Verra VCS Gold Standard ACR CAR

Ground Truth
for Carbon Credits

Field-precision biological data meets digital ledger immutability. The most defensible MRV records in the voluntary carbon market.

Compatible with Verra VCS Gold Standard ACR CAR IPCC
The Platform

Everything a field verifier needs

From plot establishment to registry-ready reports, Silvaculture covers the full MRV workflow — offline-capable and cryptographically audit-ready.

Tree Mensuration

Record DBH, height, species, crown class, and decay data with standardized forestry protocols. iOS-native with offline sync.

Plot Management

Sub-meter GPS plot establishment with photo-tagging, permanent marker documentation, and nested subplot support for stratified sampling.

Carbon Calculations

IPCC-compliant allometric equations with species-specific biomass library. Above/below-ground carbon stocks with uncertainty bounds. VM0045 ready.

Immutable Audit Trail

SHA-256 hashing of all field photos, GPS waypoints, and measurement records. Every data point is cryptographically tamper-evident for third-party verifiers.

Offline-First Sync

Full data collection without connectivity. Automatic cloud sync when signal is restored. Multi-user accounts with role-based field team access.

AI-Powered Analysis

Risk scoring, carbon growth predictions, climate data integration, and AI-assisted species identification. 14 edge functions powering real-time insights.

The Workflow

From field to verified carbon credit

Silvaculture follows the complete MRV cycle required by major carbon registries — from first measurement to final audit report.

1

Establish Plot

Sub-meter GPS coordinates, photo-documented permanent markers, stratum assignment. Circular, rectangular, and nested subplot designs.

2

Collect Field Data

Species, DBH, height, crown class, decay class for every tree. Standardized protocols with offline data capture and photo documentation.

3

Calculate Carbon Stocks

Species-specific allometric equations compute live and dead biomass, converting to CO2e per hectare. Compliant with VM0045 and equivalent methodologies.

4

Monitor & Predict

Risk scoring, climate data integration, and AI-powered carbon growth projections. Sequestration trajectory charts track your offset portfolio over time.

5

Export for Verification

Registry-ready MRV reports with full audit trails, cryptographic integrity proofs, and structured exports for third-party verifiers. CSV, JSON, and PDF formats.
