Understanding the greenhouse gas inventory process is very important. The article below, GREEN IN will guide greenhouse gas inventory in the most correct and detailed way.
Theo Decree No. 06/2022/ND-CP of the Government on Regulations on greenhouse gas emission reduction and ozone layer protection, the process of conducting a grassroots greenhouse gas inventory is carried out in the following steps:
1. Step 1: Determine the scope and method of greenhouse gas inventory
Define scope of operations: Comply with ISO 14064-1:2018 and Part 1 of National Standard TCVN ISO 14064-1:2011, the content includes:
- Clearly identify activities that cause greenhouse gas emissions
- Classify greenhouse gas emission sources into direct and indirect emission sources.
Determine the method: Comply with the provisions in Appendix II.1 Circular 17/2022/TT-BTNMT.
2. Step 2: Select greenhouse gas emission factor
The coefficients in calculating greenhouse gas emissions are applied according to the list of emission coefficients announced by the Minister of Natural Resources and Environment. Depending on each field in which the facility operates, there will be separate coefficients.
3. Step 3: Collect activity data for greenhouse gas inventory purposes
Activity data for each grassroots greenhouse gas emission source are selected and collected according to the provisions of Appendix II.2 Circular 17/2022/TT-BTNMT.
4. Step 4: Calculate greenhouse gas inventory results
The process of calculating greenhouse gas inventory emissions is based on the provisions of Article 16 Circular 17/2022/TT-BTNMT. The calculation will be based on forms containing data from input data, activity data, emission factors, emission volume, global warming factor... Based on this, you can calculate greenhouse gas inventory in the most specific and accurate way.
5. Step 5: Control and ensure the quality of greenhouse gas inventories
This activity is performed based on “National standard TCVN ISO 14064-1:2011, Part 1: Specification and guidance for quantifying and reporting greenhouse gas emissions and removals at the facility level.” The process includes the following steps:
- Identify and review the responsibilities and authorities of those responsible for implementing greenhouse gas inventories.
- Identify, implement and review appropriate training for members conducting greenhouse gas inventories.
- Identify and test the operating boundaries of the facility.
- Identify and examine sources of greenhouse gas emissions.
- Select and test quantitative methodologies, including greenhouse gas activity metrics and greenhouse gas emission factors.
- Review the application of greenhouse gas inventory methods to ensure consistency across facilities.
- Use, maintain and calibrate measuring equipment.
- Build and maintain data collection systems.
- Periodically check the accuracy of measuring instruments.
- Conduct internal assessments and periodic technical audits.
6. Step 6: Assess the uncertainty of inventory results
At this step, the grassroots assessment will be carried out according to the provisions of Appendix II.3 Circular 17/2022/TT-BTNMT.
7. Step 7: Recalculate inventory results
- Recalculation of results is only performed in one of the following cases:
- Changes in operating boundaries result in changes in emission sources as well as changes in the operating data of the affected facility.
- Changes in greenhouse gas emissions due to changes in ownership and operation of facilities.
- There are errors in the selection and use of greenhouse gas emission calculation methods and the application of emission factors.
- Detecting errors in collecting and processing facility operating data leading to greenhouse gas emission calculations varying by more than 10% compared to previously reported results.
Note: The recalculation results will be clearly recorded in the grassroots greenhouse gas inventory report in the next reporting period.
8. Step 8: Build the report
Report construction is based on Form 06, Appendix II Decree 06/2022/ND-CP On regulations on greenhouse gas emission reduction and ozone layer protection, submit to the competent authority of the Provincial People's Committee for appraisal according to regulations.
The inventory results, after being appraised by the relevant ministries and branches, will be sent to the Ministry of Natural Resources and Environment online on the database system.
With the current urgent situation of environmental pollution, greenhouse gas inventory is considered an urgent activity to reduce the amount of toxic emissions into the environment. Accordingly, understanding the instructions for greenhouse gas inventory will help businesses be more proactive in the working process as well as choose appropriate solutions for the business.
