Paris has barred some cars from its streets and has made public transportation free as it suffers from the worst and most prolonged winter pollution for at least 10 years, the Airparif agency said on Wednesday. The Independent reports: Authorities have said only drivers with odd-numbered registration plates can drive in the capital region on Wednesday. Drivers of even-numbered cars were given the same opportunity on Tuesday, but could now be fined up to 35 EUR if they are caught behind the wheel. More than 1,700 motorists were fined for violations on Tuesday. Paris mayor Anne Hidalgo said images of smog blanketing the capital were proof of the need to reduce vehicle use in the city center. The air pollution peak is due to the combination of emissions from vehicles and from domestic wood fires as well as near windless conditions which means pollutants have not been dispersed, the Airparif agency said. "This is a record period (of pollution) for the last 10 years," Karine Leger of AirParif told AFP by telephone. For more than a week, Airparif has published readings of PM10 at more than 80 micrograms per cubic meter of air particles, triggering the pollution alert. Along with odd-numbered cars, hybrid or electric vehicles as well as those carrying three or more people will be allowed to roam the roads. Foreign and emergency vehicles will be unaffected.
