Chicago Public Schools announced a $20 million grant from the Environmental Protection Agency on Tuesday that will allow the system to purchase a fleet of nearly 50 electric school buses over the next three years.

The announcement comes after the school system told parents that general education students would not receive busing for the rest of the school year. The grant aims to alleviate the stress on several CPS parents who are experiencing hourslong commutes due to a bus driver shortage, which has prevented CPS from providing transportation to students in previous years.
