"Facing the rising threat of wildfire and extreme drought, Flagstaff, Ariz., unveiled an ambitious effort two years ago to cut the heat-trapping emissions that drive climate change.
A critical part of Flagstaff's climate plan proposed that all new construction get to net-zero greenhouse gas emissions by 2040 and that the city promote "aggressive building electrification" to decrease reliance on fossil fuels. As in many places, buildings are a big source of Flagstaff's greenhouse gases, mainly because many are heated by burning natural gas.
But in February 2020, the Arizona Legislature blocked much of Flagstaff's plan for its buildings. With the backing of the state's main gas utility, the Legislature passed a bill that prevents municipalities and counties from banning new gas infrastructure and hookups."
