Law concerning the Rational Use of Energy (1979) and Act on Promotion of Global Warming Countermeasures, 1998

Japan Current 1998

The energy conservation law was introduced in Japan in 1979 following the oil crises in the 1970s. It law has served as the foundation of energy demand policy and has been revised many times. It among others addresses energy-related reporting by companies. It was followed by the Act on Promotion of Global Warming Countermeasures in 1998 (post-Kyoto climate conference) as the first climate-dedicated law in Japan. Under this legislation companies that consume a certain amount of energy are obligated to report the amount of energy consumption and greenhouse gas (GHG) emissions to government. The reported information is made public. Government has also issued the GHG Monitoring and Reporting Manual, which gives detailed guidance on how to calculate emissions. Many companies refer to this manual. The legislation has therefore indirectly helped increase the comparability of GHG data in sustainability reporting.
