Bus Programs

The ARB staff, in coordination with the California Energy Commission and the local air pollution control districts, have developed guidelines to establish a Lower-Emission School Bus Program. The guidelines provide criteria for the purchase of new school buses and retrofits of existing school buses to reduce particulate matter emissions. The bus replacements and retrofits of existing school buses will reduce school children's exposure to harmful diesel exhaust emissions. Sign up for the e-mail list.
