Facility-Based Mobile Source Measure focused on reducing emissions associated with vehicles and mobile equipment operating in and out of warehouse distribution centers.


With consumer demand for online retail and just-in-time delivery increasing, goods delivered between the region’s seaports, airports, and businesses across the nation may increase mobile source emissions, even with the deployment of newer, cleaner vehicles and equipment.  The goal of this measure is to assess and identify potential actions to further reduce emissions associated with emission sources operating in and out of warehouse distribution centers.
