Non-speculative carbon offset protocol

Overview

Fixing the broken carbon market

The voluntary carbon market — estimated at over $2 billion annually — is structurally broken. Offset credits are routinely sold to multiple buyers, projects are abandoned after the carbon has been counted, and no single global ledger exists to verify whether a given tonne of CO2 has genuinely been addressed. Existing registries are private, proprietary, and incompatible. None are permanent. None are publicly owned.

CarbonLedger is the Kardashev Institute's response to these failures. It is a non-speculative digital token protocol designed to create a permanent, transparent, tamper-proof public ledger of global carbon emissions and their verified offsets. One token — the CarbonLedger Token (CLT) — is issued for every metric tonne of CO2-equivalent ever emitted by humanity since records began, based on data published by the UNFCCC.

The protocol is fundamentally non-speculative by design. When an individual, organisation, or government offsets their footprint, they purchase a CLT and that token is permanently linked to a specific, verified offsetting activity. The token has no resale profit value — the economic model places all value in the act of transfer, via a transaction fee that flows entirely back to the CarbonLedger Trust to fund further verified repair.

Governance of the protocol is anchored in a permanent international legal structure based in Liechtenstein — rated the world's number one philanthropy jurisdiction — with regional operational entities across the UK, Europe, the Middle East, Asia, and the Americas. Each regional entity is constitutionally subordinate to the Liechtenstein hub, which owns all offset assets in perpetuity and cannot be dissolved, sold, or redirected. The protocol will be published as a standalone instrument once the first implementation cohort is confirmed.
