Notice of Availability of Programmatic Assessment of Greenhouse Gas Emissions From Transit Projects
Notice of availability; Request for comments.
The Federal Transit Administration (FTA) announces the availability of a draft Programmatic Assessment of Greenhouse Gas Emissions from Transit Projects (Programmatic Assessment) and an accompanying Greenhouse Gas Emissions (GHG) Estimator Tool (Estimator Tool). The purpose of the draft Programmatic Assessment is to: (1) Report on whether certain types of proposed transit projects merit detailed analysis of their GHG emissions at the project-level; and (2) provide a source of data and analysis for FTA and its grantees to reference in future environmental documents for projects where detailed, project-level GHG analysis would provide limited information beyond what is collected and considered in the assessment. The draft Programmatic Assessment presents estimates of GHG emissions generated from the construction, operations, and maintenance phases of projects across select transit modes, as well as an estimate of personal vehicle emissions displaced due to transit's ``ridership effect.'' The associated Estimator Tool is a spreadsheet tool that allows users to calculate partial lifecycle GHG emissions estimates by transit mode based on limited data inputs. FTA's draft Programmatic Assessment or Estimator Tool is not a requirement; agencies and states may use other methods for reporting GHG emissions related to state GHG reporting regulations, as needed and as appropriate. Use of FTA's draft Programmatic Assessment or Estimator Tool is not a requirement, if agencies and states are utilizing other methods for reporting GHG emissions related to state GHG reporting regulations. The FTA requests public comments on the Programmatic Assessment and the Estimator Tool.
