Building, along with transportation, make up nearly 99% of Boston’s carbon emissions. The legislative package includes multiple efforts to reduce emissions, including a play to get the state to have net zero greenhouse gas emissions by 2050. Also included in the bill is a plan to jump-start efforts to supply low-cost solar electricity to low-income communities, setting a deadline for converting MBTA buses to all-electricity power and a goal of getting an entirely zero-emissions fleet by 2040.
Existing state law- the 2008 Global Warming Solutions Act – set the goal of reducing greenhouse gas emissions to 80% below 1990 levels by the year 2050. The package of bills unveiled Thursday would effectively set a goal of 100% below the 1990 levels.
