As of today, the city administration of Barcelona has banned the use of vehicles, the biggest polluters, in an effort to reduce high emissions of harmful gases.
Under the new regulations, diesel vehicles registered in Spain before 2005 or 2006, and petrol vehicles registered before 2000 are no longer allowed to drive from Monday to Friday from 7.00 to 20.00 in the city of 1.6 million inhabitants.
Owners of these vehicles can apply for ten days of driving license per year.
Owners of foreign vehicles should seek permission from the city authorities to use them in the no-go zone in Barcelona with the threat of a fine of at least 100 euros.
From 2021, the most polluting vans, trucks and buses will fall under the same ban.
According to city officials, the ban covers 50,000 vehicles a day and will reduce nitrogen dioxide emissions by 15 percent.
The capital of Spain, Madrid, from a year ago, limited driving in the historic center to those who live in that part, while those who are not residents can use vehicles if they do not pollute, ie if they are hybrid or electric.
This is a much more restrictive measure than for Barcelona, but the zone to which it applies is much smaller.
Barcelona Mayor Ada Cholau also hinted at the possibility of introducing a charge to enter the city from July, as do other European metropolises such as London, Stockholm and Milan.
According to the latest report from 2017, Barcelona since 2002 exceeds the level of small particles allowed by the International Health Organization and the level of carbon dioxide determined by Brussels.
At the end of July, the European Commission sued Spain in the European Court of Justice as one of the last countries from which Brussels asks to respect the laws related to air quality.
