    u California Environmental Protection Agency (CARB)

    u California has the right to set its own legislation concerning OBD

    u Today the OBD requirements defined by the CARB are not only valid for the state California but for the overall US

    u CARB always leads the debate in the US, the other states follow

    u European Union (EU)

    u EU has defined its own set of OBD requirements which are based on the CARB OBD II requirements but are not identical

    u This version of OBD II is called EOBD (European OBD)
