Marine & Terrestrial EIA Project Vietnam

Project Overview

The Vinfast e-Scooter and Car Manufacturing Plant is located within the Dinh Vu – Cat Hai Economic Zone (DVCHEZ), on Cat Hai Island, Hai Phong City, Vietnam. The site covers an area of approximately 335 hectares (ha), of which approximately 135 ha is on land reclaimed from the sea. The site is located within the 21,600 ha Dinh Vu-Cat Hai Economic Zone (DVCHEZ) situated on the at the mouth of the Cam River in the Bach Dang-Cam Estuary, Eastern Vietnam. An independent environmental and social due diligence assessment identified that the impacts of habitat loss due to vegetation clearing were not undertaken in accordance with the International Finance Corporation (IFC) PS6 requirements. A comprehensive assessment of the natural habitat or determination of requirements for biodiversity offsets was not adequately completed.  Based upon previous studies the project site contains relatively poor terrestrial biodiversity.

Our Role

Ecobalance was engaged to identify a number of Valued Ecosystem Components (VECs) that were at risk from impacts originating from construction or operational activities at the Vinfast Development Site (VDS), including: 

  • Deterioration in marine water quality of coastal waters off Cat Hai island as a result of runoff and/or pollutant releases from the VDS;
  • Loss of 13 ha of seagrass habitat from land reclamation activities to the south of the VDS;
  • Loss of 180 ha of terrestrial CH for the Black-faced Spoonbill on Cat Hai Island within the terrestrial boundary of the VDS;
  • Potential loss or degredation of near shore CH for 3 species of fish listed nationally as threatened; and 13 species of fish described as endemic or having restricted range within the boundary of the reclamation area; 
  • Impacts from dredging of the estuary south of Cat Hai Island to provide fill for reclamation site (to be confirmed); and
  • Contribution to cumulative impacts.


Appropriate mitigation measures were developed for a number of these impacts; however, others require additional field studies to be implemented before the full extent of the impact can be fully understood.

An Environmental Risk Assessment found that losses of Critical Habitat (CH) for the Black-faced Spoonbill cannot be mitigated to non-significant levels and an offset strategy should be developed. Offsets must also be made for the losses of Seagrass habitat, which will reduce the impacts to this non-CH to non-significant levels. Additional assessment and studies were also identified to be required to fully understand the potential impacts the VDS poses to CH for fish species, impacts from historic dredging activities and the contribution of the construction and operational works on the VDS to cumulative impacts.
