According to Government regulations, businesses under Decision 01/2022/QD-TTg must submit the first grassroots greenhouse gas inventory report before March 31, 3. This report only includes 2025 greenhouse gas inventory results, not requiring 2024 data.
With only 2 months left until the new year 2024, have businesses grasped the greenhouse gas inventory process guided by the Government? Below are 9 general steps to implement this regulation.
Step 1: Determine the greenhouse gas inventory method
The field-level greenhouse gas inventory method is based on the 2006 National Greenhouse Gas Inventory Guideline (hereinafter referred to as the 2006 IPCC Guide) and the 2019 National Greenhouse Gas Inventory Guideline. completed for IPCC 2006 (hereinafter referred to as IPCC 2019 guidelines).
The detailed inventory method for each sub-sector is carried out according to the provisions in Appendix I.1 of Circular 17/2022/BTNMT.
Step 2: Select the greenhouse gas emission coefficient
Emission factors used to inventory field-level greenhouse gases are applied according to the emission factor list published by the Ministry of Natural Resources and Environment.
Step 3: Collect greenhouse gas inventory data
Operational data for sector-level greenhouse gas inventories are referenced from IPCC 2006 and IPCC 2019 guidelines.
Operational data sources are collected from the General Statistics Office and relevant agencies at both central and local levels.
Principles, procedures and forms for collecting operational data are implemented according to the provisions in Appendix I.2 of Circular 17/2022/BTNMT.
Step 4: Calculate greenhouse gas emissions
The calculation of sector-level greenhouse gas emissions is based on the greenhouse gas inventory methods specified in Step 1.
The results of the greenhouse gas inventory are calculated and synthesized on the basis of forms on activity data, emission coefficients, and global warming coefficients for the emission and absorption sources included in the greenhouse gas inventory. of the waste sector.
Step 5: Control the quality of greenhouse gas inventory
The process of quality control of greenhouse gas inventory in the waste management sector is based on the IPCC 2006 guidelines and IPCC 2019 guidelines.
Activities in the process include:
+ Check the comprehensiveness, accuracy and completeness of data
+ Test hypotheses and criteria for selecting activity data, emission factors, and conversion factors;
+ Check data entry errors and reference documents;
+ Check the data synthesis;
+ Check the continuity of data;
Step 6: Ensure the quality of greenhouse gas inventory
The process for ensuring the quality of greenhouse gas inventory in the waste management sector is based on the IPCC 2006 and IPCC 2019 guidelines.
The activities in this process are carried out by agencies that are not involved in the sector-level greenhouse gas inventory process.
Step 7: Assess greenhouse gas inventory uncertainty
Uncertainty assessment of field-level greenhouse gas inventory results is based on IPCC 2006 and IPCC 2019 guidelines.
– Determine the uncertainty of operational data, emission factors, and calculation results during the field-level greenhouse gas inventory process.
– Develop a table summarizing the uncertainty of field-level greenhouse gas inventories.
Step 8: Recalculate the greenhouse gas inventory results
Recalculation of the results of the previous period's sector-level greenhouse gas inventory is carried out in the following cases:
– Discovered errors in the results of calculating greenhouse gas emissions.
– There are changes in greenhouse gas quantification methods, operational data and emission factors.
Step 9: Develop a greenhouse gas inventory report
The field-level greenhouse gas inventory report is developed according to Form No. 04, Appendix II of Decree 06/2022/ND-CP regulating greenhouse gas emission mitigation and ozone layer protection.
