OTC Introduction Service · In development
Trade credits.
Directly.
An introduction service for premium carbon credits. We introduce verified sellers to buyers by type, vintage and price. Execution and settlement happen bilaterally, off-platform. Every listing tied to a registry serial number.
How it works
Two sides. One platform.
List your credits
Hold premium credits you want to sell instead of retire? List them on the board. Set your price, show your vintage and registry ID, let verified buyers find you.
Submit your listing
Credit type, vintage, volume, listed price per tonne, registry serial number.
ClimSen verifies
We cross-check your serial number against the registry. No unverified listings published.
Buyers find you
Your listing goes live. Interested buyers send a request. You negotiate terms directly.
