commercial sector and the transportation sector partly due
to people’s lifestyle changes, the Advisory Committee on Energy and Natural Resources has
reviewed the measures for energy conservation from 2001. The committee put forward additional
measures in 2005 and reviewed them in 2007. The expected minimum saving amount is about 77
kL-oe. Furthermore, the government announced on 23rd September, 2009 that Japan will aim to
reduce GHG emission by 25% by 2020 compared to the 1990 level. With a drastic change in theenergy demand/supply due to the Great East Japan Earthquake and nuclear crisis in Japan in 2011,
the importance of energy conservation is increasing and measures such as revision of energy
conservation act continues to be taken.

(2) Promotion of energy conservation measures
1) Financial support of energy conservation equipment and systems
To promote energy conservation equipment, investment in industry and commerce, loan programs
have been established (low interest loans by Japan Finance Corporation) by the Law for Energy3Conservation and Recycling Support. Additionally, tax reduction measures and the subsidy
programs are provided by the government.

2) Acceleration of development and practical application of energy conservation
technologies
To technologically ensure the practice of energy conservation in future, the R&D of technologies
concerned with energy conservation has been promoted under the cooperation among industries,
the government, and academy.

3) Formulation and application of guidelines based on the Energy Conservation
Law(a) Industrial sector: Guidelines for factories etc. such as standards of judgment and target value
for operating equipment, etc.
(b) Transportation sector: Fuel consumption standards for automobiles and trucks.
(c) Commercial/residential sector: Standards of judgment for buildings and appliances

4) Raising people's awareness of energy conservation by publicity activities(a) Being thoroughly informed of various measures by the Council for Promotion of Energy andResources Conservation Measures, such as “Energy conservation campaign in summer andwinter.”(b) Preparing and distributing posters and pamphlets, holding symposiums and offering
information through mass media.

2.2 Strategic Energy Plan of Japan (Rev. April 2014)
The Strategic Energy Plan of Japan articulates the fundamental direction of energy policy in Japan,
based on the Basic Act on Energy Policy.
The Strategic Energy Plan of Japan is required to be reviewed at least every three years, and was revisedin April 2014 as a first revise after the Great East Japan Earthquake. (Formulation: 2003, revision:
2007, 2010 and 2014)○Introduction
This plan gives a direction of Japan’s energy policies for medium/long‐term (about next 20 years). It
declares a period from now to 2018‐2020 should be a special stage to reform a variety of energy
systems.
Government of Japan (GOJ) will share distress of the affected people caused by the accident at TEPCO’s
Fukushima Daiichi Nuclear Power Plant, and achieve the restoration and reconstruction of Fukushima.
Japan’s energy strategies, which were drafted before the Great East Japan Earthquake, should be
reviewed from scratch, and GOJ should make efforts to decrease dependency on nuclear power as muchas possible.
It is a starting point to reestablish Japan’s energy policies.

(1) Issues related to the energy supply-demand structure in Japan
1) Structural issues faced by Japan
Japan’s energy supply would be easily affected by external factors due to its high dependency onoversea fossil fuel.
Population decline and innovation in energy conservation technology have caused structural

4

changes in Japan’s medium/long‐term energy demand.
Increased energy demand in emerging countries has led rapid increase in natural resources’ prices
and global greenhouse gas emission.
2) TEPCO’s Fukushima Nuclear Accident and issues that become apparent around the time of
the accident
Concerns regarding safety of nuclear power plants and weak public confidence toward GOJ andutilities.
Due to an increase of fossil fuel imports, Japan faces further dependency on the Middle‐East, a risein electricity prices, a rapid increase of greenhouse gas emissions, and an outflow of national
wealth.
Exposed structural defects, such as difference in electricity frequency between East and West inJapan, a lack of emergency system to deliver oil products.
New trend for energy saving by household and industries.
New trend in global energy supply structure such as energy independency of North America due toshale gas, emerging regional differences in energy prices.

(1) Objective
This law aims to contribute to the sound development of the national economy throughimplementing necessary measures for the rational use of energy in factories, buildings,
transportation, 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 fuelresources that would meet the economic and social environment of energy at home and abroad.

(2) Energy defined by the law
The term “energy” in this law means fuels such as oil, flammable natural gas, and coal, as well asheat and electricity produced by using such fuels (excluding electricity generated by the renewableenergy such as photovoltaic cells, wind power, etc.).

(3) Basic policies and obligations of energy users
The Minister of Economy, Trade and Industry (METI) is to establish and announce fundamental
policies aiming at comprehensive promotion of the rational energy utilization in respective fields.
The main energy users in each field have to take into account of the fundamental policy and makeefforts to rationalize their energy use. This is to comprehensively promote the rational use ofenergy through the systematic formulation and the public announcement of the basic matterspertaining to the measures to promote the rational energy utilization.

(4) Measures for factories etc.
Japan’s final energy consumption in the industrial sector and commercial/residential sector
accounts for as much as 75% of the total energy consumption. More proactive actions to promote
the rational energy utilization in factories and business premises are needed and then the Energy
Conservation Law was revised in May 2008. This revised law newly defined “Specified Business
Operators” and “Specified Chain Business Operators and largely expanded the regulatory coverageof total energy consumption in the commercial sector from approximately 10% to 50%.

1) Standards of judgment for business operators
METI is to establish and announce the subject of standards of judgment regarding the measures
to be taken deliberately in order to achieve the goals towards the rationalization of fuelcombustion, utilization and recovery of waste heat, prevention of electricity loss by resistance etc,
and the relevant goals: the subject of standards of judgment are targeted to those who conductbusiness activities and utilize energy in their factories, offices or other workplaces (hereafterreferred to as factories etc.) and are purposed that the rational utilization of energy in factories
etc. would be implemented appropriately and effectively. (Refer to Appendix 2.1 “Standards of
Judgment for factories etc. on Rational Use of Energy” and Table: “Standards and Target Values
for Operating Equipment in Factories etc.”)

16

These standards of judgment present themselves as a set of guidelines for the individual andconcrete measures about the basic matters stated in the basic policy and to guide business
operators to judge and conduct appropriate and effective implementation of the rational energy
utilization in factories etc.

2) Guidance and advice
The competent minister (METI and other minister(s) responsible for the programs of the relevant
factories etc.) may provide business operators with guidance and advice about the rational energy
use with the consideration of the things concerning the standards of judgment when judged
necessary by the minister.

3) Specified Business Operators
Companies who have and run factories or workplaces of which total energy consumption
amounts to over 1,500kL are designated as “Specified Business Operators”

4) Specified Chain Business Operators
Chain business operators such as convenience stores or restaurants who have and run factories,
workplaces or member stores of which total energy consumption amounts to over 1,500kL aredesignated as “Specified Chain Business Operators”“Specified Business Operators” and “Specified Chain Business Operators” are obliged to prepare
and submit a mid-to-long term plan, and report annually the status of their energy utilization to
the competent minister. Also they have to appoint an “Energy Management Control Officer”,
who may be selected from board members having a voice in the business operation, and an“Energy Management Planning Promoter”, who needs to finish the designated energy
management seminars or to be a qualified energy manager. The energy management planningpromoter will assist the energy management control officer practically.

