An Act to further empower local climate action

This bill (SD 1591) amends Massachusetts' climate demonstration project rules to allow up to 20 cities and towns to participate (increasing the limit from 10). It requires participating cities/towns to first meet housing affordability standards - either by meeting a 10% affordable housing threshold under Chapter 40B or approving zoning that permits multi-family housing without age restrictions for families with children. Cities that already met the housing threshold by December 21, 2020, are exempt from this requirement. The Department of Energy Resources must issue implementing regulations by July 1, 2026.
