PROJECTS IN PROGRESS
Carbon Footprinting
Carbon footprinting is used to determine emissions sources, track emission trends, and provide information needed to determine where ports can focus efforts to reduce their greenhouse gas (GHG) emissions.
A carbon footprint is the amount of GHG emissions an individual, organization or event directly or indirectly releases over a measured period.
Whether ports choose to monitor emissions associated with their landside operations or to extend their boundary to monitor emissions of ships and other equipment outside of their immediate boundaries, development of a carbon footprint will serve as a valuable tool to identify GHG emissions.
From there, a carbon management strategy can be created and implemented to reduce port GHG emissions.
The WPCI Carbon Footprinting Work Group released a Guidance Document that serves as a reference for ports looking to develop or improve their GHG emissions inventories.
For questions or comments about the Guidance Document, please contact Lisa Wunder at lwunder@portla.org.

CO2 Calculators:
The Port of Los Angeles has developed Port-related CO2 calculators to allow users to estimate their carbon footprint for Scopes 1 & 2 and Scope 3 (under construction).
Scopes 1 & 2 CO2 Calculator
This calculator focuses on Scopes 1 & 2 Port-related municipal sources and utilizes a simplified fuel consumption-based approach and energy consumption. Fuels included are diesel, gasoline, natural gas, liquefied petroleum gas (LPG), liquefied natural gas (LNG), compressed natural gas (CNG), biodiesel, and ethanol. Grid powered energy consumption is input as well. Users provide fuel and energy consumption values for the various Scopes 1 & 2 sources.
Scope 1 - Port Direct Sources. These sources are directly under the control and operation of the port administration entity and include port-owned fleet vehicles, port administration owned or leased vehicles, buildings/stationary sources (e.g., boilers, furnaces, etc.), port-owned and operated cargo handling equipment and harbor craft (to the extent the port is an operating port), port employee vehicles and any other emissions sources that are owned and operated by the port administrative authority.
Scope 2 - Port Indirect Sources. These sources include port purchased electricity for port administration owned buildings and operations. Tenant power and energy purchases are not included in this Scope.
The calculator estimates CO2 emissions and allows for comparing existing or baseline conditions to user-developed emission reduction scenarios utilizing various control strategies (primarily switching fuel types and technologies such as hybrids and electric). The calculator is provided in English Unit and Metric Unit versions following the links below:
This versions of the calculator provides the user the full use of the calculator, however this public version of the calculator does not permit the saving of entered information or results. Results can be printed for retention or comparison purposes. If a user is interested in the full version of this calculator that can save results and export to excel, please see the attached Order Form.