5) Type 1 Designated Energy Management Factories
Factories or workplaces which consume large amount of energy (the total consumption of fueland electricity is 3,000 kL or more per year in crude oil equivalent) and the buildings aredesignated as “Type 1 Designated Energy Management Factories” from the view point that therational energy utilization has to be promoted. The designated criteria were amended andreinforced in April, 2006. The “Type 1 Designated Energy Management Factories” are obliged toappoint either “*Type 1 Energy Managers” or “**Type 2 Energy Managers” depending on theindustrial category to promote energy management in workplaces.

6) Type 2 Designated Energy Management Factories
A factory whose energy consumption is a medium scale (the total consumption of fuel and17electricity is 1,500 kL or more per year in crude oil equivalent) have to promote the rational useof energy in the same way as “Type 1 Designated Energy Management Factories”. Those
factories are designated as “Type 2 Designated Energy Management Factories”. The law
prescribes that “Type 2 Designated Energy Management Factories” are obliged to appoint “Type2 Energy Managers” to promote energy management in workplaces.
*The “Type 1 Energy Managers” must be selected from qualified license holders for energy management by thegovernment. (Regarding “Certified energy manager system”, refer to the item 9) in Page 14.)**The “Type 2 Energy Managers” must be selected persons who finished the designated energy management
seminars or who are qualified energy managers.

Most of the energy consumed in the civil sector is used in buildings. The measures focusing on theinsulation of buildings are highly effective for the rational use of energy. The law provides thefollowing rules for rational energy use in the field of buildings.
1) Obligations of building owners
Construction clients (those who intend to construct or modify buildings) and owners of buildings
must take appropriate measures to prevent heat loss through external walls, windows, etc. and toutilize efficiently the energy for building facilities such as air conditioners, mechanicalventilation systems, lighting, water heaters and elevators, with the basic policies in mind, inefforts to contribute to the rationalization of energy use in the building.
In order to ensure proper and effective implementation of such measures, the Minister of
Economy, Trade and Industry and the Minister of Land, Infrastructure and Transport are toestablish and announce standards which building owners should refer to in making decisions forrationalizing energy use in their buildings. The new standard for the buildings (excluding
residences) was announced on 30 January, 2008. (Refer to Appendix 1.2 “Standards of Judgment
for Buildings on Rational Use of Energy”.) The new standard for houses was announced on 30
January, 2008.
2) Guidance and advice
The competent authorities (Local (prefecture) authority with district construction surveyors andgoverning authorized construction procedures) may, when necessary, give necessary guidance
and advice on building design and construction to the building owners other than residences
while taking into account the standards of judgment which the building owners should refer to in
making decisions. In addition to these rules, the Minister of Economy, Trade and Industry may
give manufacturers of insulation and other construction material necessary guidance and advice
for improving the insulation properties of their construction materials to ensure the improvementof the quality of insulation materials, which constitute a basic element in improving the total
insulation capability of buildings. For residences, the Minister of Land, Infrastructure andTransport is to establish and announce guidelines for their design and construction in accordance

22with the criteria which construction clients and building owners should refer to in making
decisions.
3) Instructions for specified buildings
Under the revision of the Energy Conservation Law in May 2008, buildings having a total
non-residence floor area of “2000m2 or more” and “300m2 or more to less than 2000m2 ” aredesignated as “Type 1 Specified Buildings” and “Type 2 Specified Buildings”, respectively in orderto largely expand the regulatory coverage in the building sector.
Construction clients and owners (Specified Construction Clients, etc.) who intend to construct or
extensively modify “Type 1 Specified Buildings” or “Type 2 Specified Buildings” are obliged tosubmit notification of energy-saving measures to the competent authorities before the start ofconstruction. In addition, after the completion of construction or modification, the Specified
Construction Clients, etc. who submitted the abovementioned notification are obliged to submit
periodical reports on maintenance of buildings with respect to energy-saving measures.
When the competent authority finds energy-saving measures for “Type 1 Specified Buildings” to besignificantly insufficient in consideration of the criteria, the authority will instruct them for
improvement. When the Specified Construction Clients, etc. do not follow the authority’s
instruction for improvement on the measures described in the notification, the authority will
announce to the public the name of the owner in question or order them to follow the instruction.
Also, when the competent authority finds energy-saving measures for “Type 2 Specified Buildings”
to be significantly insufficient in consideration of the criteria, the authority will advise them for
improvement.

(6) Measures for equipment
Automobiles, air-conditioners, and other equipment require large amounts of energy, which aremostly purchased after systematically produced in large quantities. For the rational energy use ofsuch equipment, it is important to call for consumers to act on energy conservation effort in the use,
but a more drastic way is to improve the energy efficiency at a production stage. Based on this idea,
the law provides for various following rules in the use of equipment.
1) Obligations of manufacturers
Those who produce or import energy consuming equipment have to, with the basic policies inmind, ensure the rationalization of energy consumption concerning the equipment by improving
the energy efficiency of the equipment which they produce or import. For automobiles and otherequipment as specified in the Government Ordinance, the Minister of Economy, Trade andIndustry (and also the Minister of Land, Infrastructure and Transport for automobiles) is toestablish and announce standards for energy efficiency improvement which manufacturers mustrefer to in making decisions. The Minister of Economy, Trade and Industry (and also the23Ministry of Land, Infrastructure and Transport for automobiles) may give necessary
recommendations to manufacturers and importers when the government finds a considerable
improvement is needed for their specific products in view of the standards which they must referto 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).

Target standard values are set based on the product in the market having the highest energy
efficiency of all the products of the same group. (“Top Runner Program”)
The years when each of the specified equipment was designated are as follows:
1 April 1999

：Gasoline and diesel passenger vehicles, Air conditioners, Fluorescentlights, TV sets, Copying machines, Computers, Magnetic disk drives,
Gasoline-fueled and diesel powered freight vehicles and Video cassetterecorders

22 December 1999 ：Electric refrigerators, Electric freezers
27 December 2002 ：Space heaters, Gas cooking appliances, Gas water heaters, Oil water
heaters, Electric toilet seats, Vending machines, Transformers
15 July 2003

：LPG passenger vehicles (This is categorized in the passenger vehicles.)1 April 2006

：Microwave ovens, Electric rice cookers, DVD recorders

1 July 2009

：Routers, Switching units

2) Labeling
Equipment described above is obliged to be marked to show its “energy consumption efficiency”
to help consumers selectively purchase highly efficient equipment. The Minister of Economy,
Trade and Industry (and also the Minister of Land, Infrastructure and Transport for automobiles)
is to 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 is to issue a notification of them.

If the minister(s) deem(s) that the labeling does not conform to the notification, he (they) can givea recommendation to the manufacturer, etc., and if the manufacturer, etc. does not comply, theminister(s) can announce to that effect and give an order to take an action conforming to therecommendation.

