ARR Technical Audit Services

We provide independent ARR technical audits that translate scientific uncertainty into contract-ready decisions.

Service

Geospatial Analysis

Spatial QA, baseline verification, and risk overlays that validate boundaries and claims.

We test land-use history, control areas, and boundary integrity so baseline claims stand up at validation and future verification cycles.

Explore the toolkit for a focused set of evidence workflows and QA checks. Geospatial & MRV Toolkit.

  • Boundary and activity data QA
  • Leakage pathway diagnostics
  • Disturbance overlays and verification checks

Ground Truth Validation

Evidence audits that verify inventory design, field QA/QC, and data traceability.

We focus on whether field data and procedures are auditable, repeatable, and defensible when questioned by validators or buyers.

  • Plot design and sampling verification
  • Data lineage from field to issuance
  • Audit readiness for validation and verification
Service

Carbon Projections and Accounting

Conservative, evidence-backed projections that quantify uncertainty and align accounting with ARR methodology rules.

We stress-test growth, survival, and baseline assumptions so credit estimates remain credible under performance benchmarks and monitoring reviews.

  • Growth and survival assumptions anchored to field evidence.
  • Uncertainty tracking with clear sensitivity bounds.
  • Accounting logic mapped to crediting and buffer rules.

Methodology

VM0047 Due Diligence Framework

A repeatable review sequence that makes assumptions explicit and auditable.

  1. 1. Evidence intake and claims mapping
  2. 2. Baseline and additionality stress-tests
  3. 3. MRV design review and uncertainty checks
  4. 4. Leakage, permanence, and reversal risk
  5. 5. Decision-ready report, risk register, and buyer protections
