The Climate Action Incentive Fund (CAIF) was a federal program supporting municipalities, schools, hospitals, and other public facilities in reducing greenhouse gas emissions. The program funded retrofits and upgrades to improve energy efficiency in publicly-owned buildings, helping these institutions reduce operating costs while lowering emissions. Such programs recognize that public buildings represent significant emission sources and that public institutions often lack capital for efficiency investments despite long-term savings potential. Federal support for municipal climate action acknowledges that local governments are on the front lines of both emission reduction and climate adaptation, requiring resources to act on commitments.
