Biodiversity Credit Readiness (Marine)
Biodiversity credit readiness requires more than metrics. You need a defensible chain from baseline surveys to repeat monitoring, clear outcome types, and conservative claims. MariMap keeps field evidence, QA/QC notes, and metrics together so reviewers can follow the full trail.
At a glance
- Define outcome type: uplift, avoided loss, or maintenance credits.
- Record additionality, durability mechanisms, and leakage risk.
- Separate inputs and activities from verified outcomes.
- Keep baselines and repeat surveys comparable across seasons.
- Package evidence with metrics definitions and sources.
Baselines and repeat surveys
- Mark a baseline survey and lock the sampling geometry.
- Schedule repeat surveys on the same plots or transects.
- Review QA/QC before exporting indicators.
Claims discipline
- Inputs and activities can be reported as implementation evidence.
- Verified outcome claims require independent verification and should reference the claim stage.
- Maintenance credits must show continued condition, not just activity.
Evidence pack checklist
- MRV summary with baseline flag and survey dates.
- Biodiversity indicators and habitat context.
- Methods, metadata, and provenance notes.
- References to the Metrics Reference and Data Providers.
MRV readiness and disclosure alignment
- Baseline vs repeat surveys: mark baselines and keep repeat surveys on comparable geometry.
- Monitoring plan logic: define cadence, QA/QC thresholds, and conservative handling of uncertainty.
- Outcome types and claims discipline: record uplift, avoided loss, or maintenance credits; separate inputs from verified outcomes.
- Rights and integrity: document FPIC, customary marine tenure, OECM, ICCA, benefit sharing, durability mechanisms, and leakage risk.
- Disclosure alignment: map indicators to TNFD, CSRD, ESRS, EU Taxonomy, SBTN, and SBTi requirements.
- Use the Metrics Reference and Data Providers for definitions and sources.
