Eco-Industrial Parks: Vietnam vs Thailand vs Indonesia — Green Standards

As global brands demand proof of carbon footprints from suppliers, the eco-industrial park has turned from concept into competitive advantage. Vietnam, Thailand and Indonesia are racing to build green standards for parks — but each defines green differently, and investors need to know which certification truly matters to their customers.

Vietnam: an eco-park legal framework taking shape

Vietnam has piloted the eco-industrial park model since 2015 with UNIDO support, and Decree 35/2022/ND-CP on industrial and economic zone management defines eco-park criteria (industrial symbiosis, cleaner production, resource efficiency). Parks such as Hiep Phuoc, Tra Noc and Deep C are implementing it. Under the Environmental Protection Law 72/2020/QH14 (effective 1 January 2022), park tenants must meet discharge standards and periodic monitoring — the mandatory foundation of any green standard.

Incentives for green projects in eco-parks include CIT incentives for clean technology plus green-transition programme support. The challenge: Vietnamese eco-park certification is less internationally recognised than global standards.

Thailand vs Indonesia: two approaches

Thailand leans on international certification: many parks hold ISO 14001, rooftop solar is promoted inside parks, and the IEAT (Industrial Estate Authority of Thailand) pursues carbon goals. Indonesia focuses on green industrial estates with centralised wastewater treatment requirements and is building a national carbon-credit framework.

All three require emissions reporting for the EU’s CBAM — and that is the real driver: not a wall certificate, but traceable carbon data for each shipment to Europe.

Choose a green park by ESG need

Brands needing ESG reporting for the EU market: prioritise parks with carbon metering, on-site renewables and CBAM advisory — Thailand currently leads on readiness. Projects needing low costs and willing to build green systems from scratch: Vietnam and Indonesia offer more headroom with larger land banks. The deciding criterion is not the eco label but the ability to supply credible environmental data.

Frequently Asked Questions

How does each country define eco-industrial parks, and which certification counts?

Vietnam: criteria in Decree 35/2022/ND-CP (industrial symbiosis, cleaner production). Thailand: ISO 14001 plus IEAT programmes tied to renewables. Indonesia: green estates with centralised wastewater treatment. For EU customers, traceable carbon data matters more than the certificate’s name.

What extra incentives exist for green projects in parks?

Vietnam: CIT incentives for clean technology and environmental equipment under Investment Law 143/2025/QH15 and tax law. Thailand: BOI top-ups for energy-saving and renewable projects. Indonesia: incentives within green estates under regional policy.

Renewable-energy and water-recycling requirements in green parks?

No country yet mandates 100% renewable energy in parks, but the trend favours rooftop solar and DPPA procurement. On water: all three require centralised wastewater treatment to standards before discharge; water recycling scores bonus points in eco-park standards.
