akar.earthBiodiversity Credit Methods Compared
Biodiversity credit methodologies compared: Plan Vivo PV Nature, Verra's Nature Framework and other approaches, what each measures and Indonesian fit.
Biodiversity credit methods differ mainly in what they measure: some score habitat condition by area, some track species or ecological indicators, and some combine both with community governance. There is no common unit equivalent to a tonne of CO2, so you must choose a method whose metric matches your site, your monitoring budget and what your buyers want to claim.
The market is young. For Indonesian projects, the practical choice today is usually between established certifiers that already run carbon programmes, such as Plan Vivo and Verra, and newer specialised methodologies. Many developers add a biodiversity unit to an existing carbon or restoration project rather than building one from scratch.
Main approaches compared
| Approach | What is measured | Strengths | Watch-outs |
|---|---|---|---|
| Plan Vivo PV Nature | Biodiversity outcomes for locally led conservation and restoration, using a certificate calculation protocol | Strong community governance and benefit sharing; same organisation as PV Climate | Detailed requirements sit in the protocol documents, so read them in full |
| Verra Nature Framework | Biodiversity gains and avoided losses against defined metrics | Large registry and buyer familiarity through VCS | Newer framework; check current version and project uptake |
| Habitat condition x area metrics | Hectares weighted by habitat condition score | Simple, scalable with remote sensing | May miss species-level outcomes |
| Species-based metrics | Presence, abundance or occupancy of indicator species | Close to what people mean by biodiversity | Costly monitoring, high variance |
| Composite indices | Several indicators combined | Captures more dimensions | Harder to audit and compare |
| Co-benefit labels such as CCB | Biodiversity benefits attached to carbon credits | Widely recognised | Not a separate biodiversity unit |
Step-by-step: choosing a method
- Define the claim. Will buyers say they funded restoration, protection or a measured gain? The claim shapes the metric.
- Check the ecology. A peat swamp forest in Central Kalimantan, a karst forest in Sulawesi and a mangrove in North Sumatra need different indicators.
- Assess monitoring capacity. Species-based methods need surveys, camera traps, acoustics or eDNA. Condition metrics need field calibration of satellite products.
- Check stacking rules if you also issue carbon credits. See biodiversity vs carbon credits.
- Confirm safeguards and community rules. Most methods require consent, benefit sharing and grievance mechanisms.
- Review buyer guidance. Industry principles, including those from international advisory groups, discourage using credits to offset damage elsewhere.
- Pilot the monitoring on a few plots before committing to a method.
Baselines and additionality
Biodiversity credits face the same core questions as carbon: what would happen without the project, and is the gain real and lasting? Baselines might be habitat loss trends, reference sites, or a counterfactual based on drivers of deforestation. Permanence is often handled through long project terms and legal protection rather than buffer pools.
Indonesia specifics
Indonesia is megadiverse, with high endemism in Sulawesi, Maluku and Papua. Many high-value sites already carry legal designations or overlap with HCV areas, so additionality must be argued carefully. Community and customary rights matter as much as for carbon, and biodiversity monitoring often depends on local knowledge for species identification.
What drives value
Buyer interest is linked to nature disclosure frameworks such as TNFD and to supply-chain commitments. Credits backed by transparent monitoring, clear community benefits and an established certifier tend to be easier to sell. Market depth and prices are still thin, so do not build a project budget that depends on biodiversity revenue alone.
Questions to put to any methodology
Before committing, ask the standard or methodology owner, and read the documents to check:
- What exactly does one credit represent: an area, a condition score, a species outcome, or a period of protection?
- How is the baseline set, and how often is it revisited?
- What field evidence is required, and how often?
- How are reversals handled, for example after fire or encroachment?
- What share of revenue must go to communities, and how is that verified?
- Can the credit be combined with carbon credits from the same area, and under what conditions?
- Who validates and verifies, and are they independent?
- What claims are buyers permitted to make?
Clear answers to these questions are a good proxy for how well a method will hold up as the market matures. Vague answers are a warning sign.
Common mistakes
- Choosing a metric that sounds impressive but cannot be monitored on your budget.
- Selling biodiversity and carbon units that claim the same outcome.
- Ignoring existing legal protection when arguing additionality.
- Using species lists without effort-standardised surveys, which makes change impossible to detect.
- Promising biodiversity revenue to communities before a buyer exists.

Frequently asked questions
What is a biodiversity credit?
A biodiversity credit is a certified unit representing a measured, positive change or protected state of biodiversity at a specific site over a defined period. Unlike carbon credits, there is no single common unit like a tonne of CO2.
Which biodiversity credit standards exist?
Established options include Plan Vivo's PV Nature and Verra's Nature Framework, alongside several newer private methodologies and national schemes. Each uses a different metric, so credits are not interchangeable.
Can a project sell both carbon and biodiversity credits?
Some standards allow it, if the claims are distinct and each unit is backed by its own monitoring. Check the rules on stacking and avoid selling the same outcome twice.
Are biodiversity credits used for offsetting?
Most voluntary frameworks discourage using them to offset harm elsewhere, and frame purchases as contributions to nature. Compliance schemes such as habitat banking work differently.
