News about the Crit'Air, the environmental zones and air pollution
The recent announcement by the City Government of Barcelona about traffic prohibition for vehicles older than 20 years has been polemic. However, experts have already made it clear that banning old vehicles will not be enough from itself. Andrés Alastuey, an expert from the Spanish National Research Council (CSIC), asserts that “if anything has been proved by the dieselgate of the Volkswagen emissions it’s that we don’t have the technology to measure and reduce real vehicle emissions”. The most effective solutions, according to experts, would be to ban the entry of vehicles to the city altogether.
