An Act to create the buy clean Massachusetts program

HD 3507 creates Massachusetts' "Buy Clean" program requiring contractors on large construction projects to provide environmental impact data for specific building materials. It applies to projects over 50,000 square feet, major renovations, or transportation infrastructure costing over $3 million, affecting contractors working on state-funded construction. Starting July 2027, contractors must submit environmental product declarations (showing carbon emissions) and health declarations for covered materials like concrete, steel, and engineered wood before project completion. The law includes provisions for small businesses to receive financial assistance to offset costs of creating required environmental reports. The program aims to reduce greenhouse gas emissions from construction materials by making environmental data mandatory for state procurement.
