SECTION 1. The purpose of this act is to transition the commonwealth to 100 per cent clean energy for electricity by 2035 and 100 per cent clean energy for the building sector and transportation sector by 2045 in order to: (1) protect the health and safety of all residents of the commonwealth by eliminating pollution that is contaminating our air, water and land, and changing our climate in dangerous ways; (2) maximize the ability of the commonwealth to meet the greenhouse gas emissions limits adopted under chapter 21N of the General Laws; (3) improve quality of life and economic well-being for all, with an emphasis on environmental justice populations that have been disproportionately affected by pollution and energy costs; (4) increase energy security and energy affordability by reducing the commonwealth’s reliance on imported fuels and increasing renewable energy generation in the region; and (5) stimulate investment and create local jobs by harnessing the commonwealth’s skilled workforce, business leadership and academic institutions to advance renewable energy technologies.

SECTION 2. The General Laws are hereby amended by inserting after chapter 25C the following chapter:-
