This bill would let Massachusetts borrow nearly $4 billion to help communities prepare for and respond to climate threats. The bill funds a wide range of initiatives, including flood and dam repairs, coastal defenses, tree planting in underserved and high-risk areas, and clean water projects—such as PFAS cleanup and improvements to school drinking water. Additional investments support parks, farms, fisheries, and the development of green, affordable housing. The bill also aims to reduce waste by restricting single-use plastic bags and small hotel toiletries, requires home sellers to disclose flood risks, and streamlines permitting for both resilience and housing projects.
