National Performance Management Measures; Assessing Performance of the National Highway System, Freight Movement on the Interstate System, and Congestion Mitigation and Air Quality Improvement Program

This final rule repeals the performance management measure that assessed the percent change in tailpipe carbon dioxide (CO2) emissions, from the reference year 2017, on the National Highway System (NHS) (also referred to as the Greenhouse Gas (GHG) measure). The GHG measure was one of several performance measures that FHWA required State departments of transportation (State DOTs) and metropolitan planning organizations (MPOs) to use to assess performance in a variety of areas. After considering the comments received in response to the notice of proposed rulemaking (NPRM) published on October 5, 2017, FHWA has decided to repeal the GHG measure.
