Biodiversity Credit Readiness (Marine)
Use MariMap to document baselines, repeat surveys, and evidence packages aligned to biodiversity credit guidance. This guide outlines outcome types, additionality, durability, leakage, and claims discipline so evidence is audit-ready.
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.
