Basic Structure of Energy Conservation Policy
Incentives
• Subsidies for introducing equipment
• Tax incentive• Subsidize interest
payment• Subsidize R&D
Regulation
• Energy Conservation Law
• Mandatory Labelling
Subsidize 1/3 of the total cost on purchasing energy-efficient equipment and repairing.
Not only big companies factories but also small companies and offices such as hospitals utilize the subsidies.
E.g. : High efficiency heat-pomp High efficiency boiler Co-generation
Factory
Building
Lighting equipment
Industrial Furnaces
E.g. : High efficiency lighting ( including: LED)
transformer
Hot water supply system ( high-efficiency
generator )
Air conditioner
E.g. : High-efficiency Air conditioner
Others
E.g. : Refrigerator ・ refrigerate equipment
E.g.: High-efficiency transformerE.g. : High-efficiency industrial furnaces

3) Annual reports to the Government by business operators with 1,500 or more kl/yr energy consumption 15,000 manufacturing plants & officesReduction efforts of 1% per year
2) Energy efficiency standards for buildings and houses
1) Top runner standards for household appliances , equipment, automobiles etc.

Judgment made with weighted average for each product category.
The program requiring manufacturers and importers to fulfill the efficiency targets within 3 to 10 years.
Targets are set, based on currently commercialized products with best energy consumption efficiencies, namely top runner products.
Encourages competition and innovation without price hike.Image of Top Runner Program
