The Port of Los Angeles has, as part of the World Ports Climate Initiative, developed a carbon calculator for ports to determine greenhouse gas emissions from their operations and explore reduction strategies.

The free carbon calculator – available at http://wpci.nl/projects/carbon_footprinting.php - allows ports to estimate existing carbon dioxide emissions from direct, port-owned sources such as fleet vehicles, cranes, harbour craft and cargo handling equipment, and also indirect sources such as electricity purchased for the port-owned buildings and operations.
Facilitated through the International Association of Ports and Harbors, over a dozen port authorities and organisations have collaborated on the project. If users want to save or export data, an enhanced version of the calculator is available for a one-off fee of $450.
