•Vessel inputs
–Auxiliary engine load factor at berth, or “hoteling” (%)
–Auxiliary engine emissions factors (g/kWh)
•Activity inputs
–Vessel port calls per year
–Hoteling hours per port call
•Shore power inputs
–Electricity generation by facilities contributing to the shore power system (MWh)
–Emissions by facilities contributing to shore power system
•e.g., metric tons of SO2, NOx, PM10, PM2.5, CO, CO2)
–Electrical power generation emissions factor
•Output:
Difference = Vessel Emissions -Shore Power Emissions
Shore Power & Diesel Emissions Estimate
