Massachusetts was actively engaged on many of the most important cases, with some of them running through the New England federal courts and Attorney General Andrea Campbell’s office often wading in, typically with a coalition of blue state attorneys general.

Starting in 2024, a group of 10 Massachusetts communities kickstarted a first-of-a-kind experiment by pledging to go fossil fuel free. But moving off gas for new buildings doesn’t preclude the utilities from needing to spend tens of millions of dollars each year upgrading the existing infrastructure by replacing pipes. This week on The Codcast, CommonWealth Beacon reporters Hallie Claflin and Jordan Wolman discuss Wolman’s latest piece uncovering how gas companies have spent $100 million on natural gas infrastructure in nine of those 10 communities, roughly since they adopted their fossil fuel-free ordinances.
