Californian Air Resourses Board (ARB) offset credits are greenhouse gas (GHG) emission reductions or GHG removal enhancements that meet regulatory criteria and may be used by an entity to meet up to eight percent of its triennial compliance obligation under the Cap-and-Trade Program. Each ARB offset credit is equal to 1 metric tonne of carbon dioxide equivalent (CO2e) and can only be quantified using an ARB approved Compliance Offset Protocol. Once an ARB offset credit is issued, it may be used for compliance up to applicable limits with the Cap- and-Trade Program. To trade offset credits, projects must be located anywhere in the United States and its territories to be eligible under this protocol.
