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:
