In previous CFIRE-funded research, emissions calculation methodologies were developed to forecast freight-related emissions of criteria air pollution and greenhouse gases. While simple emission factors exist, these new methodologies are unique because they incorporate location-specific, speed-dependent data for freight transport. This data can be coupled to speed dependent emission factors to produce a much more rigorous emissions inventory that reflects location-specific driving conditions. Because fuel economy and combustion vary considerably with speed, these inventories should improve accuracy considerably if they can be properly customized. The goal of this work is to provide a web-based tool for easy estimation of fleet emissions using state-specific data, and also enable further customization to reflect driving conditions by individual fleet managers.


This technology transfer project will develop a web-based fleet emissions calculator for posting on the CFIRE website. The website will provide simple and customizable access to the emissions estimation methodology developed under previous CFIRE project work.


  1. Translate Emissions Estimation Spreadsheet into Model Code – Project effort for this task will translate the existing project spreadsheets into a model characterizing the input variables, calculation methods, and output metrics. The resulting model will be designed to assess emissions over a range of fuel, technology, or driving conditions – submitted as user inputs.
  2. A web-based application (app) will be developed to provide user friendly controls to interact with the emissions calculator model developed as Task 1. The app will consist of: 1) a web-based graphical user interface (GUI) to incorporate user-defined input variables, and 2) the emissions calculation model to estimate emissions and returning results.
