CLEANER CARS, LOS AN­GE­LES

Hong Kong Tatler - - Features -

Ozone pol­lu­tion from cars in Los An­ge­les has been halved in the past decade, and is down a whop­ping 98 per cent since the 1960s, thanks to a range of re­cent reg­u­la­tions. Th­ese in­clude re­quir­ing all ve­hi­cles to be fit­ted with cat­alytic con­vert­ers, the use of cleaner fu­els, im­prove­ments in en­gine ef­fi­ciency and the pro­mo­tion of hy­brid ve­hi­cles.
