Abstract: Novel solutions to the challenges of obtaining accurate information about a user's or an organization's carbon footprint. In some cases, these solutions can obtain and/provide feedback about a user's carbon output based on the user's habits and choices. Some solutions are designed to supply services to individuals as well as commercial ventures and for a variety of vehicle fleets, including without limitation construction equipment. In different aspects, systems in accordance with various embodiments enable a variety of types of users to create their own carbon emission generation profile based on vehicle type; track, estimate, and store their emissions in a database; analyze their results and performance, using established methods and metrics and/or automatically update all operating parameters of interest.
