CARB is the acronym for the California Air Resources Board.
For over three decades, CARB has played a leading role in testing and approving gasoline vapor recovery equipment. Vapor recovery enforcement agencies in other states, to avoid duplicating work already done in California, often rely on CARB-approved equipment or procedures. If CARB has tested and approved certain types of nozzles and hoses, for example, this equipment may be referred to as having been “CARB certified.”
Other states or municipalities, in turn, may specify that only “CARB-certified equipment” may be used in vapor recovery installations within their jurisdictions.
