Ministry of Environment reviews emission coefficient of fuels: Decrease for thermal coal and increase for LNG
On 16 December, MOE(Ministry of Environment) presented the review of emission coefficient for using fuels in the calculation, reporting and publication system for greenhouse gas emissions at the panel of experts. For the thermal coal, CO2 emission coefficient is decreased by 0.01 to 2.32 ton per 1 ton and LNG is increased by 0.09 to 2.79 ton from the current level.The review was based on the emission coefficient in the national inventory report submitted to annually to the UNFCCC ( United Nations Framework Convention on Climate Change) secretariat. It was approved by the committee members and will be reflected in the system in FY2023.
On the same day, the review was presented at the study group on calculation method in the calculation, reporting and publication system for greenhouse gas emissions. While the emission coefficient in the national inventory report which summarizes the information on greenhouse gas emissions has been updated as needed, it had not in the calculation, reporting and publication system. As it has caused a gap in data, review of emission coefficient was determined at the study group on March 2022 and it will be reviewed every five years.
In the review, emission coefficient of A type heavy oil is increased by 0.04 to 2.75 ton and LPG is decreased by 0.01 to 2.99 ton. No objections were raised by the committee members and the final decision will be made in consideration of the opinions from related organizations.
The interim report on the partial revision of the calculation, reporting and publication system including the revision of emission coefficient was also presented on the same day. The report also included a policy that the emission coefficient of gas and heat, which are uniform under the current system, will be announced for each business operator on the request of supplier.
The MOE also presented the agenda in the study group after FY2023. The discussion points included the calculation method of greenhouse gas when using CCS(Carbon dioxide Capture and Storage).
