Relating to the authority of a political subdivision to use public money for an environmental project.

HB 4313 prohibits Texas political subdivisions (like cities and counties) from imposing fees to fund climate or environmental projects. The bill defines such projects as those reducing greenhouse gases, adapting to climate change, or reducing pollutants, but explicitly excludes basic sanitation and waste disposal. It bans fees, charges, or assessments for these specific initiatives, effective September 1, 2025. This directly affects local governments seeking to finance climate-related work through user fees. The law does not restrict general public funding or other project types.
