GHG Inventory Process for the Forestry and Forest Land Sector
Climate change is a pressing global issue, and the GHG inventory is regarded as one of the key solutions for reducing environmental impact. In the forestry and forest land sector, a GHG inventory not only helps assess greenhouse gas emissions and removals but also supports the development of more effective forest protection strategies.
Greenhouse Gas Inventory in the Forestry and Forest Land Sector
What is a greenhouse gas inventory?
A GHG inventory is the activity of collecting data, calculating, and determining the amount of greenhouse gases emitted and removed in a specific year. Pursuant to Circular 23/2023/TT-BNNPTNT, the GHG inventory is carried out to assess the emission levels of gases such as Carbon dioxide (CO2), Methane (CH4), and Nitrous oxide (N2O). In particular, CH4 and N2O gases are converted into carbon dioxide equivalent (CO2e), following the guidance of the IPCC (Intergovernmental Panel on Climate Change).
Factors to consider in the forestry GHG inventory
To carry out a GHG inventory in the forestry sector, a number of important documents must be collected. According to Article 12 of Circular 23/2023/TT-BNNPTNT, these documents include:
- Reports on forest survey and inventory results, including the nationwide forest status each year and statistical data from the Ministry of Agriculture and Rural Development.
- Information on the area and use status of forest land, from statistical data of the Ministry of Natural Resources and Environment and other statistical agencies.
Spatial data on forest area, areas with changes in forest status, and the conversion of forested land to other land types must all be collected and calculated to support the inventory process.
Subjects of the forestry GHG inventory
During the inventory process, the main subjects to be monitored are:
- Forested land: This is an important land type that directly affects the amount of CO2 removed and emitted.
- Non-forested land converted into forested land: These areas play an important role in reducing the amount of CO2 in the atmosphere.
- Forested land converted into non-forested land types: This conversion must be strictly controlled because it can increase greenhouse gas emissions.

The GHG inventory cycle
The GHG inventory is conducted periodically every two years, starting from 2020. Greenhouse gases such as CO2, CH4, and N2O are calculated and converted into CO2e. These inventory results are compiled and analyzed for each socio-economic region, helping to create a comprehensive picture of the greenhouse gas situation across the country.
The inventory is carried out based on available data, including spatial data on land use area and changes in forest land use. This helps ensure accuracy and transparency in assessing the levels of greenhouse gas emissions and removals.
When conducting the inventory, agencies must comply with IPCC guidelines while making appropriate adjustments to suit the specific characteristics and context of Vietnam.
The process of conducting a GHG inventory in forestry
Circular 23/2023/TT-BNNPTNT stipulates that the GHG inventory process must be carried out on a two-year cycle and follow specific steps. This process helps ensure the accuracy and completeness of the inventory results. The basic steps include:
- Selecting the GHG inventory method: Selecting the appropriate method is the first step, helping to determine how data will be collected and processed.
- Selecting emission factors: Emission factors must be chosen based on each type of greenhouse gas and the characteristics of each forestry area.
- Collecting and processing activity data: Data on forest area, harvesting activities, and damage caused by natural disasters must be collected from reliable sources and processed scientifically.
- Calculating greenhouse gas emissions and removals: The collected data is used to calculate the amount of greenhouse gases emitted and removed from forest areas and forest land.
- Quality control and quality assurance of the GHG inventory: The quality control process helps ensure the accuracy and transparency of the inventory results.
- Assessing the reliability of the GHG inventory results: The reliability of the results must be assessed to ensure that the data is not distorted.
- Recalculating the GHG inventory results of the previous inventory period: This helps identify the changes in greenhouse gas amounts across each inventory cycle.
- Preparing the GHG inventory results report: The report must be prepared in detail, fully reflecting the situation of greenhouse gas emissions and removals in the forestry and forest land sector.
- Appraising the GHG inventory results: The inventory results are appraised to ensure accuracy and completeness before being recognized.
Appraisal of the GHG inventory results
After conducting the GHG inventory, the results must be appraised to ensure accuracy and validity. The Forestry Department will organize a meeting of the Appraisal Council, comprising representatives from the Forest Protection Department, the Department of Science, Technology and Environment, and relevant experts. This Council is tasked with reviewing and reaching conclusions on the quality of the GHG inventory report.
The appraisal process must comply with the provisions of Circular No. 01/2022/TT-BTNMT of the Ministry of Natural Resources and Environment, while ensuring appropriate timing and content for the appraisal. After receiving feedback from the Appraisal Council, the lead unit will incorporate it and revise the report to finalize it and submit it to the Forestry Department. Finally, this report will be used as the basis for compiling the national GHG inventory report.