(7) Measures for transportation
In the transportation sector, which has showed a significant increase in energy consumption during
recent years, the Energy Conservation Law had been imposed only on automobile fuelimprovement. However, under the Revised Energy Conservation Law enacted in April 2006, new24

obligations were imposed on carriers (freight, passenger) and consigners.
Carriers which own 200 or more trucks, 300 or more trains, and so on (Specified carriers) are
obliged to submit mid-and-long term plan and periodic report of the state of energy use to the
Minister of Land, Infrastructure and Transport once a year.
Also, consigners which transport 30 million ton kilo or more per year (Specified consigners) are
obliged to submit mid-and-long term plan and periodic report of the state of energy use to the
Minister of Land, Infrastructure and Transport once a year.

In both cases, when the authority finds that efforts are significantly insufficient or intensity has notbeen improved, advice is given to take proper measures. If the advice is not followed, the authority
will announce to the public the name of the carrier or consigner in question or order them to follow
the advice.

(8) Amendment of the law concerning the rational use of energy
The 1979 law was amended and reinforced in 1983, 1993, 1998, 2002, 2005 and 2008. In theamended version promulgated in May 2008, energy conservation measures were strengthened inboth the commercial sector including offices, convenience stores, etc. and household sector.
The chronicles of revisions of the law are shown in the following table.

“Excellent Energy Conservation Equipment” represents, i) devices,

facilities and systems in addition to “equipment” in general sense, ii) measuring instruments
remarkably contributing to energy conservation, iii) equipment that exploits unutilized resources
such as wastes.
(Sponsored by The Japan Machinery Federation)

2.6 Publicity Activities
In order to promote energy conservation as a nationwide activity, the government has established“Energy Conservation Day” on the 1st of every month, “Energy Conservation Month” in February
and “General Check-up Day for Energy Conservation” on the 1st of August and December.
Educational and publicity activities are conducted in cooperation with the local governments andprivate companies. In those designated days and months every year, various kinds of campaign
activities are held nationwide for promotion of energy conservation. Especially ENEX (Energy &Environment Exhibition) which is one of the biggest comprehensive exhibitions in Japan regarding
energy efficiency and conservation is held in “Energy Conservation Month” every year in February inTokyo.

2.7 Energy Audit Program by ECCJ
Several audit experts make an interview with the persons in charge about the management standards
for the factory or building which is going to have an energy audit. Then, they make an on-site survey
how the facilities in the factory or building are operated. After the survey, they draw up a list of areas
which need remedies and give advice for energy saving potential and needed actions. This energy
audit program is conducted free of charge by the Energy Conservation Center Japan.

37

(1) Energy audit for factories
The total number of factories which received the energy audit service is 4,248 from FY1997 to
2010.
The target factories are ones in the category of “Type 2 Designated Energy Management Factories”
by the Energy Conservation Law and undesignated factories whose annual energy consumption is
100kL or more and less than 1,500kL of crude oil equivalent.

(2) Energy audit for commercial buildings
The total number of buildings which received the energy audit service is 4,272 from FY1997 to2010. During this period, the target buildings were ones in the category of “Type 1 DesignatedEnergy Management Factories”.
From FY2008, the target buildings are ones in the category of “Type 2 Designated Energy
Management Factories” by the Energy Conservation Law and undesignated buildings whose annual
energy consumption is 100kL or more and less than 1,500kL of crude oil equivalent.

3.2 International Efforts to Counter Global Warming
The Intergovernmental Panel on Climate Change (IPCC) is the mechanism that accumulatesscientific knowledge on global warming while debates on the international countermeasures havebeen made in the COPs (Conference of the Parties) of United Nations Framework Convention on
Climate Change (UNFCCC). These two mechanisms are complementing each other.

(1) IPCC: accumulation of scientific knowledge
IPCC is a body organized by the scientists around the world. It was founded in November 1988 by
the World Meteorological Organization (WMO) and the United Nations Environment Program(UNEP) jointly as a place to study global warming problems at a governmental level. In the reportcompiled for 1995, IPCC announced their analysis on the climate change since the 19th century.
According to their findings, global warming had been already occurring due to the increasing
amount of emitted greenhouse gases after the Industrial Revolution etc.

(2) UNFCCC: study of international countermeasures
UNFCCC discusses and performs international countermeasures to the climate change while IPCC
is a place to accumulate scientific knowledge. In UNCED (United Nations Conference on
Environment and Development: commonly named “Earth Summit”) which was held in Rio deJaneiro in Brazil in June, 1992, a large number of nations including Japan signed UNFCCC. The
purpose of this treaty is to stabilize the concentration of greenhouse gases in the atmosphere. As aresult, it is required that the amount of emitted greenhouse gases should be controlled or cut down.
UNFCCC was ratified by 50 countries and went into effect in March, 1994. Following its
effectuation, the COP1 was held in Berlin and the COP2 in Geneva, the COP3 was held in Kyoto to
adopt "Kyoto Protocol", which defined the reduction targets of greenhouse gases in the period from2008 through 2012.

(3) IPCC report on global warming
The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) by theWorking Group I (WGI) published in January, 2007 concluded that the global warming is occurringin the climate system and the increase of the man-originated GHG is the cause of the climatechange. The Fifth Assessment Report (AR5) is being released in four parts between September
2013 and November 2014. It will be the most comprehensive assessment of scientific knowledge
on climate change since 2007 when Fourth Assessment Report (AR4) was released.

Rise of Sea Level between 2090 - 2099 (the end of 21st century)･18-38 cm rise is estimated in the society where the environment and economic activities areprojected to be globally balanced.
･26-59 cm rise is estimated in the society where the high economic growth is achieved byrecognizing fossil fuel as the important source of energy.
Rise of Average World Temperature between 2090-2099 (the end of 21st century)･1.8℃ (1.1℃-2.9℃) rise is expected in the society where the environment and economic
activities are projected to be globally balanced.
･4.0℃ (2.4℃-6.4℃) rise is expected in the society where the high economic growth isachieved by recognizing fossil fuel as the important source of energy.
★Average world temperature has risen 0.74℃ 42
in the past 100 years (1906-2005).

3.3 Kyoto Protocol Coming into Effect
The requirements for the Kyoto Protocol coming into effect included that (1) not less than 55 parties tothe convention ratify the protocol, and (2) parties included in Annex I which accounted in total for atleast 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.
Recent activities of COP/MOP are shown in 3.2 (6).

3.4 G8 Summit(1) Outline of Gleneagles Summit
The 31st Summit (meeting of leaders of major countries) was held in Gleneagles, Scotland, theUnited Kingdom from July 6 to 8, 2005. 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 othercountries with significant energy needs (the outcomes are to be reported to the 2008 Summit inJapan). 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), andincreasing efforts to curtail illegal logging, etc.
The G8 nations agreed to proceed with actions in the following key areas: Conversion to theeffective use of energy; Cleaner power generation for future; Promoting research anddevelopment; Financing the transition to cleaner energy; Managing the impact of climatechange; Tackling illegal logging.

