VT0001 additionality explained: the Verra AFOLU tool steps, from land-use alternatives to investment, barrier and common practice tests, with Indonesian cases.

VT0001 is Verra’s tool for demonstrating and assessing additionality in agriculture, forestry and other land use (AFOLU) projects under the VCS. It gives a stepwise test to show that the project would not have happened without carbon finance: identify realistic land-use alternatives, then prove the project is not the most attractive or is blocked by barriers, then show it is not common practice.

Many AFOLU methodologies refer to VT0001, though newer methodologies increasingly build additionality into standardised approaches. Read additionality for the broader concept.

The steps of VT0001

Step 1: Identify alternative land-use scenarios

List credible alternatives to the project on the same land. For a reforestation project on degraded farmland in Indonesia, alternatives might include:

• continued cassava or maize cropping;
• conversion to oil palm or other plantation crops;
• planting a timber crop without carbon finance;
• the project itself without carbon revenue.

Each alternative must comply with laws and regulations, unless those laws are systematically not enforced, which must then be evidenced. This is where regulatory surplus enters. If the law requires the activity, the project is not additional.

Step 2: Investment analysis

Show that the project is less financially attractive than at least one alternative, or not financially viable without carbon revenue. Options include:

• simple cost analysis, where the project earns no income other than carbon;
• investment comparison, comparing financial indicators across alternatives;
• benchmark analysis, comparing the project’s internal rate of return with a relevant benchmark rate.

Use realistic, documented inputs and run sensitivity analysis. Verifiers test whether reasonable changes in costs or prices would make the project viable without carbon finance.

Step 3: Barrier analysis

As an alternative or complement, show that real barriers prevent the project without carbon finance. Typical barriers include lack of access to finance, technical capacity, seedling supply, land tenure complications or ecological constraints. Each barrier must be specific, documented and shown not to block at least one alternative.

Step 4: Common practice analysis

Show that similar activities are not already widespread in the region without carbon finance. If they are, explain the essential differences between the project and those activities.

How to apply VT0001 step by step

1. Read the methodology to confirm it calls VT0001 and which version.
2. Define the geographical area for alternatives and common practice.
3. Gather data: land-use maps, farm budgets, timber and commodity prices, interest rates.
4. Build a transparent financial model for the project and each alternative.
5. Document barriers with third-party evidence: bank letters, government statistics, studies.
6. Survey the region for comparable projects.
7. Write the additionality section of the project description with every source referenced. See project design documents.

Indonesia application

Indonesian specifics that verifiers look at:

• Regulatory obligations. Holders of certain forest-area use permits must carry out watershed rehabilitation. Concessions may carry restoration duties. Peat protection rules require restoration on some land. Activities already required are not additional.
• Oil palm as an alternative. On many lowland sites oil palm is a realistic, profitable alternative. That supports additionality for forest restoration, but the legality of conversion must be checked.
• Government planting programmes. Large national planting campaigns exist. If the project replicates them without distinct features, common practice fails.
• Timber plantations. Fast-growing sengon or jabon can be profitable without carbon revenue on good sites. Investment analysis must show why carbon changes the decision.

Pitfalls verifiers flag

• Investment analysis built on optimistic or undocumented inputs.
• Benchmarks that do not fit the project developer or sector.
• Generic barriers with no project-specific evidence.
• Common practice area drawn to exclude similar projects.
• No evidence that carbon finance was considered before the project started.

Building a financial model verifiers accept

Use local costs for seedlings, labour, maintenance and transport, backed by quotes or invoices. Use realistic timber and crop prices from published sources. Choose a discount rate or benchmark that fits the developer, and explain it. Show the model in a working spreadsheet, not only as a summary table.

Run sensitivity tests on the inputs that matter most, such as timber price, yield and discount rate, and report the results in the project description.

VT0001 and newer approaches

Performance benchmarks are replacing project-by-project tests in some methodologies. VM0047 uses a dynamic performance benchmark in its area-based approach. That makes baseline setting and additionality one calculation. Check which approach applies before you start. Our PDD development service builds additionality cases, and the ARR feasibility guide covers early screening. See the standards hub for more.
