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

HB 155 prohibits Texas local governments (like counties, cities, school districts, and special districts) from using public funds - such as taxes, fees, or grants - to plan, create, or operate most environmental projects. The bill allows exceptions only for specific cases, including flood control, renewable energy infrastructure for their own facilities, school energy efficiency programs, waste management, and projects required by state or federal law. It does not ban environmental work but restricts how local governments fund it, excluding projects like electric vehicle charging stations or general emissions reduction efforts. The law would take effect 91 days after the legislative session ends.