The 34th Summit was held in Toyako, Hokkaido from July 7 to 9, 2008 under the chairmanshipof Prime Minister Yasuo Fukuda. It has been eight years since Japan last hosted a G8 summit(the Kyushu-Okinawa Summit in 2000).
Summary on “Environment and Climate Change” is below:(a) Prime Minister Fukuda stated at the beginning that this was a very important summit,
one that should determine whether humanity can move toward a low-carbon society,severing its dependence on fossil fuels and addressing challenges including global
warming and resource depletion countries.
(b) Long-term Goal
With respect to the goal of achieving at least 50% reduction of global emissions by 2050,
the G8 leaders agreed to seek to share and adopt it with all Parties to the United Nations
Framework Convention on Climate Change.
(c) Mid-term Goals
In order to achieve absolute emission reductions in all developed nations, G8 leadersagreed to implement ambitious economy-wide mid-term goals.
(d) Sectoral Approach
It was recognized that sectoral approaches are useful tools for achieving nationalemission objectives and for reducing GHG emissions.
(e) Climate Investment Funds
G8 leaders welcomed and supported the establishment of the Climate Investment Funds
administered by the World Bank to support the efforts of developing countries, andwelcomed commitments from other donors.
Source) http://www.g8summit.go.jp/eng/news/summary.html(3) Outline of Deauville Summit
The 37th Summit was held in Deauville, France on May 26 and 27.
Regarding environment and climate change, the G8 leaders collaborated with each other andhad discussions from the standpoint of giving political backup to future negotiations for the
COP17. The summary of the discussion is below:
We reaffirm our willingness to share with all countries the goal of achieving at least a 50%
reduction of global emissions by 2050, recognising that this implies that global emissions needto peak as soon as possible and decline thereafter. We are cooperating to that end. As part ofthis effort, we also support a goal of developed countries reducing emissions of greenhousegases in aggregate by 80% or more by 2050, compared to 1990 or more recent years. Consistent
with this ambitious long-term objective, we will undertake robust aggregate and individual
mid-term reductions, taking into account that baselines may vary and that efforts need to becomparable. Similarly, major emerging economies need to undertake quantifiable actions to47

reduce emissions significantly below business-as-usual by a specified year.
The Durban Conference at the end of the year (COP 17) will be another important step forward,
for working towards a comprehensive, ambitious, fair, effective and binding agreement
involving all countries, and including the respective responsibilities of all major economies toreduce greenhouse gas emissions. We need to operationalise the Cancun Agreements and deal
with unresolved issues. We are determined to deliver on our commitments as listed in
Copenhagen, and confirmed in Cancun, and call on all countries, including all major economies,
to deliver on their listed commitments as well. We strongly support South Africa as theincoming Presidency of the Durban Conference and offer our cooperation to make thisConference the success that the world needs in order to successfully combat global climatechange.

At the Camp David Summit, G8 Leaders recognized that the development of and universal
access to environmentally safe, sustainable, secure, and affordable sources of energy is essential
to global economic growth and to their overall efforts to address climate change. As such, they
identified several actions for the G8 to take together: Pursue a Comprehensive Energy Strategy– Safely, Respond to Changing Fuel Mix and Infrastructure, Promote the Sustainable
Deployment of Renewables, Enhance Preparedness for Oil and Gas Supply Disruptions, andAdvance Energy Efficiency, Including Appliance and Equipment Efficiency.

Advance Energy Efficiency, Including Appliance and Equipment Efficiency

Accelerate the global pace of progress on appliances and equipment efficiency byencouraging all governments to:Build on current efforts under the Clean Energy Ministerial, including theSuper-efficient Equipment and Appliances Deployment (SEAD) initiative;

Take steps, including through SEAD, to recognize comparable and transparent test
procedures for energy efficiency in appliances and other consumer products toallow manufacturers to test products once and sell them globally. This effort willdraw on the work of existing standardization bodies to lower non-tariff barriersand
improve the international comparability of energy efficiency policies.



Agree to work together, including through the Clean Energy Ministerial’s Global
Superior Energy Performance Partnership (GSEP), to encourage the use of energy
management systems in industry as well as in government and other buildings andshare related best practices.

4. ENERGY CONSERVATION MEASURES BY SECTOR
4.1 Industrial Sector(1) Energy situation for the industrial sector
The significant energy efficiency improvement has been monitored for the industrial sector in Japan.
In the oil shocks period, the total energy consumption share for all sectors marked at a ratio of 4:1:1
respectively for the industry, commercial/residential, and transportation, but the FY 2006 data
marked the ratio of 2:1:1, approximately, with the industry significantly resulting in lowering its
share and successfully leveled off its consumption. This industrial sector’s positive trend is regarded
attributed to the effect of the regulatory measures of the energy conservation law and manufacturers
and businesses’ accompanying efforts.

(2) Energy conservation policies and measures for the industrial sector
1) History of energy conservation measures for industrial sector
Since the oil crisis, Japan’s industrial sector has played a central role in the efficient use of energy.
Due to the efforts, the sector has successfully maintained almost the same energy consumption level
as in the oil crisis despite the growing output. The sector accounts for nearly 45 % 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 Voluntary Action Plan on theEnvironment”, aiming to promote the efficient use of energy.
As a national policy, the Law Concerning the Rational Use of Energy (Energy Conservation Law)
was revised 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 include all industries. Through therevision, business operators became obligated 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.
In unison with the revision of the Energy Conservation Law, new standards to assess energy use offactories and business offices were enforced on April 1, 2003, which were to control inefficientelectric power facilities, to promote the implementation of the cogeneration system, which is highly
energy efficient and to make good use of ESCO companies.
Starting in 2005, regulations on factories and business establishments, which were implemented
based on the consumption of heat and electricity separately, shall be implemented based on the
integrated energy consumption (crude oil equivalent) of both heat and electricity. The revised law
came into force on April 1, 2006.
Moreover, regulatory structure was changed from regulating each factory or workplace to regulating
the company wide management in 2008. The amendment obliged a company who uses a certain
amount of energy as the whole company to regulate all of its factories and workplaces it has (theregulation is also introduced to a franchise chain such as convenience stores and restaurants,
considering it to be a single company). This revised law came into force partly on April 1, 2009 and51

wholly on April 1, 2010.
In addition, there are financial incentives such as low interest loan programs under the Law forEnergy Conservation and Recycling Support which was ended in 2013, tax reduction measures, andthe subsidy programs to boost investment in developing energy efficient products and technologies
to restructure the country’s energy supply-demand.

(4) Overall factory inspection based on the energy conservation law
An on-site investigation targeting the “Type 1 designated energy management factories” (“overallfactory inspection”) has been conducted since FY 2001 guided by METI. The “Type 2 designatedenergy management factories” were also targeted from FY 2008. In the investigation, theobservance situation of the criterion part of the judgment standards is evaluated. The assessment
results based on the objective standards determine whether any directions should be given. Whenthe achievement in rational use of energy is extremely insufficient, the factory/building is given
instruction to formulate and submit a rationalization plan and to implement it after the on-site
inspection.
The flow diagram of the overall factory inspection is shown below.

