The Dutch city of Utrecht aims to ban old polluting cars from its centre to improve the local air quality.All diesel vehicles that are over eight years old will be banned from the city centre. Later, the same ban will apply to cars with petrol engines that are above twelve years old. By implementing the measure, Utrecht aims to meet the EU requirements for air quality. Utrecht is the first city in the Netherlands to implement the environment-friendly measure. Earlier, the capital Amsterdam made a similar attempt, but found its plans cancelled due to large protests.
