You probably already know that Barcelona has a low emission zone, in which only accredited vehicles that produce low emissions according to the criteria of the DGT (Dirección General de Transporte) can enter. If your car is registered in a country other than Spain, you should know that your car can circulate within the ZBE (low emission zone) if it complies with the European Union's low emission criteria and provided that you obtain a permit. To do this, you must check the conditions to drive foreign vehicles within the ZBE and apply for your permit on this same page, following the instructions detailed there.
