State Senate Plan Calls For Net-Zero Emissions By 2050

State leaders are pledging to bring Massachusetts' carbon emissions down to net-zero by 2050.

Governor Charlie Baker announced the goal in his State of the Commonwealth address Tuesday — and Senate leadership released its own package of climate legislation Thursday.

It calls for all-electric MBTA buses, carbon pricing and a new government watchdog group.

State Senator Michael Barrett, one of the architects of the plan, joined WBUR's Morning Edition to discuss the ambitious legislation.
