Key Points

This bill extends a federal program that helps pay for cleaner engines in older trucks, buses, and construction equipment. It keeps the program running for five more years through 2029.
The program gives out grants and loans to help local governments and businesses replace old, smoky diesel engines with newer versions that produce less pollution. This is often used for school buses and equipment at shipping ports.
By getting rid of older engines, the program helps clean up the air in neighborhoods near highways and shipping centers. This can lead to fewer health problems like asthma for people living in those areas.
