Develop a Port Emissions Inventory

CRT and EDF believe that, in order to create meaningful and realistic goals for air quality improvement from its drayage truck fleet, each port community must first have an understanding of the size and age of the fleet serving its port.  That is why the Clean Trucks Initiative supports the implementation of an emission inventory from drayage trucks serving individual port communities.  Not only is the emission inventory a critical component to measuring the amount of pollution that is attributable to port trucks, but it allows each port to set measurable, metrics-based goals for reducing a variety of diesel pollutants including NOx and PM.  

The most effective way to implement a port emission inventory is through the implementation of a drayage truck registry system.  The truck registry collects basic information from each truck that calls on a port, such as the model year of the truck engine and the number of visits per year each truck makes to the port.  This information is then aggregated across the entire drayage fleet serving the port in order to develop a port-wide emission profile that serves as the baseline for comparing subsequent air quality improvements.  Once a drayage truck registry is established, the system can then be used to monitor progress in reducing drayage truck emissions through the retirement of older-higher polluting trucks and the deployment of newer, cleaner trucks.
