| Greenhouse gases (GHGs) are gaseous constituents of the atmosphere, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). The unit used to measure greenhouse gases is carbon dioxide equivalent, abbreviated as CO2e. From 2024 onwards, businesses will carry out facility-level greenhouse gas inventories and prepare a facility-level greenhouse gas inventory report every 2 years, submitting it to the provincial People’s Committee before 31 March (from 2025). The provincial People’s Committee receives, reviews and consolidates the reports and sends them to the Ministry of Agriculture and Environment and the ministries managing the relevant sectors before 30 June (from 2025). In particular, for thermal power plants and iron and steel and cement production facilities, which prepare reports from the 2026 reporting period, and facilities allocated emission quotas for the period from 2027, which prepare reports from the 2028 reporting period, the report must be appraised by an appraisal unit before being sent to the Ministry of Agriculture and Environment. |
Businesses must be able to identify and manage the risks related to their GHG emissions to ensure long-term success in a competitive business environment and to comply properly with legal policies.
B. Legal regulations on greenhouse gas inventory for businesses (updated to 10/2026)
1. Law on Environmental Protection 2020 (Law No. 72/2020/QH14)
Since 1 January 2022, when the Law on Environmental Protection 2020 (Law No. 72/2020/QH14) took effect, businesses on the List of greenhouse gas emitting facilities have been required to carry out a greenhouse gas inventory. This Law has been amended and supplemented by Law No. 146/2025/QH15 (effective from 1 January 2026).
2. Decree No. 06/2022/ND-CP (as amended and supplemented by Decree No. 119/2025/ND-CP)
This is the document providing detailed guidance on the inventory and mitigation of greenhouse gas emissions, and it is the main legal basis for the inventory and the allocation of emission quotas. Under Article 6, a facility must carry out an inventory if it is on the List issued by the Prime Minister (proposed by the Ministry of Agriculture and Environment and updated once every 02 years) and has annual emissions of 3,000 tonnes of CO2 equivalent or more, or falls into one of the following cases:
- Thermal power plants and industrial production facilities with total annual energy consumption of 1,000 tonnes of oil equivalent (TOE) or more;
- Freight transport companies with total annual fuel consumption of 1,000 TOE or more;
- Commercial buildings with total annual energy consumption of 1,000 TOE or more;
- Solid waste treatment facilities with annual operating capacity of 65,000 tonnes or more.
Facility-level inventory reports are prepared once every 02 years (from the 2024 reporting period) and sent to the provincial People’s Committee before 31 March (from 2025). Thermal power plants and iron and steel and cement production facilities prepare reports from the 2026 reporting period; facilities allocated emission quotas for the period from 2027 prepare reports from the 2028 reporting period. Reports in this group must be appraised by an appraisal unit before being sent to the Ministry of Agriculture and Environment (before 1 December from 2027).
3. Under Circular No. 96/2020/TT-BTC
Section 2, Article 10 of Circular No. 96/2020/TT-BTC guiding information disclosure on the securities market, effective from 1 February 2021, covers reporting on greenhouse gas emissions in the Annual Report of public companies. The financial information in the annual report must be consistent with the audited annual financial statements”.
In addition, Section 6, Part II of Appendix IV sets out further reporting requirements, including:
- Total direct and indirect greenhouse gas (GHG) emissions
- Measures and initiatives to reduce greenhouse gas emissions.
