      The law covers all sectors. In the industry sector, it addresses factories that consume more than 1500kL oil equivalent energy annually, covering 90% of the factories in this sector. The target set by this law is a 1% average annual reduction in energy consumption, enforced by a fine of JPY1m (USD8,495) in case of violation.

      In the other sectors, the law imposes a set of energy efficiency standards for vehicles, appliances, and buildings, as well as performance labels. This law also set the Top Runner Program which covers different sectors and encourages energy efficiency.
