The environmental impact assessment (EIA) is the procedure many FDI factories discover they need at the worst possible moment: when design is finished, the contractor is chosen and the construction start date is announced. Understanding the EIA as a milestone inside the investment sequence — not a paper to request at the end — is what separates an on-schedule project from one a quarter late.
1. Which projects must do an EIA
Under Article 30 of the Law on Environmental Protection 72/2020/QH14, EIA subjects are group I investment projects — those with high risk of adverse environmental impact by criteria of production type, scale, capacity and sensitivity of the receiving area (residential zones, water sources, conservation areas, heritage) — detailed in Decree 08/2022/ND-CP. A manufacturing plant generating industrial wastewater, emissions or hazardous waste at material scale, or sited near a sensitive area, almost always falls into this group. Group II and III projects follow lighter procedures (environmental permit or environmental registration), so classifying the project against the Decree 08/2022 lists is the first legal step to make solid, before any detailed design.
2. Where the EIA sits in the investment sequence
The EIA is performed during project preparation, in parallel with the feasibility study, and the EIA appraisal result is a basis for the investment policy decision, the investment decision and subsequent construction permits. This sequence carries an important design consequence: environmental protection solutions (wastewater and emissions treatment technology, site layout with buffer zones) must be fixed in enough detail to be written into the EIA report, and the approved EIA report becomes a legal commitment of the project — changing production technology in ways that alter environmental impact can force a re-assessment or re-report under the rules. An investor who changes plant design after EIA approval without re-checking EIA commitments creates the classic trigger for adjustment demands at the environmental permit stage.
3. The appraisal and approval process
The main steps are: the project owner prepares the EIA report (usually through a capable consultancy) covering baseline environment, impact forecasts and mitigation measures, and an environmental management and monitoring programme; consultation of directly affected residential communities and stakeholders as prescribed; submission to the competent appraisal authority (the Ministry of Agriculture and Environment for centrally-governed projects, the provincial people committee for local ones — under current decentralisation); an appraisal council meeting, with the owner refining the report per appraisal opinions; and the authority decision approving the EIA result. In practice, the number of post-appraisal refinement rounds is the largest time variable, depending on first-draft quality and site sensitivity.
4. Costs and the errors that delay projects
EIA costs include report consultancy, baseline monitoring and appraisal fees — small against total investment, while time is the real cost. Three classic delay errors are: choosing a consultancy without experience in similar production types, so the report is returned for many rounds; skipping or formalising community consultation, letting resident complaints surface at the appraisal stage; and writing environmental commitments beyond the plant real operating capability (over-ambitious treatment parameters) — those commitments return at the environmental permit and operation stage as legal obligations, not decorative text.
5. Conclusion for investors
An EIA for an FDI factory should be managed as a project-schedule workstream on par with design and construction permitting: classify the project correctly from the start, lock environmental treatment technology early, consult the community genuinely, and write commitments at a level the plant can actually operate. With those four things done, the EIA is a predictable procedure; done in reverse, it becomes the reason an FDI project slips with nobody specifically responsible.
Frequently Asked Questions
Which projects must do an EIA?
Group I investment projects under Article 30 of the Law on Environmental Protection 72/2020/QH14 and the lists in Decree 08/2022/ND-CP: high adverse-impact risk by type, scale, capacity and area sensitivity. A plant with material wastewater, emissions or hazardous waste, or near a sensitive area, almost always falls in this group.
How many steps does an EIA take?
The main steps: prepare the EIA report, consult affected communities, submit to the competent authority, an appraisal council meeting and opinions, the owner refines the report, and the authority decision approving the EIA result. The EIA runs in project preparation, before investment decisions and construction permits.
How long does it take?
Timing depends mainly on the number of post-appraisal refinement rounds, first-draft quality and site sensitivity. Choosing a consultancy experienced in the same production type and doing community consultation genuinely are the two biggest accelerators.
What does it cost?
Costs include report consultancy, baseline monitoring and appraisal fees — small against total investment. The real EIA cost is time: a project delayed by many returned report rounds, or commitments written beyond operating capability, pays at the environmental permit stage.
