GHG Calculator

GHG Calculator

The Transportation GHG Calculator is a state-level spreadsheet tool for estimating GHG emissions based on the Federal Highway Administration's detailed methodology in their national performance and emissions measure rule.

This tool was developed for calculating base year (2022) GHG emissions and testing the sensitivity of future GHG emissions to various inputs. Questions? Comments? Contact Anna McLaughlin (AASHTO) or William Robert (Spy Pond Partners, LLC) for more information on the GHG Calculator.
