Los Angeles Retires Last Diesel Bus for CNG

The Los Angeles County Metropolitan Transportation Authority last week officially (and ceremoniously) retired its last diesel passenger bus.  The LA MTA now has 2,221 compressed natural gas buses to go along with six gasoline-electric hybrids and one electric bus.  The main motivation in Los Angles is air pollution:
"Transit officials estimate that the elimination of diesel engines has reduced the release of cancer-causing particulates from the bus fleet by 80% and greenhouse gases by about 300,000 pounds a day in one of the smoggiest areas of the country."
Los Angeles is not the first city to fully scrap its diesel fleet, but it does have the largest collection of CNG buses in the country.
