AN ACT CONCERNING HYBRID SCHOOL BUSES.

This bill updates Connecticut's school bus regulations to allow hybrid buses alongside zero-emission and alternative fuel vehicles, aiming to reduce emissions while providing flexibility for school districts. It defines hybrid school buses as vehicles that combine a combustion engine with an electric motor and battery system, and establishes a grant program to help municipalities, school districts, and operators purchase these buses and related charging infrastructure. The legislation creates a new state account to fund administrative costs and technical assistance for transitioning to cleaner school bus fleets, with priority given to projects serving environmental justice communities. Key deadlines require 100% of school buses to be zero-emission, alternative fuel, or hybrid by January 1, 2040, though the bill includes proposed deletions that would have required 100% zero-emission buses by 2030 in certain areas.
