I-4. Transition of Energy Consumption in the Transportation Sector
Factors for the Increase in Energy Consumption
for Private Passenger Vehicles
  • Energy consumption for private passenger vehicles marked a drastic 63% increase over 12 years from FY1990.
  • The trend is mainly attributed to the increase in household ownership of passenger vehicles extending total driving distance and increased vehicle weights, compromising actual fuel economy.

Overview of Energy Conservation Measures
for Transportation Sector
  • Submission of energy-saving measure plans and reports on the energy used shall be compulsory for consigners as well as carriers [in conformance with the Revised Energy Conservation Law] (in cooperation with the Ministry of Land, Infrastructure and Transport)
  • Introduction of high-efficiency maintenance and the promotion of technological development (in cooperation with the Ministry of Land, Infrastructure and Transport)
  • Promotion of conversion of commuters' means of transportation from their private cars to public transportation with the cooperation of passenger transportation companies and factories [in conformance with the Revised Energy Conservation Law] (in cooperation with the Ministry of Land, Infrastructure and Transport)
  • Improvement of physical distribution bases for enhanced physical circulation and distribution efficiency, use of IC tags, assistance for realization of cooperative transportation/distribution systems [in conformance with the Law for Improving Physical Circulation and Distribution]
  • Establishment of fuel economy standard for large-sized trucks and the like [in conformance with the Energy Conservation Law] (in cooperation with the Ministry of Land, Infrastructure and Transport)

II-1. Overview of Energy Conservation Measures
Overview of the Law Concerning the Rational Use of Energy
The revised version of the law with additional provisions of measures for transportation etc. was promulgated in August 2005 and will be enforced in April 2006.

Fundamental policies: The Minister of Economy, Trade and Industry shall make public fundamental policies related to the measures to be taken by energy users etc. for the rational use of energy

Factories and Business Establishments Transportation Residences and Buildings Measures for Machinery and Equipment
Publication of responsibilities and criteria for enterprises

Type 1 Designated Energy Management Factory
(Annual energy use: 3,000 kl)

  • Appointment of Energy Manager
  • Submission of mid- and long-term plans
  • Submission of periodical reports on energy use

←When the Ministry finds the rational use of energy to be significantly insufficient in consideration of the criteria, it shall instruct, announce to the public, or order (penalize) the particular factory

Type 2 Designated Energy Management Factory
(Annual energy use: 1,500 kl)

  • Appointment of a qualified person for energy management of type 2 designated factory
  • Submission of periodical reports on energy use
  • The divisions of heat and electricity, which were separated in the past, shall be integrated for control purposes (represented in crude-oil equivalent).

←When the Ministry finds the rational use of energy to be significantly insufficient in consideration of the criteria, it shall advise the factory in question

[Modified points of the law]

  • The divisions of heat and electricity, which were separated in the past, shall be integrated for control purposes in view of today's actual circumstances at factories and business establishments.
  • Consequently, the level of energy use as the standard to designate factories was lowered to increase the number of factories and business establishments subject to designation. (From approximately 10,000 to 13,000)
  • Establishment of registered examination body system. (If a factory or business establishment is examined and verified by a registered examination body, the factory or the like shall be excused from the submission of periodical reports.)
  1. Carriers (Freight, passenger) Publication of responsibilities and criteria for enterprises Designated carriers
    (Vehicle ownership: More than 200 trucks or more than 300 items of rolling stock or the like)
  • Submission of mid- and long-term plans
  • Submission of periodical reports on energy use

←When the Ministry finds the rational use of energy to be significantly insufficient in consideration of the criteria, it shall advise, announce to the public, or order (penalize) the operator in question.

  1. Consigners Publication of responsibilities and criteria for enterprises Designated consigners
    (Annual cargo: 30 million ton kilometers)
  • Submission of plans
  • Submission of periodical reports on energy use required for consignment transportation

←When the Ministry finds the rational use of energy to be significantly insufficient in consideration of the criteria, it shall advise, announce to the public, or order (penalize) the consigner in question.

[Modified points of the law]

  • Measures for the transportation sector are newly added. (Periodical reports shall be prepared from April 2007.)
Publication of responsibilities and criteria for owners of residences or buildings and clients for construction
  • The clients, those who will modify buildings, and the owners of specified buildings shall be instructed or advised in connection with the design, construction, and maintenance of the buildings.
  • The Ministry of Land, Infrastructure and Transport announces guidelines for the design and construction of residences.

Designated buildings
(Buildings including residences having a total floor area of 2,000 m2 or larger)

  • Submission of notification of energy-saving measures to the competent authorities* by the clients and owners (specified clients etc.) who will construct or extensively modify designated buildings.

←When the competent authority finds the energy-saving measures to be significantly insufficient in consideration of the criteria, the authority shall advise or announce to the public the name of the owner in question.(* Competent authorities: Prefectural authorities, with district construction surveyors, governing construction authorization procedures)

  • Periodical reports on maintenance of buildings with respect to measures by the designated clients etc. of buildings who have submitted notification to the competent authorities

←When the competent authority finds energy-saving measures to be significantly insufficient in consideration of the criteria, the authority shall advise the client etc. in question.

[Modified points of the law]

  • Owners of buildings are newly designated as those subject to the measures (maintenance, repair, and modification)
  • Notifications in the case of extensive modifications are also designated compulsory.
  • Residences having a total area of 2,000 m2 or larger are included in the category of designated buildings, with requirements for notification newly designated.
Responsibilities for manufacturers or importers of energy-consuming equipment

Designated equipment Publication of criteria
(Top Runner standard)

  • Energy conservation standards of passenger vehicles, air conditioners, television, etc., which are required to be higher than the performance of the respective top-running brands of commercialized products.
  • LCD and plasma televisions, DVD recorders, and heavyweight vehicles are newly listed as products subject to the measures.

←When the Ministry finds it necessary to improve performance significantly, it shall advise or announce to the public.

Provision of information
Information for general consumers
  • Promotion of distribution of energy-saving devices as well as provision of energy-saving information to users by power/gas companies and publication of achievements
  • Promotion of presentation of easy-to-understand energy-saving information over the counter at home appliance shops (annual power consumption values, fuel economy, etc.)

[Modified points of the law]

  • Responsibility for provision of information is newly specified
In conjunction with the systems related to the calculation, reporting, and publication of the emissions of GHG specified in the Partially Modified Law Concerning the Promotion of Measures against Global Warming enacted in the current Diet session, emissions of energy-originated carbon dioxide is required to be obtained on the basis of the data in the periodical reports submitted in compliance with the Energy Conservation Law.
