The MBTA governing board shall direct the MBTA to update and operate existing zero-emission vehicle infrastructure and to expand its zero-emission infrastructure. Removal of existing zero-emission infrastructure shall be permitted for temporary road, catenary, or public utility work. Any replacements for electric vehicles in operation must meet or exceed the availability of the current zero-emission fleet, with no auxiliary systems. For all diesel-electric hybrid buses, the MBTA shall develop robust monitoring about the locations where such buses are operating on diesel power versus electric power and provide this data to the public on a timely basis.

The MBTA governing board shall direct the MBTA to operate electric buses with a priority for operating such buses on routes serving environmental justice populations. The MBTA governing board shall direct the MBTA to operate electric buses on bus routes serving residents of Chelsea, Everett, Revere, Somerville, Chinatown, Roxbury, Dorchester, Lynn, and Mattapan by 2025. The MBTA governing board shall direct MBTA staff to conduct robust community outreach and engagement with residents of environmental justice populations, municipal officials in cities and towns that have environmental justice populations, and with transportation and environmental justice advocates. The MBTA staff shall report to the MBTA governing board at least six times per year the progress of electrifying the bus and rail fleet. As part of the public reports, MBTA staff shall explain the cost analysis of all procurements of fossil fuel infrastructure and the reasons for procuring fossil fuel infrastructure in lieu of zero-emission infrastructure.

The MBTA governing board shall electrify the commuter rail fleet in two phases.  Phase I includes electrification of the Providence Line, Fairmount Line, and Newburyport / Rockport Line at least through the Beverly Depot Station by December 31, 2024. Phase II includes electrification of the Framingham/Worcester Line by December 31, 2026; Middleborough/ Lakeville Line by December 31, 2027, and the remaining routes that pass through environmental justice populations, but do not offer passenger service by December 31, 2035:
