Scientific methodology.
The evidence chain from field survey to audit-ready documentation.
Ecological Baseline
Assessment
Ecological Baseline Assessment
Independent ecologist surveys are conducted before any intervention begins. This establishes the evidence baseline against which all future change is measured — without it, no claim can be made.
- Vegetation cover mapping and canopy structure analysis
- Species indicator protocols across flora, fauna, and herpetofauna transects
- Soil condition assessment and reference ecosystem comparison
Satellite
Monitoring
Satellite Monitoring
Continuous observation from the ESA Copernicus Sentinel-2 constellation provides independent verification of conditions on the ground. At 10‑metre resolution with a five-day revisit cycle, the satellite record is not a snapshot — it is a continuous log.
- NDVI, EVI, bare soil fraction, and moisture indices
- Historical archive from 2015 onwards enables pre-programme comparison
- Automated disturbance detection: fire, encroachment, and clearing events
Additionality
Framework
Additionality Framework
Additionality is the core question of any impact claim: would this outcome have occurred without the intervention? We demonstrate additionality across four independent tests.
- Reference site comparison against matched control areas without intervention
- Historical land-use trajectory analysis to establish the counterfactual
- Legal protection status check — land must not already be protected under conservation schemes that would operate regardless of the programme
- Financial additionality: the intervention would not have occurred without credit revenue
Five-Year Outcome
Assessment
Five-Year Outcome Assessment
At years five and ten of the programme, an independent ecologist returns to repeat the baseline survey in full. This is not a desk exercise — it is the same field work, at the same reference points, by a party with no financial interest in the result.
- Vegetation cover change and canopy density increase
- Species indicator richness delta against baseline
- Bare-soil reduction and landscape connectivity index
Independent
Verification
Independent Verification
Evidence packages are structured for ISAE 3000 limited or reasonable assurance engagement. The standard was chosen because it is auditor-native: reviewers know it, know its limits, and know what an absence means.
- Ecological baseline report with GPS coordinates and legal land records
- Full satellite monitoring record for the programme period
- Additionality analysis and five-year outcome comparison
Evidence packages are compatible with Big 4 sustainability assurance practices and specialist ecology firms.
