Every day, children travel to and from schools on diesel fueled buses that are harmful to their health. The Healthy Environments for Learning Day (HELD) 2023 campaign is promoting the shift from diesel powered to electric school buses across the country. Diesel fuel still powers most of the school buses across the country, generating diesel exhaust emissions that negatively affect the health of children on board the buses and on school grounds, as well as bus drivers, school personnel, and neighbouring communities.
