According to Ledger Insights, the blockchain carbon credit trading platform AirCarbon Exchange (ACX) announced that it has completed a US$15 million Series B financing through convertible bonds, led by Singapore-based TRIREC, with participation from Banpu Public Company and Mubadala Investment Company PJSC. The investment brings the total funds raised to $25 million, including an investment in March as part of a strategic partnership with Deutsche Börse-owned European Energy Exchange (EEX). Based on the Polygon blockchain, AirCarbon started in Singapore and initially focused on CORSIA tokens to support carbon offsets in the aviation industry. Its products have since expanded to a series of tokens, including nature-based projects such as forests, renewable energy tokens, carbon Capture credit and more.
