FTA's Transit Greenhouse Gas Emissions Estimator

The Transit Greenhouse Gas (GHG) Emissions Estimator is a spreadsheet tool that allows users to estimate the partial lifecycle GHG emissions generated from the construction, operations, and maintenance phases of projects across select transit modes. The tool was developed in connection with the Greenhouse Gas Emissions from Transit Projects Programmatic Assessment. The tool provides a resource to generate coarse but informative estimates of GHG emissions using limited project information and can be used for a broad range of transit projects. This tool is not mandatory; transit agencies should work with the appropriate FTA regional office to determine whether to conduct project-specific analyses of GHG emissions and the best approaches.
