Set Truck Retirement Goals
The model year of a port truck is the primary factor used to determine the amount of diesel pollution that a truck contributes to a port community. As illustrated in the chart below, newer trucks, and those trucks that are retrofit with diesel particulate filters (DPFs), produce significantly lower levels of criteria pollutants including NOx and PM.
Therefore, the CRT/EDF Clean Trucks Initiative gives ports the tools they need to set goals to retire older, higher polluting truck from port service, and replace them with newer, cleaner trucks. This is achieved by a port setting either voluntary or regulatory timelines for the progressive phase-out of port drayage trucks according to their model year. For example, CRT supported a truck phase-out timeline at the Port of Seattle that called for the retirement of all pre-1994 drayage trucks from port service by January 2011, then gradually ramped up to a requirement that all trucks serving the port must be model year 2007 or newer by 2018. The model year 2007 trucks reduce PM by 95% and reduce NOx by 80% when compared to their pre-1994 counterparts.
The Clean Trucks Initiative then provides public support from the shipping industry for the targets set by each port to meet their air quality goals, and CRT member companies drive compliance with those goals by deploying clean trucks in support of their freight movement. For example, after endorsing the truck retirement timeline at the Ports of LA and Long Beach, CRT member companies voluntarily deployed approximately 1,500 model-year 2007 emissions compliant trucks ahead of the programs deadlines. CRT member companies have even gone above and beyond the requirements of the program be deploying 300 trucks using alternative fuels (known as LNG, or liquefied natural gas) that are currently in service at those Ports.
