On May 31, 2018, the Federal Highway Administration (FHWA) published a final rule in the Federal Register repealing the performance management measure in 23 CFR 490.507(b) 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.
By repealing the GHG measure, FHWA will no longer require State DOTs and MPOs to undertake administrative activities to establish targets, calculate their progress toward their selected targets, report to FHWA, and determine a plan of action to make progress toward their selected targets if they failed to make significant progress during a performance period. (See 23 CFR 490.105, 107, 109.)
