What We Do

Carbon Offset Desk

Carbon credit procurement for buyers

A buy-side procurement platform where companies purchase carbon credits online from one of Japan's largest inventories — J-Credits, JCM credits, and GX-ETS allowances. Only credits and allowances recorded in official public registries are listed. We handle purchase, retirement (cancellation) on the registry, and retirement reporting end to end, with transparency on price and available volume.

J-Credit Buyback Center

Direct purchase of J-Credits

Our direct purchase desk for J-Credit holders. We post indicative bid prices at all times, contract electronically, and pay within 30 days of confirming the registry transfer. Cumulative direct purchases of approximately ¥200 million (30,000 t-CO₂) give us a steady, first-hand flow of issued credits — the origination base for our sell-side inventory.

OTC Hub

OTC trading platform for intermediaries

A trading platform for carbon credit intermediaries that aggregates bids and offers for over-the-counter J-Credit transactions in one place. Carbonlink acts as the counterparty, handling matching through transfer execution, so intermediaries can trade while keeping their end-client relationships confidential. Free to use, with email verification and business checks on sign-up.
