- Climate change refers to a significant change in the climate system that have been observed and measured for an extended period of time. These unusual changes from the variation of greenhouse gas concentration are caused by human activities. In this regard, it is very important to understand the sources of emissions and absorption, and precisely calculate the total amount of emissions and absorptions from each sources. In other words, precise calculation of national greenhouse gas inventory (greenhouse gas statistics) is essential to establish and implement relevant policies. National greenhouse gas inventory was prepared, analyzed and announced by the Ministry of Knowledge Economy (formerly the Ministry of Commerce, Industry and Energy) in accordance with the Framework Act on Energy, however the national greenhouse gas inventory faced its limitations as it was calculated without consistent and unified standards.

- Hence, the Ministry of Environment has conducted the national greenhouse gas inventory in accordance with the Framework Act on Low Carbon, Green Growth (hereafter referred to as ‘Green Law’) since 2010. The principle and system of greenhouse gas inventory management and the installation of the Greenhouse Gas Inventory & Research Center of Korea is specified in this law, and the establishment of a clear and effective ‘National Greenhouse Gas Information Management System’ was made available.  

Inventory Preparation System

- The preparation of national greenhouse gases inventory is based on the Green Law. The preparation and submission are conducted by the responsible organization and the verification of the submitted inventory is conducted by the center. The deliberation and vote to determine the final national greenhouse gases were conducted by the ‘National Greenhouse Gases Statistics Management Committee’ (hereafter referred to as “Management Committee”), the working level consultation between the ministries by the ‘National Greenhouse Gas Statistics Working Level Council’ (hereafter referred to as “Working Level Council”) and the technical advice by the ‘National Greenhouse Gas Statistics Technical Committee’ (hereafter referred to as “Technical Committee”). Then, the system was developed to prepare national greenhouse gases inventory with a more reinforced verification stage.

Process of Inventory Preparation

- The first step to prepare national greenhouse gas statistics is that the center should provide the Guidelines for the Measurement, Reporting, and Verification (MRV) of National Greenhouse Gas Statistics to each  responsible organization. The center is responsible to decide and provide the MRV guideline which is modified, supplemented and confirmed through the deliberation of the Management Committee while reflecting the improvement of the problems occurred when preparing the ‘National Inventory Report (NIR)' and ‘Common Reporting Format (CRF)’ of the previous year by the end of February to each of the responsible organization. In the meantime, the designated estimating organization in each area by each responsible organization should estimate the NIR and CRF based on the same guideline and each responsible organization should submit the prepared NIR and CRF by the 30th of June.

- Submitted NIR and CRF will be verified from July to the end of August, and, the center should prepare the verification report based on the final result. The first stage of verification will be conducted by the specialists in each area internally, and the second stage of verification will be conducted by the outside specialists who were not involved in the actual statistics preparation if needed. Each responsible organization should submit the modified and supplemented NIR and CRF based on the verification report to the center by the end of October. After then, they will be announced on December after the review of the Technical Committee, consultation of the Working Level Council and final deliberation and determination of the Management Committee is completed.

- National greenhouse gas statistics applied the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (1996 IPCC GL), Good Practice Guidance and Uncertainty Management for National Greenhouse Gas Inventories (GPG 2000), and Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF) that was developed by IPCC as the estimation method. Also, the sectors involved in the statistics estimation are divided in Energy, Industrial Process, Agriculture, Waste, Land-Use, Land-Use Change and Forestry (LULUCF), and the greenhouse gases included in the estimation are CO2, CH4, N2O, HFCs, PFCs, SF6. They are known as the 6 major greenhouse gases in Kyoto Protocol and direct greenhouse gases. CO2eq., Carbon Dioxide Equivalent was used as the estimating unit and the Global Warming Potential was used as the conversion standard. In addition, the indirect greenhouse gases such as NOx, CO, Non-methane Volatile Organic Compounds (NMVOC), sulphur dioxide (SO2) are estimated and reported as well.
