The Town of Arlington, Massachusetts commissioned CMTA, Inc. to develop an Electrification & Air Quality Master Plan to help meet its goal of achieving net-zero greenhouse gas emissions by 2050. This plan provides a comprehensive roadmap for decarbonizing six municipal schools by transitioning to all-electric systems, phasing out fossil fuel use, and improving indoor air quality. It outlines how the town can align equipment replacement cycles, scheduled renovations, and targeted energy efficiency improvements with long-term capital planning and available state funding. Each school is given a tailored implementation timeline, with interim targets like electrifying heating systems and replacing gas stoves with induction units. The Master Plan offers valuable insights for local governments, facilities managers, and sustainability professionals looking to structure electrification and decarbonization projects within broader decarbonization goals, and budget and operational constraints.
