Extends program to cut diesel pollution for five more years

This bill would extend a program that helps reduce harmful diesel pollution across the country. It would allow businesses and local governments to keep getting support for projects that make diesel engines cleaner, potentially improving air quality for many Americans until 2029.

What Would Change

Currently, the federal program that helps reduce diesel emissions is set to end in 2024. If this bill passes, the program would be allowed to continue until 2029, extending its work by five years.
