1) This workpaper uses a tool designed by Union Pacific to help estimate the potential emissions associated with freight by rail transportation. The data, results and/or other information generated by this calculator, as well as the underlying methodology and mathematical assumptions which govern operational performance, have not been independently verified.
2)Estimates use system averages; level of precision results in limitations for formal reporting. Actual emissions and savings may vary based on routing and other factors. Train Category is not considered and hence estimate is approximate.
