In an effort to reach their carbon emissions targets, parking meters in Madrid charge polluting cars more. While electronic cars park for free and hybrids receive a 20% discount, cars that pollute more receive a marked up rate. Madrid city officials are calling the smart parking meter system the first of its kind. Effective June 1, drivers will begin paying rates based on the year of the car's make and its engine.
This is all in an effort to reduce air pollution levels, which are consistently higher in Madrid compared to the European Union average. Using parking fees to encourage environmentally friendly vehicles is one way to curb pollution and help reach established carbon emissions targets.
