Voluntary carbon markets are opaque as they are dominated by OTC deals resulting in hefty brokerage fees and hidden margins. Matchmaking, integrity and settlement issues as well as counter-party risks are prevalent. On the other hand, access to carbon accounting solutions that offer integrated carbon offsetting features is low globally. Our flagship product, Erguvan Marketplace is a secure and transparent carbon credits trading platform that directly connects end buyers and project developers, offering all participants a frictionless, efficient and low-cost transaction environment. We also provide a suite of activity-based carbon accounting APIs with seamless carbon offsetting features.
