ZerraLedger — The Trusted Ledger for a Net-Zero World

A digital book-and-claim registry providing the auditable backbone for SAF certification and low-carbon fuel traceability.

Our Mission: From SAF Certification to a Global Low-Carbon Fuels Marketplace

The Problem

Manual and fragmented Sustainable Aviation Fuel (SAF) certification creates significant challenges for the industry:

  • Risk of double counting and lost carbon value.
  • Inconsistent compliance with GoO (Guarantees of Origin) and LCLF (Low Carbon Liquid Fuels) standards.
  • Lack of auditable chain-of-custody for airlines and producers.

Regulatory mandates are accelerating, but the necessary infrastructure to support transparent and scalable SAF certification lags behind.

Our Solution: Transparent, Scalable SAF Certification

ZerraLedger is a lightweight, API-first ledger platform designed to be the auditable backbone for SAF certification:

  • Tracks chain-of-custody: Feedstock → Fuel → Flight.
  • Generates GoO/LCLF-compliant certificates with AI-powered verification.
  • Supports both physical and Book & Claim models with immutable records.
  • Offers a lightweight, API-first integration for producers and airlines.

SAF is our beachhead; the same platform scales to the full APAC Low Carbon Liquid Fuels market.

Why ZerraLedger Stands Out

Australia-Native Compliance

Built specifically for GoO and LCLF compliance within the Australian and APAC market context.

AI-Powered Verification

Automated verification, anomaly detection, and dynamic certificate generation for accuracy.

Lightweight & API-First

Designed for easy integration with existing producer and airline systems, minimizing disruption.

Immutable Records

Supports both physical and Book & Claim models with tamper-proof, immutable records.

Full Chain-of-Custody

Provides end-to-end traceability from feedstock to fuel to flight.

Scalable to APAC LCLF

While SAF is our beachhead, the platform is built to scale across the entire APAC LCLF market.
