Evaluation of Existing and Promising Technologies to Reduce Emissions Associated with Freight Movement at the Ports


The objective of this project is to test the emissions of existing and promising technologies that offer the potential for further reductions in the emissions associated with freight movement at the ports. Testing would provide direct measurements of the in-use emissions of criteria pollutants (CO, NOx, PM2.5, THC), long-lived climate pollutants (CO2), short-lived climate pollutants (black carbon, methane) and air toxics, as needed. The sources of primary interest include scrubbers, LNG vessels, as well as, the use of non-distillate fuels on ocean-going vessels (OGVs) and the engines associated with cargo handling equipment (CHE), and/or commercial harbor craft (CHC). While there are many available technologies to focus on that have been successful in reducing criteria pollutants such as PM, SOx and NOx, further reductions are needed to help achieve California’s air quality, climate, and public health mandates. In particular, additional efforts need to be directed towards the reduction of greenhouse gases (GHG), including short-lived climate pollutants (SLCPs), from the freight movement system.
