This bill aims to prevent local governments in Michigan from enacting ordinances that regulate energy emissions or impose any fees, charges, or taxes related to emissions and energy consumption metrics. Specifically, it prohibits local units of government from imposing a "carbon tax," "energy consumption metric tax," "vehicle-miles-traveled tax," or any mandatory emissions trading programs. Additionally, any existing local regulations that conflict with this bill will be rendered null and void.

The bill also provides a mechanism for enforcement, allowing the attorney general or any aggrieved individual to file a lawsuit in circuit court to challenge any local ordinance that violates this act. If a plaintiff other than the attorney general wins the case, they are entitled to reasonable attorney fees and costs. Furthermore, local governments are prohibited from using public funds to enact or defend any regulations that contravene this legislation. The act is set to take effect 90 days after being enacted into law.
