Congestion Mitigation Air Quality (CMAQ)
The Congestion Mitigation and Air Quality (CMAQ) Improvement Program was created in 1991 under the Intermodal Surface Transportation Efficiency Act (ISTEA) to support surface transportation projects and other related efforts that contribute air quality improvements and provide congestion relief. The Carbon Reduction Program (CRP) was created under the Infrastructure Investment and Jobs Act (IIJA) and designed to provide federal funding to projects that decrease transportation related carbon emissions that result from on-road, and highway sources.
