Introduction
A GHG inventory is not just a legal requirement, but an important strategic step that helps businesses identify and set out an emission-reduction roadmap.
A GHG inventory is the activity of collecting information and data on greenhouse gas emission sources, calculating greenhouse gas emissions and removals within a defined scope and for a specific year, following the methods and procedures issued by the competent authority (under Decree No. 06/2022/NĐ-CP).
Our GHG inventory service supports businesses throughout the entire process: defining the scope of operations, collecting data, calculating emissions, and preparing the GHG inventory report, thereby providing an emission-reduction roadmap that fits the business.
Why you need a GHG inventory?
Under Decree
06/2022/NĐ-CP
On the regulation of greenhouse gas emission mitigation and ozone layer protection
equivalent or more is the annual emission level for facilities.
equivalent or more is the annual emission level for facilities.
equivalent (TOE) is the total annual fuel consumption of thermal power plants, technology manufacturing facilities, transportation businesses and commercial buildings.
Under Decision
42/2026/QĐ-TTg
Sectors and greenhouse gas emitting facilities that must conduct a GHG inventory
in Vietnam must carry out a GHG inventory under Decision 42/2026/QĐ-TTg on the list of sectors and emitting facilities required to conduct a GHG inventory (effective 25/9/2026, replacing Decision 13/2024/QĐ-TTg).
thermal power, iron & steel and cement facilities received emission allowances for the 2025–2026 pilot (total cap under Decision 263/QD-TTg, allocated per facility by Decision 699/QD-BNNMT): inventory data decides whether a facility has a surplus or a shortfall.
Is your facility among the 2,441 facilities required to conduct a GHG inventory?
Under Circular No.
96/2020/TT-BTC
On guidance for information disclosure on the securities market
Listed companies must provide information on their greenhouse gas emissions together with their emission-reduction initiatives in the annual report submitted to the Ministry of Finance.

GHG inventory implementation roadmap
Under Decree 06/2022/NĐ-CP
Submit the next facility-level GHG inventory report (2025 and 2026 data) to the provincial People's Committee. Every 2 years, before 31/3 (Decree 06/2022 as amended by Decree 119/2025).
From 2027, every year before 31/3: submit the facility-level emission-reduction report for the previous year to the provincial People's Committee.
The pilot ends (through 2028); the domestic carbon market starts official operation with allowance auctions.
Prepare an Environmental and Social Impact Assessment Report, which consolidates direct and indirect greenhouse gas emissions along with emission-reduction solutions and initiatives, integrated into the annual report.