(5) Dissemination and promotion of energy conservation technology
1) Categorization of technologies and energy conservation methods with highfeasibility for ripple effects in other fields
The presentation of energy conservation projects held at the Energy Conservation Center, Japan
included a wide range of reports on some excellent examples. Some cases used ingenious ways ofconservation energy or showed originality in selecting improvement themes. Some cases focusedon main improvement technologies. Other cases carried out comprehensive energy conservation
measures which gave special attention to detail, although the measures themselves were quite
ordinary. Introduction of new production methods taking a hint from other fields and measures
based on results of technology development, especially those based on development or
introduction/application technology development of new processes and innovative production
technology have brought large energy conservation effects. The technology and methods among
the cases that will be useful in a wide range of fields can be grouped into the following.
a) Structure and approach for promotion of energy conservationb) Understanding of current conditions by visualizationc) Abolishing the existing ideas and reviewing designed values and management criteriad) Use of surplus energy that has been left unusede) Introduction of cogeneration, improvement of operation methods, raising utilization ratef) Remodeling equipment into or replacing one with high-efficiency equipmentg) Utilization of ESCO projects/Introduction to factories and buildingsh) Energy conservation measures for power receiving system/Measures for demand sidei) Energy conservation measures for compressed air/Energy conservation measures for cleaning
and blowerj) Energy conservation measures for steamk) Energy conservation measures for air conditioningl) Energy conservation measures for hating furnace and melting furnacem) Inverter measuresn) Thermal insulation technologyo) Energy reduction with shorter hours by improving productivity / Reduction of fixed energyp) Integration, consolidation and newly establishment of production process / Reduction of fixedenergyq) Shift of fixed energy to energy proportional to the production / Reduction of fixed energyr) Reduction of production area, minimization of fixed energy area / Reduction of fixed energys) Rationalization and low loss of fixed energy equipment / Reduction of fixed energyt) Optimal control and JIT(Just in Time) “required quantity of energy supply when needed, where
needed” / Reduction of fixed energyu) Mutual utilization of energy among adjacent factories and workplaces / interindustry
collaboration

2) Reduction of the fixed consumption of energy, which is highly-needed from thedemand side
In most of the case reports, details of a preliminary investigation for selection of a task for energy
conservation improvement and narrowing down of themes were described. One of the themesthat were listed up in most of the cases was reduction of the fixed consumption of energy or
reduction of the amount of energy consumption not linked to production, even if such energy was56not termed a constantly required amount of energy.
There are some cases about the consumption of the fixed consumption of energy, namely, thecase that it is high because the existing utility system and low-efficiency energy supply
equipment had been maintained and operated, and another cases that it is large because the excess
equipment had been maintained expecting high economic growth.
In this way, reduction of consumption of the fixed consumption of energy is a cross-sectional
theme. Rationalizing the consumption of such energy is advantageous even if the business pattern
and main products change. According to the data of past cases, technologies to reduce
consumption of the fixed consumption of energy are summarized in the table below. Excellent
energy conservation technologies can be flexibly applied to a wide range of fields, in addition to
being able to reduce energy consumption by rationalization. Evaluation of the energy
conservation technologies is carried out reviewing the following points: high-efficiency, low-loss,
downsizing, weight reduction, adaptability, as well as improvement in user-friendliness including
capability to deal with networking and safety of the technology itself.

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 thedemand 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 utilityenergy 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 andreducing production duration.
1) Cut-down of processing steps by partial integration of production steps2) 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 rate7) Cut-down of duration by raising production efficiency through raising production technology
by basic technology8) 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

57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 tank4) Lowering temperature level of the retention furnace, and adopting induction heating at pouring
gate and additional heating by DC torch5) In the heating process, converting the fixed consumption of energy to the variable energy byadopting 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 process7) Diligently setting control values before rebooting in more detail by stopping equipment to be atstandby time by the minute and second
3. Method 3: Reduction of production space and minimization of the fixed consumption of energy
amount1) Level down of clean room, etc., and raising the cleanliness of each appliance, chamber, andcontainer
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 eacharea, and adopting localized lighting and natural light4) 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 ofenergy1) Adoption of higher efficiency appliances for lighting, air-conditioning, ventilation, watersupply, and other appliances that consume the constant amount of energy2) 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.
5. Other methods :1) Utilization of recovered energy with a total enthalpy heat exchanger, etc., from sensible heat ofproducts in batch processing system for the energy constantly required2) Reduction of pumping energy by rationalizing pressure utilization in decompression andcompression chambers in the same production line3) Converting exhaust heat/coolant in production process to the fixed consumption of energy byusing absorption type refrigerator
4) Reduction of the fixed consumption of energy amount by utilization of internally generated
exhaust heat in clean rooms, etc., for drying5) Reduction of number of appliances consuming the fixed consumption of energy amount by
time-sharing

58

(6) Energy conservation by coordination among factories and workplaces
1) What is “Coordination among factories and workplaces” ?
This is comprehensive energy conservation system by mutual utilization of exhaust heat or waste
in various neighboring factories and workplaces. It includes coordination among different
industries, so it’s also called “Interindustry coordination”. In industrial complexes in various
regions in Japan, there is a growing tendency of the coordination such as mutual utilization of
exhaust heat from factories by multiple bodies.

2) Needs for “Coordination among factories and workplaces”(a)In Japanese industry, each enterprise has promoted energy conservation since the first oil crisis
in 1973 and there has been little room for improvement by effort by each enterprise (or eachtype of business). That is why coordination among factories and workplaces is expected topromote further energy conservation.
(b)More than 30 years passed after Japanese industrial complexes were built. The energy intensity
is decreasing due to aging of the facilities compared to new industrial complexes in Asian
countries. That is why coordination among factories and workplaces is expected to maintainand recover international competitiveness of Japanese industries.
(c) Now Japan has high-efficient cogeneration system and its technical advancement,
new technical concept called “Coproduction”, pinch technology which optimizes
energy use, LCA analysis technique and various system technologies, and advancedenergy management technology. That is why coordination among factories andworkplaces is expected to promote further energy conservation with thesetechnologies.

(7) Dissemination of high-efficiency industrial furnaces and high-efficiency boilers
1) Development of high-efficiency industrial furnaces*1
When heat efficiency is raised by setting a higher preheating temperature of combustion air using
the existing combustion technology, a rapid increase in NOx occurs due to the regional rise inflame temperature. Accordingly, it had been thought that achieving energy conservation andreduction of environmental burden at the same time was impossible. This changed, however, with
the introduction of high-temperature air combustion technology, in which combustion air preheated
to reach over 1,000 degree centigrade is rapidly blown into the furnace and fuel is sprayed into thishigh-speed air stream and burned at high-temperature in a low oxygen density atmosphere. In
this case, the amount of NOx generation decreases by a large margin compared to simple
high-temperature combustion by raising the preheating temperature of combustion air.
In the “Field test project on high-efficiency industrial furnace introduction,”*2 high-temperature air
combustion technology was applied to commercial furnaces. The 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 iscarried out as a project for supporting business entities making efforts to rationalize energy use in*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 fromFY1998 to FY2000, receiving a governmental subsidy for one-third of the cost.

The great difficulty in introduction and popularization of the high-efficiency industrial furnaces isthat 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 andNOx, 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 theworld. Currently, development research to practically apply this technology to non-industrial
combustion and heating facilities that consume a large amount of energy has finished and thetechnology is in the commercialization stage.

