GHG Performance Calculator
This is a draft release of the GHG Performance Calculator.
This tool was developed for testing the sensitivity of the GHG measure calculation to various inputs. It is not intended as an authoritative calculation of the proposed GHG measure. Questions? Comments? Contact Matt Hardy (AASHTO) or William Robert (Spy Pond Partners, LLC) for more information on the GHG Performance Calculator.
On July 7, 2022 FHWA announced a Notice of Proposed Rulemaking (NPRM) for states and municipalities to track and reduce greenhouse gas (GHG) emissions. This spreadsheet tool is designed to help DOTs and MPOs project GHG emissions based on fuel consumption. Fuel consumption is assumed to vary based on fleet fuel efficiency, EV adoption, and miles traveled. Draft technical documentation is available here.
