Beyond power sales, renewable projects can generate a second revenue stream: carbon credits from avoided greenhouse-gas emissions. Vietnam is building its carbon market under Decree 06/2022/ND-CP — and renewables are the project group with the largest credit potential. But turning credits into cash is less simple than many assume.
What carbon credits are and how power projects create them
A carbon credit certifies one tonne of CO2-equivalent emissions reduced (or removed). Solar and wind projects displace fossil-fuel power — this avoided emission, once measured and validated under a recognised methodology, can become carbon credits sold to organisations needing offsets.
The threshold condition: additionality — the project would not have proceeded (or been financially viable) without carbon-credit revenue. Projects that enjoyed high preferential FIT tariffs may struggle to prove additionality — the technical point where many Vietnamese projects fail at registration.
Registration and verification: 4 steps
One, prepare the project design document (PDD) under the chosen carbon standard’s methodology (VCS, Gold Standard or the domestic mechanism when the market operates). Two, independent validation by an accredited body. Three, register with the standard’s administrator. Four, periodic monitoring, reporting and verification before credit issuance.
Costs are significant: PDD consultancy, validation fees, registration and periodic verification — small projects may not cover costs. In practice, many bundle into programmes (PoA) to share costs.
Selling credits: which market, what price
Today, Vietnamese project credits sell mainly on the international voluntary carbon market — prices swing widely by credit type, standard and project quality, from a few to tens of US dollars per credit (market reference, highly volatile). When the domestic carbon market fully operates (exchange, quotas), projects gain a domestic sales channel.
Legal note: carbon-credit ownership (project owner, shared with financiers, or the State under some mechanisms) must be defined in contracts — ownership disputes have occurred at many projects, wiping out carbon revenue. Don’t wait until issuance to ask who owns the credits.

Frequently Asked Questions
Can solar and wind projects generate carbon credits?
Yes. Renewables displace fossil-fuel power — the avoided emissions, once measured and validated under recognised methodologies, become saleable carbon credits. The hardest condition is proving additionality; projects that enjoyed high FIT tariffs may struggle here.
What are the carbon-credit registration steps?
Four steps: prepare the PDD under a carbon standard's methodology (VCS, Gold Standard or the domestic mechanism); independent validation; registration with the standard's administrator; periodic monitoring, reporting and verification before issuance. Costs are significant, so small projects often bundle into PoAs.
Where are carbon credits sold, and at what price?
Mainly on the international voluntary carbon market — prices swing widely by type and standard, from a few to tens of US dollars per credit (reference, highly volatile). Credit ownership must be contractually defined upfront to avoid disputes.