2) Development of high-efficiency boilers*1
The efficiency of existing industrial boilers is rather high, achieving 86%-90% (at the low calorificvalue of the fuel). The boilers’ efficiency rate of energy use has also reached a high level among
heat application facilities, but 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.
The development of high-efficiency boilers was carried out focusing on innovative elemental
technologies such as oxygen combustion and heat-exchange appliance of condensed exhausted
gas. The experiment in the pilot plant showed a greater effectiveness compared with in the*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).

existing air combustion boilers, achieving 105.73% of total heat efficiency of the boiler (based on
low calorific value of the fuel, which equals to 98.9% in case of high caloric value).
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 ofheat-exchange appliance of condensed exhausted gas (economizer using steam’s latent heatrecovery) are the future challenges. 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.

(8) Dissemination of cogeneration
Cogeneration, a combined heat and power generation system, is a system in which energy is first
converted into electric energy or motive energy by activating an energy converter (driver) and theexhaust heat that is generated in the energy conversion process is then effectively used for thermalenergy demand (steam, hot water, cold water). In a cogeneration system, the following appliances
are used as drivers:- Internal combustion engine: diesel engine, gas engine, gas turbine- External combustion engine: steam turbine, stirring engine- Fuel cell: PAFC (phosphoric-acid type), MCFC (molten carbonate type), SOFC (solid oxide type),
PEFC (polymer electrolyte type)
Drivers used for cogeneration are mainly internal combustion engines. The number of the engineswith 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 lessenvironmental burden including CO2, SOx, NOx, etc., and are more environmentally-friendly.

The total heat efficiency of a cogeneration system is 70 - 80%, which corresponds to 25% of theenergy conservation of a thermal power generation boiler system. However, this value can beobtained under the condition that 100% of the exhaust heat is effectively used. Accordingly, the pointis that the exhaust heat should be applied to facilities that are expected to demand heat, such as
factories, business offices, hospitals, stores, etc.
The introduction of cogeneration is expected to be pushed forward, because it will improve energy
security and contribute to measures against global warming. The future challenge is to develop
compact and high-efficiency gas engines and gas turbines (micro gas turbines) for civil use. Fuelcells, which are able to generate highly efficient electricity as well as exhaust heat, can make highly
effective cogeneration motors. The future challenge for fuel cells is to lower the price.

4.2 Equipment(1) Energy situation for equipment
In Japan in the field of equipment, the per-household energy consumption has increased, thus
contributing to the country’s steady increase in the household sector. This trend is regarded causedby the country’s societal factors such as lifestyle change leading to more energy consumption,individual’s multiple ownerships of home appliances, and so on.

Source) Prepared from the data by The Japan Electrical Manufacturers’ Association(2) Energy conservation policies and measures for equipment - Top Runner Program
1) Outline of top runner program(a) BackgroundTo diffuse highly energy efficient appliances and vehicles, the revised energy conservation law
makes it obligatory for manufacturers and importers to ensure their products to meet energy-saving
target standards. The government launched the Top Runner Program based on the 1999 amended law
under which the standards are set based on the most energy 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.

(b) Designated products
Target products are ones designated as machinery and equipment which are commercially used inlarge quantities in Japan, consume significant amount of energy on use and intensively required with“energy consumption efficiency”.
(c) Target standard values
As for the designated products, manufacturers and importers etc. are obliged to meet the target
standard values concerning “energy consumption efficiency”. Target standard values are set based on
the most energy efficient product commercially available in the market in a given category.

67

(d) Classification of target standard values
Target standard values are set in classifications considering a variety of models with different sizes
and functions etc. for each product.
(e) Target fiscal years
Target fiscal years by which the target standard value must be achieved are set up through taking into
consideration of future technological development forecasts and the development period of products
and so on, usually in the range of 4 to 8 years from the base fiscal year.
(f) Judgment methods of achievement
In the target fiscal year, achievement of the target is judged based on such indicators as a weighted
average of shipment by product for each product category per manufacturer and importer etc. Top
Runner Standards are different from the concept of MEPS.
(g) Measurement methods
The measurement method primarily uses JIS (Japan Industrial Standards).
(h) Indications
Responsibility is assigned to indicate the “energy consumption efficiency” of the device in catalogs,
on the device itself, etc.

2) Target achievement verification procedures
For each of the companies that manufactures or imports machinery and equipment specified in the
Top Runner Standard, each machinery and equipment category’s weighted average value mustachieve a standard value by the target fiscal year. To confirm the achievement of standards,
questionnaires are distributed to machinery and equipment manufacturers soon after the target fiscal
year and information are obtained on numbers of units shipped, energy consumption efficiency, andthe like in the target fiscal year. The surveys are conducted by the Agency for Natural Resources andEnergy that is responsible for enforcing the Energy Conservation Law.
Weighted average energy efficiency = the sum of {(the number of units shipped domestically foreach 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, areperiodically and continuously collected. For displays on products themselves, submission of nameplates, etc. or retail store surveys are conducted to confirm the implementation.

3) Measures to be taken when the target values are not achieved
If the results obtained from the energy efficiency surveys mentioned in the previous paragraphappear 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 andIndustry (in cases involving cars, the Minister of Economy, Trade and Industry and the Minister ofLand, Infrastructure and Transportation) offer recommendations to the manufacturer in question
as required. Further, if this advice is not followed, the recommendations are made68

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. Targets should be limited to manufacturers whoseorganizational 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 the government decree. If there arecategories that partially fail to achieve goals among the many items, it will not be appropriate toadvise the manufacturer immediately. Instead, reasons why goals were not achieved, othercompanies’ achievement records in the same field, achievement records in other categories of thecompany 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 inspite of small volume in production and import.

4) Standards of Judgment for machinery and appliances under top runner program
The standards of judgment, etc. for manufacturers, etc. regarding improvement of the performanceof “Designated Machineries” pursuant to the provision in Chapter 6 of the Law Concerning the
Rational Use of Energy (the latest amendment in 2008) are defined and notified by the category ofmachinery and appliance. The details of the standards of judgment for machinery and equipment are
shown in the web-site of ECCJ.

For the product categories marked with #, energy efficiency standard values are defined by the energy
consumption efficiency (e.g. km/l), while those without # mark are by the amount of energy consumption (e.g.
kWh/year). In the above table, values of the “Energy efficiency Improvement” indicate the rate of improvement
calculated based on each standard. Example: If the efficiency is improved from 10 km/l to 15 km/l, theimprovement rate is calculated as 50%. (It is not calculated as the improvement of fuel consumption by 33%
from 10 liters down to 6.7 liters for a 100km drive.) ; and if the efficiency is improved from 10 kWh/year to 5
kWh/year, the improvement rate is 50%.

(3) Dissemination and outreach measures for equipment
1) Energy labeling program
The energy-saving labeling system introduced as JIS standard in August 2000 started to give
better information for consumers of energy efficiency of home appliances. As of July 2010, thelabeling is applied to 18 products detailed in the below table. Target years are set per productcategory.
Energy conservation standard

108％

175kWh/year

Target year FY2006
The labeling is colored in orange for a product which doesn't achieve the target standards ofenergy efficiency, while the labeling is colored in green for a product that achieves over 100% of
the target standards. The "achievement rate of energy efficiency standards" is given as apercentage indicating how far the product's energy efficiency is improved from the target value
with the special definitions given as follows for each indication of the labeling information:
Energy efficiency: Measurement process is set per product category. The indicated values are
more efficient with the higher rate of energy performance rate and less energy efficient with thelower rate of energy performance rate.

