Toronto-listed software group Abaxx Technologies has approved global environmental markets exchange Climate Impact X ( CIX ) as an eligible custodian for its Singapore-based start-up Abaxx Exchange’s carbon futures contracts, which will allow participants taking delivery under these contracts to hold their credits with CIX, giving them an additional route to manage post-trade activity.

Environmental markets remain fragmented, the companies note, with carbon credits held across multiple registries. This can create operational complexity and added cost for companies moving assets between markets.

With CIX as an approved custodian, clients can leverage CIX’s omnibus custodial service and multi-registry connectivity to hold, transfer and retire credits delivered under Abaxx carbon futures, alongside credits from their own spot market activity. This provides greater flexibility, enhances trading efficiency and reduces the need to maintain multiple service provider accounts or relationships.

This arrangement covers Abaxx’s Jurisdictional REDD+ and Corsia Phase One futures contracts and forms part of CIX's ongoing efforts to build the market infrastructure needed to scale participation.

CIX is connected to 12 registries and counting, including the complete network of programmes fully approved by the International Civil Aviation Organisation ( ICAO ) for the first compliance phase under the Carbon Offsetting and Reduction Scheme for International Aviation ( Corsia ), a UN-backed market system to compensate for international aviation’s carbon footprint.

The arrangement was first used on July 1 to facilitate the transfer and delivery of 120 lots under Abaxx’s Corsia Phase One futures contract. Each lot represents 100 Corsia Eligible Emissions Units, equivalent to 100 tonnes of CO2 of verified emissions reductions or removals.

“We’re seeing a broader evolution in environmental markets towards the same connected infrastructure found in established financial markets, and this partnership with Abaxx is an important step in that direction,” says Ellery Sutanto, CIX’s chief commercial officer ( CCO ). “As these markets mature, a common infrastructure linking carbon futures and spot markets is key to unlocking deeper liquidity and more efficient price discovery. Giving participants a shared venue and greater choice in how they hold and manage credits will help channel capital more efficiently towards high-integrity climate solutions.”

Joe Raia, Abaxx Exchange’s CCO, adds: “Market participants need clearer ways to price carbon exposure before they trade, and more efficient ways to manage credits after they do. Abaxx carbon futures are designed to provide a transparent, exchange-traded price signal, and CIX’s approval as an eligible custodian expands the post-trade choices available to participants taking delivery under those contracts.”
