U.S. Court rules in favour of barring diesel purchases for fleets
Sacramento, California – A rule adopted by California’s South Coast Air Quality Management District (AQMD) targeting diesel-powered vehicles purchased for fleets has been upheld by the Ninth Circuit Court of Appeals, according to a report by the Green Car Congress. The rule had been challenged in court by the Engine Manufacturers Association (EMA) and the Western States Petroleum Association (WSPA).
AQMD adopted the fleet rules in 2000 and 2001, following a study showing that about 70 per cent of the total cancer risk from air pollution was due to diesel exhaust. The original seven fleet rules included transit buses, school buses, trash trucks, airport shuttles and taxis, street sweepers and heavy-duty utility trucks. The rules bar the purchase of diesel engines for use in those fleets, generally requiring operators to buy clean-fuel models when they replace or add to fleets of 15 or more vehicles. Most of the clean-fuel vehicles have been natural gas.