712) New appliance labeling program
Following the introduction of the original labeling program referred as above, the government
revised the energy conservation law to include the new information requirement of the appliances’
expected electricity cost or fuel usage information. The new comparative rating system which ispresented as five-star rating provides consumers with comparative purchasing with other productsin the same category. Cost information is now required for the designated three products.

4.3 Commercial/Residential Sector(1) Energy situation for the commercial/residential sector
As referred in the previous equipment chapter, the significant improvements in the equipment
energy efficiency have been monitored in Japan. However, contrary to the trend, the country’s final
energy consumption of the commercial/residential sector has been rising. This trend is regarded
attributable to the increasing the number of households, convenience and affluence thriving
lifestyles, the increase of multiple appliances ownership per household, bigger size trend in
appliances, and the increase of high-tech appliances, which use energy heavily.

Source) Prepared from “Comprehensive Energy Statistics”

In the commercial sector, the energy demand has still been increasing in this sector, although
the per-floor space energy intensity has remained roughly flat in recent years shown as below.
This is due to the increase of the total floor-spaces and in FY2012, it showed approximately
42.6% rise from FY1990 in the country in all business types as shown in the next page.

(2) Energy conservation policies and measures for the residential sector
1) Outline of the policies and measures for the residential sector
Although the household sector has made a progress in terms of energy efficiency of appliances, its
energy demand is also increasing due to the increasing ownership of new appliances and thegrowing public demands to seek for more comfortable and convenient lifestyle.
In order to deal with this trend, following collective measures have been launched: the firstmeasure 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 andTVs. 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 hotwater supply system, which accounts for 30% of energy consumption in the households, moreenergy-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 forresidences 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, forinstance, on how to best choose energy efficient appliances. And it is backing the testing anddemonstration of home energy management system (HEMS).

2) Relevant legislation, etc.
a) Measures based on the Law Concerning the Rational Use of Energy- Standards of Judgment for Construction Clients and Owners of Specified Buildings on the
Rational Use of Energy for Houses (Announcement No.1 of METI and MLIT on 30 January,

Month” in February and “General Check-up Day for Energy Conservation” on the 1st of75

August and December which were decided by the Conference to Promote Energy andResources Conservation Measures.
- Educational and publicity activities are conducted in cooperation with the local governments
and private companies through the energy conservation measures in summer and winter.
- Preparation and distribution of posters and pamphlets, conduction of symposiums,
implementation of a house heat insulation construction engineers’ lecture course, andinformation supply through mass media- Implementation of an Energy Conservation Grand Prize, as a system to commend energy
conservation-type equipment for the Commercial/residential sector.
- Preparation for Energy Conservation Performance Catalogue (including 8 appliances: air
conditioners, TVs, DVD recorders, electric refrigerators, electric rice cookers, microwave
ovens, lighting equipment, and electric toilet seats.)(3) Energy conservation policies and measures for the commercial sector
1) Outline of the policies and measures for the commercial buildings
In the commercial sector, the main factor of the increase of energy consumption stems from thegrowing floor space of office and commercial buildings, which is triggered by the industrial structurechange. Nevertheless, the awareness to control the energy intensity is relatively low compared to theindustrial sector, whose energy cost directly affects their production costs. In order to address thisproblem, like the household sector, following measures have been taken to improve the energy
conservation performance in buildings: (i) establishing energy conservation standards based on theenergy 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 officeappliances, and (iv) implementing the Energy Star program that sets energy conservation standards
for office equipment.
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 the commercial sector such as
office buildings, large-scale retail stores, hotels, hospitals, etc.
Moreover, regulatory structure was changed from regulating each factory or workplace to regulating
the company wide management in 2008. The amendment obliged a company who uses a certain
amount of energy as the whole company to regulate all of its factories and workplaces it has (theregulation is also introduced to a franchise chain such as convenience stores and restaurants,
considering it to be a single company). Consequently, the regulatory coverage of total energy
consumption in the commercial sector is expected to increase from approximately 10% to 50%.

4.4 Transportation Sector(1) Energy situation for the transportation sector
The energy consumption in Japan’s transportation sector had increased until FY1996 since the oilcrisis, but the recent data shows that the previous increasing trend stopped and almost leveled off its
consumption. Its major factor is attributed to the increasing number of the ownership of passenger
vehicles. The energy consumption by passenger vehicles accounts for 83 % of the total fuelconsumption in the passenger transportation.

Source) Prepared from “Comprehensive Energy Statistics”
Japan’s vehicle energy performance has significantly improved specifically since the introduction ofa new standard setting process applied for appliances and vehicles called Top Runner Program. As
mentioned in the equipment chapter, as a result of cooperative effort made by manufacturers under
the program, the great improvement in fuel efficiency in those vehicles can be monitoredcomparative to earlier energy performances as shown in the next figure.

Source) Prepared from “Vehicle Fuel Consumption List” by Ministry of Land, Infrastructure, Transport and Tourism

As shown in the below figure, Japan’s per-capita transportation energy consumption marked
lower compared to other major selecting countries, but those countries have successfully
lessened the consumption level, as shown that Germany coming closer to Japan’s lowest
level.

2. INTERNATIONAL COOPERATION
2.1 Outline of Asia Energy Conservation Program(1) Significance of energy conservation cooperation
Energy conservation cooperation is needed from the point of view of enhancing energy
supply-demand structure, solving global environmental problems, promoting international
contribution, reducing destabilizing factors in the Asian countries, deepening the business exchange
between Japan and Asian countries and so on.

1) Improving energy supply-demand structure
Energy demand has been sharply increasing in Asian countries primarily in China and India due
to rapid economic growth, and it causes globally tight market conditions on energy demand andsupply and historical high price of crude oil. Accordingly it is an urgent need to deter a sharp
increase of demand in Asian countries by promoting energy conservation cooperation with thosecountries to improve their energy efficiency.
2) Solving global environmental problems
The promotion of energy conservation cooperation will contribute to solving global
environmental problems in Asian countries.
3) International contribution
Since most of Asian countries are heavily dependent on imported oil and have a fragile energy
supply-demand structure, there is an increasing need for them to promote the energy
conservation. So Japan’s active commitment to respond to their expectations on energy
conservation cooperation is of great significance for improving energy security in Asia.
4) Reduction of destabilizing factors in the Asian economy
Japan has been sustaining profound economic relationships of interdependence with Asian
countries. It is important for Japan’s economy to prevent destabilization of the whole economy in
Asia due to fluctuations in energy price.
5) Deepening the business exchange between Japan and Asian countries
Promoting energy conservation in Asian countries will contribute to business exchange between
Japan and Asian countries through future expansion of the demand for energy-efficient
appliances and facilities.

