As part of a $500 million plan to clean up the ports of Long Beach and Los Angeles--which are significant sources of air pollution in the Los Angeles basin--half of the 16,000 diesel trucks that currently operate at the ports will be replaced with liquefied natural gas (LNG) models. With diesel at over $4 a gallon, many truckers have already been slowing down to save fuel, but no amount of slowing down can reduce the emission of conventional pollutants from the oldest trucks, which is the biggest problem currently facing the ports. Trucking companies, therefore, have finally agreed with the plan, and this October will begin replacing their oldest, most inefficient and dirtiest trucks. The goal is that by 2012 "only trucks meeting the EPA's 2007 clean air standards will be allowed in the ports." (It's not clear why trucks that don't meet those standards are currently allowed in the port, although it's probably a question of cost, as well as the fact that a significant potion of America's products enter through these two ports).
The Clean Air Action Plan will also require that ships turn off on-board systems while they are at the docks. Finally, the target for overall emissions reductions from the port is 45%, which includes an 80% reduction in truck emissions.
