The bill establishes the Green School Works Program, which provides competitive grants to K-12 public schools and districts for projects focused on installing or maintaining clean energy infrastructure. This initiative aims to enhance energy efficiency, reduce carbon emissions, and address climate change impacts, including necessary construction or repair costs for school rooftops. The Department of Elementary and Secondary Education (DESE) will administer the program in collaboration with the Massachusetts Clean Energy Technology Center, prioritizing projects from schools that serve low-income and environmental justice populations. Additionally, the bill mandates annual reporting by the DESE commissioner to legislative committees on grant awards, ensuring transparency and accountability.

Funding allocations are specified for various public schools in Massachusetts to implement energy-efficient upgrades, including the installation of air source and ground-source heat pumps. Notable allocations include $2,732,994 for Barnstable United Elementary School and $5,000,000 for the Horace Mann Laboratory School, both aimed at enhancing energy systems for specific grade levels. The bill also introduces new grade specifications for schools receiving funding, such as "grades pre-K through 12th" for the Jeanne D'Arc School and "grades 6th through 8th" for the Plouffe Middle School. Furthermore, provisions for technical assistance are included, focusing on renewable energy analysis and geothermal heat pump feasibility studies to support schools in their decarbonization efforts.