(2) Future direction of energy conservation cooperation
In order to promote energy conservation in Asian countries on their own initiative, international
cooperation in the energy conservation field will be implemented based on the following ideas:
1) Support for establishing the institutional system in Asian countries･Implementing the establishment of the institutional system concerning energy conservation
through the strengthening of support for the development of human resources including
dispatch of long term experts to Asian countries and reception of trainees in the training course
in Japan, etc.
･Supporting for operation and management of energy conservation centers in various countries
and regions as well as for appropriate operation of the institutional system concerning energy
conservation in Asian countries .
2) Cooperation in the residential/commercial, transportation, and electric power sectors･In addition to the existing cooperation in the industrial sector, extending the cooperation in theresidential/commercial, transportation and power sectors that includes the support forformulating the energy-efficiency standards/labeling system, developing the ESCO system.
3) Support for the business-based diffusion of Japanese-made energy-efficient appliancesand facilities into Asian countries

146

･Supporting the business-based diffusion of energy-efficient appliances and facilities through theJapanese companies’ business activities by promoting dialog among industries and businessmeeting and utilizing policy-based finance and the CDM scheme etc.

4) Collaboration with international organizations, the government and agencies
concerned･Collaborating with international organizations including the IEA and APEC and supportinginternational NPOs which formulate energy efficiency standards and labeling etc.
･Strengthening coordination between the government and agencies concerned in order toimplement effective cooperation.
5) Active utilization of the international framework･Contributing actively to the operation of the international framework including the sectoral
benchmark approach.

(3) Cooperation to individual country in energy conservation field
It is necessary to consider comprehensively the following factors of each country to develop
cooperation in energy conservation field strategically:a) Size for energy demandb) Importance of a country in the energy policy of Japanc) Economic relation with Japand) Commitment and attitude to the promotion of energy conservation
Bilateral policy dialogs will be held with the Asian countries for cooperation. An action plan will

http://www.meti.go.jp/committee/materials/downloadfiles/g60607h11j.pdf<Outline of the Energy Conservation Situation and Policies in Asian and ASEAN Countries>a) China:･China is the world’s largest energy consumer with large potential of energy conservation.
The share of the industrial and residential/commercial sectors in the consumption is large,
but the growth of the consumption is expected in the transportation sector along with therapid spread of motorization.
･19.1% reduction of specific energy consumption/GDP was achieved based on the 20%
reduction of the improvement target in the 11th Five-Year Plan. The new target of 16%
reduction of specific energy consumption/GDP was set in 12th Five-Year Plan. The Energy
Conservation Law went into effect in ’98 and was revised in ’08. Now it is expected that
more effective measures will be implemented.
b) India:･ India is the world’s third largest energy consumer with large potential of energy
conservation. The share of the industrial sector in the consumption is large, but the growthof the consumption is expected in the transportation sector along with the rapid spread of
motorization.
･Since the establishment of the Energy Conservation Law in ’01, energy conservation
measures have been actively promoted such as the development of related legislations andthe strengthening of implementation systems etc. Especially in the industrial sector, PAT(Perform, Achieve and Trade) program was introduced. PAT is a program that enables
each business enterprise to utilize carbon trading system in order to offset their deficiency
and excess of CO2 emission based on the energy consumption after setting the baseline of
specific energy consumption.
c) Thailand:･The primary energy consumption of Thailand is approximately 26% of that of Japan in1472011.
･Thailand has the Energy Conservation Law similar to Japan’s one. It is an advanced
country in energy conservation in ASEAN including the effective implementation ofenergy manager system. Also, measures are implemented in residential/commercial sector
such as labeling system for residential/commercial equipment, dissemination program ofenergy-efficient equipment by an Electricity Generating Authority of Thailand, etc.
d) Indonesia:･The primary energy consumption is approximately 45% of that of Japan in 2011. It has
already become a net-importer of oil with the growth in energy consumption.
･ Awareness on energy conservation has increased in response to the high price of crude
oil and the reduction of subsidy for energy price, and Government Regulation on
Energy Conservation was established in December 2009.
e) Vietnam:･The primary energy consumption is approximately 13% of that of Japan.
･The Energy Conservation Law similar to Japan’s was enacted in January 2011. However,the development of related legislations and implementation systems to implement the law
is still needed. Also, the fact that low price of energy does not provide an incentive forenergy conservation is an issue.

2.3 International Partnership for Energy Efficiency Cooperation(IPEEC)(1) Purpose and overview
IPEEC (International Partnership for Energy Efficiency Cooperation), which aims for promoting
voluntary efforts of participating countries to improve energy conservation such as sharing advanced
practices and exchanging information related to energy conservation measures and technologies, wasofficially launched at the G8 energy ministers' meeting held in Rome in May 2009 since major
economies (China, Korea, Brazil and Mexico) signed its organization requirement as well as G8
countries. Also, India and EU officially signed to join at the first executive meeting held in
September 2009 and the second executive meeting held in January 2010, respectively.

(2) Activities
The following activities are expected to be undertaken:･ Development of energy efficiency indicators, collection of best practice and enhance data150

collection.
･ Exchange information on sectoral and cross-sectoral approach to improve energy conservation･ Development of public-private partnerships in the major energy consumption sector･ Joint research and development of major energy-saving technology･ Promoting the diffusion of energy saving products and services･ Efforts to be determined by individual participating countries
This partnership is intended to provide a forum for discussion and information sharing. Thisdeclaration is not an international treaty and without restriction by law.
In addition to the Japan-led ”Energy Management Action Network (EMAK) (refer to (3) below)”,
there are key projects such as “Sustainable Building Network : SBN, led by Germany”, “Worldwide
Energy Efficiency Action through Capacity Building and Training : WEACT, led by Italy”,“Assessment of Energy Efficiency Finance Mechanisms, led by India”, “Improving Policies throughEnergy Efficiency Indicators, led by France”, “Global Superior Energy Performance Partnership:
GSEP” and “Super-efficient Equipment and Appliance Deployment:SEAD”, led by USA.

(3) Energy Management Action Network (EMAK)
Energy Management Action Network (EMAK) is a Japan-led project which Japan proposed as oneof the tasks under IPEEC in order to promote cooperation on energy conservation. The task of
EMAK is to create a robust forum to promote energy management practices in industry by utilizing a
network of different actors. EMAK interconnects policy makers and industry practitioners in chargeof energy management, who are the two different major actors. Networking these key actors serves
as a platform which enables them to share the best practices on policy frameworks, human resource
development, as well as the state-of-art energy management systems and practices including energy
management system.
The first workshop was held in Paris in January 2010. The purposes of this workshop were to shareenergy management practices and to discuss the design of effective and useful concept of EMAK.
Then in the second workshop held in Washington, D.C. in May 2010, the presentations provided
insights into the energy management institutions and regulatory systems of various countries, andprovided a learning experience for all participants. Also, the sessions included one focused solely on
how the introduction of ISO50001 can facilitate energy management in a company and support theachievement of the goal of EMAK.
The third EMAK workshop was held in Guilin City, China on 15th November 2011. The workshop
was co-organised by the Government of China and the Government of Japan in cooperation with the
IEA and the IEEJ under the framework of IPEEC. This workshop had a large group of attendees
from China and over ten other countries. The sessions focused on heavy industry sectors such as iron& steel and concrete, as well as the role of small and medium enterprises.
Also, the first webinar was held on 12th March 2012 to share the outcome of EMAK activities.
Subsequently, the third workshop was held in Keirin, China in 2011 and the fourth workshop washeld in Tokyo in 2013. Most recently, the fifth workshop was held in Sydney Australia in 2014
