Officials from the ports of Long Beach and Los Angeles have approved a new plan that calls for aggressive cuts in pollution from ships and trains.
The plan approved Monday by the ports' harbor commissions seeks to clean up the air around the nation's busiest port complex.
It aims to reduce the health risks for people who live near the ports by giving incentives to shippers that bring newer vessels, which emit less pollution, to the ports. It also sets goals and standards to prompt railroads to bring cleaner-burning locomotives to the ports' rail yards.
For years, concerns about traffic and pollution hindered the expansion of terminals and operations at the ports, which move $300 billion in trade each year.
