What's New in this Version?
Version 2.0.18 of the Rail Tool contains updates and revisions to the prior version, 2.0.17. These updates
have been implemented to enhance the usefulness, clarity and accuracy of the Tool, and are
summarized below:
US EPA secured the World Resources Institute (WRI) to conduct a review of the underlying
methodology, calculation process and supporting technical documentation of the SmartWay Rail Tool,
and it was found to be in conformance with the requirements set forth in the GHG Protocol Corporate
Accounting Standard. New outputs are now available in the optional report section of the Tool providing
Scope 1, Scope 2, biogenic, and non-carbon emissions for public disclosure, consistent with WRI and
Carbon Disclosure Project requirements.
Removed the "Cars" screen for Class 1 carriers that required entering railcar miles and volume by railcar
type. This has been replaced with a simple input field for total railcar miles.
The grams per truck-equivalent-mile metric included in the reports is now calculated with default
volume values for all carrier classes.
Updated the grams per kilowatt-hour emissions factors used for electric locomotives.
Miscellaneous text and format updates for clarification.
