The Carbon Kilo Standard
A public blueprint for representing carbon as kilos and grams across registries, exchanges, and banks.
Built on W3C Verifiable Credentials and Arbitrum reference contracts, with on-chain encumbrance to prevent double-counting.
You're licensing the blueprint, not a platform.
An open standard developed by Ric Richardson
Patent-pending architecture
What are CarbonKilos?
CarbonKilos defines how carbon mass is represented, verified, encumbered, and retired across markets — ensuring units cannot be double-counted or double-sold.
CarbonKilos VC Schema
Identity, mass, origin, registry ID — standardized across all carbon credentials.
Encumbrance Model (A → E → R)
Available → Encumbered → Retired. Prevents double-counting at the protocol level.
On-chain Mirror Contract
Arbitrum blueprint that mirrors VC state — cannot mint beyond verified mass.
Human Scale
Kilos and grams instead of abstract tonnes.
Quality Rating Model
Moody's-style grades in VC and on-chain metadata.
Connect to existing carbon registries.
Built-in compliance checkpoints.
Standard events for tracking state changes.

A clean flow from registry issuance to on-chain state and retirement.

VC Schema
The CarbonKilos schema defines how carbon mass is represented in W3C Verifiable Credentials — a standardized format that works across registries and platforms.
Arbitrum Contract Blueprint
Contract mirrors VC state and cannot mint beyond verified mass.
Every state transition emits events for auditors. The contract enforces the encumbrance model at the protocol level.
Encumbrance
Encumbrance prevents double-spending of carbon mass, making carbon usable in real finance.
Encumbered kilos as collateral
Carbon mass serves as verifiable collateral for carbon-backed lending products.
Repo lines on verified mass
Repo agreements against verified mass with guaranteed non-double-countable carbon.
Structured products
Derivatives and structured products built on encumbered carbon with full auditability.
Designed For
CarbonKilos is built for the institutions shaping carbon market infrastructure.
