Decarbonization has a paperwork department, and in Vietnam it is hiring. From September 25, 2026, a total of 2,441 facilities across six sectors must conduct greenhouse gas inventories under an updated official list. At the same time, a new decision on green projects makes documented ESG performance the entry ticket to state backed interest support. The explainer below follows the money and the spreadsheets: who must count, what counts as green, and why the people who can prove a number are becoming as important as the people who cut it.
Step one: the inventory list grows up
Prime Ministerial Decision 42 of 2026, issued in August 2026, updated the list of sectors and facilities subject to mandatory greenhouse gas inventories. VnEconomy reported the count rising from 1,912 facilities in 2022 to 2,166 in 2024 and now 2,441 in 2026, an increase of 529 facilities in four years. The industry and trade sector dominates with 1,916 facilities, nearly 80 percent of the total, and manufacturing and processing alone accounts for 1,792 of them. Construction contributes 411 facilities, transport 53, and agriculture and environment 61.
The qualifying thresholds still follow Decree 06 from 2022. In broad terms, a facility enters the system if it emits at least 3,000 tonnes of carbon dioxide equivalent a year, or uses at least 1,000 tonnes of oil equivalent of energy a year, with a separate capacity test for large solid waste facilities. An inventory is not a press release. It requires a facility to identify emission sources, apply accepted factors, keep records, and produce a report that a ministry or provincial authority can review.
Step two: green gets a definition with teeth
For years, Vietnamese companies used the word green without a single national test. Decision 46 of 2026, signed on September 17, 2026 and effective from November 1, 2026, supplies that test for projects seeking official recognition and support. VnEconomy reported that a project is classified as green when it belongs to a designated sector, matches the sustainability objective for that category, and meets the specific statutory requirements attached to it. The framework lists 45 green project types across seven sectors, including 10 energy sub sectors, and 19 circular economy project types.
The detail is practical. Solar projects must meet efficiency and equipment certification standards and producer responsibility for recycling. Green buildings need accredited certificates and low impact refrigerants. Transport eligibility covers low or zero emission fleets and charging infrastructure. Independent assessment bodies verify green or circular status, and project owners must compile and submit ESG compliance reports. Recognition is therefore no longer a label a company prints for itself; it is a file that someone else checks.
Step three: ESG performance becomes a price
The reason many firms will care is money. Under the policy that Decision 46 guides, projects that meet green or circular criteria and apply the ESG framework can qualify for state interest support of 2 percent a year, a link SGGP described in April 2026 as the first time state budget interest support in Vietnam has been tied directly to green criteria. The ESG framework contains 52 criteria across the environmental, social and governance pillars. Large enterprises must meet at least 40 of them; smaller enterprises and household businesses face lower thresholds scaled to their size. Borrowers must maintain compliance through the support period, and banks use the assessment when deciding loans and subsidies.
Two percent a year is not a slogan. On a large factory loan it can outweigh the cost of the consultants, meters and audits needed to document performance, which is exactly the incentive design: the state pays for verified behavior, not for intentions.
Step four: listed company disclosure tightens around it
A parallel track covers public companies. Vietnam’s disclosure rules for public and listed companies already require environmental and social information in annual reporting, and the 2026 Corporate Governance Code, launched in February 2026, pushes boards to oversee ESG and climate risk, consider dedicated ESG committees, and move toward independently verified sustainability disclosure under a comply or explain approach, initially for listed companies. Governance reporting may sound softer than a facility inventory, but investors read both. A listed manufacturer can now face three connected audiences for the same data: the inventory authority, the bank assessing a green loan, and shareholders reading the annual report.
What this means in practice
For a facility manager, the work sequence is now clear. Confirm whether the site is on the 2,441 facility list. Build the inventory from energy bills, fuel records and process data, not from estimates drafted at year end. Map any planned investment against the Decision 46 categories before applying for support, because retrofitting a claim after spending is far harder. Assign ownership: one team for data, one for verification readiness, and board level review for anything published.
The accountants of decarbonization will not appear in ribbon cutting photos. Their product is a defensible number, produced on time, that a verifier, a bank and a regulator all accept. In a market where a carbon exchange has begun trading and export customers audit supply chains, that product is quickly becoming a condition of doing business. ESG reporting in Vietnam is no longer a voluntary story told after the year ends. It is a mandatory count, with a growing list of names on it.
