JP-8:Mandatory GHG Emissions Reporting
Japan introduced in 2005 (effective in April 2006) the Mandatory Greenhouse Gas Accounting and Reporting System. This system requires specified entities (which emit GHG emissions above a defined thresholder) to calculate their GHG emissions and report the results to the Government.
Japan introduced in 2005 (effective in April 2006) the Mandatory Greenhouse Gas Accounting and Reporting System based on the revised Act on Promotion of Global Warming Countermeasures (Act No. 117 of 1998). This system requires specified entities (which emit GHG emissions above a defined threshold) to calculate their GHG emissions and report the results to the Government.  
The main objective of the system is to promote voluntary emissions-reduction efforts of emitters through assessment of the current GHG emission levels.
Policy Information Expand this section for information on the key features of the policy, such as its date of introduction, categorization, main objective(s) and linkages with other policies.

Primary Objective: GHG Emissions
The main objective of the system is to promote voluntary emissions-reduction efforts of emitters through assessment of their current GHG emission levels.
Driver of energy consumption or emissions affected by policy: GHG emissions
Implementation Information Expand this section for information on targets, monitoring, verification and enforcement regimes, and implementation requirements and tools.
Quantitative Target? no
Progress Monitored? yes
Verification Required? no
Sanctions: In cases of failure to report or falsified reporting, offenders can be fine of up to 200,000 yen.
Requirements on the Target Group
Companies and businesses that emit above 3,000 tCO2eq or consume more than 1,500kl (crude oil equivalent) of energy per year must calculate and report their GHG emissions.
Support by Government
A manual for calculating and reporting Greenhouse Gas emissions was released by the Japanese Ministry of Environment in November 2006 and the same ministry issued Environmental Reporting Guidelines in 2007
