Southeast Michigan, as the state’s largest metropolitan area, has a complex transportation network vital for our economy, trade, prosperity, and quality of life. However, this network can also contribute significant vehicle emissions, which affects our regional air quality. To combat this, SEMCOG manages two key programs aimed at reducing vehicle emissions: the Congestion Mitigation and Air Quality (CMAQ) Improvement Program and the Carbon Reduction Program.

Congestion Mitigation Air Quality (CMAQ)

The Congestion Mitigation and Air Quality Improvement (CMAQ) Improvement Program funds transportation projects that help meet national air quality standards. This federally funded program focuses on improving air quality and reducing traffic congestion. SEMCOG administers the CMAQ program for Southeast Michigan, working with local road and transit agencies to develop projects that enhance air quality.

Carbon Reduction Program

The Carbon Reduction Program (CRP), a newer program established by the Infrastructure Investment and Jobs Act in 2021, provides funding for projects that reduce carbon dioxide emissions from on-road vehicles. SEMCOG’s Regional Review Committee awarded CRP funding for projects in Southeast Michigan for fiscal years 2023-2026. You can find the awarded projects in the documents below:
