Diamond Standard™ Credit Registry
A verified marketplace for genuinely additional environmental credits — carbon, biochar, water, and biodiversity.
◆ THE DIAMOND STANDARD™ — ONE PRINCIPLE. NON-NEGOTIABLE.
We only originate and sell credits that represent genuinely new carbon sequestration or emissions reduction — carbon that would not have been removed from the atmosphere without direct human intervention. We never credit existing forests, natural ecosystems, or processes that occur without our intervention. Every credit in this registry was created by us, not discovered.
■ TRADING STATUS: Registry is in pre-launch phase. Credit registration is active. Live trading opens on first credit issuance — targeted Q1 2027. Forward purchase enquiries accepted now.

Why Diamond Standard Credits?
◆ BOARD-DEFENSIBLE
Every Diamond Standard credit can be defended to your board, your institutional shareholders, and a regulator. No REDD+ failures. No avoided deforestation accounting. Only what we physically created.
◆ EUDR COMPLIANT
All MarillionEx African operations produce full EU Deforestation Regulation compliance documentation for covered commodities including tobacco, cocoa, and palm oil.
◆ ZERO GREENWASHING EXPOSURE
By construction, not by audit — the Diamond Standard excludes existing forest credits before a project begins. The 2023 carbon market scandal cannot happen here.
