The Port of Long Beach is committed to improving air quality and reducing the impact of goods movement through their port. To facilitate this, the Port conducts an annual inventory of air emissions from port-related sources to track progress for improving air quality and reducing health risks to surrounding communities. The Port's current findings show that the introduction of new generation diesel trucks has generated substantial clean air benefits for communities located near their freight facilities compared to previous levels.
The current emissions inventory released from the Port of Long Beach demonstrates the impact of introducing the latest clean diesel technology contributed towards substantial air quality improvements for communities located near freight facilities. In 2019, trucks serving the Port generated only 7 tons of fine particle (PM 2.5) emissions, a significant reduction from the nearly 200 tons produced in 2005. This reduction is despite a 14 percent increase in cargo volumes and largely due to the introduction of new technology diesel trucks.
The Port of Long Beach - Clean Trucks Program, instituted jointly by the Ports of Long Beach and Los Angeles, requires that all trucks meet the latest tailpipe emissions standard for PM 2.5 and new trucks entering service in the port as of 2018 must meet the near-zero tailpipe emissions standard for ozone-forming compounds (NOx) as well. According to the latest data, 90 percent of the estimated 14,000 port trucks entering and exiting marine terminals in southern California are powered by diesel and about 65 percent are of the latest generation diesel technology. The remaining ten percent are primarily natural gas-powered vehicles. This is significantly better than California state, where only 36 percent of trucks are the latest generation diesel.
This newly published data demonstrates the impact the turnover of the latest generation diesel technology can have on frontline communities located near freight facilities as well as the states and regions across the country.
