Until late 2007, the passenger car registration tax was linked to the cylinder capacity of the vehicle. From 1st January 2008, Law 34/2007 on Air Quality and the Protection of Atmosphere establishes a new calculation method for the registration tax of passenger cars in Spain, linked to car CO2 emissions/fuel consumption. In December 2008, the new tax scheme was extended to two-wheeled vehicles such as motorcycles.(For more detail on rates, see reference below.)
