Revising the calculation method of greenhouse gas emissions
Ministry of Environment (MOE) will revise the calculation method of GHG emissions for the first time in 15 years in the Publication system of the greenhouse gas emissions by the companies. It aims to appropriately reflect the corporate activities in light of changes in the business environment. Firstly, it will be incorporated into the system that when consumers purchase FIT (Feed-in Tariff for renewable energy) non-fossil certificates, they can appropriate them as emission reductions.
On 17th January, MOE established “the Study Group on the calculation method of the mandatory system for greenhouse gas calculation, reporting and publication” (chairman: Yuichi Moriguchi, the director at National Institute for Environmental Studies) and began discussions.
The system requires all the company that use more than 1,500kL of the energy (crude oil equivalent) per year in all her working places to announce their greenhouse gas emissions.
It was the first time to review the calculation method of emissions since the system was launched in 2006. The target activities and emission factors for calculation will be revised according to the actual situation.
Since consumers could purchase FIT certificates in the non-fossil energy value trading market of the Japan Electric Power Exchange (JEPX) from November 2021, this revision will be reflected in the system. The companies can subtract the value obtained by multiplying the electricity (kwh) shown in the purchased FIT non-fossil certificates by national average coefficient of CO2 emission by power generation.
