|Authorities in Mexico City have temporarily ordered all cars to remain idle one day a week in response to this notoriously smoggy capital’s worst air-quality crisis in over a decade.|
|A Phase 1 emergency due to high ozone levels – the first since 2005 – was declared two weeks ago, when warm temperatures and still air left pollution trapped in Mexico City’s volcano-ringed valley. Government officials and environmental activists pinned at least some of the blame on a supreme court decision last year that overturned a rule barring all cars over eight years old from the streets one day a week.|
The ruling is said to have put an extra 1.4m vehicles back on the roads each day. Starting on 1 July, more modern technology will be put in place at smog-check centres. Vehicles are supposed to get checked every six months, though it’s common knowledge that for a bribe of $20 or so drivers can ensure a car comes out “clean”.
